📝 WalkthroughWalkthroughThe PR updates documentation for the cloud runtime, in-process harnesses, authentication, vendored crates, CLI behavior, routing, and multi-session TUI workflows. It also corrects several documented source paths. ChangesRuntime transition and documentation
Estimated code review effort: 1 (Trivial) | ~5 minutes Merge Risk: 🟡 Moderate · up to The PR substantially updates developer documentation, but the current head still contains contradictory or misleading guidance about authentication persistence, logout state, readiness and offline behavior, runtime transport, configuration precedence, and workspace/provider semantics. The impact is limited to developer and operator understanding rather than product behavior, but these issues should be corrected or explicitly accepted before the documentation rewrite is considered merge-ready.

Link the implementation paths to medulla-src
This newly added implementation reference points at src/sdk/... as though that tree existed in this public repository, so readers cannot follow it; the same pattern was added for hub/plane, the E2E examples, and several paths in docs/vendoring.md. Replace these references with canonical https://github.com/tinyhumansai/medulla-src/tree/main/src/... links as required for source-tree references.

Remove the automatic mock fallback claim
For signed-out or unconfigured launches, this paragraph contradicts both the immediately preceding statement that --mock is the only offline path and the new readiness documentation in troubleshooting.md, where a signed-out backend opens login and a missing backend URL stops with an error. It also claims the login screen offers m, while the new authentication and troubleshooting pages explicitly say it does not. Document the three readiness outcomes consistently so users do not expect an implicit offline session.

Keep the account marker after logout
When a user logs out, this says active_user.toml is cleared, but the newly rewritten authentication page explicitly says logout deliberately leaves the marker in place so the same account home and deployment configuration remain selected. Readers relying on this glossary entry will therefore expect the next command to resolve the local home when it actually continues using the logged-out account's home.

