Subject: [PATCH 001/885] feat: source payment terms, surcharge cap and default
 term from the merchant API
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

TWO-24814 / TWO-24952 / TWO-24859

The offerable payment terms, the buyer-surcharge cap and the merchant's
default term are per-merchant commercial values — they vary between
merchants of the same brand — so GET /v1/merchant is their authoritative
source, not brand.xml. Mirrors the minimum-order-value pattern already
in place.

- Add Service/Merchant/RecordProvider: one verify_api_key -> GET
  /v1/merchant fetch, cached + memoised per API key. Single source of the
  merchant record for every consumer.
- Add Service/Merchant/SettingsProvider: getAvailableTerms (available_terms),
  getSurchargeLimit (surcharge_limit), getDefaultTerm (due_in_days).
- MinimumOrderProvider now consumes RecordProvider (parsing only); the
  fetch/cache protocol moved into the shared provider.
- Admin payment-terms + surcharge-grid blocks and the AvailablePaymentTerms
  source model read the offerable terms and surcharge cap from the merchant
  API; the admin still narrows the buyer-facing term set.
- getDefaultPaymentTerm prefers the merchant's due_in_days when it is an
  offered term, else the existing admin/lowest fallback. SettingsProvider is
  injected into ConfigRepository via a \Proxy to break the construction cycle.
- Remove the now-unused getAvailablePaymentTerms / getSurchargeFixedMax from
  BrandRegistryInterface and its implementors, the Descriptor fields/getters,
  the Loader parse, and <available_payment_terms> from the vanilla brand.xml.
  brand.xsd keeps the elements optional for the transition.

magento-support-matrix.sh becomes a CLASSIFIER, not a filter. Every combo in
the support window is emitted tagged status=run|skip (+skip_reason); nothing
testable is silently green, nothing untestable silently vanishes.

- Support window now = current+prev2 over ALL minors. Image availability no
  longer slides the window: an in-policy minor with no CI image surfaces as a
  skip instead of being backfilled by an older out-of-policy minor
  (fixes the "window silently trails a minor behind" defect).
- Missing CI image auto-detected via `docker manifest inspect` (retry +
  fail-toward-run on a registry blip). Retires the hand-maintained
  image-exclusion list — the probe found the list was already stale
  (2.4.9 images DO exist for php84/php85; only php83 is missing).
- Intentional exclusions become reason-only, surfaced as visible skips.
- Retry + shape-validation added to the php.net and composer.json fetches
  (previously single un-retried calls); GH token no longer leaked to php.net.
- phpstan / di-compile gain a Classify first-step; skip legs record the reason
  to $GITHUB_STEP_SUMMARY + a ::warning:: and gate the remaining steps off.
- New coverage-report job renders a durable Magento×PHP status/reason table
  to the run summary (serves the merchant-troubleshooting flow).

Reference implementation; abn adopts the reconciled script in a follow-up.

 #
 # Strategy:
 #   1. Query github.com/magento/magento2 tags for bare-semver 2.4.x.
-#   2. Apply Adobe's lifecycle policy: current minor + N previous minors
-#      (default 2, ie. a 3-minor support window).
-#   3. Drop any version on `intentionally_excluded` (e.g. docker image
-#      not yet published by the CI-image maintainer).
-#   4. For each remaining Magento minor: fetch its raw composer.json
-#      and parse `require.php` to get the PHP constraint (e.g.
-#      "~8.2.0||~8.3.0||~8.4.0" → minors [8.2, 8.3, 8.4]).
-#   5. Query php.net/releases for currently-supported PHP minors
-#      (active + security). Intersect with the per-Magento constraint
-#      to drop combinations PHP itself no longer supports.
-#   6. Emit the cross-product as a GHA matrix.
+#   2. Support window = current minor + (SUPPORT_WINDOW-1) previous minors,
+#      taken over ALL minors. Image availability does NOT slide the window:
+#      an in-policy minor with no CI image is surfaced as a skip, it is NOT
+#      silently replaced by an older out-of-policy minor (TWO-24998 Defect 2 —
+#      "the window silently trails a minor behind").
+#   3. For each window minor: fetch composer.json, parse require.php → the
+#      PHP minors it accepts (e.g. "~8.2.0||~8.3.0||~8.4.0" → 8.2 8.3 8.4).
+#   4. php.net/releases → currently-supported PHP minors.
+#   5. Classify each (window-minor × accepted-PHP) combo, first matching wins:
+#        past upstream PHP support   — accepted by Magento but EOL per php.net
+#        intentionally excluded: ... — on the manual list (usually empty now)
+#        no CI image published       — deterministic image tag has no manifest
+#        run                         — otherwise
+#   6. Emit every combo with its status. The php-lint matrix is the union of
+#      php.net-supported accepted PHP minors — image-independent, since the
+#      lint / phpunit jobs use setup-php, not the Magento docker images.
 #
-# This replaces the hand-maintained EOL list AND the hand-maintained
-# min-PHP map with discovery from upstream (Doug 2026-05-22 follow-up
-# to r5 #10). The script is the single source of truth for which
-# Magento × PHP combinations CI exercises.
+# Replaces the hand-maintained EOL list AND the hand-maintained min-PHP map
+# with upstream discovery (Doug 2026-05-22, r5 #10). TWO-24998 additionally
+# retired the hand-maintained image-exclusion entries in favour of a docker
+# manifest probe (see intentionally_excluded + probe_image below).

Subject: [PATCH 003/885] =?UTF-8?q?ci(TWO-24998):=20split=20run/skip=20at?=
 =?UTF-8?q?=20matrix=20assembly=20=E2=80=94=20no=20green=20legs=20for=20sk?=

Content-Transfer-Encoding: 8bit

Reworks the earlier approach per review: a skipped combo must never appear as a
green test leg. The run/skip decision now happens entirely in the discover job:

- `--emit-matrix` returns RUNNABLE combos only; phpstan/di-compile legs are all
  real tests, so a green leg unambiguously means "tested". Dropped the per-job
  Classify step + proceed-gates (no longer needed).
- New `--emit-skips` returns the untestable combos with reasons. The discover
  job renders them to $GITHUB_STEP_SUMMARY as a coverage table AND emits one
  ::warning:: annotation per skipped combo — a not-run combination is visible at
  a glance (yellow, on the run summary) and cannot be mistaken for a pass.

GHA still cannot paint a per-matrix-leg job grey, but this sidesteps that
entirely: untestable combos are simply not test legs. Nothing silently green,
nothing silently vanished.

- Append `|| true` to the require.php constraint pipeline: under set -o pipefail
  a no-match grep would terminate the script and bypass the empty-check
  diagnostic below it.
- Replace `$(echo "$php" | tr -d '.')` with bash parameter expansion
  `${php//./}` — no subshell.

Subject: [PATCH 005/885] ci(TWO-24998): classify once via --emit-all; document
 degraded-probe trade-off
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Review follow-ups from #237 (all non-blocking, approval stands):

- Add `--emit-all`: one classification emitting {matrix, skips, php_lint} in a
  single object. The discover step now calls the classifier ONCE and jq-slices,
  instead of three independent runs that each re-fetch upstream + re-probe every
  docker image. Makes the three lists mutually consistent (no transient
  manifest-probe blip landing a combo in one list but not its mirror) and cuts
  upstream + Docker Hub rate-limit exposure 3x. (brtkwr note 1)
- Document the probe_image fail-toward-run trade-off in its header: under a
  degraded/rate-limited registry a genuinely-missing image classifies `run` and
  shows as a RED leg, not a yellow skip — loud red over silent green, by design,
  and the ::warning:: makes it greppable. (brtkwr note 2)

grep-under-pipefail (Gemini) already guarded with `|| true` at the constraint
parse. Individual --emit-* modes retained for local use.

Subject: [PATCH 006/885] feat: source payment terms, surcharge cap and default
 term from the merchant API
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

TWO-24814 / TWO-24952 / TWO-24859

The offerable payment terms, the buyer-surcharge cap and the merchant's
default term are per-merchant commercial values — they vary between
merchants of the same brand — so GET /v1/merchant is their authoritative
source, not brand.xml. Mirrors the minimum-order-value pattern already
in place.

- Add Service/Merchant/RecordProvider: one verify_api_key -> GET
  /v1/merchant fetch, cached + memoised per API key. Single source of the
  merchant record for every consumer.
- Add Service/Merchant/SettingsProvider: getAvailableTerms (available_terms),
  getSurchargeLimit (surcharge_limit), getDefaultTerm (due_in_days).
- MinimumOrderProvider now consumes RecordProvider (parsing only); the
  fetch/cache protocol moved into the shared provider.
- Admin payment-terms + surcharge-grid blocks and the AvailablePaymentTerms
  source model read the offerable terms and surcharge cap from the merchant
  API; the admin still narrows the buyer-facing term set.
- getDefaultPaymentTerm prefers the merchant's due_in_days when it is an
  offered term, else the existing admin/lowest fallback. SettingsProvider is
  injected into ConfigRepository via a \Proxy to break the construction cycle.
- Remove the now-unused getAvailablePaymentTerms / getSurchargeFixedMax from
  BrandRegistryInterface and its implementors, the Descriptor fields/getters,
  the Loader parse, and <available_payment_terms> from the vanilla brand.xml.
  brand.xsd keeps the elements optional for the transition.

Subject: [PATCH 007/885] fix(TWO-24952): RecordProvider caches only successful
 merchant reads
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Bharat review notes 1+2. Two related fixes to the merchant-record
fetch/cache:

- fetchRecord now treats an error payload (Adapter::execute returns a
  dict carrying error_code / http_status on failure) as "no record" and
  resolves to null, instead of caching the error dict as the merchant
  record — honouring the docblock's stated null-on-failure contract.
- getRecord persists only a successful record to the cross-request
  cache; a failure is memoised per request but NOT cached, so the next
  page view retries rather than serving a 900s-stale "no record". The
  first read during an outage can't be protected, but recovery no longer
  waits out the cache lifetime.

Trade-off: a sustained API outage now costs verify+fetch per page view
instead of one cached miss — accepted, outages are rare/short and admin
page-view volume is low, and fast recovery is worth more.

Subject: [PATCH 008/885] fix(TWO-24859): API default term seeds the field,
 never overrides admin
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Bharat review note 3: the merchant API's due_in_days took precedence
over an admin-configured default term at runtime, silently overriding an
explicit admin choice.

Invert the relationship so the API provides the *default* only, never an
override:

- getDefaultPaymentTerm now returns the admin-configured value when it is
  an offered term, else falls back to due_in_days when offered, else the
  lowest available term (single-available-term preselect preserved).
- Removed the static config.xml default_payment_term so an empty stored
  value genuinely means "admin never chose" — otherwise the hardcoded 30
  masked every unset install as an explicit choice.
- New DefaultPaymentTerm frontend_model pre-selects due_in_days in the
  admin field when unset (mirrors PaymentTermsCheckboxes' prepopulate),
  so a fresh install shows — and the checkout uses — the same term, while
  a later admin edit is stored and wins.

Note: the admin-field rendering can't be exercised in unit tests (needs
the Magento admin form); the resolver precedence is fully covered.

Subject: [PATCH 009/885] =?UTF-8?q?ci(TWO-25005):=20add=20upgrade-smoke=20?=
 =?UTF-8?q?=E2=80=94=20prev-major=20(1.x)=20=E2=86=92=20HEAD=20vanilla=20m?=

MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8

magento-plugin had no upgrade coverage (phpstan + di-compile only). Add an
upgrade-smoke that installs the latest previous-major release (currently 1.16.2)
then composer-requires this branch's HEAD and re-runs di:compile — proving the
cross-major 1.x -> 2.x vanilla merchant upgrade lands cleanly on every PR.

two-inc/magento2 keeps the same package name across majors (no rename/split like
the ABN overlay, TWO-25001), so this is a clean same-package upgrade and the
right home for real 1.x -> 2.0 coverage. Mirrors the abn job shape: discover
prev-major tag (skip visibly if none), install prior via path repo, rmdir
force-clear before module:enable (TWO-25003), re-point the repo at HEAD, verify
Two_Gateway enabled + version moved off the prior tag.

Subject: [PATCH 010/885] ci(TWO-25005): run setup:upgrade in both
 upgrade-smoke legs
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Bharat review: the job installed the prior release and HEAD and ran
di:compile on each, but never setup:upgrade — so the cross-major DB
schema/data patches and the setup_module.schema_version 1.x->HEAD
transition (the surface an upgrade-smoke exists to protect) were never
exercised. As written it was close to a fresh-HEAD install + di:compile,
which the di-compile job already covers.

Add setup:upgrade to both legs: the prior leg to establish the 1.x
schema_version FROM state, the HEAD leg to run the actual cross-major
migration.

Subject: [PATCH 011/885] ci(TWO-25005): address upgrade-smoke review nits

- resolve prior tag via `git ls-remote --tags` not the GitHub tags API:
  no token, no per_page=100 cap, and a transport error now FAILS the step
  instead of skip-greening on empty JSON (Bharat nits 1+2)
- fail loud if `composer show` can't report the post-upgrade version
  instead of `|| echo unknown`, which sailed past the version guard (nit 3)
- drop the superstitious `sleep 10`; the image ships a pre-installed
  Magento and the sibling di-compile job execs with no wait (nit 4)

Subject: [PATCH 012/885] fix(ABN-460): re-evaluate payment visibility when
 checkout totals change
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The minimum-order gate hides the payment method server-side via
Model\Two::isAvailable, comparing the quote grand total (net/gross)
against the funding-partner and merchant minimums. That check is
correct, but Luma's payment-service caches the method list from the
last shipping-information/payment-information fetch and does not
re-filter it when the totals move afterward — a shipping-method switch
or a coupon applied on the payment step. So a basket crossing the
threshold keeps its stale visibility until a full checkout reload.
Hyva and FireCheckout re-fetch on every totals change and are fine;
this gives Luma (and Luma-derived one-step checkouts) the same.

Add a headless checkout component, mounted under the always-present
sidebar (not the payment renderer, which is absent while the method is
hidden), that subscribes to quote.getTotals() and re-runs server-side
availability via get-payment-information on a genuine grand-total
change. The server gate stays the sole source of truth — the minimum
logic is never duplicated in JS. Guards dedup no-op re-emits and
prevent the refresh loop the action's own setTotals() would cause.

Jest coverage for the dedup/loop/re-entrancy/baseline logic.

Subject: [PATCH 013/885] fix(ABN-460): trailing-edge refresh for mid-flight
 totals changes

Address Gemini review: a genuine totals change arriving while a refresh
is in flight was swallowed, which could leave availability decided
against a superseded total (switch shipping, then apply a coupon before
the first refresh resolves). Park the latest such value and re-run once
the in-flight call resolves; multiple mid-flight changes coalesce to the
latest. Move the no-op-equality check ahead of the in-flight guard so
the self-triggered setTotals re-emit never enters the pending queue, and
guard the action call so a synchronous throw can't strand _refreshing.

Subject: [PATCH 014/885] fix(e2e): settle shipping recalc before reading
 totals in selectShipping

min-order.spec's precondition (flatTotal > freeTotal) failed on CI: selectShipping's waitIdle only clears the loading-mask, but Magento recalculates totals a beat later via a knockout observable, so grandTotal() could read the stale pre-recalc value and flat came back equal to free. Poll until shipping_amount reflects the chosen rate (non-zero for flat, zero for free) before returning; guard totals() being null mid-recalc. Verified live on the GBP staging store: flat grand=50 (shipping 5), free grand=45.

Subject: [PATCH 015/885] fix(e2e): manage Use-Default checkbox in min-order
 config write/teardown
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The gate spec's writeMinimumConfig called fill()/selectOption() directly,
but a Magento config field renders disabled while its "Use Default"
checkbox is checked — so the teardown restore timed out (8s) waiting for
an editable, disabled input (observed: the merchant_minimum_order field
came back disabled="disabled" with an empty value on restore).

Drive the field's _inherit checkbox first: to set a custom value, uncheck
it and wait for the field to be editable before filling; to restore a
field that was on its default, re-check it rather than typing an empty
string into a disabled input. readMinimumConfig now also captures each
field's inherit state so teardown restores exactly as found.

MIME-Version: 1.0

Playwright's setChecked() timed out (8s) on Magento's config-inherit
checkbox. Drive it with a native in-page click instead — the same
technique selectShipping uses for the styled radio — which flips the box
and fires the onclick handler that enables/disables the paired field.
Toggle only when the current state differs from desired.

 before editing
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

fill() on the minimum field timed out even after the input was enabled:
the field sits in the collapsible "payment_method" group, which a section
landing can leave collapsed, so the input is in the DOM but not visible
(toBeEditable passes, fill's visibility check hangs). Force the group
open (idempotent — only click the header when the field isn't already
visible) before reading or writing the config.

Subject: [PATCH 018/885] fix(TWO-25020): resolve version-panel commit SHA from
 the Composer registry
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The admin Version panel showed the commit column as — on staging. Root
cause: the module is now composer-installed under vendor/ (Packagist/dist
distribution), which has no .git worktree, so extractCommit()'s
.git/worktree path regexes found nothing.

Prefer Composer's installed registry, which records the exact source/dist
reference (verified on the pod: InstalledVersions::getReference(
'two-inc/magento2') === the deployed commit). Read the package name from
composer.json (module dir or one level up, mirroring readComposerVersion),
look up its reference, and use it when it's a hex SHA; otherwise fall back
to the existing .git/worktree parse (git-sync / dev checkouts). A non-hex
reference (path/branch install) is rejected so it can't render as a commit.

The static registry call is isolated behind a composerReference() seam for
unit testing. New VersionTest covers: composer ref wins, hex validation,
git-worktree fallback, monorepo parent-dir composer.json, empty when
neither signal is present.

- *  - and crucially it must NOT loop, because get-payment-information itself

- * Re-evaluates payment-method availability when the quote totals change.
- *
- * The payment method's availability (Model\Two::isAvailable) depends on
- * the order value via the minimum-order gate, which compares the quote
- * grand total (net or gross) against the funding-partner / merchant
- * minimum. That check is server-side and correct — but Luma's
- * payment-service caches the method list from the last
- * set-shipping-information / payment-information fetch and does NOT
- * re-filter it when the totals move afterward (a later shipping-method
- * switch, a coupon applied on the payment step). So a basket that crosses
- * the minimum after the payment step is reached keeps its stale
- * visibility until a full checkout reload. Hyvä and FireCheckout re-fetch
- * on every totals change and are unaffected; this component gives Luma
- * (and Luma-derived one-step checkouts) the same behaviour.
- *
- * The fix re-ASKS the server rather than re-deciding in JS: on a genuine
- * totals change it calls get-payment-information, which re-runs
- * isAvailable server-side and repopulates the payment-method list. The
- * minimum-order logic (currency conversion, net/gross basis,
- * platform-vs-merchant floor) stays in one place — the server gate — and
- * is never duplicated here, so the client cannot drift from what the
- * Two API enforces at order creation.
- *
- * Mounted from checkout_index_index.xml under the always-present sidebar,
- * NOT under the Two payment renderer: when the method is hidden
- * (below-minimum) its renderer is not instantiated, so a refresher living
- * there could never bring the method back once it becomes eligible.

The reactive show/hide it asserts depends on the payment-availability

Subject: [PATCH 022/885] feat(ABN-460): reactive payment availability via
 methods-only refresh
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Rebuild of the reverted reactive show/hide. A headless sidebar component
subscribes to quote.getTotals() and, on a genuine grand-total change,
re-fetches the payment-information endpoint and applies ONLY the returned
method list. The server re-runs isAvailable, so the Two method appears
and disappears in both directions as the basket crosses the minimum —
without a reload, matching Hyva/Fire.

Unlike the reverted attempt (which called the shared get-payment-information
action), this deliberately does NOT call quote.setTotals(): that action
stamps the server's possibly-pre-shipping totals over the correctly-
collected client totals, which mis-rendered the order total until a payment
method was selected. Skipping setTotals also means the refresh can't re-emit
the totals observable, so there is no loop to guard against beyond the
no-op-total dedup. Server isAvailable + place-order + API enforcement remain
the sole source of truth; no minimum logic is duplicated in JS.

Jest covers: no fetch on bootstrap/no-op re-emit, fetch on real change,
setTotals never called, baseline seeding, trailing-edge coalescing, error
path. min-order e2e stays skipped until this is verified on the deployed
dev shop (see PR notes).

+/**
+ * Re-evaluates payment-method availability when the quote totals change.
+ *
+ * Whether the Two method is offered depends on the order value via the
+ * server-side minimum-order gate (Model\Two::isAvailable). On Luma the
+ * payment-service caches the method list from the last
+ * set-shipping-information / payment-information fetch and never re-filters
+ * it when totals move afterwards (a later shipping-method switch, a coupon
+ * applied on the payment step), so a basket crossing the threshold keeps its
+ * stale visibility until a full checkout reload. Hyvä and FireCheckout
+ * re-fetch on every totals change and are unaffected; this gives Luma (and
+ * Luma-derived one-step checkouts) the same behaviour.
+ *
+ * On a genuine grand-total change it re-fetches the payment-information
+ * endpoint and applies ONLY the returned method list — the server re-runs
+ * isAvailable, so the method appears/disappears in both directions. It
+ * deliberately does NOT call quote.setTotals(): the shared core action
+ * (get-payment-information) does, which stamps the server's (possibly
+ * pre-shipping) totals over the correctly-collected client totals — the
+ * regression that got the first attempt reverted. Skipping setTotals also
+ * means this can't re-emit the totals observable, so there is no refresh
+ * loop to guard against beyond the no-op dedup.
+ *
+ * Mounted from checkout_index_index.xml under the always-present sidebar,
+ * NOT under the Two payment renderer: when the method is hidden its renderer
+ * is not instantiated, so a refresher living there could never bring it back.

Subject: [PATCH 023/885] =?UTF-8?q?fix(ABN-460):=20address=20adversarial?=
 =?UTF-8?q?=20review=20=E2=80=94=20apply-on-set-change,=20silent=20fail,?=
 =?UTF-8?q?=20tax=20key,=20dispose?=
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Adversarial review (Yoda/Han/Vader) findings:
- BLOCKER (Vader): setPaymentMethods on every totals tick swaps the observable
  with fresh refs → Luma's list.js rebuilds EVERY renderer, wiping a half-filled
  Two form + selection when the buyer applies a coupon / store credit while Two
  stays available. Now apply the list ONLY when the available-method code set
  actually changes (add/remove Two across the minimum), never on unchanged sets.
- BUG (Han + Vader): a failed probe surfaced the checkout error banner and
  advanced the dedup key, stranding a stale list with no retry. Now fails
  silently (dropped the errorProcessor/messageList deps) and rolls the key back
  so the next totals emit retries.
- BUG (Han + Vader + Yoda): dedup keyed on grand_total only missed a net-basis
  tax-only flip. Key on grand_total + tax_amount.
- NIT (Han + Yoda): totals subscription never disposed. Added destroy() teardown.

Stale-server race (Han) and shipping-step over-fetch (Vader) are defused by the
apply-on-set-change guard (an unchanged/stale list is simply not applied).

Tests +6: set-change apply vs skip, net-basis tax key, logged-in URL, guest URL,
silent-fail rollback/retry, destroy disposes the subscription. 42 green.

Subject: [PATCH 024/885] feat(ABN-460): client-side min-order visibility gate
 + always-list on Amasty
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Fixes the min-order show/hide on Amasty OneStepCheckout, which the server-side
gate + #245 can't handle: Amasty persists the shipping method to the server
quote only at place-order, so isAvailable judges a stale (shipping-blind) total
— a dearer shipping that crosses the minimum never registers server-side (case
1), and a stale-high persisted shipping leaves the method listed after the buyer
switches down (case 2).

Two parts:
- Model\Two::isAvailable — when Amasty OSC is enabled for the quote's store
  (amasty_checkout/general/enabled, STORE scope so it tracks the active store
  view), offer the method unconditionally and defer visibility to the client.
  Every other checkout keeps the authoritative server gate unchanged. Absent
  module → flag false → no change.
- Client-side visibility gate — ConfigProvider exposes the server-resolved
  minimum(s) {amount, basis} in the display currency (getDisplayMinimums; server
  does rule-resolution + FX). The renderer hides the method below the live total
  (universal case-2 safety net; on Amasty also drives showing above it) via a
  pure `minimum-order-visibility` helper + a `visible` binding.

Display-only: server isAvailable + place-order + the Two API remain the
enforcers, so a below-min order still can't complete.

Jest: minimum-order-visibility helper (net/gross basis, multi-min, boundary,
missing data); amd-harness registers the new dep. 49 green. PHP structural
changes covered by CI (phpstan/di-compile/phpunit); behaviour to be
browser-verified across all four checkouts on the dev shop.

Subject: [PATCH 025/885] refactor(ABN-460): extract shared
 buildMerchantMinimum helper
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

isAvailable() and getDisplayMinimums() both constructed the merchant
minimum-order tuple inline from the same admin config. The two MUST
agree — the client-side visibility gate's whole premise is that what
the server enforces equals what the client displays — so the drift
risk of two copies is a correctness hazard. Extract a single private
buildMerchantMinimum(Quote, ?platform) both call.

Subject: [PATCH 026/885] fix(ABN-460): server backstop, scoped Amasty bypass,
 fail-closed client gate

Adversarial review (SRE + QA lenses) surfaced that the always-list-on-
Amasty approach had weaker guarantees than its comments claimed. Fixes:

- authorize() minimum backstop (F1): re-check the FINALISED order total
  (shipping is persisted by placement, so the server is no longer blind)
  against BOTH platform and merchant minimums, fail-closed. This is the
  real server enforcer on Amasty, where isAvailable() is bypassed, and it
  covers the merchant minimum the Two API never receives. A normal buyer
  never hits it (client gate); it stops JS-disabled / direct-API / total-
  dropped-after-select paths.
- Scope the Amasty bypass to a deliberate admin override (F2): reading
  amasty_checkout/general/enabled via ScopeConfig alone was unsafe -
  Amasty ships enabled=1 in config.xml, so the flag reads true by
  inheritance on store views where no admin configured it, leaking the
  bypass onto Luma/Hyva/Fire. Now require an explicit core_config_data
  override in the store's scope chain, not the packaged default.
- Fail-closed client gate on unresolvable FX (F3): getMinimumOrderVisibility
  now signals minimumOrderUnresolved when an active minimum can't be
  projected into the display currency; the renderer hides rather than
  showing for want of a number, mirroring MinimumOrderGate.
- Deselect Two when hidden (F4): hiding the radio isn't enough on Amasty,
  whose global place-order button sits outside this renderer; deselect so
  a hidden method can't be submitted (authorize() is the server backstop).
- pureComputed + dispose() teardown for the visibility gate (F5).
- Treat {}/absent grand_total as data-not-ready, not zero (QA nit) + tests.
- Correct the isAvailable/renderer comments to state the true enforcement
  model instead of an overstated 'API enforces' claim.

Subject: [PATCH 027/885] fix(ABN-460): thread new CollectionFactory arg
 through GenericPaymentMethod

The buildMerchantMinimum/Amasty-detection work added a
ConfigDataCollectionFactory constructor arg to Two mid-signature;
GenericPaymentMethod redeclares the parent constructor and passes args
positionally, so setup:di:compile rejected it (Incompatible argument
type: CollectionFactory vs AbstractResource). Add the arg in the same
position and pass it through.

Subject: [PATCH 028/885] fix(ABN-460): backstop fails closed on unresolvable
 FX (round-2 review)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Round-2 verification (convergent SRE+QA finding): assertOrderMeetsMinimum
delegated to MinimumOrderGate::isBelowMinimum, which is fail-SOFT — on a
cross-currency order with no configured FX rate it returns 'not below' and
allowed placement. That contradicts the backstop's fail-closed contract and,
since it is the SOLE server enforcer of the merchant minimum on Amasty, let a
below-merchant-minimum order through on the exact path (Amasty + JS bypass)
the backstop exists to catch. Now project the minimum into the order currency
via getMinimumForDisplay (the same projection the client-display gate uses)
and reject when it cannot be projected — fail closed, enforce == display.

Also from round 2:
- getMinimumOrderVisibility: empty display currency on a real quote now
  returns unresolved=true (client hides), matching the server gate's
  fail-closed stance instead of failing open.
- Correct the pureComputed comment: the deselect subscription keeps it awake,
  so teardown relies on dispose(), not auto-sleep.
- Fix stale getDisplayMinimums reference in the helper JSDoc.

Subject: [PATCH 029/885] feat(TWO-25072): surcharge tax via Magento tax rules
 engine

Add an optional Surcharge Tax Class (Product Tax Class dropdown,
mirroring core's tax/classes/shipping_tax_class) and, when selected,
resolve surcharge tax through TaxCalculationInterface::calculateTax()
using the shipping-tax pattern (QuoteDetailsItem + TYPE_ID
TaxClassKey + quote address/customer context). This makes surcharge
tax destination-aware, rule-driven, and natively additive for
multi-rate jurisdictions (US state+local, CA GST+PST), and zero when
no Tax Rule matches.

The legacy flat Surcharge Tax Rate remains the default and the
explicit opt-out (empty-value option in the new dropdown), so
existing merchants are never silently migrated. A data patch
provisions a rule-free 'Payment Terms Surcharge - No Tax' Product
Tax Class for a guaranteed-untaxed surcharge; the calculator logs an
error (without failing checkout) if that class ever resolves real
tax or if the configured class has been deleted.

ComposeOrder is unchanged: it keeps forwarding the collector's
two_surcharge_tax_amount / tax_rate order columns (session fallback)
into the BUYER_FEE line item.

Subject: [PATCH 030/885] fix(TWO-25072): surcharge tax engine review-round-1
 fixes
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Adversarial review findings on the tax rules engine integration:

- BLOCKER: check configured tax class existence unconditionally, not
  only when tax resolved non-zero. Deleting a Product Tax Class
  cascades its Tax Calculation rules away, so the deleted-class case
  resolves to zero tax and previously skipped the check entirely —
  merchant silently stopped collecting surcharge tax with no log
  signal. Now logs a clear "no longer exists" error regardless of the
  resolved amount.
- Throw LocalizedException when an engine pass returns no item for
  the surcharge code (e.g. third-party TaxCalculationInterface
  override dropping unknown item types) instead of returning a
  valid-looking zero. Each currency pass (quote/base) is checked
  independently, so a mismatched pair can never produce an order with
  inconsistent tax_amount / base_tax_amount.
- Pass round=true to both calculateTax() calls, matching core's
  Tax::getQuoteTaxDetails() invocations (docstring previously claimed
  an exact core mirror while passing false); comment now states the
  6dp rounding is only a wire-contract cap.
- SurchargeNoTaxClass patch: on name collision with a pre-existing
  Product Tax Class, probe tax_calculation for attached Tax Rules and
  log a loud error instead of silently treating a rule-bearing class
  as the guaranteed-untaxed class. Rule-free collision (idempotent
  re-run) stays silent; no duplicate class is ever inserted.

Tests: 250 passing (241 baseline + 9 new covering each fix).

Subject: [PATCH 031/885] fix(TWO-25072): guard null shipping on assignment for
 virtual-only quotes

ShippingAssignmentInterface::getShipping() can return null (e.g. a
virtual-item-only quote), which made buildQuoteDetails() fatal on
->getAddress(). Treat the shipping address as absent instead, routing
through mapAddress()'s existing null-address path.

Subject: [PATCH 032/885] fix: run setup:di:compile before deploy:mode:set
 developer

di:compile resets Magento to production mode as a side effect, so
running deploy:mode:set developer before it meant the mode got
silently reverted to production right after install. Swap the
order so developer mode is set last and actually sticks.

Same bug was previously fixed in magento-abn-plugin (66062d8) but
was reintroduced here by a later Makefile/install script refactor.

Subject: [PATCH 034/885] feat(config): never auto-default surcharge tax
 treatment; deprecate flat rate as Custom

Unified cross-platform rule (WooCommerce/PrestaShop/Magento): the
surcharge tax treatment selector never auto-defaults.

- Selector starts unselected with an explicit placeholder
  ("-- Select surcharge tax treatment --"); no value is ever seeded
  from tax/classes/default_product_tax_class.
- New backend model rejects the config save (server-side, not just
  admin JS) while a surcharge method is enabled and no treatment is
  selected. Sibling paths derived from the field's own path, so
  synthesized brand forms (payment/<brand_code>/) get identical
  enforcement.
- Legacy flat-rate field renamed at the CODE level only:
  getSurchargeTaxRate -> getCustomSurchargeTaxRate, field id/label ->
  custom_surcharge_tax_rate, block -> CustomSurchargeTaxRate. The
  persisted core_config_data path stays surcharge_tax_rate (no data
  migration). Marked deprecated throughout: initial attempt at tax
  support, superseded by the tax-rule-based selector, retained only
  for pre-existing merchants.
- "Custom flat rate (deprecated)" option appears in the selector only
  when a legacy rate value genuinely exists (null/'' existence check,
  never truthy - a configured 0 still counts). Backend model refuses
  "custom" without a pre-existing rate, so no new merchant can create
  one. Runtime maps ''/custom/non-numeric to the flat-rate path and
  never int-casts them to tax class 0 ("None").
- brand_form_template.xml gains the surcharge_tax_class field it was
  missing since PR #248 (template is a documented clone of system.xml).
- Admin JS visibility list now toggles surcharge_tax_class; the
  deprecated rate row is owned by the system.xml <depends> (custom
  only).
- i18n (nb/sv/nl) updated for renamed/new strings; unit tests for the
  backend model, source model gating and repository mapping (272 green).

Subject: [PATCH 035/885] fix(config): use scope_id for sibling reads; hide
 deprecated rate when surcharges off

Review round 1 (Gemini):
- getScopeCode -> getScopeId in the tax-treatment backend model: CLI
  config:set (PreparedValueFactory) sets scope/scope_id but never
  scope_code, so scope_code-based sibling reads would silently resolve
  the wrong scope under CLI saves. ScopeConfigInterface::getValue
  resolves numeric ids fine.
- custom_surcharge_tax_rate <depends> now also requires an enabled
  surcharge method, so the deprecated row cannot linger visible when
  surcharge_type is switched to none while treatment is "custom".

Subject: [PATCH 036/885] fix(TWO-24775): fail open on merchant minimum FX,
 keep platform floor closed

MinimumOrderGate::isSatisfied applied the same fail-closed policy to
both the platform floor (funding-partner requirement) and the
merchant's own extra minimum (local admin config) when FX conversion
was unconvertible. Only the platform floor should block checkout in
that case; the merchant's own bar now fails open, matching PrestaShop
and WooCommerce behavior on this gate.

Subject: [PATCH 037/885] fix(TWO-24775): apply split fail policy to client
 visibility gate; guard non-finite FX rates
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The client-side visibility gate (getMinimumOrderVisibility, the actual
selection gate on Amasty checkouts) still failed closed uniformly: an
unprojectable merchant minimum hid the whole method. Now only an
unprojectable PLATFORM floor sets `unresolved`; an unprojectable
merchant minimum is omitted from `minimums` (fail-open), matching the
server gate's policy.

Also guard satisfiesMinimum() against non-finite rates: NAN <= 0 is
false in PHP, so a NaN rate fell through to an always-false comparison
— blocking on the merchant minimum instead of failing open.

Review nits: drop dead default on satisfiesMinimum's fail-mode param,
named args at call sites, align param naming, rename unconvertible()
to handleUnconvertible(), dedupe policy rationale into the class
docblock, tighten isSatisfied() @return doc.

Subject: [PATCH 038/885] fix(TWO-24775): fail open on merchant minimum FX in
 placement backstop

assertOrderMeetsMinimum() applied fail-closed uniformly: an unprojectable
(missing FX rate) minimum of EITHER kind rejected the order. Split it to
match the gate and client-display policy elsewhere in this PR: platform
floor unprojectable still rejects (fail closed), merchant minimum
unprojectable is skipped and placement proceeds (fail open). A
projectable-but-unmet minimum still rejects for both.

Subject: [PATCH 039/885] fix(TWO-24775): guard non-finite FX in display
 projection; drop blanket hide on empty display currency
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

getMinimumForDisplay() now sits on the enforcement paths (client
visibility gate and placement backstop) but kept the pre-round-1 rate
guard: a NaN rate fails NAN <= 0 and leaked ['amount' => NAN] to
callers, so the backstop's below-minimum comparison was always false
and silently admitted orders the platform floor could not verify. Add
the is_finite() guard and route the unconvertible branch through
handleUnconvertible() so fail-closed events land in the monitored
error log (fail-open at debug), with the existing per-pair dedup.
Callers pass failClosedOnUnconvertible per minimum, matching
isSatisfied()'s split.

getMinimumOrderVisibility()'s empty-display-currency early return set
unresolved (hiding the method) even with no platform floor active — a
split-policy violation. Drop it and let the empty currency flow into
the per-minimum projections, exactly like assertOrderMeetsMinimum():
platform floor still fails closed, a merchant minimum alone fails open.

Subject: [PATCH 040/885] fix: TWO-24868 remove orphaned two_telephone
 customer_address attribute
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The two_telephone EAV attribute added by the InternationalTelephone
data patch is orphaned — nothing reads or writes it. Add a new
RemoveInternationalTelephone data patch (depends on the original
patch) that removes it; the shipped patch's logic is untouched.

Subject: [PATCH 041/885] TWO-25099/fix: fail loud on negative discount amounts
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Guard getDiscountAmountItem() and getDiscountAmountShipping() so a
negative discount from an upstream cart-rule bug logs a diagnostic and
throws instead of silently reaching the Two API. Mirrors the PrestaShop
guard shipped in TWO-24741.

The sign check runs on the native-precision float and evaluates
negativity at the 2dp payload boundary (round once): sub-cent binary
float residue (e.g. 0.3 - (0.1 + 0.2)) is not a data error and must not
false-positive the guard — the phantom-negative trap PrestaShop hit.
The returned value stays unrounded; roundAmt() at payload assembly
remains the single rounding point.

Subject: [PATCH 042/885] feat: TWO-24809 drive sole-trader and company-type
 gates from registry endpoint

Replace the two hardcoded country lists with the live answer from
GET /registry/v1/supported-company-types/{ISO}, mirroring the
WooCommerce/PrestaShop fetch+cache+fail-soft pattern:

- new Service/Api/SupportedCompanyTypes: server-side call with the
  merchant API key, CacheInterface TTL 3600s keyed by country,
  fail-soft to [] on any error without caching the failure
- new anonymous webapi GET /V1/two/supported-company-types/:countryCode
  so the renderer can re-query as the buyer edits the billing country
- ConfigProvider seeds the quote's billing-country answer into
  checkoutConfig (supportedCompanyTypes) and drops the consumer-less
  supportedCountryCodes list
- gateway_method.js gates the Business/Sole trader mode tab on the
  registry answer (per-country memo, stale-answer guard) instead of
  the hardcoded ['gb']

Subject: [PATCH 044/885] feat: TWO-25103 source FX rates from
 /refdata/v1/fx-rates

Swap CurrencyRatesProvider off Magento's Directory rate table onto
Two's EUR-pivot spot-rate endpoint, so plugin conversions (surcharge,
min-order, admin config) use the same rates Two applies server-side.

- Service/Fx/RateTableProvider owns fetch+cache: full table cached
  with no expiry (last-known-good), 6h staleness window, opportunistic
  read-path refresh with a 5-minute failure cooldown so an API outage
  never adds a fetch round-trip per page view.
- Cron two_gateway_refresh_fx_rates refreshes every 6h, once per
  distinct store-scoped API key.
- CurrencyRatesProviderInterface unchanged (callers untouched); null
  now only means never-fetched or unsupported currency.
- Native Directory-rate path retired; drop the Currency::load phpstan
  suppression it existed for.

 /**
  * Service contract for currency exchange rate lookups.
  *
- * Magento ships no read-side service contract for currency rate lookups — its
- * rate data is only reachable via the legacy Currency active-record model
- * (Magento\Directory\Model\Currency::load). This interface wraps that access
- * so callers see a clean contract, and the one internal implementation is
- * the single place where the phpstan "service contracts" rule is suppressed.
+ * Rates are sourced from Two's EUR-pivot spot-rate table
+ * (GET /refdata/v1/fx-rates), cached with a 6h background refresh and a
+ * last-known-good fallback, so conversions use the same rates Two applies
+ * server-side. Callers depend on this contract; the fetch/cache protocol
+ * lives behind the single implementation.

+     * worth `rate` units of $toCurrency.
      *
-     * Rates are always computed through base:
-     * - from == to           → 1.0

Subject: [PATCH 045/885] fix: TWO-25103 merchant minimum bar fails open on
 unresolvable rate
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Per the TWO-25103 fail-semantics spec (latent posture bug flagged in
TWO-24739): the platform floor keeps failing closed — never offer an
order we cannot prove meets the funding partner's minimum — but the
merchant's own bar now fails open, so a merchant preference cannot
hide the payment method when a rate is unavailable.

Subject: [PATCH 046/885] fix: TWO-25103 address review findings on FX cutover
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

- Forward the store scope through SurchargeCalculator::convertAmount to
  getRate — FX rates are fetched with the store-scoped API key, and
  dropping the id broke multi-store installs with per-store keys.
- Guard cached rate-table reads: corrupt or wrong-shaped cache entries
  degrade to a refetch instead of throwing on the isAvailable() hot path.
- Retire admin-facing remediation text pointing at Stores > Currency
  Rates (the Directory table no longer feeds conversions), with i18n.

Subject: [PATCH 047/885] feat(TWO-24758): self-invoice PDF upload gated on
 invoice_distributed_by_merchant
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Magento can render+upload the invoice in-process (native
Magento\Sales\Model\Order\Pdf\Invoice + already-injected InvoiceService),
mirroring the shipped PrestaShop TwoInvoiceUploadService pattern via
checkout-api's 3-step signed-URL flow. Gate is flag-only per TWO-25106
(Option A) — no admin toggle.

- Service/Merchant/SettingsProvider::isInvoiceDistributedByMerchant()
  reads the flag from the cached GET /v1/merchant record; absent/
  unresolvable degrades to false.
- Service/Invoice/UploadService: queueForOrder() is the cheap gate+DB
  write called synchronously from the fulfilment observer; upload()
  does the actual render + 3-step upload (signed URL, GCS PUT with
  retry-on-5xx/no-retry-on-4xx, status poll) and persists one of
  NOT_APPLICABLE/UPLOADING/UPLOADED/FAILED with an order history
  comment on completion.
- Cron/ProcessInvoiceUploads runs the network-bound upload() out of
  band every minute, so the observer never blocks on I/O.
- New sales_order columns: two_invoice_id, two_invoice_upload_status,
  two_invoice_upload_reference, two_invoice_uploaded_at,
  two_invoice_upload_error.

Observer/SalesOrderShipmentAfter.php only reaches this on whole-order
shipment (same guard as native Magento invoice creation) and only for
merchants on the 'shipment' fulfilment trigger — 'complete'/'invoice'
triggers are out of scope for this ticket.

Assumption flagged for QA: the two_invoice_id is read from
fulfilled_order.invoice_details.id (falling back to invoice_details.id)
on the /fulfillments response, mirrored from PrestaShop's order-level
field of the same name since checkout-api serves both plugins from the
same backend. This repo has no local visibility into checkout-api's
actual /fulfillments response schema to confirm the field name/shape;
manual QA on a real order is the way to verify this before merge to
production traffic.

Subject: [PATCH 048/885] fix(TWO-24758): close concurrency and correctness
 gaps from adversarial review
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Self-review (Leia/Han/Yoda/Vader personas) on PR #257 converged on a
blocking concurrency gap plus several real bugs before merge:

- Cron/ProcessInvoiceUploads: claim each order via a non-blocking
  LockManagerInterface lock before upload(). A single order's
  worst-case latency across the 3 upload steps can exceed the
  1-minute schedule, and Magento's cron scheduler only guarantees
  single-execution of one schedule row, not job-code mutual exclusion
  across ticks/replicas — without a claim, two overlapping runs could
  race UploadService's read-modify-write on the same order row.
- UploadService::queueForOrder: treat an order already UPLOADING as a
  no-op (not just UPLOADED) — a double-fired shipment observer must
  not reset two_invoice_upload_reference/error while the cron is
  mid-flight for that order.
- UploadService::upload: re-check invoice_distributed_by_merchant at
  execution time, not just at queue time (the flag can flip between
  the observer queueing the order and the cron draining it minutes
  later).
- UploadService::renderInvoicePdf: select the invoice via
  getLastItem() (most recently created), not getFirstItem() — an
  order can already carry an earlier invoice unrelated to this
  fulfilment. Missing invoice now resolves to NOT_APPLICABLE (a
  legitimate case, e.g. zero-grand-total orders) instead of a
  spurious FAILED + history-comment noise.
- Thread $order->getStoreId() through both remaining Adapter::execute()
  calls in the upload flow — previously dropped to the default/global
  scope, which would authenticate as the wrong store's API key on any
  multi-store install.
- Align the http_status success/error check with the >=400 convention
  already used elsewhere in this codebase, rather than pinning to one
  literal status code Adapter::execute() doesn't actually guarantee.
- Observer/SalesOrderShipmentAfter: wrap the queueForOrder call in
  try/catch — by that point Two has already been told the order is
  fulfilled and the Magento invoice/shipment already succeeded, so a
  transient failure persisting the upload-queue status must not
  surface as a shipment-creation error. Also drops an unused
  SettingsProvider injection left over from an earlier draft (the gate
  check now lives entirely in UploadService).

Also: removed a dead, unreferenced SearchResultsInterface test stub
(Leia) and added a LockManagerInterface test stub.

Accepted as follow-up, not fixed here: a FAILED order is a terminal
dead end with no automatic retry path (Vader); flagged in the PR for
a follow-up ticket rather than building a retry system into this
change.

From a3c8829e4225e68c5d233d820987ba0cfad4ff58 Mon Sep 17 00:00:00 2001
From: Douglas Lindsay <dlindsay@two.inc>

Subject: [PATCH 049/885] fix(TWO-24758): harden round-1 fixes per round-2
 verification
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Round 2 verified the round-1 fixes (lock, TOCTOU recheck, storeId
threading) as real and correctly tested. Two smaller gaps remained:

- Observer/SalesOrderShipmentAfter: catch Throwable, not Exception,
  around queueForOrder() — matches the cron's own choice and the
  guarantee the comment already claims (a TypeError/Error must not
  surface as a shipment-creation failure either).
- Service/Invoice/UploadService::renderInvoicePdf: getLastItem() was
  "less wrong" than getFirstItem(), not actually guaranteed — it
  depends on the collection's default load order matching creation
  order. Now explicitly setOrder('entity_id', 'DESC') before taking
  getFirstItem(), so invoice selection doesn't rely on an implicit
  contract. Added a real regression test (two invoices, ids given in
  creation/ascending order) that would have failed against the old
  getLastItem()-on-insertion-order behaviour.

MIME-Version: 1.0

- Uppercase both sides of the currency pair in CurrencyRatesProvider::getRate
  so a lowercase/mixed-case caller resolves against the upper-cased rate
  table instead of silently missing it.
- Add the missing SurchargeCalculator exception translation key to
  nb_NO/nl_NL/sv_SE (only the sibling admin-warning string was updated).
- Correct RateTableProvider's cache docblock: "no expiry" means no TTL-based
  eviction, not immunity from cache:flush (part of this repo's standard
  deploy workflow) — the durability claim as written overstated the
  last-known-good guarantee.

Subject: [PATCH 051/885] fix(ABN-463): clear surcharge total when quote drops
 below min order

Surcharge::collect() only checked the quote's stored payment-method
code as its eligibility gate, decoupled from the min-order check
(MinimumOrderGate) that hides the payment method in checkout. A
shipping-method change can flip the payment method to ineligible
without ever deselecting it on the quote, so the surcharge kept
recomputing and reappearing in the order summary until the buyer
manually picked a different payment method.

collect() now re-runs the same min-order gate and clears the
surcharge whenever it fails, mirroring Two::isAvailable()'s check.

Subject: [PATCH 052/885] refactor(ABN-463): extract merchant-minimum
 resolution to shared service
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Self-review caught that the previous commit duplicated Two::buildMerchantMinimum()
verbatim into Surcharge.php — reintroducing the exact "two eligibility
gates can silently diverge" pattern this ticket exists to fix, just one
level down (the merchant-minimum calc instead of the isSatisfied() gate
itself). Two::buildMerchantMinimum()'s own docblock already called out
that this construction must live in exactly one place.

Extract MerchantMinimumResolver (parameterized by payment-method code,
since Surcharge is shared across brand overlays and isn't bound to a
single method instance's `_code`), inject it into both Two and
Surcharge, and delete both private copies.

Subject: [PATCH 053/885] fix(ABN-463): wire MerchantMinimumResolver through
 GenericPaymentMethod

GenericPaymentMethod extends Two and mirrors its constructor to inject
brand-overlay-specific code/brand args before delegating to
parent::__construct(). Missed updating it when Two's constructor
gained the new MerchantMinimumResolver dependency, which shifted the
positional args and broke DI compilation for every brand overlay.

Subject: [PATCH 055/885] TWO-24843/fix: recover the Luma Place Order button
 from a stale latch
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

On the Luma checkout the Place Order button could stay greyed for the rest of
the session, with every further click silently doing nothing, and a
refresh-then-retry reporting "The cart is locked for processing".

`isPlaceOrderActionAllowed` has only two writers. This renderer sets it false
before a place-order request and re-arms it in that request's `.always()`.
Core's `quote.billingAddress` subscription in
`Magento_Checkout/js/view/payment/default` sets it to `address !== null`, and
has no path back to true other than a further billing-address change — so a
transient null billing address, which is routine while the buyer edits an
address and around the renderer re-creation Luma performs whenever the
payment-method list refreshes after a shipping-method save, leaves the
observable false indefinitely. The observable is declared on the prototype, so
it is shared across every renderer instance and survives re-rendering, and the
template only greys the button with a CSS class rather than disabling it.
Clicks therefore kept arriving in `placeOrder()`, where the
`isPlaceOrderActionAllowed() === true` precondition dropped them without a
message.

Three changes:

- `placeOrder()` re-arms the observable when it is false and no place-order
  request of ours is in flight, tracked by a module-scope flag that pairs with
  the shared observable. The double-submit protection the latch exists to
  provide is preserved, and a click that really does arrive mid-request now
  says so instead of being swallowed.
- `placeOrder()` refuses a placement on a non-virtual quote with no shipping
  method. `QuoteValidator::validateBeforeSubmit` raises "The shipping method is
  missing" before any payment authorize, so such a request can only fail — but
  it still holds Magento's per-cart `CartMutex` lock and keeps the button
  latched for as long as it runs, which is how one mistimed click ended in
  "The cart is locked for processing" on the retry. Virtual quotes, which
  legitimately have no shipping method, are unaffected.
- `placeOrderBackend()` calls `getPlaceOrderDeferredObject()` inside a try and
  re-arms on a synchronous throw, which would otherwise leave the latch set
  with no `.always()` attached to ever clear it.

The one state this cannot rescue is a request that never settles at all,
because "hung" and "still working" are indistinguishable from the client and
guessing wrong duplicates an order. The shipping-method check removes the
trigger reported here from that path.

No server-side change: `CartMutex` releases its lock in a `finally`, the plugin
holds no lock state of its own, and `RestoreQuote` is correctly scoped to the
hosted-checkout return controllers — on an `authorize()` throw the `submitQuote`
transaction rolls back and there is nothing to restore.

Subject: [PATCH 056/885] TWO-25174/fix: four defects in the Luma payment
 renderer
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

All four live in view/frontend/web/js/view/payment/method-renderer/gateway_method.js.

1. placeOrder() required isPaymentTermsAccepted() unconditionally in its final
   conjunction, while the checkbox only renders under isPaymentTermsEnabled and
   nothing else ever writes the observable. With terms disabled the observable
   stayed false, placeOrderBackend() never ran and no error was shown — a
   silently dead button. Only ConfigProvider hardcoding the flag to true kept
   that unreachable. The conjunct is dropped; the isPaymentTermsEnabled-gated
   early return above it remains the single precondition.

2. showErrorMessage was defined twice in the same Component.extend literal, so
   the later, duration-less definition won and the duration/auto-dismiss variant
   was dead. The duplicate is removed, and validateEmails' only duration call
   site is corrected from 3 to 3000 milliseconds.

3. The in-flight guard keyed on isPlaceOrderActionAllowed rather than on
   placeOrderInFlight. That observable is prototype-shared and core's
   quote.billingAddress subscription can set it back to true mid-request, which
   let a second click through to a second order-create POST. It now keys on our
   own in-flight flag.

4. .always() was registered after .done(), so an afterPlaceOrder() throw
   stranded both the latch and the module flag — the one path TWO-24843's
   recovery cannot escape. .always() is now registered first; clearing before
   afterPlaceOrder() is safe because JS is single-threaded and no click can land
   in between.

Extends the TWO-24843 latch suite rather than adding a parallel file. Its
deferred stand-in now keeps callbacks in one registration-ordered list and lets
a throw abandon the rest, matching jQuery, so registration order is actually
under test. Added cover: placement succeeds with terms disabled and unaccepted
(plus the enabled-and-unaccepted control), two rapid clicks still yield exactly
one request, a second click is still refused when the shared latch is re-armed
mid-request, the latch clears when afterPlaceOrder() throws, and
showErrorMessage auto-dismisses with a duration but not without one.

Subject: [PATCH 057/885] TWO-25174/fix: render the invalid-email message once,
 not twice
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

validateEmails() displays invalidEmailListMessage itself (with a 3000ms
auto-dismiss) and returns false. placeOrder() then displayed the same
message a second time, without a duration, so a buyer with a malformed
forward-email address saw the error twice — one copy fading out and one
copy stuck on screen.

Drop the display from placeOrder(). The helper now owns both validation
and its own message, matching processTermsNotAcceptedErrorResponse()
immediately above it, where placeOrder() likewise only reacts to the
failure and returns. validateEmails() has no other call sites, so no
caller loses its message.

Covered by two new cases in the existing latch/renderer suite: a
rejected click renders exactly one message and that message is the
auto-dismissing one, and a valid list still places the order.

Subject: [PATCH 058/885] fix(checkout): hold invalid-email error for 15s not
 3s (TWO-25174)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The forward-email validation error auto-dismissed after 3000ms, which is
too short to read while still typing in the field; a permanent message is
too sticky once the address is corrected. Split the difference at 15000ms.

Only the validateEmails() dismissal changes — other showErrorMessage()
callers pass no duration and stay sticky by design.

Subject: [PATCH 059/885] refactor(config): remove dead days_on_invoice config
 key (TWO-24859)

Nothing read it. The three sites were the only references in the repo:
XML_PATH_DAYS_ON_INVOICE on Api\Config\RepositoryInterface (never used,
not even by the getter, which built its path inline), the interface's
getDueInDays() declaration plus its Repository implementation (no
callers), and a 14 default in etc/config.xml with no matching
system.xml field, so no merchant could ever set it.

Payment terms come from the merchant record (GET /v1/merchant), not from
store config, so there is nothing to migrate and no behaviour to preserve.

Subject: [PATCH 060/885] fix(TWO-25193): fill address from payment-step
 company search
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Selecting a company in the payment-step picker filled nothing: its
select2 processResults never mapped the API's `lookup_id` onto the
result item, and the select handler never fired the company-detail
request. The shipping-step picker did both. Two hand-maintained
copies of the same builder is why they drifted.

Extract the three genuinely identical pieces into
`Two_Gateway/js/model/company-search`:

- buildSearchAjaxOptions() — the select2 ajax block (search URL +
  result mapping, lookupId included)
- lookupCompanyAddress()   — GET /companies/v2/company/{lookupId},
  gated on config.isAddressSearchEnabled
- applyAddress()           — write city/postcode/street and fire change

Both renderers now consume it. The gate is unchanged: ConfigProvider
exposes isAddressSearchEnabled, which Model\Config\Repository already
computes as company-search AND address-search, so the payment step
honours exactly the same admin settings as the shipping step.

Divergent glue (selectors, placeholder / manual-entry chrome,
customerData vs KO observables, order-intent side effects) stays
duplicated in the two call sites — see PR body for the reasoning.

Tests: new Test/Js/company-search-address-lookup.test.js covers
lookupId capture, address fill with the flag on, and no detail call
with the flag off, for both call sites. amd-harness gains the browser
globals (URLSearchParams, unescape) the shared module needs.

Subject: [PATCH 061/885] TWO-25191/chore: drop dead
 two_brand_synthesis/admin_form config node
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The `two_brand_synthesis/admin_form/enabled` default in
`etc/config.xml` has had no reader since magento-plugin PR #181
(ABN-415) removed the flag gate from `SynthesiseBrandAdminForm`.
That PR deliberately left the node behind as harmless; the problem is
the 16-line comment above it, which still described a live kill switch
and told readers to "flip to 0 only to debug" — a knob that does
nothing. Remove both.

Also de-stales the section header comment, which listed `admin_form`
as a layer that "will add its own sibling here", and replaces it with
a pointer to why admin-form synthesis is unconditional.

`SynthesiseBrandAdminFormTest` stays valid: its two assertions pin the
class shape (no ScopeConfigInterface in the constructor, no FLAG_PATH
constant), not the config path — the path appears only in the
explanatory docblock. Added a third test that pins the config.xml
removal so the node cannot quietly reappear.

Note: `etc/config.xml` is touched once here for both halves of
Linear TWO-25191 — this commit's `admin_form` removal and the
following commit's `hide_when_overlay_installed` move. Splitting one
small file across two commits would have been more confusing than the
shared touch.

Subject: [PATCH 062/885] TWO-25191/refactor: move hide-payment-section flag
 out of merchant namespace
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

`payment/two_payment/hide_when_overlay_installed` sat in the
merchant-owned namespace, where every other key is a real merchant
setting backed by an admin field. It is neither: it is a deploy /
rollout switch with no admin field, read only by
`Plugin/Config/Structure/HidePaymentSection.php`. Move it to
`two_brand_synthesis/hide_payment_section/enabled`, next to the other
brand-synthesis rollout knobs.

Read-fallback so nobody's setting is silently dropped: `shouldHide()`
reads the new path, falls back to the legacy path when the new one is
absent, and only then applies the code-side default of 1 (hide).
"Absent" is null/empty-string, not falsy, so an explicit `0` on either
path is honoured rather than falling through.

That requires NOT declaring a default for either path in
`etc/config.xml` — a declared default is never null, which would make
the fallback dead code. The default therefore lives in
`HidePaymentSection::DEFAULT_HIDE`, and a unit test pins the absence of
both config.xml nodes so the fallback cannot be silently disabled.

Also corrects a long-standing docblock lie: the advertised
`bin/magento config:set payment/two_payment/hide_when_overlay_installed 0`
recipe never worked. `config:set` and `config:show` validate the path
against the admin `system.xml` structure, and this flag has no admin
field. Verified on Magento 2.4.6 — both the old and new paths return
`The "..." path doesn't exist. Verify and try again.` The working route
(also verified) is a `system.default.*` entry in `app/etc/env.php` plus
`cache:flush`; the docblock now documents that instead.

Subject: [PATCH 063/885] TWO-25197/feat: stamp deployed commit SHA onto
 client_v telemetry
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Support enquiries could only be tied to a release line, not to the
exact code running: `client_v` carried `payment/<code>/version` alone,
which covers every build of that release. It now carries
`<version>+<sha7>` of the commit the deployed module was built from,
e.g. `2.1.2+795f8ca`.

The SHA resolution already existed, but only inside the admin Version
block. It is extracted to `Two\Gateway\Model\Provenance`, injected into
both the block and `Model\Config\Repository` — one owner of the regex,
and no Repository -> Block dependency.

Provenance handles both deploy shapes, unchanged in behaviour:
  - Packagist/composer install (no .git anywhere): the installed
    registry's source/dist reference.
  - gitSync dev install (no composer package): the `.git` gitlink file
    naming its worktree after the SHA. The gitlink is now also looked
    for one level up, so a monorepo sub-path module (the ABN overlay
    ships its gateway at <repo>/plugin) resolves its own commit on the
    admin panel instead of showing nothing.
Neither present -> '' and a bare version string; nothing throws, and
the `+` is appended only when a SHA actually resolves, never as a
trailing `+`.

`getExtensionDBVersion()` deliberately keeps returning the unstamped
configured version — callers compare it against release numbers.

`+` is not URL-safe in a query value (it decodes to a space), but
`addVersionDataInURL()` emits through `http_build_query`, which
percent-encodes it. Verified against a real 2.4.8 install:
`...?client=Magento&client_v=2.1.2%2B795f8ca`, decoding back to
`2.1.2+795f8ca`.

From 08e39c4fa6809269eccd6e40a2204c94a1fbd152 Mon Sep 17 00:00:00 2001
From: Douglas Lindsay <dlindsay@two.inc>
Date: Tue, 28 Jul 2026 10:02:07 +0100
Subject: [PATCH 064/885] refactor: TWO-25202: collapse the two address-lookup
 toggles into one
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

`isAddressSearchEnabled()` required both `enable_company_search` and
`enable_address_search` to be on. WooCommerce and PrestaShop each have a
single toggle; Magento was the outlier. It now reads
`enable_address_search` alone.

`enable_company_search` is retained — it keeps its own separate job,
gating the shipping-step company-search widget only.

A data patch collapses the old AND into the single key: wherever the old
conjunction resolved to OFF, `enable_address_search` is pinned to 0 at
that scope (default / website / store, parent-first so no redundant rows
are written). Every merchant's effective behaviour is unchanged. Both
keys default to 1, so untouched installs are unaffected.

Also: admin help text now states that `enable_company_search` governs
company search in the shipping address field only — company search on the
payment method step is always available — and the stale AND-describing
comments in the JS are corrected. Adds the TWO-25202 regression pin that
re-searching overwrites address and company id.

+/**
+ * TWO-25202: address lookup used to require BOTH `enable_company_search`
+ * and `enable_address_search` to be on (the AND lived in
+ * Model\Config\Repository::isAddressSearchEnabled). It now reads
+ * `enable_address_search` alone, so this patch folds the old conjunction
+ * into that one key: wherever the old AND resolved to OFF, the new single
+ * key is pinned to 0 at that scope. Every merchant's effective
+ * address-lookup behaviour is therefore identical before and after.
+ *
+ * `enable_company_search` is NOT touched or removed — it keeps its own
+ * separate job (gating the shipping-step company-search widget).
+ *
+ * Scope-aware: default, website and store scopes are walked parent-first
+ * and a row is only written where the inherited new value would differ
+ * from the old effective AND, so no needless explicit rows appear in
+ * core_config_data.
+ *
+ * Brand-agnostic: the codes to migrate are discovered from the
+ * `payment/<code>/enable_*_search` rows actually present in
+ * core_config_data. A code with no stored rows cannot need a write —
+ * both keys default to 1 (etc/config.xml), so the old AND was already
+ * ON — which is why untouched installs are unaffected.
+ *
+ * Idempotent: a second run re-derives the AND from the already-collapsed
+ * values (address 0 => AND 0 => desired 0 => no change) and writes
+ * nothing. Only ever writes 0, never 1.

Subject: [PATCH 065/885] TWO-25205/feat: add .two-deployed-commit stamp,
 gitlink-first resolution
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Provenance had no support for a build stamp, so a zip-dropped module —
an overlay package's GCS / release-asset zips, unpacked straight into
app/code — reported no commit at all: it carries neither a .git gitlink
nor a Composer registry entry, which were the only two signals resolve()
knew about.

Adds commitFromStamp() reading `.two-deployed-commit`, and adopts the
org-wide resolution order Doug settled for all six plugin artifacts:

  .git gitlink -> Composer reference -> .two-deployed-commit stamp

The order is freshness-ranked, not confidence-ranked. The gitlink is the
only signal reflecting what is checked out right now; the Composer
reference is recorded once at install time; the build stamp is frozen at
build time and so is the most likely of the three to be stale. This
flips the previous composer-first order. PrestaShop (PR #92) and
WooCommerce (PR #380) already match.

The stamp reader mirrors the gitlink and composer.json two-place lookup
($modulePath and dirname($modulePath)) because a sub-path module's stamp
sits at the archive root. It caps the read, validates
/^[a-f0-9]{7,40}$/i, uses @, never throws, and returns the 7-char
prefix; a malformed or empty stamp falls THROUGH to the next signal
rather than surfacing junk as a commit.

`make archive` writes the stamp into a mktemp dir OUTSIDE the repo and
injects it with `git archive --add-file`, so the working tree is never
dirtied. `.two-deployed-commit` is gitignored as a second guard.

+ *  2. Composer/Packagist install (the 2.0 merchant distribution). The
  *     module lives under vendor/ with no .git of any kind; Composer's
  *     installed registry records the exact source/dist reference —

+ *     Composer registry entry — so neither signal above exists. `make
+ *     archive` stamps a `.two-deployed-commit` file into the zip at build

- * point returns '' rather than throwing, so callers degrade to a bare

Subject: [PATCH 066/885] TWO-25209/docs: refer to branding overlays
 generically, not by partner brand

magento-plugin is a public repo; the partner brand overlay is private.
Naming it in comments and test fixtures is a leak.

Comments and docblocks only, plus one test fixture package name.
No behaviour, config key, class or method name changes.

Subject: [PATCH 067/885] TWO-25209/docs: refer to branding overlays
 generically, not by partner brand

This is a PUBLIC repo; the partner brand overlay is private and must
never be named here. Scrubs the brand from comments, docblocks and
test fixtures.

- prose mentions -> "a branding overlay" / "an overlay package"
- private-team ticket refs -> plain-English descriptions of the bug
- docblock namespace examples -> neutral Overlay\\Gateway placeholders
- test fixture ids/paths -> neutral overlay_* equivalents
- private repo names -> "the overlay repo"

Comments, docs and test-local fixtures only. No behaviour, config key,
class or method name changes.

Subject: [PATCH 068/885] style(TWO-25213): normalise pre-existing prettier
 drift in touched files

gateway_method.html, style.css and brand-overlay-guide.md were already
non-compliant with the repo's own prettier hook on staging. Normalising
them in a separate commit so the behavioural diff that follows is
legible rather than buried in reformatting.

No behaviour change; prettier is not a CI gate in this repo (it runs
only via .pre-commit-config.yaml), so this is debt paydown on the three
files the next commits touch, not a repo-wide sweep.

Subject: [PATCH 069/885] feat(TWO-25213): add three-state
 intent_approved_notice brand seam
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Adds brand.xml <intent_approved_notice>, carrying it through Loader →
Descriptor → BrandRegistryInterface so a brand can override or switch
off the buyer-facing "order intent approved" notice.

Three states, all meaningful:

  absent             ⇒ platform default translated copy, notice ON
  present, empty     ⇒ notice suppressed entirely (no DOM element)
  present, non-empty ⇒ verbatim company-known copy template
                       (%1 = product name, %2 = company name)

Absent must not collapse onto present-and-empty, or the off switch
becomes unreachable — Loader uses isset(), which SimpleXML reports true
for an empty element, and Descriptor exposes null / '' / template. The
value is trimmed so a pretty-printed empty element reads as suppressed
rather than as a whitespace template.

The Two brand deliberately declares no element, keeping the notice ON.

LoaderTest covers all three states plus the self-closing and
whitespace-only spellings; all five new assertions were mutation-checked
(null→'', dropped trim(), isset()→truthiness) and each mutant failed.

Subject: [PATCH 070/885] feat(TWO-25213)!: converge intent-approved copy and
 interpolate company name
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Buyer-facing copy change. The notice now names the buyer's company:

  "Your invoice with %1 is likely to be accepted for %2, subject to
   additional checks."

with a company-unknown fallback that drops the "for %2" clause. Both
strings match the wording PrestaShop and WooCommerce are converging on,
so all four checkout surfaces read identically.

The company name is only ever known client-side, so ConfigProvider emits
both resolved variants plus a {{companyName}} token for the renderer to
substitute. The token is passed as an explicit second __() argument
rather than left dangling, so both placeholders stay in the msgid and
translators see the whole sentence.

BREAKING (internal): checkoutConfig key `orderIntentApprovedMessage` is
replaced by `orderIntentApprovedNotice`, which is null when the active
brand suppressed the notice. The old key had exactly one consumer, the
Luma renderer.

nb_NO / nl_NL / sv_SE translations updated — the msgid changed, so
leaving the CSVs alone would have silently dropped those locales back to
English.

Subject: [PATCH 071/885] fix(TWO-25213): render intent-approved notice
 persistently in the Luma tile
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

On Luma the approval reassurance was effectively invisible: the renderer
called messageContainer.addSuccessMessage(), which lands in the KO
getRegion('messages') region, and checkout clears that region on every
update. Buyers rarely, if ever, saw it.

Replaced with a persistent inline element inside the payment-method tile,
next to the term chips, matching PrestaShop's treatment and its
`two-order-intent-message approved` class name so the four platform
surfaces stay greppable. The element is emitted only when the notice text
is non-empty, so a brand that suppresses it gets no element at all rather
than an empty wrapper.

Set/clear discipline — "persistent" is narrower than "forever":

  set    on approval
  clear  on decline, on intent error, and whenever companyName or
         companyId changes (the approval was for the previous company)
  KEEP   across placeOrder()'s messageContainer.clear(), i.e. a failed
         local validation does not discard it; that is the whole point
         of moving off the message region

The observable is created in initOrderIntentApprovedNotice() rather than
declared in `defaults`, because `defaults` entries are copied onto each
instance by reference — a ko.observable() there is shared across every
renderer instance, and Luma re-creates this renderer whenever the
payment-method list refreshes. Same footgun already documented against
isPlaceOrderActionAllowed.

Company-name substitution uses a replacer function, not a replacement
string, so `$&` / `$1` in a company name are taken literally.

DECLINED and error messaging is unchanged.

Ten new jest specs cover the set/clear matrix; all were mutation-checked
(dropped clear on error, dropped clear on decline, dropped companyId
subscription, string-form replace, dropped suppression guard) and every
mutant failed.

+
+### `intent_approved_notice` — a three-state switch
+
+Most optional elements have two states (absent ⇒ default, present ⇒
+override). This one has three, because "no notice at all" is a
+legitimate brand choice and cannot be expressed by omission:
+
+| brand.xml                                            | Behaviour                                                                                                              |
+| ---------------------------------------------------- | ---------------------------------------------------------------------------------------------------------------------- |
+| element absent                                       | Platform default translated copy; notice **ON**.                                                                       |
+| `<intent_approved_notice></intent_approved_notice>`  | Notice **suppressed entirely** — no element is emitted into the DOM, not an empty wrapper.                             |
+| `<intent_approved_notice>…</intent_approved_notice>` | The content is used verbatim as the company-known copy template. `%1` = brand product name, `%2` = buyer company name. |
+
+Whitespace-only content counts as suppressed, so a pretty-printed empty
+element behaves as expected. `Loader` distinguishes absent from
+present-and-empty with `isset()`; `Descriptor::getIntentApprovedNotice()`
+returns `null` / `''` / the template respectively, and callers must not
+collapse the first two — doing so makes the off switch unreachable.
+
+The company-unknown copy variant always stays on the platform default.
+In practice it is unreachable: an order intent is only ever placed once
+the buyer's company name **and** company number are known.
+
+The notice is rendered by both storefront renderers as a persistent
+inline element with class `two-order-intent-message approved`, inside the
+payment-method tile. The same class name is used on the WooCommerce and
+PrestaShop plugins, so the four checkout surfaces stay greppable.

Subject: [PATCH 072/885] fix(e2e): advance the Luma checkout to the payment
 step before asserting availability
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The checkout journey polled getAvailablePaymentMethods() while the checkout
was still on the shipping step, where Magento leaves the list empty by
design: on a non-virtual quote checkoutConfig.paymentMethods is empty on
page load and payment-service is only populated from the
shipping-information POST that the Next button triggers.

It passed until 2026-07-13 only as a side effect of the reactive
payment-availability refresher pushing the server's method list into
payment-service from the shipping step. That component now correctly
no-ops when the availability key (grand total + tax) is unchanged, and
selecting free shipping on the staging store leaves the totals untouched,
so nothing populated the list and the poll timed out on [].

Add goToPaymentStep(), which clicks the store's real Next button and waits
on Magento's own step-navigator for the payment step, and call it before
the assertion. The method itself was never gated off — a REST probe of the
same quote returns two_payment.

Subject: [PATCH 073/885] feat(TWO-25218)!: split intent-approved notice into
 switch + copy override
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

TWO-25213 shipped one brand.xml key carrying three states, where
"present but empty" meant "notice off". That conflated on/off with
wording, expressed a decision as the absence of content, and made an
intentional off switch indistinguishable from an unfinished string — any
tidy-up deleting the "empty, unused" element silently turned the notice
back on.

Two keys now:

- <intent_approved_notice_enabled> — explicit boolean on/off switch.
  `true`/`false` only; absent is the documented default `true`, which is
  what keeps a third-party overlay that declares nothing on ON. Anything
  else is an error, not a silent third behaviour: brand.xsd restricts the
  element to the enumeration true|false so developer mode fails at config
  validation, and Loader additionally throws \DomainException naming the
  path, element and bad value, because nothing validates brand.xsd in
  production mode. Same treatment <surcharge_rounding_steps> already gets.
- <intent_approved_notice> — copy override only. Keeps its name, loses the
  switch meaning. Absent/empty/whitespace-only all normalise to null;
  empty is now INERT. getIntentApprovedNotice() never returns ''.

xs:boolean is deliberately not used — it would also accept 1/0, and this
switch is meant to read as a decision.

BREAKING CHANGE: an empty <intent_approved_notice> no longer suppresses
the notice. Brands that want it off must declare
<intent_approved_notice_enabled>false</intent_approved_notice_enabled>.
Merge order matters: this parent first, then the brand overlay, then the
Hyvä extension — the parent owns the parsing.

Renderer behaviour is unchanged: ConfigProvider still ships null for a
suppressed notice and the KO template emits no element at all. Only the
condition that produces null moved from the copy override to the switch.

Subject: [PATCH 074/885] test(TWO-25218): cover the boolean switch and the
 now-inert copy override
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

LoaderTest: true, false, absent (=> true), surrounding-whitespace
tolerance, and a data-provided invalid set that must throw — including
the 1/0 spellings xs:boolean would have accepted and the empty element
that used to mean "off". Copy key: absent, empty, self-closing and
whitespace-only all resolve to null (never ''), non-empty passes through
verbatim, and one case asserts the two keys stay independent.

ConfigProviderIntentApprovedNoticeTest is new and deliberately thin: the
notice resolution touches only $brandRegistry, so it is reached via
newInstanceWithoutConstructor plus that one injected collaborator rather
than standing up the whole checkout graph. It pins the thing that would
regress silently — suppression keyed off the switch, not the copy
override, including the disabled-with-an-override case.

Every new assertion was mutation-checked against a deliberately broken
production path.

Subject: [PATCH 075/885] docs(TWO-25218): rewrite the intent-approved notice
 contract
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The guide documented the superseded three-state switch in the present
tense, which is worse than no doc — both people and agents read it as
authoritative. Replaced with the two-key contract: element table, the
accepted-values table for the switch, absent/invalid behaviour and where
each error surfaces, and the copy override's inert-empty semantics.

Also documents the migration hazard rather than papering over it: a new
parent plus a stale overlay resolves to notice ON, which is wrong but not
broken. Making empty a hard error would turn a deploy-order window into a
broken store, so empty stays inert and the merge order (parent, then
overlay, then Hyvä) is the mitigation. No legacy-compat path.

+### The intent-approved notice — two keys, one each for on/off and wording
 
-Most optional elements have two states (absent ⇒ default, present ⇒
-override). This one has three, because "no notice at all" is a
-legitimate brand choice and cannot be expressed by omission:
+The notice is a buyer-facing "order intent approved" reassurance line
+rendered inline in the checkout payment tile. It is controlled by **two
+independent keys**: whether it shows, and what it says.
+
+Historically (TWO-25213) there was one key with three states, where
+"present but empty" meant "off". That conflated two unrelated meanings,
+expressed a decision as the absence of content, and made an intentional
+off switch indistinguishable from an unfinished string — any tidy-up that
+deleted the "empty, unused" declaration silently turned the notice back
+on. TWO-25218 split them. **Do not overload one key with both meanings
+again.**

+
+* `brand.xsd` restricts the element to the enumeration `true|false`, so
+  developer-mode config validation fails loudly; and
+* `Model\Brand\Loader` throws a `\DomainException` naming the offending
+  `brand.xml` path, the element and the bad value — the same treatment
+  `<surcharge_rounding_steps>` gets in the same method.
+
+Note `xs:boolean` is deliberately **not** used: it would also accept `1`
+and `0`, and this switch is meant to read as a decision.

-Whitespace-only content counts as suppressed, so a pretty-printed empty
-element behaves as expected. `Loader` distinguishes absent from
-present-and-empty with `isset()`; `Descriptor::getIntentApprovedNotice()`
-returns `null` / `''` / the template respectively, and callers must not
-collapse the first two — doing so makes the off switch unreachable.
+`Descriptor::getIntentApprovedNotice()` returns `null` for the first two
+rows and the template for the third; it never returns `''`. The switch
+above is what `Model\Ui\ConfigProvider` consults to decide whether to ship
+a payload to the renderer at all.
+
+#### Migration hazard: deploy order
+
+A **new parent** plus a **stale overlay** — one that still carries an
+empty `<intent_approved_notice>` and no
+`<intent_approved_notice_enabled>` — resolves to notice **ON**. That is
+wrong for that brand, but not broken. Making an empty copy element a hard
+error would turn the deploy-order window from "wrong notice" into "broken
+store", which is worse, so empty stays inert and there is deliberately no
+legacy-compat path that resurrects empty-means-off.
+
+The mitigation is **merge order**: `magento-plugin` (parent, owns the
+parsing) → `magento-abn-plugin` (overlay) → `magento-hyva-extension`. Out
+of order there is a window in which Hyvä renders the notice for a brand
+that asked for it off.
+
+Hyvä additionally guards the reverse skew with `method_exists()` against
+an older parent that lacks the registry method — a missing method means
+"no brand opinion", i.e. notice ON.
 
 The company-unknown copy variant always stays on the platform default.
 In practice it is unreachable: an order intent is only ever placed once

Subject: [PATCH 076/885] TWO-25216: enforce surcharge tax treatment on every
 payment-section save
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

A field backend model only runs when its own field is part of the save,
so the guard on surcharge_tax_class never fired for a save triggered by
another field — `config:set surcharge_type percentage` slipped through,
and a shop already stored as enabled-with-blank-treatment was never
forced to fix it.

Add a second guard on the Surcharge Method field. That field is posted
on every admin save of the payment section, which turns the pair into an
effective section-save guard. The shared invariant moves into
AbstractSurchargeTreatmentGuard so both guards agree exactly, stay
brand-aware (sibling paths derived from the field's own path), and treat
a pre-existing legacy flat rate as an explicit choice — including a rate
of 0. The Custom-requires-legacy-rate check stays on the tax class field.

Save path only: nothing runs on config page load, and the rejected save
leaves the merchant on the same section, where the treatment dropdown is.

+ * part of the save, so a single guard on the treatment selector could never
+ * see a save that only touched the Surcharge Method (or any unrelated field
+ * in the section). Both the Surcharge Method field and the Surcharge Tax
+ * Treatment field therefore extend this class: the admin section save posts
+ * every visible field in the group, so the Surcharge Method guard runs on
+ * every admin save of the payment section — including saves of a shop that
+ * is already sitting in the enabled-with-blank-treatment state.
+ *
+ * "Explicitly selected" deliberately includes the deprecated legacy flat
+ * rate (payment/<code>/surcharge_tax_rate): merchants configured before the
+ * tax-rule selector existed have made a choice, and must not be blocked.
+ * All emptiness checks are null/'' checks, never truthy — a configured rate
+ * of 0 or "0.00" is a real value.
+ *
+ * Sibling config paths are derived from the field's own path so the rule is
+ * brand-aware: synthesized brand forms save under payment/<brand_code>/ and
+ * get identical enforcement.
+ *
+ * Nothing here runs on config page load — this is the save path only, and it
+ * throws a LocalizedException, which Magento renders as an admin error

Subject: [PATCH 077/885] TWO-25216: cover the section-save surcharge treatment
 guard
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Adds the already-broken-shop path (surcharge_type posted unchanged while
the stored treatment is blank), the legacy-flat-rate carve-out including
the falsy-zero trap, enable-and-pick-in-one-save, and a wiring assertion
that system.xml declares both backend models — the wiring is the fix.

Subject: [PATCH 078/885] TWO-25216: document the write paths the guard cannot
 reach
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Verified against Magento 2.4.6 in a real container, not assumed:
`bin/magento config:set` addresses fields by config path, which
Config::setDataByPath reads as section/group/field — that never resolves
to a system.xml element for these fields, so no field backend model runs
(the pre-existing guard was never reached by config:set either, despite
the old comment claiming it was). Inherited ("Use Default") fields go
through the delete transaction, so beforeDelete runs, not beforeSave.

Records both, plus direct core_config_data writes, on the shared guard
instead of leaving a comment that overstates coverage.

 generically, not by name

magento-plugin is a public repository and the overlay repo slug carries
the partner's initials. The merge-order note is the only thing that
needed the reference, and it reads the same without it.

Subject: [PATCH 081/885] docs(TWO-25225): describe only the current brand.xml
 contract
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Cut the TWO-25213 -> TWO-25218 before/after narrative for the
intent-approved notice keys; the rule ("two keys, never one") stays,
the history of how we got there goes.

Correct the schema table against etc/brand.xsd and Model/Brand/Loader:
drop `available_payment_terms` and `surcharge_fixed_max`, neither of
which Loader parses nor Descriptor exposes a getter for, and add the
missing `surcharge_rounding_steps`. Rebuild the "adding a brand-driven
field" worked example on `surcharge_rounding_steps` for the same reason
— it was written around the dead `surcharge_fixed_max`.

Fix the cross-platform CSS-class claim: WooCommerce renders
`twoinc-intent-approved`, not `two-order-intent-message`.

Replace the `<minimum_order>` removal story with the current rule and
the three values that now come from GET /v1/merchant.

Subject: [PATCH 084/885] feat(TWO-25228): default every optional checkout
 field to enabled
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

PO number, order note and invoice email shipped disabled by declared
default while department and project shipped enabled, so the same product
presented three different out-of-box checkouts across our plugins. Flip
the three laggards to 1 so all five optional fields render on a fresh
install.

Merchants who made an explicit choice are unaffected: Magento consults
<default> only when no core_config_data row exists for the path and
scope, so a saved "No" keeps its row and keeps winning. Shops that never
touched the flags — or left "Use system value" ticked — pick up the new
default and gain the three fields at checkout on upgrade. That is
intended; Magento's visible:/x-show: bindings read the flag with no
payment-method-selection gate, so the fields appear as soon as the tile
renders.

Add a test that pins the declared defaults against the shipped XML and
cross-checks the flag list against the admin Checkout Fields group, so a
sixth optional field cannot be added later and silently default to off.

Subject: [PATCH 085/885] TWO-25230/ci: add shared bump-level decision script

Patch on staging, minor on main, major via escape hatch: a declared
`.next-major` root file or a discovered `!` / BREAKING CHANGE footer,
whichever implies the higher major. Identical in all six plugin repos.