Inline comments:
In `@docs/TERMINOLOGY.md`:
- Around line 49-50: Update the opening definition of “harness” in the
terminology documentation to include selected providers or runtimes, not only
coding-assistant CLIs, so it accurately covers the OpenHuman and Shell entries.
In `@gitbooks/developers/architecture.md`:
- Around line 46-48: Update the response-envelope statement in the architecture
documentation to apply only to non-streaming JSON routes, and add a separate
clarification that SSE streams use event framing rather than the JSON envelope.
Preserve the existing typed error and transport descriptions.
In `@gitbooks/developers/authentication.md`:
- Around line 213-224: Update the token-handling documentation near the TUI
`/auth/me` flow to state that storing the token and continuing without a restart
applies only when it belongs to the current account; preserve the separate
behavior for tokens belonging to a different account.
- Around line 142-144: Verify the logout store behavior for the active_user.toml
marker, then update the conflicting documentation so authentication.md,
configuration.md, and glossary.md consistently describe whether logout preserves
or clears it; ensure the documented contract matches account home resolution
after logout.
In `@gitbooks/developers/cli-reference.md`:
- Around line 90-92: Revise the documented explanation around the `medulla run
--config` behavior so it does not claim the resolved config always comes from
the Medulla home. Clarify that explicit `--config` bypasses discovery and only
the login session and other home-scoped state follow `MEDULLA_HOME`, while
preserving the existing description for runs without `--config`.
In `@gitbooks/developers/configuration.md`:
- Line 253: Update the provider environment-variable documentation at
gitbooks/developers/configuration.md:253-253 and
gitbooks/developers/environment-variables.md:48-59 to exclude the in-process
OPENHUMAN provider from <P>_BIN, <P>_ARGS, and session-polling variables. Keep
MEDULLA_OPENHUMAN_BIN documented only for standalone wrappers and PTY sessions,
while retaining the existing custom-harness documentation for the in-process
route.
- Around line 136-138: Update the readiness guidance in
gitbooks/developers/configuration.md lines 136-138,
gitbooks/developers/troubleshooting.md lines 104-115, and
gitbooks/features/routing.md lines 101-105 to match Readiness: configured
backends without a usable token are SignedOut and must open the login flow;
missing effective backend URLs are Unusable, must report the error, and must
stop. Reserve the offline runtime exclusively for explicit --mock and remove any
conflicting credential-free fallback guidance in all three locations.
In `@gitbooks/developers/contributing.md`:
- Around line 29-31: Update the cargo run documentation around CloudRuntime’s
no-session behavior to state that it opens the login screen and requires
pressing m to continue in offline mock mode, rather than implying an immediate
automatic fallback.
In `@gitbooks/developers/getting-started.md`:
- Around line 99-101: Update the Platform support paragraph so the
backend-over-HTTP statement applies only to the interactive TUI and medulla run;
describe medulla update separately as contacting the release manifest for
self-update behavior.
In `@gitbooks/developers/glossary.md`:
- Around line 212-218: Update the glossary entry describing the TUI-driving
trait to qualify snapshot and subscribe as the two state-observation methods,
rather than claiming every surface depends only on them. Preserve the existing
description of RuntimeSnapshot and event folding, and acknowledge the broader
runtime contract only as needed to avoid excluding describe, submit,
submit_with_receipt, and abort.
In `@gitbooks/developers/README.md`:
- Line 11: Update the workspace description in the introduction so its stated
crate count matches the crates listed; include the missing third crate, using
the existing repository links and crate names, or correct the count if only two
crates belong to the workspace.
In `@gitbooks/developers/the-tui.md`:
- Around line 184-190: Update Medulla’s Claude Code hook-log handling so a
Notification is treated as a wait only when its event name denotes an
attention-required event; exclude auth_success and completion notifications
while preserving the existing screen-specific precedence and Claude-only
fallback behavior.
In `@gitbooks/developers/vendoring.md`:
- Around line 60-62: Update the feature description to state explicitly that
both the sqlite and tools features are disabled by default, and replace
“builtin” with “built-in” when describing the tool family.
In `@gitbooks/features/workers-and-sessions.md`:
- Around line 227-229: Update the live-feed transport description in the
sessions documentation to match the architecture documentation, selecting one
authoritative mechanism instead of describing both polling and SSE. Explicitly
document the reconnect behavior, including how the client resumes from the event
cursor without losing replayable session history.
- Around line 51-54: Update the local fleet path documentation to clarify that
it is declaration-only: it renders declared capacity, including with --mock, but
does not provide live worker management or task steering. Remove or revise any
wording that describes it as a local orchestrator or management fallback.

Define harness to include non-CLI providers.
The opening definition still says harness identifies the coding-assistant CLI that runs a session. These rows add OpenHuman and Shell, which are not coding-assistant CLIs. Define harness as the selected provider or runtime, or state that the table also contains non-CLI values.

Scope the envelope statement to JSON API responses.
The page lists SSE as a backend client surface, then says every response uses { "success": ..., "data": ... }. An SSE stream uses event framing rather than this ordinary JSON envelope. Restrict the claim to non-streaming JSON routes and document SSE separately.

Name the third workspace crate or correct the count.
This sentence calls medulla-src a three-crate Cargo workspace but names only medulla and medulla-tui. The PR objectives identify tinyagents, tinyflows, and tinyhumans-sdk as the three self-contained crates.
Update the sentence and links to list all three crates, or change the count if the third crate is not part of this workspace. The current wording leaves the developer workspace map incomplete.