+#
+# Decide the semantic-version bump level for a version-bump / release run.
+#
+# Convention:
+#   patch  — change landing anywhere other than `main` (i.e. `staging`)
+#   minor  — change landing on `main`
+#   major  — escape hatch. Two independent signals, the higher wins:
+#
+#     Declared  a root `.next-major` file whose first whitespace-delimited
+#               token is the target major, with a short human reason on the
+#               same line. Human-editable and reviewable in the PR that
+#               decides it, so a *planned* major with no single breaking
+#               commit still lands as a major:
+#
+#                   3  # overlay migration, 3.0.0 release
+#
+#     Discovered  a `!` on a conventional-commit type (`feat!:`,
+#                 `TWO-1/fix(scope)!:`) or a `BREAKING CHANGE:` footer in the
+#                 commits under consideration. Covers a break that actually
+#                 happened.
+#
+#   target = max(declared, current_major + (breaking ? 1 : 0))
+#   target > current_major  ->  major, new version is exactly <target>.0.0
+#   otherwise               ->  the branch rule above
+#
+# `.next-major` is deliberately NEVER cleared by CI. The `target >
+# current_major` condition disarms it on its own once the major has shipped,
+# and leaving the file in place keeps the declared intent reviewable. The one
+# thing this scheme can still get wrong is a declaration that has fallen
+# BEHIND the current major, so that is a hard failure (see below) rather than
+# a silent no-op.
+#
+# Usage:  decide-bump-level.sh <branch> [<git-rev-range>]
+#
+# With no range, it is derived as "everything not already accounted for" — see
+# the anchor list below. Deriving it carefully matters: a naive
+# `<last-tag>..HEAD` would re-discover the same breaking commit on every single
+# staging PR and major-bump over and over, because `staging` is only tagged
+# when it reaches `main`.
+#
+# Writes `level=`, `set_version=` and `reason=` to stdout as `key=value`
+# lines, and appends the same to $GITHUB_OUTPUT when running under Actions.
+# The full decision — including the declared reason string — is logged on
+# every run, so a stale `.next-major` is visible without digging.

Subject: [PATCH 086/885] TWO-25230/ci: bump on staging too, take the level
 from the shared script
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Release now fires on CI completion for `staging` as well as `main`.
Staging gets a version-bump commit and nothing else — no tag, no GitHub
Release. The inline conventional-commit bucketing no longer decides the
bump level; `.github/scripts/decide-bump-level.sh` does (patch on
staging, minor on main, major via the `.next-major` / `!` escape
hatch). The bucketed release notes stay, main-only, as presentation.

Per-branch concurrency group so a main release and a staging bump don't
serialise against each other.

 ## Releases
 
-Releases are cut automatically once CI passes on `main`.
+Version bumps happen automatically once CI passes on `staging` or `main`. Only `main` cuts a tag and a GitHub Release.
 
-### Tagging (automatic, gated on CI)
+### The version-bump convention
 
-`.github/workflows/release.yml` is triggered by the `CI` workflow completing on `main`. When CI's conclusion is `success`, it:
+The bump level is decided by the branch, not by the commits:
 
-1. Skips itself if the head commit is already a `chore: Bump version` commit, or if the SHA already carries a numeric tag.
-2. Reads conventional-commit types in `<previous-tag>..HEAD` to pick the bump level:
-   - `BREAKING CHANGE:` / `<type>!:` → **major**
-   - `feat:` → **minor**
-   - everything else → **patch**
+| Merge lands on | Bump | Also produces |
+|---|---|---|
+| `staging` | **patch** | nothing else — bump commit only |
+| `main` | **minor** | tag `X.Y.Z` + GitHub Release |
 
-   Linear ticket prefixes are supported (e.g. `INF-123/feat:`).
-3. Runs `bumpver update --<level> --no-tag-commit --no-push` to rewrite `composer.json`, `etc/config.xml`, and `bumpver.toml`.
-4. Tags `X.Y.Z` (bare numeric, matching the established tag convention), pushes the bump commit and tag under the org GitHub App identity, and creates a GitHub Release with a bucketed changelog (Breaking / Features / Fixes / Internals / Other) — so reading the Release page reveals at a glance why the bump was a major / minor / patch.
+A **major** is an explicit escape hatch, and overrides the branch rule on either branch. Two independent signals, the higher wins:
 
-`.github/workflows/merge-back.yml` keeps `develop` fast-forwarded to match `main` after each release. `.github/workflows/auto-pr.yml` keeps a rolling sync PR open from `develop` to `main` with a preview of the next release notes — the same bucketing the actual Release page uses.
+- **Declared** — a root `.next-major` file whose first whitespace-delimited token is the target major, with a short human reason on the same line:
 
-To trigger a release, merge the rolling sync PR into `main`. CI runs on the merged commit; once green, `release.yml` fires.
+  ```
+  3  # overlay migration, 3.0.0 release
+  ```
+
+  Reviewable in the PR that decides it, so a *planned* major with no single breaking commit still lands as a major. The file is never cleared by CI: it disarms itself once the current major reaches the declared one. A declaration that has fallen *below* the current major is a hard CI failure — delete or raise it.
+
+- **Discovered** — a `!` on a conventional-commit type (`feat!:`, `TWO-1/fix(scope)!:`) or a `BREAKING CHANGE:` footer in the commits under consideration.
+
+The new version for a major is exactly `<target>.0.0`, so a declaration may skip more than one major.
+
+`.github/scripts/decide-bump-level.sh` owns this decision and is shared byte-identically across the Magento plugin repos. It logs the full decision — inputs included — to the workflow log on every run.
+
+### Bumping and tagging (automatic, gated on CI)
+
+`.github/workflows/release.yml` is triggered by the `CI` workflow completing on `main` or `staging`. When CI's conclusion is `success`, it:
+
+1. Skips itself if the head commit is already a `chore: Bump version` commit, if the branch tip drifted from the SHA CI signed off on, or if the SHA already carries a numeric tag. (That last check is what makes the merge-back a no-op: after a `main` release fast-forwards into `staging`, staging's tip already carries the tag.)
+2. Calls `.github/scripts/decide-bump-level.sh "$BRANCH"` for the level.
+3. Runs `bumpver update --<level> --no-tag-commit --no-push` (or `--set-version <N>.0.0` for a major) to rewrite `composer.json`, `etc/config.xml`, and `bumpver.toml`, and pushes the bump commit under the org GitHub App identity.
+4. **`main` only:** tags `X.Y.Z` (bare numeric, matching the established tag convention), pushes the tag, and creates a GitHub Release with a bucketed changelog (Breaking / Features / Fixes / Internals / Other). The buckets are presentation only now — the level comes from step 2.
+
+`.github/workflows/merge-back.yml` keeps `staging` fast-forwarded to match `main` after each release (falling back to a sync PR if the two have diverged).
+
+To trigger a release, merge `staging` into `main`. CI runs on the merged commit; once green, `release.yml` fires.

Subject: [PATCH 088/885] fix(firecheckout): stack term chips below their label

Fire Checkout lays out every `.field` in its one-page checkout form as a
label/control row instead of the stacked block layout Luma and Hyva use,
so `.two-term-chips__container` rendered on the same line as the
"Selected payment terms" label.

Make the `.two-term-chips` field a column flex container under the
`.firecheckout` body class only. Column flex restores the stacked order
and, since float is ignored on flex items, it works whether Fire builds
the row by floating the label or by flexing the field. Scoped to
`.firecheckout`, so Luma and Hyva are untouched.

Subject: [PATCH 091/885] TWO-25230/chore: Seed .next-major escape hatch at 2
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The version-bump workflow's major escape hatch reads a root `.next-major`
file: its first whitespace-delimited token is the target major, and a major
bump fires only when that target is above the current major. Seeding it at
the current major (2) makes it inert, but present and discoverable — so a
planned major is a one-character edit in a reviewable PR instead of
archaeology through the bump script.

The file is deliberately never cleared by CI; it disarms itself once the
declared major has shipped.

Subject: [PATCH 092/885] fix(TWO-25233): company-search timeout,
 degraded-state UX and re-render safety
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Company search had four reliability gaps in the Luma checkout, all of
which read to the buyer as "your company is not accepted here":

1. No request timeout. If the API hung, the dropdown never resolved and
   never errored. Adds a 30000ms ceiling to both the search and the
   company-detail lookup, chosen to sit OUTSIDE the server's
   stop_after_delay(10) retry envelope so the client never abandons a
   request the API is still legitimately retrying.

2. Every failure path was indistinguishable from an empty result set.
   Adds an in-field "search unavailable — try again, or enter details
   manually" notice on timeout, network error and non-2xx. A genuine
   abort (the buyer typing on, or teardown) stays silent by design.

3. No signal for a degraded backend. Consumes the new `degraded: true`
   flag, which the API sets on an HTTP 200 with near-empty results when
   its upstream provider timed out, and raises the same affordance.
   Read defensively via a strict `=== true` check: absent means false,
   so responses without the field keep working unchanged.

4. `enableCompanySearch` binds through `$.async`, a MutationObserver,
   and each call adds another one. One-page checkouts re-render the
   payment renderer on every totals/shipping change, so select2 bound
   itself repeatedly to the same node and stale in-flight responses
   resolved into a widget the buyer could no longer see. The binding is
   now once-per-node.

Also adds a module-scoped result cache, so a re-render no longer
re-issues searches the buyer already waited for, and an in-field spinner
reusing the payment-term chips' existing three-dot loader rather than a
second loading idiom. Debounce moves 400ms -> 300ms to match the
WooCommerce and PrestaShop pickers.

Degraded responses are deliberately never cached — pinning the buyer to
a transient upstream failure for the rest of the session would be worse
than the failure.

19 new Jest cases cover forced timeout, abort, network error, degraded
true/absent/non-boolean, cache hit, cache-survives-rebuild, aborted
cache hit, and once-per-node binding on both pickers.

Note: the spinner and notice placement inside select2's search box is

Subject: [PATCH 093/885] fix(firecheckout): beat Fire's field specificity for
 term chips

The previous `.firecheckout .two-term-chips` rule never applied. Fire
Checkout's own stylesheet sets

  .firecheckout .payment-method-content div.field       { display: inline-block }
  .firecheckout .payment-method-content div.field > .label { float: left }

which scores 0-3-1 against the 0-2-0 of the rule it was meant to
override, so the field stayed `inline-block`, the label stayed floated,
and the chips stayed on the label's line. Verified in the browser on the
Fire store view: computed `display` on `.two-term-chips` was
`inline-block`, not `flex`.

Re-scoping the rule onto Fire's own selector plus the chip class scores
0-4-1 and wins without `!important`. Browser-verified before/after on
the Fire store view: chip container top moves from 335px (beside a label
whose bottom is 351px) to 360px, i.e. below it, and the container widens
from 160px to the field's full 318px. Still scoped under
`.firecheckout`, so Luma and Hyva are unaffected.

 /*
  * Theme specific css for fire checkout on the payment term chips.

- * Fire Checkout lays every `.field` inside its one-page checkout form out as a
- * label/control row rather than the stacked block layout Luma and Hyva use, so
- * the chip container is pulled up onto the same line as the "Selected payment
- * terms" label. Making the field itself a column flex container puts the
- * container back below the label, and — because float is ignored on a flex
- * item — it neutralises the row layout whether Fire achieves it by floating
- * the label or by flexing the field. No `!important` needed: this changes the
- * `.field` wrapper's own formatting context rather than fighting Fire's rules
- * on the label.
+ * Fire Checkout's own stylesheet (Swissup_Firecheckout/css/firecheckout-light.css)
+ * lays out every field inside the payment tile as a label/control row:
+ *
+ *   .firecheckout .payment-method-content div.field       { display: inline-block; width: 100% }
+ *   .firecheckout .payment-method-content div.field > .label { float: left; width: auto }
+ *
+ * The floated label leaves the chip container beside it rather than under it.
+ * Making the field a column flex container puts the container back below the
+ * label, and float has no effect on a flex item so the label unfloats too.
+ *
+ * The selector has to carry `.payment-method-content div.field` as well: Fire's
+ * rule scores 0-3-1, so the shorter `.firecheckout .two-term-chips` (0-2-0) that
+ * this replaces lost on specificity and never applied. Adding the chip class on
+ * top of Fire's own selector scores 0-4-1 and wins without `!important`.
+ *
+ * Everything here stays inside `.firecheckout`, so Luma and Hyva are untouched.

Subject: [PATCH 095/885] fix(TWO-25233): address adversarial review round 1
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Three findings from self-review, two of them defeating the point of the PR:

1. The once-per-node bind guard was actively harmful. select2 4.1's own
   constructor opens with `GetData(el, 'select2').destroy()`, so re-init
   already destroys the previous instance — the duplicate-widget scenario
   the guard claimed to prevent cannot happen. What the guard DID do was
   keep the old widget alive across a re-render that reuses the input node,
   with its handlers closed over a DISPOSED renderer: picking a company
   then wrote to dead observables and the order would have gone out with no
   company on it. On the shipping-step picker it additionally skipped the
   placeholder / pre-fill / "Search for company" housekeeping below it.

   The guard is gone. Re-init is the correct way to re-point the widget and
   its `self` closure at the current component. Real re-render safety comes
   from `dispose()`, which now destroys the widget with the renderer that
   owns it.

2. Adding `timeout` made the exact failure this ticket is about hang the
   dropdown on "Searching…" forever. jQuery reports a timeout as
   `status === 0`, and select2's ajax failure closure treats status 0 as an
   abort: it never fires `results:message`, so `hideLoading()` is never
   reached and the loading row stays — directly under the new notice saying
   the search failed. Non-abort failures now go through select2's SUCCESS
   path with an empty result set, which gives it a terminal state to render.

3. The spinner/notice tests were tautological: the jQuery double's fake
   select2 instance had `$dropdown: null`, so `getSearchFieldContainer`
   returned an empty set on every path and both `append` bodies were never
   executed — deleting them left the suite green. The double now models a
   real `$dropdown` with a search box, and the chrome assertions exercise
   the actual DOM writes.

Also from review:

- `setSearching`/`setUnavailable` resolved their target by document
  selector at callback time, so a request issued by a widget destroyed up
  to 30s earlier could paint its failure onto the widget that replaced it,
  and its `always` could strip the live spinner. They now take the bound
  element and resolve through that element's own instance, so a stale
  widget's late response no-ops.
- Nothing removed the appended chrome on close: select2 only detaches the
  dropdown and blanks the search input. A buyer who hit a failure, closed
  the picker and reopened it saw the stale notice until three characters
  were retyped. Both call sites now clear it on `select2:open`.
- The spinner blinked off for 300ms on every keystroke, because select2
  aborts synchronously at the top of the next `query()` and `always` fired.
  The spinner now survives an abort.
- The notice was a `<div>` inside `.select2-search--dropdown`, which
  select2 renders as a `<span>` — invalid nesting, and block-in-inline made
  its spacing and width inconsistent. It is a `<span>` with
  `display: block`.

110 Jest tests pass.

Subject: [PATCH 098/885] fix(TWO-25233): four defects in the merged
 company-search hardening
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Round-2 self-review on PR #282 (already merged to staging) found four real
defects the first round introduced or missed. All are on staging now.

1. `dispose()` destroyed the WRONG widget. It called
   `disableCompanySearch()`, which resolves `companyNameSelector`
   document-wide. The renderer is pushed once per Two-family brand, so a
   checkout offering two of them has two `#company_name` inputs: disposing
   one renderer destroyed the sibling brand's LIVE widget and left it a
   plain text input with no re-init path. dispose() now tears down only the
   node the component actually bound.

2. Our select2 event handlers stacked on every re-render. select2's
   `destroy()` only does `$element.off('.select2')`, so un-namespaced
   handlers survive re-init — and re-init is now deliberate (round 1
   removed the bind guard because select2 self-destroys). One company pick
   therefore fired N `select2:select` handlers after N re-renders: N
   address lookups, N-1 of them closed over disposed renderers, which is
   exactly the dead-observable bug dispose() was added to prevent.
   Handlers are now bound in a `.twoCompanySearch` namespace and cleared
   before each re-bind.

3. A stale widget could still paint on the live one. Round 1 keyed the
   chrome on the bound element, but both call sites re-init select2 on the
   SAME node, so `.data('select2')` always resolves to the current
   instance: a request from the previous widget, in flight for up to 30s,
   painted its failure onto the live picker and its `always` stripped the
   live spinner. Each bind now stamps a token that the chrome must match.

4. Two spinner leaks.
   - A cache hit following an abort never cleared the spinner (the abort
     path deliberately keeps it up), so the dots span forever over a fully
     populated dropdown.
   - Dropping below `minimumInputLength` short-circuits select2's `query()`
     in its decorator without reaching the data adapter, so no transport
     runs and nothing took the spinner down.

Also replaces round 1's empty-success workaround with the correct fix.
select2's ajax failure closure reads `status` off the value the TRANSPORT
RETURNS, not off the jqXHR — and jQuery reports both a user abort and a
timeout as status 0, which is why a timeout was being swallowed as a
cancellation. The transport now returns its own handle and sets
`status = 0` for a real abort only, so a failure leaves `status` absent,
select2 fires `errorLoading`, and `displayMessage()` calls `hideLoading()`.
That is a genuine terminal state, where the previous `success({items: []})`
rendered "No results found" directly under a notice saying the search had
failed.

Tests: 119 passing (was 110). The double now models select2's
destroy-clears-only-its-own-namespace behaviour, so the handler-stacking
regression is actually caught, plus new cases for the returned handle's
status contract, stale-token isolation in both directions, the short-input
reset, the cache-hit spinner clear, and scoped dispose.

Round 3 caught that the round-2 stale-widget fix did not actually work,
and that the guard's shape hid it.

- BLOCKER: neither call site passed `bindToken` to `setSearching` /
  `setUnavailable` — the only two paths that can paint from a stale
  widget. The token reached `clearSearchChrome` alone, which runs on
  `select2:open` and is by definition the live widget, so it never
  needed one. The stale-widget paint bug was therefore still live.
  Cause worth recording: the edit that was supposed to add the argument
  was applied as a text substitution against a pattern that no longer
  matched after a formatter pass, and nothing asserted it had matched.

- `getSearchFieldContainer` guarded with `if (token && ...)`, so it
  failed OPEN: any caller that omitted the token silently bypassed the
  staleness check, which is exactly why the above shipped with every
  model-level token test still green. It now fails closed, and the new
  tests drive the real hooks rather than the model directly, so the
  call-site wiring is covered.

- MAJOR: `markSearchBinding`'s premise was wrong. select2 does NOT abort
  when the buyer drops below `minimumInputLength` — its decorator's
  `query()` fires `results:message` and returns WITHOUT delegating to the
  ajax adapter, and `_request.abort()` lives inside that adapter. So the
  abandoned request stayed on the wire and, up to 30s later, repainted
  results or the "unavailable" notice under "Please enter 3 or more
  characters". The module now tracks the in-flight handle per bind
  (`abortActiveRequest`) and cancels it.

- MAJOR: `disableCompanySearch()` still destroyed via the document-wide
  `$(this.companyNameSelector)` and was still reachable from
  `clearCompany()` — the identical multi-brand hazard just fixed in
  `dispose()`. It now delegates to the scoped teardown. The shipping
  picker's manual-entry handler had the same document-wide destroy.

- MAJOR: the manual-entry and "Search for company" click handlers were
  bound un-namespaced INSIDE an `if (length == 0)` append guard. The div
  survives a re-render, so the guard was false and the handler was never
  rebound — it kept closing over the FIRST, now-disposed renderer, so
  clicking it ran `clearCompany()` / `enableCompanySearch()` against dead
  observables. Exactly the class of bug this branch exists to close.
  They are now namespaced and rebound unconditionally.

- The `dispose only destroys the node this component bound` test was
  tautological: the double memoised nodes by selector, so a document-wide
  destroy hit the same node the component bound and passed either way.
  `$.async` now hands back a node distinct from `$(selector)`, which is
  what the multi-brand duplicate-id case actually looks like. The
  `'status' in handle` assertions were also non-discriminating, since the
  jqXHR double had no `status`; it now carries `status: 0` like jQuery.

Tests: 123 passing (was 119). Verified load-bearing by mutation: dropping
the token from a hook, reverting dispose to a document-wide destroy, and
removing the below-minimum abort each fail a test.

- MAJOR: the below-minimum-input handler cancelled the request already on
  the wire but not select2's PENDING debounced one. select2's ajax adapter
  holds a `_queryTimeout` for our 300ms `delay`, and the
  minimumInputLength decorator short-circuits `query()` before reaching
  that adapter, so it never clears the timer either. Backspacing from four
  characters to two inside 300ms — trivial on key-repeat — fired a fresh
  search for the abandoned term, bringing the spinner back up under
  "Please enter 3 or more characters". Both are cancelled now.

- MINOR: the re-bound "Search for company" link was still looked up by its
  document-wide id, which contradicts the multi-brand reasoning used to
  scope dispose() in the previous commit. With two Two-family renderers
  there is one `#billing_search_for_company` in the page, so the link
  sitting in brand A's field would run brand B's enableCompanySearch().
  It is now appended into, and found from, the bound node's own `.field`
  container by class. Same for the show() inside the manual-entry handler.

  Left alone deliberately: the manual-entry div is appended into the OPEN
  dropdown, and only one picker's dropdown is attached to the body at a
  time, so the document-wide lookup is already effectively scoped there.
  `enterSoleTraderUi()`'s `$(searchForCompanyButton).hide()` is outside
  the binding closure and unchanged.

- MINOR: `activeRequests.set(token, ...)` would throw
  "Invalid value used as weak map key" if a call site omitted the token,
  taking the whole picker down. Guarded, and it now logs instead — the
  degraded behaviour is "no cancel-on-short-input", not a broken search.

Tests: 123 passing.

- MAJOR, self-inflicted last round: moving the append guard from the
  document-wide `#billing_search_for_company` to a per-field
  `.search_for_company` lookup meant the appended div's hardcoded `id`
  could now be minted TWICE — the renderer is pushed once per Two-family
  brand, which is the exact hazard the change was made to fix. Worse,
  `enterSoleTraderUi()` still resolved that id, so it matched only the
  first: brand B entering sole-trader mode hid brand A's link and left its
  own visible. The div no longer carries an id (only `.search_for_company`
  is styled), the `searchForCompanyButton` property is replaced by a
  scoped `searchForCompanyLink()` accessor, and `enterSoleTraderUi()`
  resolves the link BEFORE `clearCompany()` nulls the bound node.

- The `activeRequests.set` guard checked truthiness but its comment
  claimed it prevented a WeakMap key TypeError — a truthy non-object still
  throws. It checks the type now.

- The `_queryTimeout` cancellation added last round had no coverage: the
  test double's fake select2 instance exposed no `dataAdapter`, so the
  branch never executed. The double now models it and a test asserts the
  timer is cleared; verified load-bearing by mutation.

Tests: 124 passing.

Subject: [PATCH 102/885] =?UTF-8?q?fix(TWO-25233):=20round-7=20review=20?=
 =?UTF-8?q?=E2=80=94=20re-enable=20link=20must=20outlive=20the=20widget?=
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Self-inflicted last round. `searchForCompanyLink()` resolved the link from
`_$companyNameField`, but every path where that link is VISIBLE has
already destroyed the widget and nulled the node: "Enter details manually"
runs clearCompany() -> disableCompanySearch() -> destroyCompanySearchWidget()
and then shows the link. So `enterSoleTraderUi()` (and applyPrefetch())
resolved an empty set, hid nothing, and left "Search for company" visible
in sole-trader mode. The id-based lookup this replaced did work here, so
it was a regression.

The `.field` container is now cached at bind time and deliberately NOT
cleared by the teardown, since the link lives in it and has to stay
resolvable after the widget is gone.

Tests: 125 passing, with a case pinning that the link resolves after
destroyCompanySearchWidget(); verified load-bearing by mutation.

Cached search results never expire within a page lifetime, so a company
registered mid-session does not appear until reload. Document that this is
intentional, and that the key is the full request URL, so nobody "fixes"
either.

Comment-only, no behaviour change.

Subject: [PATCH 106/885] fix(TWO-25253): guard the optional
 national_identifier in company search
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

`processResults` read `item.national_identifier.id` unguarded. The field is
optional in the search response — a company may have no identifier in its home
registry, and internal types are stripped from it — so a legitimate hit threw.

The throw happens inside select2's query pipeline, which means it did not cost
the buyer one hit: it took the whole result list down and left the dropdown
stuck on "Searching…" with nothing to act on.

Render the hit with whatever it has instead: the name and highlight, the
identifier suffix only when there is one, and an empty company id otherwise.
Show-over-skip, because the identifier is only the disambiguator between two
similarly-named companies — dropping the hit would remove a company the buyer
can no longer select at all.

Covers all four reachable shapes: `national_identifier` absent, null, `id:
null`, and `id: ""`. Same defect and same fix as the WooCommerce plugin's.

Subject: [PATCH 107/885] fix(TWO-25253): make an identifier-less company pick
 authoritative
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The `national_identifier` guard in company-search.js is right, but it made a
downstream state reachable that nothing handled: a company hit that renders
with an empty `companyId`, which the buyer can then select.

`fillCompanyData()` early-returns unless BOTH name and id are non-empty, so
selecting such a hit set NEITHER observable. Pick a valid company first and
then an identifier-less one, and `companyId()` / `companyName()` kept the
PREVIOUS company's values while select2 displayed the new company's name —
`getData()` / `placeOrderIntent()` submitted company A's organisation number
under company B's name. A silently mis-attributed order is worse than the
crash the guard replaced.

Second defect, in the guard's own comment: it claimed the buyer types the
organisation number into the "still required" company id field themselves.
Neither half was true. `enableCompanySearch()` disables that input, and
jQuery Validation's `elements()` skips `:disabled`, so the template's
`required="true"` was not enforced either. The buyer could not supply the
number and nothing stopped them submitting without it.

Fixed by making the selection authoritative AND giving the buyer the route
the comment promised, rather than by refusing to select the hit. Refusing is
show-over-skip with extra steps: the entire point of rendering the hit is
that the company stays selectable, and a company with no registry identifier
is a legitimate company, not a bad result. The input is a plain text field
with a two-way `value: companyId` binding, so re-enabling it is all that is
needed for the buyer's typing to reach the observable and for `required` to
start being enforced — that option is workable here, so refusing the hit in
the dropdown was not taken.

- `applyCompanyData()` routes a selection: name-but-no-id goes to
  `selectCompanyWithoutIdentifier()`, everything else to `fillCompanyData()`.
- `selectCompanyWithoutIdentifier()` writes the name, CLEARS the previous
  identifier, and re-enables `company_id`. No order intent is placed —
  there is no identifier to place one for.
- `needsManualCompanyId()` / `syncCompanyIdEditable()` carry the
  enable/disable decision. `clearCompany()` was not reused: it has the
  mechanics but also blanks the company name and tears the widget down,
  which is the opposite of keeping a selected company selected.
- The comment in company-search.js now describes what actually happens, and
  points at the code that has to hold for it to stay true.

`fillCompanyData()`'s guard is deliberately left alone — it is load-bearing
for its four other callers, above all the `companyData` section read on
init, where an empty section must not blank live state. Only the two
selection paths bypass it, and only for the name-set/id-empty shape.

Both pickers behave the same. The shipping-step picker was already
authoritative (`setCompanyData()` writes both the section and the DOM field
unconditionally, and never disables its own input); what was missing was the
payment step trusting it, so the `companyData` subscription and its init read
now route through `applyCompanyData()` too. Without that, an identifier-less
company picked on the shipping step was dropped on arrival at the payment
step, leaving the same stale-id mismatch.

Also closes a hole in the four shape tests added with the guard: none
supplied a `lookup_id`, and `toEqual` treats `lookupId: undefined` as equal
to the key being absent, so dropping `lookupId` altogether passed. Asserted
on the key set explicitly, with a fifth row carrying a real `lookup_id` —
address autofill keys on it and is the one thing that still works for an
identifier-less hit. `toStrictEqual` is not usable here: the harness runs
modules in a `vm` context, so every strict compare fails cross-realm with
"serializes to the same string".

Tests: 140 pass. Every new assertion mutation-checked, including the two
paths that were initially unpinned (the subscription and the init read).

Subject: [PATCH 108/885] fix(TWO-25253): derive company_id editability once,
 intent-check a typed number
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Round-2 review of the previous commit, all four majors in its own new code.

1. The editable state was derived on ONE branch. `selectCompanyWithoutIdentifier()`
   called `syncCompanyIdEditable()`; `fillCompanyData()` called nothing, and the
   identifier-less branch was that function's only production call site. Pick an
   identifier-less company (field enabled), then pick a NORMAL one: the registry's
   organisation number was written into a field that stayed ENABLED, so the buyer
   could hand-overwrite it — exactly the state `syncCompanyIdEditable()`'s own
   comment says must not exist. It self-healed only if a later re-render happened
   to re-fire `$.async`.

   Derived in `applyCompanyData()` after BOTH branches instead, so one place
   decides it. Not inside `fillCompanyData()`: that has four other callers
   (`updateAddress()`, the sole-trader prefill paths) which run in modes where
   company search does not own the field, and disabling it there would lock a
   manual-entry buyer out of their own input. The state machine lives on the
   selection paths, so the derivation does too.

   Correcting the previous commit's body, which cannot change: these two helpers
   carry only the ENABLE half of the decision, not "the enable/disable decision".
   That was the defect — nothing carried the disable half. Now
   `applyCompanyData()` carries both.

2. Routing the `companyData` section read through `applyCompanyData()` let a
   stale persisted `{companyName, companyId: ''}` row CLOBBER a live pick: the
   name was overwritten, the identifier cleared, the field re-enabled.
   `companyData` is a localStorage customer-data section, so such a row outlives
   page loads and previous orders, and `fillCustomerData()` is re-callable
   (`applyPrefetch()` → `registeredOrganisationMode()`). Before the routing
   existed that shape was a harmless no-op on the read path; the previous commit
   made it destructive.

   Fixed with an explicit `{authoritative: true}` from the two SELECTION paths
   only — the payment-step picker, and a change NOTIFICATION on the section,
   which is the shipping-step picker writing it. The one-shot read on init is
   not a selection, and may apply a name-only row only when nothing is selected
   yet (the real "renderer initialised after a shipping-step pick" case).

   Chosen over "ignore a section whose id is empty while `companyId()` is
   non-empty" because that rule cannot tell the stale row from the legitimate
   shipping-step pick of an identifier-less company after a valid one — it would
   re-break the mis-attribution this PR exists to fix. Authoritative-vs-read is
   a property of the caller, so the caller states it.

3. `selectCompanyWithoutIdentifier()`'s comment promised an order intent "will
   be placed when the buyer supplies it". Nothing did. `placeOrderIntent()` had
   one caller, inside `fillCompanyData()`, and nothing subscribed to `companyId`
   to re-fire it — so an identifier-less company's order reached the API with no
   credit check behind it at all: no approval notice, no pre-decline.

   Made the promise true rather than deleting it. An order that skips the credit
   check is worse than the crash this PR started from, and the buyer typing the
   number is the moment the check becomes possible.
   `applyManualCompanyId()`, bound to the field's `change` in the one place that
   already owns that node, fires at most once per number the buyer settles on:
   `change` not `input` (once on commit, not per keystroke); returns on empty,
   on a value equal to the one already accepted, and when no company is
   selected. It cannot double up with the picker path — `fillCompanyData()`
   writes the field with `.val()`, which fires no `change` event, and places its
   own intent. `runOrderIntent()` is extracted so both routes fire it
   identically and there is one intent call site.

   The field is deliberately NOT re-disabled once a number is accepted: the
   buyer typed it, so a typo has to be correctable, and a correction re-checks.
   It returns to disabled when a company that HAS a registry identifier is
   picked. Known residual: committing an edited number and picking a company in
   one gesture can place two intents whose responses race — the same race two
   rapid picks have always had, untouched here.

4. `'a normal pick leaves company_id disabled'` could not fail for the property
   it named. It hand-called `syncCompanyIdEditable()`, which production never
   does on that path, and the assertion was already satisfied by the earlier
   `enableCompanySearch()` disable — deleting the hand-call left the suite green.
   That test is what hid defect 1. Replaced with one that drives the real
   `select2:select` handler twice, identifier-less then normal, and asserts
   `disabled === true` with no hand-call.

Minors in the same review:

- A non-string `companyId` (a numeric `national_identifier.id`) coerced to `''`
  and routed a company that HAS an identifier down the identifier-less branch,
  actively CLEARING it. `String()` now, and the normalised pair is passed down
  so `fillCompanyData()`'s own typeof test cannot re-coerce it.
- The `$.async` comment attributed its ordering to `$.async`. Corrected: the
  wrapping `require()` is what puts the body after the synchronous
  `fillCustomerData()`; `$.async` resolves immediately for a node already in the
  DOM, and re-resolves on every `enableCompanySearch()`.
- Two test comments claimed more than the harness can model. Its `require()` and
  `$.async` doubles are both synchronous, so that test pins a revert to the
  hard-coded `true`, not the async ordering; and the `disabled === true`
  assertion straight after `enableCompanySearch()` is a precondition, not the
  property under test. Both now say so.
- `toEqual` on `sections.companyData` had the same undefined-key looseness the
  previous commit fixed elsewhere; asserted on the key set there too.

Order-intent behaviour was previously unpinned in every test — `initialize()`
never runs under the harness, so `isOrderIntentEnabled` was `undefined` and the
branch was dead. Pinned now: exactly one intent on a normal pick, none on an
identifier-less pick, exactly one when the buyer commits a number, none on a
re-commit of the same number or with no company selected.

Tests: 147 pass, 16 in this suite. Every fix mutation-checked — each of the
four majors and every minor was reverted individually and the suite confirmed
RED, including both new order-intent paths. No new assertion stayed green.

Subject: [PATCH 109/885] fix(TWO-25253): drop the inert intent-on-typed-number
 trigger, derive editability from the observables
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Round-4 review of 7f243b5. The `change` handler on `input#company_id` that
commit added never runs in production, and the reasoning it used to keep
`syncCompanyIdEditable()` off `fillCompanyData()` was wrong for one of the four
callers. Both are undone here; everything else in the branch stays.

1. The intent-on-typed-number trigger is REMOVED, not fixed.

   The template binds `value: companyId`. Knockout's `value` binding listens on
   the SAME `change` event and is registered at applyBindings(), i.e. before the
   `$.async` body runs, so ko writes `companyId()` first and
   `applyManualCompanyId()`'s `companyId === this.companyId()` dedup was already
   true by the time it ran. It returned. A typed number placed no intent.

   It fired at all only when the typed value carried stray whitespace, because
   `trim()` then made it differ — which is exactly the shape the test used
   (`'  99999999  '`), so the test passed against a no-op. A plain number would
   have caught it.

   `applyManualCompanyId()`, its `change` binding and the paired
   `.off('change' ...)` are gone, and `runOrderIntent()` is inlined back into
   `fillCompanyData()`, its only remaining caller. Removing the binding also
   removes the document-wide `.off('change' + EVENT_NS)` on `input#company_id`,
   which would have torn a sibling Two-brand renderer's handler off the field —
   the name-field path uses `bindToken`/container scoping for that reason.

   The comment where the promise was now states what actually happens: an
   identifier-less company is never intent-checked. The buyer can type the
   organisation number into the re-enabled field and the order goes out with it,
   with no credit check behind it. Making that work is its own ticket, together
   with the PRE-EXISTING stale-response race on the intent path (no request
   token on placeOrderIntent(), and processOrderIntentSuccessResponse() builds
   its notice from the CURRENT companyName()). Splitting this out removes the
   second concurrent intent source rather than adding it.

2. `company_id`'s editable state is now DERIVED from the companyName/companyId
   observables, subscribed once in enableCompanySearch() and disposed in
   dispose().

   7f243b5 kept `syncCompanyIdEditable()` out of `fillCompanyData()` on the
   grounds that its four other callers "run in modes where company search does
   not own the field". False for `updateAddress()`: it is subscribed inside
   `fillCustomerData()` and fires on every billing/shipping notification, in
   registered-organisation mode, with the picker live. So an identifier-less
   pick followed by any address notification carrying a `company_id` custom
   attribute wrote a registry organisation number into a still-ENABLED field —
   the hand-overwritable state the previous commit's MAJOR 1 was about,
   reopened. The other three callers do hold, but per-caller reasoning is the
   defect; one derivation cannot desync.

3. Comments only, no behaviour: `fillCustomerData()` re-subscribes on every
   call with no dispose and is re-callable via `applyPrefetch()`, so N calls
   mean N `applyCompanyData()` per notification — PRE-EXISTING, flagged so it is
   not read as new, and out of scope. And the `companyData` subscription is
   authoritative only because that section has exactly one writer and the repo
   ships no `sections.xml`; a second writer or a `sections.xml` entry turns it
   into a clobber path.

Tests: the three manual-path intent tests are replaced by one that pins the
honest behaviour (no handler on the field, a `companyId` write places no
intent). The normal-pick and identifier-less-pick intent assertions stay. New
test drives the updateAddress() desync through a real billing-address
notification. The jQuery double's `on()` keeps one handler per event and its
`off()` is a no-op, which is why the ko blocker slipped through — that is now
documented at the top of the file, since nothing there can speak to handler
ordering or coexistence. Two hand-rolled renderer contexts in other suites gain
a `subscribe` on their `companyName` stub. 11 suites, 146 tests, green.

Subject: [PATCH 111/885] docs(TWO-25253): scope the editability claims to
 observable writers

Review of the strip-out found the new comments overclaiming in two places and
one assertion unlabelled. Prose and one test comment only; no behaviour and no
assertion changed.

The subscription catches every writer OF THE OBSERVABLES, not every writer. Two
cases it cannot cover, so applyCompanyData()'s own call is load-bearing rather
than belt-and-braces: a pick writing values identical to the current ones, which
ko does not notify for, and the window before $.async has resolved the field node
on init, when fillCustomerData()'s companyData notification fires synchronously
and the subscription may not exist yet.

clearCompany() is the writer that proves the distinction: it touches the DOM
fields and never the observables, so after "Enter details manually" the field
reads empty and enabled while the observables still hold the previous company's
registry number. Pre-existing and out of scope, now flagged where it lives so it
is not read as new. "One derivation cannot desync" was true only of per-caller
desync, which is what it was written about.

Also noted why N subscriptions per page are harmless: companyName and companyId
are module-level observables shared by every renderer, so N brand renderers each
subscribe, and each computes the identical answer from the same shared state.

Subject: [PATCH 112/885] TWO-25256/ci: compute the version from the PR's
 commits, on the PR

The version used to be decided by the branch a change merged into: patch on
`staging`, minor on `main`. That is not semver - the same change got a
different version depending on where it landed, and the number carried no
information about what changed.

It is now computed from the conventional-commit types of the pull request's
own commits, on the pull request, and committed onto the PR's own branch. With
M the version on `origin/main` and C the version on the PR head:

  breaking (`!` type or `BREAKING CHANGE:` footer) -> (M.major + 1).0.0
  feat                                             -> M.major.(M.minor + 1).0
  anything else                                    -> M.major.M.minor.(M.patch + 1)
  new = max(C, candidate)   ->   no commit when new == C

Four choices in there are deliberate:

1. The range is this PR's commits only (`origin/staging..HEAD`), never the
   cumulative `main..staging`. That range currently contains `feat!:` commits
   in several of these repos, so a cumulative range would re-discover the same
   break on every PR and keep proposing a major.

2. `max()` rather than "bump by one". The computation is then idempotent by
   construction: a re-run, the `synchronize` fired by its own bump commit, and
   a second fix commit on the same PR all compute the same answer and write
   nothing. It also cannot regress, which matters because `main` sits behind
   `staging` here - a raw candidate can compute below the version already on
   `staging`.

3. Only `feat` earns a minor. `chore` / `docs` / `ci` / `test` / `refactor`
   take a patch; the obvious "minor unless everything is a fix" rule would send
   a docs-only PR to a minor.

4. `.next-major` is compared against main's major, not the head's, and a
   declaration below it is a hard error rather than a silent no-op.

Merges to `main` no longer compute anything: they tag the version already in
the tree and cut the Release. The old bump-on-push-to-`staging` and
bump-on-`main` behaviour is removed.

The push goes out under the org GitHub App token, not GITHUB_TOKEN: a
GITHUB_TOKEN push fires no workflows, so CI would never re-run on the bump SHA.
It also sidesteps the GH013 ruleset rejection the old workflow hits, because
the commit now lands on a feature branch and the branch-protection ruleset
targets only refs/heads/{main,release,staging}.

The computation is unit-tested in .github/scripts/test-decide-bump-level.sh
(classification, idempotence, the stale-main clamp, `.next-major`, and range
hygiene), and the version-bump workflow runs those tests before it is allowed
to write anything.

-# Convention:

-#   minor  — change landing on `main`
-#   major  — escape hatch. Two independent signals, the higher wins:
-#
-#     Declared  a root `.next-major` file whose first whitespace-delimited
-#               token is the target major, with a short human reason on the
-#               same line. Human-editable and reviewable in the PR that
-#               decides it, so a *planned* major with no single breaking
-#               commit still lands as a major:
-#
-#                   3  # overlay migration, 3.0.0 release
-#
-#     Discovered  a `!` on a conventional-commit type (`feat!:`,
-#                 `TWO-1/fix(scope)!:`) or a `BREAKING CHANGE:` footer in the
-#                 commits under consideration. Covers a break that actually
-#                 happened.
-#
-#   target = max(declared, current_major + (breaking ? 1 : 0))
-#   target > current_major  ->  major, new version is exactly <target>.0.0
-#   otherwise               ->  the branch rule above
-#
-# `.next-major` is deliberately NEVER cleared by CI. The `target >
-# current_major` condition disarms it on its own once the major has shipped,
-# and leaving the file in place keeps the declared intent reviewable. The one
-# thing this scheme can still get wrong is a declaration that has fallen
-# BEHIND the current major, so that is a hard failure (see below) rather than
-# a silent no-op.
-#
-# Usage:  decide-bump-level.sh <branch> [<git-rev-range>]
-#
-# With no range, it is derived as "everything not already accounted for" — see
-# the anchor list below. Deriving it carefully matters: a naive
-# `<last-tag>..HEAD` would re-discover the same breaking commit on every single
-# staging PR and major-bump over and over, because `staging` is only tagged
-# when it reaches `main`.
-#
-# Writes `level=`, `set_version=` and `reason=` to stdout as `key=value`
+# Compute the version this pull request should land on `staging` with.
+#
+# The version describes the CHANGE, not the branch it is landing on. It is
+# derived from the conventional-commit types of the commits this PR adds, which
+# is what semver actually asks for. The previous scheme ("patch on staging,
+# minor on main") made the number describe the branch rule instead, so the same
+# change got a different version depending on where it merged.
+#
+#   M = version on `origin/main`          - the last released version
+#   C = version on this PR's head         - what the tree currently declares
+#   L = conventional-commit classification of `<base>..<head> --no-merges`
+#
+#   breaking  ->  candidate = (M.major + 1).0.0
+#   feat      ->  candidate = M.major.(M.minor + 1).0
+#   otherwise ->  candidate = M.major.M.minor.(M.patch + 1)
+#
+#   new = max(C, candidate)            # version_compare semantics
+#   new == C  ->  nothing to do
+#
+# Four properties this shape has deliberately, none of them incidental:
+#
+#  1. THE RANGE IS THIS PR'S COMMITS ONLY (`origin/staging..HEAD`), never the
+#     cumulative `main..staging`. The cumulative range currently contains
+#     `feat!:` commits in several of these repos, so every PR would keep
+#     re-discovering the same break and re-proposing a major.
+#
+#  2. THE `max()` CLAMP, not "bump by one from C". This makes the computation
+#     idempotent by construction - re-running on the same head is a no-op, a
+#     second fix commit on the same PR is a no-op, and the version can NEVER
+#     REGRESS. That last part is load-bearing because `main` sits behind
+#     `staging` in these repos: with a stale main the raw candidate can compute
+#     BELOW the version already on staging, and on PrestaShop that would
+#     resurrect an already-run `upgrade/upgrade-<version>.php` filename.
+#
+#  3. ONLY `feat` EARNS A MINOR. `chore`, `docs`, `ci`, `test`, `refactor`,
+#     `build`, `perf`, `style` all take a patch. The obvious-looking "minor
+#     unless every commit is a fix" rule would send a docs-only PR to a minor.
+#
+#  4. `.next-major` IS COMPARED AGAINST MAIN'S MAJOR, not the head's. A
+#     declaration below the released major is always stale, and is a hard error
+#     rather than a silent no-op:
+#
+#         target_major = max(declared, M.major + breaking)
+#
+# PrestaShop-only clause: PrestaShop discovers upgrade scripts BY FILENAME and
+# runs `upgrade/upgrade-<version>.php` only for versions strictly above the
+# installed one. Appending a second migration to an already-installed version's
+# script therefore never runs on a shop that already reached that version -
+# silently, `number_upgraded=0`. So if this PR ADDS a new upgrade script and the
+# rule above produced no version change, force a patch bump so the script gets a
+# filename of its own. Editing an EXISTING script does not trigger this. The
+# clause is inert in the repos that have no `upgrade/upgrade-*.php` at all.
+#
+# Usage:  decide-bump-level.sh [<base-ref>] [<head-ref>]
+#         defaults: origin/staging HEAD
+#         MAIN_REF overrides the released-version ref (default origin/main).
+#
+# Writes `set_version=`, `changed=` and `reason=` to stdout as `key=value`
 # lines, and appends the same to $GITHUB_OUTPUT when running under Actions.
-# The full decision — including the declared reason string — is logged on
-# every run, so a stale `.next-major` is visible without digging.
+# `set_version` is ABSOLUTE and always populated; consumers pass it straight to
+# `bumpver update --set-version`. There is no bump "level" any more - a level
+# cannot express "clamp to what the tree already has".

+#
+# The version now describes the CHANGE, derived from the conventional-commit
+# types of the commits the PR adds, which is what semver actually asks for. The
+# previous scheme bumped by branch rule (patch on `staging`, minor on `main`),
+# so the same change got a different version depending on where it merged. That
+# is not semver, and the number carried no information.
+#
+# Trigger is `pull_request` to `staging` ONLY. In particular:
+#
+#   - NEVER on a `staging -> main` PR. Promotion to `main` does not invent a new
+#     version; it releases the version already in the tree. The `main` side only
+#     tags what is there and cuts the Release.
+#   - No longer on `push:` to `staging`. Bumping after the merge meant the
+#     version that reviewers saw was never the version that shipped, and it also
+#     needed a push to a protected branch (see the token note below).
+#
+# The whole decision lives in .github/scripts/decide-bump-level.sh, which emits
+# an ABSOLUTE `set_version`. It is idempotent by construction (`max()` against

+# workflow's own bump commit, or a second fix commit on the same PR all compute

+#      is no longer the head.
+#   2. The App (id 2603046) holds `bypass_mode: always` on the branch-protection
+#      ruleset in each of these repos.
+#
+# On (2): this scheme also sidesteps the GH013 failure that the old
+# push-to-staging workflow hits, because the bump is now a commit on the PR's

 ## Releases
 
-Version bumps happen automatically once CI passes on `staging` or `main`. Only `main` cuts a tag and a GitHub Release.
+The version is computed on the pull request that lands on `staging`, from that PR's own commits. `main` computes nothing — it tags the version already in the tree and cuts the GitHub Release.
 
 ### The version-bump convention
 
-The bump level is decided by the branch, not by the commits:
+| Change | What happens |
+|---|---|
+| PR into `staging` | the version is computed from that PR's own commits and committed onto the PR's branch (`.github/workflows/version-bump.yml`) |
+| merge into `staging` | nothing — the merge brings in the version its PR computed |
+| `staging` into `main` | nothing is computed; `main` tags the version already in the tree and cuts the GitHub Release |
 
-| Merge lands on | Bump | Also produces |
-|---|---|---|
-| `staging` | **patch** | nothing else — bump commit only |
-| `main` | **minor** | tag `X.Y.Z` + GitHub Release |
+With `M` the version on `origin/main` and `C` the version on the PR head, the PR's own commits (`origin/staging..HEAD`, `--no-merges`) decide the candidate: a `!` type or a `BREAKING CHANGE:` footer gives `(M.major + 1).0.0`, a `feat:` gives `M.major.(M.minor + 1).0`, and anything else — `fix` and `chore`/`docs`/`ci`/`test`/`refactor` alike — gives `M.major.M.minor.(M.patch + 1)`. The result is clamped with `max(C, candidate)`, which makes it idempotent (a re-run, the `synchronize` the bump commit itself fires, or a second fix commit on the same PR all write nothing) and means the version can never regress while `main` is behind `staging`.

+2. If that version differs from the one on the PR head, runs `bumpver update --set-version <X.Y.Z> --no-tag-commit --no-push` to rewrite `composer.json`, `etc/config.xml` and `bumpver.toml`, and pushes the commit onto the PR's own branch under the org GitHub App identity. Otherwise it writes nothing.
 
-### Bumping and tagging (automatic, gated on CI)
+The push goes out under the App token rather than `GITHUB_TOKEN` for two reasons: `GITHUB_TOKEN` pushes do not trigger workflows, so CI would never re-run on the bump SHA; and the App holds the ruleset bypass. Because the commit lands on a feature branch, it is outside `terraform-managed-branch-protection` (which targets only `refs/heads/{main,release,staging}`) entirely.
 
-`.github/workflows/release.yml` is triggered by the `CI` workflow completing on `main` or `staging`. When CI's conclusion is `success`, it:

Subject: [PATCH 114/885] fix(admin): drop redundant surcharge tax treatment
 comment

ABN-476. The help comment under the Surcharge Tax Treatment selector
restated what the selector's own options already convey, so it is
removed from the admin Configuration surface.

Removed from etc/adminhtml/system.xml and from
etc/adminhtml/brand_form_template.xml, which is a tokenised clone of
that file used to synthesise the per-brand admin form -- leaving the
comment there would keep it on the synthesised surfaces. The field's
translate attribute drops "comment" accordingly. The string was not
present in any i18n catalogue, so no catalogue changes were needed.

Subject: [PATCH 115/885] fix(checkout): order optional fields and move order
 note to shipping (TWO-25263)

Field order. Admin listed department, order note, project, PO number,
invoice email; the checkout tile rendered invoice email, project,
department, order note, PO number. Both are now the canonical
cross-plugin order - invoice email, purchase order number, project,
department - with the order note last in the admin pane. Fixed in
etc/adminhtml/system.xml and etc/adminhtml/brand_form_template.xml
(re-sortOrder, since the pane renders by sortOrder and not source order)
and in the checkout template's markup order.

Toggle naming. Adopt the `Show xxx field` wording already used by the
PrestaShop plugin, replacing `Add xxx Field` / `Enable Invoice Emails`.
nl_NL / nb_NO / sv_SE updated.

Order note placement. It now renders in the shipping address area for
Luma, Amasty and Fire Checkout instead of inside the payment tile, and
is a 2-row textarea rather than a single-line input. The wire format is
unchanged: a shared observable (js/model/order-note) is written by the
new shipping-step component and read by the payment renderer's
getData(), so the value still leaves as `payment[orderNote]` and the
DataAssignObserver -> ComposeOrder -> `order_note` relay is untouched.
The tile keeps a fallback copy, shown only while the shipping area has
not claimed the field, so virtual carts and any front-end whose jsLayout
lacks `shipping-address-fieldset` do not lose the field silently.

Tests: new Test/Js/order-note-shipping-area.test.js pins the relay and
the fallback; new Test/Unit/Config/CheckoutFieldOrderTest.php pins the
rendered order (sortOrder-sorted for admin, document order for the
template) in both admin forms and the tile.

+ *
+ * The buyer's order note is collected in the SHIPPING ADDRESS area
+ * (Two_Gateway/js/view/checkout/shipping/order-note) rather than inside the
+ * Two payment tile, but it is still submitted as part of the payment
+ * method's additional data — `payment[orderNote]` — so the server-side
+ * relay is untouched:
+ *
+ *   Observer/DataAssignObserver  reads additionalData['orderNote']
+ *   Service/Order/ComposeOrder   maps it to the API's `order_note`
+ *
+ * A single module-scope ko.observable is what makes that possible: the
+ * shipping-step component writes to it and the payment renderer's
+ * getData() reads from it, with no dependency between the two components
+ * and no change to the submitted key. RequireJS caches the module, so both
+ * sides hold the same observable for the life of the page — including
+ * across the renderer re-creations Magento performs whenever the
+ * payment-method list refreshes.
+ *
+ * `renderedInShippingArea` is a fallback signal, not decoration. The
+ * shipping-step component sets it when it renders; the payment tile keeps
+ * its own order-note field but only shows it while the flag is false. That
+ * covers the two cases where the shipping area is absent or unreachable:
+ *
+ *   - virtual / downloadable-only carts, which skip the shipping step
+ *     entirely, and
+ *   - any checkout front-end whose jsLayout does not carry the
+ *     `shipping-address-fieldset` node the component mounts into.
+ *
+ * Without it, either case would silently drop the field instead of falling
+ * back to where it used to live.

Subject: [PATCH 116/885] docs(admin): record that brand_form_template
 sortOrder beats system.xml (TWO-25263)

Verified on Magento 2.4.8 by dumping Magento\Config\Model\Config\Structure
with the two admin XML files deliberately out of step: the Checkout Fields
pane followed brand_form_template.xml and ignored system.xml's sortOrder
completely. Editing only system.xml therefore looks like a fix and moves
nothing, which is how the previous ordering attempt appeared to work while
the rendered pane stayed wrong.

Subject: [PATCH 117/885] fix(checkout): build the order-note tile fallback as
 a real ko.computed (TWO-25263)

Review follow-up. The tile's fallback visibility was a plain method called
from the template binding (`if: isOrderNoteFieldInTile()`), relying on
knockout's dependency tracking reaching through the call to notice the
shared `renderedInShippingArea` observable. It does, but nothing proved it,
and a regression there shows up as two order-note fields on screen or a
field missing entirely on a virtual cart.

Now `initialize()` builds a per-instance ko.computed from the predicate and
the template binds the computed, so the binding is reactive by construction.
The predicate stays a separate method (`orderNoteFallbackVisible`) so it is
directly unit-testable.

Also makes the Jest harness's ko.computed faithful. It was a one-shot
snapshot that discarded the `owner` argument, so a test could not tell a
reactive computed from a dead one. It now does real dependency tracking via
a shared activeComputation stack. Verified non-vacuous: sabotaging the mock
back to a snapshot fails the new reactivity test and nothing else.

Falsified from the same review round: only three i18n CSVs exist
(nb_NO/nl_NL/sv_SE), all updated; and no selector outside the two templates
references `two_order_note`, whose id is distinct from the fallback's
`two_order_note_payment`.

Subject: [PATCH 118/885] fix(checkout): claim the order-note field on render,
 not construction (TWO-25263)

Review round 2, HIGH. The shipping component claimed the order-note field
from initialize(), but Magento constructs every component in the jsLayout
tree whether or not it is ever painted. So the claim fired even when the
shipping form never rendered, suppressing the payment tile's fallback in
exactly the cases the fallback exists for and leaving the buyer no
order-note field at all:

  - virtual / downloadable-only carts, which never render the shipping step
  - a returning customer with a saved address, where Magento renders the
    shipping address fieldset only inside the "New Address" flow

The sibling address-autocomplete component does not expose this because it
paints nothing and drives the DOM through jQuery $.async; a component that
actually renders a field does.

The claim now comes from the template's `afterRender` (a core Magento
binding, registered globally in Magento_Ui's knockout bootstrap, invoked as
callback.call(viewModel, element)) and is released via
ko.utils.domNodeDisposal when the node goes away, so navigating off a
rendered shipping form hands the field back to the tile.

Also from the same round:
- dispose the isOrderNoteFieldInTile computed in the renderer's dispose();
  it subscribes to a module-scope observable and the renderer is re-created
  on every payment-method list refresh, so each refresh leaked one
- the order-note admin <comment> had been reworded, orphaning its existing
  translations in all three i18n CSVs and silently regressing them to
  English. Comment now describes both placements accurately and the CSV
  keys match it byte-for-byte in nb_NO / nl_NL / sv_SE
- dropped the unverified claim that Fire Checkout picks the field up
- harness: order-note mock hoisted to a module singleton (it is a RequireJS
  singleton in production, and a fresh pair per load would let a test pass
  with the two sides unshared); computed gained a re-entrancy guard, a
  dispose(), and a note that pureComputed sleep semantics are unmodelled;
  added ko.utils.domNodeDisposal so disposal is testable
- tests: pin that CONSTRUCTION does not claim, that disposal releases, and
  that the two templates keep distinct ids; renamed the misleading
  $rendered in the tile-order assertion

Subject: [PATCH 119/885] revert(checkout): drop the order-note move, keep the
 field ordering (TWO-25263)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Removes the part of this branch that moved the buyer order note out of the
Two payment tile into the shipping address area. The field goes back to the
tile exactly as it was on staging — plain single-line input, gated on
isOrderNoteFieldEnabled, submitting payment[orderNote] — but now sits LAST
among the optional fields, which is the ordering this ticket is about.

Reverted because the placement does not work, for a reason that is a
property of the design rather than the implementation: the Luma shipping
step runs BEFORE payment selection, so a Two-owned note rendered in the
shipping address area is shown to every buyer before anyone has chosen a
payment method. A buyer paying by card would see a Two "Order Note" field,
type into it, and have the value silently discarded, because it only leaves
the browser through the Two renderer's getData(). The gate that placement
needs is not knowable at that step. Separately, FireCheckout uses its own
layout handle, so a component mounted only via checkout_index_index.xml
never appears there and the note would silently stay in the tile.

The replacement approach — route the note through Magento's native
quote.customer_note, as the WooCommerce and PrestaShop plugins already do
with their platforms' own fields — is tracked as TWO-25267. That also
removes the enable_order_note toggle Magento alone carries.

Deleted: the shared order-note model, the shipping-step component and its
template, and their Jest suite. Restored to staging: the AMD test harness,
the checkout layout XML, and the payment renderer. The admin order-note
<comment> text and its three i18n translations go back to staging's wording
too, so no translated key is orphaned.

What this branch still carries: the canonical field order (invoice email,
purchase order number, project, department, order note last) in both admin
XML forms and the payment tile, the `Show xxx field` toggle labels with
their translations, the note recording that brand_form_template.xml's
sortOrder beats system.xml, and CheckoutFieldOrderTest.

Both ordering assertions were mutation-tested: swapping two sortOrders in
system.xml and swapping two field ids in the tile template each produce a
real failure, so neither assertion is vacuous.

- * Service/Order/ComposeOrder maps to the API's `order_note`.
- *
- * These tests pin the two things that keep that true:
- *   1. what the shipping-step component writes is what getData() emits, and
- *   2. the payment tile keeps a fallback field for the checkouts where the
- *      shipping area never renders (virtual carts, front-ends whose jsLayout
- *      lacks `shipping-address-fieldset`) — otherwise the field would vanish

- * Shared order-note state (TWO-25263).
- *
- * The buyer's order note is collected in the SHIPPING ADDRESS area
- * (Two_Gateway/js/view/checkout/shipping/order-note) rather than inside the
- * Two payment tile, but it is still submitted as part of the payment
- * method's additional data — `payment[orderNote]` — so the server-side
- * relay is untouched:
- *
- *   Observer/DataAssignObserver  reads additionalData['orderNote']
- *   Service/Order/ComposeOrder   maps it to the API's `order_note`
- *
- * A single module-scope ko.observable is what makes that possible: the
- * shipping-step component writes to it and the payment renderer's
- * getData() reads from it, with no dependency between the two components
- * and no change to the submitted key. RequireJS caches the module, so both
- * sides hold the same observable for the life of the page — including
- * across the renderer re-creations Magento performs whenever the
- * payment-method list refreshes.
- *
- * `renderedInShippingArea` is a fallback signal, not decoration. The
- * shipping-step component sets it from its template's `afterRender` — on
- * actual paint, NOT on construction, because Magento builds every jsLayout
- * component whether or not it is ever rendered. The payment tile keeps its
- * own order-note field but shows it only while this flag is false, which
- * covers the cases where the shipping field never appears:
- *
- *   - virtual / downloadable-only carts, which never render the shipping
- *     step,
- *   - a returning customer with a saved address, where the shipping address
- *     fieldset is only rendered inside the "New Address" flow, and
- *   - any checkout front-end whose jsLayout does not carry the
- *     `shipping-address-fieldset` node the component mounts into.
- *
- * Without it, every one of those would silently drop the field instead of
- * falling back to where it used to live. Claiming at construction time would
- * be worse than not claiming at all: it suppresses the fallback in precisely
- * the situations the fallback exists for.

Subject: [PATCH 120/885] docs(admin): correct how brand_form_template and
 system.xml actually combine (TWO-25263)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Review caught that the note added earlier had the mechanism backwards. It
claimed brand_form_template.xml's sortOrder beats system.xml's. Reading
SynthesiseBrandAdminForm shows the opposite for scalars: it is an
`afterRead` plugin on the config Structure\Reader, and it merges via
deepMergeOverlay($synthesised, $static), so the STATIC system.xml section is
the overlay and its scalar attributes — sortOrder included — overwrite the
synthesised ones.

What actually governs the rendered order is the template's DOCUMENT order.
The plugin runs after Magento's Sorting mapper, and the merged array keeps
the synthesised array's key order, so the sort has already happened by the
time the template's order is re-imposed. That is consistent with what was
observed on 2.4.8 — sortOrder values coming from system.xml while the
sequence followed the template, and perturbing a system.xml sortOrder
changing nothing — but the earlier note drew the wrong conclusion from it.

The practical instruction is unchanged and still the point: for two_payment,
renumbering system.xml alone moves nothing, so both files must agree. The
reasoning is now right, and stated in terms of the plugin rather than an
unverifiable empirical anecdote.

Test strengthened accordingly. It asserted only the sortOrder sequence,
which for this section is not what renders — so a pure reordering of
brand_form_template.xml with every sortOrder left intact would have passed.
It now asserts DOCUMENT order as well, in both files. Verified non-vacuous:
moving the order-note block to the front of the group while touching no
sortOrder fails the new assertion, and did not fail the old one.

Also anchored the tile-order lookup to `<input ... id="x">` rather than a
bare id substring, so an id appearing in a comment cannot satisfy it.
Verified: replacing the real input with a textarea while leaving the id in a
comment now fails, and would previously have passed.

Subject: [PATCH 121/885] docs(admin): brand_form_template's sortOrder is what
 orders the pane (TWO-25263)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Third and final correction to this note. Both previous versions named the
wrong authority.

Verified in source this time: renderBrandTemplate() passes the substituted
template through Magento's own Structure\Converter, whose mapper list ends
with the Sorting mapper. So the synthesised section is ALREADY ordered by the
sortOrder declared in brand_form_template.xml before deepMergeOverlay runs.
The merge then overwrites scalar attributes from the static system.xml —
sortOrder included, which is why the values visible in the merged structure
are system.xml's — but it does not re-sort, because sorting has already
happened.

Net: brand_form_template.xml's sortOrder sets the rendered sequence.
system.xml's sortOrder supplies the merged value and reorders nothing on its
own. The first version of this note said the template's sortOrder won (right
conclusion, wrong reason); the second said the template's document order won
(wrong). Document order carries no runtime weight at all.

The practical instruction has been the same throughout and is the reason the
note exists: renumbering system.xml alone moves nothing, so both files must
be changed together.

The comments are now deliberately shorter and lean on the plugin rather than
narrating the merge, since the narration is what kept being wrong. The test
is the real guard: it asserts the sortOrder sequence AND the document order in
both files, so the two axes cannot drift apart regardless of which one the
runtime honours. Those assertions were already correct — only their stated
rationale was wrong, and it is fixed here.

Also tightened the tile lookup regex to require whitespace before `id=`, so
`data-id="x"` cannot satisfy it, and dropped a dead `/s` flag. Verified:
rewriting a real `id=` to `data-id=` now fails with `no <input> with
id="two_department" in the checkout tile template`.

+                    are system.xml's — but it does not re-sort, because the

+                    exist at all: a field system.xml declares and this template
+                    does not is dropped.
 
-                      - the FIELD ORDER the admin pane renders is this file's
-                        document order, because the merged array keeps the
-                        synthesised array's key order and the sort has already
-                        happened;
-                      - scalar attributes, sortOrder included, are taken from
-                        system.xml, because the static section is the overlay
-                        and its scalars overwrite;
-                      - which fields exist at all is decided here — the
-                        $isChildrenList branch drops any field system.xml names
-                        that this template does not.
-
-                    The practical consequence: for the two_payment section,
-                    sortOrder does NOT determine the rendered order, so
-                    renumbering system.xml alone looks like a fix and changes
-                    nothing. Keep this file's document order and system.xml's
-                    sortOrder saying the same thing.
-                    Test/Unit/Config/CheckoutFieldOrderTest asserts both, in

Subject: [PATCH 122/885] docs: clear the last three places contradicting the
 corrected note (TWO-25263)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Follow-up to the mechanism correction. The rewrite left the false claim alive
in three spots, one of which mattered:

- the document-order assertion's FAILURE MESSAGE still told the reader that
  document order "is what the admin pane renders, so renumbering sortOrder
  alone will not move anything". That string is the first thing a developer
  reads when the test trips, so it was the most likely of all of these to
  propagate the error. It now says document order is pinned for readability
  and to stop the two axes drifting, and names brand_form_template.xml's
  sortOrder as the real authority.
- the payment tile's comment cited etc/adminhtml/system.xml as the source of
  the admin sequence; it now cites both files and points at the one that
  actually orders the pane.
- the note claimed the template's sortOrder orders the pane without
  qualification. Three degraded paths in SynthesiseBrandAdminForm return
  Magento's result untouched — template unreadable, no brands loaded, or a
  per-brand render throwing — and in those the static system.xml order is what
  shows. Stated, with the observation that keeping both files identical (which
  the note already instructs) makes it moot.

The (a)-(e) claim chain itself was independently verified against vendor
source this round: afterRead placement, the Converter's Sorting mapper
running over the synthesised template, deepMergeOverlay not reordering
existing keys, no downstream re-sort in Structure\Data or
Structure\Element\Iterator, vanilla two_payment genuinely going through
synthesis via etc/brand.xml, and the $isChildrenList skip deciding which
fields exist.

Subject: [PATCH 123/885] docs(test): scope the ordering claims to the file
 that actually owns them (TWO-25263)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Last of the comment-layer cleanup.

- The test's class docblock said "the admin pane is sorted by sortOrder" with
  no file qualifier. The docblock covers both data sets, and for the
  system.xml one that is false — its sortOrder supplies merged values and
  reorders nothing. This is the same unqualified phrasing that was wrong
  twice, surviving in the file's top-of-file summary while the inline comment
  20 lines down had it right. Now names brand_form_template.xml as the
  authority and explains why both axes are asserted in both files.
- The duplicate-sortOrder failure message claimed a collision means "their
  rendered order is not determined by the XML", which over-claims for
  system.xml where sortOrder never determines rendered order at all. Scoped to
  the sequence being ambiguous.
- Fixed a rewrap artifact that jammed the exception parenthetical and the next
  sentence onto one 117-char line, losing the paragraph break.

No functional change; assertions untouched.

Subject: [PATCH 124/885] TWO-25269/fix(surcharge): fail closed on zero cap,
 log FX failures
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Two consistency gaps on the FX fail-closed path in SurchargeCalculator.

1. A configured cap of zero reached the pricing payload as `cap => 0.0`.
   Downstream a zero cap is indistinguishable from NO cap, so the request
   applied the percentage UNCAPPED — the opposite of what the merchant
   configured, and an overcharge to the buyer. The docblock claimed
   "limit > 0 supplies cap" but the code tested `!== null`, and a literal
   0 survives the admin grid: SurchargeGrid::validateValue only rejects
   negatives, and only the empty string deletes the config row. Now fails
   closed with a LocalizedException.

   An ABSENT limit is untouched: "no cap" remains a legitimate
   configuration that still sends a non-zero, uncapped percentage. Covered
   by explicit regression tests so the guard cannot be widened later.

2. The fail-closed throws had no ops- or merchant-visible signal. A
   missing FX rate showed the buyer an error while the logs said nothing,
   so a bad currency pair read as an unexplained checkout drop-off. Every
   fail-closed throw now emits addErrorLog with the currency pair and the
   selected term.

Also documents why the "converted cap rounds to 0.00" hazard other
platforms guard against cannot arise here: convertAmount() does no
rounding (`$amount * $rate`) and CurrencyRatesProvider returns null
rather than a zero or negative rate, so FX can never collapse a non-zero
cap to zero.

No constructor changes, so the Two.php / GenericPaymentMethod DI mirror
does not apply.

Subject: [PATCH 125/885] fix(checkout): name the PO field "Purchase order
 number" in the tile (TWO-25271)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Magento's checkout was the only surface anywhere still saying "PO Number".
Every other surface across the three plugins already agrees:

  magento     checkout "PO Number"            admin "Show Purchase order number field"
  woocommerce checkout "Purchase order number" admin "Show Purchase order number field"
  prestashop  checkout "Purchase order number" admin "Show Purchase order number field"

So the one changes to match the five. No admin label is touched, and neither
woocommerce-plugin nor prestashop-plugin needs anything.

Both sites in the payment tile updated: the label's `ko i18n` binding and the
input's `$t()` title attribute.

Translations added for the new msgid rather than left English. Each was
cross-checked against independent sources rather than transliterated from the
admin toggle's wording:

  nb_NO  Innkjopsordrenummer  -> Innkjøpsordrenummer
  nl_NL  Inkoopordernummer
  sv_SE  Inkopsordernummer    -> Inköpsordernummer

THE "PO Number" MSGID IS DELIBERATELY KEPT. It looks orphaned in this repo
after this change, but it is not: magento-hyva-extension calls
__("PO Number") in its own gateway_method.phtml and ships no i18n files of
its own, so it resolves that string against THIS module's catalogues.
Deleting the row would silently drop Hyva's translated label to English in
all three locales.

Consequence worth knowing: until magento-hyva-extension is updated too, Luma,
Amasty and Fire will say "Purchase order number" while Hyva still says
"PO Number". That companion change belongs in that repo, not here.

Subject: [PATCH 126/885] TWO-25269/docs: complete the @throws on
 SurchargeCalculator::calculate

Review finding. The docblock listed only "FX rate is missing or API response
is malformed", but this class now also fails closed when a configured
surcharge cap resolves to zero in the order currency, and it already threw on
a response quoting a currency other than the order's.

A docblock that under-documents which conditions throw is how a caller ends
up with an uncaught LocalizedException on a path it believed was safe.

Subject: [PATCH 127/885] fix(i18n): standardise the PO field label on "PO
 Number" (TWO-25278)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Reverses TWO-25271, which had moved the checkout tile's label the other
way, to "Purchase order number". The decision is now the opposite: one
phrase, "PO Number", on the checkout tile AND on the admin toggle.

Why this direction rather than the longer phrase:

  - no stale catalogue key left behind to maintain
  - no cosmetic-breakage risk for shops upgrading
  - shorter string, which renders better in the tile

Surfaces:

  - view/frontend/web/template/payment/gateway_method.html — the visible
    label and the input's title attribute
  - etc/adminhtml/system.xml and etc/adminhtml/brand_form_template.xml —
    the toggle label, in BOTH files, because SynthesiseBrandAdminForm
    renders the template and then deep-merges system.xml over it, so a
    label changed in only one of them is either overwritten or ignored
    depending on which one you picked

The toggle keeps the "Show <x> field" pattern shared with the invoice
email, project and department toggles, which are untouched.

i18n: "PO Number" already had entries in all three locales, so they are
reused rather than duplicated. The two msgids this orphans are deleted
rather than left in place — "Purchase order number" (added by TWO-25271)
and "Show Purchase order number field". Avoiding a stale key is the
stated reason for choosing this direction, so leaving one would defeat
the point. The new "Show PO Number field" msgid carries the translation
each locale already used for the old toggle, which was already phrased
on PO-nummer in every one of them.

Display copy only. No config path, field id, XML node name, DB value or
API key changes: enable_po_number, payment[poNumber] and
buyer_purchase_order_number are all untouched.

Subject: [PATCH 128/885] fix(i18n): normalise fulfilment spelling in
 system.xml comment

The "Standard / End of Month" payment-terms comment was spelled
"fulfillment" (two l's) in etc/adminhtml/system.xml and "fulfilment"
(one l) in etc/adminhtml/brand_form_template.xml. Same sentence, so
Magento treated it as two distinct translation keys, each needing its
own catalogue row.

Standardise on the single-l "fulfilment" form, which is what the rest
of the display copy and every existing catalogue row already use
("Fulfilment Trigger", "Fulfilment Order Status"). The two keys now
collapse to one.

Display copy only. The /fulfillments API endpoint path, the
getTwoOrderFulfillments() method and the $fulfillments variables are
deliberately untouched, as are the fulfill_trigger and
fulfill_order_status config paths.

No catalogue row was keyed on the retired two-l spelling, so no
re-keying was required.

Subject: [PATCH 129/885] feat(i18n): add missing admin comment and label
 translations
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Admin field comments and labels render through __() unconditionally --
the translate="..." attribute on a <field> is only read by the i18n
extraction tooling, not at runtime. So a string translates as soon as a
catalogue row exists and no code change is needed.

Audit of etc/adminhtml/brand_form_template.xml and
etc/adminhtml/system.xml found five source strings with no row in any
of the three catalogues. Adds them to nl_NL, nb_NO and sv_SE:

Labels:
- Minimum Order Value
- Minimum Order Value Tax Basis

Comments:
- Whether the basket is compared against the minimum including or
  excluding tax
- the "Standard / End of Month" payment-terms explainer
- the surcharge line description explainer

Also drops a stale row keyed
"Description shown to the buyer for the surcharge line item." -- the
old truncated form of the surcharge line description, which no longer
matches any source string and was therefore dead. Its target text is
retained as the first sentence of the replacement row.

Terminology and register follow each catalogue's own existing rows
rather than a dictionary: surcharge = toeslag/tillegg/tillägg, payment
terms = betaaltermijnen/betalingsvilkår/betalningsvillkor, buyer =
koper/kjøper/köpare, tax = BTW/MVA/moms, and the quoted example reuses
the existing "Payment terms fee - %1 days" row verbatim so the admin
sees the string they will actually get. nl_NL uses informal "je" per
catalogue majority.

Placeholders and markup (%1, <strong>, </strong>, <em>, </em>, <br/>)
are byte-identical to the source strings.

Every source comment and label is now covered in all three locales.
The only remaining uncovered strings are the {{tab_label}} template
placeholder and the module name, both correctly absent.

Translations are AI-proposed and want a native reviewer.

Subject: [PATCH 130/885] feat(i18n): translate model-generated minimum-order
 comment

Review follow-up. The Minimum Order Value field's comment is not an XML
text node -- it is generated by
Two\Gateway\Model\Config\Comment\MerchantMinimumOrder, which the two
admin XMLs reference as <comment model="..."/>. Its four __() strings
had no row in any of the three catalogues, so the previous commit
delivered a translated label sitting above an English comment on the
same field.

Adds all four, byte-matched against the __() literals in the model:
- the no-platform-minimum variant of the comment
- the platform-minimum variant (carries %1 and %2)
- "including" / "excluding", substituted into %2

Terminology follows the same catalogue precedents as the rest of this
branch: payment method = betaalmethode/betalingsmetoden/
betalningsmetoden, tax = BTW/MVA/moms, and the tax-basis wording
matches the "Minimum Order Value Tax Basis" label added earlier.

Also retargets one nb_NO row that had left the English loanword
"Fulfillment" in the Norwegian text; it now reads "Oppfyllelse", which
is the term every other nb_NO row uses. No catalogue msgid contains
the two-l spelling any more, in either column.

MerchantMinimumOrder is the only <comment model="..."/> in either admin
XML, so this closes the model-generated-comment gap rather than just
one instance of it.

Translations are AI-proposed and want a native reviewer.

Subject: [PATCH 132/885] fix(i18n): close the minimum-order string cluster

Review round 2. The previous commit translated the bare words
"including" and "excluding", but those are substituted into THREE
parent sentences, only one of which had been translated. The other two
therefore regressed from consistent English to mixed language:

- Model/Two.php's buyer-facing decline message
- Model/Config/Backend/MerchantMinimumOrder.php's save-time validation
  error

Both parents are now translated, so every consumer of the two bare
words renders in one language. Verified by rendering each parent with
the substituted word spliced in.

Two further strings on the same admin screen were making the labels
added earlier ineffective:

- Block/Adminhtml/System/Config/Field/MinimumOrderValue.php overrides
  the field label with "Minimum Order Value, %1" whenever a base
  currency resolves, which is the normal path -- so the bare
  "Minimum Order Value" row was almost always bypassed. Both rows are
  now present; the bare one remains for the currency-less fallback.
- Model/Config/Source/MinimumOrderBasis.php supplies the dropdown
  options "Including tax (gross)" / "Excluding tax (net)", which sat
  in English under the translated "Minimum Order Value Tax Basis"
  label.

Also corrects the sv_SE rendering of the two bare words: "inkluderat"
and "exkluderat" are past participles, which do not fit either parent
sentence. Swedish takes the prepositions "inklusive" / "exklusive",
matching the "Whether the basket is compared..." row added earlier.
nb_NO "inkludert" and nl_NL "inclusief" already read correctly in both
positions.

Every admin- and buyer-facing string in the minimum-order field
cluster is now covered in all three locales.

Translations are AI-proposed and want a native reviewer.

Subject: [PATCH 133/885] fix(i18n): translate the sibling minimum-order
 validation error

Review round 3. beforeSave() in
Model/Config/Backend/MerchantMinimumOrder.php throws two
LocalizedExceptions. The previous commit translated the second one and
left the first, so the same field's save validation rendered in two
different languages depending on which branch tripped.

Adds "Minimum Order Value must be a non-negative number." to all three
catalogues, worded to match the platform-minimum error beside it.

These are the only two __() literals in that file, so the minimum-order
cluster is now genuinely closed: every __() literal across
Config/Backend/MerchantMinimumOrder, Config/Comment/MerchantMinimumOrder,
Config/Source/MinimumOrderBasis, Block/.../Field/MinimumOrderValue and
Two.php's minimumOrderMessage() is covered in all three locales.

Translations are AI-proposed and want a native reviewer.

Subject: [PATCH 134/885] TWO-25279/feat(surcharge): require a merchant tax
 rule for the surcharge treatment

Core's "None" Product Tax Class (id 0) is a platform default, not a rule
the merchant configured, and selecting it silently means "the surcharge is
never taxed, in any jurisdiction". Drop it from the option list; a merchant
who wants an untaxed surcharge builds a 0% tax rule and selects that.

A scope that already stores it keeps the option. Without that carve-out the
select cannot render the stored value, falls back to the placeholder, and
the next admin save posts '' -- which AbstractSurchargeTreatmentGuard
rejects, rolling back the whole payment-section save and locking the
merchant out of saving any field in it. The stored value is read through
getSurchargeTaxClassId(), which maps ''/unset/'custom'/non-numeric to null,
so the identity check against 0 is true only for a genuine "None".

Verified against a real Magento 2.4.6 install through
Magento\Config\Model\Config (the class the admin controller uses), not only
in unit tests: blank save rejected, stored-'0' save accepted and
round-tripped, and force-suppressing the option reproduces the lockout.

Subject: [PATCH 135/885] TWO-25279/refactor(surcharge): stop provisioning our
 own no-tax tax class

Setup/Patch/Data/SurchargeNoTaxClass inserted "Payment Terms Surcharge -
No Tax" into the merchant's own tax_class table, rule-free, so that
selecting it guaranteed an untaxed surcharge. That is the same problem as
core "None" wearing a nicer name: a never-taxed treatment the plugin
fabricated, appearing in the merchant's Tax Rules UI as if they had created
it. Provisioning is removed.

MigrateSurchargeNoTaxSelections repoints every stored selection of that
class at core "None" ('0') -- identical never-taxed behaviour in a
platform-native value, so no shop's checkout tax changes. It matches
payment/<any brand code>/surcharge_tax_class at every scope, because brand
overlays save the same field under their own method code. Migrated scopes
then hold a stored-but-hidden value, which the source model re-injects for
exactly that scope.

The tax_class row itself is deliberately left in place. Core's only foreign
keys onto tax_class.class_id are tax_calculation's two, and this class ships
rule-free, so deletion is not FK-blocked -- but a product's tax class is an
EAV attribute value with no FK at all, so deleting the row would silently
orphan any product a merchant had assigned to it. The patch logs the row id
and its attached-rule count so an operator can remove it by hand.

+ * Retire the plugin-provisioned "Payment Terms Surcharge - No Tax"

+ *
+ * That class was inserted into the merchant's own `tax_class` table by
+ * a former data patch (Setup\Patch\Data\SurchargeNoTaxClass, removed in
+ * the same change as this patch), deliberately rule-free so that
+ * selecting it guaranteed an untaxed surcharge. That is exactly what
+ * the plugin must NOT offer: it is a never-taxed treatment the plugin
+ * fabricated, not a tax rule the merchant configured in Magento, and it
+ * appeared in the merchant's Tax Rules UI as if they had created it.
+ *
+ * This patch repoints every stored selection of that class at core's
+ * "None" (Product Tax Class id 0), which is the same never-taxed
+ * behaviour expressed in a platform-native value — so no merchant's
+ * checkout tax changes as a result of running it. Core "None" is itself
+ * suppressed from NEW selections by SurchargeTaxClassSource; migrated
+ * scopes therefore hold a stored-but-hidden value, which that source
+ * model re-injects for the scope that stores it. Without that
+ * re-injection the select would render its placeholder, the next admin
+ * save would post '' and the treatment guard would reject the whole
+ * section save.
+ *
+ * Scope-agnostic by construction: it rewrites `core_config_data` rows
+ * directly, matching `payment/<any brand code>/surcharge_tax_class` at
+ * every scope (default / websites / stores), because brand overlays
+ * save the same field under their own payment method code.
+ *
+ * The `tax_class` row itself is deliberately LEFT IN PLACE. Removing it
+ * is not FK-blocked once no config points at it (core's only foreign
+ * keys onto `tax_class.class_id` are `tax_calculation`'s two, and this
+ * class ships rule-free), but a product's tax class is an EAV attribute
+ * value with no FK at all — so a merchant who assigned the class to
+ * real products would get silently orphaned attribute values rather
+ * than an error. An orphan row that nothing references is cheaper than
+ * that risk. It is logged so an operator can remove it by hand.

Subject: [PATCH 137/885] feat(i18n): translate admin and buyer-facing __()
 strings
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Follow-up to TWO-25274, which closed the <comment>/<label> gaps in the
two admin XMLs. That work established that admin copy reaches the UI
through five different mechanisms and that an audit walking only the
XML sees one of them. This covers the remaining surface: __() literals
in PHP and .phtml with no row in any of the three catalogues.

Audited with a concatenation-aware extractor. PHP "." concatenation
inside __() is common here, and a naive regex truncates the msgid and
reports false gaps -- a naive scan claims 24 missing, but five of those
are truncation artefacts whose full concatenated msgid is already
translated. The real count is 17.