The following events fall under the Notification hook category [3][4][5]: - permission_prompt: Fires when Claude needs approval for a tool use or a sandboxed command's network request, and the prompt has waited approximately six seconds [3][1]. - idle_prompt: Fires when Claude has finished responding and remains idle for approximately 60 seconds [3][5]. - auth_success: Fires when authentication completes [3][2]. - elicitation_dialog: Fires when an MCP server opens an elicitation form and the user has not typed for approximately six seconds [3][5]. - elicitation_url_dialog: Fires when an MCP server requests that the user open a browser URL and the user has not typed for approximately six seconds [3]. - elicitation_complete: Fires when an MCP elicitation form is submitted or dismissed [3][1]. - elicitation_response: Fires when an MCP elicitation response is sent back to the server [3][1]. - agent_needs_input: Fires when a background session begins waiting for user input (only while agent view is open) [5]. - agent_completed: Fires when a background session finishes or fails (only while agent view is open) [3][5]. - quota_auto_resume_fired, quota_auto_resume_stale, and quota_auto_resume_disabled: Various events related to quota auto-resumption status [3]. Important usage notes: - Each notification includes a message field containing a human-readable description and optionally a title [1][2]. - While Claude Code emits these notifications, some interactive UI-specific notifications (like idle_prompt, auth_success, and elicitation_dialog) may not be triggered in non-interactive Agent SDK sessions, which instead focus on events like permission_prompt [1]. - You can implement these hooks using various methods, including shell commands, HTTP endpoints, or MCP tools [6][7].

Filter Notification events by event name.
When Medulla uses the Claude Code hook log, treat only attention events as waits. Claude Code also emits auth_success and completion notifications. Otherwise, a successful login can create a false ⚠ mark.

Correct the feature description wording.
The sentence Neither tinyagents feature is on by default in the crate uses singular wording for two features. State explicitly that the sqlite and tools features are disabled by default. Also spell builtin as built-in.

Define the local fleet path as declaration-only.
The local path is documented as a fallback for rendering declared capacity, including on --mock; it does not provide live worker management or task steering. State this distinction here, or remove the local-orchestrator wording.

Use one live-feed transport description.
gitbooks/developers/architecture.md says both that cloud polls an event cursor and that the backend client uses SSE. Align these statements and document how reconnects work.

The docs, gitbooks and installers were split out of
medulla-srcon 24 Aug and have not been updated since — which is exactly when the embedded OpenHuman core was removed. Nearly every developer page still described an architecture that no longer exists: an embedded core owning the runtime, the credential store, the workflow wire types and the vendored dependency graph.26 files. Every claim was re-derived from
medulla-srcat v0.11.1.scripts/check-public-boundary.shpasses; all relative links and heading anchors resolve.Pages that were wrong, not merely stale
developers/vendoring.mdanddocs/vendoring.md— full rewrites. Both documented avendor/openhumansubmodule carrying sixteen nested submodules (including a Tauri fork bundling CEF) and a ten-entry patch table that had to be kept in lockstep by hand. Reality is three self-contained crates —tinyagents,tinyflows,tinyhumans-sdk— and a two-entry patch table. The old page also gavetinyflowsas0.5at a commit that is no longer the pin, claimedtinyagentsarrives transitively throughtinycortexwhen it is now a direct submodule, and never mentionedtinyhumans-sdkat all.developers/authentication.md— rewritten. The page said the session lives in the embedded core's credential store, "the OS keychain where one is available". There is no keychain code anywhere inauth/. The session is a0600session.jsonunder the per-account home, written to a temp file and renamed, with theactive_user.tomlmarker published only after it lands. Now documents the real precedence chain (backend.token→backend.tokenEnv→ stored session), issuer-scoped sessions, the login/logout refusals and their exact messages, and account-id sanitization.It also had the legacy-credentials behaviour backwards:
loginadopts a retiredcredentials.json(verifies its JWT, rewrites it as a session, removes the old file only afterwards) and onlylogoutdeletes one — because leaving one at logout would sign the operator straight back in on next launch.developers/architecture.md,sdk.md,configuration.md,cli-reference.md,the-tui.md,troubleshooting.md,glossary.md,harness-integration.md,features/routing.md,getting-started.md,contributing.md—cloud/mockruntimes in place of the core, the in-processopenhumanprovider ontinyagents, thehub/planewire contract, and three crates rather than two.sdk.mdwas documentingOpenHumanRuntime::new(core), a type that no longer exists, and claimed the HTTP/SSE runtime had been removed when it is in fact the current one.Also corrected:

It is a rail plus one live pane, and the docs say so.
Left for a human
README.mdandpricing-and-availability.mdboth say access is rolling out to "a small group of OpenHuman subscribers first".