Adds all 17 to nl_NL, nb_NO and sv_SE, grouped by visibility:

Buyer-facing: the two "payment temporarily unavailable" variants, the
surcharge-cap-resolves-to-zero error, the payment-terms surcharge
calculation failure, and the "Surcharge" invoice PDF line label.

Admin: the surcharge tax treatment guard, the payment-term selection
guard, the cancellation sync failure, both invoice-upload outcomes,
the creditmemo refund label, the API key Merchant ID label, the
surcharge grid currency note, and the stale-assets deployment warning.

Diagnostic: the two Pricing API errors and the surcharge tax
calculation no-result error.

Deliberately NOT added: "Use Default Value" and "Use Website Value".
Those are Magento core's config inherit-checkbox labels, reused by
view/adminhtml/templates/system/config/field/surcharge-grid.phtml.
Core already ships all three locales, and Magento merges every module's
CSV into one dictionary per locale with no namespacing -- so adding our
own rows would shadow core across every module, not just ours.

Also drops a stale row keyed "Please select a surcharge tax treatment.
A surcharge method is enabled, so the surcharge tax treatment must be
chosen explicitly." -- the old, shorter, differently-capitalised
wording. The source string was later extended with the "(see the
Surcharge Method field)" clause and a new ending, so the row matched
nothing. Its target text is reused as the basis of the current wording.

Two machine-translation traps were caught while cross-checking, both
worth knowing about:

- Both engines render the brand name as the numeral -- "Twee
  betalingen" / "To betalinger" / "Två betalningar" for "Two payment
  is temporarily unavailable". The brand is preserved verbatim and the
  sentence recast as "Betalen met Two" / "Betaling med Two" /
  "Betalning med Two".
- Google Translate translated the CLI command, turning
  "run setup:static-content:deploy" into
  "voer setup:static-content:implement uit". The command, the
  buyer_fee_share field name and every %N are byte-exact.

Terminology follows each catalogue's own rows: surcharge =
toeslag/tillegg/tillägg, payment terms =
betaaltermijnen/betalingsvilkår/betalningsvillkor, tax = BTW/MVA/moms,
merchant = verkoper/forhandler/handlare, and the guard message reuses
the existing Surcharge Method and Surcharge Tax Treatment field labels
so it names the same words as the controls it points at.

Translations are AI-proposed and want a native reviewer.

Subject: [PATCH 138/885] fix(i18n): add Use Website Value and align
 terminology
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Review round 1.

The core-shadowing exclusion was half wrong. "Use Website Value" does
not exist in Magento core at all -- core's own config labels are
"Use Default" and "Use Website", and "Use Default Value" is core only
via product-form strings on a different surface. So there was nothing
to shadow, and the string rendered English at website scope in all
three locales. Added.

"Use Default Value" stays excluded, and does NOT need adding: Magento
merges every module's CSV into one dictionary per locale with no
namespacing, so core's own translation of that msgid already applies to
our template. Both labels now render translated, from different
sources.

Terminology aligned with existing catalogue rows, all found by the same
review:

- nb_NO used "kundestøtte" for support where the catalogue's own row
  uses "brukerstøtten" (see the order-cancellation row). Switched in
  all five new nb_NO rows.
- The surcharge cap was "tilleggstaket" / "tilläggstaket" while the
  same admin grid already renders its fixed fee limit as
  "avgiftsgrensen" / "avgiftsgränsen". Aligned. nl_NL already used
  "toeslaglimiet" in both places.
- "Amounts are shown in %1 unless otherwise stated." swaps with the
  existing "Amounts are shown in %1." in the same <p> via
  data-text-default / data-text-degraded, so the verb was visibly
  changing on toggle: nl_NL "weergegeven" -> "getoond" and nb_NO
  "Beløp vises" -> "Beløpet vises" to match their siblings. sv_SE
  already matched.

Two grammar corrections: nb_NO "ga ingen resultat" -> "ga ikke noe
resultat" (resultat is neuter, so "ingen" was the wrong gender), and
sv_SE "Handlar-ID:" -> "Handlare-ID:" ("handlar-" collides with the
present tense of "handla").

Translations are AI-proposed and want a native reviewer.

Subject: [PATCH 139/885] fix(i18n): match nl_NL inherit-label register,
 correct scope claim

Review round 2.

nl_NL "Use Website Value" was "Websitewaarde gebruiken" (infinitive).
The catalogue's own imperative register ("Kies", "Selecteer", "Voer")
and the effective nl language-pack rendering of the sibling
"Use Default Value" ("Gebruik standaard waarde") both take the
imperative, so this is now "Gebruik websitewaarde". nb_NO and sv_SE
already matched their packs' form.

Two corrections to statements made in d91ce3a, recorded here rather
than by rewriting pushed history:

1. That commit body and the PR body had the scopes the wrong way round.
   surcharge-grid.phtml:20 reads
   getScope() === 'stores' ? __('Use Website Value') : __('Use Default Value')
   so the untranslated label was showing at STORE-VIEW scope, not
   website scope.

2. "core's own translation already applies to our template" was too
   strong. Magento core ships en_US only; the localised
   "Use Default Value" comes from the separately-installed community
   language pack for each locale. The exclusion decision is still
   correct -- it does resolve wherever a pack is installed, and we must
   not shadow it -- but on a shop with no language pack that label
   renders English while our "Use Website Value" renders translated.

3. That commit body said "all five new nb_NO rows"; only four new
   nb_NO rows contain the support word.

Deliberately NOT changed, having checked the precedent: nl_NL
"Refund %1" stays "Terugbetaling %1" rather than adopting the
"Toeslagrestitutie" of the surcharge-refund validation rows. In
SurchargeOverride::getLabel() the %1 is the surcharge DESCRIPTION, not
an amount, so the string is a prefix ("Refund Partner Product - 30
days") and a different grammatical role from those rows. The sibling
fallback "Refund Two Surcharge" is already translated in all three
locales.

Translations are AI-proposed and want a native reviewer.

Subject: [PATCH 140/885] chore: bump version 2.2.0 -> 2.2.1

PR #293 landed on staging carrying 2.2.0, and the bump bot had put this
branch on the same 2.2.0. Two branches cannot ship the same version, so
this is the deliberate re-bump for the second of the pair.

Not a keep-both-sides resolution: the catalogues took both branches'
rows, but the version is a single value and had to be advanced rather
than merged.

Subject: [PATCH 141/885] TWO-25269/revert(surcharge): drop zero-cap
 fail-closed guard
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The guard added in #291 rested on a false premise. It threw a
LocalizedException whenever a configured surcharge limit resolved to
zero, on the belief that a zero cap read as "no cap" downstream and
would therefore relay an UNCAPPED percentage — an overcharge to the
buyer.

The pricing API does not behave that way. A zero cap CLAMPS the buyer
fee to zero; it never uncaps it, so no overcharge was possible. Only
an ABSENT limit means "no cap". A zero cap is a legitimate merchant
configuration meaning "apply no surcharge", and the plugin now relays
it unchanged.

Reverted:
- the `$cap <= 0.0` block, its error log and its LocalizedException;
  `cap` is assigned unconditionally for a non-null configured limit
- the comment prose asserting the uncapped/overcharge premise
- the `@throws` docblock additions covering the zero-cap case

Kept, being unrelated and correct:
- the no-FX-rate fail-closed error log and LocalizedException in
  convertAmount()
- the missing-buyer_fee_share and mismatched-currency error logs
- the `?int $selectedTermDays` parameter threaded into convertAmount()

No admin validation is reinstated: a typed `0` limit must save and be
relayed as `cap => 0.0`. A blank Limit cell already deletes the config
row, so absent and zero stay distinguishable at the storage layer.

Tests inverted accordingly, plus coverage that a zero cap needs no FX
rate cross-currency and rides alongside a converted fixed fee.
RepositoryPaymentTermsTest now asserts `limit` defaults to NULL rather
than 0.0, which previously passed only via PHP's loose null == 0.0.

Also records a known PRE-EXISTING gap, deliberately NOT fixed here:
convertAmount() returns unrounded figures, but the API rejects
monetary values finer than 2dp, so a cross-currency conversion
landing on >2dp fails the request. Any future fix must round a cap
away from zero, since a cap of 0.0 is now meaningful.

+## A surcharge cap of 0 is valid — never guard against it
+
+**A configured surcharge limit of `0` must be relayed to the pricing
+API as `cap => 0.0`. Do not throw, do not omit the key, and do not
+add admin validation rejecting a typed `0`.** A zero cap clamps the
+buyer fee to zero — no surcharge is applied — which is a legitimate
+merchant configuration.
+
+Only an *absent* (null) limit means "no cap"; that omits the `cap`
+key and applies the percentage uncapped. Absent and zero are
+different things and both must pass through faithfully.
+
+TWO-25269 briefly added a guard that threw on a zero cap, on the
+premise that a zero cap read as "no cap" downstream and would relay
+an uncapped percentage. **That premise was false and the guard was
+reverted** — a zero cap clamps the fee to zero, it never uncaps it.
+In `fixed_and_percentage` mode the cap bounds the combined fee, so
+`Limit = 0` suppresses the fixed component too, not just the
+percentage part.
+
+`Test/Unit/Service/Order/SurchargeCalculatorTest.php` pins this.

Subject: [PATCH 142/885] TWO-25279/fix(surcharge): anchor the never-taxed
 carve-out to the edited scope

Adversarial review round 1 found the carve-out read the wrong scope, so the
lockout it exists to prevent still fired. Proven on a live 2.4.6 install:
with `websites/1 = 0` and `stores/1 = 2` the website-scope form resolved
through the website's default store view, read 2, suppressed "None", rendered
the placeholder over the website's own stored 0, and the next save posted ''
and was rejected. A null store id has the same defect at default scope --
ScopeConfigInterface resolves it as the CURRENT store, not the default scope.

RepositoryInterface gains scope-explicit reads (hasCustomSurchargeTaxRateAtScope,
getSurchargeTaxClassIdAtScope) and the source model resolves
'store'/'website'/'default' from the admin scope params instead of collapsing
everything to a store view. Reads stay inheritance-aware -- a store view
showing an inherited "None" must still be offered it -- they are just anchored
one level at a time. The pre-existing "Custom" carve-out had the same defect
and moves to the same mechanism.

Also from the review:

- Server-side enforcement. Suppressing an option is a UI rule only, so
  beforeSave() now refuses a NEWLY submitted '0' at a scope that does not
  already store it, mirroring the sibling refusal of a hand-crafted 'custom'.
  A scope that already stores it can still resubmit, which is what keeps a
  pre-existing or migrated scope savable.
- Escape hatch. On a store with NO Product Tax Classes at all, suppressing
  "None" left the placeholder as the only option and the guard rejects the
  placeholder -- nothing selectable, no way back. "None" survives in that case.
- Guidance. The field had no <comment> and the PR removed the only zero-tax
  option the plugin shipped, so there was no in-admin signpost to the
  replacement route. Added, with nb_NO / nl_NL / sv_SE translations, as for
  the new guard message.
- Migration: the `_` in the config key were unescaped LIKE wildcards; the
  pattern now means the literal key (a surcharge_tax_rate decoy row proves it).
  The config cache is reinitialised after the rewrite, so a programmatic
  application does not leave the admin reading the pre-migration value. The
  class id is bound as a string even when the adapter returns an int.
- Tests: website-scope, default-scope and inheritance cases (their absence is
  what let the blocker through), the no-real-classes case, the exact LIKE
  pattern rather than "contains %", and a stale comment in SurchargeTest.

Subject: [PATCH 143/885] TWO-25279/fix(surcharge): make the option list and
 the save guard agree exactly

Adversarial review round 2 found round 1's own fixes had produced a new
BLOCKER: the "store has no Product Tax Classes" escape hatch offered '0' from
the option list while the new save guard refused it, so that store's only
selectable option could not be saved and the payment section was unsavable
either way. Proven live: options ["", "0"], real admin save of '0' rejected.

The hatch is removed rather than mirrored into the guard. Suppression is now
driven purely by the stored value on both sides, so the two can never offer
and accept different sets. A store with no Product Tax Classes disables the
Surcharge Method, saves, creates a Tax Rule and re-enables -- verified live
that this route saves cleanly.

Also from round 2:

- The guard compared the stored value as a raw string while the option source
  normalises numerically, so a stored '0.0' or ' 0' offered an option the save
  refused. Both now use the same normalisation.
- The brand-overlay form template carried no <comment>, so the only in-admin
  signpost to the replacement route existed on the base section alone.
- testStoredNoneCanBeResubmittedAtABrandScope could not fail for the reason it
  documented: the config stub ignored scope and scope id. It now asserts they
  reach ScopeConfigInterface.

Subject: [PATCH 144/885] TWO-25279/refactor(surcharge): enforce, do not
 grandfather

Scope cut: both live installations are already on standard tax, so the
accept-already-stored-values apparatus was protecting nobody and was where
every oscillation in the review loop happened. Removed wholesale.

Never-taxed treatments are simply absent from the dropdown -- core "None"
(class id 0) and the "Payment Terms Surcharge - No Tax" class the plugin used
to provision, the latter matched by name because its id is a merchant-side
auto-increment. No re-injection of a stored value, at any scope.

Instead, a scope still holding such a value FAILS LOUD:

- Block/Adminhtml/System/Config/Field/SurchargeTaxClass puts an error on the
  field naming the consequence and the way out (create a Tax Rule with a 0%
  rate, link to Tax Rules). Without it the failure looks like the opposite of
  what it is -- the select cannot render an absent value, so the field renders
  on the placeholder and merely looks unset while the surcharge is charged
  untaxed.
- the backend model refuses to save such a value, with no already-stored
  exemption, so a crafted POST cannot persist one either.

Model/Config/NeverTaxedTreatment is the single decision point the option
source, the renderer and the save guard all share. A scope warned about but
savable, or savable but not warned about, would each be worse than either
alone, so the rule is stated once.

Dropped with the grandfathering:

- the scope-explicit repository reads (hasCustomSurchargeTaxRateAtScope /
  getSurchargeTaxClassIdAtScope) and the resolveConfigScope() machinery. They
  existed only to decide whether to re-inject a stored value; nothing now
  reads config to build the option list, and the renderer reads
  $element->getValue(), which Magento has already resolved for the edited
  scope. This also removes the new public interface surface entirely.
- Setup/Patch/Data/MigrateSurchargeNoTaxSelections. It moved 0 rows on
  staging and both live installations are on standard tax, so it was a data
  migration with no data to migrate. Fail-loud covers the residual, and does
  it visibly rather than silently rewriting a merchant's tax configuration.

De-provisioning stays: SurchargeNoTaxClass is still removed, so no new
install grows a plugin-fabricated tax class.

Verified live on Magento 2.4.6 (11/11) after setup:upgrade + setup:di:compile:
both options absent from the dropdown, both refused at save, a stored value
NOT re-offered and NOT re-savable, and the loud comment rendered for both
never-taxed shapes but not for a real class.

+     * Two shapes, and both must be caught by VALUE or by NAME as

+     *  - the class the plugin used to provision has a merchant-specific
+     *    auto-increment id, so it can only be matched by its name.
      *
-     * Anchored to the scope, NOT to a representative store view. Resolving a
-     * website scope through its default store view reads the STORE row and
-     * so returns a deeper override — with `websites/1 = 0` and
-     * `stores/1 = 2` the website form would read 2, suppress "None", render
-     * the placeholder over a stored 0, and the next save would post '' and
-     * be rejected: exactly the lockout the carve-out exists to prevent.
-     * Likewise a store id of null does NOT mean default scope —
-     * ScopeConfigInterface resolves it as the CURRENT store — so the default
-     * scope has to be named explicitly.
+     * A merchant who happens to have named one of their own classes the
+     * same thing is also excluded, which is the safe direction: that name
+     * promises "no tax" and this plugin will not offer it as a treatment
+     * either way.
      *
-     * The reads stay inheritance-aware (a store view showing an inherited
-     * "None" must still offer it); they are merely anchored one level at a
-     * time rather than always at the bottom.

-/**
- * Retire the plugin-provisioned "Payment Terms Surcharge - No Tax"
- * Product Tax Class as a surcharge tax treatment (TWO-25279).
- *
- * That class was inserted into the merchant's own `tax_class` table by
- * a former data patch (Setup\Patch\Data\SurchargeNoTaxClass, removed in
- * the same change as this patch), deliberately rule-free so that
- * selecting it guaranteed an untaxed surcharge. That is exactly what
- * the plugin must NOT offer: it is a never-taxed treatment the plugin
- * fabricated, not a tax rule the merchant configured in Magento, and it
- * appeared in the merchant's Tax Rules UI as if they had created it.
- *
- * This patch repoints every stored selection of that class at core's
- * "None" (Product Tax Class id 0), which is the same never-taxed
- * behaviour expressed in a platform-native value — so no merchant's
- * checkout tax changes as a result of running it. Core "None" is itself
- * suppressed from NEW selections by SurchargeTaxClassSource; migrated
- * scopes therefore hold a stored-but-hidden value, which that source
- * model re-injects for the scope that stores it. Without that
- * re-injection the select would render its placeholder, the next admin
- * save would post '' and the treatment guard would reject the whole
- * section save.
- *
- * Scope-agnostic by construction: it rewrites `core_config_data` rows
- * directly, matching `payment/<any brand code>/surcharge_tax_class` at
- * every scope (default / websites / stores), because brand overlays
- * save the same field under their own payment method code.
- *
- * The `tax_class` row itself is deliberately LEFT IN PLACE. Removing it
- * is not FK-blocked once no config points at it (core's only foreign
- * keys onto `tax_class.class_id` are `tax_calculation`'s two, and this
- * class ships rule-free), but a product's tax class is an EAV attribute
- * value with no FK at all — so a merchant who assigned the class to
- * real products would get silently orphaned attribute values rather
- * than an error. An orphan row that nothing references is cheaper than
- * that risk. It is logged so an operator can remove it by hand.

Subject: [PATCH 145/885] TWO-25288/feat(checkout): make the address-step
 company number usable
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The address step already carried a `company_id` field, declared
invisible, while the payment tile carried a second, visible copy — the
only one of the four checkout surfaces with two buyer-facing company
fields. Render the address-step field and give it the capabilities the
tile's copy has, so it can become the single company surface.

- Layout: the field renders, and arrives disabled. Company search fills
  it from the registry for a picked company, so an editable field would
  only let the buyer contradict the registry. Label matches the tile's
  ("Company Number"), which is already translated in every shipped CSV.
- Storefront JS derives the editable state the same way the tile does —
  editable exactly when a company is in play with no registry identifier
  behind it — and publishes what the buyer types so it reaches the
  payment step.
- Publishing keeps ONE writer of the `companyData` customer-data
  section: `publishCompanyData()` is now the sole call site, and the
  payment step's reading of a change notification as an act of selection
  depends on that. The derivation is deliberately not re-run from the
  company-number field's own change handler, which would disable the
  field the instant the buyer finished typing into it, and the publish
  is bound to `change` rather than `keyup` because the payment step
  fires an order intent as soon as it holds both a name and a number.

Purely additive: nothing is removed, and the payment tile behaves as
before. Removing the tile's copy is the follow-up.

+ *
+ * TWO-25288, first half. The address step gains a usable company-number
+ * field, so that it can become the single company surface on Luma. What is
+ * pinned here:
+ *
+ *  - the field is editable exactly when a company is in play with no registry
+ *    identifier behind it (the derivation the payment tile already applies to
+ *    its own copy of the field), and
+ *  - whatever the buyer types into it reaches the payment step through the ONE
+ *    writer of the `companyData` customer-data section, because the payment
+ *    step reads a change notification on that section as an act of selection.
+ *
+ * LIMITATIONS OF THE DOUBLES BELOW — read before trusting a pass here.
+ *
+ *  1. `node.on()` keeps ONE handler per event name and `off()` is a no-op, so
+ *     nothing here can speak to handler ordering or coexistence.
+ *  2. The AMD harness's sandbox `document` has no `querySelector`, so the
+ *     `select2:open` handler (which calls it) cannot be driven. The
+ *     "Enter details manually" affordance is therefore exercised through
+ *     `setCompanyData()` — what that handler calls — and not through the click
+ *     itself. A regression that unwired the click would NOT fail here.
+ *  3. The shared harness mocks `Two_Gateway/js/model/company-search` to a set
+ *     of no-ops (`buildSearchAjaxOptions` returns `{}`, `lookupCompanyAddress`
+ *     returns null). Nothing in this file covers real search behaviour, and a
+ *     test that loaded the module and asserted on search results would be
+ *     asserting against those stubs.

Subject: [PATCH 146/885] feat(company-search): TWO-25288 pure-CSS
 radial-spokes spinner
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Replace the company-search dot-pulse loader with a radial-spokes
indicator drawn entirely in CSS. The spinner element becomes a single
childless span, so there is no inner markup to keep in sync with the
stylesheet.

Notes on two traps the implementation has to avoid:

- The rule stays a single flat class selector. Brand overlays recolour
  this indicator from their own stylesheet with flat single-class rules
  and win on load order alone, so qualifying the selector would outscore
  them and silently break branded recolouring with nothing failing in
  CI. The colour hook is `--two-spinner-color`, falling back to the
  inherited text colour, which is what those overrides already set.
- Vertical centring uses a negative margin, not `translateY(-50%)`. The
  spin animation owns `transform`, so a translate here would be
  overwritten mid-animation and drop the spinner half its own height out
  of the field.

The element keeps its existing single class and `aria-hidden="true"`.
The payment-term chip loader and its `two-term-chip-dot` keyframes are
untouched — the chip template still uses them.

Subject: [PATCH 147/885] fix(company-search): TWO-25288 rotate the spinner
 continuously
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

`steps(12, end)` over `1turn` advances the ring in exactly 30deg
increments, and the spoke pattern has a 30deg period — so every step
maps the pattern onto itself and the spinner renders motionless. Same
holds for any step count whose increment is a multiple of the period.

Use a continuous linear rotation instead and record the reasoning, so
the tick-style timing function does not get reinstated.

Geometric, not visually verified in a browser.

Subject: [PATCH 148/885] test(company-search): TWO-25288 pin the spinner path
 on both surfaces
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Both Luma company pickers drive the spinner through the shared search
model, which makes it tempting to assume that model-level coverage
proves both surfaces work. It does not: each surface wires its own
`onSearching` callback and stamps its own bind token, so a surface whose
wiring exists but never reaches markup would render no spinner at all
while every existing test stayed green. The default AMD harness stubs
`setSearching` to a no-op, so nothing covered this path.

Loads the real search model into each real surface module, calls
enableCompanySearch(), then drives the real select2 transport the surface
built — the thing that fires onSearching internally — and asserts the
spinner element lands in select2's search box, childless and aria-hidden.

Verified by mutation: severing one surface's setSearching call reddens
only that surface, and giving one surface's markSearchBinding a different
token than its ajax options reddens only that surface.

Subject: [PATCH 149/885] feat(company-search): TWO-25288 draw the spinner from
 the loading GIF
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The in-field company-search spinner is now the same loading GIF the
PrestaShop plugin already ships, painted as a background-image on the
existing childless span.

The previous attempt drew the indicator in CSS from a masked
repeating-conic-gradient rotated by a keyframe animation. That produced
a provably motionless indicator, and the paint was fragile enough that
it is not worth a second attempt: an animated GIF is a single 1553-byte
asset that cannot stop moving.

Replaced, in view/frontend/web/css/style.css:

- the gradient background, the mask pair, the border-radius, the em
  sizing and the rotation keyframes are all gone
- so is the prefers-reduced-motion rule. CSS cannot pause, slow or step
  an animated GIF, so such a rule would be a literal no-op that
  misleads the next reader
- sizing is a fixed 16px, matching the asset's native dimensions;
  scaling it up only blurs it

The URL is a stylesheet-relative background-image rather than an <img>
tag on purpose: static content deploy publishes css/ and images/ side
by side under the module's directory, so url("../images/…") resolves
with no asset helper plumbed through the markup.

The payment-term chips' three-dot keyframes are untouched — the chips
still use them.

Subject: [PATCH 150/885] test(company-search): TWO-25288 pin the spinner asset
 resolution
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Nothing previously asserted that the spinner's figure resolves at all.
Two independent regressions are invisible from the DOM: the
background-image declaration can be dropped from the rule, and the URL
can be repointed at a path that holds no asset.

The new suite injects the real stylesheet into jsdom, puts a node
carrying the spinner class in the document, and asserts on the computed
style — so a rule that parses but is dead fails. The disk check
resolves whatever URL the stylesheet actually declares rather than a
hardcoded path, so repointing the URL fails even when the old file is
still present.

background-position is deliberately not asserted on: jsdom does not
resolve the multi-value shorthand form and reports it empty even when
the rule is correct.

Verified by mutation — each of these turns the suite red: repointing
the url() at a nonexistent filename, deleting the background-image
declaration, deleting the asset, renaming the selector class, and
reverting the sizing to em.

Subject: [PATCH 151/885] docs(company-search): TWO-25288 correct the spinner
 override rationale

The comment claimed brand overlays recolour the indicator. Since the
spinner became a background-image GIF the rule declares no `color` at
all, so nothing can be recoloured. Restate the actual reason the
selector must stay a single flat class: overlays override it at equal
specificity and win on load order alone.

Comment-only; no assertion changed.

A comment in the e2e helpers pointed at an internal repository's
internals to explain where a test fixture value comes from. Replaced
with a description of what the value is and how to override it.

Comment text only; nothing reads it.

Subject: [PATCH 153/885] feat(TWO-25288): refuse placement when company number
 is empty
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The only thing preventing an order with an empty company number was a
client-side validator on the checkout field. Any storefront that does
not render that field, or any client that skips it, reached the order
request with an empty value and was refused only after placement had
already begun.

Add a server-side floor on the payment method's authorize() path, ahead
of composing the order request, so the buyer gets a specific message and
no order is created in a broken state. Whitespace counts as empty.

authorize() is the single decision point every storefront's placement
runs through, so no checkout variant can diverge from another. The
client-side validator is untouched — it remains the good UX path and
this is the floor beneath it.

Subject: [PATCH 154/885] feat(company-search): TWO-25288 own the
 below-threshold search hint
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Luma's company pickers fell through to select2's own built-in "input
too short" text. That text lives inside the vendored bundle, so it is
hard-coded English that no translation dictionary can reach, and it is
phrased as a countdown of the REMAINING characters rather than naming
the threshold.

Override it via select2's `language.inputTooShort` on the address-step
picker with a plugin-owned translatable string that quotes a fixed
number. The vendored bundle is not modified.

The number is interpolated from the shared minimum-length constant, and
both pickers now read that constant for `minimumInputLength` instead of
repeating a literal — so the number the hint claims and the number
select2 enforces cannot drift apart.

The empty-field hint on the address step was already in place and is
unchanged; it is now pinned by tests.

Subject: [PATCH 155/885] docs(TWO-25288): correct min-chars hint docblocks and
 test framing

The minInputLengthMessage() docblock claimed all call sites override
select2's inputTooShort. Only the address-step picker does; the
payment-step picker passes minimumInputLength alone and still renders
select2's vendored English remaining-count text. Say so plainly and
mark it out of scope rather than implying parity that does not exist.

Also drop the hard-coded threshold from three prose comments that
quoted the rendered hint verbatim, and derive the shared test harness
mock's message from its own MIN_INPUT_LENGTH so the harness every JS
suite consumes stops reintroducing the literal.

Test framing: the empty-field placeholder hint pre-dates this change,
so relabel those cases as regression pins instead of implying they
cover new behaviour. Replace a vacuous assertion on the vendored
bundle (upstream never had the placeholder form, so its absence could
not fail) with one pinning upstream's own inputTooShort implementation
verbatim.

No runtime behaviour changes.

Subject: [PATCH 156/885] test(TWO-25288): pin the guard call site's argument,
 not just its order
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The wiring test asserted only that the guard call appears before the
order request is composed. A call handed the wrong array — an empty
literal, say — satisfies that and refuses every order while the whole
suite stays green. Pin the argument expression as well.

Also correct the guard's docblock: it trims to decide, but normalises
nothing, so a padded non-empty company number clears the guard and
ships padded. Behaviour unchanged; the comment now says so.

preg_match stops at the first match, so the assertion message's
'exactly once' claim was not what the code checked. Count with
preg_match_all instead.

Subject: [PATCH 158/885] TWO-25288/fix(checkout): gate the address
 company-number field on an active method
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The field became `visible`, so a store that merely has the module
installed with the payment method switched off would render a
company-number input on the address step for every buyer. Early-return
the layout untouched unless the method is active, matching how the
payment-method list plugin gates its own append.

Also pass the label and tooltip through `__()` — the catalogue rows
already exist, and a now-visible label would otherwise ship
untranslated; the label assertions now compare a cast string rather
than cementing the untranslated form.

The unit test seeded `[]` as its `jsLayout`, which autovivified the
whole path and left it only re-reading what the plugin had just
written. It now seeds the real shipping-address fieldset with a sibling
field and asserts the node landed in that pre-existing node, so a
drifted path fails.

Subject: [PATCH 159/885] TWO-25288/fix(checkout): stop the company-name
 handler locking a typed-in number
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

In manual mode, a buyer who typed the company number and then went back
to edit the company NAME hit the name handler's full re-derivation.
That derivation reads the number field's value, which is non-empty by
then, so it disabled the field — locking the buyer out of the number
they had just typed, with nothing clearing it. The name handler is now
enable-only; only the paths that can learn a number from the registry
may disable.

Toggle the state through the UI component as well as the DOM. The
layout declares `disabled` as a component property and the input
template binds it inside a compound `attr:` binding, so any
re-evaluation of that binding reinstates the component's stale value
over a raw `prop()` write.

Three comments corrected while in here: the claimed `required` rule
does not exist on this field (it declares no required-entry rule,
unlike the payment tile's own copy), and the picker does not replace
the name input's value with an internal item id — the name is written
there.

Subject: [PATCH 160/885] refactor(TWO-25288): drop the hand-typed company
 number from the payment tile

The payment tile carried an always-visible, always-editable
organisation-number input. Hand-typed identifiers are not an accepted
source: they produce poor data quality and, worse, genuine buyers
receive invoices for orders they never placed. Remove the input.

The value never needed a DOM carrier. `companyId()` is written only by
a company-search pick, the sole-trader autofill response, or the
address step's `companyData` notification, and getData() reads the
observable, not the field.

Dead machinery removed with it, rather than left bound to nothing:

  - `companyIdSelector`, and the `$.async` block in
    enableCompanySearch() that resolved it
  - `needsManualCompanyId()` and `syncCompanyIdEditable()`, whose only
    effect was that field's `disabled` state
  - `_companyIdEditableSubs` and its dispose() branch, created only
    inside the removed `$.async` block
  - `clearCompany()`'s `disableCompanyId` parameter
  - the `$(companyIdSelector).val()` display writes in
    fillCompanyData() and selectCompanyWithoutIdentifier()

The identically-named symbols in address-autocomplete.js belong to the
ADDRESS step's field and are deliberately untouched.

Nothing client-side now enforces a non-empty organisation number.
Model/Two.php::authorize() refuses such an order server-side and is the
sole enforcement.

Subject: [PATCH 161/885] test(TWO-25288): pin the tile company-number removal
 and the sole-trader path
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

New Test/Js/tile-company-number-removed.test.js covers both halves:

  - the markup offers no number field, still offers the required name
    field, and the renderer retains no apparatus for the removed input
    (companyIdSelector / needsManualCompanyId / syncCompanyIdEditable
    all gone, clearCompany down to zero arguments);
  - an accepted organisation number still reaches getData(), which is
    the real submit path — including the sole-trader synthetic number,
    the one value that is minted rather than picked and so the one most
    likely to break silently.

The DOM assertions use a RECORDING jQuery double rather than the default
harness one: the default reports `length: 0` and returns the same inert
object from every setter, so it cannot tell a write from no write.
`company_name` writes are asserted alongside the absent `company_id`
writes so an inert double cannot be what makes the test pass.

Existing tests: the company_id editability describe block is deleted
outright — its subject no longer exists — and the DOM value/disabled
assertions elsewhere are reduced to the observable assertions that still
mean something. Stale `companyIdSelector` entries in three renderer-context
fixtures removed so no fixture describes a field that is gone.

Subject: [PATCH 162/885] test(TWO-25288): cover the chip-click sole-trader
 route and fix a test that could not fail

Mutation testing found two defects in the previous commit's tests:

  - the clearCompany assertion used Function.length, which a default
    parameter does not affect, so restoring `disableCompanyId = false`
    left it green. Assert on the function's own source instead.
  - only applyPrefetch() was covered; soleTraderMode() is a separate
    call site for a minted organisation number and survived its
    mutation. Cover it.

Documentation (comments describing code this PR removed):
  - address-autocomplete.js claimed parity with a payment-tile
    derivation that no longer exists
  - company-search.js told the reader an empty identifier makes the
    payment step re-enable a field it no longer has, and named the two
    deleted functions
  - the new applyCompanyData() docblock listed getData()/placeOrderIntent()
    as the only readers of companyId(); the authoritative guard and the
    notice subscription read it too
  - the new template comment named two sources as exhaustive, then
    referred to a third; there are three

Tests:
  - RESTORED LOST COVERAGE: deleting the editability describe block took
    with it the only test anywhere for updateAddress()'s company_id
    custom-attribute parsing, whose subject is still live. That block
    mixed a dead assertion (field disabled state) with a live one
    (companyId observable); only the former was dead.
  - three assertions restated an observable's declared initial value and
    could not fail; two replaced with the assertion that can, one test
    deleted as a duplicate of its predecessor
  - the markup assertions matched fixed substrings, so a single-quoted
    or ko-attr-bound reinstatement would slip through; now regex-based
  - the required-input count honoured only `required="true"`; now counts
    every spelling jQuery Validation honours, and checks the surviving
    tag IS the name field rather than merely preceding the first match
  - the file header oversold the accepted-source tests as pinning the
    removal; they pass pre-change and are labelled as regression pins

Round 2 confirmed the round-1 fixes sound and introduced no new defect.
These are further pre-existing misses it surfaced.

Docs:
  - the writer list for companyId() was still one short. updateAddress()
    parses a company_id custom attribute off the quote's billing/shipping
    address and writes the observable, which fires from the quote
    subscriptions with no address-step interaction at all — a saved
    customer address carrying the attribute is enough. Enumerated
    properly, and the template comment now points at that list instead
    of keeping its own divergent count.

Tests:
  - 'an identifier-less pick places no intent' could not fail for the
    regression it names: an intent is placed only after
    fillCompanyData()'s empty-id guard, and selectCompanyWithoutIdentifier()
    places none either, so no routing choice placed one. Seeds a real
    company first so the intent COUNT discriminates the two routes, and
    asserts the previous identifier was cleared.
  - String(renderer.clearCompany) passed vacuously if clearCompany were
    renamed or deleted, String(undefined) containing none of the
    forbidden substrings. Subject guarded first.
  - the broad not.toMatch(/company_id/) over the whole template both
    subsumed the two narrower regexes and would fail for a legitimate
    future reference such as a for="company_id" label. Scoped to
    <input> tags.
  - stale fixture comment claiming enableCompanySearch() derives editable
    state from the companyName observable.

Subject: [PATCH 165/885] docs(TWO-25288): finish the writer-count sweep into
 the test comments
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Round 3 verdict was ready-to-merge with no oscillation; these are the
residual comment inaccuracies it found, all in text this PR wrote.

  - two test comments still enumerated three accepted sources, the same
    under-count already corrected in the renderer docblock and the
    template. Both now defer to the enumeration on applyCompanyData()
    instead of keeping a third copy — that list has drifted twice, so
    restating it is the actual defect.
  - the restored updateAddress() test now says plainly that its subject
    is the writer path most easily conflated with the `companyData`
    notification, and that it fires from the quote subscriptions with no
    address-step interaction.
  - the file header claimed every accepted-source test passes pre-change.
    One does not: 'the sole-trader number survives with no number input
    in the DOM' asserts no writes to input#company_id, and pre-change
    fillCompanyData() wrote it. Confirmed by mutation M4, which turned
    that test red. It is a removal pin and is now labelled as one.

Comment-only; no production or assertion behaviour changed.

Subject: [PATCH 166/885] feat(company-search): TWO-25288 manual-entry row
 inside the address-step results list
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The address step offered manual entry as a bare div appended NEXT TO the
results list rather than into it, so it sat outside the listbox the combobox
owns: no arrow key reached it and no screen reader announced it. It was also
shown whenever the dropdown opened, regardless of what had been typed.

Replace it with "My company is not on the list" as the last row inside the
results list — a real option row carrying the class the bundled select2 walks
for keyboard navigation, role=option, and a payload whose id and result id are
what select2 stringifies and what aria-activedescendant points at. The row
appears on input as soon as the term reaches the shared threshold, ahead of the
debounced request, and is re-appended after each render because select2 empties
the list on every result set. Activation is intercepted on the preventable
pre-selection event, so the sentinel never reaches the code that treats a
selection as a company.

The reusable pieces live in the shared search model beside the other chrome
helpers, on their own event namespace so their off()/on() cannot unbind the
below-threshold cancel handler on the same node.

Refs TWO-25288 element 5.

+ * TWO-25288 element 5. The manual-entry affordance on the address step.
+ *
+ * What changed, and therefore what these tests have to hold down:
+ *  - it is now the LAST ROW INSIDE the results list, not a div appended
+ *    outside it. That is the whole accessibility fix: outside the list it sat
+ *    outside the listbox the combobox owns, so no key reached it and no
+ *    screen reader announced it;
+ *  - it appears as soon as the term reaches the shared threshold, on `input`,
+ *    ahead of the debounced request — the buyer whose company is not in the
+ *    registry must not have to wait out a search that cannot help them;
+ *  - it survives every re-render, because select2 empties the list on each
+ *    new result set;
+ *  - activating it is intercepted and cancelled, so the sentinel row never
+ *    reaches the code that treats a selection as a company.
+ *
+ * Mutation-resistance notes, because this repo's harness makes vacuous
+ * assertions easy:
+ *  - the model DOM tests run against REAL jsdom nodes through a small
+ *    jQuery-lite double, so `length`, class lists, attributes and sibling
+ *    order are the document's answers, not a stub's;
+ *  - the threshold is injected DELIBERATELY WRONG (5). Asserting against 3
+ *    would pass whether the source read the shared constant or kept a
+ *    literal;
+ *  - translation is asserted on the msgid, since `$t` resolves to identity
+ *    here;
+ *  - the surface tests assert the picker actually bound select2 before
+ *    asserting anything about its handlers.

Subject: [PATCH 167/885] fix(company-search): TWO-25288 round-1 review fixes
 on the manual-entry row

- drop the `data-selected` attribute and its docblock clause: the vendored
  bundle contains no such attribute, so writing one was a misleading claim
  about what select2 reads. The `--selected`-class half stands.
- drop the payload's `html` field. The only consumer writes it through
  innerHTML after this picker's identity escaper, which would undo the
  deliberate `.text()` write.
- exclude nested group lists from the results-list lookup. Unreachable while
  results are flat, but grouping would otherwise put a row in every group.
- make the row's constants and label helper private, matching how this file
  already treats its other chrome constants; the tests re-declare the
  literals rather than reading them back.
- cancel the in-flight search when the row is activated. The selection is
  prevented, so the dropdown stays open and a late response would otherwise
  run the picker's highlight and scroll bookkeeping over a torn-down widget.
- stop watching the results list on close as well as re-attaching on open, so
  a form re-rendered while the picker is closed cannot leave an observer
  pinning a detached list.
- correct two stale premises in the company-number field's test header: the
  harness sandbox now has a querySelector, and the affordance it describes is
  no longer click-driven.

Tests: assert the results-list lookup's staleness guard directly (the
search-box guard was keeping it green on its own), pin the row id to the list
it belongs to, canary the two bundle internals the row depends on, read the
catalogue list off disk, and cover both new behaviours.

Refs TWO-25288 element 5.

Subject: [PATCH 169/885] test(company-search): TWO-25288 close two vacuity
 gaps in the manual-entry suite

The stale-bind assertion expected an empty list where the list was already
empty, so it could pass without the guard it names doing anything. It now
paints the row with a live bind first, then re-runs the same call after the
bind has been superseded. The two remaining empty-after assertions are labelled
for what they are: one precondition, one falsifiable-by-always-show.

Subject: [PATCH 172/885] fix(company-search): TWO-25288 round-2 review fixes
 on the manual-entry row

- pin the bind token threaded into the row's two closures. The direct helpers
  were covered; the input handler and the observer callback were not, and a
  closure that read the node's identity instead of its own token would match
  the NEW bind after a form re-render and paint onto the live picker. The new
  case asserts the row paints while the bind is live first, so the
  zero-assertions after the re-render cannot pass vacuously.
- widen the bundle canary to the previous-result handler and the mouseup
  delegate: it claimed arrow-key navigation while pinning arrow-down only, and
  the class occurs eight times in the bundle.
- correct the payload-id docblock. The bundle does not throw without an id; the
  stringification yields the literal "undefined" and the row is then compared
  under that, so it matches any other id-less row. The field is still required.
  The mirrored claim in the test comment is corrected too.
- drop the deleted affordance's fixture props from the four neighbouring suites'
  shipping contexts. The billing copies stay: the payment tile still renders
  that string.

Subject: [PATCH 173/885] test(company-search): TWO-25288 pin attach's own
 bail-out on a stale bind
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The surviving mutation was attach reading the node's bind identity instead of
the token it was handed. The consequence is not a stray row — every render it
wires is gated by that same stale token — it is that it disconnects the LIVE
bind's observer on its way past and replaces it with an inert one, so the live
picker silently stops re-appending its row.

 read no test can falsify

The term lookup inside renderManualEntryRow is handed the same token for
consistency, but the results-list lookup above has already refused a stale
bind, so no test can tell that argument from the node's own identity. Said
plainly in the source rather than left looking like covered behaviour.

Subject: [PATCH 175/885] fix(company-search): TWO-25288 bound the manual-entry
 observer against its own idempotency check
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Review round 1 finding 5: the mutation-observe-render loop that keeps the
manual-entry row's position current relied solely on an is(':last-child')
check to avoid re-appending itself. A broken check turns the row's own
append into a mutation the observer watches, recursing forever as
microtasks — nothing macrotask-scheduled ever gets a turn, so the tab
locks up rather than throwing. Disconnect the observer for the duration of
our own write and reconnect after, so a self-caused mutation can never
re-trigger the callback regardless of whether the idempotency check holds.

Subject: [PATCH 176/885] test(company-search): TWO-25288 pin the manual-entry
 row's dead-code-safe lines

Review round 1 findings 1-4: four lines in attachManualEntryRow /
enterDetailsManually were deletable without any test noticing.

- attachManualEntryRow's detachManualEntryObserver() call (before creating
  a fresh observer) and its final direct render() call each lacked a test
  that could tell their absence from a bind that just hadn't fired an
  input event yet. Added: attach-before-typing (proves the direct render
  call), and a render-spy across a re-attach (proves the observer isn't
  duplicated).
- enterDetailsManually's `.off(EVENT_NS)` and `.val('')` calls on the
  address-step surface were never asserted at all; the surface mock did
  not record either. Instrumented the mock and asserted both, counting
  from immediately before activation so the assertions cannot pass on
  enableCompanySearch's own unrelated rebind-clear off() call.

All four verified by reverting to HEAD~1's line, confirming red, then
restoring.

Subject: [PATCH 177/885] fix(company-search): move payment-tile manual-entry
 affordance inside the results listbox
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The payment-tile company picker rendered "Enter details manually" as a
footer div outside the select2 results list, sitting outside the
combobox's aria-owns — unreachable by keyboard and unannounced to a
screen reader. Same defect class as the address-step picker, now
diverged between the two.

Adds the manual-entry row as a real, accessible select2 option to the
shared company-search model (attachManualEntryRow / renderManualEntryRow
/ isManualEntryOption / detachManualEntryObserver) and wires the
payment-tile picker to it via select2:open / select2:selecting /
select2:close, removing the old outside-the-listbox div and its click
handler.

+/**
+ * Copyright © Two.inc All rights reserved.
+ * See COPYING.txt for license details.
+ *
+ * Item follow-up from PR #305 (address-step manual-entry affordance): the
+ * payment-tile company picker (`gateway_method.js`) still rendered its own
+ * manual-entry affordance OUTSIDE the select2 results listbox — the same
+ * accessibility defect #305 fixed on the address step, now diverged between
+ * the two pickers. This file pins the shared-model fix and the payment-tile
+ * surface's use of it.
+ *
+ * Load-bearing guarantees:
+ *  - the manual-entry row is a REAL row INSIDE the results list (`<li>`,
+ *    `role="option"`, `--selectable`, matching `aria-activedescendant`
+ *    plumbing via `_resultId`), not a footer div outside it. Outside the
+ *    list it sits outside the combobox's `aria-owns`, so no key reaches it
+ *    and no screen reader announces it;
+ *  - it appears at the shared MIN_INPUT_LENGTH threshold and survives a
+ *    result-list re-render (select2 empties the list on every new page of
+ *    results);
+ *  - a stale bind token can never paint a row onto a widget it doesn't own;
+ *  - the payment-tile surface (`gateway_method.js`) wires the model's
+ *    `attachManualEntryRow` / `detachManualEntryObserver` and intercepts
+ *    `select2:selecting` for the sentinel row, and no longer builds the old
+ *    outside-the-listbox div.
+ *
+ * Mutation-resistance notes:
+ *  - the model tests run against REAL jsdom nodes through a small
+ *    jQuery-lite double, so `length`, class lists, attributes and sibling
+ *    order are the document's answers, not a stub's;
+ *  - the threshold is exercised at MIN_INPUT_LENGTH - 1 and MIN_INPUT_LENGTH
+ *    read off the module's own exported constant, so a literal "3" drifting
+ *    from the real constant would still be caught structurally (the row's
+ *    presence/absence is asserted against the module's threshold, not a
+ *    hardcoded number);
+ *  - translation is asserted on the msgid, since `$t` resolves to identity
+ *    here;
+ *  - the surface test greps the real gateway_method.js source, so deleting
+ *    the wiring (reverting to the old div) fails it directly.

Subject: [PATCH 178/885] fix(company-search): close two teardown gaps in the
 payment-tile manual-entry row
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Adversarial review round 1 (Han) found two real gaps:

- the observer created by attachManualEntryRow() was only disconnected
  on select2:close/dispose, not on the re-bind path enableCompanySearch()
  takes on every re-render — a re-render while the picker is open can
  replace the select2 instance without emitting select2:close first,
  orphaning the previous observer's detached results list.
- clearCompany() tore the select2 instance down synchronously from
  inside select2's own select2:selecting dispatch; deferred the
  teardown a tick so select2's own post-preventDefault bookkeeping for
  that event finishes first.

Tests pin both: the re-bind path now asserted to call
detachManualEntryObserver before re-init, and the selecting handler
asserted to defer clearCompany() via setTimeout rather than call it
inline.

Subject: [PATCH 179/885] feat(TWO-25288): grey inline company-id hint,
 CSS-hide address-step field
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Ports the reference company-search UX: the payment tile's company-name
field now shows the selected company's registry id in light-grey text to
its right, cleared with the companyId observable. Cosmetic only — getData()
keeps reading companyId() directly, nothing new writes it.

Also hides the address step's separate "Company Number" field purely via
CSS (new .two-company-id-hidden class), rather than flipping its
`visible` config to false: address-autocomplete.js resolves the field
through uiRegistry.get(), which a visible:false would remove from the
registry entirely. The DOM node and its submitted value are unaffected.

Review flagged that the comment described the address-step fix as
already landed; #305 is still open/unmerged. Reworded to reflect that
this PR tackles the payment-tile picker independently.

Subject: [PATCH 181/885] feat(TWO-25288): open and focus company search on
 return from manual entry
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The "Search for company" link only re-bound the picker and hid itself,
leaving the buyer on a closed dropdown they had to click a second time
before they could type. It now asks the fresh widget to open, which runs
the existing `select2:open` handler and puts the caret in the search box.

The request is a one-shot local, not a component flag: the bind runs
inside a `$.async` MutationObserver that fires again on every re-render,
so a persistent flag would pop the dropdown open under a buyer who has
moved on. The initial render passes no option and is unchanged.

Test/Js/company-search-return-to-search.test.js drives the real journey
on both pickers and asserts the real DOM — an open container, one live
`.select2-search__field`, and `document.activeElement` being that input.
The select2 double throws on `open` without an instance, so opening
before the re-bind cannot pass. amd-harness gains an optional globals
argument so the module can see jsdom's document instead of the inert stub.

+ * TWO-25288. Returning from manual company entry to search mode.
+ *
+ * Both pickers grow a "Search for company" link once the buyer has taken the
+ * "Enter details manually" exit. Clicking it used to only re-bind select2 and
+ * hide itself, leaving the buyer looking at a CLOSED picker they had to click
+ * a second time before they could type. This pins that the link now opens the
+ * dropdown and lands the caret in the search box.
+ *
+ * Mutation-resistance notes, because this repo's AMD harness makes vacuous
+ * assertions easy to write:
+ *
+ *  - The assertions are on the REAL jsdom DOM, not on call records:
+ *    `document.activeElement` and the presence of an open container /
+ *    search input. `toHaveBeenCalledWith` on a select2 spy would pass for an
+ *    implementation that opened a dropdown nothing could type into.
+ *  - The jQuery and select2 doubles are DOM-backed: `select2('open')` really
+ *    attaches a dropdown containing a real `<input class="select2-search__field">`
+ *    and really marks the container open, so the production
+ *    `document.querySelector('.select2-search__field').focus()` has to run
+ *    against a live node for the focus assertion to pass.
+ *  - `select2('open')` on a destroyed/absent widget THROWS in the double, as
+ *    it does in select2 4.1. Opening before the re-bind cannot pass.
+ *  - Every case first drives the real journey (open picker → manual entry →
+ *    click the link) and asserts the pre-click state is closed and unfocused.
+ *    A surface that never bound the link would fail there rather than
+ *    presenting as green. The two surfaces offer manual entry differently —
+ *    a cancellable results row on the shipping step, a link below the results
+ *    on the payment step — so each drives its own production route.
+ *  - Two negative pins guard the obvious over-reach: the FIRST bind (initial
+ *    checkout render) must not open anything, and a later `$.async` re-fire
+ *    must not re-open it under a buyer who has moved on.

Subject: [PATCH 182/885] TWO-25289/fix(surcharge): refuse a limit of 0 in the
 surcharge grid

A limit of exactly 0 survived the grid: validateValue only rejected
negatives, and only an empty cell deleted the config row. Zero is
never what an admin means by it.

The limit bounds the WHOLE fee line - the percentage part and the
fixed amount together, not the percentage alone - so a limit of 0
silently wipes a configured fixed amount too, with nothing in the
admin copy saying so. And the intent it gets mistaken for ("charge
nothing on this term") is already expressible directly, by entering 0
in the fixed and percentage cells.

So: refuse it at entry, and say what to do instead. An EMPTY limit
stays valid and still means "no limit" - absence and zero are
different values, and only the explicit zero is refused.

- Model/Config/Backend/SurchargeGrid: reject `limit` === 0 (the
  authority; reachable from the admin UI, from `config:set`, and from
  app:config:import alike).
- surcharge-grid.phtml / surcharge-grid.js: the same refusal in the
  browser, as a registered rule rather than Magento's own
  validate-greater-than-zero, which is locale-blind - parseFloat('0,5')
  is 0 for a Dutch admin and would reject a legitimate half-unit
  limit. Applied to rendered rows and to rows the JS adds live.
- Admin copy: state that a limit of 0 is not allowed, and - on
  fixed_and_percentage, the only mode where it is load-bearing - that
  the limit applies to the whole fee rather than the percentage alone.

Tests: the pre-existing SurchargeGridTestable stub reimplements the
save flow, so it cannot pin a validation RULE - breaking the
production check could not turn a stub-only test red. The three new
tests therefore invoke the production validateValue directly.
Verified by mutation: neutering the check reddens
testProductionValidatorRefusesAZeroLimit only; widening it to `>= 0`
reddens testProductionValidatorAcceptsAPositiveLimit. Three existing
fixtures carried `'limit' => '0'` incidentally and would have started
passing for the wrong reason - emptied.

Refs TWO-25289.

Subject: [PATCH 183/885] TWO-25289/chore(i18n): translate the zero-limit
 strings (nb_NO, nl_NL, sv_SE)

Append-only, kept as its own commit so it rebases cleanly behind the
other i18n work in flight on this repo.

Four new rows per locale: the save-time error, the browser-side rule
message, and the two admin-copy sentences. Terminology follows the
rows already in each file - Limit = Grense / Limiet / Grans, Fixed
Amount = Fast belop / Vast bedrag / Fast belopp - rather than being
translated afresh.

Refs TWO-25289.

Subject: [PATCH 184/885] TWO-25289/fix(surcharge): round relayed monetary
 values to 2dp, and de-contradict the guidance

Two things, both fallout of refusing a zero limit at the admin
boundary.

1. `convertAmount()` sent its result unrounded. The API refuses
   monetary values finer than two decimal places rather than rounding
   them, so an FX conversion landing on >2dp (349 * 0.0872 = 30.4328)
   was rejected upstream and surfaced to the buyer as the generic
   "temporarily unavailable" error. Both `cap` and `surcharge` are now
   rounded, on the no-conversion path too - an admin can type more
   precision than the API accepts.

   Plain half-up rounding, deliberately. Sub-cent caps, away-from-zero
   rounding and zero-decimal currencies are all out of scope: the one
   value where the rounding direction would have mattered, an explicit
   cap of 0, is refused by the grid instead. A sub-cent cap rounding to
   0.00 is pinned by its own test so it reads as a decision rather than
   a surprise.

2. The prose merged with the TWO-25269 revert told the next reader not
   to add admin validation rejecting a typed zero - correct as a
   statement about the RUNTIME relay, wrong as guidance, and sitting in
   the first file an implementer of this change would open. Rewritten
   in both places (the inline comment and AGENTS.md) to hold both rules
   and say why they do not conflict: the runtime relays a zero cap
   faithfully because the API bounds the fee at zero rather than
   uncapping it, AND the admin refuses zero because a merchant wanting
   no fee says so with 0% and 0 fixed, while the sibling plugins were
   turning a zero cap into "absent" and relaying it genuinely uncapped.

The test that pinned the unrounded pass-through was pinning the bug -
and asserted nothing, so it was also risky-flagged. Replaced with two
that pin the rounding. Verified by mutation: dropping either round()
reddens exactly the test for that path.

Refs TWO-25289.

+reverted** — a zero cap bounds the fee at zero, it never uncaps it.
 In `fixed_and_percentage` mode the cap bounds the combined fee, so
 `Limit = 0` suppresses the fixed component too, not just the
 percentage part.
-
 `Test/Unit/Service/Order/SurchargeCalculatorTest.php` pins this.
 
+**Admin — refuse zero.** Separately, TWO-25289 stopped a zero limit
+being *configurable*: `Model\Config\Backend\SurchargeGrid` rejects
+`limit === 0` on save, and the grid refuses it in the browser too.
+An EMPTY limit stays valid and still means "no limit".
+
+This is not the reverted guard under another name. It is an
+admin-boundary decision rather than a runtime one, and the reason is
+different: a merchant who wants no fee on a term says so directly
+with 0% and 0 fixed, so a zero limit has no legitimate use — while on
+the sibling plugins a zero cap was being normalised to *absent* and
+relayed genuinely uncapped, overcharging the buyer. Refusing it at
+entry closes that consistently across all three plugins.
+
+So: if you are asked to remove the admin validation, that is the
+runtime rule being misread. If you are asked to make the runtime
+throw on a zero cap, that is the reverted guard being reintroduced.
+Neither follows from the other.
+

Adversarial review found one blocker and five real defects. Fixes:

BLOCKER - a limit of 0 stored while it was still legal made the whole
Two payment section UNSAVEABLE. The grid JS hides the Limit column for
a fixed-only surcharge type, but a hidden input still posts, and
client-side validation skips hidden fields, so the stored 0 arrived
server-side and threw - naming a cell the admin can neither see nor
clear. Now an inapplicable limit is DELETED rather than validated,
which also retires the legacy row instead of leaving it to resurface.
Same reasoning the funding-partner cap check already carries: failing
a save over an invisible cell is a dead end.

The type gate reads the POSTED surcharge type, not the stored one: type
and grid are saved in the same request, so the stored value is the
previous one and would misjudge the merchant switching type - which is
exactly the case that decides whether their save is blocked.

A SUB-CENT limit (0.001) passed validation and then became a hard cap
of 0.00 once rounded for the wire - the very outcome being refused,
one step later. The check is now round($value, 2) === 0.0, so the
rounding direction cannot decide whether a configured cap survives.
Both prose claims to that effect were false as written; corrected
rather than deleted, because the FX-conversion case genuinely remains
and is pinned as accepted.

NON-NUMERIC input had no server-side check at all. Cast to float,
'abc' is 0.0, so it was rejected as "a limit of 0 is not allowed" -
wrong and unactionable. validateValue() now takes the RAW string so it
can tell the two apart, with its own message.

A stale docblock paragraph directly contradicted the new one ("the
result is returned unrounded"); deleted. The MONEY_DECIMALS comment
claimed every monetary value is rounded, when gross_amount and
rounding.step are not; scoped to what it does.

The registered JS rule had three defects: $t() around a
`+`-concatenated literal, which Magento's phrase collector cannot
harvest, so the three new i18n rows were dead and the message would
have stayed English; the message resolved at define time, before the
dictionary is guaranteed registered; and an `if ($.validator && ...)`
guard that would silently skip registration while the rendered
data-validate attribute still named the rule, making jquery.validate
throw on submit and kill validation of the whole form. One unbroken
literal, lazy function, no guard.

Two of round 1's new tests were exercising the test stub rather than
production code - the exact can't-fail pattern this PR's own commit
message called out. Both moved onto the real methods via reflection.
Mutations verified: dropping is_numeric, inverting the type gate, and
reading the stored type instead of the posted one each redden exactly
one test.

Refs TWO-25289.

+
+That is safe for anything a merchant can **configure**, because the
+grid refuses any limit that rounds away at 2dp — not just an explicit
+`0` but anything under half a cent. So the rounding direction never
+decides whether a configured cap survives.
+
+What it does **not** cover is an FX conversion landing under half a
+cent: that collapses to `0.00` and suppresses the fee. Accepted, not
+overlooked — pinned by
+`testASubCentCapRoundsDownToZeroWhichIsAcceptedScope` so it reads as a
+decision. Do not "fix" it with away-from-zero rounding without
+reopening the scope question.
+
+Also note the Limit column is **deleted rather than validated** when
+the surcharge type has no percentage component. The grid JS hides that
+column, but a hidden input still posts, so a limit stored under an
+earlier percentage type keeps arriving. Rejecting a zero there would
+fail the whole section save over a cell the admin cannot see or clear.

Subject: [PATCH 186/885] TWO-25289/fix(ci): teach the JS harness what
 mage/validation provides, and test the rule

Jest went red on the surcharge-grid smoke load: dropping the
`if ($.validator && ...)` guard exposed that the AMD harness's jQuery
mock carries neither `$.validator` nor `$.mage.parseNumber`, both of
which `mage/validation` provides in the browser. A jQuery without them
is a shape no browser presents, so the failure was testing the mock,
not the module - the guard had been hiding a harness gap as well as a
real defect. Mock fixed rather than guard restored.

The mock's parseNumber reproduces the comma-decimal behaviour
deliberately: parseFloat('0,5') is 0, and that difference is the entire
reason this rule exists instead of Magento's locale-blind
validate-greater-than-zero. A mock that used parseFloat would let the
locale bug through unnoticed.

With the registry mocked, the rule itself is now directly testable, so
it is tested rather than merely smoke-loaded: zero in every spelling,
sub-cent values, empty, comma decimals, non-numeric left to the
sibling rule, and the message being a lazily-resolved function.
Mutations verified - reverting the sub-cent rounding, and swapping
parseNumber for parseFloat, each redden one case.

Refs TWO-25289.

Round 1's fix for the unsaveable-grid dead end had three problems of its
own, all found by round 2.

DELETING an inapplicable limit was wrong twice over. It discarded a
VALID limit on any save made while the surcharge was fixed-only or off -
a normal round trip, and one that kept the equally inapplicable
percentage cell. And at a non-default scope, deleting an override does
not retire a value at all: it re-exposes the parent's, so a legacy zero
at default scope produced an unsaveable loop at store scope - reject the
posted inherited zero, clear it, the override is deleted, the next
render shows the inherited zero again, and the error's "leave the limit
empty" was actively wrong there. The column-visibility gate now
suppresses only the ZERO RULE; the cell is stored either way, and a
legacy zero resurfaces when the column comes back into view, which is
where the admin can act on it.

The TYPE READ was unscoped. The config fallback is not an edge case: a
type field left on "Use Default Value" renders its select disabled, and
browsers do not submit disabled inputs, so nothing is posted for it -
which makes the fallback the normal path at a non-default scope, where
an unscoped read returns the DEFAULT scope's value. Default fixed +
website percentage would have silently deleted a store's real limits;
the reverse would have blocked its whole section save. Resolved at the
saving scope now, as the sibling render block already does.

is_numeric('1e400') is true and the cast is INF. Limit is the one column
with no upper bound, so INF was stored and then failed the pricing
request at serialisation time, a long way from the cause.

Test debt from round 1, which the review was right to call a recurrence:
the delete-path test exercised only the stub, so removing the production
wiring kept the suite green. The rule and the type gate are both pinned
against production code now, including the scoped fallback (via a
reflection-injected scope config), and the stub keeps only the flow it
is honest about. MONEY_DECIMALS is duplicated across the grid and the
calculator and the whole correctness argument depends on the two
agreeing, so a test now pins that.

Also: the Jest parseNumber mock only handled a single comma, so
'1.234,56' parsed as 1.234 - the mock diverging from the real parser in
exactly the locale behaviour it exists to cover, which is false
confidence rather than coverage. It implements last-separator-wins now,
with a test.

Copy: the zero-limit sentence loses its possessive apostrophe, matching
the sibling plugins. PrestaShop keys its translations on the md5 of the
BACKSLASH-ESCAPED source, so an apostrophe there silently yields a dead
key; sidestepping it in the shared wording beats getting the escaping
right in one plugin and wrong in the next.

Mutations verified: dropping the visibility gate, unscoping the fallback
read, dropping is_finite, and breaking MONEY_DECIMALS parity each redden
exactly the intended test.

Refs TWO-25289.

Three round-3 findings.

1. The stored surcharge limit was cast blindly on read, so a value that
   never came through the admin grid decided the buyer's fee. A
   hand-edited row, a config:set or an import could store `abc`, which
   cast to a hard cap of 0.0 and suppressed the fee outright, or `-10`,
   which was relayed as a negative cap and refused upstream so the buyer
   saw a generic failure. Non-scalar, empty, whitespace-only,
   non-numeric, non-finite and negative now all resolve to NULL, i.e.
   absent, i.e. no cap. A genuine 0 is still relayed verbatim: a zero cap
   clamps the fee to zero, which is a different instruction from
   absence. Same shape as the sibling plugins.

2. Round 2's limit-column visibility wiring was untested. validateValue()
   defaults the flag to true, so deleting the argument at the call site —
   or dropping the term from the rule — compiled and left the suite green
   while reintroducing the failed-section-save regression round 2
   removed. Both directions are now pinned against the REAL afterSave(),
   which needed afterSave() and an explicit setData() on the test stubs
   before the production method was callable at all.

3. AGENTS.md still described the hidden Limit column as deleted rather
   than validated. Round 2 changed that to skipped-not-deleted, so the
   doc was instructing a future reader to reintroduce the regression.
   Corrected, with the reason deleting is wrong, and a new section for
   the read-path guard.

 So: if you are asked to remove the admin validation, that is the
 runtime rule being misread. If you are asked to make the runtime
 throw on a zero cap, that is the reverted guard being reintroduced.

Subject: [PATCH 189/885] TWO-25289/test(surcharge): pin the non-scalar limit
 guard on the diagnostic, not the result

The array case asserted only that the limit read as absent, which held
with or without the guard: the string cast yields "Array", which is
non-numeric and lands on null anyway. The cast is a PHP warning rather
than an error, so the assertion that actually distinguishes the two is
that no diagnostic is raised.

Subject: [PATCH 190/885] fix(company-search): gate the deferred manual-entry
 teardown on bind staleness

Round 2 adversarial review (Han, Vader, both independently) found that
the setTimeout(0) deferral added in the previous fix had no staleness
check: every other deferred/async call in this handler chain
(onSearching, onUnavailable, clearSearchChrome, attachManualEntryRow)
gates on the bind staying current, but the manual-entry teardown acted
unconditionally through `self`. A checkout re-render landing in the
zero-delay gap between the buyer's click and the timer firing would
tear down whatever widget is live NOW rather than no-op for the stale
bind, and the eagerly-resolved `$searchForCompany` reference from the
same gap could operate on a detached node.

Gates the deferred callback on companySearch.getSearchFieldContainer()
staying non-empty for the bind token, and moves `$searchForCompany`
resolution inside the deferred body instead of before it (Yoda,
round 2). New regression test proves reverting the staleness check
goes RED.

Subject: [PATCH 191/885] fix(ci): drive the payment tile's manual-entry row
 the way it now works

TWO-25288. Four cases in company-search-return-to-search.test.js fail on
staging, on nobody's branch. The payment surface's manual-entry exit stopped
being a "#billing_enter_details_manually" link below the results and became a
cancellable row inside them, but that landed AFTER this file did, so the
helper's click found no node and every case that routes through manual entry
died in the fixture.

Drive the real route instead: trigger the preventable select2:selecting
pre-event with a sentinel row, then run the deferred teardown. Two things the
straightforward version of that gets wrong:

  - jest.useFakeTimers() cannot reach the deferral. The AMD harness copies the
    real setTimeout into its vm sandbox when the module loads, so a later timer
    swap patches a binding the module never sees. The fixture supplies a
    queueing setTimeout through extraGlobals and flushes it explicitly, which
    also keeps the defer visible rather than collapsing it to a synchronous
    call.
  - the teardown is gated on the bind still being current, which the default
    company-search mock answers with null. getSearchFieldContainer now reports
    a live bind, alongside the sentinel-aware isManualEntryOption the shipping
    surface already needed.

The flush reports how many callbacks it ran and the helper refuses a run that
deferred none, so a future regression that stops reaching the handler fails
loudly instead of asserting against a widget nothing asked to tear down.

Verified against origin/staging with only this file changed: 249/249, from
4 failing.

Subject: [PATCH 192/885] feat(TWO-25288): show the captured company name and
 number, read-only
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Supersedes the removal of the payment tile's company-number input. The reason
it was removed holds — a hand-typed organisation number is not an accepted
source; it produced poor data quality and genuine buyers receiving invoices for
orders they never placed — but removing the field also stopped the buyer seeing
what the order would be invoiced against. Read-only keeps the first and
restores the second, on every capture mode.

The number field is back as a labelled input, `readonly` as a STATIC attribute
(there is no mode in which it may be typed), bound to `value: companyId`, and
deliberately carrying no `name` and no `required`:

  - no `name`, so it adds no second carrier for a value getData() reads off the
    observable. The observable stays the only thing that ships.
  - not `required`, because a read-only empty required field fails validation
    with no way for the buyer to satisfy it. Model/Two.php::authorize() remains
    the only enforcement of the number's presence, unchanged by this commit.
  - `readonly`, not `disabled`: a disabled control is dropped from the
    submitted form and skipped by jQuery Validation's `elements()`.

The name field's `readonly` is BOUND, to sole-trader mode only, and the
asymmetry is load-bearing. Sole trader is the one mode where that node is a
plain text box holding a captured name the buyer must not edit. In search mode
select2 replaces it with its own chrome; in manual-entry mode the buyer MUST be
able to type, and a static `readonly` would brick that mode outright.

clearCompany() now blanks `companyId()`. While the tile had no number field the
stale observable was invisible and was flagged as out of scope; with the number
displayed, leaving it set would show the buyer the ABANDONED company's registry
number, uneditable, beside a name they are being asked to retype — and submit
that number under the new name. `companyName()` is deliberately NOT cleared: it
is read after the call on the sole-trader path (getAutofillData() prefills the
signup popup from it) and by the intent-approved notice.

The grey inline hint that briefly stood in for the field is gone, markup and
CSS together — a labelled field supersedes it, and both would have shown the
buyer the same number twice. Its address-step half, the CSS-only hide, is
untouched and keeps its own pins.

Tests read the `value:` and `readonly:` binding targets out of the template and
evaluate them against a renderer driven through each real capture flow, so a
field bound to the wrong observable fails even with correct-looking markup.
Every read-only assertion in the first draft passed against a template with the
attribute DELETED, because `\breadonly\b` matches inside the class name
`two-company-id-readonly`; attribute matching is now anchored on whitespace.
Caught by mutation, and each of five mutations is confirmed to fail the suite:
dropping the static attribute (5), removing the field (6), making the name
statically read-only (2), unclearing companyId in clearCompany (1), and
rebinding the number to companyName (5).

npm run test:js: 21 suites, 253 tests, all passing.

- *  2. ACCEPTED-SOURCE REGRESSION PINS — most of 'an accepted organisation

- *     number outright rather than fall back to a field — and the sole-trader
- *     routes are the ones most likely to break silently, their value being
- *     minted rather than picked.
+ *  2. WHAT-THE-BUYER-SEES PINS — 'what each capture mode puts in front of the

+ *     target out of the template, then evaluate it against a renderer driven
+ *     through the real capture flow, so a field bound to the wrong observable

Two real findings from an independent adversarial round on the diff.

MAJOR — the name field could be blank, `readonly` and `required` at once, which
is a validation error no buyer action clears. jQuery Validation enforces
`required` on a `[readonly]` field; its `elements()` skips `:disabled` only.
Keying `readonly` on sole-trader mode alone hit that: enterSoleTraderUi() blanks
the input, and the autofill only refills it when the prefetch matched a buyer —
fillCompanyData() early-returns unless BOTH name and number are non-empty. On
the unmatched branch the buyer is sent to signup and may abandon it, and any
autofill buyer with an empty organisation number lands there too. Before this
change the buyer could retype; the first draft took that away.

Now bound to isCompanyNameReadOnly(), which is `showSoleTrader() &&
!!companyId()` — lock only once a number has actually been captured, so every
state in which the field is empty is a state the buyer can type into. A plain
method rather than a computed: the template calls it inside the ko `attr`
binding, so ko tracks both observables as dependencies of that binding, there is
no subscription to dispose, and it exists on renderers the unit tests load
without booting.

MAJOR — the comments this change edited (and inherited) asserted that the
address step is "the sole hand-typed route" for the organisation number. It is
not a route at all: that field carries `two-company-id-hidden` from
Plugin/Model/Checkout/LayoutProcessorPlugin.php and `display: none` from the
stylesheet, unconditionally, with nothing anywhere removing the class. So no
buyer can hand-type an organisation number ANYWHERE in the plugin, and an
identifier-less company is a dead end refused by Model/Two.php::authorize().
Corrected in all three places rather than left as an escape hatch a future
reader would go looking for. Whether that field should be unhidden when
needsManualCompanyId() is a separate decision, not taken here.

MINOR — the manual-entry helper's flush guard accepted any queued callback, and
the injected setTimeout catches every timer the module sets (showErrorMessage's
dismissal is the other). Tightened to exactly one.

Two new cases pin the MAJOR directly: sole-trader mode entered with nothing
captured, and a captured company abandoned by the mode switch. Both assert the
field is NOT locked.

Mutation-verified, six mutants, all killed: name readonly keyed on mode alone
(2 — the bug above), always true (4), always false (2), static readonly dropped
from the number (5), clearCompany not clearing companyId (2), a `name` attribute
added to the number (1).

npm run test:js: 21 suites, 255 tests, all passing.

Subject: [PATCH 194/885] fix(a11y): make "Search for company"
 keyboard-reachable on Luma
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Both the shipping-step and payment-step "Search for company" controls
rendered as a plain <div class="search_for_company"> with only a click
handler — no tabindex, role, or keydown binding, so keyboard users
could not reach or activate them at all.

Add role="button", tabindex="0", and Enter/Space keydown handling to
both address-autocomplete.js and gateway_method.js, matching the
pattern already correct on Hyvä (companyName.phtml) and shipped on
WooCommerce.

Subject: [PATCH 195/885] fix(i18n): translate the Company number/name labels
 on the Hyva payment tile

gateway_method-csp-js.phtml renders "Company number:" and "Company
name:" via __() but these two exact strings (with the trailing
colon) had no rows in nb_NO/nl_NL/sv_SE, so they silently fell back
to English. Add both, reusing the wording already shipped for
"Company Number"/"Company Name" elsewhere in the same dictionaries
plus a trailing colon (matching the existing "Merchant ID:" pattern).

Subject: [PATCH 196/885] fix: guard against double-activation from a synthetic
 click after Enter

Adversarial review (Vader) flagged that some assistive-tech/browser
combinations forward a synthetic click in addition to the Enter
keydown for a role="button" div (as opposed to a native <button>).
Without a guard, a second call to activateSearchForCompany() would
re-open a dropdown the buyer already opened. Early-return once the
control is hidden.

Three live bugs Doug found testing Luma checkout this morning (#30.x.11):

- Company search never got the CSS side of last night's WC/PS keyboard-
  reachability work: text-transform scoping, select2 vertical alignment, and
  a visible focus indicator on the "Search for company" control. PR #311
  already fixed the JS keyboard behaviour (role/tabindex/Enter-Space); the
  matching CSS never landed alongside it.

- The payment tile showed the captured company number as a second, separate
  read-only input. Canonical design across all four platforms (Doug's
  ruling): a plain text label immediately below the company-name field,
  right-aligned to it, visible only once a number has actually been
  captured.

- Country rendered after street/company. checkout_index_index.xml already
  declares country_id's sortOrder as a static 50, which does win over
  Magento core's EAV default — but company/street carry no override of
  their own, so their position depends entirely on the store's Customer
  Address Attributes admin configuration, and this staging store's config
  pushes them below 50. LayoutProcessorPlugin now reads company's actual
  resolved sortOrder back out of the array (after core's own merge) and
  forces country immediately before it, mirroring PrestaShop's
  CustomerAddressFormatter::moveFieldBefore('id_country', 'company') —
  dynamic relative positioning instead of a static number.

+                            than as an empty box. Nothing client-side
+                            enforces the number's presence either way;

Subject: [PATCH 198/885] =?UTF-8?q?fix(checkout):=20address=20review=20rou?=
 =?UTF-8?q?nd=201=20=E2=80=94=20unconditional=20reorder,=20dropped=20a11y?=

MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Three real defects from an independent adversarial round (Han/Vader/Yoda),
all confirmed before fixing rather than taken on faith:

- moveCountryBeforeCompany() anchored to company's sortOrder alone and
  rewrote country_id unconditionally on every render — the live bug was
  reported as "country after STREET", which the fix never checked, and an
  unconditional rewrite could push country past some other field even on a
  store that never had the bug. Now anchors to min(company, street) and only
  acts when country is not already ordered correctly; added an is_array
  guard on a malformed non-array country_id.

- The payment-tile label removed the entire "Company Number" caption along
  with the old input, leaving a bare number with no indication of what it
  was — a real regression for sighted buyers and assistive tech. Restored as
  a static caption span alongside the number span (no `for`/id association,
  since there's no control left to associate with).

- The address-step company-search dropdown CSS was scoped by
  `#select2-company-container`/`#select2-company-results`, assuming select2
  derives those ids from the field's own `id="company"`. Verified live: the
  actual id is a Magento-generated uid (`id="S0FR5JB"`), not "company" —
  those selectors were dead CSS. Re-scoped the selection box via the
  adjacent-sibling selector already used elsewhere (id-independent), and
  dropdown rows via `dropdownCssClass: 'two-company-search-dropdown'` set
  on both select2 inits — select2's own supported hook for this, immune to
  its id-generation fallback.

Subject: [PATCH 199/885] =?UTF-8?q?fix(checkout):=20address=20review=20rou?=
 =?UTF-8?q?nd=202=20=E2=80=94=20shared=20dropdown=20class,=20locale-safe?=
 =?UTF-8?q?=20caption,=20symmetric=20test?=
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Three NITs from a clean round-2 adversarial pass:

- dropdownCssClass was hardcoded as an independent literal at both select2
  init call sites. Hoisted to a single companySearch.DROPDOWN_CSS_CLASS
  constant, same convention MIN_INPUT_LENGTH already establishes in the same
  module, so a rename at one site can't silently orphan the CSS at the other.

- The restored "Company Number" caption glued a literal ASCII colon outside
  the translated string — wrong punctuation/spacing for some locales. Now
  reuses the bare, already-translated 'Company Number' string (no new
  untranslated msgid) and separates caption from number via a CSS line break
  instead of hardcoded punctuation. Strengthened the Jest pin to require the
  caption is delivered via the ko i18n macro specifically, not merely present
  as a string — a second adversarial round found the original test would
  pass equally against a hardcoded, no-longer-translatable caption.

- Added the symmetric PHPUnit case the anchor loop's own shape implied
  (`company` missing entirely, anchor falls back to `street` alone) —
  present for the reverse (street missing, anchors on company) but missing
  here.

Subject: [PATCH 200/885] fix(checkout): manual-entry affordance is a real
 button outside the results list (#30.x.15)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Three live bugs Doug found testing Luma checkout after PR #313 merged:

- The company-search "My company is not on the list" affordance was a
  `<li role="option">` living INSIDE the select2 results list. That kept it
  reachable by select2's own arrow-key model, but traded that for two other
  defects found live: it was only visible once the buyer scrolled past
  however many real results came back (`.select2-results__options` is
  exactly what select2 clips and scrolls), and Space did nothing on it —
  select2's core only special-cases Enter/Up/Down/Escape, so an unhandled
  Space fell through to typing a literal space into the search box.

- Converted it to a real `<button type="button">`, a SIBLING of the results
  list rather than a row inside it (matching the WooCommerce plugin's own
  fix for the same defect): native Tab-adjacent focus, native Enter AND
  Space activation with no bespoke keydown bridge, and a position outside
  select2's scroll/clip area so it is always visible once the search
  threshold is met — no MutationObserver needed either, since a sibling
  survives select2 repainting the list on every new page of results.

- Re-verified the payment-tile "Company Number" field's gating
  (`visible: !!companyId()`, PR #313): the template and CSS are already
  correct on staging. Live testing showed the OLD always-visible editable
  input, which points at a deploy-lag gap between merge and the staging
  pod picking it up, not a code defect — flagged for infra follow-up rather
  than "fixed" here.

company-search.js: buildManualEntryOption/renderManualEntryRow/
attachManualEntryRow/detachManualEntryObserver/isManualEntryOption replaced
with buildManualEntryButton/syncManualEntryButton/attachManualEntryButton/
detachManualEntryButton. Both call sites (gateway_method.js,
address-autocomplete.js) no longer intercept `select2:selecting` for a
manual-entry sentinel — the button's own click handler defers straight to
each surface's existing teardown (clearCompany() / enterDetailsManually()).

  * Copyright © Two.inc All rights reserved.

  *
- * Follow-up from PR #305 (address-step manual-entry affordance, open and
- * unmerged as of this writing): the payment-tile company picker
- * (`gateway_method.js`) rendered its own manual-entry affordance OUTSIDE the
- * select2 results listbox — the same accessibility defect #305 fixes on the
- * address step, tackled here independently for the payment tile so the two
- * pickers don't ship on opposite sides of the fix. This file pins the
- * shared-model fix and the payment-tile surface's use of it.
+ * #30.x.15 payment-tile follow-up. The shared model's DOM-level contract for
+ * the manual-entry button (a real `<button>`, a sibling of the results list,
+ * threshold-driven, staleness-checked) is pinned in
+ * company-search-manual-entry.test.js — this file covers only what is
+ * specific to the payment-tile surface (`gateway_method.js`): it must wire
+ * the SAME shared helpers, with an activation callback that tears down this
+ * picker's own widget (`self.clearCompany()`) and brings back the "Search
+ * for company" link, rather than address-autocomplete.js's
+ * `enterDetailsManually()`.
  *
- * Load-bearing guarantees:
- *  - the manual-entry row is a REAL row INSIDE the results list (`<li>`,
- *    `role="option"`, `--selectable`, matching `aria-activedescendant`
- *    plumbing via `_resultId`), not a footer div outside it. Outside the
- *    list it sits outside the combobox's `aria-owns`, so no key reaches it
- *    and no screen reader announces it;
- *  - it appears at the shared MIN_INPUT_LENGTH threshold and survives a
- *    result-list re-render (select2 empties the list on every new page of
- *    results);
- *  - a stale bind token can never paint a row onto a widget it doesn't own;
- *  - the payment-tile surface (`gateway_method.js`) wires the model's
- *    `attachManualEntryRow` / `detachManualEntryObserver` and intercepts
- *    `select2:selecting` for the sentinel row, and no longer builds the old
- *    outside-the-listbox div.
- *
- * Mutation-resistance notes:
- *  - the model tests run against REAL jsdom nodes through a small
- *    jQuery-lite double, so `length`, class lists, attributes and sibling
- *    order are the document's answers, not a stub's;
- *  - the threshold is exercised at MIN_INPUT_LENGTH - 1 and MIN_INPUT_LENGTH
- *    read off the module's own exported constant, so a literal "3" drifting
- *    from the real constant would still be caught structurally (the row's
- *    presence/absence is asserted against the module's threshold, not a
- *    hardcoded number);
- *  - translation is asserted on the msgid, since `$t` resolves to identity
- *    here;
- *  - the surface test greps the real gateway_method.js source, so deleting
- *    the wiring (reverting to the old div) fails it directly.
+ * Structural (source-grep) tests only: the surface's business logic here is
+ * a couple of lines of glue around calls the shared-model suite already
+ * proves correct in isolation, and jest-mocking gateway_method.js's full KO
+ * component just to re-prove `attachManualEntryButton` was called would add
+ * a second, weaker copy of that coverage rather than new coverage.

- * TWO-25288 element 5. The manual-entry affordance on the address step.
+ * #30.x.15. The manual-entry affordance was previously a real `<li
+ * role="option">` living INSIDE the select2 results list, on the premise
+ * that inheriting select2's own keyboard model was the only way to keep it
+ * reachable. Live testing after that shipped found the tradeoff was worse
+ * than the defect it fixed:
  *
- * What changed, and therefore what these tests have to hold down:
- *  - it is now the LAST ROW INSIDE the results list, not a div appended
- *    outside it. That is the whole accessibility fix: outside the list it sat
- *    outside the listbox the combobox owns, so no key reached it and no
- *    screen reader announced it;
- *  - it appears as soon as the term reaches the shared threshold, on `input`,
- *    ahead of the debounced request — the buyer whose company is not in the
- *    registry must not have to wait out a search that cannot help them;
- *  - it survives every re-render, because select2 empties the list on each
- *    new result set;
- *  - activating it is intercepted and cancelled, so the sentinel row never
- *    reaches the code that treats a selection as a company.
+ *  - `.select2-results__options` is exactly the element select2 clips and
+ *    scrolls, so the row was only visible once the buyer scrolled past
+ *    however many real results came back, and reaching it by keyboard meant
+ *    arrowing down through every one of them;
+ *  - Enter worked (it closes over select2's own `select2:selecting`
+ *    dispatch), but Space did not: select2's core only special-cases
+ *    Enter/Up/Down/Escape on the search field's keydown, so an unhandled
+ *    Space fell through to its native default of typing a literal space
+ *    character into the search box.
  *
- * Mutation-resistance notes, because this repo's harness makes vacuous
- * assertions easy:
- *  - the model DOM tests run against REAL jsdom nodes through a small
+ * This file pins the replacement: a real `<button>`, a SIBLING of the
+ * results list rather than a row inside it, which fixes both by
+ * construction — native Tab-adjacent focus, native Enter/Space activation,
+ * and a position outside select2's own scroll/clip area so it is always
+ * visible once the search threshold is met.
+ *
+ * Mutation-resistance notes:
+ *  - the model tests run against REAL jsdom nodes through a small
  *    jQuery-lite double, so `length`, class lists, attributes and sibling

-         * by no key. Inside the list it inherits select2's own keyboard model
-         * for free.
-         *
-         * Every attribute here is load-bearing:
-         *  - the `--selectable` class is what the bundled select2 walks when
-         *    the buyer presses the arrow keys, and what it highlights;
-         *  - the absence of a `--selected` class keeps activation routed to
-         *    selection. Marking the row selected instead routes Enter to
-         *    "close the dropdown", and the row does nothing at all;
-         *  - the payload needs an `id`, because select2 stringifies `data.id`
-         *    for every selectable row when it reconciles the rendered list
-         *    against the current selection. Without one the row is compared
-         *    under the literal string "undefined", so it matches any other
-         *    id-less row and can be marked selected on that basis. It does not
-         *    throw — the call that would is on a path this row bypasses;
-         *  - the payload's `_resultId` must equal the row's DOM id: that is
-         *    the value select2 copies into the listbox's
-         *    `aria-activedescendant`, so a screen reader announces the wrong
-         *    row (or none) if the two disagree.
-         *
-         * The label is written with `.text()`, never interpolated into markup:
-         * this picker sets select2's `escapeMarkup` to the identity function
-         * so that server-side result highlighting can render, which means a
-         * translation catalogue would otherwise be an HTML injection point.
-         *
-         * @param {string} [resultsId] DOM id of the results `<ul>`, used to
-         *        derive a row id unique to this picker
-         * @returns {object} jQuery-wrapped `<li>`
+         * Build the manual-entry affordance as a real, focusable `<button>`
+         * (#30.x.15).
+         *
+         * The `<li role="option">` version this replaces put the row INSIDE
+         * `.select2-results__options` on purpose, so it inherited select2's
+         * own keyboard model and its `aria-owns` reachability. In practice
+         * that traded one accessibility gap for two others, discovered live
+         * after that version shipped:
+         *
+         *  - `.select2-results__options` is exactly the element select2
+         *    applies its own scroll-and-clip to, so the row was only ever
+         *    visible once the buyer scrolled past however many results came
+         *    back, and arrowing down through every one of them was the ONLY
+         *    way to reach it by keyboard;
+         *  - Enter closed over select2's own `select2:selecting` dispatch and
+         *    worked, but Space does not: select2's core only special-cases
+         *    Enter/Up/Down/Escape on the search field's keydown, so an
+         *    unhandled Space fell through to its native default — typing a
+         *    literal space character into the search box — rather than
+         *    activating the highlighted row.
+         *
+         * A real `<button>` fixes both at once: native Tab-adjacent focus
+         * order, native Enter AND Space activation (nothing here has to
+         * special-case either key), and a `click` handler that only ever
+         * fires for the primary mouse button. No bespoke keydown bridge.

Adversarial review (Han/Vader/Yoda) on the round-1 button conversion found
one real BLOCKER and several BUGs:

- BLOCKER (Yoda): select2 4.1's own search-field keypress handler treats
  Tab exactly like Enter (`t===ENTER||t===TAB`, both trigger
  `results:select` + `preventDefault()`), bound at widget construction —
  before this module touches the field. Tab could therefore never reach
  the button at all, keyboard-only. Fixed with a capture-phase native
  `keydown` listener on the search field (installed in
  attachManualEntryButton, removed in detachManualEntryButton) that wins
  the race and moves focus onto the button on Tab-without-shift.

- BUG (Yoda): Escape did nothing once focus reached the button (select2
  never sees the keypress once focus has left the search field). Handled
  on the button's own keydown: closes the picker, returns focus to the
  combobox.

- BUG (Yoda): the button dropped out of this repo's own
  `text-transform: none !important` uppercase defense — already fixed
  twice on other elements, now on this real `<button>` too, since it's
  now squarely in the blast radius of broad Luma uppercase rules that a
  `<li>` pseudo-option wasn't.

- BUG (Yoda): the button wasn't in the search field's `aria-owns`/
  `aria-controls` IDREF lists, so it had no accessible relationship to
  the combobox even though native focus/keyboard now reaches it. Fixed:
  its id is appended to both lists when shown, stripped when hidden or
  torn down.

- BUG (Vader): activating the button (click/Enter/Space) tore down the
  select2 widget, which removes the button — the focused element — from
  the document without routing through select2's own `close` (which is
  what normally refocuses the combobox). Focus fell back to `<body>` with
  nothing visibly focused. Both call sites now explicitly refocus after
  teardown (the plain-text field on the address step, the "Search for
  company" link on the payment tile).

- BUG (Vader): inserting/removing the button never told select2 to
  recalculate the dropdown's geometry — that only happens on select2's
  own result/selection events or a window resize, and the button is
  inserted synchronously ahead of the ajax debounce specifically so it's
  visible before results land. Fixed: pokes select2's own
  `resize.select2.<id>` handler after every insert/remove.

Also folded in the cheaper findings from the same round:
- Vader NIT: detachManualEntryButton's button lookup now goes straight by
  class, scoped to the dropdown, instead of via the results `<ul>`'s
  parent — the indirection could fail open and leave a button (and its
  handlers, and a pending activation timer) wired to a disposed renderer.
- Han/Vader: the deferred activation timer is now tracked and cancelled
  on detach, so closing the dropdown in the gap between activation and
  the deferred tick can no longer fire onActivate() against a picker the
  buyer has already left.
- Stale "manual-entry row" wording swept from a comment that predates
  this PR's own button conversion.

New tests pin the Tab-capture fix directly (forward Tab intercepted and
refocused, Shift+Tab left alone, listener removed on detach) and Escape
handling. `Test/Js/company-search-manual-entry.test.js`'s own mini-jQuery
double gained `trigger`/`removeAttr`/`removeData` to model what real
jQuery already provides — mutation-checked: reverting the Tab handler's
preventDefault+focus fails the new test.

`npx jest --config Test/Js/jest.config.js` — 21 suites, 249 tests, all
green (4 new).

Round-2 adversarial pass (Vader + Yoda, against just the round-2 fix
commit) found the round-2 Tab fix was itself incomplete, plus proved
several round-2 tests vacuous by mutation:

- BLOCKER (Vader): select2 4.1's Tab-hijack has NO `shiftKey` guard
  (`t===ENTER||t===TAB` fires identically either way), so Shift+Tab
  from the search field still reached select2 and silently selected
  the auto-highlighted first result — committing a company the buyer
  never chose. Worse than the forward-Tab defect this whole fix exists
  for, since it commits a choice instead of just failing to navigate.
  Fixed: the capture-phase listener now intercepts Shift+Tab too.

- BUG (Vader): the button was a one-way focus door. AttachBody appends
  the dropdown as the last child of `<body>`, so forward Tab from the
  button walked out of the document entirely and Shift+Tab landed on
  the page's last focusable element — neither useful. Fixed: the
  button's own keydown now treats Tab (either direction) the same as
  Escape — close the picker and let select2's own close() refocus the
  combobox, rather than guessing at a "natural" focus target that
  doesn't structurally exist here.

- BUG (Yoda): `aria-owns` on the search field was semantically inert —
  `role="searchbox"` is a leaf widget and AT doesn't expose owned
  children of one — and asserted a parent/child relationship that
  isn't structurally true. Dropped; `aria-controls` (which select2
  itself already uses on this element) is the one carrying real
  meaning, kept as-is.

- BUG (Vader): the dropdown-geometry resize nudge only fired on
  insert, not on the below-threshold removal path — which shrinks the
  panel by exactly the same synchronous, pre-results margin insertion
  grows it by. Both paths now go through one `nudgeSelect2Resize()`
  helper.

- NIT (Vader): the Escape handler's manual refocus was dead weight
  (select2's own `close()` already refocuses the combobox) and its
  fallback branch targeted a non-focusable node. Replaced with a single
  shared `closeDropdown()` helper used by both the button's keydown and
  the search field's Shift+Tab interception — one code path, and
  select2 owns the refocus.

Test vacuity, proved by Vader deleting each piece independently and
watching 21/21 suites, 249/249 tests stay green:
- the "Tab moves focus" test only checked our own handler ran, not
  that a competing (select2-shaped) handler on the same node was
  preempted — now binds a stand-in bubble-phase handler that would
  commit a selection, and asserts it never fires;
- the "listener removed on detach" test asserted only post-detach
  behaviour, which can't distinguish "listener removed" from "listener
  still installed but its target vanished" (the handler already
  early-returns without a button) — now asserts
  `searchFieldNode._twoManualEntryTabHandler` directly;
- the Escape test asserted only `defaultPrevented`, never that
  select2's `close()` was actually invoked — now spies on
  `$field.select2` and asserts it was called with `'close'`.

All three are mutation-verified this round: deleting `closeDropdown()`'s
body fails both the Shift+Tab and Escape tests; removing the forward-Tab
handler's `stopPropagation()` fails the Tab test.

`npx jest --config Test/Js/jest.config.js` — 21 suites, 249 tests, all
green.

Round-3 adversarial pass (Vader, against just the round-3 commit) found
the round-3 fixes were themselves incomplete in two places, plus one
more half-vacuous test:

- BUG: the removal-path resize nudge fired BEFORE `$existing.remove()`,
  not after — select2 measures `$dropdown.outerHeight()` synchronously
  when it handles `resize.select2.<id>`, so nudging first just
  re-measures the stale, still-taller geometry and the panel then
  shrinks under a position computed for the wrong height. Same defect
  class as round-2 finding #3; the fix landed at the wrong point in
  the sequence. Fixed: nudge now runs strictly after the DOM removal.

- BUG: forward Tab below MIN_INPUT_LENGTH (no button exists yet — the
  state the picker is in the moment it opens, and after every 1-2 char
  term) still fell through to select2's own handler, which
  `preventDefault()`s it regardless of whether anything is selectable —
  a WCAG 2.1.2 keyboard trap, in the PR whose entire subject is
  keyboard reachability. Fixed: the no-button branch now stops select2
  from seeing the key (`stopPropagation()` + `closeDropdown()`) but
  does NOT `preventDefault()` itself, so native Tab still advances to
  the next checkout field.

- NIT: the Shift+Tab branch was the one path in this module that didn't
  fail closed on a stale bind token (every other lookup here does).
  Added the same `getSearchFieldContainer($field, token)` staleness
  check used elsewhere, ahead of both the Shift+Tab and forward-Tab
  branches.

Test vacuity again, proved by mutation:
- the "detach" test only dispatched forward Tab, which has an
  early-return the Shift+Tab branch doesn't share — a leaked listener
  on just that branch would have passed. Added a same-test Shift+Tab
  dispatch.
- the button's own Tab/Shift+Tab handling (round 3's "one-way focus
  door" fix) had ZERO coverage — added a direct test.
- the whole resize-nudge apparatus (both paths, since round 2) had
  zero coverage. Added two tests that capture whether the button is
  actually in the DOM at the moment the nudge fires, not just that a
  resize event fired — which is what round 3's bug needed to be
  caught. Doing this exposed a real harness gap: `nudgeSelect2Resize()`
  targets `$(window)`, and the AMD test harness runs modules in an
  isolated vm sandbox whose `window` is a plain stub object, not the
  outer jsdom `window` — an identity check across that realm boundary
  never matched, so every resize nudge silently no-opped in every test
  ever written against this file. `Test/Js/company-search-manual-entry.test.js`'s
  mini-jQuery double now special-cases that cross-realm stand-in.

Mutation-verified this round: reverting the resize-nudge ordering,
reverting the no-button-Tab fix, deleting the removeEventListener call
in a Shift+Tab-specific way, and gutting the button's own keydown
handler each independently fail their respective new/strengthened
tests.

`npx jest --config Test/Js/jest.config.js` — 21 suites, 253 tests, all
green.

Subject: [PATCH 204/885] test(checkout): pin the stale-token guard and narrow
 the resize test-double patch (#30.x.15 round 4 polish)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Round-4 review (Vader, final pass) came back clean — no BLOCKER, no BUG
— but flagged two non-blocking coverage/robustness gaps on the round-4
commit, both cheap enough to close before merge rather than defer:

- the Tab handler's stale-bind guard (added this round, alongside the
  Shift+Tab and no-button fixes) had zero coverage; deleting just that
  guard line left the full suite green. Added a test that supersedes
  the bind without detaching and asserts the handler is inert against
  the button, focus and select2('close') — the exact gap the guard
  exists to close.
- the `$(arg)` mini-jQuery patch added to make `$(window)` observable
  across the AMD harness's vm sandbox boundary was an unguarded
  catch-all (`typeof arg === 'object'` routes ANY future opaque object
  to `window`). Narrowed to duck-type on `checkoutConfig`, the actual
  shape of the harness's sandboxed `window` stand-in, so anything else
  still falls through to an empty set as before.

Mutation-verified: deleting the stale-bind guard now fails the new
test (it passed, silently, before this commit).

`npx jest --config Test/Js/jest.config.js` — 21 suites, 254 tests, all
green.

 =?UTF-8?q?=E2=80=94=20open=20on=20any=20key,=20No=20matches=20found,=20Ta?=

Content-Transfer-Encoding: 8bit

TWO-25326 §1/§2/§4/§5/§7 for the Magento checkout surfaces (Luma, Amasty
OneStepCheckout and Fire Checkout share one code path — there is no
per-surface company-search JS or layout in this module).

- open on type: select2 4.1 only opens on Enter, Space and Alt+Down, so a
  buyer who focused the company field and started typing saw nothing.
  attachOpenOnType() opens on any single-character key and seeds it into
  the query field with a native input event, so the search fires on the
  first keystroke instead of swallowing it. Tab, navigation keys and
  modifier combinations are left alone.
- zero-result wording: the vendored bundle hardcodes English
  'No results found'. Both pickers now pass a shared language block with
  'No matches found' plus the existing threshold hint, so the two
  surfaces cannot drift.
- Tab is now a focus-MOVING operation, not just a closing one. Forward
  Tab out of the dropdown closes it and lands on the next control after
  the combobox; Shift+Tab lands on the previous one; Shift+Tab off the
  'not on the list' button steps back into the query field and leaves the
  dropdown open, the exact inverse of the forward shortcut. Every path
  falls through to the native key when there is no adjacent tab stop, so
  no state can trap the keyboard.
- company number on the address step: the hidden input's display:none
  scored (0,1,0) and lost to the theme's own .fieldset.address > .field
  rule at (0,3,0), so the 'Company Number' box was visible and looked
  editable on every one of the three surfaces despite the hide existing.
  Raised to !important, and the captured number now renders as a plain
  text label under the name field, end-aligned, only once a result has
  been selected and never in manual-entry mode.

comboboxElement() resolves select2's $selection both as the combobox
itself (what 4.1 actually returns) and as a wrapper around it; the
find()-only version silently resolved to nothing and every focus move
would have no-opped.

Tests: two new suites cover the open-on-type key matrix, the shared
wording and the label's three states against real jsdom nodes. The
existing CSS test only checked that a display:none rule existed, which
is why it passed throughout the period the field was visible; it now
pins the specificity that was the actual defect.

The tile rendered the same company three times: an editable company-name
control, a static "Company Number" caption, and the number itself below
that. §7 asks for one line, "Name (12345678)", between the term chips and
the order-intent notice.

The controls are HIDDEN, not removed, and that is the whole design of this
change. The tile's picker is the only company-capture surface for a buyer
on a saved address (no #shipping-new-address-form is rendered, and that is
the only selector address-autocomplete.js binds) or on a virtual cart (no
shipping step at all). Deleting it would leave those buyers no way to
supply a company, and Model/Two.php::authorize() then refuses the order
server-side — an order-blocking regression, not a cosmetic one. So the
control and the label swap: isCompanyCaptured() gates both, in opposite
directions, and no state shows both or neither.

Capture is gated on the NUMBER, not the name. A registry pick and
sole-trader autofill both yield one, so there is nothing left for the
buyer to do and the label takes over. Manual entry yields a name and no
number, and §6 says name-only must not make the payment method usable —
capture is precisely not complete, so the search box stays.

The superseded caption and its separate number span are removed outright
rather than hidden: unlike the input above them they were only ever a
DISPLAY of a value, and the new label is that display.

Knockout "visible" rather than "if" throughout, so the company-name node
stays in the DOM — the select2 binding, its MutationObserver rebinding and
the sole-trader write path all keep working untouched, and the readonly
binding still reads locked while hidden so re-entering the mode cannot
hand back an editable copy of a name the buyer must not edit.

Tests: 282 passing, 23 suites. The tile suite gained swap pins (both
visibility expressions are read out of the template and pinned to an exact
shape before being evaluated), a name-only case, and a position pin for
the between-chips-and-intent placement — that last one matters because the
label is inert display text, so nothing but a test would notice it
drifting. Six mutations run against the suite (label always visible, field
always visible, capture gated on name only, label drops the number,
readonly relaxed, label moved below the intent message); every one was
killed, and each was confirmed to have actually changed the tree first.

Regression introduced by the §7 swap in the previous commit, found in
adversarial review rather than by the tests written alongside it.

registeredOrganisationMode() never cleared the captured company. While the
tile's control was always on screen that was untidy but recoverable — the
buyer could simply search, and the pick overwrote the stale identity. Once
the control HIDES on capture it stops being recoverable: a buyer leaving
sole-trader mode faced a sole-trader label, no search box, and no route
back to either.

Clearing unconditionally is not the fix, and that is the trap here.
registeredOrganisationMode() is ALSO the tile's initialiser
(initObservable() calls it), so an unconditional clear would wipe a company
captured on the address step before the tile ever rendered — turning a
completed capture into an unpayable order, a strictly worse bug than the
one being fixed. The clear is therefore guarded on having actually been in
sole-trader mode, and the flag is read BEFORE it is flipped.

Both halves are pinned: leaving the mode restores the control, and the
init-path call leaves an upstream capture untouched. Three mutations run
(never clear, clear unconditionally, read the flag after the flip); all
three killed, each confirmed to have changed the tree first.

Also pins the picker's width option as a percentage literal. Hiding rather
than removing means select2 can initialise against an already-hidden node,
and select2's _resolveWidth returns anything outside its four keywords
verbatim — so '100%' resolves when the node is shown, whereas 'resolve' or
'element' would measure outerWidth() at init and freeze a hidden node's
search box at zero width. There is no way to observe that in jsdom, so the
option value itself is the pin.

Tests: 285 passing, 23 suites.

Subject: [PATCH 208/885] fix(checkout): discard the previous country's company
 on a country switch (TWO-24867)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

A buyer who mis-clicks the country, searches a company, then corrects the
country kept the first country's company. Three copies of it survived the
correction — the picker's own selection, the `companyData` customer-data
section the payment tile credit-checks, and the address autofilled from that
country's registry entry — and none of them describes the buyer's actual
country. The organisation number is the one that bites: it reaches the API
paired with the new billing country, is refused there, and surfaces as a
generic failure with nothing on screen naming the field that is wrong.

Ported from the PrestaShop fix, mechanism by mechanism:

- the address step's country `change` handler now retracts the company
  instead of only re-showing the field: it cancels the search still on the
  wire for the old country, reverts the autofilled address, and clears the
  name, the number and the published section;
- the payment tile drops its own selection when `countryCode` actually
  changes, so a stale organisation number cannot be submitted under the new
  country;
- `companyData` records the country it was captured in, and the tile refuses
  a record stamped with a country the buyer is no longer in. That covers the
  case an in-page reset cannot: the section is localStorage, so it outlives
  the page and the order.

Two deliberate divergences from PrestaShop, both pinned by tests rather than
left as claims. The picker is NOT re-bound — PrestaShop recreates its
autocomplete because that widget captures the country at construction, while
this one reads it per request, so the next search already carries the new
country and a re-bind would only drag a buyer in manual-entry mode back into
search mode. And the address revert is value-matched against a marker
`applyAddress()` records, so it clears only fields still holding exactly what
was autofilled; anything the buyer has since edited is left alone.

Also fixes, as part of the same handler: the `change` binding was
un-namespaced and re-bound on every `$.async` fire, so a re-rendered form
stacked one handler per render.

 the country-switch clear (TWO-24867)
MIME-Version: 1.0

Review round 1. A jQuery set is always truthy, so `$(...)?.text()` can never
short-circuit — reproducing the two sibling writers' `?.` implied a guard that
does not exist. `.text()` on an empty set is already the no-op that was wanted.

Subject: [PATCH 210/885] fix(checkout): tie the company tile label's
 visibility to the intent message's (TWO-25326)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Supersedes the gate shipped in PR #316. The label was shown whenever a
company number had been captured; the 2026-08-03 ruling on TWO-25326 is
that it is shown exactly when the inline order-intent message is shown
and hidden exactly when that message is hidden.

Both the label's `visible:` binding and the message's `ko if:` now call
one predicate, isOrderIntentMessageVisible(), rather than each testing a
condition of its own. That is deliberate: a parallel capture check would
agree with the message most of the time and diverge precisely in the
states the ruling asks about — a company captured with no intent placed
yet, a declined or errored intent, and a brand that suppresses the
notice.

The capture CONTROLS keep their own, unchanged gate on
isCompanyCaptured(): hidden once a company is captured, shown while one
is not. That rule is what preserves the only company-capture surface a
buyer on a saved address or a virtual cart has, so it is not folded into
the label's gate. A captured company with no approved intent on screen
therefore hides the controls and shows no label.

Verified by unit + mutation tests only. No browser verification — see
the PR description.

Subject: [PATCH 211/885] docs(checkout): name every state where the tile label
 cannot appear (TWO-25326)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Review round 1 on this PR. Three findings, no behaviour change.

The predicate's comment enumerated the states where the new gate diverges
from the superseded capture one, but omitted the two with the widest
reach: `enable_order_intent` off, where fillCompanyData() never calls
placeOrderIntent() at all, and a Dutch buyer whose company is not a BV,
where placeOrderIntent() early-returns a Deferred resolved with null. In
both the notice never appears, so under this ruling the company label
never renders either — for an intent-disabled merchant that is the whole
storefront. Both now named in the comment, both pinned by a test so they
read as decisions, and the brand-overlay guide's
intent_approved_notice_enabled row says the switch also suppresses the
label.

Also adds the missing case for the companyName clear subscription.
Verified by mutation that deleting it left the suite green: every other
route writes both observables, so the companyId subscription alone
satisfied them, and the hand-edited-name fail-closed path that
initOrderIntentApprovedNotice()'s own comment calls load-bearing had no
coverage.

Also corrects an overclaim in the test file's header. Both bindings
resolve to the same predicate, so the paired message/label assertions
cannot disagree by construction; they are a readability aid, and the
string-equality pin is what actually forbids two expressions that merely
agree.

Subject: [PATCH 212/885] docs(checkout): say plainly that the tile can now
 show no company number (TWO-25326)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Review round 2 on this PR. No behaviour change.

The template comment beside the removed Company Number caption still
claimed §7 "replaced" it with a single label higher up the tile. That is
no longer accurate: since the label only renders while the intent message
renders, every state where the notice is absent — no intent placed yet,
declined, errored, a notice-suppressed brand, order intent off, a Dutch
non-BV buyer — leaves the captured organisation number displayed nowhere
on the payment tile. The address step's own Company Number field is
visually hidden too, so there is no second surface picking it up. The
comment now says so, and names giving the label a second capture-based
route as a ticket decision rather than a tidy-up.

Also renames the test that claimed to pin the Dutch non-BV route. Verified
by mutation that neutering the NL/BV early return leaves the whole suite
green: nothing in the file touches billingAddress or BVCompanyRegex, so
the test pins the falsy branch of processOrderIntentSuccessResponse and
nothing more. It is the sole catcher of that branch, so it stays — under
a name that matches what it does, with a note on what pinning the route
itself would need.

Also records what the undefined guard trades for not throwing: a binding
evaluated before initOrderIntentApprovedNotice() would register no ko
dependency and hide both elements permanently rather than failing loudly.
Unreachable today; a future refactor that defers the wiring would hit it.

Pick a company on the Luma/Amasty/Fire address step and the organisation
number appears under the name field; reload, and the name is still there
while the number is gone.

Magento persists the address form through the checkoutProvider: shipping.js
listens for changes on its `shippingAddress` data, writes them to the
`checkout-data` localStorage section, and on the next load pushes the whole
saved object -- `custom_attributes` included -- back into the provider before
the fields render. The provider is therefore the persistence boundary, and
only a value it has seen is restored.

The company NAME crosses that boundary for free: select2 fires a native
`change` when a result is picked, which is exactly what `ui/form/element/
input`'s `value:` binding listens on, and the element's `value` observable is
two-way linked to its provider path. The company NUMBER had no such route --
it is written by us rather than by a widget, and a jQuery `.val()` write
raises no event Knockout listens for. The provider never learned the number,
so nothing was saved and there was nothing to restore.

Route the number's write through the UI component as well, which is what
publishes it to the provider, and re-render the text label when the component's
value changes so a restore that lands after the form initialises still paints.

+ * See COPYING.txt for license details.
+ *
+ * TWO-25326 §5, address step (Luma / Amasty OneStepCheckout / Fire Checkout —
+ * one code path): the captured organisation number must survive a PAGE RELOAD,
+ * exactly as the company name does.
+ *
+ * The reported bug: pick a company, the number appears under the name field,
+ * reload, and the name is still there while the number is gone.
+ *
+ * Why that happened, and therefore what this file has to model. Magento
+ * persists the address form across loads through the `checkoutProvider`:
+ * `Magento_Checkout/js/view/shipping.js` listens for changes on the provider's
+ * `shippingAddress` data and writes them to the `checkout-data` localStorage
+ * section, and on the next load pushes the whole saved object —
+ * `custom_attributes` included — back into the provider before the fields
+ * render. So the provider is the persistence boundary. The company NAME
+ * crossed it for free (select2 fires a native `change`, which is what
+ * Knockout's `value:` binding listens on); the company NUMBER was written with
+ * a bare `$(…).val()`, which raises no event Knockout listens for, so the
+ * provider never learned it, nothing was saved, and there was nothing to
+ * restore.
+ *
+ * That boundary is the whole subject here, so it is modelled rather than
+ * mocked away: a provider that notifies, a `shipping.js`-shaped saver behind
+ * it, a storage bag that outlives the "page", a UI component whose `value`
+ * observable is two-way linked to the provider (as `Magento_Ui/js/form/element/
+ * abstract` is), and a Knockout-shaped mirror of that observable into the DOM
+ * input. `reload()` then throws away the DOM, the component and the module
+ * instance, keeping only the storage bag — so a test that passes here cannot
+ * be passing on in-session state.
+ *
+ * LIMITATIONS — read before trusting a pass.
+ *
+ *  1. Company search is left OFF in these tests, so select2 is never really
+ *     bound and search mode is asserted by putting the `select2` data key on
+ *     the name input, the same convention as address-company-id.test.js. What
+ *     that costs: on a real reload the picker's own bind ALSO calls
+ *     `renderCompanyIdText()`, so these tests exercise the company-number
+ *     field's own render paths in isolation. That is deliberate — those are the
+ *     paths that have to hold when the number resolves after the picker — but
+ *     it means a regression that only broke the picker-side render would not
+ *     fail here.
+ *  2. The saver models `shipping.js`'s change→localStorage step, not its
+ *     street-not-empty guard. A real checkout with no street typed yet persists
+ *     nothing at all, name included.

+         * Magento persists the address form by listening for changes on the
+         * `checkoutProvider`'s `shippingAddress` data
+         * (`Magento_Checkout/js/view/shipping.js` → `checkoutData
+         * .setShippingAddressFromData`), writes them to the `checkout-data`

+         * the fields render. So the provider is the persistence boundary, and
+         * only a value the provider has SEEN is restored.
+         *
+         * The company NAME crosses that boundary for free: select2 fires a
+         * native `change` on the input when a result is picked, `ui/form/
+         * element/input`'s `value:` binding reads the DOM on `change`, and the

+         * The company NUMBER had no such route — it is written by us, not by a
+         * widget, and a jQuery `.val()` write raises no event Knockout listens
+         * for. The provider therefore never learned the number, nothing was
+         * saved, and there was nothing to restore.
+         *
+         * Writing through the component is what publishes to the provider; the

+         * value straight off the DOM in the same tick.
+         *

+         * that would also fire our own change handler, which republishes the
+         * `companyData` customer-data section — and the payment step reads a

Subject: [PATCH 214/885] test(checkout): pin the number label to the
 component, not to the input

Knockout's own `value:` binding and the label's re-render are two subscribers
on the same observable; which runs first is a Knockout internal, so the display
read must not depend on the input having caught up.

Four findings from round 1, and one declined with a reason.

- setCompanyIdValue() wrote the component before the input. The component
  notifies synchronously and the label renders from a subscriber that reads the
  input first, so the previous company's number was painted for the rest of the
  tick -- and a number was painted at all while clearing. Input first.
- watchCompanyIdComponent() guarded on a flag, so only the FIRST view instance
  ever subscribed and every superseded one was retained for the life of the page
  by that subscription's closure. Dispose and re-take instead, so the live view
  is the one that renders and nothing stacks.
- The restored number carries no country stamp, while the companyData section
  does, so a number captured in another country could be restored and
  credit-checked under the address now on screen -- the TWO-24867 failure, via a
  route onCountryChanged cannot reach. Guarded on restore, failing open on an
  unstamped record exactly as the payment step's own guard does.
- The stacking test was vacuous: renderCompanyIdText() removes existing labels
  before appending, so N stacked subscribers still produce one label and a label
  count cannot detect stacking. It now asserts the subscription count.

Declined: re-deriving editability from the subscriber. It fires on the buyer's
own change too, and the derivation reads the field's own value, so it would
disable the field the moment they blurred it.

Subject: [PATCH 216/885] test(checkout): make the write-order test able to
 fail

Knockout's DOM mirror is registered before the module's own subscriber and
updates the input first, so with the mirror running the assertion held whichever
way round setCompanyIdValue()'s two writes went. Suppress the mirror and observe
the label the notification actually paints.

Subject: [PATCH 217/885] fix(checkout): the country guard has to hold on the
 late-restore path too (TWO-25326)

Round 2. The guard ran once, from the company-number field's $.async resolve,
and returned immediately on an empty field -- which is the state that path always
sees when the provider push lands after it. So a number captured in another
country was discarded on the early-restore ordering and waved through on the late
one, i.e. the check was dead on exactly the ordering the value subscription
exists for.

Guard from the subscriber as well. Re-entrant and terminating: the clear notifies
the same subscribers, and the second call returns on the now-empty field.

Also from round 2: guard the dispose() call the way every other registry access
in this file is guarded, and state in the docblock that reading the country off
the select depends on the select already holding the restored country -- with
what holds that up, and what the symptom would be if it ever stopped holding.

Subject: [PATCH 218/885] fix(checkout): the country guard must read the same
 pair the render does (TWO-25326)

Round 3. The guard read the input alone while the render it now runs immediately
before reads input-then-component -- so on the one ordering where the two
disagree, which is precisely the ordering the render refuses to assume, the guard
bailed out and the number it declined to check was then painted and left in the
provider to be credit-checked under the wrong country.

Reading the same pair also makes the re-entrant clear terminate on either write
order rather than only on input-first.

Two round-3 lows recorded in comments rather than guarded: termination no longer
depends on the write order (said in the docblock), and a hand-typed number gets
checked against the previous company's stamp -- unreachable while the field is
CSS-hidden.

Subject: [PATCH 219/885] docs(checkout): say what re-entrant termination
 actually rests on (TWO-25326)

Round 4, comment-only. The docblock claimed termination held under either write
order; under a component-first write it would rest on Knockout suppressing a
same-value notification, which is a different mechanism and a second reason to
keep the order as it is. Also drops a redundant null assignment.

Subject: [PATCH 220/885] fix(checkout): dispose fillCustomerData()
 subscriptions to stop stacked order_intent POSTs

TWO-25347: fillCustomerData() subscribes to four shared quote/customerData
singletons on every call and never disposed the previous set, so a
re-render (Luma/Amasty on shipping changes, Fire Checkout on every
totals/shipping change) stacked N subscriptions and fired N concurrent
order_intent POSTs for a single company pick.

- dispose() now tears down fillCustomerData()'s subscriptions, mirroring
  the existing _twoVisibilitySub pattern.
- fillCompanyData() adds a belt-and-braces in-flight guard so a second
  concurrent call for the SAME captured company cannot re-fire
  placeOrderIntent() even if another undisposed path re-enters it.

Aligns Magento (Luma/Amasty/Fire, one shared code path) with the WC/PS/Hyvä
company-capture pattern per Doug's 2026-08-03 design ruling:

§6a — gating alignment. The Two payment method stays selectable with a
manual (name-only, no organisation number) capture, but submit is now
blocked with a visible message ("Please select your company before paying
with %1.") instead of the previous silent no-op (no block, no message, no
order).

Two bugs found investigating the silence, both fixed:
- gateway_method.js's SCHEMA_ERROR error-handling branch reassigned a
  `const message`, which threw and silently swallowed the message this path
  exists to show. Changed to `let`.
- order_intent 400s on every free-shipping cart: the SHIPPING_FEE line
  divided shipping_tax_amount by a zero shipping_amount, sending
  `tax_rate: "NaN"`. Now resolves to `0.000000` when shipping is free.

§7.1 — one shared company-search control, location set by admin setting.
The existing `enable_company_search` setting already gated the address-area
control; the payment tile's OWN instance of the same widget was previously
unconditional. It now binds only when the tile is the active location —
the setting is off, or the checkout has no address-area host for it (saved
address, virtual cart).

§7.2/§7.3 — text-only tile, standalone label removed. The pre-ruling
`.two-company-label` element and its companyDisplayLabel() builder are
removed, not relocated: company name/number now appear only embedded
inside the order-intent notice sentence itself —
  Approved: "This order by <name> (<number>) is likely to be accepted by Two"
  Not approved: "Two is not available for this order by <name> (<number>)"
A clean "not approved" response now renders as a persistent tile notice
(mirroring the approved notice's mechanism) instead of a toast that a
later checkout update would wipe.

§7.4 — audited the private brand-overlay repo for this platform (read-only
reference, not modified): its brand config already suppresses the whole
intent-message surface (approved and declined) for that brand, so there is
no vanilla-string override risk today. The new per-notice copy-override
mechanism (getIntentApprovedNotice() / getIntentDeclinedNotice(), both
independent) is in place for any future brand that re-enables the notice
with its own wording.

Test coverage: JS (Jest) mutation-verified for the §6a gate, the tile
location gate, and both notices' independent gating/wording/clearing; PHP
(PHPUnit) mutation-verified for both notice-copy resolvers.

 /**
- * The 2026-08-03 ruling on TWO-25326, which supersedes §7's own gate: the label
- * is shown exactly when the inline order-intent message is shown, and hidden
- * exactly when it is hidden.
- *
- * "Exactly when" is asserted two ways, because either alone is weak:
+ * TWO-25326 §7.3 (2026-08-03 ruling): each notice is gated on its OWN
+ * observable via a `ko if`, and each observable is set exactly once the
+ * corresponding order-intent outcome is known. There is no longer a shared
+ * "the label follows the message" predicate to pin, because there is no
+ * label — company display and intent outcome are now the SAME element.
  *
- *  - as SOURCE: the two bindings must be the identical expression. Two
- *    different expressions that agree in the states a test happens to visit is
- *    the precise defect the ruling forbids, and no set of behavioural cases can
- *    rule it out.
- *  - as BEHAVIOUR: across every state that separates the new gate from the old
- *    one — captured-but-no-intent, declined, errored, brand-suppressed notice,
- *    order intent disabled, Dutch non-BV buyer — the label follows the message
- *    rather than capture.
- *
- * Be honest about the division of labour there. Because both bindings resolve
- * to the SAME predicate, the paired `intentMessageVisible()` /
- * `labelVisible()` assertions cannot disagree by construction — they are a
- * readability aid, not independent corroboration. The string-equality pin is
- * what actually forbids two expressions that merely agree; the behavioural
- * cases are what forbid the predicate being the wrong one.
- *
- * The behavioural cases are the mutation-sensitive half: each of them had the
- * label VISIBLE under the superseded `isCompanyCaptured()` gate, so reverting
- * the template one-liner fails them.
+ * The behavioural cases are the mutation-sensitive part: each of them
+ * exercises a state that a naive "captured ⇒ show something" gate would get
+ * wrong (captured-but-no-intent, declined, errored, brand-suppressed,
+ * order-intent-off, Dutch non-BV, edited company).

-            — between the term chips and the order-intent notice
-            (TWO-25326 §7). Canonical placement across all four platforms.
+            TWO-25326 §7.3 (2026-08-03 ruling): the standalone
+            `.two-company-label` text that used to sit here is REMOVED, not
+            supplemented. The captured company name/number are now shown
+            ONLY inside the order-intent notice sentence itself — see
+            ConfigProvider::getOrderIntentApprovedNotice() /
+            getOrderIntentDeclinedNotice() for the copy templates and
+            resolveCompanyNotice() in gateway_method.js for the substitution.
+            A company captured with no intent outcome yet showing renders
+            neither notice below and therefore displays the company nowhere
+            in the tile — that follows from "the notice is the only display
+            surface" and is the ruling, not an oversight.
 
-            Shown exactly when the order-intent message below is shown, and
-            hidden exactly when it is hidden (TWO-25326, 2026-08-03) — which is
-            why both bindings call the SAME predicate,
-            isOrderIntentMessageVisible(), rather than each testing its own
-            condition. This supersedes the earlier rule that gated the label on
-            a captured company number.
-
-            It is NOT a swap with the tile's company controls. Those are
-            hidden/shown on isCompanyCaptured() and that rule is unchanged, so
-            a company captured with no approved intent showing hides the
-            controls and shows no label. See isCompanyCaptured() in
-            gateway_method.js for why the controls are hidden rather than
-            removed — the tile is the ONLY company-capture surface for a buyer
-            on a saved address or a virtual cart, and deleting it would block
-            those orders outright.
-
-            `visible:`, not `if:`, deliberately. `if:` would tear the node out
-            of the DOM and rebuild it on every change; the node here is inert
-            display text, and keeping it stable costs nothing while avoiding
-            any interaction with the MutationObserver-based rebinding the
-            company picker relies on.
-
-            One element, one binding, so there is no caption/value split to
-            fall out of step and no punctuation glued outside a translated
-            string — companyDisplayLabel() builds the whole string in one
-            place. The element carries no `name` and no writable binding: it
-            displays companyName()/companyId() and never writes either.
-            getData() still reads those observables, never the DOM.

Four real defects found in a 4-persona adversarial review of PR #321 before
merge, all fixed here:

1. BLOCKER — a declined order_intent left a buyer with NO recovery control.
   processOrderIntentSuccessResponse()'s declined branch does not clear
   companyName/companyId, so isCompanyCaptured() stays true and the tile's
   capture control (gated on `!isCompanyCaptured()`) stayed hidden — a dead
   end without a page reload on any checkout where the tile is the buyer's
   only route (saved address, virtual cart, or the location setting off).
   The field now also re-shows when the declined notice is visible.

2. BLOCKER — the tile's company-search widget never re-bound on an
   address-type switch. enableCompanySearch() only ran from three call
   sites, none of which fire when a buyer moves between a NEW and a SAVED
   shipping/billing address — exactly the DOM change
   isTileCompanySearchActive() depends on. updateShippingAddress() /
   updateBillingAddress() now call a new refreshTileCompanySearchBinding()
   unconditionally.

3. BLOCKER — the order_intent in-flight guard could stick permanently true.
   placeOrderIntent() can throw synchronously (a transient null
   quote.billingAddress()), which skipped `.always()` entirely and left
   `_orderIntentInFlightFor` set forever for that company — every later
   pick of the same company would silently no-op. Wrapped in try/catch,
   mirroring placeOrderBackend()'s existing rescue shape.

4. BLOCKER — a cross-company race could misattribute an order-intent
   verdict. The in-flight guard only dedupes the SAME company; a stale
   response for a previously-selected company could land after the buyer
   picked a different one, and the notice resolvers read
   companyName()/companyId() live at settle time. Both success and error
   handlers now confirm the observables still match the request before
   writing either notice.

Also: broadened the free-shipping tax_rate NaN guard to non-finite
shipping_amount values (not just exactly zero), and removed the
`orderIntentDeclinedMessage` config key/property, which was dead — never
read anywhere, with a comment claiming otherwise.

All four review-found defects are covered by new, mutation-verified tests.

Two personas independently re-reviewed round 1's fixes. Both flagged the
same defect in the synchronous-throw fix, and one found a real gap in the
decline-recovery fix that only reproduces on a specific brand config:

1. BLOCKER — the round-1 fix for the synchronous-throw guard-lock (catch,
   clear the guard, rethrow, mirroring placeOrderBackend()) still rethrew
   into callers with no catch and mandatory follow-up work. Worst case:
   fillCustomerData() calls the one-shot company read BEFORE wiring the
   shippingTelephone/countryCode/shippingAddress/billingAddress
   subscriptions — a throw from that one-shot read aborts the function
   mid-setup and permanently skips all four subscriptions for the rest of
   the checkout session. Same hazard skips updateAddress()'s
   project/department writes and refreshTileCompanySearchBinding(). The
   catch now logs, shows a buyer-facing message, and does NOT rethrow —
   the guard-clear (the fix's actual goal) doesn't need the rethrow at all.

2. BUG — the decline-recovery re-show (round 1) was gated on
   isOrderIntentDeclinedNoticeVisible(), but `enable_order_intent` and
   `<intent_approved_notice_enabled>` are independent brand.xml switches:
   a brand can have order_intent firing for real while the notice UI is
   suppressed, in which case the declined notice's text is permanently
   empty and the gate never re-opens the field — reproducing the exact
   dead-end the fix existed to close, for that brand config. Added a
   notice-independent `orderIntentDeclined` observable, set on every
   decline regardless of whether any notice text was produced, and gated
   the field's re-show on that instead.

Both fixes are covered by new, mutation-verified tests, including one
pinning the specific "notice suppressed" scenario for #2.

Subject: [PATCH 225/885] fix(checkout): remove brand-override hook for the
 declined intent notice
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

2026-08-04 ruling (TWO-25326): the buyer-facing "order intent NOT
approved" checkout notice must never be brand-overridable — every
brand renders the exact same platform default copy. PR #321 added a
fully-wired getIntentDeclinedNotice() override (interface, brand.xml
element, loader, descriptor, registry, ConfigProvider) mirroring the
approved-notice override; that mirroring was the mistake this reverses.

- Drop BrandRegistryInterface::getIntentDeclinedNotice() and every
  implementation (DescriptorBackedBrandRegistry, deprecated Brand,
  Descriptor).
- Model\Brand\Loader stops parsing <intent_declined_notice> and now
  hard-fails with a clear DomainException if a brand.xml declares it,
  so a stray overlay element is caught rather than silently ignored.
- Drop the <intent_declined_notice> element from brand.xsd.
- ConfigProvider::getOrderIntentDeclinedNotice() always renders the
  literal default copy; no override branch.
- Update brand-overlay-guide.md and the unit test suite to document
  and lock in the "approved is overridable, declined never is" split.

The approved-notice override (getIntentApprovedNotice()) is unchanged
and correct — brand overlays are still expected to use it.

 earlier standalone `.two-company-label` element is gone, not relocated.

Leak-gate fix — the previous commit's brand-overlay-guide.md update
said 'ABN-style overlay' twice. This is the public magento-plugin
repo; partner/brand names belong only in that brand's own private
overlay repo. Reworded to 'brand overlay' / 'white-label brand
overlay', no functional change.

Subject: [PATCH 227/885] refactor(checkout): consolidate company-search
 select2 wiring into one class
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

TWO-25326: address-autocomplete.js and gateway_method.js each rolled their
own select2({...}) construction, dropdown open/close wiring, manual-entry
button, and "Search for company" link — two parallel implementations of
the same picker, drifting further apart with every fix. Mirrors
PrestaShop's TwoCompanySearch: a single CompanySearchControl class
(view/frontend/web/js/model/company-search-control.js) now owns that
lifecycle end to end, built on the existing shared primitives in
company-search.js. Each surface constructs exactly one instance and wires
only the mount-specific glue (selectors, onSelect, manual-entry outcome).

Updated Jest coverage to load the real control alongside company-search.js
wherever a test drives the select2 wiring directly, and retargeted the two
structural (source-grep) suites at the class now that the wiring moved out
of the two surfaces.

+ * TWO-25326: the single class that owns the company-search picker's full
+ * lifecycle end to end — select2 construction, dropdown open/close wiring,
+ * the manual-entry button, the "Search for company" return link, and
+ * open-on-type — built on top of the shared, mount-agnostic primitives in
+ * `company-search.js` (the search request, result mapping, address

+ *
+ * Mirrors PrestaShop's `TwoCompanySearch` class: ONE implementation of the
+ * select2 wiring, configured entirely through the constructor options
+ * below, never duplicated per mount. `address-autocomplete.js` (shipping
+ * step) and `gateway_method.js` (payment tile) each construct exactly one
+ * instance of this class rather than each rolling their own `.select2({…})`
+ * call — see those two files' `enableCompanySearch()` for the call sites.
+ *
+ * Magento's checkout is more dynamic than PrestaShop's: a payment renderer
+ * is pushed once PER Two-family brand (so a checkout offering two brands has
+ * two independent tile widgets alive at once), and which mount — address
+ * area or tile — is the buyer's active route to search can flip at runtime
+ * (virtual cart, saved address) without a page reload. Those two facts are
+ * why this stays two call sites rather than PrestaShop's one
+ * `TwoCheckoutManager`-owned singleton: each call site is a different
+ * Knockout component with its own dispose() lifecycle already scoped to
+ * "the widget THIS component bound", and forcing a page-wide singleton would
+ * fight that existing multi-brand safety model rather than simplify it. The
+ * mutual-exclusion invariant PrestaShop gets from a single decision point,
+ * Magento gets from the existing `isCompanySearchEnabled` /
+ * `isTileCompanySearchActive()` guards each call site already checks before
+ * constructing or (re)binding its instance — at most one of the two mounts
+ * is ever actively bound to a live select2 widget for a given brand at a

Subject: [PATCH 228/885] fix(checkout): tile company-search control stays
 visible; add org-number label
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

TWO-25326, 2026-08-04 ruling — deliberately supersedes the 2026-08-03
(§7.3) capture-state/decline-recovery gating this replaces, per explicit
sign-off: the tile's company-search control's visibility is controlled
ONLY by the "enable search in address" admin setting
(isTileCompanySearchActive()), never by capture state or order-intent
outcome.

Bug A: the field's `visible:` binding no longer reads isCompanyCaptured()
or isCompanyRecoveryNeeded() (now deleted, along with the now-dead
orderIntentDeclined observable it was the only reader of) — it depends on
isTileCompanySearchActive() alone. Previously the control hid on capture
and only re-showed on a declined order intent, so an approved intent left
it hidden permanently with nothing to bring it back.

Bug B: a `.two-company-id-text` org-number label now renders under the
tile's control once a company is captured, mirroring
address-autocomplete.js's renderCompanyIdText() (§5) — the address-step
and tile mounts now behave consistently. This is NOT a reinstatement of
the `.two-company-label` line §7.3 removed (a combined name+number line
gated on notice visibility); the order-intent notice sentence is
unaffected.

Test/Js/tile-company-readonly-fields.test.js updated: the GATE PINS group
now pins `isTileCompanySearchActive()` and the new label's gate
separately, and every capture-mode test asserting the control disappears
is rewritten to assert it stays up.

  *
- * This supersedes three earlier shapes in turn. TWO-25288 first made the
- * captured number a read-only `<input>`; the ruling after that replaced the
- * input with a "Company Number" caption plus a separately-rendered value.
- * §7 (pre-2026-08-03) replaced that pair with one `.two-company-label` line,
- * gated on the intent message's own visibility. The 2026-08-03 ruling
- * removes that label too — company display now lives ONLY in the notice
- * text, not beside it.
+ *  - Bug A: the capture CONTROL's (the field + picker) visibility is no
+ *    longer gated on isCompanyCaptured() or on any order-intent outcome at
+ *    all. Doug's exact words: it "is controlled ONLY by the state of the
+ *    'enable search in address' admin setting ... and search control
+ *    visibility is not changed for any other reason" — i.e.
+ *    isTileCompanySearchActive() alone. Previously it hid on capture (the
+ *    theory being that the notice sentence made a second, editable copy
+ *    redundant) and briefly grew a decline-recovery carve-out
+ *    (isCompanyRecoveryNeeded(), now deleted) to avoid trapping a declined
+ *    buyer — found in testing to still leave the control gone, permanently,
+ *    on the common approve path.
  *
- * The control is HIDDEN, not deleted, and that distinction is pinned here
- * deliberately. The tile's picker is the only company-capture surface for a
- * buyer on a saved address (no `#shipping-new-address-form` exists, and that
- * is the only selector address-autocomplete.js binds) or on a virtual cart
- * (no shipping step at all). Deleting it would block those orders outright.

- *     equality between the two bindings, not as two matches against one
- *     pattern, because two different expressions that both happen to be true

+                    capture-state and decline-recovery gating that used to
+                    live in this comment — Doug's exact words: "the search
+                    control ... is controlled ONLY by the state of the
+                    'enable search in address' admin setting: if true,
+                    search control is rendered inside the address block,
+                    otherwise is rendered inside the payment tile — and
+                    search control visibility is not changed for any other
+                    reason").
 
-                    Also hidden whenever isTileCompanySearchActive() is
-                    false — i.e. the admin setting puts the shared
-                    company-search control in the address area AND that
-                    address-area control actually exists on this checkout.
-                    The tile is then a display-only surface; showing this
-                    editable field too would be the "two bespoke
-                    implementations" the 2026-08-03 ruling forbids. See
-                    isTileCompanySearchActive() in gateway_method.js for the
-                    saved-address/virtual-cart fallback that keeps it true
-                    (and this field visible) even with the setting on.
+                    So this field's visibility depends on ONE thing —
+                    isTileCompanySearchActive(), the live read of that single
+                    admin setting (plus the saved-address/virtual-cart
+                    fallback documented on that method in gateway_method.js,
+                    which is the SAME condition, not a second one). It no
+                    longer depends on isCompanyCaptured() or on any
+                    order-intent outcome: the control stays visible after a
+                    company is picked, whether the subsequent order-intent
+                    call approves, declines, or errors. The org-number label
+                    below (not the notice sentence) is now the one thing that
+                    changes on capture.
 
-                    NOT removed, only hidden. This field and the picker bound
-                    to it are the buyer's company-capture route whenever the
-                    tile IS the active location — see isCompanyCaptured() and
-                    isTileCompanySearchActive() in gateway_method.js.
-                    `visible:` also keeps the node in the DOM so the select2
-                    binding, its MutationObserver rebinding and the
-                    sole-trader write path all keep working untouched; `if:`
-                    would destroy and rebuild the node under them.
+                    The previous behaviour hid this field once
+                    isCompanyCaptured() went true, on the theory that the
+                    order-intent notice sentence made an editable, visible
+                    control redundant — and only re-showed it on a decline,
+                    via isCompanyRecoveryNeeded(), to avoid a dead end for a
+                    buyer with no other route to pick a different company.
+                    Doug found this INCORRECT in live testing on 2026-08-04:
+                    the control was disappearing when a company was picked
+                    and, on the common path (order intent approves), never
+                    coming back — with nothing marking that as intentional
+                    from the buyer's side. This ruling removes that coupling
+                    entirely rather than patching it again.
 
-                    Hiding also takes this `required` input out of jQuery
-                    Validation's way, which only matters in the direction that
-                    helps: `elements()` skips hidden fields, and both states
-                    where this is hidden are states where the buyer either
-                    already captured a company here or has another control
-                    (the address-area one) to do it with.
+                    `visible:`, not `if:`, for the same reason as before:
+                    it keeps the node in the DOM so the select2 binding, its
+                    MutationObserver rebinding and the sole-trader write path
+                    all keep working untouched; `if:` would destroy and
+                    rebuild the node under them.
 
-                    RE-SHOWN on a decline, even though isCompanyCaptured() is
-                    still true then (found in adversarial review, 2026-08-04):
-                    processOrderIntentSuccessResponse()'s declined branch does
-                    NOT clear companyName/companyId — only an approval's own
-                    company-change subscriptions do that. Gating on capture
-                    alone left a declined buyer looking at a persistent "not
-                    available for this order" notice with NO control anywhere
-                    on the tile to pick a different company — a dead end
-                    without a page reload on exactly the checkouts where the
-                    tile is the buyer's ONLY route (saved address, virtual
-                    cart, or the setting off).
-
-                    isCompanyRecoveryNeeded(), NOT isOrderIntentDeclinedNoticeVisible()
-                    — round 2 of the same review found gating this on the
-                    NOTICE's own visibility reproduced the dead-end for any
-                    brand with order_intent enabled but the notice UI
-                    suppressed (two independent brand.xml switches), since
-                    that brand's notice text is permanently empty even on a
-                    real decline. isCompanyRecoveryNeeded() is set on every
-                    decline regardless of whether any notice text exists.
-                    Picking a new company clears both AND completes capture,
-                    so the field hides again once there is something new to
-                    hide it for.
+                    Hiding (when isTileCompanySearchActive() is false) also
+                    takes this `required` input out of jQuery Validation's
+                    way — `elements()` skips hidden fields, and that state is
+                    exactly the one where the buyer has the address-area

Subject: [PATCH 229/885] fix(checkout): tile org-number label a11y + stale
 docs + vacuous test pin
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Review round on PR #324 found three real issues in the tile's
.two-company-id-text label (TWO-25326, 2026-08-04 ruling):

- The label had no accessible name, unlike address-autocomplete.js's
  renderCompanyIdText() which pins one for exactly this reason — a bare
  number is unreadable to a screen reader. Add the same aria-label.
- nameFieldVisible() in the test suite pinned the visible: binding by an
  unanchored, prefix-only regex and then returned a hardcoded value
  instead of evaluating the expression, so a reintroduced suffix
  conjunction (e.g. the old capture-state gate) passed silently. Anchor
  the match and evaluate it against the renderer, same discipline as
  companyIdLabel(); also add an aria-label pin to companyIdLabel() so a
  dropped accessible name fails the suite too.
- ConfigProvider.php and brand-overlay-guide.md each still claimed the
  order-intent notice is the ONLY place the company name/number render in
  the tile — false since this PR added the org-number label as a second,
  notice-independent surface. Qualify both to NAME vs NUMBER.

Subject: [PATCH 230/885] fix(checkout): finish NAME/NUMBER doc split on
 remaining stale claims
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Round 2 review found two more instances of the same stale "notice is the
ONLY display surface" claim that the previous commit fixed in
ConfigProvider.php and brand-overlay-guide.md, but missed here:

- gateway_method.html's own top-of-block comment (~235 lines above the
  new .two-company-id-text label it now contradicts) still asserted a
  captured company with no intent outcome shows nowhere in the tile —
  false since the new label renders the NUMBER in exactly that state.
- tile-company-readonly-fields.test.js's "standalone label is gone" test
  comment said the same thing.

Both now split NAME (notice-only, unchanged) from NUMBER (also the new
label, notice-independent), consistent with the earlier fix.

Round 3 review found one more surviving instance of the "notice is the
ONLY surface company info shows on" claim, in approvedNoticeVisible()'s
own docblock — missed by the previous two doc-fix commits because it's a
different helper than the ones already touched. Same NAME/NUMBER split.

Also ran a full repo-wide grep for "only place/surface/display" +
"nowhere in the tile" variants across php/js/html/md; no other survivors.

Subject: [PATCH 232/885] fix(checkout): tie order-intent loader dismissal to
 all in-flight requests

TWO-25326: on Amasty OneStepCheckout and Fire Checkout the full-screen
loader shown during an order_intent check was dismissed before the
call actually resolved. Both re-render this payment renderer on
totals/shipping changes, so a re-render mid-flight spins up a fresh
instance that independently fires its own order_intent POST for the
same company while the orphaned previous instance's request is still
outstanding; whichever settled first hid the shared loader early.

Moves the startLoader()/stopLoader() pairing to a module-scope
reference count (mirroring the existing placeOrderInFlight pattern in
this file), so the loader only hides once every outstanding
order-intent request has settled. Luma is unaffected since it never
re-renders mid-flight and the count never exceeds one.

Subject: [PATCH 233/885] fix(api-key): differentiate verification failures and
 gate checkout on them
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

A configured API key was treated as a working one, and every non-200
verification outcome was reported identically as "API key is not valid".
Two consequences: an admin whose store could not reach the API was told
their key was wrong and went looking for the wrong fix, and a buyer could
select the payment method on an integration that could not work, meeting
the failure at order placement instead of at selection.

Add Service\Merchant\ApiKeyStatus, which categorises the verification
outcome into buckets an admin can act on — rejected key (401/403),
service error (5xx), unreachable (no HTTP exchange completed at all),
other non-2xx, malformed 2xx, and not configured — and caches the
verdict following the protocol the sibling providers in that namespace
already use: keyed on a hash of the API key so a key swap re-verifies
immediately, successes cached for 5 minutes, failures for 1 minute so an
outage cannot put a live timing-out call on every checkout render.

Wire it into all three former call sites:

- The admin panel renders category-specific wording, and no longer
  echoes the upstream response body next to it. It verifies live and
  writes the result forward into the shared cache, so a key corrected on
  that page takes effect at checkout immediately.
- Two::isAvailable() withdraws the payment method on any failure
  category, before the Amasty bypass (which defers only the
  minimum-order gate, and must not defer this one).
- Model\Ui\ConfigProvider emits no checkout-config subtree at all on a
  failure. That is the gate the company-search control mounts behind, so
  withholding it withholds company search as well as the payment tile —
  the same job the sibling plugins do by withholding their client-side
  bootstrap object. It also removes a live HTTP call that previously ran
  on every checkout render.

Service\Api\Adapter keeps the real HTTP status on an empty-bodied
non-2xx response instead of letting its catch-all discard it. Without a
status, an empty-bodied 5xx is indistinguishable from a transport
failure, so a service outage was reportable only as "could not be
reached". The returned shape is otherwise unchanged: the
LocalizedException it used to throw never escaped the method, it was
immediately converted into exactly this array minus the status.

New user-facing strings go through __() and are translated into every
locale the repo carries (nb_NO, nl_NL, sv_SE). The now-unused
"API key is not valid" row is dropped.

Tests cover categorisation of every outcome, the caching protocol
(success TTL, failure TTL, cache hit, per-request memo, key-swap miss,
refresh-writes-forward, corrupt entry), differentiated admin wording for
401/5xx/unreachable, and both gates false-or-absent on every failure
category and present on success. The checkout-config assertions go
through a PHP mirror of the JS gate's own resolution rather than a bare
key check. Each behaviour change was reverted in turn to confirm the new
tests fail without it.

+/**
+ * Cached, categorised outcome of GET /v1/merchant/verify_api_key for the
+ * currently-stored API key.
+ *
+ * Two jobs, both of which used to be done ad-hoc by each caller:
+ *
+ * 1. CATEGORISE. Every non-200 outcome used to be reported identically
+ *    ("API key is not valid"), so an admin whose store simply could not
+ *    reach the API was told their key was wrong and went looking for the
+ *    wrong fix. getStatus() sorts the outcome into buckets an admin can
+ *    act on: OK, INVALID_KEY (401/403 — the key really is wrong),
+ *    SERVICE_ERROR (5xx — the key may be fine, the service is not),
+ *    UNREACHABLE (no HTTP exchange completed at all: DNS, TLS, routing,
+ *    timeout), ERROR (some other non-2xx status), MALFORMED_RESPONSE (a
+ *    2xx that did not carry a merchant id) and NOT_CONFIGURED (no key
+ *    saved yet).
+ *
+ * 2. CACHE. The verification result gates checkout — the payment method's
+ *    availability and the checkout config subtree that the company-search
+ *    control is mounted behind — and both of those are evaluated on every
+ *    cart/checkout render. A live HTTP round-trip per render is not
+ *    acceptable, so results are memoised per request and cached across
+ *    requests, following the same protocol as the sibling providers in
+ *    this namespace ({@see RecordProvider}) and Service\Fx\RateTableProvider.
+ *
+ * Cache protocol:
+ * - Keyed on a hash of the API key itself, so swapping the key (a fixed
+ *   key, or sandbox <-> production) misses the cache immediately and
+ *   re-verifies rather than serving the previous key's verdict.
+ * - A success is cached for CACHE_LIFETIME (5 min). Short enough that a
+ *   key which is revoked upstream stops being honoured within minutes,
+ *   long enough that checkout renders cost nothing.
+ * - A failure is cached for FAILURE_CACHE_LIFETIME (1 min) rather than
+ *   not at all: while the API is unreachable, every checkout render would
+ *   otherwise add its own timing-out HTTP call to the page. Same reasoning
+ *   as RateTableProvider's failure cooldown, with a short TTL so a
+ *   recovery (or a corrected key) is picked up quickly.
+ * - refresh() bypasses the cache for a live check and writes the result
+ *   forward into it. The admin settings page uses that, so a merchant who
+ *   has just corrected a broken key does not have to wait out the TTL for
+ *   checkout to notice.
+ *
+ * The raw response body is deliberately NOT part of the returned status
+ * for any failure category — only the bucket and the HTTP status code.
+ * Verification failures are surfaced to a merchant in the admin UI and an
+ * upstream error body is not something to render there.

Subject: [PATCH 234/885] fix(api-key): include the resolved mode in the
 verification cache key
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Review round 1. The cache key hashed only the API key, while the mode
decides which host the key is verified against — so two store views
sharing a key but configured to different modes shared one cache slot and
could serve each other's verdict. The class docblock claimed a
sandbox <-> production switch missed the cache; now it actually does.

Also corrects an overclaiming comment in Model\Ui\ConfigProvider. It said
the config gate and Two::isAvailable() "can never disagree". The real
basis is narrower and worth stating: ConfigRepository resolves a null
store id through SCOPE_STORE, i.e. the current store, which on a checkout
render is the quote's store — the id isAvailable() passes explicitly. The
comment now says that rather than asserting an absolute.

Subject: [PATCH 235/885] test(api-key): assert the store scope reaches the
 verification call
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Review round 2. The mode now varies the cache key, but nothing asserted
that the store id itself reached Adapter::execute() — so dropping or
hardcoding it would have verified the wrong scope's key while the cache
key still looked correct. Covers both getStatus() and refresh(), at
default scope and at an explicit store view.

Round 2's other finding was that the cache key's mode could diverge from
the mode the Adapter resolves for the request URL. Verified as a
non-issue, no code change: Adapter passes null when the store id is null,
and Repository::getCheckoutApiUrl() then falls back to getMode() — the
same value the cache key derives from. With a store id both sides call
getMode($storeId).

Subject: [PATCH 236/885] fix: reconcile untracked totals-collector amounts
 into a catch-all line item
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

A third-party fee extension that bumps grand_total the same way Magento's
own shipping total does — a totals-collector amount, not a quote/order
item (e.g. Amasty's "Extra Fee" module) — was invisible in the Two API
line_items array while still counted in the reported grand_total, so
sum(line_items) != grand_total.

Adds Order::getOtherChargesLineItem(), a generic reconciliation against
Magento's own aggregate total/tax columns (not any named extension's
fields) that synthesizes a single OTHER-type line for any residual, and
wires it into ComposeOrder, ComposeCapture and ComposeRefund after all
other known line items are built. ComposeShipment is unaffected — its
totals are summed from its own line items by construction, so it cannot
diverge.

Order::getOtherChargesLineItem() no longer guesses a blended tax rate
for an unrecognized residual. It's now a secondary fallback that only
auto-emits a synthetic line when the residual is genuinely untaxed (0%
is always a valid statement); a taxed residual is logged via
LogRepository::addErrorLog and left unreconciled rather than itemized
with an unverified rate.

The primary mechanism is now Api\Fee\FeeLineProviderInterface, a small
adapter contract for itemizing ONE specific known third-party fee (e.g.
a totals-collector amount bumping grand_total without a quote/order
item) with its real tax rate. FeeLineProviderPool aggregates whatever
providers are registered via etc/di.xml — deliberately EMPTY for now:
building a provider for a specific extension needs that extension's
real field/table names verified against an actual install, not guessed
at from documentation. ComposeOrder/ComposeCapture/ComposeRefund call
Order::getFeeLines() before the residual fallback so any future
provider's output is reconciled first.

Known, separate, not fixed here: ComposeCapture's shipping line has no
"first invoice only" guard, unlike ComposeShipment's first-shipment
guard and ComposeRefund's per-document handling. A future fee provider
that needs one-time-only semantics is responsible for its own
idempotency; this call site doesn't provide one.

- * (grand/gross total, tax total) rather than any named extension's
- * fields, so it catches this shape from any current or future
- * extension, not just the one that surfaced the bug report.
+ * The PRIMARY mechanism is a registered FeeLineProviderInterface with

+ * only ever sees what no provider recognized, so it does not know the
+ * residual's real tax rate. It therefore only auto-emits a synthetic
+ * line when the residual is genuinely untaxed (0% is always a valid,
+ * honest statement); a residual with a non-zero tax component is
+ * logged as a warning and left unreconciled rather than guessed at.

  * Covers:
  *  (a) an ordinary order/invoice/creditmemo with no untracked total
  *      produces zero synthetic line items (no false positives from
  *      rounding noise);
- *  (b) an entity with an untracked total (simulated: grand_total
- *      exceeds sum(line_items) by more than known items account for)
- *      produces exactly one correctly-computed synthetic line.

Subject: [PATCH 238/885] fix: close review-found gaps in fee reconciliation
 before merge
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Round-1 adversarial review (Leia/Han/Yoda/Vader) on PR #327 surfaced real
issues, addressed here:

- BLOCKER (Vader): ComposeCapture::getLineItemsInvoice() never itemized
  the surcharge remaining on an invoice (Model\Total\Invoice\Surcharge
  already populates the invoice-level fields for exactly this purpose),
  so the new residual reconciliation would misfire on every capture of a
  surcharge-bearing order — logging every one as an unrecognized taxed
  fee, or worse. Adds the missing surcharge line item, mirroring the
  existing ComposeOrder/ComposeRefund pattern.

- BLOCKER (Yoda): ComposeOrder's own constructor never declared or
  forwarded the new FeeLineProviderPool param to parent::__construct(),
  so DI would never inject a real pool into the order-creation path even
  once a provider is registered. Fixed.

- BLOCKER (Han): the residual epsilon was a flat 1 cent regardless of
  line-item count. Summing N independently-rounded (2dp) line amounts can
  legitimately drift from the entity's own higher-precision aggregate by
  up to ~N*0.005 (the same bound ComposeRefund's own comment already
  documents) with zero third-party extension involved — a flat epsilon
  would false-positive on any large multi-item order. Scaled to
  max(0.01, 0.005 * count($lineItems)).

- BUG (Han): a negative residual (known items exceed grand_total) was
  being auto-reconciled into a negative-amount line, unverified against
  Two's API contract and conceptually wrong — a negative "extra fee"
  more likely signals a bug in our own line-item math than a legitimate
  fee. Now logged and left unreconciled, same as a taxed residual.

- Hardening (Vader): FeeLineProviderPool now isolates each provider (a
  throw doesn't take down checkout/capture/refund for every other order)
  and validates gross_amount/tax_amount are present and numeric before
  trusting a provider-returned line, logging and dropping anything
  malformed instead of silently casting it to 0.

- Cleanup (Leia + Han, convergent): the merge-then-reconcile glue
  duplicated across ComposeOrder/ComposeCapture/ComposeRefund is now one
  shared Order::reconcileOtherCharges() helper. Removed a redundant
  second null-coalescing default (getFeeLines() now trusts the
  constructor's single default instead of re-deriving it).

Adds Test/Unit/Service/Order/ComposeCaptureSurchargeLineTest.php — the
first real test against a Compose* class's actual execute()-adjacent
code path (previous tests only exercised getOtherChargesLineItem()/
getFeeLines() as pure functions), proving the surcharge-line fix closes
the residual gap it was found to open.

Subject: [PATCH 239/885] fix: cap residual epsilon, strengthen provider-line
 validation, add e2e test
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Round-2 adversarial review (Han + Vader, convergent) on PR #327:

- BUG (Han + Vader, convergent): the residual epsilon scaled unbounded
  with line-item count (0.005 * N), so a genuine small untaxed fee on a
  large order (plausible for this plugin's B2B/bulk order shape) could
  vanish with zero log line at all — worse than the logged taxed/negative
  cases, since the "ordinary rounding noise" branch is deliberately
  quiet. Capped at Order::OTHER_CHARGES_EPSILON_CEILING (1.00), bounding
  the worst case regardless of order size.

- BUG (Han): FeeLineProviderPool::isWellFormed() only validated
  gross_amount/tax_amount (the two fields the residual math sums), while
  FeeLineProviderInterface's contract promises a full line shape. A
  provider satisfying the old check while omitting net_amount/tax_rate
  would have sailed through into Order::getTaxSubtotals() and a malformed
  Two API payload. Now requires the full field set (order_item_id, type,
  gross/net/tax_amount, tax_rate).

- Test gap (Vader): reconcileOtherCharges() and its three call sites had
  zero coverage of the actual merge-then-fallback ordering through a real
  execute() call — prior tests only exercised the constituent pure
  functions. Adds
  Test/Unit/Service/Order/ComposeCaptureExecuteReconciliationTest.php,
  driving ComposeCapture::execute() end-to-end for both an ordinary
  capture and one with a genuine untracked/untaxed fee.

Also NIT fixes from Leia's round-2 pass: reconcileOtherCharges() is
protected (was public with no external caller), and a one-line comment
on FeeLineProviderPool's nullable LogRepository param explaining it's
test/hand-instantiation convenience, not an intentional silent-logging
mode.

Subject: [PATCH 240/885] test: rename overclaiming test per round-3 review nit
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

testLineWithNonNumericTaxAmountIsDropped's fixture was also missing
net_amount/type/tax_rate, so the name overclaimed what it isolated.
Cosmetic only — the net_amount/type/tax_rate-missing case is already
covered separately by testLineMissingNetAmountTypeOrTaxRateIsDropped.

Subject: [PATCH 241/885] fix(checkout): source tile search country from the
 address form, scope the order-intent spinner, hide internal company numbers
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

TWO-25326, three items found in live testing.

1. The payment tile's company search ran against the search API's own
   default country whatever the buyer had selected, on one-page checkouts
   only. The tile asked `countryCode()`, whose only live feed for an
   unsaved address is the `countryCode` customer-data section — written
   only by the address-area component, and only once its
   `#shipping-new-address-form select[name="country_id"]` selector
   resolves. A checkout supplying its own address markup matches neither
   that selector nor, before the address is saved, a persisted quote
   address; `fillCountryCode()` early-returns on an empty value, so the
   observable stayed at '' and the search URL carried an empty
   `country=`. The tile now reads the buyer's own country `<select>`
   first (`companySearch.currentAddressFormCountry()`, a priority list of
   address-form selectors ending in a catch-all), keeping the observable
   as the fallback for the saved-address and virtual-cart cases that
   render no address form at all. The address-area picker already read
   that select directly and is unchanged.

2. The order-intent check raised the page-covering `fullScreenLoader`.
   Its spinner is now a `visible:`-bound element inside the payment tile
   and nothing outside the tile is covered or blocked. The module-scope
   reference count is kept as-is — a mid-flight re-render still orphans
   one request and starts another, and the spinner must survive the
   orphan settling first. `afterPlaceOrder()`'s pre-redirect loader is a
   different surface and is untouched.

3. A company number beginning with the literal prefix `TWO:` is an
   internal reference, not a registry number, and is no longer displayed
   anywhere: the dropdown rows, the address-step label, the tile label
   and the order-intent sentence all go through one shared
   `companySearch.formatCompanyNumber()`, whose empty return is what
   removes the label or the brackets rather than blanking them. In the
   notice the brackets go with the number, so it reads "Acme Ltd", never
   "Acme Ltd ()" — which also fixes the pre-existing empty-number case.
   Submitting paths are untouched and still carry the raw value.

Tests cover the country sourcing end to end through the control's
construction, the spinner's locality and refcount, and the display
filter plus each of its call sites. New user-facing string translated
into the existing locale set.

+ * Copyright © Two.inc All rights reserved.

+ *
+ * TWO-25326, Fire Checkout: the payment tile's company search ran against the
+ * search API's own default country (US) whatever the buyer had actually
+ * selected in the address form — on Fire Checkout only, never on Luma or
+ * Amasty.
+ *
+ * Mechanism, and it is a SOURCING gap rather than a hardcoded country
+ * anywhere: the tile's picker asked `countryCode()`, a ko observable with
+ * exactly two feeds —
+ *
+ *   1. the `countryCode` customer-data section, written ONLY by
+ *      address-autocomplete.js, and only once
+ *      `$.async('#shipping-new-address-form select[name="country_id"]')`
+ *      resolves;
+ *   2. updateAddress(), reading the country off the quote's PERSISTED
+ *      billing/shipping address.
+ *
+ * Luma and Amasty render the core `#shipping-new-address-form` markup, so
+ * feed 1 fires on every country change and the observable is current before
+ * the buyer can search. A one-page checkout that supplies its own address
+ * markup matches neither that selector, nor — until the address is saved —
+ * has a persisted quote address to read; `fillCountryCode()` early-returns on
+ * an empty value, so the observable stayed at its `''` default and
+ * buildSearchAjaxOptions() put an EMPTY `country=` on the search URL.
+ *
+ * Fixed by sourcing the tile's search country from the buyer's actual
+ * `<select>` first (companySearch.currentAddressFormCountry(), a priority list
+ * of address-form selectors ending in a catch-all), with the observable kept
+ * as the fallback for the checkouts that genuinely have no address-form select
+ * — a saved address and a virtual cart.

 the buyer's company name **and** company number are known.
 
+A company number is not always DISPLAYABLE, though, even when it is
+known. A value beginning with the literal prefix `TWO:` is an internal
+reference rather than a registry number and is never shown to the buyer
+on any surface. In the notice sentence the renderer then removes the

Subject: [PATCH 242/885] fix(checkout): close adversarial-review findings on
 the TWO-25326 batch
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Round-1 review of the previous commit found four real defects and three
smaller ones.

BLOCKER — the tile's org-number label bound `text: displayCompanyId`
without parentheses. ko unwraps a plain function to the function itself,
so the buyer would have seen the JS source of the method rendered into
the tile whenever a real number was captured. The previous binding was
an observable, which ko unwraps correctly; the switch to a plain
function is what broke it. The template test enshrined the bug by
string-matching the binding instead of evaluating it — it now evaluates
both the `visible:` and the `text:` halves.

MAJOR — the order-intent request kept `global: true`, and Magento's
`loaderAjax` widget is bound on `<body>` listening for jQuery's global
`ajaxSend`/`ajaxComplete`, raising the same page-covering overlay
`fullScreenLoader` does. So the local-spinner change did not actually
achieve a local spinner. Now `global: false`, pinned by a test, since
no behavioural assertion about our own loader can see this.

MAJOR — DOM-first country sourcing was a regression risk on the
platforms that already worked: core renders
`#shipping-new-address-form` inside the HIDDEN new-address modal for a
customer with saved addresses, and renders one billing-address form per
payment method, so an untouched form's store default could beat a
correct quote-derived country. Reversed to observable-FIRST with the DOM
read as the fallback, and the real fix moved to where it belongs — a
delegated `change` watcher on the address-form country select that keeps
`countryCode()` itself current on any checkout. That also closes two
defects the search-only fix left behind on one-page checkouts: the
Business / Sole trader tab never appeared (getSupportedCompanyTypes()
was never reached) and a company captured under the previous country
survived a switch (clearCompanyForCountryChange() never fired).
Per-instance event namespace, detached in dispose(). No initial seed,
deliberately: a seed would read the hidden modal's untouched default and
fillCountryCode() treats a differing value as a change, discarding the
captured company.

MINOR — the selector list dropped `#billing-new-address-form` (one form
per payment method, so `.first()` picks arbitrarily) and
`#co-shipping-form` (an ancestor of the entry above it, so it could only
ever match the same node). Two entries now: core's form, then a
catch-all.

MINOR — the test harness reimplemented the two display helpers verbatim
instead of delegating to the real module, which would have left every
suite that reaches them green against stale logic after a production
change. They now delegate to a lazily-loaded real module.

MINOR — the spinner is gated by `ko if:` rather than `visible:`, so the
`role="status"` node is inserted rather than un-hidden; a region with no
text content that is merely un-hidden announces nothing.

Doc drift fixed in style.css (the label's `visible:` gate gained a
conjunct) and the brand-overlay guide (override copy must keep the
number token inside brackets, since only a bracket pair is stripped).

+         * i.e. only in the window before anything has resolved a country at all,
+         * which is exactly the state that produced the bug.
+         *
+         * That order matters and is not interchangeable. DOM-first was tried and

Subject: [PATCH 243/885] feat(TWO-25326): unify Luma order-intent UI with the
 other plugins
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The order-intent check looked different on every plugin. Luma showed a
wordless spinner while it ran, then stated an approval in brand blue, a
decline in a warm red, and an error only as a checkout toast.

Converged on the shared target: the spokes figure with the sentence
"Checking availability" beside it while the check runs, and all three
outcomes — approved, declined, errored — in one bordered box carrying the
semantic palette (success green, danger red, neutral for an error), with
the intent message alone inside it and no title above it.

Also clears the previous verdict as a new check STARTS rather than when
its answer arrives. The company-change subscriptions did not cover that:
a re-render re-applying the captured company, or a repeat pick of the
company already in the field, writes unchanged values and knockout
notifies nobody — so the previous company's approval sat on screen for
the whole of the next request.

The specs pinning the "cleared at start" rule use an observable with real
knockout's equality semantics, because the AMD harness's double notifies
on every write and would have made that assertion vacuous.

Subject: [PATCH 244/885] fix(TWO-25365): stop sending the merchant storefront
 URL as the buyer company website
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Luma's order-intent request set `buyer.company.website` to
`window.BASE_URL` — the MERCHANT's own storefront URL, not the buying
company's website. Every order intent therefore claimed the merchant's
site as the buyer company's, which is wrong data under a field name
that says something else.

The field is not part of the request Luma is meant to send and nothing
downstream reads it (the Hyva payment component never sent it), so it
is removed rather than re-sourced from somewhere else.

New Test/Js spec composes a real request body with `window.BASE_URL`
deliberately set and asserts on the JSON that would go on the wire, so
it cannot pass on a missing global; a second assertion pins the global
itself as unused so the URL cannot reappear under another key.

Subject: [PATCH 245/885] test(TWO-25365): harden the order-intent website spec
 against three review escapes
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Adversarial review round 1 found the spec passing on mutations it was
meant to catch, and failing on one it should not:

- the source-text guard matched the RAW file, so a comment explaining
  this very fix (which necessarily names the global) turned it red —
  failing on documentation rather than on code. Comments are stripped
  before matching now, same convention as the sibling spec.
- the leak guard was scoped to `buyer`, so the merchant URL relocated
  to a top-level key beside `merchant_id`, read via a computed global,
  passed both tests. It now guards the whole body.
- the `'website' in ...` assertion could never fail independently of
  the exact-shape assertion above it. Removed rather than left reading
  as coverage.

Also drops a header claim about what the API does with the field — not
verifiable from this repo — in favour of pointing at the ticket, and
moves the fixture's product-image host off the storefront host so the
widened guard trips on the defect rather than on a legitimate URL.

Mutation battery: straight revert, computed-key + computed-global, and
the relocated top-level `store_url` all fail the spec; a comment naming
the global keeps it green.

Subject: [PATCH 246/885] test(TWO-25365): close six more escapes the round-1
 hardening left open
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Round 2 mutated the spec's own guards rather than the fix, and got five
passing reintroductions plus one false red:

- the whole-body guard matched the storefront URL EXACTLY. Magento's
  base URL always ends in a slash, so normalising it is the most
  natural thing a reintroduction would do — stripping the trailing
  slash, dropping the scheme, percent-encoding and upper-casing all
  passed. Guarded on the bare host as well, case-insensitively; the
  host token survives every one of those transforms.
- the key regex saw the object-literal form only, so a post-literal
  `…company.website = …` on a country branch the fixture never bills
  to passed both tests — precisely the case the comment claimed to
  cover. Now matches assignment too, and the `web_site` spelling.
- the comment strip was general, which WEAKENS this check instead of
  breaking it: `//` inside a string literal deletes the rest of that
  line, and one `'/*'` string constant opens a fake comment swallowing
  400+ real lines, hiding a plain global read in both cases. Narrowed
  to the two forms this file actually uses — JSDoc blocks and
  whole-line `//`.
- `/BASE_URL/` also reddens on the unrelated local-dev env var names
  that are live vocabulary elsewhere in this module. Narrowed to the
  actual global, with the computed `window[...]` form guarded
  separately (this file has no legitimate computed window access).

Ten-mutation battery, all behaving: the four normalisations, the
post-literal assignment, the `web_site` spelling and both comment-strip
exploits fail the spec; a whole-line comment and a JSDoc block naming
the global keep it green.

Subject: [PATCH 247/885] test(TWO-25365): cover the second route to the
 storefront URL, and stop over-fitting
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Round 3's substantive find: the spec guarded one route to the merchant
URL and there are two. This renderer also injects Magento's URL builder
and calls it elsewhere, and the shared harness double returns its
argument unchanged — so building the storefront root through it yielded
an empty string, invisible to every wire assertion, once under the
removed field's exact name. The builder is now mocked to resolve to the
real storefront root, as the browser does, and the existing body guard
covers both routes with no new assertion.

Three narrowing mistakes from the previous round, each proven by a
passing mutation:

- matching `window.BASE_URL` rather than the bare token let
  `const { BASE_URL } = window` through. Back to the token: the
  justification for narrowing was wrong anyway, since this file contains
  no other name of that shape — the local-dev env vars live in shell and
  PHP config, which this check never reads.
- `\b` before `web` fails after an underscore, so `company_website:` and
  `merchant_website:` escaped — the likeliest names if the field moves
  out of the company object. Anchor dropped.
- the fixture's product-image host needed the reason it is off-storefront
  written down, since production images really are storefront-hosted and
  a maintainer "fixing" the fixture would red the guard with no defect.

Also trimmed the rationale prose, which had grown longer than the
apparatus it explains, and renamed the second test — it stopped being
about one global two rounds ago.

Ten-mutation battery: both builder-route shapes, the destructured global
on an unexercised branch, the two underscore-prefixed key names, the
straight revert, the computed-and-normalised relocation and the
post-literal assignment all fail. A comment naming the global, and a
legitimate new URL-builder call, both stay green.

Two rounds of comment-stripping still left the false-red channel open:
only whole-line and JSDoc comments were stripped, so appending
`// no BASE_URL here` to a line of CODE — the most natural way to
document this fix at the call site — reddened the check. That is the
exact failure mode the strip exists to prevent. Trailing comments are
stripped now, with a quote exclusion so the pattern declines to strip
rather than risk eating a URL inside a string.

The `window[...]` guard is removed. It outlawed a general JS construct
across the whole file to cover one narrow case — a computed global read,
on a branch no fixture exercises, under a key name no regex anticipates
— and that case is strictly narrower than others this spec already
accepts as out of reach. Banning the construct bought less than it cost
the next person to touch the file.

Also corrected the justification for the bare-token match: the claim
that env-var names of that shape were the false-positive risk was wrong.
A leading word boundary cannot match `TWO_API_BASE_URL` at all, since
the boundary fails after an underscore — the same property the key regex
below exploits deliberately. And the residual gaps are now written down
rather than implied, so the guards are not read as more than they are.

Eight-mutation battery: trailing and whole-line comments naming the
global stay green; the straight revert, the underscore key, the builder
route, the destructured global, `window.location.origin`, and a global
read on a line whose string contains `//` all fail.

Subject: [PATCH 249/885] test(TWO-25365): exclude backticks from the
 trailing-comment strip too
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The exclusion class covered ' and " but not `, and this file composes
URLs in template literals. A template literal containing whitespace-//
on a line that also read the global would therefore have had its real
code deleted — silently weakening the token check, which is the exact
failure mode the exclusion exists to prevent. Latent rather than live:
no such line exists today.

Verified in node rather than reasoned: with the backtick in the class,
`a // ${window.BASE_URL}` survives the strip and the token check still
sees it; a genuine trailing comment is still removed.

Subject: [PATCH 250/885] refactor(TWO-25326): sentence-case admin captions,
 retitle the search pair
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Every admin caption in the module is now sentence case, matching the
convention the other three plugins use — field, group and section labels
in both etc/adminhtml/system.xml and the brand form template they are
synthesised from, kept in step as that file's own note requires. The
minimum-order Block label override and the two backend validation
messages that quote the caption follow it.

Two captions change wording rather than casing, aligning Magento with
WooCommerce verbatim:

  Enable Company Search -> Enable company search in address entry
  Enable Address Search -> Autofill company address

The company-search help text is WooCommerce's wording too. Its previous
text had drifted into describing the mechanism (and quoting a ticket
section number at the merchant), which is not what a merchant reading
the setting needs.

The address-autofill help text loses its "this setting alone controls
address lookup, on both the shipping and the payment method step"
claim, which the following commit makes untrue.

Every renamed English string is a key in the three i18n catalogues, so
each is re-keyed there; casing-only renames keep their existing
translation, and the four genuinely new English strings get real nb_NO,
nl_NL and sv_SE translations rather than a copy of the source.

Dropdown option labels are deliberately untouched — they are values
rather than captions, and re-casing them is a separate question.

Subject: [PATCH 251/885] fix(TWO-25326): never autofill the address from the
 tile's own company picker
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The payment-tile company picker autofilled the address on every pick,
gated only on "Autofill company address". With "Enable company search in
address entry" OFF the tile is the control's home, which means the buyer
has already completed and confirmed the address step before they can
pick a company — so the pick silently overwrote city, postcode and
street with the registry's values, behind their back and after the fact.

Autofill is only ever a PRE-fill of a form the buyer is about to work
in, so it now requires both settings: the shared
`isAddressSearchEnabled` gate inside lookupCompanyAddress(), plus a
positional gate in the renderer's addressLookup().

The saved-address and virtual-cart fallback keeps working. Those keep
the tile as the only search location while the setting stays ON, so the
new gate passes and the tile's own billing form is still filled — which
is what TWO-25193 added the tile lookup for.

The gate deliberately does NOT move into the server-side
isAddressSearchEnabled flag. That flag reads one setting and is shared
with the address-area picker (TWO-25202); the condition being added is
about WHICH picker is asking, which only the caller knows. The
now-stale "this setting alone controls address lookup on both steps"
notes in the Config repository, its interface and the shared JS model
are corrected to say so.

Tests: the existing payment-step "both flags on" case now states the
address-area setting explicitly (it was relying on undefined); two new
cases pin the OFF case with address search left ON — so a fix that only
re-read the address-search flag fails — and pin that the shared model
carries no company-search gate of its own, guarding against the
conjunction being pushed down where it would break the address-area
picker too.

Review findings, highest first.

The caption re-key overwrote three existing translations instead of only
moving the key. "Minimum order value, %1" had its nb_NO, nl_NL and sv_SE
bodies replaced with a different term from the one every sibling row in
the same file uses, so the field label and its own validation messages
would have read as two different things on one screen. Bodies restored;
only the key moves, which is all a re-case should ever do.

The brand form template's two search fields carried `translate="label"`,
so the comments this PR rewords would have rendered English-only in every
brand overlay despite the catalogue rows existing. Both now say
`translate="label comment"`, matching system.xml. The other twelve fields
in that file have the same gap; left alone as pre-existing and wider than
this PR.

One missed admin caption: the creditmemo override label "Refund Two
Surcharge". Re-cased, with "Two" kept as the brand name it is.

addressLookup()'s doc comment justified the gate with "the buyer has
already completed the address step", which is a DOM condition, while the
gate reads a setting. Those disagree for a virtual cart with company
search in address entry OFF, where the billing form is genuinely blank
and autofill is now dead — a real cost of the rule as TWO-25326 states
it, so the comment now says that plainly instead of implying the gate
proves it. It also no longer offers isTileCompanySearchActive() as if
that predicate identified the gated case; it is true in both tile cases.

Stale notes corrected in address-autocomplete.js (still described the
shared gate as the whole rule for both pickers) and in the TWO-25202
migration patch's header (its config semantics do hold; say which part
TWO-25326 changed and which it did not).

The three fixtures that build a renderer context without the new flag now
state it explicitly as false, with the reason: they count $.ajax traffic,
so letting the detail lookup fire breaks them, and leaving the flag
undefined would silently vacuum any autofill assertion added later.
Dropped the new "shared model carries no gate" test — it duplicated an
existing case with a weaker assertion.

Tests: 30 suites, 386 pass.

Subject: [PATCH 253/885] =?UTF-8?q?fix(TWO-25326):=20review=20round=202=20?=
 =?UTF-8?q?=E2=80=94=20caption=20cross-references=20and=20dead=20fixtures?=
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The surcharge guard's save-blocking message still named the old captions
and told the merchant to "see the Surcharge Method field" — the whole
point of that message is the cross-reference, and it pointed at a caption
that no longer exists. Re-cased, along with the three PHPUnit assertions
that pin its text and the eleven doc comments elsewhere that quote a
caption this PR moved (README-style guide, brand registry interface,
source models, backends, two unit-test headers). The round-1 sweep had
done two of these and left the rest, which is the inconsistency the
sweep existed to remove.

"All Allowed Countries" is deliberately NOT re-cased: no source in this
module emits it, so it is a Magento core string and the catalogue key has
to keep core's casing to resolve at all.

Round 1's six explicit `isAddressAreaCompanySearchEnabled: false` fixture
fields are removed. They were dead — no fixture in those three files
reaches `select2:select`, so `addressLookup()` is never called and the
comment's claim about unrelated $.ajax traffic was wrong. (Setting them
TRUE does break those suites, but via `isTileCompanySearchActive()`
suppressing the bind, not via autofill — so the fields were mis-diagnosed
either way.) Three of the six also sat on contexts that load
address-autocomplete.js, whose addressLookup() reads no such flag, so the
comment pointed a future author at a gate that is not there.

Also: the dropped test's `companySearch:` return key was left orphaned;
`RepositoryAddressSearchTest`'s header still said address lookup is
"gated by enable_address_search alone", which is the one file a reader
greps for the gate rule; and the tile's inline note claimed both gates
live inside addressLookup() when the shared one is a level down in
company-search.js.

Tests: 30 suites, 386 pass.

Subject: [PATCH 254/885] feat(TWO-25386): port 8 admin controls from
 woocommerce/prestashop plugins
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Ports the admin controls flagged in TWO-25386 as present on only one or
two of the four plugins, onto Magento:

woocommerce-plugin origin:
- Vendor/site name (multi-site) — sent as vendor_name on order creation
- "What is Two" checkout explainer link
- Display input tooltips on optional checkout fields
- Skip confirm-order nonce check (admin-surface parity only — Magento's
  confirmation callback has no nonce layer to skip; see the docblock on
  Controller\Payment\Confirm)
- Clear settings on module uninstall (Magento's nearest equivalent to
  "on deactivation" is module:uninstall; new Setup\Uninstall)

prestashop-plugin origin:
- Payment-method subtitle, store-view scoped, overriding the brand
  default subtitle when set
- Disable SSL verification debug toggle — also fixes Service\Api\Adapter,
  which previously disabled TLS verification unconditionally regardless
  of any config
- Install health checklist admin panel (API key / environment / SSL
  verification), mirroring prestashop-plugin's three checks exactly

New fields are mirrored into both etc/adminhtml/system.xml and
etc/adminhtml/brand_form_template.xml, matching the existing brand-form
synthesis convention.

Subject: [PATCH 255/885] fix(TWO-25386): address round-1 adversarial review
 findings
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

- Setup\Uninstall: derive the config-path prefix from the active
  brand's own code (BrandRegistryInterface::getCode()) instead of
  hardcoding two_payment, drop the dead two_search/* clause (those
  fields already live under payment/<code>/* like everything else),
  escape LIKE special characters in the code, and read the toggle at
  an explicit default scope
- Service\Api\Adapter: thread $storeId through the new SSL-verify
  check, matching the other store-scoped calls in the same method
- brand_form_template.xml: add the missing "comment" to translate=
  on 7 mirrored fields so their help text is translatable, and move
  subtitle to sit immediately after title (matching system.xml's own
  document order for that field)
- Drop a stray woocommerce-plugin internal identifier from two
  comments
- Soften the ABOUT_URL docblock's override claim — a brand overlay
  has no subclassing point to override a PHP constant from

From c9af07f39ad173f974c41bc132c9e0b810e0f6e6 Mon Sep 17 00:00:00 2001

Subject: [PATCH 256/885] feat(TWO-25386): regroup admin Configuration into
 unified 6-section scheme
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Reorganize etc/adminhtml/system.xml (and the mirrored
brand_form_template.xml) into the A-F section scheme agreed for
cross-plugin parity: General, Checkout Fields, Company Lookup,
Payment Terms, Order Management, Diagnostics — same names/order as
prestashop-plugin and woocommerce-plugin.

Pure reorganization: no field config_path or behaviour changes, only
which section/group each field renders under and the section/group
labels. `two_general`, `two_search` and `two_payment` keep their
historical section ids (relabeled General/Company Lookup/Payment
Terms) to minimise breakage of Plugin\Config\Structure\HidePaymentSection
and brand-overlay `suppressed_fields` paths; `two_checkout_fields` and
`two_order_management` are new section ids for content split out of
the old `two_payment` section (title/subtitle/sort order/country
availability/minimum order/order intent, and fulfilment
trigger/status/tax subtotals respectively). The load-bearing
invoice-email/PO/project/department/order-note order (TWO-25263) is
preserved unchanged inside the existing `checkout_fields` group.

Updates HidePaymentSection's TARGET_SECTIONS and its test, the
CheckoutFieldDefaultsTest section-id xpath, and brand.xsd/
brand-overlay-guide.md docs describing the section-suffix contract.

Subject: [PATCH 257/885] fix(TWO-25386): drop <depends> on "active" that the
 section split made inert
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Magento renders each top-level <section> as its own admin page, so a
<depends> can only resolve within the section it's declared in.
Splitting "active" (Enable payment method) into two_general while
title/subtitle/merchant_minimum_order(_basis) moved to
two_checkout_fields left their <depends><field id="active">1</field>
</depends> unable to ever fire — those fields would always render
regardless of whether the payment method is enabled, a real behavior
regression the adversarial review round caught (Yoda/Vader,
independently).

Also drops the same dead <depends> from enable_company_search/
enable_address_search (two_search), which was already cross-section
before this PR (two_search vs two_payment) and therefore already
inert — pre-existing, fixed here since the PR already touches the
same contract.

Also fixes a stale docblock in SynthesiseBrandAdminForm.php still
describing "the four canonical sections" (missed when the other
section-id references were updated in the previous commit).

From fa399c535ef357f103f74865be63529c38d6bef2 Mon Sep 17 00:00:00 2001
From: Douglas Lindsay <dlindsay@two.inc>

Subject: [PATCH 258/885] fix(TWO-25386): correct vendor name caption/help
 text, move SSL verification to Diagnostics
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

- vendor_site_name field: caption now "Vendor name (optional)"; comment
  now accurately describes actual behavior — sent as vendor_name on
  every order-create (POST /v1/order) and order-edit (PUT /v1/order/{id})
  request via ComposeOrder::execute(), confirmed against Service/Order/ComposeOrder.php
  and Observer/SalesOrderAddressUpdate.php.
- disable_ssl_verify: moved from General/general group to
  Diagnostics/admin_controls group, where it belongs as a support-only
  escape hatch, not a general checkout setting. sortOrder=30 chosen to
  avoid colliding with existing admin_controls fields (10, 20).
- Mirrored both changes in brand_form_template.xml, which duplicates
  system.xml's structure for brand overlays.

Subject: [PATCH 259/885] feat(TWO-25386): wire {{provider}} brand-token
 substitution for admin captions
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

brand_form_template.xml's `{{provider}}` token was declared and threaded
through SynthesiseBrandAdminForm::renderBrandTemplate() but never used in
the template body, so a handful of admin <comment>/<label> strings hardcoded
"Two" for every brand, including any partner brand overlay synthesised from
this template. Converted the vendor_site_name comment, the "What is Two"
link label/comment, and the disable_ssl_verify comment to interpolate
{{provider}}.

etc/adminhtml/system.xml is deliberately left untouched: it is the base
Two brand's own static declaration (never token-substituted — Magento
merges it directly), so its literal "Two" text is correct as-is. Verified
field/group/section ids and sortOrders still match between the two files.

Also converted two admin/order-facing PHP strings that hardcoded "Two"
outside the XML template, found via a repo-wide sweep:
- Block/Adminhtml/Creditmemo/SurchargeOverride::getLabel()'s no-description
  fallback ("Refund Two surcharge")
- Block/Sales/Total/Surcharge::initTotals()'s no-description fallback
  ("Two Surcharge"), shared by order/invoice/creditmemo totals on both
  admin and storefront

Both now resolve via BrandRegistryInterface::getProductName(), matching
the existing pattern in ApiKeyCheck.php.

Added ConfigStructureSynthesisFixtures.php test stubs (real method
signatures for Converter/Dir/LoggerInterface) since this repo's PHPUnit
harness has no vendor/ install and the catch-all Magento stub is
method-less; needed so SynthesiseBrandAdminFormProviderTokenTest can mock
specific methods.

Subject: [PATCH 260/885] fix(TWO-25386): fix CDATA entity-escaping bug in
 {{provider}} substitution; guard classmap collision
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Adversarial review round 1 found two real issues in the {{provider}}
token substitution added in the previous commit:

1. The disable_ssl_verify comment is a CDATA section; CDATA content is
   never entity-decoded by the XML parser. Substituting the
   entity-escaped {{provider}} value there would bake literal "&amp;"
   etc. into that caption for any provider name containing "&", "<",
   ">", "'" or '"' — not hypothetical, since legal/partner entity names
   routinely contain "&". Added a distinct {{provider_cdata}} token,
   substituted RAW (no escaping), used only at that one CDATA site.
   Added a regression test with a provider name containing "&".

2. Test/Stubs/ConfigStructureSynthesisFixtures.php declares real-named
   stub classes including Psr\Log\LoggerInterface, guarded only by
   class_exists(..., false) — which prevents redeclaration, not
   classmap indexing. composer.json's psr-4 autoload maps the module
   root with no exclude-from-classmap, so an optimized/authoritative
   composer classmap build (composer dump-autoload -o/-a, standard in
   Magento prod deploys) would index Test/ alongside production code,
   risking a collision on a framework-foundational interface loaded on
   every request. Added "exclude-from-classmap": ["/Test/"] to
   composer.json, closing this for all Test/Stubs files, not just the
   new one.

Subject: [PATCH 261/885] fix(order): omit blank optional fields from the
 create-order payload

TWO-25386. Several optional fields in the create-order payload are
length-constrained when present, so composing them as empty strings makes
the API reject the order with a schema error rather than ignoring them.
vendor_name was the live case: its admin setting defaults to blank (and
the help text tells merchants to leave it blank when they run a single
site), so every order failed until a merchant typed a value.

Omit the key instead of sending an empty string for vendor_name,
buyer_department, buyer_project, buyer_purchase_order_number, order_note,
merchant_urls.merchant_edit_order_url, and the two invoice payment
reference fields. Done via an explicit allowlist, not a blanket
empty-strip over the payload, which would also drop
merchant_urls.merchant_confirmation_url and the amount fields - those are
required and must survive regardless of value. The blank check is a
string comparison rather than empty(), so a literal "0" department or
project reference is still sent.

merchant_edit_order_url and the payment reference fields were hardcoded
empty, so they are simply dropped - the plugin has no merchant-side
edit-order route and no value for the references. They are omitted rather
than nulled, since null is rejected where empty string is not.

Also corrects the preceding comment, which claimed woocommerce-plugin
sends vendor_name unconditionally. It does the opposite: it only adds the
field when it has a value. Left as written, the comment would talk the
next reader out of this fix.

Adds caller-level coverage: the config getter is entitled to return an
empty string (its own test asserts that, and stays), so the assertion
that belonged here is that the caller leaves the key out. Test/Stubs
gains a URL builder with a real getUrl() so the merchant_urls
construction is exercisable outside the full framework.

From d4c152c928a954bfe8ecb09d42b304ae6506f77b Mon Sep 17 00:00:00 2001
From: Douglas Lindsay <dlindsay@two.inc>
Date: Wed, 12 Aug 2026 17:01:02 +0100
Subject: [PATCH 262/885] fix(order): guard optional field reads on the admin
 order-edit path
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The admin address-edit observer re-composes the order payload from the
stored payment additional_information, reading the Department and Project
values without a null-coalesce. Both are optional at checkout, and since
blank optional fields are now omitted rather than sent as an empty string,
those keys are simply absent for any buyer who skipped them.

Unguarded, that raised a PHP warning. Developer mode promotes it to an
exception, the observer catch swallowed it into order status history, and
the order-edit request was never sent — so the address edit never reached
us and a raw warning string showed up in admin-visible order history.

Coalesce both reads to an empty string; the composer applies the same omit
rule again, so the outgoing payload still leaves the keys out.

Adds the first coverage over the observer to composer re-composition path,
which is why this was not caught: a stored payload missing both keys must
not warn, must record acceptance rather than a swallowed warning, and must
still attempt the order-edit request.

Ref: TWO-25386

Subject: [PATCH 263/885] INF-1458/ci: point Auto-PR at staging (develop branch
 removed)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

`develop` was renamed to `staging`; INF-1458 moved merge-back over but
missed `auto-pr.yml`, so the workflow still triggered on `push:` to a
branch that no longer exists. Nothing has opened the promotion PR since,
and ~361 commits of staging work are unpromoted.

The trigger mechanism was already correct — `push:` to a branch fires on
merge into that branch — so this is a branch-name fix only, not a switch
away from a `pull_request` trigger.

- auto-pr.yml: retarget the trigger, job id, check name, `gh pr list`
  filters, the `compare/main...` API call, and the PR title/body to
  `staging`. Fix the body's reference to a workflow filename that was
  renamed away two commits later.
- auto-pr.yml: add a `concurrency` group. The "is a PR already open?"
  test is check-then-create, so two merges landing on `staging` in quick
  succession could both pass it and the second `gh pr create` would fail
  with a red check.
- claude-code-review.yaml: the long-lived-sync-PR skip keyed on a head
  ref of `develop`. Without this the cumulative promotion PR trips the
  reviewer's 20000-line `gh pr diff` ceiling and hard-fails every sync.
- ci.yml: drop `develop` from the push/pull_request branch lists.
- README.md: document auto-pr.yml alongside merge-back.yml.

Left alone deliberately: the second long-lived branch already listed in
the review skip list (a separate overlay branch, out of scope for this
rename), the `dev-develop` composer branch alias, and every unrelated
use of "developer" (Magento developer mode, prose).

Subject: [PATCH 264/885] fix(order): stop the admin address edit blanking
 stored order fields
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The order-edit request sent when an admin changes an order address is a
merging update of the order already held by the payment provider. A field
left out of that request keeps whatever value is stored against the order;
a field sent as an empty string is accepted and overwrites the stored
value with blank. Neither case is rejected, so nothing surfaced.

The observer appended three fields unconditionally, always empty, after
the composer had already applied its omit rule — a merchant reference, a
free-text additional-info field, and a delivery/tracking object. Every
admin address edit therefore erased all three.

The delivery object is the most damaging of the three, because it is not
merged field by field: supplying it replaces the stored delivery record
wholesale, so the fields this payload never sets — tracking URL, expected
delivery date, delivery method, and the recipient details — were cleared
as a side effect of an unrelated address change.

All three are now omitted unless there is a value to send, using the same
explicit-allowlist shape as the composer rather than a blanket empty-strip,
so the required fields survive untouched. The buyer shipping address is a
separate required field and is unaffected.

In practice the plugin has no source for any of the three today, so this
is a latent defect rather than observed loss: the only builder for the
delivery object is an uncalled private method, and nothing populates the
reference fields. It still destroys values set through any other channel.

Subject: [PATCH 265/885] fix(order): correct the omit-field rationale and drop
 the unreachable branch

Round 2 review on TWO-25386 found that the reasoning committed alongside the
fix was itself wrong in three places, plus one branch that can never run.

The order-edit observer no longer touches merchant_reference,
merchant_additional_info or shipping_details at all. Nothing in this plugin
ever writes those keys into the payment additional_information, so the
sourcing added for them read values that never exist: every write there
either copies the create-order payload (which does not carry them) or sets
the completion marker, and the checkout data-assign path is limited to its
own fixed key list. The previous guard also sent a reconstructed
shipping_details whenever either of its two fields was non-empty, which is
destructive in every branch, since that object is replaced wholesale rather
than merged. All three keys are now omitted unconditionally, with the reason
recorded in place. The three tests that exercised the populated branches go
with it; the tests asserting absence stay.

Two comments in the composer stated the wrong reason for omitting a field.
Only vendor_name has to be non-empty when the key is present -- that is the
rejection this ticket was raised for. merchant_edit_order_url,
buyer_department, buyer_project, buyer_purchase_order_number, order_note and
the invoice payment-reference fields all accept an empty string on create, so
they were never causing rejections. Omitting them is still right, for a
different and equally real reason: the order-edit call merges scalars, so an
absent key preserves the stored value while an empty one overwrites it, and
composing them blank was erasing buyer-entered data on admin address edits.
The comments now distinguish the two cases. No behaviour change here.

The optional-field loop now skips non-scalars. The observer that stores
checkout data validates only that the top level is an array, so a crafted
request could leave an array in one of these values, and casting that to
string raises a warning that developer mode turns into a failed order
placement.

Adds a payload-wide test that walks the composed create payload recursively
and fails on any empty string outside an explicit sanctioned list, currently
empty. That generalises past the per-field assertions: it catches any future
field added as an empty string without needing an update when the payload
grows -- only when a field is legitimately allowed to be blank.

Test suite: 713 tests, 1330 assertions, green (three deleted, two added).

Subject: [PATCH 266/885] chore(INF-1458): drop a stale head_ref exemption from
 the review workflow

The code-review job carried a second `github.head_ref !=` guard naming a
branch that has never existed on this remote (confirmed against both
`git branch -r` and the refs API, which returns 404 for it). The guard
could therefore never evaluate false, so removing it changes no
behaviour on any PR this repo can actually receive.

The `staging` exemption stays: it is load-bearing. Bot-opened
staging -> main sync PRs accumulate the whole cumulative diff and blow
past the reviewer prefetch step's 20000-line ceiling, so those PRs must
keep skipping review; topic PRs into `staging` are where review happens.

Validated with a strict YAML parse of the workflow and by re-checking the
job's `if:` expression: parentheses balance, and the only remaining
head_ref guard is the `staging` one.

Subject: [PATCH 267/885] chore(INF-1458): drop the dead dev-develop composer
 branch alias

`extra.branch-alias` mapped `dev-develop` to `2.0.x-dev`. A branch alias
only ever applies to a `dev-<branch>` requirement, and that branch no
longer exists on this remote, so the entry can never be resolved against
anything.

Verified before removing:
- no `develop` branch on `origin` (`git branch -r`);
- nothing in the repo, CI or scripts requires or references
  `dev-develop`. The only other `dev-main` hits are version-string
  fixtures in Test/Unit/Model/ProvenanceTest.php, unrelated to the alias
  map.

`dev-main` stays, so `branch-alias` is still a non-empty object and no
empty key is left behind. Consumers on a tagged release are unaffected:
aliases influence only the resolution of dev constraints, never tags.

No replacement `dev-staging` alias is added - deletion only.

Subject: [PATCH 268/885] fix(order): correct the omit-field comments and cast
 optional values

Round 3 review. The comments in this diff kept asserting facts about the
order API that this repo cannot falsify, so they kept rotting. They now
state only local, repo-checkable facts plus the decision taken here, and
point at TWO-25386 for the field constraints and edit-merge semantics.

Comment corrections:

- The order-edit blanking affected buyer_purchase_order_number and
  order_note, not all four optional buyer fields. buyer_department and
  buyer_project were forwarded from the stored additional_information and
  survived.
- The payment reference fields are omitted because the plugin has no value
  to put in them and they default when absent. The plugin never sends
  invoice_details on the edit path at all, so the previous "would blank on
  a later edit" claim was wrong.
- Dropped the merchant_edit_order_url claim about merge behaviour: that
  field is nested, and nested-object merging was never verified. The
  verified ground - no merchant-side edit-order route, so no URL to put
  there - stands on its own.
- Dropped the unverified "accepted and overwrites" mechanism for
  merchant_reference and merchant_additional_info. Nothing in this plugin
  ever writes those keys, which is sufficient on its own.
- shipping_details was sent blank on every admin address edit, described
  correctly at first mention instead of corrected two lines later.
- Softened the claim that shipping_address is required on the edit schema.
  The load-bearing point is that it is a different field from
  shipping_details.
- "allowlist" was doing two jobs. The composer has an omit-when-blank
  list; only the test constant is an allowlist.
- The empty-string check is a local policy statement ("sanctioned here"),
  not a claim about what the API permits.
- Noted that companyName and companyId are inert under the composer test
  fixture, which stubs getBuyer() and getAddress() to [].

Code and test changes:

- Cast optional field values to string on assignment. is_scalar() stopped
  arrays, but true and 123 passed through uncast and put a boolean or a
  number in the JSON where a string belongs. This also normalises a
  pre-existing behaviour on staging, not just the new omit path.
- Seeded the accepted-empty-string allowlist with the three line-item
  paths that are legitimately blank on synthesised shipping, fee and
  surcharge lines, each with its reason. The fixture stubs line-item
  composition out and leaves the surcharge at 0, so the previously empty
  constant was a fixture artifact; enriching the fixture later would have
  produced a failure reading as a regression in this ticket.
- Recorded that allowlist entries are keys, and pinned the shape by using
  key-style entries, so a list-style entry cannot silently no-op.
- Asserted the order stub's save count instead of leaving it collected and
  unchecked.
- Renamed the payload sweep to name its real scope: the keys the composer
  assembles itself, not the stubbed nested structures.

No change to the omit mechanism, the null-coalescing guards,
shipping_address, merchant_confirmation_url, or the company name fallback
in Service/Order.php (TWO-25427).

Subject: [PATCH 269/885] docs(TWO-25386): drop port-provenance comments
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The TWO-25386 admin-controls work left "ported from <other repo>"
provenance notes scattered across the docblocks, XML comments and test
headers it touched. They record where a control came from, which is
history the ticket already holds and not something a reader of this
module needs.

Comments and docblocks only — no code, behaviour, config default, admin
label or user-visible string changes. Where provenance was one clause of
a sentence that also explained something useful, only the clause is
gone and the explanation is kept (re-wrapped where the trim left a
ragged line).

Deliberately left in place: comments that state a live cross-platform
behavioural contract rather than provenance — the load-bearing canonical
checkout-field order, the shared 300ms search debounce, the semantic
order-intent palette, the surcharge tax-treatment rule, and the design
notes explaining why this module's company-search wiring diverges from
its counterparts. Those describe behaviour a merchant or buyer relies on
today, not where code came from.

Subject: [PATCH 270/885] docs(TWO-25386): drop remaining cross-platform
 references from comments

Removes the sibling-platform references held back for review, keeping the
explanations they were embedded in rather than leaving husks behind:

- Model/Provenance.php: the resolution-order docblock enumerated the full
  set of plugin artifacts sharing that order. Dropped the enumeration; the
  freshness-ranked rationale it introduced is unchanged.
- Service/Order.php: the negative-discount guard recorded which platform
  the phantom-negative rounding trap was first observed on. Dropped that
  clause, kept the TWO-24741 ticket reference and the rounding rationale.
- docs/brand-overlay-guide.md: the order-intent notice section compared
  markup class names and enablement-key semantics across platforms.
  Restructured to state this plugin's own behaviour, since removing the
  comparisons left both paragraphs reading as fragments.
- .github/scripts/decide-bump-level.sh and its test: comment-only
  rewording to describe the filename-discovered upgrade-script mechanism
  by behaviour instead of by platform. No logic, no strings, no
  assertions touched.

Comment-only change: 713 PHPUnit tests and the 26 bump-script cases pass
unchanged, codesniffer clean at --severity=6.

 ### A warning about validation
 

From 7f90616b11d00b2e3f61de183ad7227b2bcdcb63 Mon Sep 17 00:00:00 2001

Subject: [PATCH 271/885] fix(soletrader): trust the authenticated email after
 popup signup (TWO-25461)

The `ACCEPTED` postMessage from the sole-trader signup popup fires after
the buyer has authenticated server-side, but the handler re-ran the
PASSIVE pre-auth check: it only autofilled when the returned buyer's
email equalled the checkout form's contact email. On a mismatch no
branch ran at all, so the buyer completed verification and was left
with a blank readonly, required company field and no route forward.

Threads an explicit `authenticated` flag through a shared
`resolveBuyer()`: the passive prefetch keeps the email-match
requirement (nothing proves the cookie's buyer is the person checking
out), the post-authentication path skips it entirely and fills from
whatever identity authenticated.

Subject: [PATCH 272/885] fix(checkout): repair three defects in the
 sole-trader popup launch (TWO-25461)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Three unrelated-looking bugs on one code path — the sole-trader signup
popup launch — closed together.

1. The popup opened 610px wide, under the 700px the hosted signup flow's
   own layout needs, so the flow was clipped. Height 805 was already
   correct.

2. The note's overlay element bound a click to `hideIframe()`, which
   exists on no view model. It was the last remnant of a removed in-page
   iframe modal: no `.iframe-parent` markup survives and nothing adds
   the `.show` class its stylesheet needs, so the element was
   permanently invisible and the broken binding only latent — a
   stylesheet making it visible was all it took to turn a click into a
   TypeError. Removing the dead element is the smaller fix than
   inventing a method for it.

3. The fallback link was offered before the signup tokens were minted,
   so clicking it built `?businessToken=&autofillToken=` — a URL the
   hosted flow rejects. `openIframe()` now refuses to open without both
   tokens, and both fallback branches only offer the link once they
   exist. `prefetchSoleTrader()` returns a promise on every path so the
   not-ready branch can sequence on the mint.

Tests: Test/Js/gateway-method-sole-trader-popup.test.js pins the 700
width (behaviourally and by source scan), asserts every method the
template arrow-binds to a click exists on the renderer — the
`hideIframe()` class of defect, which only throws when clicked and so
survives every non-clicking test — and covers the token-gated link in
both fallback branches.

Subject: [PATCH 273/885] feat(soletrader): write the buyer's registered
 address on adoption (TWO-25461)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

§1(a.3): the payment tile resolved its country through three
shipping-biased feeds — a customer-data section written from the
shipping form, whichever quote address fired last, and a DOM fallback
that tries the shipping form first. The tile has no address fields of
its own, so its country is the BILLING/invoice-role address's.
searchCountryCode() now reads quote.billingAddress() first — the same
source the autofill payload, getData() and placeOrderIntent() already
use — and keeps the existing feeds as fallbacks.

§5: fetchBuyer() has always returned the buyer's address beside their
organisation number and company name, and all three call sites read the
two identity fields and discarded the address, so a buyer who had just
enrolled retyped an address the plugin was holding. The three sites now
share one adoptSoleTraderBuyer(), which writes the address and then the
identity. Deliberately NOT gated on either address-lookup switch: both
are legitimately off wherever company search is not mounted in the
address area, which is exactly where the sole-trader entry point lives.

applyAddress() gains the field routing the write-back needs, shared with
an ordinary company-search selection rather than special-cased:
building/apartment take line 1 and move the street to line 2, a street
alone takes line 1 and leaves line 2 untouched, no de-duplication
between the lines, and a region goes to the region select (matched on
option name or code), else a visible free-text region field, else onto
the city with a comma. Line 2 and the region join the revert's field
list so a country switch can still take back everything the write
reaches. The country is never written.

+ *
+ * TWO-25461 §2.6: where each part of an external address payload lands in the
+ * checkout address form.
+ *
+ * `applyAddress()` used to write three fields — city, postcode and the FIRST
+ * street line, taking the street line from `street_address` alone. Two payload
+ * shapes reach it: a registered-company detail response, and (since the
+ * sole-trader write-back) an autofill buyer record, which spells the street
+ * `street` and can carry a `building`/`apartment` and a `region` beside it.
+ * Everything but the street was silently discarded.
+ *
+ * The rules, and the reasoning is in the guide rather than invented here:
+ *
+ *  - a building/apartment is the more specific locator and takes LINE 1, with
+ *    the street moving to line 2; with neither, the street takes line 1 and
+ *    line 2 is left ALONE rather than blanked;
+ *  - no de-duplication between the lines even when identical — real addresses
+ *    repeat, and suppressing the second line discards registry data;
+ *  - a region goes to the region control when the form has a usable one
+ *    (best-effort text match, inherently lossy), and otherwise onto the city
+ *    with a comma, which is lossy but visible and correctable.
+ *
+ * The DOM here is REAL jsdom markup, not a recorder: the field routing is
+ * expressed as selectors and as an option-label match, so a double that
+ * answered whatever it was told would pin nothing. The jQuery shim implements
+ * only what the module under test calls.

From 86a803015a6d6357c746c4809ffba0b0b5bdc7e6 Mon Sep 17 00:00:00 2001
From: Douglas Lindsay <dlindsay@two.inc>

Subject: [PATCH 274/885] feat(checkout): sync the billing address from the
 shipping one, and pin it once the buyer edits it (TWO-25461)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The checkout has two address forms — the shipping step's, which core always
renders, and the billing one, which appears per payment method when the buyer
unchecks "My billing and shipping address are the same". Until now there was no
relationship between them beyond an accident: the company-address autofill wrote
its fields with DOCUMENT-WIDE selectors, so it landed in both forms
unconditionally, including one the buyer had already filled in by hand.

This replaces that with the two-address model the sibling plugins already
implement:

- the billing address stays fully editable, always;
- changing country or company on the shipping address propagates to it;
- propagation stops on a pure CONTENT MATCH, not a flag. Before writing, each
  mirrored field's current content is compared (trimmed, case-insensitive)
  against what the plugin last put there. One field that no longer matches pins
  the WHOLE address — not just that field — and nothing is written into any of
  it until the contents come back to matching. There is deliberately no "resume
  sync" control: the match check is the resumption path;
- every field the mirror can write is judged, including address line 2 and the
  state/region, not only country and company;
- an external address payload is routed by rule: a building or apartment takes
  line 1 and pushes the street to line 2, with both joined most-specific-first;
  a street alone takes line 1 and leaves line 2 untouched; there is no
  de-duplication between the lines; and the region lands in the form's own state
  control when the country has one, or is appended to the city with a comma when
  it does not.

The country-switch retraction is now pin-aware too: a pinned billing address is
skipped whole rather than field by field, because clearing the parts of it that
happen to still match would break the same address-wide rule.

Attribution has two records, and needs both: a marker attribute per field, which
is the only record of a write made since the last render, and module state,
which is the only record that survives core rebuilding the form. Neither
survives a page load — a lost record reads as buyer-authored and pins, which is
the safe direction.

Live-verified against a local checkout, which is where the region defect below
was found: a country change repopulates the region select from the new
country's directory data and lands on core's own placeholder option, whose
label is not empty. Reading that label as the buyer's answer pinned a billing
address nobody had touched, permanently. Covered by its own regression test.

Subject: [PATCH 275/885] fix(soletrader): scope the address write and make it
 survive replays (TWO-25461)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Adversarial review round 1 findings on the write-back.

Scope. applyAddress()'s selectors were document-wide, which was tolerable
while a buyer's own search pick was the only trigger and is not now that
a passive prefetch fires it unattended: the payment step keeps the
shipping form in the DOM and renders a billing form per payment method,
all with the same field names, so one write reached every one of them —
and a region id resolved against one form's option list was written into
all of the others, where it is not an option at all. applyAddress() now
takes an optional scope, and the tile passes the billing-role form
(§1(a.3)) while the address-area picker keeps its existing behaviour.

Replays. All three adoption paths can fire for the same buyer, and a
replay overwrote a correction the buyer had since made. The address is
now written once per identity, re-armed when sole-trader mode is left —
which also now takes the address back, the missing half of a discard that
already dropped the identity. The prefetch chain carries a generation and
its own minted token, so a chain superseded by an email edit neither
records its buyer nor acts on it. The popup's message listener is
detached on dispose(), so a re-rendered checkout does not stack one live
writer per render. A throw in the address write can no longer take the
identity fill with it.

Payload handling. A key the payload omits is no longer written as an
empty string — that blanked fields the buyer had filled — while an
explicit empty string still is. Conversely a field this module wrote for
a previous selection is retracted rather than left standing, so an
address cannot end up assembled from two companies. On a shop configured
for one street line the locator and street are joined onto it instead of
the street being written to a field that does not exist. `change` fires
only once every value has landed, so no listener sees the city without
its appended region. Which region control is in play is decided by
whether the select carries real options rather than by CSS visibility,
which also answers "hidden" for a form that is merely on the other step.

The return-value plumbing is gone: it was always truthy, so nothing it
reported was real. Tests grew the cases those defects needed, the spy
jQuery double gained a real attribute store (an inert attr() getter made
every marker assertion vacuous), and two brittle source-greps were
replaced by behavioural cases — the switches are now read through
throwing getters, which covers a gate added in any helper.

Subject: [PATCH 276/885] fix(soletrader): per-element revert, role-first
 scope, retryable write (TWO-25461)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Adversarial review round 2, on the round-1 fixes themselves.

The revert read the marker off a SET and cleared every element in it.
jQuery answers .attr()/.val() from the first match only, so with the
write now scoped to the billing form, the shipping form's unmarked field
decided the answer for every field — the revert on leaving sole-trader
mode, and the one on a country change, both silently did nothing on the
payment step. It also meant one form's marker could authorise clearing a
line the buyer had typed in another. Now checked and cleared per element.

Scope selection: `#billing-new-address-form` went through jQuery's
getElementById fast path and returned at most ONE element, so the loop
meant to pick the selected payment method's form among several could
never see them. Attribute selector instead. Role now beats visibility
too — a hidden billing form is still the invoice address — with
visibility only choosing between forms matching the same selector, and
the shipping form kept as the last resort because core renders no billing
form at all when billing and shipping are the same.

The once-per-identity guard was armed before the write, so a throw or a
checkout with no address form yet consumed the single chance and the
address was never written. It is now recorded only after a write actually
happens, keyed on the email where a buyer has no organisation number, and
held at module scope: a per-instance record is re-armed by the very
re-render it exists to survive.

A completed signup now supersedes a prefetch still in flight — its
pre-auth answer would disagree with the identity the buyer just
authenticated and revert both the mode and the address.

The tile's ordinary company-search selection is scoped the same way as
the write-back; it had the same document-wide reach for the same reason.
A region is written to the free-text control only when that control is
enabled, since Magento disables the one the country does not use and
drops its value on post. And the region is appended to the city only when
this payload is writing the city too: appending to a city the buyer typed
marked their own text as ours, which the next revert would then delete.

Tests: the round-1 mutation survivors are all covered now. Supersession
is exercised after the tokens are minted rather than before, so each
guard is reached individually instead of the first one hiding the rest;
the buyer lookup's token threading runs the real fetchBuyer; and the
"nothing sees a half-written form" invariant is asserted by snapshotting
every field at each change rather than by checking the event sequence,
which could not tell the two apart. The comment that justified it with a
now-impossible city case is corrected.

Subject: [PATCH 277/885] fix(soletrader): match the billing form core actually
 renders (TWO-25461)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Adversarial review round 3.

The billing-form selector matched nothing. Core renders the billing
fieldset with `data-form="billing-new-address"` and no id at all — there
is no `billing-new-address-form` in core on any version, and core's own
tests select it by that attribute — so the scope resolution fell through
to the shipping form every time. The sole-trader write-back landed in the
hidden shipping form on the exact flow it exists for (guest, physical
cart, billing different from shipping), and the tile's ordinary
company-search autofill had been narrowed from document-wide to a form
the buyer was not looking at. Verified against Magento_Checkout's
billing-address/form.html and shipping-address/form.html in a 2.4.6
install; the id is kept after it for third-party checkouts that render
one, and the test fixtures now use core's markup rather than markup the
previous fixtures invented.

The region rule tested `disabled`, which core never sets: its region
element HIDES the control the country does not use (Magento_Ui region.js
hideRegion → setVisible / toggleInput), so the check was inert and the
comment justifying it was wrong on both halves. Back to a visibility test
on the free-text control, with the select's option count — the thing the
country actually drives — still deciding which control is in play.

The once-per-identity record is now keyed per brand: a checkout offering
two Two-family brands renders a tile and a billing form for each, and an
adoption in one says nothing about the other. It is also re-armed on a
country change, where the address step reverts the address it describes.

Subject: [PATCH 278/885] fix(checkout): close eight defects in the two-address
 mirror found by review and live testing (TWO-25461)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Adversarial review across three lenses, plus live verification against a real
checkout, against the first commit of this branch.

Live-found, and neither was reachable by reasoning about the code:

- the DEFAULT address form was mis-identified twice over. Core renders the
  shipping form inline for a buyer with no saved addresses, and inside
  `#opc-new-shipping-address` — whose own `visible:` binding decides it — for a
  buyer with saved ones. A first attempt walked the whole ancestor chain and so
  read the step collapse on the payment step as "core is not using this form",
  silently disabling the entire mirror from that point on; a second inferred it
  from the form having content, which broke the instant a country switch
  retracted the autofill and emptied it. The question is now asked of that
  wrapper, and of its own display only.
- the region abbreviation match was matching an attribute that carries the
  region's own name rather than a code, so it could only ever duplicate the
  label match. Removed, and the fixture no longer stamps a code no store
  renders.

Review-found:

- `revertAutofilledAddress` retired the mirror record for every retractable
  field whether or not it had cleared one. After a form rebuild, when the
  markers are gone and the record is the only surviving evidence, that emptied
  nothing and forgot everything — leaving the previous country's address in the
  billing form attributed to nobody, which the pin reads as a buyer edit and
  freezes permanently. The retraction now follows what was actually cleared, and
  the retraction itself consults the record as well as the marker.
- with no default address form, the write went out through one document-wide
  selector: the region routing decided on one form's option list and applied it
  to all of them, and nothing was recorded, so the next evaluation read the
  plugin's own values as buyer-authored. Written per form now, and recorded.
- the country is mirrored BEFORE the address it belongs to. The store default is
  frequently not the buyer's country, and the region routing reads the target
  form's own option list — so one form selected a state while the other appended
  a state name into its city.
- the organisation number was judged by the pin but never written by the mirror,
  which can only ever freeze an address. It now travels with the company name.
- a replacement pick left the previous company's street stranded on line 2, with
  nothing to pin it because it still matched its own stale record. Line 2 is
  retracted when it holds the plugin's own earlier write, and never when it
  holds the buyer's.
- the baseline could be sealed from a half-built form (core inserts the fieldset
  before its fields render, and `$.async` fires on the insertion), which pinned
  every billing address before the buyer saw it. It now defers until the fields
  are there, is watched off a field rather than the fieldset, and refuses to
  treat a form appearing AFTER the mirror has written as evidence of anything.
- the no-id fallback key was a shared constant, so two billing forms answered to
  one record. Per-node now.

Tests: the three wirings in the address step had no assertion at all — deleting
any one of them left the suite green. Added, with the ordering constraint. Also
added: multi-payment-method independence, the record surviving a form rebuild,
the trimmed/case-folded match as its own table, and a regression for each defect
above, each confirmed to fail without its fix.

469 tests, 33 suites, green. Live-verified end to end with two payment methods:
country propagates to both, a payload routes identically into both, an edit to
one form's address line 2 freezes that form alone, and undoing it resumes the
sync with no control involved.

secondaryAddressKey() is reached for the default shipping form too, via
the retraction path that asks every form what it is on record as having
written. It must answer with no key there — minting one stamps an
attribute onto a form that is not a billing address and burns a key a
real billing form would otherwise have been given.

Subject: [PATCH 280/885] fix(checkout): stop the region routing dropping a
 payload's region with no city (TWO-25461)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Follow-up to #345 (found in post-merge adversarial review). When the
region select has no matching option and the payload carries no city
either, the region had nowhere left to land — silently dropped. The
city-append branch's own describe block already promises "an external
payload's region lands somewhere, always"; this closes the one case
where that wasn't true.

output, wired into install/run/debug's status blocks. No merchant-portal
URL concept exists in this plugin, so only the two hosts that actually
exist (API, checkout) are reported.

Also fixes an intermittent `make install` failure: the base image's own
entrypoint independently bootstraps Magento (4x magerun2 config:store:set
+ cache:flush) once its own MySQL/ES wait loop clears, which isn't gated
by the existing `bin/magento --version` readiness check. Those bootstraps
can autoload-generate classes under generated/code, racing the Makefile's
own `rm -rf generated/code` and intermittently leaving it unable to rmdir
a directory a magerun2 process just wrote a new file into. Reproduced via
docker logs -t timing correlation; fixed by waiting for magerun2 to settle
before touching generated/code.

Subject: [PATCH 282/885] fix: exclude dev/ from PHPStan, rename deprecated
 excludes_analyse

dev/probe-hosts.php bootstraps via app/bootstrap.php and uses the
Magento-defined BP constant, which PHPStan can't resolve outside a
real bootstrap - same reason Test/* is already excluded. Also
renames the config key itself: PHPStan 2.x deprecated
excludes_analyse in favour of excludePaths.

Popup dimensions, hideIframe(), empty-token link, and the branding
mechanism were already fixed by #343 (and checkout_url_template was
already wired correctly). What was left: a "select a different sole
trader" link with an autoselect=false popup param, and an in-flight
spinner for the token-mint/buyer-lookup round trip — both ported from
the WooCommerce/PrestaShop reference implementations shipped earlier
this session.

Subject: [PATCH 284/885] fix(soletrader): close the re-entrancy and spinner
 races review found
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Self-review on PR #348 found three real issues, all in the class §5/§7
of the porting guide predicted (races on every iteration, budget
multiple review rounds):

- No popup-instance tracking: clicking "select a different sole
  trader" while the first adoption's popup was still open could leave
  two live popups, and popupMessageListener() had no way to tell which
  ACCEPTED it was hearing from — the message that landed last won,
  regardless of which tab the buyer actually completed.
- Same gap meant a double-click on either launcher spawned two tabs.
- soleTraderPrefetchInFlight was a shared, non-ref-counted flag: an
  older prefetch call settling after a newer one started (buyer edits
  the email again mid-flight) could clear it while the newer call was
  still genuinely outstanding.

Fixes: openIframe() tracks the one live popup handle and closes any
existing one before opening a new one; popupMessageListener() also
checks event.source against that tracked handle as a second line of
defence; prefetchSoleTrader()'s .finally() only clears the flag if
its own email is still the current one.

4 new regression tests, each mutation-checked red against its fix.

Subject: [PATCH 285/885] TWO-25498: align admin surcharge/payment-terms copy
 and visibility with WC

- Hide Surcharge Line Description when Surcharge Method is None, matching
  its siblings (surcharge_differential/surcharge_tax_class) in
  payment-terms-config.js.
- Title-case Payment Terms/Surcharge admin field+group labels; pluralise
  "Custom/Default Payment Term(s)".
- Hide "Custom Payment Terms (days)" unless its value is genuinely custom
  (not already a merchant-offered term, ticked or not); on save, clear it
  and fold it into the checkbox selection when it duplicates an offered
  term. PaymentTermsCheckboxes reads the sibling's posted value via
  getFieldsetDataValue(), which Magento populates for the whole group
  before any field's beforeSave() runs, so this is independent of
  per-field save order.
- Rename the surcharge grid's "Percentage" column to "Percent of Fee"
  (SurchargeType's own "Percentage" dropdown option is untouched).
- Rewrite the surcharge-grid help paragraphs per spec; the fixed-method
  sentence now only appends "Max <value>." when a cap is configured.
- Update nb_NO/nl_NL/sv_SE translations for changed/added strings
  (machine-translated, needs native review).

Subject: [PATCH 286/885] Rename Availability & Minimum Order section to
 Availability

The minimum order fields are suppressed for brand overlays that
suppress them, making the old label misleading in that state; the
group also covers country availability and order-intent, not just
the minimum order fields.

Subject: [PATCH 287/885] Add FeeLineProviderInterface implementation for
 Amasty Extra Fee

Amasty's quote-side total collector bumps grand_total/tax_amount for a
taxed fee without a matching line item, so getOtherChargesLineItem()'s
untaxed-only fallback refuses to itemize it and checkout-api rejects
the order on a net/tax mismatch (Linear ABN-489). Amasty's
OrderRepository plugin already populates amextrafee_fee_amount/
amextrafee_tax_amount as OrderInterface extension attributes on every
order load, so this reads those directly instead of touching Amasty's
tables.

Subject: [PATCH 288/885] Reload the order via repository to reach Amasty's
 extension attributes

ComposeOrder hands this provider $payment->getOrder() - the in-memory
object from the current placement transaction, never loaded through
OrderRepositoryInterface. Amasty's own OrderRepository plugin only
populates amextrafee_fee_amount/amextrafee_tax_amount on afterGet/
afterGetList, so it never ran on that object and the provider silently
returned no line - reproduced live on staging, still rejected by
checkout-api with the same net/tax mismatch this was meant to fix
(Linear ABN-489). Reloading by entity ID forces Amasty's plugin to run;
the order row is already persisted by the time ComposeOrder executes.

Subject: [PATCH 289/885] Fix stub repository parameter names to match
 OrderRepositoryInterface

PHP requires an implementing class's parameter names to match the
interface exactly, not just types - $entity vs the interface's
$order was a fatal error at class-definition time.

Subject: [PATCH 290/885] Use PHPUnit mocks instead of hand-rolled repository
 stubs

A hand-written anonymous class implementing OrderRepositoryInterface
has to match the interface's parameter types/names exactly, which
differ across the Magento versions CI tests against and caused a
fatal error either way. createMock() generates a compatible stub via
reflection against whatever version is actually loaded.

Subject: [PATCH 291/885] Fix test helper type hint to match the actual stub
 passed in

This repo's unit test bootstrap stubs Magento\Sales\Model\Order as a
plain data bag (Test/Stubs/SalesModels.php) that does not implement
OrderInterface. repositoryReturning() was typed against the interface
while every call site passes the stub Order model - a TypeError on
every test that reached it.

Subject: [PATCH 292/885] Loosen reloadedExtensionAttributes()'s return type to
 object

The method already duck-types every caller via method_exists() rather
than depending on OrderExtensionInterface's real (codegen'd) shape, so
typing the return as that interface was stricter than the code
actually needs - and broke the tests, whose fake extension-attributes
objects have no reason to implement it either.

Subject: [PATCH 293/885] Read Amasty's fee by quote_id instead of reloading
 the order

Verified live on staging that PR #352's reload-via-repository fix
still didn't work - same net/tax mismatch, fresh trace ID. Root cause:
Magento\Sales\Model\Service\OrderService::place() calls $order->place()
(which runs payment authorize(), i.e. ComposeOrder) BEFORE
$orderRepository->save($order). The order ComposeOrder hands this
provider has no entity_id yet, so "reload it via the repository" always
returns nothing - there is no row to reload for anyone, Amasty's own
OrderRepository plugin included.

The order does have a quote_id, because the quote has already been
converted. Amasty's own OrderRepository plugin reads its quote-fee
table by quote_id for exactly this reason; this provider now does the
same lookup, isolated in AmastyExtraFeeQuoteReader since
amasty/module-extra-fee isn't a build dependency of this repo and the
resource-model class can't be type-hinted without breaking DI compile
for merchants who never installed it.

Linear ABN-489.

Subject: [PATCH 294/885] fix(ABN-489): stop the Amasty fee provider pool being
 silently skipped
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Order::__construct() declared feeLineProviderPool as ?FeeLineProviderPool
= null. Magento's object manager auto-wiring does not construct an object
for a nullable-defaulted constructor parameter unless etc/di.xml names it
explicitly for the concrete class, which it never did for
ComposeOrder/ComposeCapture/ComposeRefund — so every real request built an
empty pool via the null-coalescing fallback, and every registered
FeeLineProviderInterface (including AmastyExtraFee) silently never ran.
Making the dependency required lets auto-wiring inject the real,
di.xml-configured pool.

Subject: [PATCH 295/885] Move Two order id into native admin Payment
 Information section
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Replaces the standalone "<brand> Details" order-id row with a row in
Magento's standard Payment Information block, labelled "<brand> order
id" via BrandRegistryInterface. Every brand (base Two, ABN overlay,
future overlays) gets its own label for free through the existing
brand-resolution mechanism — no per-brand override needed. Invoice/
Credit Note download links stay in the existing section, which is
otherwise unaffected.

Subject: [PATCH 296/885] fix(ABN-489): reconcile third-party fee tax
 generically via applied_taxes
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Magento copies the quote address's applied_taxes total data onto the
order's own extension attributes during quote-to-order conversion,
before Order::place() ever runs. Any total-collector extension that
registers its tax with Magento's tax engine (Amasty's Extra Fee
included) shows up there, so Order::findVerifiedResidualTaxRate() can
verify a taxed residual against a rate Magento itself already applied,
with no vendor-specific code and no entity_id needed.

This supersedes the AmastyExtraFee/AmastyExtraFeeQuoteReader provider
added in PR #353/#354 for reconciling Amasty's fee specifically — the
generic mechanism covers it (and any other extension that integrates
with Magento's tax engine the same way) without a per-vendor adapter.
FeeLineProviderInterface remains for the narrower case of an extension
that computes its own tax outside Magento's tax engine.

Subject: [PATCH 297/885] fix(ABN-489): handle both applied_taxes shapes in tax
 reconciliation

findVerifiedResidualTaxRate() only handled applied_taxes entries as
plain arrays. Confirmed live that this is only true briefly, right
after ToOrderConverter::afterConvert() sets it: QuoteManagement::
submitQuote() immediately re-merges that converted order into a fresh
one via DataObjectHelper::mergeDataObjects(), which rehydrates the
array into Magento\Tax\Model\Sales\Order\Tax objects -- the shape
ComposeOrder's $entity actually carries. The array-only check silently
returned null for every real order, so the mechanism never fired live
despite passing CI and unit tests (which only exercised the array
shape). Handles both shapes now, with tests pinning each.

Subject: [PATCH 298/885] docs(ABN-489): fix stale docblock and note
 rate-matching ambiguity

FeeLineProviderPool's constructor docblock still described the inline
empty-pool default in Order.php that PR #354 removed. Also documents
that findVerifiedResidualTaxRate() matches a residual by amount, not
identity: the first applied rate whose implied tax reconciles the
residual wins, with no proof that rate specifically produced this
residual. Narrow in practice (would need two applied rates to coincide
on the same net/tax split), and the emitted gross/net/tax amounts stay
correct regardless -- only the reported tax_rate/tax_class_name label
could be wrong. Found by an independent adversarial review of #354/#356/#357.

Subject: [PATCH 299/885] Rename the tax-subtotals setting to "Validate tax
 subtotals" (TWO-25502)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Aligns the Magento admin label with the cross-plugin name. The config
path stays `enable_tax_subtotals` — renaming it would need a data
migration for no behavioural gain, and WooCommerce/PrestaShop keep the
same key.

Adds the unit coverage the aggregation never had: the config gate, the
per-rate grouping, and the 6-dp rate precision Two's gross_amount
reconciliation depends on.

Subject: [PATCH 300/885] Relay declared tax rates and refuse inconsistent
 lines (TWO-25503)

Four financial-correctness gaps against the WooCommerce/PrestaShop
behaviour:

- A payment term the buyer selected but the merchant no longer offers was
  silently swapped for the default at final placement. It now fails the
  same way the chip-click endpoint already did, through one shared
  availability check.
- The shipping line's tax_rate was computed as tax/net. It is now the rate
  the store's tax engine declared for that line, matching product lines.
- Every composed line's declared tax must follow from its own declared rate
  and net within 0.02 currency units, or the checkout is declined with a
  generic notice.
- A new "Default Shipping Tax Rate" setting covers a taxed shipping line
  the tax engine declares no rate for. Unset by default, and unset means
  refuse the order rather than assume a rate.

+## An optional constructor argument is NOT autowired
+
+A constructor parameter with a default of `null` is left at its default by
+the object manager — it is never resolved from its type hint. Adding a
+dependency that way and relying on DI to fill it in gets you a silent
+`null` at runtime while every unit test (constructor skipped) still passes.
+`bin/magento dev:di:info <class>` reports it as `"_vn_": "string 1"`
+(value null) instead of `"_i_"` (instance); that is the check.
+
+`Service\Order::$orderTaxManagement` is declared optional for constructor
+BC and named explicitly in `etc/di.xml` on the abstract parent, which all
+four `Compose*` subclasses inherit. `Service\Order::$feeLineProviderPool`
+is the same shape but has no `etc/di.xml` argument, so it resolves to null
+in production and its `?? new FeeLineProviderPool([])` fallback — an empty
+pool — is what actually runs; the registered `AmastyExtraFee` provider
+never fires.
+
+## The plugin never derives a tax rate from amounts
+
+A line's `tax_rate` is whatever the store's tax engine declared for that
+line, relayed verbatim. `tax / net` is a different statement: rounding,
+combined rates and a discounted base all put the quotient on a rate no tax
+rule declares, and Two validates the declared rate against the line's own
+amounts.
+
+Product lines read `tax_percent` off the item. Shipping has no such column,
+so `getTaxRateShipping()` reads the shipping-typed item out of
+`OrderTaxManagementInterface::getOrderTaxDetails()` and sums its applied
+taxes. Nothing declared and no shipping tax charged is 0% — a store whose
+shipping is untaxed records no tax row at all, and 0% is a statement rather
+than a guess. Nothing declared but tax charged is the only narrow path that
+consults the "Default Shipping Tax Rate" admin field, and with that unset
+the order is refused rather than given an assumed rate.
+
+`validateTaxReconciliation()` closes the same loop at composition time: a
+line whose declared tax does not follow from its own declared rate and net,
+within 0.02 currency units, declines the checkout with a generic buyer
+notice. It never corrects the numbers.

Subject: [PATCH 301/885] bump PHPUnit 9.6.34 -> 10.5.64 in the Makefile test
 targets

9.x is EOL. 10.5 is the latest line still compatible with the pinned
php:8.1-cli image (11.x requires PHP 8.2+). All 766 tests pass; 11
non-fatal deprecation notices surfaced, no failures.

Subject: [PATCH 302/885] Align the admin/config surface with WooCommerce and
 PrestaShop (TWO-25503)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Batch 3 of the cross-platform parity work — admin and config-surface items.

- Sole-trader autofill is reached ONLY by clicking the chip. The
  email-driven prefetch and its auto-adopt are gone; the chip click mints
  tokens, resolves the buyer and either adopts them or opens signup.
- Address autofill is gated on "Autofill company address" alone, never on
  where the company-search control is mounted. A merchant running search
  in the payment tile previously got no autofill at all.
- The API key field verifies as it is typed (debounced) and, on save, a
  key the API definitively rejects aborts the save instead of replacing a
  working one.
- The fulfilment-status mapping says out loud that an empty mapping means
  Two is never notified of fulfilment.

Subject: [PATCH 303/885] Cross-validate terms at submit and dispatch lifecycle
 events (TWO-25503)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Batch 4 of the WooCommerce/PrestaShop parity sweep — checkout and admin UX.

- The selected payment term is cross-checked against the live term set
  immediately before submit, instead of posting a term the API will refuse.
- Four order-lifecycle events (created/completed/cancelled/refunded) are now
  dispatched for downstream integrations; the plugin previously only
  subscribed to core events.
- A missing FX rate for the surcharge withdraws the payment method and
  refuses placement, rather than throwing out of the totals collector and
  making checkout unrecoverable.
- Enabling percentage mode scans stored limits for terms the grid does not
  render, so a stale zero cap surfaces then rather than silently clamping the
  fee later.
- The minimum-order help text gets its own wording for a platform floor that
  cannot be projected into the store base currency.
- Company-search "unavailable" copy matches the sibling plugins.

Subject: [PATCH 304/885] Offer the three company-capture options as peers
 (TWO-25503)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Aligns the payment tile with WooCommerce and PrestaShop: one control with
Registered Organisation / Sole Trader / Enter manually as peer chips,
replacing a two-item tab bar plus a separately worded "My company is not on
the list" button that made manual entry reachable only by opening the search
picker and rejecting its results.

Presentation and routing only — each mode's own behaviour is untouched.

+ * TWO-25503 — the three company-capture options as peers in ONE control.
+ *
+ * The tile used to present a two-item tab bar (registered organisation / sole

+ * Mutation-resistance notes:
+ *
+ *  - the template assertions read the mode control's OWN markup slice, and
+ *    each chip's selected state is asserted to be a binding against
+ *    `captureMode()`. A statically selected chip — which is exactly what the
+ *    old two-block markup had — fails, so re-hardcoding a selection cannot
+ *    pass;
+ *  - the behavioural assertions read real state after the real transition
+ *    (`companyId()`, the field's value, the recorded control calls), never
+ *    that a method exists. Emptying `manualEntryMode()` fails every one;
+ *  - the chip gating is asserted by nesting, so moving a chip out of its
+ *    `ko if` (making sole trader offerable in a country whose registry has no
+ *    sole traders) fails rather than reading as green.

Subject: [PATCH 305/885] fix PHPStan void-return violation in
 ApiKey::beforeSave()

Encrypted::beforeSave() (the parent) has no return statement, so
`return parent::beforeSave();` used a void result. Split into a
statement call + bare return, matching the parent's own contract.

Subject: [PATCH 306/885] Read the declared shipping tax rate at placement time
 (TWO-25503)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

At order composition the order is not yet persisted — ComposeOrder runs
from Two::authorize() inside Order::place(), before the repository save —
so it has no entity id and no sales_order_tax_item rows. Reading the rate
through OrderTaxManagementInterface therefore always came back empty at
checkout, and every taxed-shipping order either fell back to the static
default rate or was refused outright.

Read the order's own item_applied_taxes extension attribute first, which
quote->order conversion populates in memory, and keep the persisted read
for the post-save consumers (capture, refund).

Subject: [PATCH 307/885] Fit tax reconciliation and key verification to real
 configurations (TWO-25503)

A flat 0.02 reconciliation tolerance assumes one rounding, on the line, and
tax computed on the same base as net_amount. Two supported Magento
configurations break both assumptions: the "Unit Price" algorithm rounds per
unit and sums, so the residual grows with quantity, and "Before Discount" tax
calculation taxes the undiscounted base. Both were common enough to decline
ordinary checkouts. Scale the tolerance with quantity and accept
net + discount as an alternative base.

Separately, the API key backend model verified a candidate against the
COMMITTED mode, so switching sandbox -> production and pasting the production
key in one save checked the new key against the old environment, took a 401
and failed the whole section save. Verify against the mode submitted in the
same request.

Subject: [PATCH 308/885] Wire the fee provider pool, guard the term sources
 and the lookup race (TWO-25503)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Service\Order::$feeLineProviderPool and FeeLineProviderPool::$logRepository
are optional constructor arguments, which the object manager leaves at null,
so the registered Amasty Extra Fee provider never fired and the pool's own
rejections were never logged. Named in etc/di.xml, verified with
dev:di:info.

The order payload's payment term comes from additionalData while the
surcharge is priced off the session term /select-term writes, and nothing
checked the two agreed — a /select-term call that failed mid-flow could
place an order on one term carrying the other's fee. Cross-check them at
composition, and refuse a non-numeric term rather than letting it cast to
the default.

A second sole-trader chip click landing while the first lookup was still in
flight hit the dedupe key and resumed immediately on a lookup that had
minted nothing: no adoption, no popup, and no fallback link either. Return
the outstanding chain instead.

Subject: [PATCH 309/885] Multishipping dedupe, i18n keys and stale comments
 (TWO-25503)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

LifecycleEventDispatcher deduped on the entity id, which is null during
placement, so under multishipping every order after the first was deduped
away and two_payment_order_created never fired for them. Fall back to the
increment id.

Also: guard the fulfilled-order id read like its sibling key; re-key the
nb/nl/sv rows for the two reworded admin comments and add the API-key
spinner string; and correct comments that no longer describe what the code
does — the surcharge FX gate fails open and relies on the placement
backstop, openDropdown is threaded through rather than set here, and the
totals collector's throw came out of the calculator's own conversion.

Subject: [PATCH 310/885] Fix API-key live-check scope resolution and two
 log/race nits (TWO-25503)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Final adversarial review round found:
- ApiKeyCheck::getScope()/getScopeId() read the element's own form (the
  fieldset, which carries no scope) instead of the config Form block
  the renderer is actually bound to at render time — the live check
  silently verified against the default scope's environment regardless
  of which store view was open. Same false-confidence class the save

Subject: [PATCH 311/885] Add client/client_v identification params to
 company-search endpoints (TWO-25503)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Both the company-search and address-lookup-by-id calls hit unauthenticated
browser-facing endpoints without identifying the calling plugin, unlike
gateway_method.js's order_intent call — forcing a CORS preflight on every
keystroke instead of skipping it via client/client_v.

Subject: [PATCH 312/885] Couple address autofill to company-search placement
 (TWO-25503)

Doug's ruling: "Enable company search in address entry" OFF relocates
search to the payment tile rather than disabling it, but retires the
convenience "Autofill company address" exists for, so autofill is
forced off with it. Repository::isAddressSearchEnabled() now ANDs both
flags (gates the read, matching PrestaShop's resolver), a new
AddressSearchToggle backend model pins the stored value off on save
(matching PrestaShop's save-time guard and WooCommerce's admin.js
disable-and-uncheck), and system.xml/brand_form_template.xml grey the
field out via <depends> when the parent is off.

Subject: [PATCH 313/885] Brand the fulfilment-mapping admin help text
 (TWO-25503)

The "Fulfilment order status" comment hardcoded "Two is never notified".
A new CommentInterface model resolves the active brand's product name,
following the same pattern already used for the minimum-order-value
field, so an overlay needs no per-brand override for this text.

"Registered Organisation"/"Sole Trader" become "Registered company"/
"Sole trader" to match the other platforms' exact copy; nb_NO/nl_NL/
sv_SE translations ported from prestashop-plugin's existing values.

Subject: [PATCH 315/885] Read .env before .env.local so a real TWO_API_KEY
 isn't silently ignored

Makefile only included .env.local, so a repo-root .env was never read and
make install fell back to TWO_API_KEY=dummy-dev-key. Layer .env (base,
gitignored) under .env.local (personal overrides), matching the include
order woocommerce-plugin already uses, and add a tracked .env.example.

Subject: [PATCH 317/885] fix(checkout): bind company_name required to
 isTileCompanySearchActive (TWO-25503)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The visible: binding on the field wrapper only sets display:none; it never
touched the input's required attribute, which stayed a static required="true".
Native HTML5 constraint validation still blocks form submission on a required
field that isn't rendered, silently (no bubble, nowhere to point it) — this
was blocking Place Order on the Sole Trader path with no visible error and no
network request, matching WooCommerce's twoinc.js pattern of toggling the
required attribute itself rather than relying on visibility alone.

Subject: [PATCH 320/885] PDEV-4669: send the buyer's country to the
 sole-trader signup popup

openIframe() built the hosted signup URL with no country param, so
the popup always defaulted its whole form to GB regardless of the
buyer's actual country -- for a US buyer this meant registering as a
GB sole trader and never seeing the US Onfido biometric-consent step,
which only renders when the URL carries &country=US.

Sourced from quote.billingAddress().countryId, the same server-
resolved value getAutofillData() already puts in
billing_address.country_code, not from countryCode() (partly DOM-fed)
-- so a buyer cannot dodge the extra step by picking a different
country client-side. Mirrors the fix shipped for PrestaShop in
PDEV-4669 / prestashop-plugin PR #178.

Subject: [PATCH 321/885] fix(TWO-25503): drop di.xml references to classes
 that do not exist
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Service\Fee\Provider\AmastyExtraFee was deleted in c5ed9e1 when the
third-party fee tax reconciliation went generic, and 1d31e3b re-added the
<item> pointing at it. The ObjectManager resolves that argument while
constructing FeeLineProviderPool, so Service\Order and every subclass —
ComposeOrder, ComposeCapture, ComposeRefund — plus Model\Two itself throw
a ReflectionException: checkout, capture and refund return HTTP 500 on
staging today.

setup:di:compile validates the XML but never resolves an <item>'s class,
and unit tests run without an ObjectManager, so nothing in CI saw it.
DiConfigClassReferencesTest closes that gap by asserting every
Two\Gateway class named in etc/di.xml is on disk. It also caught the dead
<type name="Two\Gateway\Logger\Handler"> block, a directory rather than a
class since the module's first commit; the handlers get their filesystem
argument from core's DriverInterface preference regardless.

Subject: [PATCH 322/885] fix(TWO-25503): write sole-trader buyer phone number
 to checkout

adoptSoleTraderBuyer() wrote the buyer address via the shared
applyAddress(), which deliberately never writes telephone (correct for
an ordinary registry lookup, not for this buyer's own verified
record). Matches WC PR #496 and PrestaShop PR #186.

Subject: [PATCH 323/885] TWO-25503: gate the manual-entry chip on address-area
 company search

Manual entry cannot capture a company number, which the payment method
requires, so the chip is offered only where the address-step lookup is
available.

The predicate's doc claimed manual entry is offered only where the
address-step lookup is available, which is the inverse of what the gate
does. Restates the real reason, and refreshes the surrounding comments
the gate made stale.

A stale worktree left there duplicates every class under Test/ against the main checkouts copy, so composer/Magentos install-time class discovery fatals on a duplicate declaration. Shadow the subdirectory with an empty tmpfs inside the container instead of relying on worktree hygiene.

Subject: [PATCH 326/885] refactor(TWO-25503): move the sole-trader flow into
 its own model

The payment tile's Knockout renderer owned the whole sole-trader capture
flow. WooCommerce and PrestaShop both keep it in a sibling of their
company-search module (twoincSoleTrader, TwoSoleTrader.js); Magento was
the outlier. Extracted verbatim into Two_Gateway/js/model/sole-trader,
with gateway_method.js left as thin delegates over it.

Behaviour is unchanged. The one deliberate difference: the popup
handshake now requires a tracked popup handle before matching
event.source, so a null-source message cannot be accepted in the window
before any popup has been opened.

Subject: [PATCH 327/885] refactor(TWO-25503): give the company-search mount
 the chips it owns

The three-chip mode selector, the manual-entry gate and the tile's whole
company-search mount lived in the payment renderer. WooCommerce and
PrestaShop both keep the chips with the company-search component
(TwoCompanySearch's chip builders, twoincCompanyCapture); Magento was
the outlier. Extracted into Two_Gateway/js/model/company-capture, with
gateway_method.js left as thin delegates over it.

Behaviour is unchanged. Across both halves of the split gateway_method.js
drops from 2558 to 1690 lines.

+ * TWO-25503: which of the three company-capture options the buyer is in, and
+ * the company-search mount that two of them drive.
+ *
+ * Magento's counterpart to the chip half of PrestaShop's `TwoCompanySearch`
+ * (`renderChipSelection`, `syncRegisteredEntryVisibility`,
+ * `syncSoleTraderEntryVisibility`, `syncNotListedVisibility`) and to
+ * WooCommerce's `twoincCompanyCapture` + `TwoCompanySearch` chip builders. On
+ * all three platforms the chips belong to the company-search component; before
+ * this they were the one part of it Magento kept inside the payment tile's
+ * Knockout renderer, which is what made that renderer a second, parallel
+ * implementation rather than a mount.
+ *
+ * Owns: the three mode entry points, which chips are offered, where the one
+ * shared search control lives on this checkout, that control's whole
+ * lifecycle, and the country the search runs against.
+ *
+ * The HOST is whatever mounts this — today the payment tile's Knockout
+ * renderer. The mode observables, the company identity observables and their
+ * writers, and the sole-trader flow are all reached through it. What is
+ * private to the mount — the `CompanySearchControl` instance and the delegated
+ * country watcher's namespace — is this object's own state.
+ *
+ * @see view/frontend/web/js/model/sole-trader.js for the flow behind the
+ *      sole-trader chip.

+     * search API's own default (US) whatever the buyer had selected, on
+     * one-page checkouts (Fire Checkout) only.
+     *
+     * Why only there: `countryCode()` had exactly two feeds — the
+     * `countryCode` customer-data section, written ONLY by
+     * address-autocomplete.js's toggleCompanyVisibility()/onCountryChanged()
+     * once `$.async('#shipping-new-address-form select[name="country_id"]')`
+     * resolves, and updateAddress(), which reads the country off the quote's
+     * PERSISTED billing/shipping address. On Luma and Amasty the first feed
+     * fires on every country change, so the observable is current before the
+     * buyer can search. A one-page checkout supplying its own address markup
+     * matches neither that selector nor — until the address is saved — has a
+     * persisted quote address to read, so `fillCountryCode()`'s
+     * `if (!countryCode) return;` left the observable at its `''` default,
+     * and buildSearchAjaxOptions() put an EMPTY `country=` on the search
+     * URL, which the API answers under its own default.
+     *
+     * The real fix is the THIRD feed added by watchAddressFormCountry()
+     * below, which keeps `countryCode()` current on any checkout. This
+     * getter is the belt-and-braces on top of it: the observable FIRST,
+     * because it is the authoritative value (quote-derived, and now
+     * DOM-driven too), and a direct DOM read only when it is still empty —
+     * i.e. only in the window before anything has resolved a country at all,
+     * which is exactly the state that produced the bug.
+     *
+     * That order matters and is not interchangeable. DOM-first was tried and
+     * rejected in adversarial review: core renders `#shipping-new-address-form`
+     * inside the HIDDEN new-address modal for a customer who has saved
+     * addresses, and renders one billing-address form PER payment method, so
+     * a DOM-first read could let an untouched form's STORE DEFAULT country
+     * beat a correct quote-derived one — reintroducing the same class of bug
+     * on the platforms that worked.
+     *
+     * TWO-25461 §1(a.3): the tile has no address fields of its own, so its
+     * country is the BILLING/INVOICE-role address's — and every feed below is
+     * shipping-biased in some state, so a buyer shipping to one country and
+     * invoicing in another could search the wrong registry.
+     *
+     * `quote.billingAddress()` rather than a live read of the billing form:
+     * billing is Magento's non-default form, and §1(a.3) says its value comes
+     * from the sync mechanism (core's own same-as-shipping copy into the
+     * quote). It is also the source getAutofillData(), getData() and
+     * placeOrderIntent() already read, so this is one resolution reused
+     * rather than a fourth mirror. Accepted cost: while the buyer is editing
+     * the billing form and has not applied it, the quote holds the previous
+     * country.
+     *
+     * This getter feeds the SEARCH. Sole-trader availability and the

Subject: [PATCH 328/885] refactor(TWO-25503): self-review follow-ups

Repoint three sibling-file comments at the file that now owns the code
they cite, drop a CompanyCapture entry point nothing calls, and drop the
mage/url dependency gateway_method.js no longer uses.

Adversarial review round 2 found two references in company-search.js
still naming gateway_method.js for the select2 mount and for

Subject: [PATCH 330/885] test(TWO-25503): share one sibling instance per
 harness load
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The sibling auto-load added with this refactor re-evaluated a module on
every resolution, so two siblings requiring the same third module would
each get their own copy and split module-scope state production shares.
Only company-capture and sole-trader take that path today and each is
required once, so nothing was wrong yet — but the state it would split
is load-bearing.

Subject: [PATCH 332/885] refactor(TWO-25503): page-level company-capture
 component
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Replaces the payment-tile-scoped company-search/sole-trader container
with one component per checkout page, matching WooCommerce's
`class TwoCompanySearch` and PrestaShop's `TwoCompanySearch.js`.

The old container was re-created on every totals change (Luma, Amasty
and Fire Checkout all rebuild payment renderers), and it split chip
ownership from mount ownership across two modules. Both sibling
platforms keep them in one component that outlives any render. Three
rounds of review on the previous attempt kept surfacing the same defect
wearing different hats — state whose lifetime was per-render standing in
for something page-level — which is what made replacing the container,
rather than patching it, the fix.

- company-identity.js: the captured company, one write path.
- company-capture-component.js: the chips (built in JS as a sibling of
  the live field, as both platforms do) and the ONE search control,
  re-pointed between the address step and the tile rather than
  duplicated.
- sole-trader.js: page-level; tokens, popup, close watcher, handshake.
- company-search-boot.js + one sidebar layout node: constructed once,
  deliberately not under a payment renderer.
- company-capture.js and the Knockout chip block: deleted.

Carries forward the verified behaviour from the previous attempt:
tokens minted on availability rather than on click, no passive buyer
probe before authentication, a synchronous click-to-window.open() path,
the 30-minute refresh, autoselect=false on re-signup, abandoned-popup
handling, and an error surfaced on a non-ACCEPTED message.

-     * search API's own default (US) whatever the buyer had selected, on
-     * one-page checkouts (Fire Checkout) only.
-     *
-     * Why only there: `countryCode()` had exactly two feeds — the
-     * `countryCode` customer-data section, written ONLY by
-     * address-autocomplete.js's toggleCompanyVisibility()/onCountryChanged()
-     * once `$.async('#shipping-new-address-form select[name="country_id"]')`
-     * resolves, and updateAddress(), which reads the country off the quote's
-     * PERSISTED billing/shipping address. On Luma and Amasty the first feed
-     * fires on every country change, so the observable is current before the
-     * buyer can search. A one-page checkout supplying its own address markup
-     * matches neither that selector nor — until the address is saved — has a
-     * persisted quote address to read, so `fillCountryCode()`'s
-     * `if (!countryCode) return;` left the observable at its `''` default,
-     * and buildSearchAjaxOptions() put an EMPTY `country=` on the search
-     * URL, which the API answers under its own default.
-     *
-     * The real fix is the THIRD feed added by watchAddressFormCountry()
-     * below, which keeps `countryCode()` current on any checkout. This
-     * getter is the belt-and-braces on top of it: the observable FIRST,
-     * because it is the authoritative value (quote-derived, and now
-     * DOM-driven too), and a direct DOM read only when it is still empty —
-     * i.e. only in the window before anything has resolved a country at all,
-     * which is exactly the state that produced the bug.
-     *
-     * That order matters and is not interchangeable. DOM-first was tried and
-     * rejected in adversarial review: core renders `#shipping-new-address-form`
-     * inside the HIDDEN new-address modal for a customer who has saved
-     * addresses, and renders one billing-address form PER payment method, so
-     * a DOM-first read could let an untouched form's STORE DEFAULT country
-     * beat a correct quote-derived one — reintroducing the same class of bug
-     * on the platforms that worked.
-     *
-     * TWO-25461 §1(a.3): the tile has no address fields of its own, so its
-     * country is the BILLING/INVOICE-role address's — and every feed below is
-     * shipping-biased in some state, so a buyer shipping to one country and
-     * invoicing in another could search the wrong registry.
-     *
-     * `quote.billingAddress()` rather than a live read of the billing form:
-     * billing is Magento's non-default form, and §1(a.3) says its value comes
-     * from the sync mechanism (core's own same-as-shipping copy into the
-     * quote). It is also the source getAutofillData(), getData() and
-     * placeOrderIntent() already read, so this is one resolution reused
-     * rather than a fourth mirror. Accepted cost: while the buyer is editing
-     * the billing form and has not applied it, the quote holds the previous
-     * country.
-     *
-     * This getter feeds the SEARCH. Sole-trader availability and the

-            TWO-25503: ONE control offering the three company-capture options
-            as peers, matching WooCommerce and PrestaShop. It replaces a
-            two-item tab bar (registered / sole trader) plus a separately
-            worded "My company is not on the list" button inside the search
-            dropdown, which made manual entry reachable only by opening the
-            picker and rejecting its results.
-
-            Deviation from WC/PS, forced rather than chosen: both siblings
-            build the chip group INSIDE the open picker, as a sibling of the
-            results list, because their picker stays alive across every mode.
-            Magento's sole-trader and manual modes both tear the select2
-            widget down (enterSoleTraderUi/clearCompany), so chips living in
-            the dropdown would be unreachable from exactly the two modes that
-            need a way back. They therefore stay in this persistent control.
-
-            Which chips render is per-option, not per-control:
-              - registered is unconditional — it is also the way OUT of the
-                other two, and that has to work on a checkout whose search
-                control lives in the address area;
-              - sole trader follows showModeTab (the billing country's
-                registry supports SOLE_TRADER);
-              - manual entry follows showManualEntryChip(): it acts on the
-                tile's own company-name field, so where the address area owns
-                the search control instead it belongs to that mount and its
-                own in-dropdown button; and with the address-area setting off
-                it is not offered at all, because no address-step lookup then
-                exists to supply the company number the method requires.

-                    TWO-25326, 2026-08-04 ruling (supersedes the §7/§7.1
-                    capture-state and decline-recovery gating that used to
-                    live in this comment — Doug's exact words: "the search
-                    control ... is controlled ONLY by the state of the
-                    'enable search in address' admin setting: if true,
-                    search control is rendered inside the address block,
-                    otherwise is rendered inside the payment tile — and
-                    search control visibility is not changed for any other
-                    reason").
-
-                    So this field's visibility depends on ONE thing —
-                    isTileCompanySearchActive(), the live read of that single
-                    admin setting (plus the saved-address/virtual-cart
-                    fallback documented on that method in gateway_method.js,
-                    which is the SAME condition, not a second one). It no
-                    longer depends on isCompanyCaptured() or on any
-                    order-intent outcome: the control stays visible after a
-                    company is picked, whether the subsequent order-intent
-                    call approves, declines, or errors. The org-number label
-                    below (not the notice sentence) is now the one thing that
-                    changes on capture.
-
-                    The previous behaviour hid this field once
-                    isCompanyCaptured() went true, on the theory that the
-                    order-intent notice sentence made an editable, visible
-                    control redundant — and only re-showed it on a decline,
-                    via isCompanyRecoveryNeeded(), to avoid a dead end for a
-                    buyer with no other route to pick a different company.
-                    Doug found this INCORRECT in live testing on 2026-08-04:
-                    the control was disappearing when a company was picked
-                    and, on the common path (order intent approves), never
-                    coming back — with nothing marking that as intentional
-                    from the buyer's side. This ruling removes that coupling
-                    entirely rather than patching it again.
-
-                    `visible:`, not `if:`, for the same reason as before:
-                    it keeps the node in the DOM so the select2 binding, its
-                    MutationObserver rebinding and the sole-trader write path
-                    all keep working untouched; `if:` would destroy and
-                    rebuild the node under them.
-
-                    Hiding (when isTileCompanySearchActive() is false) also
-                    takes this `required` input out of jQuery Validation's
-                    way — `elements()` skips hidden fields, and that state is
-                    exactly the one where the buyer has the address-area
-                    control instead.

+                    the address step is the other. `visible:`, not `if:` — the
+                    component resolves its mount by this node's presence in the

Subject: [PATCH 333/885] feat(TWO-25503): identify the caller on Two's browser
 endpoints
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

`merchant` was reported as unavailable; it is not. ConfigProvider already
ships the whole memoised verify_api_key record as
`orderIntentConfig.merchant`, so the short name is client-side already —
no new config path and no second live call from the browser.

One `apiClientParams()` builder now serves all three browser calls
(company search, the company detail lookup, the sole-trader autofill
read), so they cannot drift. Absent keys are omitted rather than sent as
the string "undefined", which an object literal handed to
URLSearchParams would do.

jquery joins devDependencies: the capture component owns real DOM now,
and asserting its chips through a hand-rolled double would prove nothing
about the nodes buyers get.

+ * TWO-25503 — the three company-capture options as peers in ONE control, owned
+ * by the company-capture component.
  *
- * The tile used to present a two-item tab bar (registered organisation / sole
- * trader) and reach manual entry only through a separately worded button
- * inside the search dropdown, so a buyer who wanted to type a name by hand
- * had to open the picker and reject its results first. WooCommerce and
- * PrestaShop both offer all three as peer options in one control; this pins
- * Magento doing the same, each chip subject to its own gate.
+ * The chips are DOM, built by the component as a sibling of the field they act
+ * on, the way WooCommerce (`syncSoleTraderChip`/`syncManualEntryButton`) and
+ * PrestaShop (`renderChipSelection`) both build theirs. They are asserted here
+ * against the real nodes the component produces, not against template markup:
+ * a payment-tile template is destroyed on every totals change, which is the
+ * whole reason chip ownership moved.
  *
  * Mutation-resistance notes:
  *
- *  - the template assertions read the mode control's OWN markup slice, and
- *    each chip's selected state is asserted to be a binding against
- *    `captureMode()`. A statically selected chip — which is exactly what the
- *    old two-block markup had — fails, so re-hardcoding a selection cannot
- *    pass;
- *  - the behavioural assertions read real state after the real transition
- *    (`companyId()`, the field's value, the recorded control calls), never
- *    that a method exists. Emptying `manualEntryMode()` fails every one;
- *  - the chip gating is asserted by nesting, so moving a chip out of its
- *    `ko if` (making sole trader offerable in a country whose registry has no
- *    sole traders) fails rather than reading as green.
+ *  - selected state is read off the real class after a real mode transition,
+ *    so hardcoding a selection on one chip fails;
+ *  - each chip's gate is asserted by the node's own hidden state under both
+ *    values of its gate, so making sole trader offerable in a country whose
+ *    registry has none fails rather than reading as green;
+ *  - the click assertions drive the real handler and read the resulting mode,
+ *    never that a method exists. Emptying `manualEntryMode()` fails them.

Subject: [PATCH 334/885] test(TWO-25503): pin the page-level container's own
 guarantees

Every case here fails against the payment-tile-scoped architecture this
replaced: the component is constructed once and only by the boot
component, a tile re-render takes neither the captured identity nor the
sole-trader flow with it, one search control is re-pointed rather than
duplicated, and the merchant setting decides where the control mounts
rather than whether a company can be captured at all.

Writing them surfaced a real defect: mountSelector() dereferenced the
brand config, which stays null on a checkout with no Two method, so the
boot component's totals subscription threw on every totals change.

Subject: [PATCH 335/885] test(TWO-25503): sole-trader suites against the
 page-level flow
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Retargets the five sole-trader suites from renderer delegates onto the
component-owned flow, and re-pins the behaviours carried over from the
previous attempt: tokens minted on availability rather than on click, a
synchronous click-to-window.open() path, the 30-minute refresh skipped
while a round trip is outstanding, autoselect=false on both re-signup
routes, a blocked popup's retry reusing the blocked launch's options,
abandonment deferring to the handshake, and the flight settling only
once the identity write has landed.

Two get stronger proofs than before. The absence of a passive buyer
probe is pinned in source — exactly one `fetchBuyer` call site, inside
the ACCEPTED branch — because it is a security property and a
behavioural fixture alone would not catch its return. The phone write is
proven against the real search model and a real form: applyAddress()
handed a record carrying a phone number leaves telephone untouched.

- * TWO-25461. Two buyer-identity lookups share one helper and must NOT share
- * one rule.
+ * TWO-25503 — the `postMessage` handshake the hosted signup finishes on, and
+ * the one buyer lookup it is allowed to make.
  *
- * `lookupSoleTrader()` is pre-auth: it reads whatever buyer the Two cookie
- * happens to identify before the buyer has proved anything, so a
- * buyer only counts when its email equals the one entered on the checkout
- * form. That check is correct there and is pinned below as a regression guard.
+ * `/autofill/v1/buyer/current` answers with whatever buyer the Two cookie
+ * identifies. Reading it BEFORE the buyer has authenticated is a cookie probe:
+ * it would let a checkout adopt an identity nobody on this page proved they
+ * hold. So the flow has exactly one caller — the ACCEPTED branch of the
+ * handshake, after the hosted flow has verified the buyer server-side — and
+ * that is pinned both behaviourally and in the source, because reinstating a
+ * passive probe is invisible to every fixture that drives the handshake.
  *
- * `popupMessageListener()`'s `ACCEPTED` branch is POST-AUTHENTICATION: the
- * buyer has just completed verification server-side, and the email that
- * authenticated is the identity. It used to re-run the same email-match
- * comparison and, on a mismatch, take no branch at all — the buyer finished
- * signup and got a permanently blank readonly/required company field with no
- * route forward. `resolveBuyer(authenticated)` is what separates the two.
- *
- * `fetchBuyer()` is stubbed per test rather than driven through `fetch`: the
- * behaviour under test is which buyer the two call sites ACCEPT, not how the
- * buyer is transported. `getTokens()` is stubbed for the same reason.
+ * Post-authentication the email that authenticated IS the identity: the
+ * checkout's own contact field has no say in it. Re-gating on a match there
+ * discarded an authenticated buyer and left the company field permanently
+ * blank with no route forward (TWO-25461).

- * TWO-25461 — the three defects in the sole-trader signup popup launch path.
+ * TWO-25503 — the hosted sole-trader signup popup: how it is launched, what it
+ * is launched with, and what happens to the checkout while it is open.
  *
- * 1. The popup opened 610px wide, narrower than the hosted signup flow's own
- *    minimum layout width (700), which clipped it.
- * 2. The note's overlay element bound a click to `hideIframe()`, a method that
- *    exists on nothing. It was the last remnant of a removed in-page iframe
- *    modal (no `.iframe-parent` markup survives, and nothing adds the `.show`
- *    class its stylesheet needs), so the element was permanently invisible and
- *    the broken binding only latent — an overlay stylesheet making it visible
- *    was all it took to turn a click into a TypeError. The element is gone.
- * 3. The "popup not ready" branch offered the fallback link before the signup
- *    tokens were minted, so clicking it built
- *    `…?businessToken=&autofillToken=…` — a URL the hosted flow rejects.
+ * The flow is PAGE-LEVEL (`model/sole-trader.js`), constructed by the
+ * company-capture component with that component as its host, so everything
+ * below drives either the real flow against a stub host or the real component
+ * with the real flow underneath it. Nothing here reaches through a payment
+ * renderer, which no longer participates.
+ *
+ * Mutation-resistance notes:
+ *
+ *  - the mint is asserted to have happened with the popup count still zero and
+ *    no chip clicked, so moving it into the click handler fails rather than
+ *    reading as green;
+ *  - the click assertion runs in the SAME TICK as the click, with no await
+ *    between: an `await` introduced anywhere on the launch path leaves the
+ *    popup unopened at the assertion, which is exactly what a popup blocker
+ *    would do;
+ *  - the country param is read back off the URL under a host whose own
+ *    `countryCode()` throws, so sourcing it from the DOM-fed value fails;
+ *  - the busy flag and the abandon callback are read after driving the real
+ *    watcher tick, never by asserting a method exists.

- * TWO-25461 §7 — the two UX gaps left after the popup-launch bugfixes
- * (PR #343): the "select a different sole trader" link/autoselect param,
- * and the in-flight spinner for the chip lookup's round trip.
+ * TWO-25461 §7 — re-signing up as a different sole trader.
+ *
+ * Two routes reach the same place: the payment tile's "Select a different sole
+ * trader" link, and re-clicking the sole-trader chip once one is already
+ * adopted. Both must carry `autoselect=false`, or the hosted flow silently
+ * re-picks the registration the buyer is trying to replace and hands back the
+ * identity already on screen — a dead end with no visible cause.
+ *
+ * The tile no longer owns the flow. It delegates to the page-level
+ * company-capture component, which is what survives the payment-method list
+ * being rebuilt on every totals change, so the link's own case below is a
+ * delegation check and the behaviour is driven through the real component.

Subject: [PATCH 336/885] fix(TWO-25503): restore the two affordances the mount
 lost
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Both were live before the component took over the mount, and both died
because the new mount did not pass what the old call sites did.

The company field showed nothing when empty: select2 renders its own
display node, so the placeholder belongs to templateSelectionFallback
and not to the input underneath. The msgid was still sitting in three
catalogues with nothing referencing it.

The "Search for company" link was built, hidden, and never shown again —
manual entry is what used to reveal it. A buyer who has just typed into
that field is looking at it rather than at the chips, so the in-field
route back earns its place beside the chip that does the same thing.

Test suites for company search retargeted onto the single mount.

Subject: [PATCH 337/885] fix(TWO-25503): seed the country baseline at boot

TWO-24867 was broken end to end: `_lastCountry` was written only inside
onCountryChanged(), so the first switch after page load read as the first
resolution and kept the company. A buyer could capture a GB organisation
number, move to Spain, and place the order with it.

The old renderer compared against an observable the quote seeded on load;
the component had no counterpart until now.

Remaining suites retargeted onto the single mount, and the control's
docblock no longer argues for the two-mount design it used to have.

- * Luma and Amasty render the core `#shipping-new-address-form` markup, so
- * feed 1 fires on every country change and the observable is current before
- * the buyer can search. A one-page checkout that supplies its own address
- * markup matches neither that selector, nor — until the address is saved —
- * has a persisted quote address to read; `fillCountryCode()` early-returns on
- * an empty value, so the observable stayed at its `''` default and
- * buildSearchAjaxOptions() put an EMPTY `country=` on the search URL.
- *
- * Fixed by sourcing the tile's search country from the buyer's actual
- * `<select>` first (companySearch.currentAddressFormCountry(), a priority list
- * of address-form selectors ending in a catch-all), with the observable kept
- * as the fallback for the checkouts that genuinely have no address-form select
- * — a saved address and a virtual cart.
+ *  1. the quote's BILLING address — the tile has no address fields of its own
+ *     and captures as the invoice role, so a buyer shipping to one country and
+ *     invoicing in another must search the one they invoice in;
+ *  2. the buyer's live address-form `<select>`, via a priority list of
+ *     selectors ending in a catch-all — the fallback for the window before the
+ *     quote holds an address at all, which is the TWO-25326 state.

- * The payment tile's company display, as the TWO-25326 2026-08-04 ruling
- * now defines it. Two things changed from the 2026-08-03 (§7.3) shape this
- * file used to pin, and they are independent:
+ * The payment tile's company display.
  *
- *  - Bug A: the capture CONTROL's (the field + picker) visibility is no
- *    longer gated on isCompanyCaptured() or on any order-intent outcome at
- *    all. Doug's exact words: it "is controlled ONLY by the state of the
- *    'enable search in address' admin setting ... and search control
- *    visibility is not changed for any other reason" — i.e.
- *    isTileCompanySearchActive() alone. Previously it hid on capture (the
- *    theory being that the notice sentence made a second, editable copy
- *    redundant) and briefly grew a decline-recovery carve-out
- *    (isCompanyRecoveryNeeded(), now deleted) to avoid trapping a declined
- *    buyer — found in testing to still leave the control gone, permanently,
- *    on the common approve path.
+ * Two independent rules define it:
  *
- *  - Bug B: a `.two-company-id-text` org-number LABEL now renders under the
- *    control once a company is captured (gated on isCompanyCaptured() &&
- *    isTileCompanySearchActive()), mirroring address-autocomplete.js's
- *    renderCompanyIdText()/`.two-company-id-text` (§5). This is NOT a
- *    reinstatement of the `.two-company-label` line §7 added and §7.3
- *    removed — that was a combined name+number line gated on the notice's
- *    own visibility, and it stays removed. The order-intent notice sentence
- *    is unaffected and still carries its own embedded "Name (number)" text
- *    independently of this label.
+ *  - the capture CONTROL (the field and whatever is mounted in it) is visible
+ *    exactly when the tile is where the page-level capture component has
+ *    chosen to mount — `isTileCompanyFieldVisible()` and nothing else. Capture
+ *    state and order-intent outcome do not affect it: gating it on capture made
+ *    the control disappear on the common approve path with nothing to bring it
+ *    back;
+ *  - a `.two-company-id-text` org-number LABEL renders under the control once a
+ *    company is captured, mirroring address-autocomplete.js's own label. It is
+ *    a separate surface from the order-intent notice, which carries its own
+ *    embedded "Name (number)" sentence.
  *
- * Four groups, and they are NOT the same kind of test. Be honest about which
- * is which before trusting a green run:
+ * Four groups, and they are NOT the same kind of test. Be honest about which is
+ * which before trusting a green run:
  *
  *  1. NO-INPUT PINS — 'the payment tile shows the number as an uneditable
- *     label, not a field'. These fail against the old `<input readonly>`

- *     because there is no `<input id="company_id">` left to satisfy either.

+ *     and against any future reinstatement of an editable NUMBER field, because
+ *     there is no `<input id="company_id">` left to satisfy either.
  *
- *  2. GATE PINS — the control's `visible:` binding
- *     (`isTileCompanySearchActive()` alone, post-2026-08-04) and the
- *     org-number label's (`isCompanyCaptured() && isTileCompanySearchActive()`)

+ *     on a coincidence.
  *
  *  3. WHAT-THE-BUYER-SEES PINS — 'what each capture mode puts in front of the
- *     buyer'. These do not restate the markup: they read the `text:` binding
- *     target out of the template, then evaluate it against a renderer driven

  *
  *  4. ACCEPTED-SOURCE REGRESSION PINS — most of 'an accepted organisation
- *     number still reaches the order'. These pass against the pre-change code
- *     too, because every accepted source already wrote the observable. They
- *     do NOT prove anything about the label. They exist because the

Subject: [PATCH 338/885] fix(TWO-25503): three defects found in adversarial
 review
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Country invalidation had exactly one trigger and it was the wrong one.
Only a `change` on an address-form select reached onCountryChanged(), and
it read the country through a shipping-first document scan. A saved
address in another country fired no event at all; a separate billing
country resolved to the unchanged shipping one and was dropped. Both left
a registry number standing under an address from a different registry,
which is the failure TWO-24867 exists to prevent. The quote now drives it
too, and the handler reads the select the buyer actually touched.

A tile replaced under an unchanged selector left the control bound to a
detached node. The node keeps its select2 data, so the control reports
itself bound and the mount refresh skipped — the buyer got a plain input
with no picker, permanently, because the selector never changes again.
The guard now compares node identity, which is the only thing that can
tell a replaced node from the one still on the page.

A sole trader with no registry number of their own inherited the number
of whatever company was captured before them, because the adoption write
was not authoritative. Their name went out attached to another company's
organisation number.

The lifecycle suite claimed to cover the second of these and did not: its
double reported itself bound independently of any node, so removing the
guard entirely left the suite green.

Subject: [PATCH 339/885] fix(TWO-25503): an authoritative write replaces both
 halves
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The previous commit stopped a numberless sole trader inheriting the
previous company's registry number, but left the mirror of it: the name
was written only when truthy, whatever the caller asked for, so a sole
trader with a number and no trading name of their own kept the earlier
company's NAME against their own number. The same mismatch, the other
field.

An authoritative write now replaces both halves, empty ones included —
which is what the callers already believed they were asking for.

+ * opt that control's in-dropdown button OUT, because on this surface the mode
+ * control is the only route to manual entry. The address-area mount, which
+ * has no mode control, keeps the button.
+ *
+ * TWO-25326 rebuild: the select2 wiring itself — including where
+ * `attachManualEntryButton`/`detachManualEntryButton` are actually called —
+ * moved out of this surface and into that one shared class. What is still
+ * specific to THIS surface, and still worth pinning here, is the glue: which
+ * hook it passes and what that hook does.
+ *
+ * Structural (source-grep) tests only: the surface's business logic here is
+ * a couple of lines of glue around calls the shared-model suite already
+ * proves correct in isolation, and jest-mocking gateway_method.js's full KO

- * TWO-25326 / TWO-25461 §1(a.3): which country the company search and the
- * sole-trader registry run against.
+ * TWO-25326, Fire Checkout: the payment tile's company search ran against the
+ * search API's own default country (US) whatever the buyer had actually
+ * selected in the address form — on Fire Checkout only, never on Luma or
+ * Amasty.
  *
- * The reported failure was Fire Checkout only: the search ran against the API's
- * own default country whatever the buyer had selected. It is a SOURCING gap
- * rather than a hardcoded country — the only feed was a customer-data section
- * written by `address-autocomplete.js` once `#shipping-new-address-form`
- * resolves, and a one-page checkout that supplies its own address markup
- * matches no such selector, so the country reaching the search URL was empty.
+ * Mechanism, and it is a SOURCING gap rather than a hardcoded country
+ * anywhere: the tile's picker asked `countryCode()`, a ko observable with
+ * exactly two feeds —
  *
- * Resolution order, and both halves matter:
+ *   1. the `countryCode` customer-data section, written ONLY by
+ *      address-autocomplete.js, and only once
+ *      `$.async('#shipping-new-address-form select[name="country_id"]')`
+ *      resolves;
+ *   2. updateAddress(), reading the country off the quote's PERSISTED
+ *      billing/shipping address.
  *
- *  1. the quote's BILLING address — the tile has no address fields of its own
- *     and captures as the invoice role, so a buyer shipping to one country and
- *     invoicing in another must search the one they invoice in;
- *  2. the buyer's live address-form `<select>`, via a priority list of
- *     selectors ending in a catch-all — the fallback for the window before the
- *     quote holds an address at all, which is the TWO-25326 state.
+ * Luma and Amasty render the core `#shipping-new-address-form` markup, so
+ * feed 1 fires on every country change and the observable is current before
+ * the buyer can search. A one-page checkout that supplies its own address
+ * markup matches neither that selector, nor — until the address is saved —
+ * has a persisted quote address to read; `fillCountryCode()` early-returns on
+ * an empty value, so the observable stayed at its `''` default and
+ * buildSearchAjaxOptions() put an EMPTY `country=` on the search URL.
+ *
+ * Fixed by sourcing the tile's search country from the buyer's actual
+ * `<select>` first (companySearch.currentAddressFormCountry(), a priority list
+ * of address-form selectors ending in a catch-all), with the observable kept
+ * as the fallback for the checkouts that genuinely have no address-form select
+ * — a saved address and a virtual cart.

+ * TWO-25503 — the three company-capture options as peers in ONE control.
  *
- * The chips are DOM, built by the component as a sibling of the field they act
- * on, the way WooCommerce (`syncSoleTraderChip`/`syncManualEntryButton`) and
- * PrestaShop (`renderChipSelection`) both build theirs. They are asserted here
- * against the real nodes the component produces, not against template markup:
- * a payment-tile template is destroyed on every totals change, which is the
- * whole reason chip ownership moved.
+ * The tile used to present a two-item tab bar (registered organisation / sole
+ * trader) and reach manual entry only through a separately worded button
+ * inside the search dropdown, so a buyer who wanted to type a name by hand
+ * had to open the picker and reject its results first. WooCommerce and
+ * PrestaShop both offer all three as peer options in one control; this pins
+ * Magento doing the same, each chip subject to its own gate.
  *
  * Mutation-resistance notes:
  *
- *  - selected state is read off the real class after a real mode transition,
- *    so hardcoding a selection on one chip fails;
- *  - each chip's gate is asserted by the node's own hidden state under both
- *    values of its gate, so making sole trader offerable in a country whose
- *    registry has none fails rather than reading as green;
- *  - the click assertions drive the real handler and read the resulting mode,
- *    never that a method exists. Emptying `manualEntryMode()` fails them.
+ *  - the template assertions read the mode control's OWN markup slice, and
+ *    each chip's selected state is asserted to be a binding against
+ *    `captureMode()`. A statically selected chip — which is exactly what the
+ *    old two-block markup had — fails, so re-hardcoding a selection cannot
+ *    pass;
+ *  - the behavioural assertions read real state after the real transition
+ *    (`companyId()`, the field's value, the recorded control calls), never
+ *    that a method exists. Emptying `manualEntryMode()` fails every one;
+ *  - the chip gating is asserted by nesting, so moving a chip out of its
+ *    `ko if` (making sole trader offerable in a country whose registry has no
+ *    sole traders) fails rather than reading as green.

- * TWO-25503 — the `postMessage` handshake the hosted signup finishes on, and
- * the one buyer lookup it is allowed to make.
+ * TWO-25461. Two buyer-identity lookups share one helper and must NOT share
+ * one rule.
  *
- * `/autofill/v1/buyer/current` answers with whatever buyer the Two cookie
- * identifies. Reading it BEFORE the buyer has authenticated is a cookie probe:
- * it would let a checkout adopt an identity nobody on this page proved they
- * hold. So the flow has exactly one caller — the ACCEPTED branch of the
- * handshake, after the hosted flow has verified the buyer server-side — and
- * that is pinned both behaviourally and in the source, because reinstating a
- * passive probe is invisible to every fixture that drives the handshake.
+ * `lookupSoleTrader()` is pre-auth: it reads whatever buyer the Two cookie
+ * happens to identify before the buyer has proved anything, so a
+ * buyer only counts when its email equals the one entered on the checkout
+ * form. That check is correct there and is pinned below as a regression guard.
  *
- * Post-authentication the email that authenticated IS the identity: the
- * checkout's own contact field has no say in it. Re-gating on a match there
- * discarded an authenticated buyer and left the company field permanently
- * blank with no route forward (TWO-25461).
+ * `popupMessageListener()`'s `ACCEPTED` branch is POST-AUTHENTICATION: the
+ * buyer has just completed verification server-side, and the email that
+ * authenticated is the identity. It used to re-run the same email-match
+ * comparison and, on a mismatch, take no branch at all — the buyer finished
+ * signup and got a permanently blank readonly/required company field with no
+ * route forward. `resolveBuyer(authenticated)` is what separates the two.
+ *
+ * `fetchBuyer()` is stubbed per test rather than driven through `fetch`: the
+ * behaviour under test is which buyer the two call sites ACCEPT, not how the
+ * buyer is transported. `getTokens()` is stubbed for the same reason.

- * TWO-25503 — the hosted sole-trader signup popup: how it is launched, what it
- * is launched with, and what happens to the checkout while it is open.
+ * TWO-25461 — the three defects in the sole-trader signup popup launch path.
  *
- * The flow is PAGE-LEVEL (`model/sole-trader.js`), constructed by the
- * company-capture component with that component as its host, so everything
- * below drives either the real flow against a stub host or the real component
- * with the real flow underneath it. Nothing here reaches through a payment
- * renderer, which no longer participates.
- *
- * Mutation-resistance notes:
- *
- *  - the mint is asserted to have happened with the popup count still zero and
- *    no chip clicked, so moving it into the click handler fails rather than
- *    reading as green;
- *  - the click assertion runs in the SAME TICK as the click, with no await
- *    between: an `await` introduced anywhere on the launch path leaves the
- *    popup unopened at the assertion, which is exactly what a popup blocker
- *    would do;
- *  - the country param is read back off the URL under a host whose own
- *    `countryCode()` throws, so sourcing it from the DOM-fed value fails;
- *  - the busy flag and the abandon callback are read after driving the real
- *    watcher tick, never by asserting a method exists.
+ * 1. The popup opened 610px wide, narrower than the hosted signup flow's own
+ *    minimum layout width (700), which clipped it.
+ * 2. The note's overlay element bound a click to `hideIframe()`, a method that
+ *    exists on nothing. It was the last remnant of a removed in-page iframe
+ *    modal (no `.iframe-parent` markup survives, and nothing adds the `.show`
+ *    class its stylesheet needs), so the element was permanently invisible and
+ *    the broken binding only latent — an overlay stylesheet making it visible
+ *    was all it took to turn a click into a TypeError. The element is gone.
+ * 3. The "popup not ready" branch offered the fallback link before the signup
+ *    tokens were minted, so clicking it built
+ *    `…?businessToken=&autofillToken=…` — a URL the hosted flow rejects.

- * TWO-25461 §7 — re-signing up as a different sole trader.
- *
- * Two routes reach the same place: the payment tile's "Select a different sole
- * trader" link, and re-clicking the sole-trader chip once one is already
- * adopted. Both must carry `autoselect=false`, or the hosted flow silently
- * re-picks the registration the buyer is trying to replace and hands back the
- * identity already on screen — a dead end with no visible cause.
- *
- * The tile no longer owns the flow. It delegates to the page-level
- * company-capture component, which is what survives the payment-method list
- * being rebuilt on every totals change, so the link's own case below is a
- * delegation check and the behaviour is driven through the real component.
+ * TWO-25461 §7 — the two UX gaps left after the popup-launch bugfixes
+ * (PR #343): the "select a different sole trader" link/autoselect param,
+ * and the in-flight spinner for the chip lookup's round trip.

+ *    redundant) and briefly grew a decline-recovery carve-out
+ *    (isCompanyRecoveryNeeded(), now deleted) to avoid trapping a declined

- *  - the capture CONTROL (the field and whatever is mounted in it) is visible
- *    exactly when the tile is where the page-level capture component has
- *    chosen to mount — `isTileCompanyFieldVisible()` and nothing else. Capture
- *    state and order-intent outcome do not affect it: gating it on capture made
- *    the control disappear on the common approve path with nothing to bring it
- *    back;
- *  - a `.two-company-id-text` org-number LABEL renders under the control once a
- *    company is captured, mirroring address-autocomplete.js's own label. It is
- *    a separate surface from the order-intent notice, which carries its own
- *    embedded "Name (number)" sentence.
+ *  - Bug B: a `.two-company-id-text` org-number LABEL now renders under the
+ *    control once a company is captured (gated on isCompanyCaptured() &&
+ *    isTileCompanySearchActive()), mirroring address-autocomplete.js's
+ *    renderCompanyIdText()/`.two-company-id-text` (§5). This is NOT a
+ *    reinstatement of the `.two-company-label` line §7 added and §7.3
+ *    removed — that was a combined name+number line gated on the notice's
+ *    own visibility, and it stays removed. The order-intent notice sentence
+ *    is unaffected and still carries its own embedded "Name (number)" text

+ * Four groups, and they are NOT the same kind of test. Be honest about which
+ * is which before trusting a green run:
  *
  *  1. NO-INPUT PINS — 'the payment tile shows the number as an uneditable
- *     label, not a field'. These fail against the old `<input readonly>` shape

+ *     shape and against any future reinstatement of an editable NUMBER field,
+ *     because there is no `<input id="company_id">` left to satisfy either.
  *
- *  2. GATE PINS — the control's `visible:` binding and the org-number label's
- *     are each pinned to their exact shape, so a drift to some other predicate
- *     — or to an always-true stub — fails the string match rather than passing
- *     on a coincidence.
+ *  2. GATE PINS — the control's `visible:` binding
+ *     (`isTileCompanySearchActive()` alone, post-2026-08-04) and the
+ *     org-number label's (`isCompanyCaptured() && isTileCompanySearchActive()`)
+ *     are pinned separately, each to its exact shape, so a drift to some

+ *     rather than passing on a coincidence.
  *
  *  3. WHAT-THE-BUYER-SEES PINS — 'what each capture mode puts in front of the
- *     buyer'. These do not restate the markup: they read the binding target out
- *     of the template and evaluate it against a renderer driven through the

  *
  *  4. ACCEPTED-SOURCE REGRESSION PINS — most of 'an accepted organisation
- *     number still reaches the order'. They exist because the observable is the
- *     ONLY carrier — the label has no `name` and submits nothing — so a change
- *     that breaks a writer path loses the number outright rather than falling
- *     back to a field, and the sole-trader route is the one most likely to
- *     break silently, its value being minted rather than picked.

-/**
- * TWO-25503: the company-capture component — Magento's counterpart to
- * WooCommerce's `class TwoCompanySearch` and PrestaShop's `TwoCompanySearch.js`.
- *
- * ONE component per checkout page, owning BOTH the mode chips and the search
- * mount, exactly as those two do. It is constructed once, by the headless
- * `view/company-search-boot.js` uiComponent, and outlives every payment-tile
- * render: Luma, Amasty and Fire Checkout all re-create payment renderers on
- * every totals change, and a component living inside one had its chips, its
- * mount and its popup handle destroyed underneath the buyer mid-flow.
- *
- * Owns:
- *  - the three chips (Registered company / Sole trader / Enter manually),
- *    built in JS as a sibling of the field they act on, the way both sibling
- *    platforms build theirs;
- *  - the one `CompanySearchControl` and WHERE it is mounted, re-pointing it
- *    between the address step and the payment tile as the checkout changes
- *    shape;
- *  - the billing country the search runs against, and the sole-trader
- *    availability answer for it.
- *
- * Does NOT own: the identity it captures (company-identity.js), the
- * sole-trader flow (sole-trader.js), or the transport and address write-back
- * (company-search.js). Same split as WooCommerce's
- * `twoincCompanyCapture` / `twoincSoleTrader` / search internals.

+     * and buildSearchAjaxOptions() put an EMPTY `country=` on the search
+     * URL, which the API answers under its own default.
+     *
+     * The real fix is the THIRD feed added by watchAddressFormCountry()
+     * below, which keeps `countryCode()` current on any checkout. This
+     * getter is the belt-and-braces on top of it: the observable FIRST,

+     * i.e. only in the window before anything has resolved a country at all,
+     * which is exactly the state that produced the bug.
+     *
+     * That order matters and is not interchangeable. DOM-first was tried and
+     * rejected in adversarial review: core renders `#shipping-new-address-form`
+     * inside the HIDDEN new-address modal for a customer who has saved

+     * placeOrderIntent() already read, so this is one resolution reused
+     * rather than a fourth mirror. Accepted cost: while the buyer is editing
+     * the billing form and has not applied it, the quote holds the previous
+     * country.

- * handshake landed on a listener that no longer recognised the window.
+ * Owns the whole flow end to end: minting the delegation/autofill token pair,
+ * the passive buyer lookup on the Two cookie and its per-email dedup, the
+ * hosted signup popup (including the country parameter the popup's identity

- * popup and the watcher that notices the buyer closing it, and the

+ * renderer. Everything shared with the rest of the checkout is reached
+ * through it and never duplicated here: the brand config, the buyer's email,
+ * the company identity observables and their writers, the mode observables
+ * the chips drive, and the error surface. Everything private to the flow —

+            TWO-25503: ONE control offering the three company-capture options
+            as peers, matching WooCommerce and PrestaShop. It replaces a
+            two-item tab bar (registered / sole trader) plus a separately
+            worded "My company is not on the list" button inside the search
+            dropdown, which made manual entry reachable only by opening the
+            picker and rejecting its results.
+
+            Deviation from WC/PS, forced rather than chosen: both siblings
+            build the chip group INSIDE the open picker, as a sibling of the
+            results list, because their picker stays alive across every mode.
+            Magento's sole-trader and manual modes both tear the select2
+            widget down (enterSoleTraderUi/clearCompany), so chips living in
+            the dropdown would be unreachable from exactly the two modes that
+            need a way back. They therefore stay in this persistent control.
+
+            Which chips render is per-option, not per-control:
+              - registered is unconditional — it is also the way OUT of the
+                other two, and that has to work on a checkout whose search
+                control lives in the address area;
+              - sole trader follows showModeTab (the billing country's
+                registry supports SOLE_TRADER);
+              - manual entry follows showManualEntryChip(): it acts on the
+                tile's own company-name field, so where the address area owns
+                the search control instead it belongs to that mount and its
+                own in-dropdown button; and with the address-area setting off
+                it is not offered at all, because no address-step lookup then
+                exists to supply the company number the method requires.

+                    TWO-25326, 2026-08-04 ruling (supersedes the §7/§7.1
+                    capture-state and decline-recovery gating that used to
+                    live in this comment — Doug's exact words: "the search
+                    control ... is controlled ONLY by the state of the
+                    'enable search in address' admin setting: if true,
+                    search control is rendered inside the address block,
+                    otherwise is rendered inside the payment tile — and
+                    search control visibility is not changed for any other
+                    reason").
+
+                    So this field's visibility depends on ONE thing —
+                    isTileCompanySearchActive(), the live read of that single
+                    admin setting (plus the saved-address/virtual-cart
+                    fallback documented on that method in gateway_method.js,
+                    which is the SAME condition, not a second one). It no
+                    longer depends on isCompanyCaptured() or on any
+                    order-intent outcome: the control stays visible after a
+                    company is picked, whether the subsequent order-intent
+                    call approves, declines, or errors. The org-number label
+                    below (not the notice sentence) is now the one thing that
+                    changes on capture.
+
+                    The previous behaviour hid this field once
+                    isCompanyCaptured() went true, on the theory that the
+                    order-intent notice sentence made an editable, visible
+                    control redundant — and only re-showed it on a decline,
+                    via isCompanyRecoveryNeeded(), to avoid a dead end for a
+                    buyer with no other route to pick a different company.
+                    Doug found this INCORRECT in live testing on 2026-08-04:
+                    the control was disappearing when a company was picked
+                    and, on the common path (order intent approves), never
+                    coming back — with nothing marking that as intentional
+                    from the buyer's side. This ruling removes that coupling
+                    entirely rather than patching it again.
+
+                    `visible:`, not `if:`, for the same reason as before:
+                    it keeps the node in the DOM so the select2 binding, its
+                    MutationObserver rebinding and the sole-trader write path
+                    all keep working untouched; `if:` would destroy and
+                    rebuild the node under them.
+
+                    Hiding (when isTileCompanySearchActive() is false) also
+                    takes this `required` input out of jQuery Validation's
+                    way — `elements()` skips hidden fields, and that state is
+                    exactly the one where the buyer has the address-area
+                    control instead.

+                            modes it must stay writable: company search replaces
+                            this node with its own select2 chrome (so the buyer
+                            never types here anyway), and manual entry tears the

+                            by hand. A static `readonly` here would brick manual
+                            entry outright.

+                            gateway_method.js. This input is `required`, and
+                            jQuery Validation enforces that on a `[readonly]`
+                            field (it skips only `:disabled`), so any state
+                            where the field can be both empty and locked is a

+                            See TWO-25288.
+
+                            `required` is likewise BOUND, not static, to
+                            `isTileCompanySearchActive()` — the same condition
+                            the wrapper's `visible:` binding above uses. `visible`
+                            only sets `display:none` on the wrapper; it does not
+                            touch this input's `required` attribute, and native
+                            HTML5 constraint validation still blocks form

Subject: [PATCH 342/885] fix(TWO-25503): register one $.async observer per
 selector
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

`bind()` registered a fresh MutationObserver on every call and nothing
ever disconnected one, so observers accumulated for the life of the page.
Each observer's callback rebuilds select2, which mutates the DOM, which
re-fires every observer registered so far — on a checkout that re-binds
per totals change that compounds until the renderer stops responding.

One observer per selector is enough: it already re-fires when the node is
replaced, which is the case re-binding exists for. A caller asking to
re-bind while one is watching gets the widget rebuilt immediately rather
than waiting for the next mutation.

The harness's `$.async` stub ran the callback once and never again, so
stacking could not be expressed and no test could have caught this. It
now records registrations and replays them the way a mutation does.
Against the unfixed control the new suite fails five of eight, reporting
one observer per bind and ten re-initialisations for a single mutation.

From 2bbfa1f6fbd862659d7d7b9c962b63cb911df0b4 Mon Sep 17 00:00:00 2001
From: Douglas Lindsay <dlindsay@two.inc>
Date: Wed, 26 Aug 2026 16:45:08 +0100
Subject: [PATCH 343/885] refactor(TWO-25503): page-level company-capture
 component
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Re-lands the component reverted in #368, on top of the observer-leak fix
in #370, with the two changes that revert made necessary.

`isMountLive()` is gone. It existed because the control reported itself
bound off a node that could be detached, so a replaced tile left the
buyer a dead input. With one `$.async` observer per selector guaranteed,
that observer re-initialises on the replacement itself and the case is
handled a layer down. The guard is what re-bound per totals change and
stacked observers until the renderer stopped responding — it produced
three of the five defects the previous attempt's review found, so it is
removed rather than patched again.

`onCountryChanged()` returns early without a brand config. The boot hook
calls it on every address and totals change, on every checkout, and
`start()` bails leaving no flow to tell and no registry to ask — so on a
merchant with no Two-family method it made a registry call it had no
business making and then dereferenced a null flow.

Both are mutation-checked: without the guard the country change throws
`Cannot read properties of null (reading 'forgetAdoptions')`, and the
tile-replacement case now pins that re-binding is the control's job.

+ * The reported failure was Fire Checkout only: the search ran against the API's
+ * own default country whatever the buyer had selected. It is a SOURCING gap
+ * rather than a hardcoded country — the only feed was a customer-data section
+ * written by `address-autocomplete.js` once `#shipping-new-address-form`
+ * resolves, and a one-page checkout that supplies its own address markup
+ * matches no such selector, so the country reaching the search URL was empty.
  *
- *   1. the `countryCode` customer-data section, written ONLY by
- *      address-autocomplete.js, and only once
- *      `$.async('#shipping-new-address-form select[name="country_id"]')`
- *      resolves;
- *   2. updateAddress(), reading the country off the quote's PERSISTED
- *      billing/shipping address.
+ * Resolution order, and both halves matter:
  *
- * Luma and Amasty render the core `#shipping-new-address-form` markup, so
- * feed 1 fires on every country change and the observable is current before
- * the buyer can search. A one-page checkout that supplies its own address
- * markup matches neither that selector, nor — until the address is saved —
- * has a persisted quote address to read; `fillCountryCode()` early-returns on
- * an empty value, so the observable stayed at its `''` default and
- * buildSearchAjaxOptions() put an EMPTY `country=` on the search URL.
- *
- * Fixed by sourcing the tile's search country from the buyer's actual
- * `<select>` first (companySearch.currentAddressFormCountry(), a priority list
- * of address-form selectors ending in a catch-all), with the observable kept
- * as the fallback for the checkouts that genuinely have no address-form select
- * — a saved address and a virtual cart.
+ *  1. the quote's BILLING address — the tile has no address fields of its own
+ *     and captures as the invoice role, so a buyer shipping to one country and
+ *     invoicing in another must search the one they invoice in;
+ *  2. the buyer's live address-form `<select>`, via a priority list of
+ *     selectors ending in a catch-all — the fallback for the window before the
+ *     quote holds an address at all, which is the TWO-25326 state.

+ * TWO-25503 — the three company-capture options as peers in ONE control, owned
+ * by the company-capture component.
  *
- * The tile used to present a two-item tab bar (registered organisation / sole
- * trader) and reach manual entry only through a separately worded button
- * inside the search dropdown, so a buyer who wanted to type a name by hand
- * had to open the picker and reject its results first. WooCommerce and
- * PrestaShop both offer all three as peer options in one control; this pins
- * Magento doing the same, each chip subject to its own gate.
+ * The chips are DOM, built by the component as a sibling of the field they act
+ * on, the way WooCommerce (`syncSoleTraderChip`/`syncManualEntryButton`) and
+ * PrestaShop (`renderChipSelection`) both build theirs. They are asserted here
+ * against the real nodes the component produces, not against template markup:
+ * a payment-tile template is destroyed on every totals change, which is the
+ * whole reason chip ownership moved.
  *
  * Mutation-resistance notes:
  *
- *  - the template assertions read the mode control's OWN markup slice, and
- *    each chip's selected state is asserted to be a binding against
- *    `captureMode()`. A statically selected chip — which is exactly what the
- *    old two-block markup had — fails, so re-hardcoding a selection cannot
- *    pass;
- *  - the behavioural assertions read real state after the real transition
- *    (`companyId()`, the field's value, the recorded control calls), never
- *    that a method exists. Emptying `manualEntryMode()` fails every one;
- *  - the chip gating is asserted by nesting, so moving a chip out of its
- *    `ko if` (making sole trader offerable in a country whose registry has no
- *    sole traders) fails rather than reading as green.
+ *  - selected state is read off the real class after a real mode transition,
+ *    so hardcoding a selection on one chip fails;
+ *  - each chip's gate is asserted by the node's own hidden state under both
+ *    values of its gate, so making sole trader offerable in a country whose
+ *    registry has none fails rather than reading as green;
+ *  - the click assertions drive the real handler and read the resulting mode,
+ *    never that a method exists. Emptying `manualEntryMode()` fails them.

- * TWO-25461. Two buyer-identity lookups share one helper and must NOT share
- * one rule.
+ * TWO-25503 — the `postMessage` handshake the hosted signup finishes on, and
+ * the one buyer lookup it is allowed to make.
  *
- * `lookupSoleTrader()` is pre-auth: it reads whatever buyer the Two cookie
- * happens to identify before the buyer has proved anything, so a
- * buyer only counts when its email equals the one entered on the checkout
- * form. That check is correct there and is pinned below as a regression guard.
+ * `/autofill/v1/buyer/current` answers with whatever buyer the Two cookie
+ * identifies. Reading it BEFORE the buyer has authenticated is a cookie probe:
+ * it would let a checkout adopt an identity nobody on this page proved they
+ * hold. So the flow has exactly one caller — the ACCEPTED branch of the
+ * handshake, after the hosted flow has verified the buyer server-side — and
+ * that is pinned both behaviourally and in the source, because reinstating a
+ * passive probe is invisible to every fixture that drives the handshake.
  *
- * `popupMessageListener()`'s `ACCEPTED` branch is POST-AUTHENTICATION: the
- * buyer has just completed verification server-side, and the email that
- * authenticated is the identity. It used to re-run the same email-match
- * comparison and, on a mismatch, take no branch at all — the buyer finished
- * signup and got a permanently blank readonly/required company field with no
- * route forward. `resolveBuyer(authenticated)` is what separates the two.
- *
- * `fetchBuyer()` is stubbed per test rather than driven through `fetch`: the
- * behaviour under test is which buyer the two call sites ACCEPT, not how the
- * buyer is transported. `getTokens()` is stubbed for the same reason.
+ * Post-authentication the email that authenticated IS the identity: the
+ * checkout's own contact field has no say in it. Re-gating on a match there
+ * discarded an authenticated buyer and left the company field permanently
+ * blank with no route forward (TWO-25461).

- * TWO-25461 — the three defects in the sole-trader signup popup launch path.
+ * TWO-25503 — the hosted sole-trader signup popup: how it is launched, what it
+ * is launched with, and what happens to the checkout while it is open.
  *
- * 1. The popup opened 610px wide, narrower than the hosted signup flow's own
- *    minimum layout width (700), which clipped it.
- * 2. The note's overlay element bound a click to `hideIframe()`, a method that
- *    exists on nothing. It was the last remnant of a removed in-page iframe
- *    modal (no `.iframe-parent` markup survives, and nothing adds the `.show`
- *    class its stylesheet needs), so the element was permanently invisible and
- *    the broken binding only latent — an overlay stylesheet making it visible
- *    was all it took to turn a click into a TypeError. The element is gone.
- * 3. The "popup not ready" branch offered the fallback link before the signup
- *    tokens were minted, so clicking it built
- *    `…?businessToken=&autofillToken=…` — a URL the hosted flow rejects.
+ * The flow is PAGE-LEVEL (`model/sole-trader.js`), constructed by the
+ * company-capture component with that component as its host, so everything
+ * below drives either the real flow against a stub host or the real component
+ * with the real flow underneath it. Nothing here reaches through a payment
+ * renderer, which no longer participates.
+ *
+ * Mutation-resistance notes:
+ *
+ *  - the mint is asserted to have happened with the popup count still zero and
+ *    no chip clicked, so moving it into the click handler fails rather than
+ *    reading as green;
+ *  - the click assertion runs in the SAME TICK as the click, with no await
+ *    between: an `await` introduced anywhere on the launch path leaves the
+ *    popup unopened at the assertion, which is exactly what a popup blocker
+ *    would do;
+ *  - the country param is read back off the URL under a host whose own
+ *    `countryCode()` throws, so sourcing it from the DOM-fed value fails;
+ *  - the busy flag and the abandon callback are read after driving the real
+ *    watcher tick, never by asserting a method exists.

- * TWO-25461 §7 — the two UX gaps left after the popup-launch bugfixes
- * (PR #343): the "select a different sole trader" link/autoselect param,
- * and the in-flight spinner for the chip lookup's round trip.
+ * TWO-25461 §7 — re-signing up as a different sole trader.
+ *
+ * Two routes reach the same place: the payment tile's "Select a different sole
+ * trader" link, and re-clicking the sole-trader chip once one is already
+ * adopted. Both must carry `autoselect=false`, or the hosted flow silently
+ * re-picks the registration the buyer is trying to replace and hands back the
+ * identity already on screen — a dead end with no visible cause.
+ *
+ * The tile no longer owns the flow. It delegates to the page-level
+ * company-capture component, which is what survives the payment-method list
+ * being rebuilt on every totals change, so the link's own case below is a
+ * delegation check and the behaviour is driven through the real component.

- * The payment tile's company display, as the TWO-25326 2026-08-04 ruling
- * now defines it. Two things changed from the 2026-08-03 (§7.3) shape this
- * file used to pin, and they are independent:
+ * The payment tile's company display.
  *
- *  - Bug A: the capture CONTROL's (the field + picker) visibility is no
- *    longer gated on isCompanyCaptured() or on any order-intent outcome at
- *    all. Doug's exact words: it "is controlled ONLY by the state of the
- *    'enable search in address' admin setting ... and search control
- *    visibility is not changed for any other reason" — i.e.
- *    isTileCompanySearchActive() alone. Previously it hid on capture (the
- *    theory being that the notice sentence made a second, editable copy
- *    redundant) and briefly grew a decline-recovery carve-out
- *    (isCompanyRecoveryNeeded(), now deleted) to avoid trapping a declined
- *    buyer — found in testing to still leave the control gone, permanently,
- *    on the common approve path.
+ * Two independent rules define it:
  *
- *  - Bug B: a `.two-company-id-text` org-number LABEL now renders under the
- *    control once a company is captured (gated on isCompanyCaptured() &&
- *    isTileCompanySearchActive()), mirroring address-autocomplete.js's
- *    renderCompanyIdText()/`.two-company-id-text` (§5). This is NOT a
- *    reinstatement of the `.two-company-label` line §7 added and §7.3
- *    removed — that was a combined name+number line gated on the notice's
- *    own visibility, and it stays removed. The order-intent notice sentence
- *    is unaffected and still carries its own embedded "Name (number)" text
- *    independently of this label.
+ *  - the capture CONTROL (the field and whatever is mounted in it) is visible
+ *    exactly when the tile is where the page-level capture component has
+ *    chosen to mount — `isTileCompanyFieldVisible()` and nothing else. Capture
+ *    state and order-intent outcome do not affect it: gating it on capture made
+ *    the control disappear on the common approve path with nothing to bring it
+ *    back;
+ *  - a `.two-company-id-text` org-number LABEL renders under the control once a
+ *    company is captured, mirroring address-autocomplete.js's own label. It is
+ *    a separate surface from the order-intent notice, which carries its own
+ *    embedded "Name (number)" sentence.
  *
- * Four groups, and they are NOT the same kind of test. Be honest about which
- * is which before trusting a green run:
+ * Four groups, and they are NOT the same kind of test. Be honest about which is

  *
  *  1. NO-INPUT PINS — 'the payment tile shows the number as an uneditable

  *
- *  2. GATE PINS — the control's `visible:` binding
- *     (`isTileCompanySearchActive()` alone, post-2026-08-04) and the
- *     org-number label's (`isCompanyCaptured() && isTileCompanySearchActive()`)

-     * one-page checkouts (Fire Checkout) only.
-     *
-     * Why only there: `countryCode()` had exactly two feeds — the
-     * `countryCode` customer-data section, written ONLY by
-     * address-autocomplete.js's toggleCompanyVisibility()/onCountryChanged()
-     * once `$.async('#shipping-new-address-form select[name="country_id"]')`
-     * resolves, and updateAddress(), which reads the country off the quote's
-     * PERSISTED billing/shipping address. On Luma and Amasty the first feed
-     * fires on every country change, so the observable is current before the
-     * buyer can search. A one-page checkout supplying its own address markup
-     * matches neither that selector nor — until the address is saved — has a
-     * persisted quote address to read, so `fillCountryCode()`'s
-     * `if (!countryCode) return;` left the observable at its `''` default,
-     * and buildSearchAjaxOptions() put an EMPTY `country=` on the search
-     * URL, which the API answers under its own default.
-     *
-     * The real fix is the THIRD feed added by watchAddressFormCountry()
-     * below, which keeps `countryCode()` current on any checkout. This
-     * getter is the belt-and-braces on top of it: the observable FIRST,
-     * because it is the authoritative value (quote-derived, and now
-     * DOM-driven too), and a direct DOM read only when it is still empty —
-     * i.e. only in the window before anything has resolved a country at all,
-     * which is exactly the state that produced the bug.
-     *
-     * That order matters and is not interchangeable. DOM-first was tried and
-     * rejected in adversarial review: core renders `#shipping-new-address-form`
-     * inside the HIDDEN new-address modal for a customer who has saved
-     * addresses, and renders one billing-address form PER payment method, so
-     * a DOM-first read could let an untouched form's STORE DEFAULT country
-     * beat a correct quote-derived one — reintroducing the same class of bug
-     * on the platforms that worked.
-     *
-     * TWO-25461 §1(a.3): the tile has no address fields of its own, so its
-     * country is the BILLING/INVOICE-role address's — and every feed below is
-     * shipping-biased in some state, so a buyer shipping to one country and
-     * invoicing in another could search the wrong registry.
-     *
-     * `quote.billingAddress()` rather than a live read of the billing form:
-     * billing is Magento's non-default form, and §1(a.3) says its value comes
-     * from the sync mechanism (core's own same-as-shipping copy into the
-     * quote). It is also the source getAutofillData(), getData() and
-     * placeOrderIntent() already read, so this is one resolution reused
-     * rather than a fourth mirror. Accepted cost: while the buyer is editing
-     * the billing form and has not applied it, the quote holds the previous
-     * country.
-     *
-     * This getter feeds the SEARCH. Sole-trader availability and the

-            TWO-25503: ONE control offering the three company-capture options
-            as peers, matching WooCommerce and PrestaShop. It replaces a
-            two-item tab bar (registered / sole trader) plus a separately
-            worded "My company is not on the list" button inside the search
-            dropdown, which made manual entry reachable only by opening the
-            picker and rejecting its results.
-
-            Deviation from WC/PS, forced rather than chosen: both siblings
-            build the chip group INSIDE the open picker, as a sibling of the
-            results list, because their picker stays alive across every mode.
-            Magento's sole-trader and manual modes both tear the select2
-            widget down (enterSoleTraderUi/clearCompany), so chips living in
-            the dropdown would be unreachable from exactly the two modes that
-            need a way back. They therefore stay in this persistent control.
-
-            Which chips render is per-option, not per-control:
-              - registered is unconditional — it is also the way OUT of the
-                other two, and that has to work on a checkout whose search
-                control lives in the address area;
-              - sole trader follows showModeTab (the billing country's
-                registry supports SOLE_TRADER);
-              - manual entry follows showManualEntryChip(): it acts on the
-                tile's own company-name field, so where the address area owns
-                the search control instead it belongs to that mount and its
-                own in-dropdown button; and with the address-area setting off
-                it is not offered at all, because no address-step lookup then
-                exists to supply the company number the method requires.

-                    TWO-25326, 2026-08-04 ruling (supersedes the §7/§7.1
-                    capture-state and decline-recovery gating that used to
-                    live in this comment — Doug's exact words: "the search
-                    control ... is controlled ONLY by the state of the
-                    'enable search in address' admin setting: if true,
-                    search control is rendered inside the address block,
-                    otherwise is rendered inside the payment tile — and
-                    search control visibility is not changed for any other
-                    reason").
-
-                    So this field's visibility depends on ONE thing —
-                    isTileCompanySearchActive(), the live read of that single
-                    admin setting (plus the saved-address/virtual-cart
-                    fallback documented on that method in gateway_method.js,
-                    which is the SAME condition, not a second one). It no
-                    longer depends on isCompanyCaptured() or on any
-                    order-intent outcome: the control stays visible after a
-                    company is picked, whether the subsequent order-intent
-                    call approves, declines, or errors. The org-number label
-                    below (not the notice sentence) is now the one thing that
-                    changes on capture.
-
-                    The previous behaviour hid this field once
-                    isCompanyCaptured() went true, on the theory that the
-                    order-intent notice sentence made an editable, visible
-                    control redundant — and only re-showed it on a decline,
-                    via isCompanyRecoveryNeeded(), to avoid a dead end for a
-                    buyer with no other route to pick a different company.
-                    Doug found this INCORRECT in live testing on 2026-08-04:
-                    the control was disappearing when a company was picked
-                    and, on the common path (order intent approves), never
-                    coming back — with nothing marking that as intentional
-                    from the buyer's side. This ruling removes that coupling
-                    entirely rather than patching it again.
-
-                    `visible:`, not `if:`, for the same reason as before:
-                    it keeps the node in the DOM so the select2 binding, its
-                    MutationObserver rebinding and the sole-trader write path
-                    all keep working untouched; `if:` would destroy and
-                    rebuild the node under them.
-
-                    Hiding (when isTileCompanySearchActive() is false) also
-                    takes this `required` input out of jQuery Validation's

Subject: [PATCH 344/885] TWO-25503 mount company search when its host node
 appears

start() runs from the checkout sidebar, before the address form exists and
before the quote carries a billing address, so the mount selector and country
both resolved empty and nothing re-drove them. Watch for either candidate host
via $.async and mount when it arrives.

The harness now installs the $.async simulation over real jQuery too, so suites
using real DOM do not have to know a module waits for a node.

Subject: [PATCH 346/885] TWO-25503 resolve the country once a form can answer
 for it

Measured on staging: the company input lands 44ms before the country select,
so the mount watcher asks for a country nothing can answer yet and sole-trader
availability early-returns. The select then arrives already holding the default,
so the `change` that would ask again never fires and the sole-trader chip stays
hidden for every buyer who keeps their default country.

Watch for the select itself and re-resolve through countryCode(), so an
appearing billing form cannot impose its own default over the quote.

The harness delivered every registration on fireAll(), letting one watcher stand
in for another and hiding a missing one; it now delivers a node once, as an
observer does.

Subject: [PATCH 347/885] TWO-25503: rebuild company capture as one unified
 popover
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Replace the select2 picker with a self-owned panel anchored to the company
field, holding the query input, the results and the mode chips as one control.
select2 appends its dropdown to <body> and rewrites it on every open, so the
chips could only ever be a sibling it drew over — which is what hid them
exactly when the buyer opened the thing that offers them.

Matches PrestaShop's TwoCompanySearch structure.

- * TWO-25326: the single class that owns the company-search picker's full
- * lifecycle end to end — select2 construction, dropdown open/close wiring,
- * the manual-entry button, the "Search for company" return link, and
- * open-on-type — built on top of the shared, mount-agnostic primitives in
- * `company-search.js` (the search request, result mapping, address
- * write-back, and the in-field chrome helpers).
- *
- * The select2 wiring, configured entirely through the constructor options
- * below. One instance exists per checkout page, built and owned by
- * `company-capture-component.js`, which decides where it is mounted and
- * re-points it with `bind()` as the checkout changes shape — the address
- * step and the payment tile are two candidate hosts for one widget, never
- * two widgets.

-     * @param {object} options
-     * @param {string} options.fieldSelector jQuery selector for the
-     *        company-name input this control binds to. Re-resolved via
-     *        `$.async` on every bind() call, so a node replaced by a
-     *        checkout re-render is picked up automatically.
-     * @param {object} options.config brand config subtree — needs
-     *        `checkoutApiUrl`, `companySearchLimit`, `isAddressSearchEnabled`.
-     * @param {function(): (string|undefined)} [options.getCountryCode]
-     *        returns the current ISO country code (any case), read fresh on
-     *        every search request.
-     * @param {function(object, object)} [options.onSelect] called with
-     *        (selectedItem, $field) when the buyer picks a company from the
-     *        dropdown. `selectedItem` is select2's result item
-     *        (`{id, text, html, companyId, lookupId}` — see
-     *        company-search.js's `processResults`).
-     * @param {boolean} [options.manualEntryEnabled=true] build the
-     *        "My company is not on the list" button inside the dropdown. The
-     *        payment tile turns this OFF (TWO-25503): manual entry is a peer
-     *        chip in its mode control, and a second, differently worded route
-     *        to the same mode is what that control replaced.
-     * @param {function} [options.onReturnToSearch] called when the "Search
-     *        for company" link puts the buyer back in search mode, for a
-     *        mount that tracks the active mode itself.
-     * @param {function(object, object)} [options.onManualEntryActivated]
-     *        called with ($field, bindToken) once the buyer has actually
-     *        activated the "My company is not on the list" button. Owns
-     *        whatever "manual entry" means for this mount — the two call
-     *        sites deliberately differ here (address step: convert the
-     *        field to a plain typeable text input; payment tile: tear the
-     *        widget down entirely and show the "Search for company" link).
-     * @param {function(object)} [options.onBound] called with ($field) once
-     *        per bind(), after every handler is wired — the hook for
-     *        mount-specific paint that has to run after binding (placeholder
-     *        text, a pre-filled selection's rendered text, …).
-     * @param {function(): string} [options.templateSelectionFallback] text
-     *        shown in the closed combobox when select2 has no `text` to
-     *        render for the current selection.
-     * @param {string} [options.searchForCompanyText] label for the
-     *        "Search for company" return link.
-     * @param {string} [options.searchForCompanyId] `id` attribute to give
-     *        the "Search for company" link and to resolve it by. Omit when
-     *        multiple instances of this control can exist on one page (the
-     *        payment tile, pushed once per brand) — the link is then found
-     *        and scoped by CONTAINER instead, exactly as the class already
-     *        scopes every other per-bind lookup.

+/**
+ * TWO-25503: the company-capture popover — one anchored panel that owns the
+ * query field, the result list AND the mode chips, matching PrestaShop's
+ * `TwoCompanySearch`. There is no separate chip row: opening the control shows
+ * the buyer one box containing every route it offers.
+ *
+ * This replaces the select2 picker. select2 could never satisfy that
+ * requirement: it appends its dropdown to `<body>` and rewrites the contents on
+ * every open, so anything of ours placed beside the field was a sibling the
+ * dropdown drew over rather than a part of the control. The chips were
+ * therefore hidden precisely when the buyer opened the thing that offers them.
+ *
+ * DOM ORDER IS THE DESIGN, not an implementation detail. Everything lives
+ * inside the same `.two-company-field-wrap` as the company-name input, in this
+ * order:
+ *
+ *   input[company] -> query field -> results host -> mode chips
+ *
+ * so the browser's own tab order walks the control the way it reads, and the
+ * chips stay reachable without tabbing through up to 50 results. The panel is
+ * `hidden` while closed, so none of it is a tab stop until the buyer opens it.
+ *
+ * Owns: the panel DOM, open/close, the query field, result rendering and
+ * keyboard navigation, and the chips' markup and selected state.
+ * Does NOT own: which chip means what (company-capture-component.js), the
+ * search request or address write-back (company-search.js).

From c3ffbe788effd382ac308373c6f0a0772f6f3932 Mon Sep 17 00:00:00 2001
From: Doug Lindsay <dlindsay@two.inc>
Date: Wed, 26 Aug 2026 22:56:52 +0100
Subject: [PATCH 348/885] TWO-25503: move the tests onto the popover, and fix
 the blocked-signup note
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The suites were written against select2's own DOM and its transport contract;
they now assert the same guarantees against the panel and searchCompanies().

Also fixes a real bug the chip move introduced: the blocked-popup fallback
note anchored itself after the chips, which now live inside the popover that
entering sole-trader mode closes — so the buyer's only route forward rendered
inside something they could not see. Anchored outside the popover instead.

- * #30.x.15. The manual-entry affordance was previously a real `<li
- * role="option">` living INSIDE the select2 results list, on the premise
- * that inheriting select2's own keyboard model was the only way to keep it
- * reachable. Live testing after that shipped found the tradeoff was worse
- * than the defect it fixed:
+ * #30.x.15. The manual-entry affordance has been a row inside the results
+ * list, and then a button beside it; TWO-25503 makes it one of the mode chips
+ * inside the popover itself. Each move was driven by the same two failures:
  *
- *  - `.select2-results__options` is exactly the element select2 clips and
- *    scrolls, so the row was only visible once the buyer scrolled past
+ *  - anything living inside the results list is inside the element the picker
+ *    clips and scrolls, so it was only visible once the buyer scrolled past
  *    however many real results came back, and reaching it by keyboard meant
  *    arrowing down through every one of them;
- *  - Enter worked (it closes over select2's own `select2:selecting`
- *    dispatch), but Space did not: select2's core only special-cases
- *    Enter/Up/Down/Escape on the search field's keydown, so an unhandled
- *    Space fell through to its native default of typing a literal space
- *    character into the search box.
+ *  - anything living outside the popover is a sibling of the company field,
+ *    which the open popover draws over — so the route out of search mode was
+ *    hidden exactly while the buyer was in search mode.
  *
- * This file pins the replacement: a real `<button>`, a SIBLING of the
- * results list rather than a row inside it, which fixes both by
- * construction — native Tab-adjacent focus, native Enter/Space activation,
- * and a position outside select2's own scroll/clip area so it is always
- * visible once the search threshold is met.
+ * The chip fixes both by construction: a real `<button>`, a descendant of the
+ * panel, placed AFTER the results host so the browser's own tab order reaches
+ * it without walking the results, and painted inside the panel so opening the
+ * panel cannot cover it.
  *
  * Mutation-resistance notes:
- *  - the model tests run against REAL jsdom nodes through a small
- *    jQuery-lite double, so `length`, class lists, attributes and sibling
- *    position are the document's answers, not a stub's;
- *  - the threshold is injected DELIBERATELY WRONG (5), so asserting against
- *    a surviving literal 3 cannot pass;
- *  - translation is asserted on the msgid, since `$t` resolves to identity
- *    here;
+ *  - the chip assertions run against the REAL panel over REAL jsdom nodes, so
+ *    tag name, containment and document order are the document's answers;
+ *  - translation is asserted on the msgid, since `$t` resolves to identity here;
  *  - the mode-transition tests read identity state and real DOM attributes

- *    implementation that opened a dropdown nothing could type into.
- *  - The select2 double is DOM-backed: `select2('open')` really attaches a
- *    dropdown containing a real `<input class="select2-search__field">` and
- *    really marks the container open, so the production
- *    `document.querySelector('.select2-search__field').focus()` has to run
- *    against a live node for the focus assertion to pass.
- *  - `select2('open')` on a destroyed/absent widget THROWS in the double, as

- *  - Every case first drives the real journey (mount → manual entry → return)

Subject: [PATCH 349/885] TWO-25503: fix the lifecycle and input holes review
 round 1 found

- one $.async observer per selector EVER, not per selector transition, and the
  observer for an abandoned mount no longer drags the panel back to it
- a re-render no longer wipes a manually typed company name or re-arms the
  field as a search trigger while manual entry owns it
- leaving a mount unwraps it, so a second wrapper cannot clone the
  sole-trader fallback note
- manual entry writes through to Knockout, so the quote stops carrying the
  company the buyer just abandoned
- IME composition and paste reach the query field: seeding moved from keydown,
  which reports no printable key for either, to input
- combobox semantics moved onto the field the keyboard actually reaches
- closing aborts the search still on the wire
- "the search is down" is styled apart from "your company is not here" again
- per-panel result-row ids, so aria-activedescendant cannot resolve into a
  sibling panel
- destroy() is final against observers it cannot disconnect

Subject: [PATCH 350/885] TWO-25503: cover the panel's own contract, and stop
 saying the hint twice
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The open/close/teardown/keyboard contract had no suite of its own — the
neighbouring ones each reach through the panel at something else — so a dozen
guarantees were passing vacuously. Each new case is pinned by a mutation that
turns the suite red.

The too-short hint now renders once: the query field's placeholder carries it
for an untouched field, and the message line takes over only when the buyer is
actually short of the threshold.

e2e drives the popover rather than the deleted select2 widget.

Subject: [PATCH 351/885] TWO-25503: five fixes from the first hands-on pass
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

- the too-short hint reads "Enter 3 or more characters", matching PrestaShop
- the signup popup comes down when focus returns to the CHECKOUT page, and
  only then: focus leaving for a mail client to fetch an OTP leaves it up.
  Clicking the Sole trader chip is the one exception and raises it instead
- manual entry renders the "Search for company" link again, below the field
  and right-aligned — without it manual entry is a dead end
- clicking the company field lands the caret in the query box, rather than
  waiting for the first keystroke: the mousedown's own default action was
  taking focus straight back out
- the query row shows in registered-company mode alone; a sole trader is
  enrolled through the hosted signup and a manual name is typed into the
  company field, so a query box answers for neither

Subject: [PATCH 352/885] TWO-25503: keep the popover open behind the signup
 popup
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The chips have to stay on screen while the buyer is in the hosted signup,
or the only route back to the Sole trader chip is the company field — and
clicking that reads as "focus is back on checkout", which takes the signup
down a moment before they can reach the chip.

The popup now comes down only when focus returns to checkout AND settles
outside this control, so a click landing inside the popover is the buyer
reaching for the signup rather than away from it.

Subject: [PATCH 353/885] TWO-25503: focus the query field when returning to
 search on an open panel

open() returned early when the panel was already up, which is exactly the
state coming back from sole-trader mode leaves: the popover stays open
behind the signup popup with the query row hidden, so the buyer landed on a
search box nothing had put the caret in.

It now re-syncs and re-focuses whether or not the panel was already open,
with the sync ordered first so the query row is showing before the caret is
asked to go there.

Subject: [PATCH 355/885] TWO-25503: extract the company popover into a
 framework-free module

The Hyva extension carries its own parallel popover implementation, and that
duplication is why the two checkouts keep drifting apart. It cannot reuse this
one while the file depends on jQuery, mage/translate and a company-search
module that reaches Magento_Checkout's Knockout quote.

Pure refactor: same DOM, same order, same copy, same behaviour. Everything
platform-shaped is now injected - `search` (the six-member transport, which
Magento passes as the company-search module verbatim), `translate` and
`observe` - and the UMD tail lets a host with no RequireJS load the same
deployed file as a plain script.

Test changes are delivery-mechanism only, no assertion touched: jQuery's
.trigger() walks its own handler store and calls elem[type](), which does not
exist for `input` or `mousedown`, so those call sites now dispatch the same
event natively. The teardown suite counts document listeners by intercepting
addEventListener rather than reading jQuery's namespace store.

Subject: [PATCH 356/885] TWO-25503: unbind a discarded chip's listeners with
 the chip

jQuery's `.empty()` dropped the handler data for everything it removed; the
vanilla port recorded only exact-target matches, so every chip rebuild - one
per totals change on a re-rendering checkout - left an entry behind for the
page's lifetime.

Subject: [PATCH 357/885] TWO-25461: source the search country from the
 selector adjacent to the mount

The search country now follows the country selector in the form the control is
mounted in. The payment tile has no such selector, so there the quote's billing
address still decides.

Subject: [PATCH 359/885] TWO-25461: drive the tile mount's country from the
 invoice address form
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The payment tile now reads the country selector in the form holding the buyer's
invoice address — the billing form where core rendered one, else the shipping
form. The quote's billing country is the last resort, for a checkout with no
address form carrying a country selector at all.

Subject: [PATCH 363/885] Do not render the mode-chip row when only one chip is
 visible

TWO-40. On a non-sole-trader country with company search out of the
address step, "Registered company" is the only surviving chip - the mode
the buyer is already in - so the row offers no choice.

Counted in the shared panel, where the hidden class is applied, so a chip
that is built and then hidden does not keep the row alive. The row is
hidden rather than removed: the panel keeps its three children in order.

Subject: [PATCH 364/885] fix(company-search): keep the popover open when focus
 is DROPPED, not moved
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

TWO-25503. The deferred close read only "is focus still inside the panel",
which is false the moment a mode change hides the row holding the caret —
sole-trader mode does exactly that, and the popover shut behind the signup
popup. Focus landing on the body is not the buyer leaving.

That also covers the scrollbar drag the pointer guard was built for, so the
guard goes with it: forty lines whose only remaining job was putting the
caret back afterwards, through an unconditional focus() on a row that is
display:none in two of the three capture modes.

The sole-trader case in company-search-return-to-search.test.js asserted
synchronously and so passed against a deferred close either way.

Subject: [PATCH 365/885] TWO-25503: report a morphed-away panel as unbound,
 and rebuild cleanly

A host that re-renders by morphing its server markup over the live DOM
deletes the wrapper the panel builds and keeps the field, so isBound()
answered true for a control that was no longer on the page and nothing
could tell that it had to rebuild.

+ * TWO-25503 — surviving a host that re-renders by MORPHING server markup over
+ * the live DOM.
+ *
+ * The panel builds a `span.two-company-field-wrap` around the company field and
+ * appends itself there. That wrapper is in no host's server markup, so a morph
+ * deletes it — panel, chips and every attribute the panel wrote — while KEEPING
+ * the field node. The field is then bare and clicking it does nothing until the
+ * page is reloaded.
+ *
+ * Two guarantees make a host able to recover from that, and neither can be
+ * asserted by driving the panel's happy path:
+ *  - `isBound()` has to ANSWER FALSE, so the host has something to poll. A
+ *    field-only check answers true, because the field is exactly what the morph
+ *    keeps;
+ *  - rebuilding must not accumulate a `document` listener per rebuild, or a
+ *    checkout that re-renders on every keystroke leaks one per render.
+ *
+ * Mutation-resistance notes:
+ *  - the morph is applied to the REAL DOM the panel built, in the order a morph
+ *    applies it, rather than simulated by nulling the panel's own fields — a
+ *    check that reads state instead of the document would still pass;
+ *  - the listener case counts live `document` listeners by intercepting
+ *    add/removeEventListener, so an unbind that records but does not remove
+ *    fails;
+ *  - each morph case starts from a DIFFERENT live state (closed, open, manual
+ *    entry just exited), because the three checkout actions that trigger this
+ *    reach the morph from those three states.

Subject: [PATCH 366/885] TWO-25503: size the popover's rows and chips for a
 field-width panel

The panel is as wide as the company field, which is half a column on a
three-column checkout. Rows are ellipsised on one line rather than wrapping
onto four with a horizontal scrollbar, the chips take PrestaShop's sizing so
two share a row, and the matched substring stops rendering as a yellow
highlighter.

Subject: [PATCH 368/885] TWO-25503: release the detached panel's listeners
 when rebuilding
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

A host that discards the wrapper but keeps the field re-binds through
_attach's rebinding path, which skips _releaseWrap(), so the listeners on
the panel that went with the wrapper were never taken back — six per
re-render, each pinning the detached subtree it names.

Subject: [PATCH 370/885] TWO-25461: never source the country from the hidden
 new-address modal

For a buyer with saved addresses core renders the shipping form — company
field, country select and all — inside a hidden modal holding store
defaults. Sourcing the country from the selector adjacent to the mount let
that untouched default beat the quote's billing country, on both the
address mount and the tile mount.

Subject: [PATCH 371/885] Translate the no-company-number refusal messages

TWO-25326: the checkout submit block was untranslated in every shipped
locale, so the buyer met it in English. Pins both buyer-facing strings of
this gate against silent i18n rot, and covers an internally-minted
identifier in the server guard's accepted-input table.

Subject: [PATCH 374/885] TWO-25503: stop the rebuild loop that closes the
 company popover

A checkout that posts on the company field's change event morphs away the
runtime wrapper in the response, and the rebuild that follows repainted the
same value and announced it again. After the first re-render the cycle never
settled: the popover was torn down every few seconds, so it would not stay
open for the buyer to type into.

setDisplayText() now announces the field only when it actually changed it.

Subject: [PATCH 375/885] TWO-25503: one company-capture controller, shared by
 Luma and Hyva

The capture controller, the identity it writes and the sole-trader flow are
now framework-free with UMD tails, exactly as company-search-panel.js already
was, so the Hyva checkout loads these same files instead of reimplementing
them. Everything platform-shaped arrives through a host contract.

model/company-capture.js is Luma's half of that contract: jQuery, the quote
model, mage/url and the message list reduced to the functions the controller
asks for.

Subject: [PATCH 376/885] TWO-25503: pin the host contract, and the manual
 path's name write

A host missing any member of the contract is refused at construction, so a
partial one fails at the boundary rather than deep inside a buyer's flow.

commitManualCompany() writes the name through the accessor: `write()` reads an
empty name as "nothing to write", which left the previous company's name on
screen after the buyer emptied the field.

Subject: [PATCH 377/885] TWO-25503: write() notifies only on a real change

Every other writer skips a no-op; write() did not, so a restore that re-wrote
the same pair on each re-render woke every subscriber.

Subject: [PATCH 378/885] TWO-25503: no raw NUL byte in the identity source
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The no-op check compared a joined key built on a literal U+0000, which made the
file binary to git — invisible to `git diff`, to `git grep`, and so to the
pre-push leak gate. Compares the three fields directly instead.

Subject: [PATCH 379/885] Drop the company-field watermark and clip the length
 hint

The "Enter company name to search" watermark carried no information the
buyer needed. The panel's length hint is wider than the query field in
some layouts, so it now clips with an ellipsis and hovers in full.

Subject: [PATCH 381/885] Key the return-link sweep to the panel that rendered
 it

Two panels on one page shared one class-wide sweep, so either entering or
leaving manual entry on one deleted the other's only route back to search.
The sweep stays document-wide, to collect a link a host re-render cloned
away from the panel's own reference, but now matches only its own id.

refreshMount() returned on an empty selector without clearing _boundSelector, so
adjacentCountry() went on answering for a form that had gone and nothing
self-healed.

 cleaning

The instance-keyed sweep could not collect a link an earlier bind left on
the same field. Scoped to the current field's wrapper instead, which covers
that orphan and still leaves a second panel's link on another field alone.

Subject: [PATCH 387/885] TWO-25503: fixes from review round 4

- sole-trader.js took `translate` off the host, which is not part of the host
  contract; a conforming host without it threw inside the signup error path.
- The address step's queued publish now checks it is still the current watcher:
  the ko.computed it replaced cancelled its pending notification on dispose, a
  bare setTimeout does not.

Subject: [PATCH 388/885] Remove the unused allowed_countries brand descriptor
 field

The field was parsed and exposed but never read. Country availability is
merchant-scoped and runtime-resolved, so a build-time brand-overlay
allow-list is the wrong home for it and leaves two country mechanisms in
one repo.

Subject: [PATCH 391/885] feat: hide the payment method outside the merchant's
 buyer-country allowlist

TWO-40: the merchant record carries an optional list of supported buyer
countries. Judge the quote's billing country (falling back to shipping,
then the store default) against it, as a second gate ANDed with core's own
admin-configured country restriction.

Subject: [PATCH 394/885] feat: firewall token header on outbound API calls

Merchants whose network traffic passes through a firewall appliance can
be required to tag egress with a token. Adds the admin field, sends it as
X-WAF-TOKEN on every server-side call, and moves the registry and
order-intent calls out of the browser so they pick it up too.

Subject: [PATCH 395/885] chore: bump version to 2.3.0

The proxied checkout routes added on this branch are a hard dependency for
the Hyva extension, which needs a composer floor no earlier release can
satisfy.

Subject: [PATCH 396/885] fix: rate-limit the anonymous checkout routes and
 harden the proxy envelope

Adds a cache-backed per-IP ceiling to every anonymous webapi route, makes the
proxy envelope read the real upstream status instead of inferring failure from
body key names, refuses an order intent whose merchant cannot be verified
rather than sending a null identity, and covers the browser-exposure gate on
the firewall token.

Subject: [PATCH 397/885] fix: key the anonymous-route ceiling on the
 connecting peer

Review round on the new anonymous webapi routes. Stock Magento trusts
X-Forwarded-For with no proxy allow-list, so the limiter's caller key was
client-supplied: a rotated header bought a fresh bucket per request and a
never-colliding cache entry with it. Keyed on the TCP peer instead.

Also: registry calls are attributed to the server-resolved merchant rather
than relying on a browser parameter this PR removed; refusals answer through
the envelope contract the browser reads, with a 429 handled as a wait rather
than a decline; anonymous callers no longer receive transport-failure text;
payloads are size-capped; and the ceilings on order-intent and token minting
have headroom for an office behind one NAT address.

Subject: [PATCH 398/885] fix: resolve the rate-limit caller through trusted

Keying the ceiling on REMOTE_ADDR alone collapses every buyer behind a
reverse proxy, CDN or load balancer into one bucket, turning a per-caller
limit into a store-wide one.

- * What the ceiling does and does not guarantee: load→compare→save over
- * CacheInterface is not atomic and the interface offers no atomic
- * increment, so concurrent requests can read the same count and all pass.
- * It bounds SUSTAINED cost from one caller, not the exact number of
- * requests admitted in any instant.

- * Backed by CacheInterface, the same store ApiKeyStatus memoises through —
- * so a multi-node store shares counters exactly as far as it shares that
- * cache backend, and no new infrastructure is introduced.

Subject: [PATCH 399/885] fix: refuse a malformed trusted-proxy rule instead of
 trusting everything

A non-numeric CIDR bit-suffix cast to 0 and matched every address of
that family, so one typo in the trusted-proxy list retired the checkout
rate limit entirely. Rejected before the cast, refused at save time, and
the refusal diagnostics no longer flood the log or advise disabling the
ceiling against what may be an attack.

From: Douglas Lindsay <dlindsay@two.inc>

Subject: [PATCH 400/885] fix: refuse a zero-width trusted-proxy rule and read
 refusals by share
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

A /0 suffix passes the numeric guard and then matches every address of
its family before any address byte is compared, so a match-everything
entry made every caller its own trusted proxy — free to name its
identity through the forwarding header and take a fresh bucket per
request. The admin save path shared the guard, so the entry stored
cleanly rather than being refused.

The refusal log read one caller from there being a single address
rather than from the share one holds, so a single incidental buyer
flipped a dominant caller's window to "ordinary load" and its advice to
turn the ceiling off. Reports also committed to the window's first five
refusals and never revised; they now land on a geometric ladder, which
keeps a flood's log cost logarithmic while the last report describes
the traffic as it finally stood.

Subject: [PATCH 401/885] fix: scrub upstream failure bodies and scope API
 calls to their store

Round 5 review follow-ups.

Anonymous webapi routes no longer relay upstream non-2xx bodies; the real
body is logged server-side and the caller gets the generic refusal already
used for the transport-failure case. Order intent refuses list-shaped
payloads, company lookup requires a non-empty query and an ISO-2 country.

Adapter calls that had an order or quote in hand now pass its store id, so
cron, observer and admin-initiated requests resolve the token at the right
scope instead of the default one.

The address-lookup failure notice moves to the tile notice box on the
identity bus so a later successful pick retires it, and a 429 on the
company-by-id route parks the shared backoff window like the search route
already did.

From 694546ae530ad43fd917edeebc85bf030ef7ac98 Mon Sep 17 00:00:00 2001

Subject: [PATCH 402/885] fix: keep the address-lookup notice out of the
 order-intent box

The credit check normally answers after the company-address lookup, so
clearOrderIntentNotices() was destroying an address failure the buyer
still had to act on. The address notice now has its own observable and
its own box, and withdrawing it empties that box.

Also adds a generation token to the address lookup, so picking company B
while A is in flight can no longer write A's address under B.

Subject: [PATCH 403/885] fix: relay buyer-actionable 4xx detail, resolve the
 store, signal the proxy gap

The envelope guard rewrote every non-2xx upstream body to a generic
refusal, which made four order-intent validation branches dead code and
told a buyer with a bad org number the service was down. A 4xx now
relays error_code/error_message/error_details/error_json and nothing
else; 5xx and transport failures stay generic.

The proxy routes, SurchargeCalculator and SupportedCompanyTypes now
resolve the store from the quote rather than calling upstream at default
scope, so a multi-store install spends the right API key.

Rate limiting stays on by default, so a store that upgrades behind a CDN
now gets an admin notice pointing at the trusted-proxy list, and the
setting's help text states the consequence of leaving it empty.

RateLimiter still admits the request when the cache backend is dead, but
says so once per request instead of silently.

Subject: [PATCH 404/885] TWO-25503: wire commitManualCompany, test
 signupPrefill
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

commitManualCompany() was dead code — manualEntryMode() now watches
the released field's input events and calls it, so an edited name
genuinely drops a stale vouched registry number.

signupPrefill() had no test coverage; added shape + guest-email
fallback cases, mutation-proved.

Subject: [PATCH 406/885] fix: PHP 8.1 trait-const fatal + IPv6 /64 rate-limit
 bucketing

RELAYED_4XX_FIELDS was a trait const, which requires PHP 8.2; composer.json
still declares >=8.1, and the fatal crashed every anonymous webapi route
under the declared floor. Moved it to a trait method instead.

RateLimiter::caller() keyed its bucket cache on the raw resolved IP, so a
single routed IPv6 /64 could mint unlimited buckets. Masks IPv6 callers to
their /64 (IPv4 unmasked) at the one chokepoint where identity becomes a
cache key.

Subject: [PATCH 407/885] fix(company-capture): manual-edit watcher dedupes per
 selector, not per lifetime

Round 4's fix gated _watchManualEdits() on one boolean for the component's
whole life, but the mount re-points between the address field and the tile
field as the cart flips virtual. Once bound on one selector, manual edits on
the other were never observed again, silently dropping a typed company name.
Dedupe per selector instead, matching company-search-panel.js's pattern.

Subject: [PATCH 409/885] fix(company-search): let the popover overhang a
 narrow field instead of truncating

The panel's width was anchored exactly to the company field via left:0/right:0,
so on Hyva's payment tile (roughly a third of a three-column row) every result
name was clipped to a few characters. min-width lets a narrow field's panel
overhang it, matching PrestaShop's 320px cap; a wide field (Luma) is unaffected.

Subject: [PATCH 410/885] fix(company-search): widen popover min-width, drop
 wrong-repo class name
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Comment named a PrestaShop repo class and cited its 320px cap as
precedent — that rule is a max-width on jQuery UI's dropdown solving
the opposite problem (too wide), not a min-width floor. Removed both.

Bumped 320px to 480px: live check against a 10-result set ("international")
at Hyva's tile width cut ellipsised rows from 5/10 to 2/10, no viewport
overflow. Two of the longest legal names still ellipsise at any of these
widths.

Subject: [PATCH 411/885] fix: clamp company popover max-width to viewport

min-width:480px could overhang a phone-width (<512px) viewport with
no bound. max-width: min(480px, 100vw-32px) keeps the floor for
wide screens but guarantees the panel never exceeds the screen.

Subject: [PATCH 412/885] fix: min-width always beats max-width, popover clamp
 was a no-op
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

CSS2.1 §10.4: min-width wins over max-width. `min-width: 480px` next
to `max-width: min(480px, calc(100vw - 32px))` made the viewport clamp
dead below a 512px viewport — panel stayed 480px wide, same overflow
round 4 claimed to fix. Single clamped `width` replaces both; no
competing min-width. Test asserted the raw min-width value existed
rather than any resolved-width interaction — replaced with cases
computing the resolved width at 375/414/480/512/768px.

Subject: [PATCH 413/885] refactor: rename the confirm-check admin toggle to
 'token'

Retires the previous wording of the skip-confirm-check admin toggle in
favour of 'token' across the config path, admin field, interface method
and tests, with a data patch carrying stored values across every scope.

Subject: [PATCH 414/885] fix: replace vacuous per-viewport width tests with a
 real formula pin

The 5 parametrized "resolved width" cases regex-matched the declared
width string and separately recomputed the same clamp arithmetic in
JS, so they passed regardless of the actual CSS (confirmed: jsdom's
getComputedStyle returns '' for any declaration using calc()/min(),
so no per-viewport pixel value can be asserted here at all). Replaced
with a single test pinning the exact declared formula, which a
mutation to either the min-width guard or the formula itself now
genuinely fails.

Subject: [PATCH 415/885] fix: type-hint ApiKey's resourceCollection param so
 di:compile can resolve it
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

An untyped $resourceCollection param broke setup:di:compile's inherited
object-binding resolution for resource/resourceCollection (normally
inherited from Value/Encrypted), compiling it to a broken literal array
instead of the resolved Proxy — fataling on every instantiation and
blanking the whole admin config section this field lives in.

Subject: [PATCH 416/885] fix: add missing firewall/rate-limit fields to
 brand-form admin template
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

PR #394 added firewall_token, firewall_token_browser, trusted_proxies
and disable_rate_limit to etc/adminhtml/system.xml but not to
brand_form_template.xml, whose merge with system.xml silently drops
any field the template doesn't already declare — invisible in the
admin UI on every environment. Adds the 4 fields in the same
group/style as their system.xml counterparts and extends
SynthesiseBrandAdminFormProviderTokenTest to assert they survive
synthesis.

Subject: [PATCH 417/885] refactor: move Trusted proxies and browser
 firewall-token toggle to Diagnostics
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Both fields configure the rate-limit/firewall-token subsystem covered by
Diagnostics > Admin Controls, not general checkout setup. Moves them out of
General in both system.xml and brand_form_template.xml (whose deep-merge with
system.xml drops any field it doesn't declare in the same shape — see PR
#398), rewrites their help text, and updates the two places that pointed
merchants at the old location: TrustedProxiesMessage's admin-notification
link and RateLimiter's rate-limit-refusal hint. Removes the now-stale i18n
comment translations for the retired English text; new translations aren't
expected yet.

firewall_token (the base enable/toggle) stays in General.

 label casing
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

api_key_check ("API key is valid") rendered below Firewall token; moves
its sortOrder to sit directly after api_key, ahead of firewall_token, in
both system.xml and brand_form_template.xml. firewall_token's label was
the one Title Case outlier among General/Diagnostics field labels on this
form (all others are sentence case) — retitled to "Firewall token".

Subject: [PATCH 420/885] Cache term-fee pricing quotes across requests, scoped
 to cart state
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

SurchargeCalculator::calculate() re-called checkout-api's pricing
endpoint on every checkout interaction even when nothing relevant had
changed — its cache was request-scoped only. Cache the quote in
CacheInterface keyed on the exact outgoing request body (cart total,
currency, buyer country, term, surcharge config), following
RecordProvider's fetch-and-cache pattern: only a successful quote is
persisted, and CACHE_LIFETIME is a backstop for drift the request body
can't see (e.g. an FX-rate shift), not the primary invalidation.

Subject: [PATCH 421/885] Align admin settings with cross-plugin conventions
 (TWO-25386)

Sentence-case captions, live inline API-key verification instead of a
separate check button, fold Company Lookup into Checkout Fields, drop
14-day from the shipped payment-terms default, remove the no-op skip
confirm-order token check toggle, and resolve the shipping tax
fallback through a configurable Product Tax Class (tax-rules engine)
ahead of the deprecated flat-rate field, matching prestashop-plugin
and woocommerce-plugin.

From: Douglas Lindsay <dlindsay@two.inc>

Subject: [PATCH 422/885] feat(TWO-25554): billing-panel company search
 alongside shipping
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Splits the single page-level company-capture component into two
independent instances — shipping and a new billing address panel —
plus a resolver that decides which one's capture is the buyer's actual
paying-as company: billing wins once it is a distinct address and
presents a company number, falling back to shipping otherwise.

company-identity.js becomes an instance factory rather than a
singleton; company-search.js's address-lookup in-flight guard is
scoped per calling panel so two simultaneous mounts never abort or
supersede each other; gateway_method.js re-resolves and supersedes any
in-flight order-intent check live when the resolved company changes,
including a plain "same as shipping" checkbox toggle with no fresh
pick at all.

Subject: [PATCH 423/885] fix(TWO-25554): scope shipping's writes and billing's
 mount to survive Amasty
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Amasty's one-step checkout renders every payment method's billing
fieldset in the DOM (hidden) from page load, unlike Luma which only
inserts it once "same as shipping" is unchecked. Two consequences:

- shipping's applyCompanyAddress/applyBuyerAddress used
  companySearch.billingRoleFormRoot(), which wins on presence alone
  regardless of visibility — so on Amasty it always resolved to the
  (hidden) billing form instead of shipping's own, misdirecting
  shipping's picks into billing's fields.
- the billing panel's mount-appeared watcher ($.async) fires once,
  the instant its selector's node exists — which on Amasty is before
  the buyer ever reveals it, so the one-shot check runs while hidden
  and nothing re-drives it afterwards; the billing company-search
  widget never mounts at all.

Scopes shipping's writes to its own form root (falling back to
billingRoleFormRoot() only for the tile-mount case that always
needed it), and wires a refreshMount() re-check into the "same as
shipping" checkbox toggle for both panels.

Subject: [PATCH 424/885] fix(TWO-25554): scope company-field display to its
 own panel, not just address writes

Two page-level company writers predate the shipping/billing panel split and
still assumed one company per page, so each panel's pick painted the other
panel's company field: the shipping step's company/organization mirror onto
every billing address form, and the quote's billing address feeding the
shipping identity through the payment renderer. Both now stop at the billing
panel's own mount, the same boundary shippingWriteRoot() draws for address
writes.

+ *
+ * Both defects this pins were live on a checkout rendering both panels, and
+ * neither is about the address sub-fields `shippingWriteRoot()` already
+ * scopes — they are about the value of the company field ITSELF, written by

+ *  - the shipping step mirrors its own company/organization onto every
+ *    billing address form (`setCompanyData()`), so a shipping pick painted
+ *    the billing panel's field;
+ *  - the quote's billing address feeds the SHIPPING identity
+ *    (`updateBillingAddress()` → `fillCompanyData()`), which the shipping
+ *    step then paints into its own field, so a billing pick painted the
+ *    shipping panel's field.
+ *
+ * Asserted on the two FIELDS in a real document, with the real

Subject: [PATCH 425/885] fix(TWO-25554): decide billing-company ownership from
 the panel's capture, not a live DOM query
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

A billing company still reached the shipping identity on Fire Checkout. The
gate asked one question — does the billing panel hold a live mount — and asked
it of the DOM at the moment of the write. Fire re-renders its payment area from
the same change that pushes the pick into the quote, so the quote's own
notification can land while the billing fieldset is detached and the query
answers no; the companyData section outlives the page load entirely, so it can
arrive with no billing form on the page at all. Both are now answered by the
billing panel's own capture, which is module state and survives every
re-render. The mount question stays where it was right: the mirror, which runs
while nothing is re-rendering.

Subject: [PATCH 426/885] fix(TWO-25554): start the order-intent check for the
 resolved company without writing the shipping identity

The renderer reacts to the resolved company changing by starting a fresh
order-intent check, and did so through fillCompanyData(), whose other half
writes the SHIPPING panel's identity. The resolved identity is a live mirror of
whichever panel wins, so every billing-only pick wrote billing's name and
number back into the shipping panel, which the address step then displayed as
the buyer's own shipping-step pick. The write ran before the
isOrderIntentEnabled check, so it happened whether or not intents were on.

Splitting the check out of fillCompanyData() leaves each concern with its own
source: the check follows the resolved company, an identity write stays the
shipping panel's own business.

Subject: [PATCH 427/885] fix(TWO-25554): scope every capture-panel operation
 to its own panel

The shipping and billing company-capture panels shared page-wide
operations and module state, so an action in one reached the other. Each
panel now supplies its own address root, its own country listener, its
own signup prefill and its own rate-limit scope, and the gates that
suppressed the cross-panel writes are gone with the writes.

Company and organisation number are no longer mirrored between the two
addresses at all; the address prefill itself is unchanged, and a billing
capture pins the billing address against it.

 /**
- * TWO-25554, Fire Checkout regression: a company the BILLING panel captured
- * must never become the shipping identity's, however it reaches the payment
- * renderer.
+ * TWO-25554: the quote's BILLING address never speaks for the shipping
+ * identity, whatever the DOM looks like at the moment it notifies.
  *
- * The first fix for this asked one question — does the billing panel hold a
- * live mount at its own field — and asked it of the DOM at the moment of the
- * write. That is sound for the mirror, which runs while nothing is
- * re-rendering, and it held on Amasty's static one-step layout in both
- * directions. It does not hold for a company arriving through the quote or
- * through `companyData`:
+ * Earlier fixes asked whether the billing panel held a live mount, or whether
+ * the arriving name matched billing's own capture. Both were questions about
+ * the instant of the write, and neither survived Fire Checkout re-rendering
+ * its payment area from the same `change` that pushes the pick into the quote.
+ * The provenance of the address is the whole answer: a billing address is the
+ * billing panel's, mounted or not.
  *
- *  - Fire Checkout re-renders its payment area from the same `change` that
- *    pushes the pick into the quote, so the quote's notification can land
- *    while the billing fieldset is detached — mounted in every sense the
- *    buyer can see, and the query answers no;
- *  - `companyData` is a localStorage section that outlives the page load, so
- *    a company can arrive from it before any billing form exists.
- *
- * Both are modelled here by taking the billing field away AFTER the pick,
- * which is what either one looks like at the one moment that matters.
+ * The billing field is taken away AFTER the pick below, which is what a
+ * re-render — or a `companyData` row outliving the page — looks like at the
+ * one moment that matters.

Subject: [PATCH 432/885] fix(TWO-25554): scope every address read and write to
 the panel that owns the form

Deletes the page-wide paths rather than gating them: `applyAddress()`,
`revertAutofilledAddress()`, `lookupCompanyAddress()` and
`currentAddressFormCountry()` all require the calling panel's own form and
refuse without one, and the full-address shipping-to-billing mirror,
`billingRoleFormRoot()` and the company/organisation propagation are gone. A
tile-mounted shipping panel has no write root at all.

Subject: [PATCH 433/885] fix(TWO-25554): bind the payment tile to the panel
 mounted there

The tile's company input, its readonly state, its spinner and its number label
now read the identity of the panel actually mounted at the tile, so a keystroke
there cannot reach another panel and needs no guard. The quote's billing
address seeds the BILLING panel's own identity instead of being relayed into
the shipping one.

Subject: [PATCH 434/885] test(TWO-25554): pin panel independence against the
 real cross-panel paths

The independence fixture now boots the real address step and the real payment
renderer, so the propagation paths the old gates covered are actually
exercised, and covers each panel reacting to its own country switch, the
retraction staying inside the form that asked for it, the tile binding and the
quote's billing address seeding the billing panel.

Subject: [PATCH 436/885] feat: enforce the buyer-country allowlist tri-state
 at submit
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The merchant record's allowlist field is now read as three states rather
than collapsed to one fail-open outcome: absent means unrestricted,
present-but-empty/null/malformed admits no country, and a populated list
is an allowlist. An unresolvable record stays unrestricted.

Adds the two submit-time gates the plugin lacked — one in authorize(),
one on the order-intent route — so a hidden method cannot be placed, and
logs every rejection with the state that caused it.

Subject: [PATCH 439/885] fix(TWO-25554): delete the shipping-to-billing
 country write outright
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The country was the last field one panel wrote into the other's form, and
its `change` ran the billing panel's own onCountryChanged() — clearing the
buyer's billing capture. The address mirror it belonged to is already gone,
so the pin, the per-address records and the rendered baselines go with it.

Subject: [PATCH 440/885] fix(TWO-25554): arbitrate the tile mount, and route
 the billing seed by role
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The payment tile is one field for one company, so the shipping panel takes
it only while the billing panel has no mount of its own — otherwise the
buyer faced a second visible, required company field the resolver ignores.

The quote's billing address seeds the panel that owns the billing ROLE:
the billing panel while billing is distinct, the shipping panel otherwise,
which is the only capture the resolver reads there.

Subject: [PATCH 441/885] test(TWO-25554): pin the independence of the two
 panels' forms and mounts

Covers the couplings the earlier rounds left untested: a shipping country
switch firing no event on the billing country select, the tile mount
collision, and the virtual-cart billing seed. Row descriptions are compared
rather than passed to toBe(), which Jest ignores.

Subject: [PATCH 448/885] fix(TWO-25554): route the billing seed by
 distinctness alone

The billing panel's capture outlived billing being a distinct address, so
every quote billing-address notification routed a returning buyer's saved
company into a panel the resolver does not read. Core's own checkbox is
what retires that capture.

Subject: [PATCH 449/885] fix(TWO-25554): thread the tile's visibility off the
 component's own re-point
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The tile kept a visible, required company field on the one event that moves
the mount, because the renderer's revision counter was bumped only by
callers that remembered to. The harness's Knockout double now tracks
dependencies, so a binding's caching — and a missing notification — is
assertable at all.

Subject: [PATCH 450/885] fix(TWO-25554): keep a per-form record of what the
 autofill wrote

A rebuilt address fieldset takes every autofill marker with it, so a later
country switch retracted nothing and left the previous country's address in
the buyer's form. Keyed on the form element and read only for the form the
calling panel passed in.

Subject: [PATCH 451/885] fix(TWO-25554): give a tile-mounted shipping panel
 the one address form there is
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

A checkout supplying its own address markup left the pick and the sole-trader
write-back with nowhere to land, silently. The destination is that single
form, established before the write and refused — audibly — when it cannot be.

Subject: [PATCH 452/885] fix(TWO-25554): release the field a capture panel has
 lost

A panel whose mount went away kept the field's key handlers, its popover and
its combobox attributes, so the control the buyer left stayed live under the
one they were using.

Subject: [PATCH 453/885] fix(TWO-25554): require a rate-limit scope for a
 company search
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

A scope-less caller was silently given the bind token, which a re-render
replaces — so the 429 backoff it earned expired with it. The panel now names
itself when its host does not, and the model refuses a search with neither.

Subject: [PATCH 454/885] test(TWO-25554): make row descriptions reach the
 failure diff, and tighten two pins

Jest ignores a second argument to `toBe()`, so nine rows carried a
description nothing would ever print. The address step's own pin now checks
an allowlist of the members it may reach for rather than the names of the
writers already gone.

Subject: [PATCH 456/885] fix(TWO-25554): bound each panel's restored-number
 read to its own form
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The ancestor walk had no ceiling, so a panel whose own form carries no
company_id read the other panel's — a cross-panel DOM read the panel split
exists to prevent. The walk now cannot leave the form the field belongs to.

Subject: [PATCH 457/885] fix(TWO-25554): anchor panel chrome beside the
 popover's wrapper

The number label and sole-trader link sat inside `.two-company-field-wrap`,
which the popover is positioned against, so chrome in its flow pushed the
open dropdown off the field. They are siblings after the wrapper, and a test
pins that.

 component renders
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The injection matched only core's own billing-address component, so a
checkout substituting its own — or wrapping core's in a container — got no
company-number field and the feature silently did nothing there. Core's
`billingAddress` scope naming is accepted as well.

Also assert the payment subtree in the neither-container-present row, which
previously asserted nothing about its own subject.

Subject: [PATCH 473/885] fix(TWO-25554): render each panel's address notice at
 its own field

The mirror carries the company fields alone, so no panel's UI state
travels into the identity the tile and order-intent read.

Subject: [PATCH 481/885] refactor(TWO-25554): drop the restored-number
 multi-match check

_ownFormRoot's ceiling is the panel's own address form, and the layout
processor injects exactly one company_id field per form, so no ancestor
inside that ceiling can hold two.

 and headings

Checkout Fields/Order Management/Diagnostics tab headings and every field
under Order Management/Diagnostics missing tax-class defaults, debug/SSL/
admin-controls and health-checklist labels had no CSV row in any locale,
matching the same gap in woocommerce-plugin (TWO-i18n).

Order Management/Diagnostics/Checkout Fields headings are ported from
prestashop-plugin's existing human translations; Enable debug logging and
Disable SSL verification are ported from woocommerce-plugin's. The rest is
machine-translated and unreviewed.

Subject: [PATCH 483/885] fix: sentence-case admin captions and reconnect their
 translations

TWO-25498 re-introduced Title Case on captions that TWO-25326 had
sentence-cased, which also orphaned the sentence-case i18n rows still
carrying their human translations. Renames the catalogue keys with the
captions so those translations follow.

Subject: [PATCH 484/885] fix: translate the untranslated admin surface and
 gate it in CI
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

45 rows per locale, mostly recovered from the sibling plugins' existing
human translations. Also corrects nb/sv "Health", which rendered as
bodily health, and a "brower" typo in the firewall-token help.

The new gate asserts every admin caption has a non-empty row in all
three locales and that no caption is Title Case — this is the second
round of the same defect, so it needs a check rather than another sweep.

Subject: [PATCH 485/885] fix: extend the catalogue gate to admin copy that
 goes through __()

Checklist values, grid headers, dropdown options and validation
refusals reach the screen from PHP rather than a form definition, so
the XML-only gate would not have caught the round this PR fixes.
Concatenated msgids are joined the way Magento looks them up.

Also realigns prose that quotes a live label with that label's casing.

From 26a5acc0cad0f0c6d9ecd1ca18bd3d7b5f5f9761 Mon Sep 17 00:00:00 2001

Subject: [PATCH 489/885] fix: show the surcharge net or gross per the store's
 tax display setting

Every buyer- and merchant-facing surcharge amount was rendered net
regardless of configuration, so a store set to show gross prices showed
a net surcharge beside gross everything else.

Net and tax were already snapshotted at each entity's creation time, so
this is display-only: Service\Order\SurchargeDisplay reads the store's
"Display Prices" switch for the cart and sales tiers and each renderer
picks accordingly. "Both" emits the paired excl/incl rows core uses for
Subtotal and Shipping.

Subject: [PATCH 490/885] refactor: drop the log dependency TermSelection no
 longer uses

Per-term failure logging moved into TermSurchargePreview, and pin the
predicate core's TotalsReader uses to split a multi-row fetch().

Subject: [PATCH 491/885] fix: chip surcharge shows net in Both display mode

displayedTermSurcharges() picked gross whenever mode was not 'excl',
so Both mode (which shows both rows in the order-summary total) fed
gross into the single-value chip too. Only 'incl' should select
gross; 'excl' and 'both' now both resolve to net.

Subject: [PATCH 492/885] feat: replace the firewall token field with a custom
 request header table

ABN-490. The single X-WAF-TOKEN field and its "also send from browser"
toggle become a Diagnostics header table: any number of admin-named
headers, each with its own browser tick. A data patch carries a
configured token onto the new table as one X-WAF-TOKEN row.

Subject: [PATCH 493/885] fix: resolve the migrated browser flag through the
 full scope chain
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Review round 1: a store-scoped firewall token whose browser toggle was
only ticked on its website inherited that tick, but the migration jumped
straight from the token's own scope to default — publishing a header the
merchant never ticked, or dropping one they had.

Subject: [PATCH 494/885] fix: refuse a line break in a header value, and
 tighten the read path
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Review round 1. A value carrying CR/LF closed the header and forged the
next one, reserved names included, since only the name was pattern-gated
— refused at entry and dropped on read. Also: a locked (app:config:dump)
value now still renders its rows, the read path folds header-name case
the way the entry gate does, a failed encode refuses instead of silently
wiping the table, the migration's LIKE pattern escapes its own
underscore, and the "no header name" notice names the row not the value.

From d36661fbf3ee1a71163549593cd07151f08bc671 Mon Sep 17 00:00:00 2001

Subject: [PATCH 495/885] fix: hold the migrated token to the same entry rules
 as a typed one

Review round 2. The migration wrote the old token into the new table
unvalidated: an interior line break stored a row the entry gate refuses,
wedging every later save of the payment section over something the admin
never typed, and a token JSON could not encode stored as nothing at all
while the retired rows were deleted. Both now skip the write and leave
the token behind.

Also: the outbound collision check folds case, so a stored row cannot add
a second conflicting X-API-Key; the browser call sets its delegated-
authority token after the merchant's rows rather than before; and the
admin copy says a ticked header only works if the API already allows that
name on browser calls.

Subject: [PATCH 496/885] fix: keep a browser tick stored at a narrower scope
 than the token
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Review round 3. The two retired fields were independently scopeable, so
a tick could sit at a narrower scope than the token it applied to — a
default-scope token with the tick set on one store migrated to a single
unticked default row, and that store silently stopped sending the header
from the browser. Both fields are now resolved down the same chain at
every scope either of them touched, and a scope resolving to what it
already inherits gets no row of its own.

Subject: [PATCH 497/885] fix: keep a blanked scope from inheriting an
 ancestor's header
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Review round 4. A scope whose token the merchant had cleared was skipped
entirely, so after migration it inherited an ancestor's row and started
sending a header it had been blanked to suppress — published to every
buyer there if the ancestor was ticked. Such a scope now stores an empty
table, which is how "sends nothing" survives as an override.

Subject: [PATCH 498/885] fix: give the migration's false one meaning

Review round 5. encodeFor() returned json_encode's false alongside its
own "nothing to write", so a token PHP could not encode reopened the
previous round's bug by a second route: the scope was skipped and
started inheriting an ancestor's header. The encode now falls through
to the same blank as any other uncarriable token.

Subject: [PATCH 499/885] fix: keep the header help text translatable for
 overlay brands
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Review round 6. The retired field resolved its help text through a
CommentInterface, so one catalogue row with a %1 placeholder covered
every brand; the replacement baked the brand into the msgid, which no
overlay brand's substituted paragraph can match — their admin rendered
in English, and the i18n coverage test cannot see it because it skips
any string containing a template token.

Also documents what the migration cannot carry: a token locked into
app/etc/config.php by app:config:dump, and one holding bytes a header or
the storage format cannot.

+## The custom-header table: what its migration cannot carry
+
+`custom_headers` (Diagnostics → Admin controls) replaced the single
+`firewall_token` field and its browser toggle.
+`Setup\Patch\Data\MigrateFirewallTokenToCustomHeaders` carries a stored
+token over as one `X-WAF-TOKEN` row, resolving both retired fields down
+the scope chain at every scope either of them touched. Three cases it
+deliberately does not carry, all silent:
+
+-   **A token locked into `app/etc/config.php` by `app:config:dump`.**
+    The patch reads `core_config_data`; a dumped value is not there and a
+    data patch must not rewrite the merchant's config file. Those stores
+    stop sending the header at upgrade and every API call is refused.
+    Needs a release note, not a code fix — check for this first if a
+    merchant reports refusals straight after upgrade.
+-   **A token containing CR/LF or NUL.** The retired field had no
+    validation and sent the raw bytes, which was a header-injection sink.
+    The table refuses it at entry and drops it on read, so the migration
+    writes no row for it.
+-   **A token PHP cannot JSON-encode** (invalid UTF-8). The storage format
+    cannot hold it.
+
+In the last two, a scope that would otherwise INHERIT a header instead
+gets an empty table rather than being skipped — an empty table is how
+"this scope sends nothing" survives as an override, and skipping would
+silently start it sending an ancestor's header (published to buyers if
+that ancestor is ticked). That is why `encodeFor()` distinguishes `''`
+from `false`; collapsing the two reintroduces the bug.
+
+**A browser-ticked header must already be allowed by the API on
+browser-originated calls**, or the one direct call the browser makes
+fails CORS preflight and the sole-trader autofill silently finds no
+buyer. The field help says so; nothing enforces it.

Subject: [PATCH 500/885] revert(TWO-25554): restore the restored-number
 multi-match check

Costs nothing and guards against other faults that could cause
inadvertent double rendering, independent of _ownFormRoot's ceiling.

Subject: [PATCH 501/885] fix(TWO-25554): answer "is billing distinct" from the
 checkbox and the quote
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The single authority behind both the resolver and billingRoleIdentity(): the
buyer's own "same as shipping" box on the ACTIVE payment method, and the
quote's cache-key comparison. A third-party re-render detaches the billing
fieldset for an instant, and a visibility read hands the other panel's field
the company the buyer just picked.

The billing panel's MOUNT predicate is unchanged — it is still the visibility
of the billing company field. On a saved-shipping-address, non-virtual,
search-enabled checkout that leaves the billing panel mounted as the only
control on the page while the quote has not yet diverged, so a pick made
there resolves to shipping's empty identity and is discarded. Awaiting a
product ruling; this commit is self-contained so it can be dropped or amended
on its own.

Subject: [PATCH 502/885] feat: restrict header values to printable ASCII and
 reserve four more names

Header values must now match ^[\x20-\x7E]+\z, refused at save with a
message naming the rule rather than stripped: CR/LF was a
response-splitting sink, control characters a log-injection one, and
non-ASCII is ambiguous on the wire. The anchor is \z because $ matches
before a final newline, which is the byte that matters most. A value is
tidied of spaces and tabs only, so a stray control byte survives to be
named instead of silently disappearing.

RESERVED_NAMES gains accept and accept-language, which the browser-side
call sets itself, plus x-forwarded-for and x-real-ip, held back
defensively as proxy-identity headers a merchant should not restate from
this table.

+-   **A token outside printable ASCII** (`^[\x20-\x7E]+\z`). The retired

Subject: [PATCH 503/885] docs: correct the migration note, and pin what it
 tidies rather than drops

Content-Transfer-Encoding: 8bit

Review round 7. The note said "three cases" after two bullets were
merged, and its inheritance paragraph swept in the app:config:dump case
— those scopes are never candidates, so they get no row of any kind, let
alone a blank override. It also claimed no row is written for any value
offending against printable ASCII, which is untrue where the offending
bytes only surround the token: the migration trims them and carries it,
because an unattended patch has no admin to warn and the trimmed value
is the header the store was sending. That is now pinned both ways.

Also: 0x1F, the byte below the low boundary, was the one range widening
the value tests could not catch; and the reserved-name justification for
accept named the wrong call site — the browser sets it as its own
content negotiation, not fetchBuyer().

Subject: [PATCH 504/885] docs: correct two claims about what trim reaches and
 what the guard buys

Review round 8. trim() only reaches its default charlist, so a stray
\x1B, \x1F, \x7F or high byte is dropped wherever it sits rather than
tidied from the edges; and without the encode guard a false return from
a string-typed method raises a TypeError, it does not store a blank.

Subject: [PATCH 505/885] feat: drop the migration and reserve nineteen header
 names
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The firewall_token field the table replaced never reached main on any
platform, only staging, so no merchant ever had one configured in
production and there was nothing to carry over. Removing the data patch
also dissolves the app:config:dump gap it could not cover: a dumped
value was invisible to it, and now there is no migration to be blind.
Not a breaking change despite the deletion — the field it migrated was
never released, so no upgrade path depended on it.

RESERVED_NAMES grows to nineteen. Beyond the names the integration sets
itself and the proxy identity the rate limiter resolves callers through,
it now holds back RFC 7230 hop-by-hop headers — connection, keep-alive,
proxy-authenticate, proxy-authorization, te, trailer,
transfer-encoding, upgrade — which govern connection handling rather
than request content, so a merchant value there malforms the call
instead of merely overriding something; plus authorization and cookie,
which this plugin never sets but which should not be injectable into a
call to the Two API from an admin table. Matching stays exact, so a
name like X-Upgrade-Path is still the merchant's to use.

From 82c5dcb2157e398d54aa88304f6abd0eb4c557be Mon Sep 17 00:00:00 2001

Subject: [PATCH 506/885] fix: give the reserved-name refusal a reason true of
 all nineteen
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Review round 9. The notice said the name "is set by the extension
itself", which is untrue for ten of the nineteen — the plugin never
sends Cookie, Authorization, TE, Trailer, Upgrade or the proxy-auth
pair. An admin blocked on one of those got a wrong reason.

Also corrects two AGENTS.md claims: the entry gate has more rules than
the two spelled out (empty name, empty value, duplicate name, RFC 7230
name charset), and the note narrated the edit history rather than
stating what holds.

Subject: [PATCH 509/885] test: pin custom-header coverage on every outbound
 call to the API

The header table exists to clear a merchant's firewall, so a call site
that skips it is blocked by that same firewall. Pins the pre-auth
API-key verification call, and fails the build if a new call site
builds its own HTTP client instead of going through the adapter.

Subject: [PATCH 510/885] feat(TWO-40): consult autofill before the sole-trader
 signup popup
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The sole-trader chip now reads the buyer's own Two session first and
adopts that identity silently when it carries a usable company name,
so a buyer Two already knows never sees the hosted signup. Everything
less than a usable record — no session, no buyer, a nameless record, a
failed lookup — falls through to the popup unchanged.

"Select a different sole trader", and re-clicking the chip once a sole
trader is adopted, both skip the check and go straight to the popup:
their whole purpose is overriding what is already on screen.

Reverses the no-pre-authentication-probe control added under TWO-25503,
which held the buyer lookup to the ACCEPTED handshake alone and pinned
that in source. The lookup is not a probe worth blocking: the cookie is
first-party to Two rather than something a third party can forge, and
the endpoint only decodes it and answers, persisting nothing. It reports
only what the buyer has already declared to Two.

Token minting already happens on availability rather than on the click,
so the lookup is the only round trip between the click and window.open()
and the popup stays inside the gesture a blocker will allow.

Subject: [PATCH 511/885] fix(TWO-40): guard the autofill lookup against what
 the buyer does next
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Review round 1 findings.

A lookup still in flight no longer adopts: the buyer can leave
sole-trader mode, or settle an identity inside it, before the answer
lands, and adopting on a stale answer overwrote what they chose —
leaving a sole trader's name, number and address under registered or
manual mode, submitted as a vouched registered company. The mode is
re-asserted after the await, and the popup fall-through is held to the
same check.

One launch at a time: the chip stays clickable until a popup exists, so
a second click raced the first, and the second popup closed and
reopened the first. The click path now returns the launch already in
flight.

One lookup per entry into sole-trader mode, so the retry after a
blocked popup goes straight to the popup rather than asking again.
Leaving the mode re-arms it.

An adoption that throws now falls through to the popup instead of
surfacing as an unhandled rejection with no popup and no explanation.

Also retires three docblocks asserting a same-tick launch invariant the
first-click path no longer holds.

Subject: [PATCH 512/885] fix(TWO-40): hold the popup fall-through to the
 adopted check too

Review round 2 findings, both in round 1's own guards.

The fall-through could not tell "nothing usable found" from "an identity
settled while the lookup was out", so an ACCEPTED handshake landing
mid-lookup raised a fresh signup with autoselect on over the identity it
had just adopted, closing the handshake's own popup to do it. It now
checks soleTraderAdopted() alongside the mode.

A country change reverts the address and re-arms the lookup, but left
the in-flight launch cached, so the next click was handed the lookup for
the country the buyer had left and re-adopted what the change reverted.
The cached launch is dropped with the rest of that state.

A throw out of the fall-through itself now surfaces the signup error
rather than an unhandled rejection.

Subject: [PATCH 513/885] test(TWO-40): cover the launch error surface

Pins the outer rejection handler: a throw out of the fall-through
surfaces the signup error and leaves the chip usable, rather than
resolving to nothing.

Subject: [PATCH 514/885] refactor(TWO-40): decide the sole-trader chip on an
 answer already held
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Moves the buyer lookup off the click and onto the eager token mint, so
the chip decides synchronously on an answer it already has: a held
record is adopted directly, and no record means the popup opens inside
the click's own gesture, exactly as it did before this feature.

The click was asynchronous, which put a mid-flight window between the
gesture and the decision that every state reset — mode change, country
change, handshake adoption, availability flip — could land inside. Three
review rounds produced three generations of guards for that window.
Removing the window removes all of them: the once-per-entry flag, the
in-flight launch slot, the post-await mode re-assertion, the
fall-through helper and the rejection plumbing are all gone.

Two writes keep the held answer honest: any adoption drops it, so a
later click cannot re-adopt it over the identity that won, and retiring
the flow drops it along with the country it belonged to.

A click landing before the lookup has returned reads as "nobody" and
opens the popup. That is the intended degradation, and it costs nothing
that the previous shape did not already cost.

Net 93 lines removed.

+ * TWO-40 — the buyer's own Two session is looked up as soon as sole trader is
+ * on offer, and the chip then decides on the answer it already holds: adopt it
+ * silently, or open the hosted signup inside the click itself.
  *
  * Mutation-resistance notes:
  *
  *  - the silent-adoption cases assert the popup count is ZERO, not merely that
- *    a name landed, so falling through to the popup as well as adopting fails;
- *  - every fall-through case asserts the lookup DID go out before the popup
- *    opened, so deleting the autofill call and passing on the popup assertions
- *    alone is not green;
- *  - "select a different sole trader" is pinned on the lookup COUNT, not just
- *    on the popup opening: routing that link through the autofill check would
- *    still open a popup on a 404, and only the count catches it;
+ *    a name landed, so adopting AND falling through to the popup fails;
+ *  - the fall-through popup is asserted in the SAME TICK as the click, with
+ *    nothing awaited between them, so anything reintroduced between the click
+ *    and the open — a mint, a lookup, a promise hop — fails;
+ *  - every case pins the lookup COUNT, so a click that asks again, a gesture
+ *    that stops asking at boot, and a "select a different sole trader" routed
+ *    through the held record are all distinguishable from the popup opening;
  *  - the usable-record rule is driven with a real nameless buyer rather than by
- *    asserting a predicate exists.
+ *    asserting a predicate exists;

From 1a58afb03f80bc1fb7f9c4a65e2711d64593b9a0 Mon Sep 17 00:00:00 2001
From: Douglas Lindsay <dlindsay@two.inc>
Date: Thu, 3 Sep 2026 17:04:47 +0100
Subject: [PATCH 515/885] fix(TWO-40): keep the held answer across leaving
 sole-trader mode
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Review round 4.

Clearing the held answer lived in forgetAdoptions(), which
leaveSoleTraderMode() also calls, and nothing on that route re-runs the
lookup — so a buyer who clicked before the answer landed, took the
popup, then left the mode had the answer discarded and never looked up
again for the life of the page. Leaving the mode says nothing about who
the session identifies, so the clear now belongs only to the country
change, whose registry the record genuinely no longer matches.

Restores the same-tick popup assertion and drops five awaits that had
been added to the launch path, which between them left nothing failing
if a hop were reintroduced between the click and window.open().

The held answer is never revalidated; the docblock now says so and why
that is accepted rather than leaving it to be inferred.

Subject: [PATCH 516/885] fix(TWO-40): re-arm the lookup when the held answer
 has been spent
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Review round 5.

An adoption clears the held answer but left the lookup memoised, and
leaving sole-trader mode is the only point on that route that can arm
another — so a silent adoption followed by Registered company or Manual
entry left the chip falling to the popup with an empty company field,
and the buyer was never looked up again for the life of the page. Round
4 fixed this for an answer still held; this covers the spent one.

An answer still held is deliberately left alone rather than refreshed:
the session stands behind it either way, and re-running only risks the
next click landing ahead of the answer.

Adds the two orderings the previous round's block did not pin — an
answer arriving after the buyer left the mode, and leaving the mode
after an adoption — the second of which is why this shipped green.

Subject: [PATCH 517/885] docs(TWO-40): state forgetAutofilledBuyer's actual
 callers
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Review round 6, which found no behavioural defect.

The docblock forbade the call leaving sole-trader mode now makes, so the
function's stated contract contradicted its own caller and pointed the
next reader at the shape the previous round fixed. It now names both
callers and what survives each.

Drops the availability half of the re-arm gate: leaving the mode is only
reachable with the chip clickable, which needs availability true, and
the one route that turns it false clears the identity first, so the gate
was never evaluated with it false.

Also drops an overclaim in ensureTokens' docblock — it neither runs nor
awaits the lookup — pins the lookup count on the re-entry cases, and
reverts three test signatures left async with nothing to await.

Subject: [PATCH 518/885] fix(TWO-40): retire the held answer on every country
 change
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Review round 7.

Retiring the held answer sat inside onCountryChanged's first-resolution
guard, but the mount observer can resolve availability — and so hold an
answer — while `_lastCountry` is still empty, which is the sidebar boot
that observer exists for. A real country change then took the
first-resolution branch, kept the answer, found the lookup already
memoised, and adopted a record belonging to the registry the buyer had
just left. It is retired on every change now; the identity guard around
it is untouched, since that one is about not discarding a company the
same address already carried.

Restores the availability half of the re-arm gate, removed last round as
unreachable. It is reachable: refreshSoleTraderAvailability sets
availability false and only then retires the mode, so leaving it would
arm a lookup for a country whose registry offers no sole trader and hold
an answer no chip can reach. Both halves now have a test behind them.

Subject: [PATCH 519/885] fix(TWO-40): discard an autofill answer superseded
 while in flight
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Review round 8, and the root cause the previous four rounds were each
treating a symptom of.

Retiring the held answer only ever cleared what had already arrived.
The lookup's own continuation wrote unconditionally, so a request still
out survived every retirement: a boot lookup landing after the buyer had
signed up as a different trader put the replaced identity back, and the
next chip click adopted it silently. The write is now generation-guarded
— retiring the answer or adopting one bumps the generation, and a
continuation whose generation has moved on writes nothing.

That makes the invalidation call sites a safety net rather than the
mechanism, which is why four rounds of adjusting them kept finding
another ordering.

Corrects two tests whose premise this inverts: an answer in flight when
the buyer leaves the mode is now retired rather than adopted on
re-entry, and what they get is the answer armed after they left.

Subject: [PATCH 520/885] test(TWO-40): pin the always-popup link against a
 held answer

Review round 9, which found no behavioural defect.

The DOM-level case for "Select a different sole trader" claimed to prove
the link ignores a held answer, but the adoption that renders the link
spends the answer, so there was none in front of it and routing the link
through one left the test green. It now holds one deliberately, which is
the only way to construct that state, and fails if the link consults it.

Also drops an overstatement about a nameless record leaving no route
forward: the link is offered on adoption alone, so one exists.

Subject: [PATCH 521/885] test(TWO-40): hold the link's answer through the
 public API
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Review round 10.

The previous commit reached into `_autofillBuyer` and claimed it was the
only way to put an answer in front of the link. Retiring the answer and
re-arming the lookup does it through the flow's own API, and keeping the
lookup count alongside the identity assertion means the one test now
fails both if the link adopts the answer and if it goes asking for one —
where each version so far caught only one of the two.

Also restores a fixture's company types to the branch point: it was
widened while the click path was asynchronous and the awaits that needed
it are gone.

Subject: [PATCH 522/885] test(TWO-40): scope the mutation-resistance notes to
 the cases that carry them

Review round 11.

Two header claims were over-broad quantifiers: not every case pins the
lookup count, and the silent-adoption cases after the first read one
written field each rather than re-asserting a zero popup count. Both now
say which cases carry which guard, so the notes can be trusted as a map
of where a mutation would be caught.

Subject: [PATCH 524/885] fix: reconcile an unitemized charge on an invoice or
 credit memo
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

findVerifiedResidualTaxRate() is documented to reconcile an order, an
invoice or a credit memo, but returned early for anything that was not
an order, so no invoice or credit-memo residual could ever reconcile. It
now resolves either to its own order: the residual on both is a share of
the same order-level charge at the same rate.

It reads those rates from the order's applied_taxes extension attribute
or, when that is empty, from the persisted tax rows. The attribute only
exists on an order built by quote conversion or loaded through the
repository; the admin invoice and credit-memo controllers use
OrderFactory, so it is empty exactly where the merchant works and a
TAXED charge could never reconcile there — only a zero-tax one. This is
the same two-source read the shipping rate already does.

Also drops a stale reference to a fee provider that does not exist.

Subject: [PATCH 525/885] feat: let the merchant refund an unitemized charge on
 a credit memo
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Reconciling the refund payload is not enough on its own. A charge that
reaches the grand total through a totals collector rather than a quote
item belongs to no item and no shipping, so core's own collectors never
carry it onto a credit memo: the refund totals omit it and there is
nothing for the merchant to refund.

Model\Total\Creditmemo\OtherCharges puts the order's residual back,
prorated by refunded subtotal share and capped by what earlier memos
took. Block\Sales\Total\OtherCharges and Model\Pdf\Total\OtherCharges
render it as "Other charges" on every credit-memo surface — admin,
buyer account, guest, both print views, the email and the PDF.

Both take the residual from Service\Order\OtherChargesResolver, which
runs the composition path's own getOtherChargesLineItem() over a new
getKnownLineAmountsOrder() plus any registered provider's fee lines.
Nothing here names or detects an extension: the residual is defined by
what the grand total exceeds. It is gated on the order being a Two
order, resolved by payment-method instance so brand overlays count,
since a store-wide fee extension applies to every order.

Every ceiling — the proration share, the tax allowance and the base
grand-total ceiling validateForRefund() enforces — is applied by solving
the NET at the charge's own rate, so the declared rate survives each
clamp. A charge declared at any other rate is refused by ComposeRefund
while the grand total still carries the money.

@@ -272,6 +272,84 @@ order through `OrderFactory`, which never populates the attribute, so without
 the second source a taxed fee stays unrefundable on exactly the screen the
 merchant uses.
 
+Reconciling the refund payload is not enough on its own, because a fee that
+reaches the grand total through a totals collector rather than a quote item
+never reaches the credit memo at all — the refund totals omit it and the
+merchant cannot refund it. `Model\Total\Creditmemo\OtherCharges` prorates the
+order's residual onto the credit memo by refunded subtotal share, and
+`Block\Sales\Total\OtherCharges` renders it as "Other charges".
+
+Both take the residual from `Service\Order\OtherChargesResolver`, which runs
+the composition path's own `getOtherChargesLineItem()` over
+`getKnownLineAmountsOrder()` plus any registered provider's fee lines — the
+same reconciliation `reconcileOtherCharges()` performs. None of it names an
+extension: the residual is defined by what the grand total exceeds, never by
+whose fee it is. The collector is gated on the order being a
+Two order — by payment-method INSTANCE, since a brand overlay's
+`GenericPaymentMethod` extends `Two` under its own per-brand code — because a
+store-wide fee extension applies to every order and this module has no
+business moving anyone else's refund total.
+
+`getKnownLineAmountsOrder()` counts what composition *should* itemize, which
+is deliberately not identical to what it actually emits. Two known
+divergences: it counts an item whose product no longer loads, where
+`getLineItemsOrder()` drops it and the dropped item's own value would read as
+an unitemized fee and be refunded as one; and it reads the surcharge only
+from the order columns, where `ComposeOrder::execute()` still falls back to
+the checkout session. It also loads no products, which a totals collector
+re-run on every credit-memo render cannot afford, and it avoids
+`getShippingLineOrder()`, because resolving the shipping tax rate queries the
+tax engine and throws when none is declared.
+
+**The fee's VAT is not already on the credit memo.** Core's
+`Creditmemo\Total\Tax` builds the tax up from item `tax_invoiced` plus
+shipping tax, then treats the order's allowance two different ways: a `min()`
+ceiling on a partial memo, but a straight assignment on the last one (and only
+when shipping is not partially refunded). So a fee belonging to no item and no
+shipping is in `tax_amount` already on that last memo and absent on every
+other. This is the one place it diverges from the sibling
+`Creditmemo\Surcharge` collector, which *assumes* core's native proration
+already granted its own VAT — an assumption that holds on the last memo and
+fails on a partial one.
+
+How much core granted THIS fee is read the way `ComposeRefund` reads it — the
+memo's tax less the tax of every line composition itemizes (items, shipping,
+surcharge), in ORDER currency, where the payload evaluates its residual —
+never from the tax headroom, which can be zero for reasons unrelated to the
+fee, and never in base currency, which desyncs the two on a converted order.
+
+**Every ceiling is applied by solving the NET, at the fee's own rate.** There
+are three: the proration share (less what earlier memos took), the tax
+allowance, and `validateForRefund()`'s base grand-total ceiling. Clamping a
+net and a VAT that were chosen separately cannot preserve a rate — scaling
+two legs while the already-granted VAT stays fixed changes the quotient — and
+a fee declared at any other rate is refused by `ComposeRefund` while the
+grand total still carries the money. So the net is solved as the minimum
+those ceilings allow and the VAT follows from it: `taxDelta = rate × net −
+granted`. A smaller share refunded at the exact rate beats the whole share at
+a wrong one. Entitlement is cumulative — `feeNet × (refunded subtotal share
+including this memo) − already refunded` — so a share an earlier memo could
+not take is recovered by a later one rather than stranded, and the last memo
+lands on the whole charge exactly with no rounding residue. The one exception
+is the stranding case below.
+
+Three cases defer rather than pay out, all logging `OtherChargesDeferred`. A
+NEGATIVE granted amount means some other total's tax is missing from the
+memo — on a partial memo of a surcharged order core omits the surcharge VAT
+that `ComposeRefund` declares in its surcharge line — and adding it here
+would refund another total's VAT under this fee's name and at a rate that is
+not this fee's. A granted amount larger than `rate × net` cannot be reduced,
+since the collector only ever adds tax. And no ceiling leaving any room at
+all resolves the net to zero.
+
+**Known gap: a surcharged order refunded across two or more partial memos
+strands the fee permanently**, rather than deferring it to a memo that can
+state it. Memo 1 defers on the negative granted amount; the last memo's
+granted then contains the surcharge VAT memo 1 never booked, so it defers
+again. No money is misstated — this is the pre-existing behaviour for that
+configuration — and the root cause is `Creditmemo\Surcharge`'s tax-delta
+assumption above, not this collector.

From 5a73c1dba65ff1792124eb80fc2aa6291adebee6 Mon Sep 17 00:00:00 2001

Subject: [PATCH 526/885] fix: add missing translations for sole-trader and
 search-error strings

Three company-capture-component strings had no i18n row in nb_NO/nl_NL/sv_SE:
"Select a different sole trader", "Company search is unavailable right now.
Please try again shortly.", and "Could not complete sole trader signup.
Please try again." Machine-translated pending a human pass.

Subject: [PATCH 527/885] fix(TWO-40): stop retiring the held buyer answer on
 country change
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The buyer identity comes from the session cookie, not the registry the
checkout form currently targets, so it has nothing to do with which
country is selected. Round 7 of PR #425 (18582f7e) retired the held
answer on every country change to close a real bug — a stale answer
from a country the buyer had left getting adopted — but that fix
assumed the answer was country-scoped, which it never was. Once the
answer is held regardless of country, that scenario is no longer a bug:
whichever answer is held is still a correct answer for the buyer's own
session.

leaveSoleTraderMode's own re-arm gate (round 7's other hunk, the
`_identity.soleTraderAvailable()` check) is untouched — it decides
whether to bother arming a fresh lookup at all when the current
country's registry offers no sole trader, which is orthogonal to
whether an already-held answer survives a country change.

Subject: [PATCH 528/885] ABN-492: read order-level tax rows when resolving a
 residual's rate

A fee applied at address/total level records its rate only in the
order-level tax rows, which nothing in the plugin read, so a taxed
residual it produced could not be itemized and the fee could not be
refunded. All three of Magento's applied-tax sources are now merged
rather than taken first-non-empty, so an order-level rate is still
found when the item-level rows are populated but do not reconcile.

Subject: [PATCH 529/885] ABN-492: drop a duplicated assignment, tighten the
 source docblock

The constructor assigned the new factory twice. The docblock enumerated the three sources the code already shows; it now carries only the non-obvious parts: where a total-collector fee.s rate lands, and why the sources are merged rather than first-non-empty.

Subject: [PATCH 530/885] ABN-492: refresh the AGENTS.md tax-source paragraph

The doc still described a two-source, first-non-empty read. It now describes the three sources and why all are read. The code docblock keeps the OrderFactory reason the admin screens need a persisted source, and the test asserts the item-level read is keyed by order id.

Subject: [PATCH 532/885] TWO-25547/fix: mint sole-trader tokens off the
 merchant's own country gate
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Delegated-authority mint and buyer autofill were re-derived from
countryCode()'s per-country registry answer, so a change to the
currently-selected billing/shipping country could suppress or re-arm the
mint mid-checkout. Gate is now the merchant's own supported_buyer_countries
restriction intersected with the registry's sole-trader-supported
countries, resolved once at start() and never re-run on a country change.
soleTraderAvailable() (the sole-trader CHIP's visibility) stays
country-dependent — only the mint/autofill trigger moves.

From c9c9a2432e47d3272cb1fc6ee42062e19228237a Mon Sep 17 00:00:00 2001
From: Douglas Lindsay <dlindsay@two.inc>
Date: Fri, 4 Sep 2026 13:57:14 +0100
Subject: [PATCH 533/885] TWO-25547/fix: drop the merchant-country gate, mint
 unconditionally
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Bifrost's sole-trader registry coverage is global, not merchant-specific,
so gating the mint on a merchant buyer-country field added no value.
Reverts the RecordProvider/soleTraderCountryRestriction plumbing and
replaces the three-state gate with an unconditional prefetchBuyer() call
from start() — mint and buyer autofill fire as soon as checkout is
reached, full stop. The country-decoupling fix (never re-derived from
countryCode()) stays.

Subject: [PATCH 534/885] Grey out company search on a country the registry
 does not cover

Bifrost's new /companies/v2/supported-countries route lets the merchant
plugin disable (not hide) the search field on a country it cannot serve,
instead of letting the buyer search and fail. Fails open on any error or
on a host that has not wired the new option up.

Subject: [PATCH 536/885] Never disable manual entry through the country-search
 gate

Manual entry hands the field over as a plain typeable input that never
reaches the registry search; setDisabled() was writing the native
disabled flag onto it too on an unsupported country, silently blocking
a mode that was never going to search in the first place.

Subject: [PATCH 538/885] fix(TWO-25668): unwrap the JSON-encoded string
 envelope before reading it
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

`CompanyLookupInterface::supportedCountries()` returns a JSON-encoded
string, like `search()`/`get()` already do — company-search.js's working
code already knows to JSON.parse it a second time
(`unwrapProxyResponse()`). The new company-search country-gate code read
`response.json()` as the envelope object directly, so `envelope.ok` was
always undefined, the gate silently failed open on every request, and
the mismatch was masked by a test fixture that mocked the wrong (already
decoded) response shape.

Subject: [PATCH 539/885] fix(TWO-25547): don't memoise a failed sole-trader
 mint forever
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

prefetchBuyer() cached its resolved-null answer permanently, even when
the reason was a transient mint failure (network error, non-ok
response) rather than a genuine "no sole trader" lookup — one bad load
cost the whole page its mint for good, with no way to retry short of a
full reload. A failed mint now clears the memoised attempt, so the next
call (e.g. the re-arm on leaving sole-trader mode) gets a fresh try. A
successful mint still stays memoised, as designed.

Split out of #432, which bundled this real fix into a wider structural
rewrite that breaks Hyva (see F003) — this is the safe subset.

Subject: [PATCH 540/885] fix(TWO-25668): unwrap a one-element array envelope
 in the capture component

Magento's REST layer sometimes returns the single envelope inside a
one-element array, which the inline copy of unwrapProxyResponse() in
the capture component did not handle, so the supported-countries gate
fell through to fail-open on those responses.

Subject: [PATCH 541/885] fix(TWO-25547): a failed sole-trader mint must answer
 nothing

A failed mint attempt still ran the lookup's write step and set the held
autofill buyer to null at the same generation, so two overlapping
prefetches let a stale failure clobber a good buyer. It also cleared the
memoised attempt unconditionally, discarding a newer attempt's.

Subject: [PATCH 544/885] test: trim the mint-retry suite header to the ticket
 and what it pins

Move the mutation-resistance reasoning to the PR body and drop the helper
docblocks that only restated what the helpers do.

Subject: [PATCH 545/885] TWO-25641: log when the method is hidden for a
 below-minimum basket

The below-minimum withholding branch was the only gate in isAvailable()
leaving no diagnostic trace. Adds a debug log carrying the binding floor,
the evaluated basket value and currency, and the threshold.

Log-only; no change to which quotes pass or fail.

Subject: [PATCH 546/885] fix(TWO-25641): neutral wording, drop the
 now-redundant collector line

The gate is also called by the surcharge total collector, where nothing is
hidden from checkout - a fee was skipped. Wording now states only what the
gate decided, and the collector's own line goes since the gate's carries the
numbers.

isAvailable() now says the method was hidden, greppable with the sibling
withholding lines, while the gate's own line carries the numbers. The
surcharge collector keeps one correctly-worded line.

Subject: [PATCH 548/885] fix(TWO-25641): say the gate withheld, not why, and
 keep the collector's marker

The gate also fails closed on unconvertible FX, so naming below-minimum at the
caller was a wrong diagnosis on the one surface this exists to diagnose. The
collector's own marked line comes back so the two callers stay distinguishable.

Subject: [PATCH 550/885] feat(TWO-25641): name the reason in every branch that
 hides the method

Q12(c): each withholding branch in isAvailable() logs its own reason.
The two silent branches (core's verdict, absent API key) now log; the
shared exit line is gone, since one message for several causes diagnoses
none of them. The minimum-order reason stays inside the gate, where the
floor and the basket value are in scope.

Subject: [PATCH 551/885] fix(TWO-25641): read the method's config at the
 quote's store scope

Review nit: parent::isAvailable() judges the quote's scope, so the
unscoped active and api_key reads could report a store-level setting as
its global value. Both now go through one scoped helper; the store-id
derivation moves above the first read that needs it.

Subject: [PATCH 552/885] fix(TWO-25641): keep the custom-days field visible
 when its value is invalid

The field is hidden unless already configured, and hidden when its value
folds into an offered term's checkbox on save. Both are deliberate. But
the single reveal test also hid an unparseable entry, and Magento skips
hidden fields when validating - so a merchant's typo vanished with the
field and validate-digits never fired.

The decision moves to a pure predicate so the three states are testable
without a DOM harness.

Subject: [PATCH 562/885] TWO-25654: close the signup popup on any return to
 checkout but the chip

The exemption keyed on the whole capture popover, so a click on any other
control in it kept the popup up. Worse, since the window focus event fires
only on a focus transition and such a click never takes focus off the page,
nothing afterwards could close the popup at all.

The Sole trader chip's own click already cancels the pending close through
focusSignupPopup(), which leaves the popover check as the only stateful part
of the rule. Removed, along with the coupling to the panel it needed.

Subject: [PATCH 563/885] fix(checkout): refuse order placement after a
 declined order intent (TWO-25657)

The renderer showed the "not available" notice but left Place Order live, so
a buyer could submit an order the pre-check had already declined.

Subject: [PATCH 570/885] TWO-25657: disable Place Order on Luma while intent
 is declined
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The button's enable binding read only whether the method was selected, so
the declined-intent latch never reached the disabled attribute — it added a
CSS class that core's billing-address subscription then cleared. The button
now binds to isPlaceOrderEnabled(), which reads the verdict directly, and
the verdict is an observable so the binding re-evaluates when it lands.

Subject: [PATCH 571/885] fix(TWO-25656): hide the payment terms type selector
 unless already set to end of month

Same hidden-unless-configured gate as default_shipping_tax_rate, now one
Field::isVisible() plugin keyed section_suffix/group/field with a value
predicate per field. Sections match `two_` and each installed brand's
section prefix exactly; the field's own config path is read at the
edited scope (effective value, so website scope reads the website row
and a brand form reads its brand row).

Subject: [PATCH 572/885] TWO-25653: re-run the buyer prefetch after a
 successful mint that follows a failed boot mint

A failed boot mint released the lookup's memo with nothing left to
re-invoke it, so an enrolled sole trader met the signup popup for the
rest of the page. A mint that succeeds afterwards now re-runs the
lookup, and a failed mint schedules one jittered retry (never for a
4xx that settles the request). The lookup is gated on the autofill
token alone, so a 200 carrying an empty delegation token still finds
the buyer while the retry recovers the popup's token.

Subject: [PATCH 573/885] ABN-493, ABN-495: validate custom and default payment
 terms against the offered set

Renders the custom-days help text from the stored payment terms type so
End-of-Month wording only appears under End of Month.

Subject: [PATCH 575/885] Fail loud on an unrecognised stored surcharge method

An unrecognised surcharge_type passed the `!== none` gates and priced the
order at 0% under a method nothing understood; the save path accepted any
string. Loud at save and where the fee is priced or the order created; the
availability gate and the totals collector withdraw/zero Two only (Q54).
The buyer sees the same generic wording placement already uses; the value
reaches the log and the admin message, which core escapes on render.

Subject: [PATCH 576/885] feat: refresh the merchant record on startup, nightly
 and on demand
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The merchant record was a pure TTL cache. It is now refreshed by event —
cache miss, a General section save that changes the API key or the
environment, nightly cron, Diagnostics button. Prompt refresh needs a
running cron; the 1h lifetime is the staleness ceiling on an install
without one. The cached record is replaced on a successful fetch and
left in place on failure; a failure is never cached as the record, only
a 60s read-path cooldown, armed before the fetch so concurrent renders
during an outage share one attempt and cleared when the fetch succeeds.
Record and cooldown live under a dedicated two_gateway cache type, so
cache:clean two_gateway drops them and a config clean does not.

The record is cached per (environment, API key) while the admin saves at
a default / website / store scope. RecordRefresher::governedIdentities()
is the one place that translation happens: the identities a scope governs
are those read by store views under it through the API key set at that
scope, read explicitly at that scope — the default scope is read as
such, never through the area-dependent current store. The scope walk
hands the key it read to every caller, including the FX rate cron, so
no caller resolves it a second time. RecordRefresher::refreshWithin()
is the one refresh loop — observer (15s budget), button (20s budget,
unreached identities reported) and cron — and contains a throwing
identity, logging it at error level.

- * verify_api_key resolves the id the merchant endpoint needs. The

Subject: [PATCH 577/885] feat: allow a brand overlay to reword or suppress the
 declined notice

Ruling 19.5: the "order intent NOT approved" tile notice gets its own
brand.xml switch and copy override, mirroring the approved notice.

A declared declined switch decides whether it renders; absent one, it
renders when non-empty declined copy or the approved switch says so, so
an overlay declaring only the approved switch is unchanged. Visually
blank copy stays inert, non-breaking and zero-width spaces included.

Substituting the company tokens now replaces every occurrence, so an
override template naming the buyer twice no longer leaks a raw token
into the payment tile.

Deletes the unreferenced Model/Brand value object, whose docblock told
overlays to wire it via a virtualType that would fatal on first render.

Subject: [PATCH 578/885] ABN-493, ABN-495: withhold the method while the
 merchant record is unresolvable

Fail closed on an unreachable merchant configuration: the payment method is
not offered, and no stored term reaches the buyer unvalidated. Reworded the
End-of-Month custom-days help text and retranslated it.

+## Admin settings fail loud: an unrecognised stored value is never priced

+The standard for EVERY admin setting, not only the surcharge method.
+
+**Save refuses it.** A value outside the field's known set is rejected by the
+field's backend model. A crafted POST, a hand-edited row, `config:set` or an
+import therefore cannot leave behind a value nothing understands.
+
+**Read paths raise.** The config repository is the single choke point for the
+runtime read: it maps only the explicit unset key to the field's default and
+raises a `LocalizedException` for anything else. Callers that price a fee or
+build an order let that raise.
+
+**Gates and totals collectors catch it.** The availability gate withdraws the
+Two payment method and nothing else; the totals collector clears its own
+segment and returns. Every other payment method, and the rest of checkout, is
+untouched. The repository reports the offending value once per request, so the
+catchers stay quiet.
+
+**Buyer copy stays generic.** The buyer sees the existing "not available for
+this order" wording. A setting name, a stored value or an enum key never
+reaches the storefront — those belong in the log and in the admin field's own
+validation message.
+
+Degrading a junk value to a working default is the failure this replaces: it
+prices an order under a configuration nobody chose, and nobody is told.

Subject: [PATCH 581/885] fix(TWO-25658): focus arriving on the Sole trader
 chip leaves the popup alone

Only an activation of that chip moves the popup: a click, or the Enter or
Space the browser delivers as one. Focus merely arriving on it is inert and
leaves the popup exactly as the buyer left it, open or closed.

The company field joins the popover for the close-the-popover rule. It is the
popover's own trigger and sits outside the panel node, so arriving on it used
to close the search results the buyer was typing against. The popup still
closes, as it does for every control that is not that chip.

Subject: [PATCH 583/885] fix: refresh the merchant record ahead of eviction
 and bound every fetch

The cached record now lives 26h and an hourly cron refreshes it once it
is 24h old, so the record is replaced before it can be evicted and a
failed fetch keeps serving the last good values. The success stamp is
stored with it; a read that finds no record logs a stopped-cron signal
and Diagnostics reports the last successful refresh.

Each of the two GETs is capped at 10s, so the config-save observer's and
the admin button's wall-clock budgets bound what they claim to.

Subject: [PATCH 584/885] TWO-25503/fix: drop the company field's tab stop
 while the popover is open
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The field's focus opener moves the caret into the popover's query input, so a
tab stop on the field catches shift+Tab coming back out of the query and pushes
it forward again — the buyer cannot reach any control above the company field
(WCAG 2.1.2). The field carries no tab stop while the popover is open, and gets
back exactly the tabindex it had when it closes.

jsdom implements no sequential focus navigation, so the tests assert the
tab-stop state rather than the key sequence; the reverse-Tab route out is
verified in a real browser.

+## The company-search panel is ONE module, vendored twice
+
+`view/frontend/web/js/model/company-search-panel.js` is the implementation and
+the WooCommerce plugin carries a copy of the same file, so **a change to shared
+panel behaviour is TWO edits**. Nothing links the two copies; whoever changes
+one and stops has fixed one platform, and the divergence is invisible to both
+reviewers. The `_bindFieldOpeners` block is identical in both.
+
+It is framework-free with a UMD tail — no RequireJS, no jQuery, no Knockout —
+which is what lets the Hyvä checkout load this repo's own copy by
+`Two_Gateway::` reference instead of reimplementing the panel. Anything that
+makes it depend on this checkout's framework breaks that arrangement.
+
+**The unsupported-country gate greys out SEARCH, never manual entry.** Manual
+entry hands the field over as a plain typeable input that never reaches the
+registry, so the native `disabled` flag there blocks a mode that was never going
+to search — and leaves a buyer in an uncovered country with no way to name their
+company at all.
+
+**The company field opens the panel on FOCUS**, through the same `open()` a
+mousedown runs, which puts the caret in the panel's query field. The
+PrestaShop module deliberately does the opposite — there only a click or a
+keypress opens it and focus alone is inert, stated in that module's own code.
+Those two behaviours are the current state of the two platforms; do not assume
+parity, and do not harmonise one to the other without a product ruling.
+
+## What focus landing on the checkout does to an open signup popup
+
+Every `focusin` while the hosted sole-trader signup window is up is classified
+once, and these are the three rules (TWO-25658):
+
+-   **The role's own Sole trader chip is inert.** Arrival moves the popup
+    neither way — only an activation raises it, and the browser delivers Enter
+    and Space on a focused chip as a click.
+-   **Any other target closes an open popup.**
+-   **A target outside that role's popover closes the popover too**, with the
+    company field counted as INSIDE it: the field is the popover's own trigger
+    and sits outside the panel node, so treating it as outside tore down the
+    results the buyer was still typing against.
+
+A window or application switch lands on no control at all and settles nothing.
+
+**A declined order intent refuses order placement, and it does so through the
+Place Order button's own BINDING** — `isPlaceOrderEnabled()` over an observable
+verdict, never an imperative class or attribute write (TWO-25657). Core's
+billing-address subscription re-evaluates that button and clears anything
+written onto it from outside the binding, silently, so an imperative disable
+lasts until the buyer touches an address field.
+
+## A popup window is in no tab listing
+
+`window.open` returns a window outside the browser extension's tab group, so a
+tab list can never answer "did the popup open" — nor can a hang. The
+authoritative check is the page's own retained handle and its `.closed`, which
+means wrapping `window.open` before the action that should raise one. Judging
+from a tab list yields a confident false "no window opened".
+
+## jsdom cannot verify keyboard navigation
+
+jsdom implements no sequential focus navigation: a dispatched `Tab` keydown
+moves focus nowhere, so no jsdom suite can observe a focus trap, a wrong tab
+order or a reverse-Tab dead end, however many cases it carries and however
+green it is. Assert the observable proxy instead — that the handler leaves the
+event undefaulted, that the control's parts are one contiguous run in document
+order, that a closed panel carries `hidden` — and say in the suite that the
+keyboard behaviour itself is verified in a real browser. A passing jsdom Tab
+test is never evidence that a trap is absent.
+
+## A guard is invoked through `bash`
+
+A script committed mode `100644` and run as `./script.sh` exits 126. On a CI
+dashboard that is indistinguishable from a check that ran and failed, so the
+guard's own absence reads as its verdict. Invoke anything whose failure mode is
+"did not execute" as `bash script.sh`, and have it print what it checked.

Subject: [PATCH 588/885] TWO-25503/fix: a rebuilt popover leaves the field
 closed
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

`_buildPanel` builds its panel hidden, so the panel state it establishes is
closed: it now says so and hands the field's tab stop back. A host that
re-renders its own container while the popover is open no longer strands the
field out of the tab order with `aria-expanded="true"` and nothing on screen.
`_holdFieldTabStop()` is left with one call site, `open()`.

`unmount()` releases the tab stop too — it was the one closed-state exit that
left the field it gave back out of the tab order.

Subject: [PATCH 597/885] TWO/chore: compress the merchant-record refresh
 timings for a live dev-shop pass

Temporary, reverted before release: 5 min cache lifetime, 2 min max age,
a per-minute cron and a LIVEVERIFY debug line per fetch, scheduled run and
credential-changing save, so a full refresh cycle is observable inside one
session on a dev shop.

Subject: [PATCH 598/885] TWO/chore: keep the temporary timings to the ones the
 unit suite tolerates

The per-save debug line and the shortened fetch timeout both contradicted
assertions that pin the observer's one log call and the per-call timeout; a
credential save is already visible through the per-fetch line.

Subject: [PATCH 599/885] TWO-25103/fix: key the FX rate table cache on the
 mode as well as the key

One API key can be configured against sandbox on one store view and
production on another, and the rate-table cache slot was the key hash
alone, so the two store views shared a slot and one was served the other
environment's table until the entry was flushed.

The slot is now (mode, key), the shape ApiKeyStatus and RecordProvider
already use. Both caches the scope walk serves are keyed the same way, so
the walk no longer takes a per-caller identity callable.

Subject: [PATCH 600/885] TWO-25103/fix: fetch the rates from the environment
 the slot names
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The slot carried the mode but the fetch did not, so the cron could hit the
store scope's environment and persist that table under the caller's slot —
the same collision, moved to the write side. The scope walk also dedups on
the (mode, key) tuple rather than a copy of a provider's hash.

Subject: [PATCH 601/885] TWO-25103/fix: refuse a slot whose environment is
 unset

A blank mode is one Adapter resolves for itself, so the fetch would hit an
environment the slot does not name. No slot, no fetch. The failed-refresh
log now says which environment failed, since one key holds two slots.

Subject: [PATCH 602/885] TWO-25103/fix: report a scope with no environment
 configured

A blank mode withheld the rate table silently; the repo's standard is that
an unrecognised stored setting is reported once and never priced.

Subject: [PATCH 603/885] TWO/fix: render the merchant-profile refresh button
 in the Diagnostics pane

The pane is built from the fields synthesised out of brand_form_template.xml,
and the deep merge against system.xml only overrides attributes on fields the
template already declares, so the button existed in system.xml and rendered
nowhere. Verified missing on a dev shop before the fix.

Subject: [PATCH 604/885] ABN-495/fix: a rejected API key blocks only the key
 field

An exception in a config backend model rolls back the whole section, so a
mistyped key discarded every other field submitted with it. The key field
turns off its own save instead and reports the rejection to the admin.

Subject: [PATCH 605/885] ABN-495/test: name the real sibling field, drop a
 duplicate verdict row
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The sibling text field posted beside the key is `vendor_site_name`, not
`vendor_name`, and the added `timeout` provider row carried inputs
identical to the existing `unreachable` row — ApiKeyStatus has no
separate timeout verdict. Rationale comments cut to the non-obvious line.

Subject: [PATCH 611/885] TWO/fix: enable the two_gateway cache type on install
 and upgrade

A cache type absent from env.php resolves as disabled and cache.xml has no
default-state attribute, so the module's own type shipped off. While off,
cleaning it is accepted and drops nothing.

A data patch enables it once, via the cache manager, on both a fresh install
and an upgrade. CI asserts cache:status on both paths.

Subject: [PATCH 613/885] ABN-509/fix: hold the ref check to the same deadline
 as reachability
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The first 200 from a store mid-redeploy is served off the old static version,
so checking the digest once behind a single-200 wait turns a not-settled-yet
store into a wrong-store verdict — the false red this guard exists to stop.
Both legs now share one five-minute deadline and the message names whichever
leg was still failing when it expired.

Subject: [PATCH 615/885] TWO-25658/feat: another capture's Sole trader chip
 gets a popup of its own

This checkout mounts two captures, shipping and billing, each with its own
panel, chips and sole-trader flow. Focus arriving on the other capture's Sole
trader chip took this capture's signup popup down and launched nothing, so a
keyboard buyer moving between the two was left with no popup at all. The chip
focus landed on is now activated after the close, its own click handler being
the one place a launch is spelled out.

The return-to-checkout suite left every flow it loaded armed on `document`, so
each earlier test's flow judged the next test's focus against its own open
popup. Released between tests.

Review findings on this PR:

- the two new cases were near-identical discrete tests; they are now one
  `test.each` table in the file's established shape, description last and
  carried into the assertion message by `tagged()`
- `loadedFlows` was declared between `load()`'s JSDoc and `load()` itself,
  so that `@returns` documented the const
- three comments over the one-line bar

Subject: [PATCH 617/885] TWO-25658/fix: the launching chip stays exempt across
 a re-render
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

`getPanelElement()` hands back the node the panel built, and a host that morphs
its server markup over the live DOM deletes the wrap and the popover with it
while keeping the field. Until the panel's observer rebuilds, the stored node is
detached, so this capture's own re-rendered Sole trader chip was contained by
nothing and read as another capture's: focus returning to the very chip that
launched the popup closed it, closed the capture popover, and activated the chip
for a fresh popup in place of the resumable one.

This capture's controls are now resolved off the field on every event — the wrap
when it is there, the field's own parent when the re-render took it — which is
what the WooCommerce copy does.

Subject: [PATCH 618/885] TWO-25658/fix: the popover is the field's sibling,
 not any descendant
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Resolving it under the wrap-or-parent meant that when a re-render had taken the
wrap, the ceiling widened to whatever container the field sits in — and a
container holding two captures answers a descendant search with whichever
popover comes first in the document, which is not necessarily this capture's.
`isBound()` already holds the field and the popover to one parent, so a scan of
the field's own siblings is both tighter and the invariant the panel asserts.

 about the emitted basket

The payment-information endpoint re-runs isAvailable against the PERSISTED
quote. A client-estimated shipping choice is not saved until the shipping step
is submitted, so the verdict can be about a different order value than the one
that triggered the refresh - measured on the dev shop as 50.99 server-side
against 61.188/66.188 live. Publishing it withheld the method on a stale
below-minimum total that then never moved, so nothing restored it.

Subject: [PATCH 627/885] ABN-509/test: submit each minimum crossing so the
 gate judges it

A shipping choice is estimated client-side; the quote the gate reads only
learns about it when the shipping step is submitted. Crossing the minimum
without submitting left the server judging the same unchanged order value
every time, so the closed assertion passed on a value the buyer never had and
the re-open assertion could not pass at all.

- the key is compared against the server's own totals, so raw float text could
  make one basket read as two and reject every response; fixed precision.
- the return to the shipping step did not wait for it, so the submit that
  follows could early-return and never persist the new choice.
- the absence assertion also passed on the empty list the payment service shows
  mid-repopulation; it now requires a control method to be present.
- the restore hook inherited the config timeout, not the test's, on the one run
  it exists for.

Subject: [PATCH 632/885] ABN-509/test: pin the control method and make the
 retry assertion real

- the closed assertion depended on Check/Money Order being enabled on the
  store; it now uses whatever second method the store offered at baseline.
- the rollback-retry assertion re-emitted a different total, so it passed
  whether or not the key rolled back; it re-emits the same one.
- the storage stub returned no totals segment, which the real endpoint always
  sends, so most cases only ever exercised the reject branch.
- the class doc claimed a benefit for a checkout that never persists the
  shipping choice mid-flow, where this component is now a no-op.

Subject: [PATCH 633/885] fix: never expire the cached merchant record
 (ABN-519)

The record entry and its success stamp are written with no lifetime, so
only the scheduled refresh replaces them. A key that stops verifying now
costs the merchant the buyer-facing payment method and nothing else.

A record older than 26 hours means the scheduled refresh is not running,
so a read stands in for it once an hour and returns the held record
either way. Staleness withholds nothing and is reported on the admin
health checklist.

Subject: [PATCH 634/885] ABN-510: enforce one open company-search popover at
 open time

A pointer press on a second capture need not deliver a focus event to the
control it hits, so the focus-driven close never fired and two popovers
could coexist. Opening one now closes any other, and the popover that
closes gives its own field's tab stop back first.

Subject: [PATCH 636/885] fix: only the api-key check may withhold the payment
 method (ABN-519)

An unresolvable merchant record no longer takes the method off the
storefront. A record fetch that 5xxes, times out or cannot reach the host
says nothing about whether the key works, and the key verdict is what
must propagate a revoked key promptly.

Two.php no longer reads SettingsProvider; the constructor argument stays
for the brand overlay that mirrors this constructor positionally.

Subject: [PATCH 637/885] fix: keep the admin fee figures and say when they are
 not current (ABN-512)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The fee beside each payment term was fetched live with no cached copy, so
any upstream failure left every fee blank — indistinguishable from a term
that carries no fee.

The fee set is now cached per merchant, buyer country and term list with
no expiry, and served when a live fetch fails. The screen says the
figures could not be refreshed and when they were retrieved, or that the
pricing service could not be reached when nothing is held.

Subject: [PATCH 640/885] TWO-25669/chore: drop internal-review citations from
 code comments

Public-repo hygiene: comments and test docblocks cited an internal review
document's numbered iterations and a reviewer alias. They now state the
current fact and cite the Linear ticket only. No behaviour change.

Subject: [PATCH 645/885] fix: bound the stand-in refresh and stop the absent
 mark freezing (ABN-519)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Review round findings.

A read standing in for a dead cron now gets a two-second budget rather
than the cron's ten, so a page render never waits on it, and a record
with no success stamp is left to the cron, which already counts it due.

The absent-on-read mark no longer expires, so a successful fetch clears
it — otherwise the health row reported a miss that had been answered.

AGENTS.md corrected: the surcharge FX gate and the minimum-order gate
resolve their rate table from Two, not from store configuration. Both
survive an outage because that table is cached with no expiry and keeps
its last-known-good, which is why they are left as they are.

Subject: [PATCH 646/885] fix: harden the fee fallback and clear the notice on
 recovery (ABN-512)

Review round findings.

A 200 pricing nothing, and an adapter that raises rather than answering,
are both failed fetches now: neither overwrites the last retrieved set,
and both reach the notice. A failed fetch is not retried for a minute
and is bounded at ten seconds, so an outage is not a blocking call per
render.

The notice is cleared whenever a fetch answers with a renderable set, so
a stale note never outlives the figures it described. The retrieval time
is formatted server-side in the admin's own locale and timezone.

The three new admin strings are translated in all three locales.

Subject: [PATCH 647/885] TWO-25669/chore: cite the ticket instead of the
 internal document

Comments, docblocks, docs prose and Jest titles now carry the Linear
ticket where they previously carried section and item numbers of a
private working document (TWO-25669).

Subject: [PATCH 649/885] fix: report a dead schedule from the stand-in mark,
 not the record stamp (ABN-519)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Review round findings.

A read's stand-in refresh moves the success stamp, so the stamp cannot
say whether the scheduled refresh is running — on a trafficked install
with no cron it would have read as healthy forever. The stand-in now
leaves its own mark, cleared by a scheduled run, and the health row
reads that.

The absent-on-read mark is written only when the read could not resolve
a record either, so it no longer erases itself in the same call, and the
admin refresh button can no longer clear it.

Subject: [PATCH 651/885] fix: ask again after an answer that was not current
 (ABN-512)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Review round findings.

The dedup key blocked any further ask for the same term set once a
response was not a fresh renderable one, so a notice and its figures
outlived the outage for the page's life. The key is released on any such
response; the server-side cooldown is what keeps an outage from becoming
a call per render.

A fee set the API sent with no currency is no longer relabelled in the
store's currency — the grid drops the fixed component rather than
stating an amount in a currency the API never named.

A scope with no stored API key is answered without a call: there is
nothing to ask with.

Subject: [PATCH 652/885] TWO-25669/chore: state the rule instead of quoting
 the source

Two docblocks reproduced an internal ruling word for word; both now
state the resolver's own rule and cite TWO-25554. Also re-points one
missed citation at TWO-25326, corrects a Jest title to the behaviour
its assertions pin, and reflows two blocks to their file's width.

Subject: [PATCH 653/885] fix: a fee set with no currency is not an answer
 (ABN-512)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Review round findings.

A 200 carrying fees but no currency was cached and drawn: a percentage
of zero rendered as an empty span, which is the "this term carries no
fee" reading the ticket exists to remove. It is a failed fetch now, so
it neither replaces the last retrieved set nor reaches the screen.

A scope with no API key saved gets its own category, so the screen names
that rather than reporting an outage, and the screen stops asking — the
answer cannot change until a key is saved.

Only the newest fee request may paint, so a slow answer landing after a
later one no longer restates figures already replaced.

Subject: [PATCH 654/885] fix: judge both refresh marks on age, and let the
 first miss own its clock (ABN-519)

Review round findings.

The absent-on-read mark was rewritten on every failed read, so it was
never old enough for the health surface to act on and the dead-schedule
diagnosis was lost. The first such read now owns the timestamp.

The health row judges both marks on age and no longer outranks a stamp
that answered the miss, so a healthy install whose scheduled fetch
merely failed twice is not reported as a dead schedule.

Subject: [PATCH 656/885] ABN-522: deprecate the custom payment term to
 remove-only

The field renders only for a merchant who already stores a value, offers keep-or-remove
instead of free entry, and refuses any other write. A save that leaves it alone no longer
blanks an offered-term match nor aborts the whole section on an unoffered one.

Subject: [PATCH 657/885] ABN-522: fold a legacy custom term into the standard
 term it names

A stored value the merchant record offers as a standard term ticks that term, clears this
field and hides the row, restoring the behaviour the deprecation removed. An unresolvable
offered set matches nothing, so an outage cannot delete a migration value.

One normalisation now governs the gate, the render and every backend model: a zero reads as
blank, leading zeros normalise to the same term, and anything else stored stays visible and
blocks the save until it is removed.

Subject: [PATCH 658/885] ABN-522: land the approved hint wording for the
 legacy custom term

Both branches keep their End-of-Month and standard distinction and now name the stored term
through the %1 placeholder, pointing the merchant at Remove or at the payment terms above.

Translations for all three shipped locales are machine-generated and unreviewed.

Subject: [PATCH 659/885] fix: let a stopped schedule show on a store with no
 traffic (ABN-519)

Review round findings.

The stand-in mark was rewritten on every stand-in, and stand-ins recur
once an hour, so it never aged past the threshold the health row judges
it by. The first stand-in owns the clock, as the absent mark already
does.

A store with no traffic never stands in at all, so the health row now
also judges the success stamp's own age: a schedule that is running
replaces a record long before that bound. Both marks get two ticks of
grace rather than one, so ordinary cron jitter is not a diagnosis.

Subject: [PATCH 660/885] fix: name a term the answer did not price (ABN-512)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

An answer covering only some of the requested terms left the rest with
an empty span, which reads as "this term carries no fee" — the misread
the ticket exists to remove. Such a term is now named as having no
figure, and the terms that were priced still show their fees.

The dead empty-currency render branch is gone: a set with no currency is
refused server-side rather than drawn.

Subject: [PATCH 661/885] ABN-522: pair the fold-in clear with the tick that
 replaces it (F1, F2)

The tick is the sibling checkboxes field's write, and an inherit-ticked or env.php-locked
sibling never reaches its own beforeSave, so clearing here would drop the term with nothing
to take it. The clear now requires a posted sibling.

The notice moves to the post-commit callback, which a rollback never reaches, so a later
field's refusal can no longer leave the merchant told of a clearing that did not land.

From cd19e1a53badd447e4712126cf185da767fdf5ff Mon Sep 17 00:00:00 2001

Subject: [PATCH 662/885] ABN-522: route every reader of the custom term
 through one normalisation (F3, F9)

The config repository and the surcharge grid cast the stored row and the admin scripts parsed
it, so '1e2' reached the buyer as a 100-day term and the dropdown as a 1-day one while the
admin refused to save it at all. Both PHP readers now resolve it through StoredTerm, and the
renderer emits that result as data-two-term for the scripts to read.

The admin field's stub escaper follows the real one in escaping brackets, so a test can no
longer assert an attribute literal production never emits.

Subject: [PATCH 663/885] ABN-525: uncovered registry country must not block
 manual company entry
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The country gate disabled the popover's anchor field and refused open(), and
the mode chips live inside the popover — so a buyer in an uncovered country
had no route to manual entry or the sole-trader flow.

The gate now withdraws the search only: the query row and the
registered-company chip go, the panel still opens, and the field never carries
the native disabled flag. The chip row is shown whenever it offers a mode the
buyer is not already in, and open() focuses the first offered chip where the
query row is withdrawn.

Subject: [PATCH 664/885] fix: a cron that runs against a dead API is not a
 cron that stopped (ABN-519)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The health row read a dead schedule off the record's success stamp,
which only moves on a successful fetch — so a scheduled run that ran
hourly and could not reach the API reported the schedule as not running.

The scheduled run now records that it ran, whatever its own fetch did,
and the row judges that. The success stamp answers only where no run
stamp exists at all, which is the store with no traffic the previous
round was for.

Subject: [PATCH 668/885] ABN-522: give the unusable state its own wording, and
 drop the entry it offered (F4, F5)

A value that is not a number of days claimed a term was being offered and never said why the
section would not save. It now has its own hint, ahead of the End-of-Month and standard split,
since an unusable value has no term semantics to qualify.

The mandatory-selection refusal no longer offers to enter a custom term: the field is
remove-only, and the refusal can only fire where no legacy term is stored at all.

Translations for the three shipped locales are machine-generated and unreviewed.

Subject: [PATCH 669/885] ABN-522: point the fee-notice fixture at the
 keep-or-remove control

The custom-term field renders as a select whose term comes from the server-emitted
data-two-term, so a fixture built on a text input never changes the term set the fee request
is keyed on.

Subject: [PATCH 671/885] ABN-525: typing in the field must not queue a
 withdrawn search
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The field's own input handler moved the keystrokes into the query row and
queued a search regardless of the gate — so in an uncovered country the
character vanished into a hidden row and a doomed request went out. The
keystrokes now stay where the buyer put them, with the panel offering manual
entry.

Subject: [PATCH 674/885] ABN-522: decide the sibling write from the inherit
 flag, not the posted value (N1)

The checkboxes template always emits an empty hidden fallback, so an inheriting sibling posts
an empty string rather than nothing and a value-shape test could never tell the two apart. The
clear now applies the same two tests Magento uses to decide whether that field is written at
all: the posted inherit flag, and whether env.php locks it.

Subject: [PATCH 675/885] ABN-522: escape the named stored value, and read the
 edited scope from the request (N2, N3)

Config comment output is rendered raw so this form's help text can carry markup, so the
unusable wording escapes the value it names.

The fold-in marker asked the Data\Form object for the scope, which never carries one and
resolved every scope to default: at store scope the marker came from the default record's
offered set, hiding a row the save would not fold. It now reads the store request param, as
SurchargeGrid::resolveScope() does.

Subject: [PATCH 676/885] ABN-522: read the default-term pre-selection scope
 from the request

The element's form is the fieldset, which carries no scope, so the API-supplied pre-selection
was read from the default merchant record at every scope and a store view was offered terms
its own record may not have.

Subject: [PATCH 677/885] ABN-522: read the checkbox scope from the request,
 not the fieldset

The fieldset carries no scope, so every scope resolved to default: at store scope the
checkboxes rendered the default record's offered set, and the save then refused terms the
merchant could tick.

Subject: [PATCH 678/885] ABN-522: hide the deprecated term row only where the
 save folds it

The marker claimed a fold-in from the offered set alone, so a row the save keeps rendered
hidden and left the merchant no control to remove the value. The env.php lock on the Payment
terms sibling now gates the marker, and the JS composes it with the sibling's live inherit box.

Subject: [PATCH 679/885] ABN-522: refuse an unusable custom term at every
 scope it is in effect

Every field in the payment-terms group binds through config_path, which the
admin form's config-data filter does not match, so each renders with inherit
ticked at store and website scope. An inherit-flagged field is routed to the
delete transaction, where no backend model's beforeSave runs, and the junk
value survived the save untouched at those scopes.

The three catalogue rows are machine translations and unreviewed.

Subject: [PATCH 680/885] ABN-522: suppress the fold-in marker when the
 custom-days field is env-locked

Core skips a field's backend model when that field itself is locked in
env.php, so a lock on the custom-days field left the marker claiming a
fold-in nothing would perform: the row hid, no value moved and no notice
was announced, while the sibling still ticked the matching term.

The two fold-in stubs now match on the queried path and its scope, so a
lock read at the wrong scope no longer reads as a lock.

Subject: [PATCH 681/885] ABN-522: resolve an unresolvable store to the website
 param, as the cited reference does

Both payment-terms field blocks cite SurchargeGrid::resolveScope() as the
statement of their semantics, but wrapped both branches in one try: a store
param that resolves to nothing short-circuited to default and never tried the
website param. Each branch now has its own, so the behaviour matches the
citation.

Subject: [PATCH 683/885] ABN-522: match three test stubs to the framework
 surface they stand in for

Store::getCode() returned null where every real store has a code, so a
scope-code assertion routed through it was vacuous. The admin config Field
stub's setData() indexed by an array key instead of replacing the bag, which
is a fatal on the array call shape core accepts. The element stub's
getHtmlId() dropped the form's id prefix and suffix, so ids under test could
not match the rendered ones.

Nothing asserts against any of the three today, so no test changes
behaviour; the three test form stubs gain the id-prefix accessors the real
Data\Form always carries.

getWebsite() answered with the same record for any argument and was not
recorded, so the website branch of getBaseCurrency() asserted only that some
website answered, not that the scope's own was asked for.

Subject: [PATCH 686/885] ABN-522: refuse the unusable term only where the page
 shows it

The guard fires on one shape: the scope being saved holds no row of its
own, so the field renders inherited and disabled, posts its inherit flag
and no value, and reaches no backend model. The value it refuses over is
the value the page displayed.

A scope holding its own row renders the inherit box unticked and posts
its value, where Model\Config\Backend\PaymentTermsCustomDays refuses it.
A tick there is left to core: it discards the local row for a value this
page never showed, and lands on the shape above, refused on the next
save of it.

The premise the every-scope guard rested on was wrong.
Magento\Config\Model\Config\Structure\Element\Field::getSectionId()
takes its section from the config path, so the form's own extendConfig
call in Magento\Config\Block\System\Config\Form::initFields loads these
rows after all, and the inherit flag is ordinary Magento: ticked only
where the scope carries no row of its own.

Subject: [PATCH 687/885] ABN-522: check only the sibling for the fold-in
 marker again

Revert of db9d880066c9ee9ee37ceae50180915485effb72.

The env.php arm it added could never fire.
Magento\Config\Model\Config\Reader\Source\Deployed\SettingChecker
resolves system/<scope>/<path> out of the deployment config, so the path
it takes has to be a config path; the caller passes the structure path
that field_config carries. So this removes no behaviour, only a loop
that always completed.

The lock stub in the renderer's test keeps matching on scope as well as
path, which the revert would otherwise drop: the scope of the lock query
is what testTheEnvLockIsQueriedAtTheScopeBeingEdited asserts.

Subject: [PATCH 688/885] ABN-533: an upstream outage no longer withholds the
 payment method
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Only a definitive api-key rejection — invalid_key, not_configured — takes
Two off checkout. unreachable, service_error, error and malformed_response
fall through to the never-expiring cached merchant record.

+The availability chain reaches the api-key verification verdict before it reaches

Subject: [PATCH 690/885] ABN-542: remove the surcharge grid's unreachable fee
 fetch

The grid has no fee column and no call site for the fetch that fed one,
so the request path and everything only it read are dead.

Admin fee figures stay on the term chips (payment-terms-config.js), which
is where the staleness and retrieved-at notice lives.

Subject: [PATCH 692/885] ABN-522: ask SettingChecker for the sibling's env.php
 lock by config path
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Both remaining callers passed the structure path two_payment/payment_terms/payment_terms.
SettingChecker::isReadOnly resolves system/<scope>/<code>/<path> out of the deployment
config, keyed by config path, so neither query could ever return true and both branches
were dead. Plugin/Config/RefuseUnusableCustomTerm already asked by config path; the block
renderer and the backend model now resolve the sibling's declared config path through
Magento\Config\Model\Config\Structure and ask under that.

Making them live changes an env.php-locked sibling from a silent loss to a visible one:
the marker is now withheld, so the deprecated row renders instead of hiding, and the save
keeps the value instead of clearing it. Previously the row hid, the value was cleared and
the fold-in was announced, while the tick it folded into sat under an env.php value that
overrides it — so the term left the offered set. Neither half refuses a save, so no
merchant is left without an exit; Remove is still on the field.

Corrects two false docblock claims with them. Core's own env.php skip in
Config::_processGroup asks isReadOnly($groupPath . '/' . $fieldId), also a structure path,
so it never fires for a config_path-bound field. And a field posting an inherit flag goes
to the delete transaction only where the scope holds a row of its own; with no row it
enters neither transaction.

An earlier commit on this branch described the symptom of the missing lock check as the
sibling still ticking the matching term. That is wrong and is not repeated here: an
env.php-locked sibling still posts, so the tick is recorded, but env.php overrides it.

RefuseUnusableCustomTerm::scope() treated any non-empty getStore() as store scope.
Magento\Config\Model\Config::retrieveScope() switches on PHP truthiness, so "0" falls
through to default there, and Plugin/Config/Structure/HideFieldsUnlessConfigured reads the
param the same way. The guard now agrees with both, so a save the pipeline runs at default
scope is no longer gated on a store view's inherited value. Not reachable from the admin
store switcher, so the change is the truthiness test and nothing else.

The test's scope fixture stops claiming a website for a param that names no scope: it now
answers with one nothing can match, so a read the plugin should never make fails instead of
passing for the website's.

Subject: [PATCH 694/885] ABN-522: cover a website holding its own custom-term
 row

UnusableTermRefusedWhereItShowsTest exercised the own-row exemption only at store scope, so
holdsItsOwnRow() querying the loader at a hardcoded scope would have gone unnoticed at
website scope. Hardcoding 'stores' in that query now fails the new row.

 unitemized fee

A third-party extension's fee was refundable only in proportion to the
items on the credit memo, with no way to refund part of it or none of it.

Subject: [PATCH 697/885] feat(ABN-492): put the unitemized fee refund on the
 credit-memo form

value the collector had already deferred; saving the untouched form posted it
as an explicit instruction, turning a silently omitted fee into a refusal that
blocked the credit memo.

The editable row was offered, and a typed value stamped, on any order with an
unitemized residual — including one paid by another method, where the
collector ignores it and the stamped value still persists to the memo's own
column. The payment-method gate now has one definition, on the resolver.

Subject: [PATCH 701/885] ABN-531: judge the custom term against the row the
 form rendered

The admin config form reads its values from the config table, while the
save-time guard read the same path back through the config cache. Where
the two disagreed the only postable value was refused and the whole
section save aborted.

Subject: [PATCH 702/885] ABN-533: the checkout-config subtree withholds only
 on a rejected key

Model/Ui/ConfigProvider::getConfig() still returned [] for every non-ok
verdict. That emptiness is a second withhold in all but name - the Luma
company-search widget and the payment renderer both mount behind the
subtree - so an outage left the method offered by isAvailable() with no
config for its renderer to mount against.

Subject: [PATCH 703/885] ABN-533: the order-intent and lookup routes stop
 refusing on a blip

Emitting the config subtree during an outage made two routes reachable that
were not before, and both still gated on any non-ok verdict: order-intent
answered 503 "not available right now" on a shop whose key is fine, and the
registry proxy dropped merchant attribution. Both now ask
isDefinitiveFailure(), and the merchant identity they relay comes from the
never-expiring record rather than the verdict, which carries one only on a
success.

Subject: [PATCH 704/885] ABN-533: review round - gate before the identity
 read, scope it to the quote

Review round 2 on this branch. The definitive-failure gate ran after an
identity read that can cost two 10-second fetches on a shop with no cached
record, and both webapi routes judged the current store's verdict against the
quote store's record. The verdict-then-record normalisation is now one shared
SettingsProvider::identityFrom().

Subject: [PATCH 705/885] ABN-533: review round - one normaliser, and it cannot
 fatal on a bad cache

Review round 3 on this branch. identityFrom() is an instance method taking
mixed: a cached verdict whose merchant is not an array would have thrown a
TypeError out of an anonymous REST route under strict_types. The checkout
config subtree now routes through it too, so it ships identity in one shape
rather than the whole verify_api_key body on success and {id, short_name} on
a fall-through.

Subject: [PATCH 706/885] ABN-533: drop an is_array guard no test can kill

The untyped parameter is what stops the TypeError; a scalar offset read
already coalesces to null, so the guard was unreachable in practice and
nothing could fail if it went.

Subject: [PATCH 708/885] ABN-544: no default term is invented when the
 merchant offers none

The default-term resolver ended in a hardcoded 30, so an account offering
no term still produced a day count the buyer could be priced and placed on.
It now returns null, and each caller reads that as no selection rather than
substituting one.

Subject: [PATCH 712/885] fix(ABN-497): enforce the surcharge tax treatment on
 every brand's admin form
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The save-time guard was wired only in etc/adminhtml/system.xml. An overlay
install renders exclusively the sections synthesised from
brand_form_template.xml (HidePaymentSection hides the static Two ones), and the
template omitted the backend_model on Surcharge method — the field that is
posted on every section save — so no brand enforced the invariant at all.

Also refuse a save that leaves a stored never-taxed treatment in place without
replacing it: a blank submission used to overwrite it with an empty string,
silently changing how the surcharge is taxed and erasing the state the field's
own warning reads.

BrandFormModelWiringParityTest compares source/backend/frontend model wiring
across both forms for every shared section, which is also what surfaced the
missing DefaultPaymentTerm renderer on brand forms.

Content-Transfer-Encoding: 8bit

A brand suppressing `surcharge_tax_class` (brand.xml `suppressed_fields`) or a
scope inheriting it does not post the field, so demanding the stored sentinel be
replaced *in this save* made the whole payment section unsaveable with no
control on the page to fix it — for exactly the population this change targets,
since no brand had the guard before. Such a save cannot overwrite the stored
value either, so it is now let through.

Also: the stored-treatment refusal runs after the submitted-value one, so
re-submitting the sentinel verbatim is attributed to what was submitted; the
message no longer claims the value lives at "this store" when inheritance means
it may sit at a parent scope; and the parity test's field walk is
depth-agnostic and fails legibly on an unprefixed section id.

From a2ea190967385f98ea55992204f703260342a07b Mon Sep 17 00:00:00 2001
From: Douglas Lindsay <dlindsay@two.inc>
Date: Wed, 9 Sep 2026 18:54:58 +0100
Subject: [PATCH 714/885] fix: read the merchant record at the scope the admin
 form is editing (ABN-530)

The API key is website-scoped, but every payment-term and surcharge admin
surface resolved a store id only, so a website-scoped edit was judged against
the default scope's key and therefore another merchant's offerable terms. A
website-scoped custom term folded into a checkbox it was never offered under,
and the buyer-facing read then dropped it.

Config reads now take the (scope id, scope type) pair Model/Config/AdminScope
resolves, threaded through SettingsProvider, RecordProvider, OfferedTermsGuard,
ApiKeyStatus and FeeRatesProvider. Two surfaces resolved a website through a
representative child store, whose own key override decided the answer; both
now ask at website scope.

Subject: [PATCH 715/885] fix: verify the API key panel at its form's scope,
 keep the FX store id (ABN-530)

Review round 1: the api-key panel refreshed the default scope's verdict on
every scope's form, and the fixed-cap conversion lost the store id the FX
lookup takes. The conversion path had no test, which is why only PHPStan
caught it; it is now pinned at all three scopes.

Subject: [PATCH 716/885] test: align the api-key status doubles with the scope
 parameter (ABN-530)

fataled on the widened signature.

Subject: [PATCH 717/885] docs(comments): cite the requirement, not a person

A class docblock attributed a refund requirement to a named individual and a
CI comment attributed a job's scope to a named reviewer. Both now state the
behaviour, with the ticket as the citation where one exists. No behaviour or
test changes.

Subject: [PATCH 720/885] ABN-518: report the scope's own verdict, both minimum
 floors, and the core country gate

Review round 1 on this PR found the checkout-visibility row reporting the
default scope's verdict on a store-view config page, claiming "shown" while
core's own allowlist was restricted to no country, and naming only the
platform minimum when the merchant's own floor is higher. The row now
resolves the scope from the request, judges both country gates separately,
and names every floor that binds.

Subject: [PATCH 721/885] ABN-518: distinguish an unreadable country list,
 collapse floors that share a currency, and never fatal on a stale scope param

Review round 2 on this PR found a malformed supported-countries payload
reported as a deliberate account restriction, two floors in the same currency
and basis both named when only the higher binds, an unresolvable scope param
taking the whole configuration page down, and the scope resolution itself
covered only by a test double that overrode it. The transient API-key row is
also no longer painted red, and the withholding log is guarded once per
request.

Subject: [PATCH 723/885] ABN-518: drop the transient-verdict row now ABN-533
 has landed
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

A transient api-key verdict no longer withholds anywhere, so the row must not
report it as a checkout state at all — it falls through to the cached record
and reads as shown. Removes the notice, its now-dead catalogue rows and the
tri-state colour that existed only to paint it. The row's verdict read also
judges the page's own scope, and the two country-gate field names quote each
locale's own translation of those labels.

Subject: [PATCH 724/885] ABN-518: restore the transient-verdict row, and name
 an unknown floor
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

ABN-533's fall-through has not landed in this repo — ApiKeyStatus::isVerified()
is still status === OK, and both Two::isAvailable() and ConfigProvider withhold
on any non-OK verdict — so a row that reads "shown at checkout" for a
transient one states a falsehood. The row is back, worded to claim neither a
withholding nor a showing.

Also: a platform floor that has never been fetched reads as unknown rather
than absent; the checkout config subtree's log line names its own surface and
verdict rather than duplicating the payment method's; and the country-gate
reason matches its siblings' voice.

Subject: [PATCH 726/885] ABN-518: say the transient verdict withholds, and
 stop suppressing a known floor
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

A transient api-key verdict does withhold today — isVerified() is status ===
OK — so the row names it as the reason rather than declining to answer. The
arm is marked for deletion with ABN-533's fall-through, which owns that gate.

Also: a cold profile no longer suppresses the merchant's own configured floor,
which is a local admin value and fully known; and a configured buyer surcharge
is named as a currency constraint, since whether the fee can be priced depends
on the basket's currency.

Subject: [PATCH 727/885] ABN-518: ABN-533 has landed, so the transient and
 empty-term-set arms come out

The gate now refuses only a definitive api-key failure, and an empty merchant
term set withholds nothing, so a notice for either state would read as a live
feature. Both arms are removed along with their catalogue rows, and the row
falls through to "Shown at checkout" for a transient verdict.

Subject: [PATCH 728/885] ABN-518: judge the whole panel at the page's scope,
 and name the buyer allowlist
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Review round found the panel's own API-key row reading the default scope's
verdict beside a row that judged the page's, so a store-view page could show
"API key: Verified" next to "the API key was rejected". The whole panel now
resolves one scope. A merchant allowlist is named as a constraint the way the
minimum floors are — every buyer outside it is withheld and no local field
says so. At default scope the base currency comes from the default store view
rather than the admin store, whose currency is not the storefront's.

The withholding log follows ABN-533's own predicate, so only a definitive
verdict is recorded; the four transient categories are covered by a test that
asserts nothing is logged.

Subject: [PATCH 729/885] ABN-518: resolve the verdict once, and repair the
 edit residue

The panel resolves the api-key verdict once and hands it to the row rather
than reading it twice per render, the two stacked docblocks left by an earlier
commit are separated onto their own tests, and the log test is named for the
two definitive verdicts it actually covers.

Subject: [PATCH 730/885] ABN-518: name both country gates together, and scope
 the whole panel
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Core's own allowed-countries list and the merchant's account allowlist both
bound who is offered the method, so the row names their intersection — and
says plainly when the two do not overlap, which neither field says alone.

The panel's environment and SSL rows also judge the page's scope, so a
store-view page can no longer name one environment beside a row that judged
another. The merchant floor is the only clause needing a store, so a scope
with no resolvable default store keeps the rest.

Subject: [PATCH 731/885] ABN-518: repair the edit residue round 10 found

The docblock for the unknown-floor test sat above a different test, one
reason read capitalised beside six lowercase siblings, and a duplicate mock
stub sat under the expectation that already satisfied the call.

Subject: [PATCH 732/885] ABN-546: withhold the payment method when the buyer
 fee quote fails

A fee quote the pricing endpoint cannot answer is recorded as a
short-lived marker, and isAvailable() reads it to withhold this method
at checkout. The admin settings page is untouched: its fee preview
reads merchant rates, not the buyer quote.

+only its definitive-rejection categories withhold (ABN-533). Do not widen it
+back to every failure category, and do not add a further gate that withholds
+because a call to Two failed; both are defects the rule exists to stop coming
+back. The buyer fee quote is the one named exception (ABN-546): a term whose fee
+cannot be priced cannot be charged, so checkout withholds while the admin
+settings page only logs — its fee preview reads merchant rates through
+`Service\Merchant\FeeRatesProvider`, never the buyer quote, so a merchant is
+never locked out of the settings they need to fix it.
+
+`SurchargeCalculator` records that failure as a marker under a 60-second TTL, and
+`isAvailable()` reads the marker only — never a live quote, because it runs on
+every render of the payment-method list. The marker is keyed on term, currency
+and store, so one misconfigured term withholds nothing from a checkout charging
+another, and a recovered pricing endpoint restores the method within the minute
+with no retry from the gate. A quote of zero, an empty basket, a term with no
+surcharge configured and surcharge type `none` are all successes, and withhold
+nothing.

Subject: [PATCH 733/885] ABN-546: price the charged term in the availability
 gate

The gate quotes the fee for the term the checkout would be charged for,
on the request that renders the payment-method list, and withholds the
method when that quote is refused. Guards concede without a call when
there is no cart to price, so no adminhtml or cron path quotes anything.

ChargedTermResolver is now the single source of the charged term, shared
with the totals collector so the two cannot disagree.

+back. The buyer fee quote is the one named exception (ABN-546): a term whose
+fee cannot be priced cannot be charged, so the gate prices it rather than wait
+to be told. It resolves the charged term — the buyer's own selection, else the
+configured default, through `Service\Order\ChargedTermResolver`, the same
+resolver the totals collector uses so the two can never disagree — and asks
+`SurchargeCalculator::calculate()` for that one term on the cart being judged.
+A refusal withholds the method for that request and that cart only, and the
+next request re-asks, so recovery needs no expiry and one buyer's refused quote
+cannot reach another's checkout.
+
+Four guards run before any call and concede the method without one: no
+surcharge configured, no cart carrying items and a positive total, no currency,
+no term offered. They are also why no adminhtml or cron path ever prices
+anything — none of them presents a cart to price. Cost is bounded at one
+pricing call per render: `calculate()` memoizes per request and caches a
+success for 300 seconds keyed on the request body, so the totals collector and
+the term-chip endpoints reuse the same quote.
+
+The admin settings page is untouched: its fee preview reads merchant rates
+through `Service\Merchant\FeeRatesProvider`, never the buyer quote, so a
+merchant is never locked out of the settings needed to fix this.

From a48001a0639b30aeb259417fe04890ffbc7c90cd Mon Sep 17 00:00:00 2001
From: Douglas Lindsay <dlindsay@two.inc>

Subject: [PATCH 734/885] ABN-546: bound, broaden and scope the render-path fee
 quote
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The gate moves into its own service. Its pricing call carries a short
timeout so a hanging endpoint cannot stall the payment step, catches
broadly so a malformed response costs the method and not the page,
prices the fee-exclusive total the collector and the chip endpoints
price, and concedes without a call in the adminhtml area — Magento
evaluates payment availability during admin order create, and
canUseInternal() is not consulted first.

ChargedTermResolver drops a selection the merchant has withdrawn,
which placement would refuse anyway.

 because a call to Two failed; both are defects the rule exists to stop coming
 back. The buyer fee quote is the one named exception (ABN-546): a term whose
-fee cannot be priced cannot be charged, so the gate prices it rather than wait
-to be told. It resolves the charged term — the buyer's own selection, else the
-configured default, through `Service\Order\ChargedTermResolver`, the same
-resolver the totals collector uses so the two can never disagree — and asks
-`SurchargeCalculator::calculate()` for that one term on the cart being judged.
-A refusal withholds the method for that request and that cart only, and the
-next request re-asks, so recovery needs no expiry and one buyer's refused quote
-cannot reach another's checkout.
-
-Four guards run before any call and concede the method without one: no
-surcharge configured, no cart carrying items and a positive total, no currency,
-no term offered. They are also why no adminhtml or cron path ever prices
-anything — none of them presents a cart to price. Cost is bounded at one
-pricing call per render: `calculate()` memoizes per request and caches a
-success for 300 seconds keyed on the request body, so the totals collector and
-the term-chip endpoints reuse the same quote.

+
+The gate resolves the charged term through `Service\Order\ChargedTermResolver`,

+selection the merchant has since withdrawn falls back to the default rather
+than pricing a term the order would be refused for at placement. It prices the

+already on the quote is neither compounded nor a cache miss against their
+quote. The call carries its own short timeout instead of the adapter's default,
+because a hanging endpoint on a render path would otherwise stall the payment
+step. A refusal — including a malformed response, which is caught as broadly
+as the collector catches it — withholds the method for that request and that
+cart only; the next request re-asks, so recovery needs no expiry and one
+buyer's refused quote cannot reach another's checkout.
+
+Guards run before any call and concede the method without one: the adminhtml
+area, no surcharge configured, no cart carrying items and a positive
+fee-exclusive total, no currency, no term offered. The area guard is what keeps
+admin order create from pricing: Magento evaluates payment availability there
+against a quote, and `canUseInternal()` is not consulted first, so without it
+an admin session's term would be quoted.

+The admin settings page prices nothing either way: its fee preview reads

Subject: [PATCH 735/885] ABN-546: record why a withheld fee quote failed, and
 pin the gate's own guards

The gate error-logs the exception class and message; nothing downstream
records a corrupt cached quote or a failing session read, and the
withhold is invisible to buyer and merchant alike.

Quote attempts are now counted at the calculator, not only at the
adapter: calculate() short-circuits some inputs itself, so an
adapter-only count credited the gate with the calculator's guard.

Subject: [PATCH 736/885] ABN-546: set the render-path fee-quote timeout
 ceiling to 30 seconds

The test reads the adapter default by reflection and asserts the
override is bounded strictly under it, so neither number is restated.

Subject: [PATCH 738/885] ABN-546: one surcharge-pricing ceiling for every path

SurchargeCalculator bounds the pricing call itself, so the availability
gate, the totals collector and the term-chip endpoints share one
ceiling instead of two kept equal by hand. The gate can no longer
refuse a fee the charging path would have priced.

Subject: [PATCH 739/885] fix: show the configured sole-trader failure message
 to the buyer

The failure copy published in the checkout config, which goes through the
translation catalogues and can be replaced by a brand overlay, was assigned to
the payment renderer and never read. What a buyer actually saw was a separate
string held in the flow model, translated client-side and beyond the reach of an
overlay.

The flow model now reads the configured value the same way it already reads the
other checkout config values it needs, and the dead assignment on the renderer
is gone.

Subject: [PATCH 741/885] docs: scrub remaining internal work-split labels from

milestone labels that the first pass missed, plus a few comment blocks
left with ragged wrapping.

Subject: [PATCH 743/885] docs: state the admin section scheme by its real
 labels, and correct the count
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The synthesiser docblock listed six canonical sections including a
_search section that no longer exists — it was folded into
_checkout_fields, as the template header already records. The lettered
A-F ordering was an internal scheme that never appeared in the admin UI.

Subject: [PATCH 744/885] docs: drop the lettered section markers and the
 remaining A-E scheme labels

The section markers in system.xml and the brand form template carried an
A-E ordering that never appeared in the admin UI, and four other files
still cited the regroup by those letters.

Subject: [PATCH 745/885] ABN-548: prefer a 30-day default payment term when
 the merchant offers it

The checkout's preselected payment term resolves the admin's stored default,
then the merchant record's own default term, and previously fell straight to
the shortest offered term. PrestaShop instead prefers 30 net days at that
point, which is the behaviour the other platforms are being aligned on.

With an offered set of 7 and 30 days and no stored default, checkout now
preselects 30 where it preselected 7.

The empty-set rule from ABN-544 is untouched: a merchant offering no term
still resolves to no default, and the preference only applies when 30 is
genuinely in the offered set.

Subject: [PATCH 746/885] ABN-548: review round 1 - the admin default-term
 field follows the same order

The resolver's new preference was reachable only on a store nobody had ever
saved. The admin default-term select rebuilds its options from the ticked
terms and, when that drops the current selection, synthesised the lowest one;
that select posts on the next save, after which the stored default wins
permanently and the preference could never fire again on that store. The same
select also read as the lowest whenever the stored term had no option to
select, because the DOM cannot express an unset value.

The field now pre-selects, and its JS falls back to, the order the checkout
resolves: the merchant's own default term, then 30, then the lowest offered
term. The pre-selection also applies when the stored term is no longer
offered, not only when nothing is stored.

Test coverage for the vacuous case the review found: the offered set 30, 60
and 90 has 30 as both the preference and the shortest term, so it could not
distinguish the two rules.

Subject: [PATCH 747/885] ABN-548: the admin default-term field offers
 Automatic instead of a guess

The field's select carried only day counts, so a scope with nothing stored,
or a stored term the merchant had withdrawn, rendered as whichever term the
browser showed first and posted it on the next save. From then on the stored
default was the resolver's first step and the merchant's own default term, the
30-day preference and the shortest-term terminal were all unreachable.

The select's first option is now Automatic, an empty value, which is what
etc/config.xml has always stored for "the admin never chose". Nothing
synthesises a day count on the admin's behalf any more: the pre-selecting
field renderer is deleted and its JS only keeps a selection that is still
offered, so a withdrawn term reads as Automatic.

This is the arrangement PrestaShop already ships, and it is what makes the
resolution order in getDefaultPaymentTerm() reachable on a configured store
rather than only on a never-saved one.

Subject: [PATCH 748/885] ABN-548: the admin surfaces that name the default
 term resolve it

With Automatic selected the field carries no day count, and two admin surfaces
were reading it as one. The surcharge grid's differential mode disables and
zeroes the row it prices against by comparing each row against that value, so
it disabled nothing and left the buyer's baseline term editable; the
differential option's own label kept naming whatever term it had last seen.

Both now apply the resolver's order instead. SurchargeGrid resolves it
server-side at the scope being edited, and Two_Gateway/js/default-term is the
one browser-side copy of the order, shared by the grid and the label, fed the
merchant's own default term through a data attribute on the checkboxes
container. The preferred-term constant moves to the config interface, where the
module's shared constants live.

Also removes two comments that described the deleted field renderer.

Subject: [PATCH 749/885] ABN-548: review round 4 - the admin's copy of the
 order intersects too
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The browser-side resolver was handed the ticked terms plus the legacy custom
day, and the checkout intersects that with the merchant's own offered set. A
custom day the merchant's record does not offer therefore resolved in the admin
and nowhere else: differential mode disabled and zeroed that row while the
term the buyer is actually priced against kept its fee and posted it.

The intersection now lives in the resolver itself, fed the rendered checkbox
values, which are one per offered term.

Also adds the two tests the round found missing — the grid's own four-step
resolution and its scope, and which row differential mode disables with the
field on Automatic — and says what Automatic does in the field's own comment.

Subject: [PATCH 750/885] fix: ABN-561 return focus to the company field when
 the signup closes

Opening the hosted sole-trader signup blurs whatever held focus, so a
manual close with nothing captured left the buyer on the document body
with no keyboard position in the checkout.

Abandoning the signup now hands focus back to the company field, after the
re-render that re-points the panel at the live field, and only where focus
is still unplaced: the same close fires when the buyer focuses another
control, and taking that focus back would interrupt whatever they moved to.
The panel restores focus without changing its own open state, which takes
cancelling the pending focus-out close because the field sits outside the
panel node.

Subject: [PATCH 751/885] fix: ABN-550 refuse placement on a payment term the
 server has not confirmed

A chip click set the selection locally and left the order summary to a
/select-term round trip that had no failure path, no sequence guard and
nothing comparing the result against the selection. Where the summary kept
the previous term's fee, the buyer was shown one total and the order was
composed on the selected term at another.

The model now tracks the term a /select-term response has confirmed the
server priced the quote on, and reconciliation is that term matching the
chips with no change in flight. Placement is refused while it does not
match, on the Place Order button's own binding and again at the click. A
response the server did not take reverts the chips and reports the failure;
a superseded response is discarded rather than written into the summary.

+## The selected term must be CONFIRMED before submit

+The order is composed on the term the chips show as selected, so a selection
+the server has not confirmed it priced the quote on can be charged against a
+total the summary never showed (ABN-550). `surchargeModel.isTermReconciled()`
+is the whole invariant — `confirmedTerm === selectedTerm() && !isUpdating()` —
+and `confirmedTerm` moves only when a `/select-term` response actually carries
+the totals it re-collected.
+
+It gates placement twice: `isPlaceOrderEnabled()`, so the button is disabled
+rather than only answering a click, and `placeOrder()` as the belt.
+
+**Do not gate on the chip fees instead.** Comparing the summary's
+`two_surcharge` value against the chip map looks stronger and is weaker: the
+map is documented above as lagging a `/totals-information` transition by one
+step, and `loadFees()`'s own snapshot dedup can then decline to refresh it — so
+a numeric comparison can refuse a settled checkout permanently, behind a
+message that says it is still updating.
+
+`/select-term` carries a sequence guard of its own, as `loadFees()` does. Two
+chip clicks whose responses land out of order would otherwise write the
+superseded term's segments into the summary and confirm a term nobody selected.
+
+A `/select-term` the server did not take reverts the chips to the confirmed
+term and says so. Reverted rather than left standing, because re-clicking the

Subject: [PATCH 752/885] fix: ABN-550 keep the session term unmoved when
 select-term fails

The endpoint wrote the buyer's new term into the checkout session before
collecting totals, saving the quote and repricing the terms. A failure
after that point answered the client with an error - which reverts the
chips - while the server kept the new term, so the surcharge the order
was composed and priced on no longer matched the term on screen.

The write is now staged: the previous term is restored if anything below
it throws, and the quote is repriced back whenever it had already been
saved on the staged term.

Subject: [PATCH 753/885] fix: ABN-550 treat a select-term 200 without totals
 as a refusal

A 200 that carried no re-collected total segments left the selection
standing with nothing confirming it, so placement stayed refused behind
no message, and re-clicking the chip that already looked selected was a
no-op the buyer could not recover from.

Such a response now takes the same revert path as a failed call.

Subject: [PATCH 754/885] test: ABN-550 answer select-term with the segments it
 always returns

The display-mode case answered the endpoint with a payload carrying no
total segments, which the model now treats as a response it cannot
confirm a term from.

Subject: [PATCH 756/885] fix: ABN-561 do not reclaim focus a popup handover
 has placed

Handing the signup popup over to another capture launches that capture's
signup, and the launch blurs the chip it was fired from. The abandoning
capture's close watcher then polled 300ms later, read focus as unplaced
and took it to its own company field, killing the signup the buyer had
just started.

The handover states itself when it fires the other chip, and the close
watcher passes that on, so the two cases are no longer told apart by an
activeElement test that cannot distinguish them.

Subject: [PATCH 757/885] fix: ABN-550 reprice back whenever the staged save
 may have persisted

A save that throws can still have written, so the rollback condition was
set from the wrong side of it. A restore that fails in turn leaves the
quote pricing a term the session no longer holds, which is now logged
rather than swallowed.

Subject: [PATCH 758/885] fix: ABN-550 close four ways the reconciliation gate
 could still be wrong

Reviewed over the whole change rather than the last fix, which turned up
four defects in one region of the model, all in the placement gate's own
inputs:

- Two select-term calls could overlap. The server serialises them on the
  session lock and can take them in the opposite order to the one they
  were sent in, so confirming from the client's send order could leave
  the session holding a term the chips had discarded as superseded - the
  ABN-550 shape again, inside the fix. Only one call is now in flight; a
  chip clicked during one is held and sent when it settles.
- The call had no timeout, so a hung request held the updating flag for
  the rest of the session and with it the Place Order button disabled,
  with no message and nothing to click.
- The confirmed term was a plain variable, so the button binding only
  re-evaluated because the updating flag happened to change afterwards.
  It is now observable and the gate depends on it.
- An empty segment set passed the truthiness check, confirming the term
  and blanking every summary row.

A totals emission arriving during a chip click was also dropped and never
re-evaluated, because the snapshot the response wrote deduped the fetch it
needed; the module's own write-back is excluded from that so a settled
click still does not refetch what it just received.

Subject: [PATCH 759/885] fix: itemise the surcharge on every customer order
 and invoice surface
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Magento's guest sales layout handles inherit nothing from their signed-in
siblings — each declares its own totals block — so a surface the module
does not name in its own layout file renders the grand total with the
surcharge folded in but no row accounting for it. The credit memo was the
only family covered on all four surfaces, which is why it itemised
correctly while the order and invoice views did not.

`sales_order_invoice_view` is an adminhtml-only handle name, so the file
under it was never loaded on the storefront; the frontend invoice handle
is `sales_order_invoice`.

Adds the missing guest and print handles for the order and invoice
families and renames the dead one. The surcharge row attaches to core's
`order_totals` / `invoice_totals` block, as it already did for the credit
memo. "Other charges" stays credit-memo-only, matching its collector.

Subject: [PATCH 760/885] fix: ABN-561 judge the reclaim on state the close
 cannot have changed

Reviewed over the whole change rather than the last fix, which turned up
three defects around the focus guard:

- The guard was read after returning to registered mode, which can remount
  the panel and so unplace focus the buyer had put somewhere themselves -
  inverting the rule that a close the buyer caused keeps their focus.
- The handover flag was set for any handover, including one whose chip
  opened no popup and so blurred nothing; it now records whether focus was
  actually taken off the chip, so a handover that opened nothing no longer
  suppresses the reclaim.
- Restoring focus left the panel's reopen guard latched if focus() threw.

Also merges the two stacked doc blocks on abandonSoleTrader into one and
moves the case descriptions to the end of both tables.

+**A handover is told apart by a flag, not by the close watcher reading focus.**
+Handing the popup over to another capture launches that capture's signup, and
+that launch blurs its own chip — so the abandoning capture's close watcher,
+polling 300ms later, sees exactly the unplaced focus it reads as its own to
+reclaim. The handover therefore records whether the other capture's launch
+actually took focus off the chip, and the close watcher passes that on as
+`returnFocus`. A handover whose chip opened nothing leaves the buyer on that
+chip and is not suppressed.
+
+The reclaim decision is read BEFORE returning to registered mode, which can
+remount the panel and so unplace focus the buyer had put somewhere themselves.
 
 The panel's own restore leaves its open state alone, which takes cancelling the
 pending focus-out close, since the company field sits outside the panel node and

Subject: [PATCH 761/885] fix: stop an irrelevant hidden admin field refusing
 the save in silence
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Magento's admin validation widget drops `:hidden` from jQuery-validate's
ignore list, so a field the payment-terms screen hides as irrelevant is
still validated and still aborts the submit. Its explanation is rendered
inside the hidden row, focus on it is swallowed, and the surrounding
handler cannot reveal it — so the save reports neither success nor
failure, and a stale `aria-invalid` outlives the field the merchant can
no longer reach.

A zero surcharge cap left behind in Percentage mode therefore blocked
every later save of the section, including the switch to "No surcharge
applied" that makes the cap moot. A cap stored as zero did the same on
every page load under a fee type with no cap column.

Hides now scope validation to what is on screen, via the `ignore-validate`
class the widget does honour, and clear the unreachable refusal. Where the
field is visible the refusal is unchanged: a zero cap is still rejected,
with its explanation next to the field. Unlike core's dependence
controller these rows are never disabled, so they keep posting and stored
values survive the save.

Applies to the unbranded settings section and each synthesised brand
section alike: both admin scripts already derive the section prefix from
the rendered form rather than assuming one.

Subject: [PATCH 762/885] fix: translate the company picker on the storefront
 checkouts
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The picker's search prompt, mode chips and unavailable notice live in
framework-free modules that ask their host to translate a phrase by name.
Magento builds the storefront's JS dictionary by scanning source for
literal `$t()` calls, so a phrase written only as a name passed across
that seam never enters the dictionary: the lookup then finds nothing and
returns the English source, on a checkout whose address fields and payment
copy are correctly translated, with no error and no log line. The
catalogue rows existed all along.

The Hyvä integration is unaffected because it localises server-side and
never reads that dictionary.

The Magento adapter now answers those phrases from a dictionary that
spells each one out, which is both what the buyer sees and what the
scanner can harvest. A unit test ties the two together: every phrase
requested across the seam must be spelled out in the adapter and must
carry a translation in each shipped locale, so a new one cannot be added
in English only.

ABN-555

Subject: [PATCH 763/885] fix: ABN-550 stop a throwing totals subscriber
 latching the gate

Applying a settled response wrote the summary through Magento's totals
observable with nothing catching a subscriber that throws. jQuery fires
done callbacks without a try, so one throwing order-summary subscriber
skipped the always handler entirely - leaving the updating flag set, the
Place Order button disabled for the life of the page behind "still being
applied", and every later totals emission discarded as this module's own
write-back. Nothing recovered it short of a reload.

The response write is now guarded, and the self-emission flag released in
a finally. A rejected response takes the same revert path as a refused
call, so placement is refused rather than charged.

Also holds the one-call-in-flight rule inside recalculateTotals itself
rather than in its caller, which makes the response sequence guard
unreachable, so it and its own test case are deleted; and drops two stub
methods no test uses.

+The response is applied inside a `try`. A totals subscriber throwing out of
+`setTotals` would otherwise abort the rest of jQuery's callback chain, leaving
+the updating flag latched and the Place Order button disabled for the life of the
+page, with every later totals emission discarded as this module's own.
 
 The call carries a `timeout`. Without one a hung request holds `isUpdating()`
 true for the rest of the session, and with it the Place Order button disabled.

Subject: [PATCH 764/885] docs: ABN-561 say what the handover test can and
 cannot separate

The receiving capture re-renders its own chip row before it decides
whether to launch anything, so focus being off the chip afterwards does
not distinguish a launch from that re-render. A handover to a capture
that adopts an autofilled sole trader, or whose popup is blocked,
therefore also suppresses the reclaim.

+That test cannot separate a launch blurring the chip from the receiving capture
+re-rendering its own chip row out from under it, which its chip handler does
+before it decides whether to launch anything. So a handover to a capture that
+adopts an autofilled sole trader, or whose popup is blocked, also suppresses the
+reclaim and leaves the buyer with focus unplaced — the same end state as before
+ABN-561, and the adopt path's own gap, which is out of scope here.
 
 The reclaim decision is read BEFORE returning to registered mode, which can
 remount the panel and so unplace focus the buyer had put somewhere themselves.

 =?UTF-8?q?=20close=20the=20remaining=20silent-refusal=20paths?=

A deselected term's row was still hidden with a bare show/hide, so its
stored cap stayed in the form's validation scope and could refuse the
save from a row nobody can see — the defect ABN-558 exists to remove,
surviving on the one path the first commit missed.

Server-side, only the zero-cap rule was gated on its column being
visible; the fixed and percentage ceilings were applied unconditionally.
The fixed ceiling is derived from an FX-converted merchant setting that
can fall below an amount that was legal when it was entered, so a save
could be refused over a cell the merchant cannot see or edit. Every
ceiling is now skipped while its own column is hidden, which is what the
cap rule already did.

Also: assert the storefront adapter actually routes the picker's phrases
through the harvest dictionary, which was previously undoable with the
whole suite green; restore the wiring assertion alongside the new
harvestability one; make the admin validation-scope test a truth table
over all three columns and mirror the validator's own "has a rule at
all" filter; guard the credit memo's second totals block.

From ad1bd1b6572e43b9295d13c82133edb15dcfc2ed Mon Sep 17 00:00:00 2001

Subject: [PATCH 766/885] fix: ABN-550 confirm the term a partly-applied
 response still committed

Guarding the summary write reverted the chips when a totals subscriber
threw. The endpoint only answers after it has saved, so the server held
the new term while the chips went back to the old one and the summary
kept the new total - reconciled, placeable, and composed on a term the
buyer was not shown. It now confirms the term and logs the partial write.

The guard also only covered the summary write, leaving the confirm and
the revert themselves able to abort jQuery's chain through a throwing
knockout binding and latch the flag the guard exists to protect. Every
write a settled response makes is now guarded.

Adds the status line the chips were missing: the button is disabled while
a call is in flight, so the click-time message cannot be reached, and a
primary button greying out on its own for up to the request timeout reads
as a broken checkout.

 =?UTF-8?q?=20judge=20a=20changed=20value=20even=20on=20a=20hidden=20colum?=

Round 1 skipped a ceiling whenever its column was hidden, which turned an
excused cell into an unvalidated write path: a direct post
(app:config:import, curl) could set a fixed amount over the merchant's cap
on a column no screen shows, and nothing would refuse or rescan it, so a
later store view reading that value would charge buyers above the cap.

The excuse exists for a value the merchant cannot reach — one a
since-lowered, FX-converted cap left stranded. That only applies while the
cell posts back what is already stored, so the ceiling is now skipped only
then. A changed value is an assertion and is judged whether or not it
shows.

Also: mirror every way Magento attaches a validation rule in the admin
validation-scope test, not just this grid's own attribute; resolve the
picker's phrase dictionary once rather than per label render.

Subject: [PATCH 768/885] fix: ABN-550 keep the rollback from pricing one term
 against another

When the repricing back after a failed select-term failed in turn, the
session was still restored while the saved quote kept pricing the staged
term. Placement's cross-check compares those two, so it saw them agree
and composed the order on the previous term carrying the staged term's
fee. The session is now left on the term the quote prices, so the check
refuses the disagreement instead.

Also splits the updating-flag write from the queue flush so a throwing
chip binding cannot strand a queued term, moves the status node out of
its conditional because a live region created together with its text
announces nothing, and pins the exact translated string.

The unchanged-value check read only rows at the exact scope being saved.
The grid renders inherited values, so a merchant taking a first override
at a store or website scope posts the parent's value back with no row of
its own, and every cell read as changed — refusing the save over a cell
the hidden column never shows, which is the dead end ABN-558 is about, one
scope over. The comparison is now against the value in effect at that
scope, which is what the grid rendered.

The percentage ceiling is a code constant that never falls under a
merchant, so no stored value can be stranded above it and hiding the
column earns no excuse: it is enforced unconditionally. The fixed and cap
ceilings keep the excuse, where a lowered FX-converted merchant cap and a
legacy zero respectively make it real.

Also: pin the frontend sales layout file set rather than only its
known-bad member, and describe the admin validation mirror as what it is.

Note on scope: this path is the admin config POST. A `config.php` import
or a direct database write does not reach this model at all and is not
validated here.

Subject: [PATCH 770/885] fix: resolve surcharge table names through
 ResourceConnection

Only ResourceConnection applies the installation's table prefix; the
adapter's own getTableName() just shortens an over-long name. The
surcharge queries asked the adapter, so on a prefixed install they
addressed a table that does not exist and every payment-section save that
reached one of them failed.

Subject: [PATCH 771/885] fix: ABN-561 judge the reclaim on an open signup, not
 on where focus sits

The close watcher could not tell a handover that launched another capture's
signup from one whose receiving capture re-rendered its chip row and launched
nothing: both leave focus unplaced. It now asks every live flow whether a
signup is still open, which is the receiving capture's own answer, and a chip
row that deletes the focused chip while rebuilding hands focus to the company
field.

+**A signup open anywhere on the checkout owns focus, and that is what the close
+watcher asks.** Handing the popup over to another capture launches that
+capture's signup, and that launch blurs its own chip — so focus at the close is
+unplaced either way and says nothing about who owns it. The watcher instead
+polls every live flow for an open popup: one still up is the buyer's place to
+be, and the abandoning capture leaves it alone. A handover to a capture that
+adopts an autofilled sole trader raises no popup, so the reclaim stands.
+
+Read at the close, never latched at the handover: a receiving signup the buyer
+has since closed owns nothing.
+
+**A chip-row rebuild hands focus to the company field.** The row is rebuilt from
+scratch, so activating a chip deletes the node the activation arrived on and
+focus falls to the body — including on the adopt path, where the receiving
+capture re-renders and opens nothing. Only a focused chip the rebuild actually
+disconnected is repaired, so focus the buyer put elsewhere is left alone.
 
 The reclaim decision is read BEFORE returning to registered mode, which can
 remount the panel and so unplace focus the buyer had put somewhere themselves.

Subject: [PATCH 772/885] fix: ABN-550 reprice the rollback on the term it
 restores
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The rollback after a failed select-term repriced the quote while the staged
term was still in the session, and the surcharge collector prices on exactly
that term — so the repricing saved the staged term's fee again and only then
moved the session back. The order was then composed on the restored term
carrying the staged term's fee, which is the divergence the rollback exists to
undo. The session is restored before the repricing, and put back on the staged
term if the repricing fails, so it always holds the term the last persisted
save priced.

The test double now records the session term each repricing saw, which is what
made the ordering invisible to it.

Subject: [PATCH 773/885] test: ABN-550 settle select-term in the shape the
 wire carries

The endpoint answers with its payload inside an array so the webapi serializer
keeps the keys, and the model unwraps that; every case settled a bare object
instead, so the unwrap was never exercised.

Subject: [PATCH 774/885] test: ABN-561 hold the launch blur against the focus
 the rebuild restores

Activating the chip by keyboard now ends with focus on the company field until
the launch blurs it, so the blur is what keeps the signup free of a control a
window return would re-focus. Nothing covered that ordering.

`hasScopeOverride()` still asked the adapter for the config table, so the
prefix fix reached two of the three surcharge queries. This one is on the
render path: a prefixed install failed when drawing the payment-terms
section at a website or store scope, before a save was possible. A
repo-wide test now pins the whole class of bug rather than the three known
sites.

The store-scope test added in the previous commit could not fail on the
code it was written against: the stubbed connection ignores its query, and
it was fed the same rows as the scope config, so a cell with no override
of its own still looked present. The two seeds are now separate, and the
test fails when the value in effect is read from scope-local rows alone.

Also drops a validateValue() default no caller uses, and corrects two
comments that named configuration-import routes which do not reach this
model.

Subject: [PATCH 778/885] fix: ABN-565 keep the capture mode a chip asked for
 across the popup close

The signup popup's close is noticed by a poll running 300ms behind it, and the
poll returned the checkout to registered search whatever had happened since.
A chip the buyer activated while the signup was up therefore had its mode
overwritten: clicking Enter manually left the company field a registered-search
combobox with the registered chip pressed, on every renderer and on both the
autofilled and the no-autofill route into the signup. The close is now only read
as abandonment while the checkout is still in sole-trader mode.

Subject: [PATCH 779/885] test: correct two docblocks naming a parameter
 default that is gone
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Both described the zero rule as held up by a defaulted sixth argument.
That default was removed, so dropping the argument now raises
ArgumentCountError rather than silently passing, and the parameter is
named $columnVisible. The still-true half — that dropping the
`&& $columnVisible` term leaves the suite green while reintroducing the
failed-section-save regression — is what the helper exists for and is all
that is claimed now.

The helper's docblock claimed that dropping the `&& $columnVisible` term
from a rule leaves every other test in the file green. It does not:
dropping it from the zero rule also reds the private-method test for that
rule. What the helper uniquely pins is the call site — replacing the
per-cell visibility expression with a constant reds exactly the three
tests built on this helper and nothing else, which is what it now says.

The parameter list documented a `$scopeLocalRows` argument belonging to
the scope-aware variant while leaving the real fourth argument
undocumented. Each docblock now describes its own signature.

Subject: [PATCH 781/885] ABN-560: base the credit-memo surcharge tax delta on
 what is still refundable

A credit memo raised after an earlier one refunded part of the surcharge
understated its tax by the VAT that earlier memo took. Magento offers a
credit memo the order's invoiced tax less the tax already refunded, so the
surcharge VAT available to this collector is the VAT on the surcharge that
is left; the baseline it compared against was drawn from the whole order
surcharge, and the difference came off the memo's tax total and grand
total. The merchandise row tax, which Magento sets, stayed correct, so the
memo disagreed with itself and a third-party charge added to it was refused
for a tax shortfall.

Subject: [PATCH 782/885] docs: record the lack of table-prefix support as a
 standing gap

Names the two same-named table-name resolution methods and which of them
applies the configured prefix, so the audit that closes this gap does not
start by rediscovering it.

Subject: [PATCH 783/885] Revert the table-prefix fix, leaving the module
 prefix-neutral

The module's direct config-table queries resolve their names through the
database adapter, which applies no table prefix. That is left as it stands
(ABN-558): paths no merchant exercises are not the place for change right
now. The three query sites are byte-identical to the base branch again, and
nothing on this branch adds a fourth.

The repo-wide guard and its unit test go with the fix they pinned. The
standing note in the plugin guide stays and now describes the gap as it
actually is, with the two same-named resolution methods still named so the
audit that eventually closes it does not start from scratch.

Subject: [PATCH 784/885] fix: explain a declined order intent to the buyer
 (ABN-563)

A declined order intent disables the Place Order button. The sentence
explaining that is a brand-configurable notice, and both shipped overlays
withhold it, so a buyer who selected a company the API declines faced a
dead button and an empty tile with no reason given anywhere.

The decline sentence now falls back to platform wording whenever the
brand's own is withheld, the rule the order-intent error notice already
followed: a brand declining to word a verdict has not asked for a blocked
control to be unexplained. The brand switch still chooses the wording.

The sentence also lands inside a live region that is rendered ahead of it,
since an alert element created together with its own text is announced
inconsistently, and the Place Order button points aria-describedby at that
region while the decline stands.

The button stays disabled throughout. Nothing about the verdict, the gate
or the approved notice changes.

Subject: [PATCH 791/885] fix: expose payment control names and selection state
 (ABN-554)

The payment tile's controls did not say what they were or which payment
term was chosen, so assistive technology could not read the tile.

The term chips become a radio group: the container declares
role="radiogroup" and takes its name from the chips' own label, each chip
declares role="radio" and exposes the selection as aria-checked, the group
is a single tab stop, and the arrow keys move the checked term and the
focus together with Home, End and wrapping at both ends. The visual tick
and the exposed state now read one predicate, so they cannot diverge. The
focused chip is identifiable, which a suppressed outline had prevented.

The method radio takes its accessible name from the tile title through a
label, and the consent checkbox from the consent sentence through
aria-labelledby; each association is keyed on the payment code so sibling
brand tiles cannot point at each other's text.

+## The term chips are a radio group
+
+The chips are `button` elements carrying `role="radio"` inside a `radiogroup`,
+and they implement that role's whole keyboard contract: the group is a single
+tab stop — one chip at a time carries `tabindex="0"` — and the arrow keys move
+the checked term and the focus together, Home and End jump to the ends, and both
+ends wrap (ABN-554). Both halves or neither: roles without the keyboard
+behaviour advertise something the group does not do, which is its own defect.
+
+`onTermKeydown` returns true on every key it does not act on, because knockout's
+`event` binding suppresses the default action unless a handler says otherwise —
+without it the group swallows Tab.
+
+`isTermChecked()` is the single definition of a selected chip, read by the
+`aria-checked` binding and by the visual `--selected` class, so the tick and the
+exposed state cannot drift apart. A selection matching no chip — a term the
+merchant withdrew, or one reverted mid-flight — leaves nothing checked, and
+`focusableTerm()` puts the tab stop on the first chip so the group cannot drop
+out of the tab order.
+
+The focus ring is `:focus-visible`, not `:focus`: the group's single tab stop
+makes the focused chip the only thing saying where the keyboard is, while a ring
+on a clicked chip is what the suppressed outline it replaces was avoiding.
+
+**Every ARIA association in the payment template is keyed on the payment code.**
+The chip group's label, the consent checkbox and the consent sentence each take
+their id from `getCode()`, as the declined-notice region does, or a second brand
+tile's controls point at the first tile's text.
+
+The method radio is named by a `label` carrying `for`, so the tile title is both
+its accessible name and a click target for it; the subtitle and the about link
+stay outside that label. The consent checkbox is named by `aria-labelledby` at
+the consent sentence instead, because that sentence carries the terms link and a

Subject: [PATCH 792/885] fix: keep the tile title's inherited colour now it is
 a label (ABN-554)

The rule protecting the title from theme text colours was scoped to span
elements, which the title no longer is.

Subject: [PATCH 793/885] fix: keep the chip nodes and the browser's own arrow
 keys (ABN-554)

Two defects found reviewing the radio-group work, both in the keyboard
contract it exists to provide.

The chips' view models were rebuilt on every fee change, because
`termOptions` was a computed over the per-term fee maps and knockout's
`foreach` replaces every node when its array is recomputed. A
/select-term response rewrites those maps, so the chip the arrow keys had
just focused was deleted a round trip later and focus fell to the body.
The chips are now a plain array built once, each fee an observable of its
own, so the nodes outlive a refresh while the labels still follow it.

A modified arrow key is left to the browser, so Alt+Left still goes back
instead of silently changing the payment term.

Comments and documentation state the current rule rather than the rule
they replaced.

Subject: [PATCH 794/885] fix: say why an unapplied payment term refuses
 placement (ABN-550)

The Place Order button is disabled while the chips' selection is not the
term the server confirmed it priced the quote on, but the chips' status
region only spoke while a call was in flight. A selection that outlives
the call that would have confirmed or reverted it therefore left the
buyer a dead primary button and an empty tile.

The gate and the status text are now one string: the model names the
reason placement is refused, and the gate is that string being empty, so
the two cannot drift apart. The click-time belt shows the same string.

Subject: [PATCH 796/885] test: pin the chip fee call form and the chip array's
 assignment (ABN-554)

Reverting either the template's computed calls or the plain-array
assignment left the whole suite green: a containerless `if` over a bare
computed reads as permanently true, so every chip fee label would vanish,
and a computed at the assignment would restore the chip teardown the
previous commit removed. Both are now pinned, and the chip-identity spec
asserts the labels it actually resolves rather than a deep comparison that
could not fail.

Also repairs a docblock left describing the wrong method and makes the
loading indicator read its computed the same way the fee label does.

Subject: [PATCH 797/885] docs: correct why the chip fee bindings call their
 computeds (ABN-554)

A binding handed a bare computed unwraps it; what fails is negating one
inside an expression, which is the fee label's case. The previous wording
generalised that to every containerless `if`, which the same template
disproves.

Subject: [PATCH 798/885] fix: tell the buyer when a payment term was not
 applied (ABN-550)

A /select-term the server did not take reverts the chips to the confirmed
term and raises a message saying so. The write and the message were in the
opposite order, and a knockout observable assigns its new value before
notifying its subscribers, so a chip binding throwing on that notification
aborted the revert after the selection had already snapped back but before
the message was raised. The chips reverted with no explanation and Place
Order stayed live above a choice the buyer saw silently undone.

Raising the message first makes it independent of the write. The message
text does not depend on any state the write establishes, so no other
rearrangement is needed.

Subject: [PATCH 800/885] fix: measure the surcharge VAT a credit memo was
 granted (follows ABN-560)

Magento's credit-memo tax collector assigns the order's whole remaining tax
allowance on the last memo but bounds any earlier one by the tax its item and
shipping rows carry, so a partial memo is granted no surcharge VAT at all.
Basing the tax delta on the proportional surcharge net assumed the grant in
both cases: a partial memo lost the whole VAT on the surcharge it refunded
from its tax total and grand total, and was then short against its own lines,
which is what refused a third-party charge added to it. Reading the memo's
unitemized tax, the way the sibling other-charges collector reads its own
grant, covers both branches, and capping it at the VAT the still-refundable
surcharge carries keeps the last memo from claiming another charge's share.

Subject: [PATCH 801/885] test: assert each memo in a refund sequence carries
 its own surcharge VAT

Walks a sequence of credit memos against the tax pre-state Magento's own
collector leaves, advancing the order's refunded columns between them, and
asserts every memo's row tax, tax total and grand total. The aggregate across
a sequence balanced even while the individual memos did not, so only per-memo
assertions catch this.

Subject: [PATCH 803/885] refactor: read the merchant surcharge cap through one
 shared resolver

The admin form's fixed-amount ceiling and the runtime charging path have to
agree exactly, or an amount the form accepted gets reduced when the buyer is
charged. Moving the merchant-record lookup and its currency conversion into
SurchargeCapProvider makes that a shared implementation rather than a
convention, ahead of the runtime path acquiring the same ceiling.

Behaviour is unchanged: the admin backend model still compares against the cap
converted into the scope's base currency, still truncates the cap to whole
units before converting and rounds the converted figure up, and still compares
against an unconverted cap when no exchange rate is available. The resolver now
reports that last case, which the charging path cannot treat the same way.

Follows from ABN-558.

Subject: [PATCH 804/885] fix: bound the buyer surcharge by the merchant cap at
 the charging path

The admin form refuses a fixed surcharge above the merchant's cap, and until
now that form was the only thing enforcing it. A value written by a config
import or straight into the config table reaches the per-term surcharge paths
without passing any backend model, so it was relayed to the pricing API and
charged to the buyer unbounded. The cap is also a merchant-record value that
can be lowered under an amount that was within it when saved, which no
write-time check can ever see.

The ceiling therefore applies where the charged amount is decided. An over-cap
amount is reduced to the cap and logged as an error naming the configured
amount, the cap and the term, so a merchant whose configuration is not the
configuration being charged can find out.

A cap that no exchange rate converts into the order currency cannot bound
anything, and an unconverted ceiling in a weaker currency would admit a fee far
above the real one. That case refuses to price, and isSurchargeResolvable()
reports it alongside the existing unresolvable-rate verdict so the buyer meets
an unofferable payment method rather than a checkout error.

Follows from ABN-558.

Subject: [PATCH 805/885] test: pin the merchant surcharge cap on every
 configuration route

The charged-amount table asserts the figure the pricing request carries and the
figure the buyer is charged, because a test asserting the stored value is
unchanged passes against the defect being closed. Rows cover an in-cap amount,
an amount at the cap, an over-cap amount, an amount valid under a cap since
lowered, no cap at all, and a cap that has to be converted into the order
currency first.

The backend-model test records why the admin form cannot be the guarantee: a
save carrying no posted groups neither refuses nor writes the amount, which is
the shape a config import and a direct config-table write both arrive in.

Follows from ABN-558.

Subject: [PATCH 806/885] docs: record where the merchant surcharge cap is
 enforced

The existing note about a surcharge cap of zero is about the per-term Limit
column and says never to guard it at runtime, which reads as forbidding the
ceiling this documents. The new section names the distinction first, then says
why the admin form cannot be the only enforcement and what the read path
guarantees instead.

Also qualifies the "save refuses it" rule: it holds for a path declared as a
field, and the surcharge grid's per-term cells are not.

Follows from ABN-558.

 Neither follows from the other.
 
+## The merchant's fixed-surcharge cap is enforced where the fee is CHARGED
+
+**Not the cap the section above is about.** That one is the per-term **Limit**
+column: a merchant-configured ceiling on the fee, relayed to the pricing API as
+`cap` and never guarded at runtime. This one is `surcharge_limit_amount` and
+`surcharge_limit_currency` on the merchant record — the largest FIXED surcharge
+the merchant is permitted to configure at all. Neither rule transfers to the
+other.
+
+**The admin form is the early warning, not the guarantee.**
+`Model\Config\Backend\SurchargeGrid::validateValue()` refuses a fixed amount
+above the cap and that refusal stays. It cannot be the only enforcement, for two
+reasons neither of which is fixable at the form:
+
+-   The per-term paths
+    `payment/<code>/surcharge_<days>_{fixed,percentage,limit}` are **not
+    declared in `system.xml`** — that backend model writes them itself, and
+    `surcharge_grid` is the only declared field. They therefore carry no backend
+    model at all, so a `config.php` import or a direct `core_config_data` write
+    applies one with no plugin code running. Magento's importer invokes only
+    `beforeSave()`/`afterSave()` on a declared path's model and never supplies
+    the posted `groups` the grid reads, so even a save that does reach this model
+    validates nothing.
+-   The cap lives on the merchant record and is refreshed by cron, so it can be
+    **lowered under an amount that was within it when saved**. No write happens
+    at that moment, so no write-time check of any kind can ever observe it.
+
+**`SurchargeCalculator::capFixedSurcharge()` is the guarantee.** It bounds the
+converted `surcharge` member in the order currency, immediately before the
+pricing request carries it, so no stored value and no write route reaches a
+buyer above the cap.
+
+**A reduction is always reported.** The admin grid goes on showing the
+configured amount, so reducing the fee silently would be a fresh defect rather
+than a fix: the clamp error-logs the configured amount, the cap, the currency
+and the term. Do not quieten it to a debug line, and do not "fix" any of this by
+removing the cap, the setting or the field.
+
+**A cap no rate converts refuses to price.**
+`SurchargeCapProvider::inCurrency()` reports that case as `exact => false`
+rather than handing back a figure in the wrong currency, and the charging path
+raises instead of guessing — an unconverted ceiling quoted in a weaker currency
+would admit a fee many times the real cap. `isSurchargeResolvable()` reports it
+as well, so the method is withheld ahead of pricing and the buyer meets an
+unofferable method rather than a checkout error. The admin form does compare
+against that unconverted figure, which can only refuse MORE than the real cap
+would; that asymmetry is deliberate, and is why one resolver serves both sides
+with the distinction exposed rather than buried.
+
+Both sides read the cap through `SurchargeCapProvider`, so the arithmetic cannot
+drift: the cap is truncated to whole units, and a converted figure is rounded
+up. An amount the form accepted must never be reduced when the buyer is charged,
+and that only holds while a single implementation answers for both.

A fee of zero cannot exceed a cap, so an unconvertible cap said nothing about
it, yet the first version refused to price it and withheld the payment method
over it. That takes the tile off a checkout configured for a fixed surcharge
whose terms all carry zero.

The charging path now returns a non-positive amount before consulting the cap
at all, and the availability check asks whether any offered term carries a
fixed amount before treating an unconvertible cap as disqualifying. That term
scan runs only once an unconvertible cap makes it matter, so the healthy path
still costs one cached merchant-record read.

Follows from ABN-558.

Subject: [PATCH 810/885] fix(checkout): ABN-554 return focus to the company
 field on every popover close

Only Escape handed focus back, so a pointer press outside the popover, focus
leaving it, a company adopted from the results, manual entry taking the field
over and the capture controller's own close all left the buyer standing on a
control that had just gone.

Focus return is now what closing means. The field's own open-on-focus opener is
held off for that one programmatic focus alone, so any keydown on the field, a
click on it, or focus arriving from anywhere else brings the popover back.

Addresses recommendation R5 of the accessibility QA pass.

a chip reading "30 days" on a shop configured that way tells the buyer the
wrong due date. The term type never reached the chip label.

The visible text is now "30 days" under standard terms and "EOM+30" under end
of month, and only the end-of-month chip carries a title and an accessible
name spelling that out. The name opens with the visible token, which WCAG
2.5.3 requires it to contain; a standard chip gets no name of its own because
one restating "30 days" would risk the same criterion.

+## A chip states its term type, not just a day count
+
+An end-of-month term falls due that many days after the end of the month, so a
+chip reading "30 days" on an end-of-month shop states the wrong due date. The
+visible text is `30 days` under standard terms and `EOM+30` under end of month,
+and only the end-of-month chip carries a `title` and an `aria-label` spelling
+that out: `EOM+30: pay 30 days after the end of the month`. The accessible name
+opens with the visible token because WCAG 2.5.3 requires it to contain the
+visible text, and a standard chip gets no name of its own because one that
+merely restated `30 days` would risk the same criterion.
+
+`isEndOfMonthTerms` reaches the renderer from `ConfigProvider`; the chip text and
+the explanation are built by `termChipText()` and `termChipExplanation()`, which
+the sole-term branch reads too. An empty explanation reaches the `attr` binding
+as `false`, not as `''`, because knockout renders a blank attribute and removes a
+false one.
+
 ## The selected term must be CONFIRMED before submit
 
 The order is composed on the term the chips show as selected, so a selection

Subject: [PATCH 812/885] fix(checkout): ABN-554 leave focus alone when it has
 already settled elsewhere

The deferred close-on-focus-leave path runs after the browser has moved focus to
another control, so returning focus there takes the buyer back past the control
they just tabbed off. Every other close path still hands focus to the company
field.

Subject: [PATCH 814/885] fix(checkout): ABN-554 hand focus to the field after
 an outside press leaves it nowhere

A real browser runs the press's own default action after the panel's mousedown
handler: it focuses whatever the press hit, or clears focus altogether where it
hit nothing focusable. So the focus the handler placed on the company field was
immediately undone, and a press on unfocusable page furniture left focus on the
document body with the popover gone.

The focus return for that path now waits a tick and only takes focus where the
press left it nowhere, so a press on another control still lands the buyer
there.

An aria-label replaces the whole accessible name, so the +€n.nn rendered
inside an end-of-month chip was announced nowhere: a screen-reader buyer
choosing between two terms heard both sentences and neither fee.

+The name also states the surcharge, because an `aria-label` replaces the whole
+accessible name and the `+€n.nn` rendered inside the chip is then announced
+nowhere: `EOM+30: pay 30 days after the end of the month, plus a €7.25
+surcharge`. Each wording is one translated sentence rather than an assembled
+one, so a translator can order the clauses. A term carrying no surcharge, and a
+term whose quote has not landed yet, name no amount at all.

 `isEndOfMonthTerms` reaches the renderer from `ConfigProvider`; the chip text and
 the explanation are built by `termChipText()` and `termChipExplanation()`, which
-the sole-term branch reads too. An empty explanation reaches the `attr` binding
-as `false`, not as `''`, because knockout renders a blank attribute and removes a
-false one.
+the sole-term branch reads too. The explanation is a computed over the same fee
+map the visible amount reads, so the name follows the quote in. An empty
+explanation reaches the `attr` binding as `false`, not as `''`, because knockout

+call the computed rather than passing it unwrapped.

Subject: [PATCH 817/885] fix: render the sole offered term as a disabled

ARIA prohibits naming a role-less element, so the span the sole chip used
to be sent its explanatory name to a tooltip and never to a screen
reader. A natively disabled button is named, and is skipped by Tab.

+## The sole offered term is a disabled button
+
+One offered term is not a choice, but it still has to carry the name that spells
+the term out, and ARIA prohibits naming a role-less element — which a bare
+`span` is. So the sole chip is a `button` with the native `disabled` attribute:
+naming works, and a natively disabled button is not focusable, so the tab order
+skips a chip that has nothing to select. It keeps the `two-term-chip--single`
+class, which is its whole appearance; the base chip rules already set border,
+background, padding and font because the multi-term chips are buttons too.

Subject: [PATCH 818/885] fix(checkout): ABN-554 place focus again after a
 capture-mode change
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

A mode change takes away whatever held focus: the chip row is rebuilt from
scratch, and a mode that withdraws the query row hides the input the caret was
in — which is where a pointer buyer's focus actually is, since the chip's own
press cancels the native focus. The reclaim asks whether that node survived
rather than where focus is, because the browser's blur for a hidden row lands
after the handler that hid it.

Escape was bound to the query field alone, which is withdrawn outside
registered-company mode — so a buyer on a mode chip, with the popover drawn
over the control below the field, had no keyboard route out.

Subject: [PATCH 820/885] fix(checkout): ABN-554 make a press on the popover's
 dead space a no-op

The press's default action blurred the caret out of the query field, leaving
the open popover holding nothing. A press on a control still focuses it, and a
press on a scrollbar still drags, so the results keep scrolling.

Subject: [PATCH 829/885] fix(company-search): park the focus the sole-trader
 signup popup takes

ABN-554. Opening the hosted signup window blurs the control that launched
it, which left the capture popover on screen around a document focusing
nothing: document.activeElement = BODY, and no keystroke reaching any
control. Focus is now parked on the company field, and the return watch
reads that control as its own until focus leaves it.

Subject: [PATCH 830/885] fix(ABN-550): hold placement and tell the buyer in
 the tile when a term is refused

A /select-term the server would not take reverted the chips to the
confirmed term, which restored the selected/confirmed parity both the
tile's live region and the placement gate are derived from: the region
rendered nothing and Place Order stayed enabled on a term that was never
applied. The refusal is now held as state of its own until the buyer
clicks a chip again, and the page-level banner it used to go to is gone.

A park landing after the flight settled would leave focus the abandon

one arrival on.

Focus the plugin parked would otherwise answer the reclaim's 'has the
buyer placed it themselves' predicate, and a mode change that remounts
the panel could then leave focus nowhere with nothing to restore it.

UA outline away a keyboard-focused mode chip was invisible (WCAG 2.4.7).

Subject: [PATCH 837/885] ABN-554: keep the sole offered term chip solid on
 Luma
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The chip is natively disabled so Tab skips it, which puts it in reach of
the theme's own button:disabled fade — the buyer's only term rendered as
an unavailable control. Hyva already renders it solid.

Subject: [PATCH 838/885] fix: admin surcharge grid shows the stored amount
 under differential mode

The default-term row's cells were rewritten to 0 in the DOM while the
server-rendered value still carried the configured amount, so a merchant
could not read back a fee that is charged in full.

Subject: [PATCH 839/885] ABN-554: a fee its own extension refunds must not
 reach Two's residual

Amasty Extra Fee runs its own credit-memo total collector. Two reconciled
that fee as an unclaimed residual and offered it for refund, so a memo could
credit a fee Amasty had already decided was non-refundable, and the same
fee's VAT was then deducted twice from the last memo's tax allowance.

Claims the fee through the existing FeeLineProviderInterface seam, reading
Amasty's own tables, so it never reaches the residual on any entity.

Subject: [PATCH 841/885] ABN-554: lock the vendored company-search panel to a
 shared digest

The two copies of the panel module are now byte-identical, and each repo's
JS suite pins the same sha256, so the two constants are the parity check.
AGENTS.md said a whole-file re-copy was the only way back in step, which
would have overwritten whichever side held the difference.

Subject: [PATCH 845/885] ABN-554: surcharge line label follows the
 end-of-month basis
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The shipped default in etc/config.xml made getConfig() never empty, so the
existing fallback was dead and an end-of-month order's fee line read
"Payment terms fee - 30 days" — understating the term the buyer agreed to.

Subject: [PATCH 846/885] ABN-554: resolve the shipped default per brand, not
 from a constant

Review round 1: the customisation test compared the stored value against a
hardcoded base-module default, but the config path is brand-scoped and each
brand overlay ships its own wording. On any such store an uncustomised
merchant read as customised and the end-of-month label never appeared.

The shipped default now comes from config.xml for the active brand, and the
end-of-month wording from a sibling config.xml key each overlay can ship.

Subject: [PATCH 847/885] ABN-554: proxy and memoise the shipped-default lookup

Review round 2: Initial was injected eagerly into a class built on checkout
hot paths, and its config tree was re-indexed on every call.

Tests now pin the store scope reaching scopeConfig, the scope Initial is
asked for, and the degraded path where no Initial is wired.

Subject: [PATCH 848/885] ABN-554: fall back to the brand's shipped wording,
 not the base module's

Review round 3: a blank stored row resolved to this module's wording, so a
brand overlay shop whose admin cleared the field showed the wrong label.

Every config read the method makes is now pinned to the caller's scope.

A printable key on a focused chip only reached the company field where the
country gate had withdrawn the search; a mode that withdraws it leaves the same
button swallowing the character. The withdrawn search row's message is dropped
on every sync again — only the query value is now held back for the character
the field's opener moves across.

Subject: [PATCH 852/885] ABN-554: keep the buyer's text in the field a mode
 with no query row leaves them

Where the signup popup is blocked the mode never returns to registered company,
and carrying the keystrokes into a withdrawn query row put them somewhere the
buyer could not see while blanking the box they were typing in. The text now
stays in the field and the query holds a copy for the row a mode change reveals.
A panel given no mode reads as registered company, which is the only mode that
has a search at all.

Subject: [PATCH 855/885] fix(ABN-554): repaint the Luma order summary on the
 selected term
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

/select-term's response carries the re-collected totals flattened to
code/title/value, and writing them into Magento's totals observable hands
every summary subscriber a segment stripped of its extension attributes.
Amasty's fee component reads one, throws inside knockout's notification,
and every subscriber after it — the fee row, tax and order total — never
re-renders. The buyer keeps seeing the previous term's figures right up to
placing the order.

The summary is now refetched through Magento's own get-totals action once
/select-term has saved the re-collected quote, so it repaints from the
server in the shape every subscriber expects. A refresh a newer term has
overtaken is dropped before it can write.

Subject: [PATCH 856/885] fix(ABN-554): let a refused summary refresh go

Review round 1: a totals fetch that never answered left the model waiting
for its own write, so the next totals change was taken as that write and
the chip fees stopped refetching until the buyer clicked another chip.

Subject: [PATCH 857/885] ABN-554: keep the selected chip's tick out of its
 accessible name
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The tick is CSS generated content, which Chrome folds into the name —
`✓ 30 days +£0.50` where the chip reads `30 days +£0.50`. `aria-checked`
already states the selection, so the tick is redundant to assistive
technology; an empty alternative text leaves it drawn and unnamed.

Subject: [PATCH 858/885] ABN-554: the company-search panel says what a search
 returned

The panel painted rows into a listbox with no live region anywhere on the
page, so a screen-reader buyer got silence for every search outcome. It now
carries the same live region the reference panel gets from its autocomplete
widget, and the query field's aria-expanded stops claiming an expanded list
while the panel is hidden.

The WooCommerce copy of the panel carries the identical edit and the same
moved digest.

The too-short hint is re-rendered on every keystroke below the threshold, so
announcing from _renderMessage interrupted the buyer with it on each one.

Subject: [PATCH 860/885] ABN-554: the announcement reaches the storefront JS
 dictionary

Magento harvests the dictionary by scanning for literal $t() calls, so a
phrase the panel only asks its host for by name renders in English.

Subject: [PATCH 861/885] fix: hold the field's focus opener across a
 sole-trader signup flight

ABN-554. A browser re-fires focus on the control the opener window still
holds when the signup popup closes, which reopened the company-search
popover behind an adopted trader; and the park exemption was dropped on
the focusout the window blur itself fires, so a buyer clicking back into
the checkout closed their own live enrolment.

Subject: [PATCH 862/885] feat(checkout): one what-is-Two icon with a
 hover/focus tooltip

ABN-554: the text about-link is replaced by a tooltip icon wrapped in the
anchor to the brand's about page, so the control is reachable by keyboard
and carries the explainer copy.

popup the browser blocks armed no watcher to perform it.

Subject: [PATCH 865/885] fix: end the field-opener hold on the window's
 return, not the popup's close
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The opener re-fires `focus` and `focusin` on its focused control when the
window regains focus, which a live browser was measured doing a second to a
minute after the popup went away — so releasing on the close poll left every
buyer away for longer than one poll with the defect. The hold now stands until
that pair arrives beside a window focus, and buyer intent on the field clears
it outright.

Subject: [PATCH 866/885] fix: open the popover on a Tab arrival that lands
 during a signup flight

A held field opener swallowed every focus pair, so a buyer arriving on the
company field by keyboard while the hold stood got no popover at all.

Subject: [PATCH 867/885] fix(checkout): the what-is-Two icon sits beside the
 tile title

The title block is a column, so the about control rendered on its own row
below the subtitle. A row wrapper puts the icon inline with the title, as
WooCommerce and PrestaShop render it.

Escapes the brand name reaching the html-bound tooltip, matching
getSubtitleHtml.

Subject: [PATCH 868/885] fix(a11y): the closed about tooltip leaves the
 accessibility tree

ABN-554. The box is closed by opacity alone, so without aria-hidden a screen
reader announces its prose twice: once as the link's aria-describedby
description, once in document flow. Matches WooCommerce and PrestaShop.

Subject: [PATCH 869/885] ABN-554: sanitise the checkout tile subtitle to text
 plus a single link

The renderers bind the subtitle unescaped, so AnchorOnlyHtmlEscaper is now the
only gate on it: an <a> with an http(s) href survives, rebuilt with only the
target and rel this module emits, and every other tag and attribute is dropped.
The Subtitle admin field's help text now matches the other two plugins.

Subject: [PATCH 870/885] fix(checkout): the about control is flow content, and
 ships nothing when withheld

<span> is phrasing content and the tooltip body holds <p>s, so the wrapper
and the body are both divs, matching WooCommerce. The icon asset URL and the
icon's accessible name now follow the control's visibility, as its other keys
already did.

Subject: [PATCH 871/885] ABN-554: close the round-1 review findings on the
 subtitle escaper

Shared escaper fixes, identical in all three plugins: guard the absent
capture group that made `<a href="">` emit a PHP warning into the checkout
markup; reject a userinfo component in the href; substitute malformed UTF-8
instead of blanking the whole text run; strip control characters; and stop a
stray `<` swallowing the copy up to the next `>`. escape() now coerces its
argument like the other two rather than rejecting a non-string outright.

Fifteen more escaper rows plus an idempotence pass, which between them kill
the six mutants the previous suite let live.

Magento-only: a row covering the widening this PR introduces - a merchant
subtitle carrying its own link, which the previous htmlspecialchars call
flattened to text.

Subject: [PATCH 873/885] ABN-554: state the real reason the closed tooltip
 keeps its box

The rule is opacity so the open transition has a fadeable property, not an
accessibility-tree constraint: an accessible description resolves a directly
referenced node even when it is hidden. Brings this repo in line with the
PrestaShop and WooCommerce wording.

Subject: [PATCH 875/885] fix: escape translated tooltip copy in the checkout
 tile (ABN-554)

getAboutTooltipHtml() concatenated raw (string)__() results into its own
<p>/<strong> wrappers, so an admin-edited translation rendered unescaped
through the renderer's html: binding. Each phrase is now escaped alone,
which leaves the method's own wrappers intact.

Subject: [PATCH 876/885] test: cover escapeTextOnly directly and widen the
 tooltip payload rows

Review round: the new public escaper method had only transitive coverage,
the tooltip rows shared one payload, and two docblocks did not state the
escaping contract they now carry.

Subject: [PATCH 877/885] test: drop the duplicated entity row and the restated

inline comment repeated the docblock, and the wrapper-count assertion
reported the payload's message.

Subject: [PATCH 881/885] ABN-554: rebuild company-row labels as nodes
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The search API's `highlight` is registry-sourced markup rendered straight
into the buyer's checkout. Rows now keep only bare <mark>/<b> elements —
the pair the API emits — and every other shape reaches the DOM as text.
