… (peat#904 Phase 2 — part 1)
Implements ADR-066's four-tier vocabulary across the hierarchical
aggregation core:
Squad → Cell, Platoon → Cohort, Company → Federation,
+ new Coalition top tier.
src/hierarchy/deltas.rs:
- SquadDelta/SquadFieldUpdate → CellDelta/CellFieldUpdate

- peat-protocol/src/hierarchy/platoon.rs (1-byte empty stub)
cargo +stable test --workspace passes.
…t#904 Phase 2 — part 2)
Carries the ADR-066 four-tier vocabulary into the security, error,
event-routing, and cell-formation surfaces.
src/security/authorization.rs:
- HierarchyLevel: Node/Squad/Platoon/Company/Battalion
→ Node/Cell/Cohort/Federation/Coalition (top tier per ADR-066)
- Derived `PartialOrd`/`Ord`/`Default` so comparison code outside
peat-protocol (e.g. the TAK bridge tier filter) can rely on
`Node < Cell < Cohort < Federation < Coalition`
- Permission::FormPlatoon → FormCohort
- Permission::AggregateToCompany → AggregateToFederation
+ NEW Permission::AggregateToCoalition for the top-tier op
- Display + default policy + tests updated
src/security/{user_auth,audit}.rs: doc/example string refresh.
src/error.rs:

- ErrorContext.squad_id → cell_id (+ tests)
src/event/aggregator.rs:
- EchelonType removed; replaced by re-export of HierarchyLevel
- EchelonAggregator → HierarchyAggregator (with `tier`/`tier_id` accessors)
- All test fixtures use Cell/Cohort/Federation/Coalition vocabulary
src/event/{mod,query,emitter,priority_queue,summary,transmitter}.rs:
- Public re-export surface aligned with HierarchyAggregator
- Doc-comments and test fixtures use the new tier vocabulary
src/cell/{coordinator,capability_aggregation,election_policy,
leader_election,messaging}.rs:
- squad_id → cell_id, "squad leader" prose → "cell leader"
- FormationStatus + CellCoordinator surface preserved (cell already
the canonical inner module)
src/models/{cell/mod.rs,cell/tests.rs,role.rs,operator.rs,mod.rs}:
- CellState.platoon_id → cohort_id (peat-schema Phase 1 wiring)
- assign_platoon/leave_platoon → assign_cohort/leave_cohort
- Test variable names (`squad` → `cell`) and fixture strings normalized
- Legacy `Squad*` aliases dropped from models/mod.rs; Platform* kept
Removed:
- peat-protocol/src/squad.rs (dead stub, was not in lib.rs)
cargo +stable test --workspace passes.
…904 Phase 2 — part 3)
Sweeps the remaining peat-protocol modules to the ADR-066 vocabulary.
src/command/{routing,coordinator,mod,policy_impl,conflict_resolver,
storage_trait}.rs:
- CommandRouter: squad_id/squad_members → cell_id/cell_members
- Scope::Squad/Platoon match arms → Cell/Cohort + new Federation/
Coalition arms (defer to higher-tier coordinator for routing)
- TargetResolution::AllSquadMembers → AllCellMembers
- derive_authority_level prefix heuristics: cohort-*/cell-* (was
platoon-*/squad-*) — non-wire vocabulary, doc-only
- All command tests/fixtures use cell-/cohort- IDs
src/discovery/{geographic,coordinator,directed,capability_query}.rs:
- MIN_SQUAD_SIZE → MIN_CELL_SIZE
- can_form_squad / find_formable_squads / should_initiate_squad_formation /
get_squad_members → can_form_cell / find_formable_cells / etc.
- ValidationResult::SquadNotFound/SquadFull → CellNotFound/CellFull
- transition_to_squad_phase → transition_to_cell_phase
- avg_squad_size → avg_cell_size, squads_formed → cells_formed
src/composition/rules.rs:
- doc-comment "Cell or squad ID" → "Cell ID"
src/mesh_integration/aggregator.rs:
- PacketAggregator now wraps StateAggregator::aggregate_cell
- extract_squad_summary → extract_cell_summary
- SquadSummary payload type → CellSummary
src/network/peer_config.rs:
- doc/example formation id "alpha-company" → "alpha-federation"
src/sync/automerge.rs:
- DQL test fixtures + query strings refreshed to cell/cohort vocabulary
- Internal comment: "soldier"/"squad leader" → "member"/"cell leader"
examples/secure_node.rs:
- AuthorizationContext::for_cell("alpha-squad") → "alpha-cell"

…ase 2 — part 4) tests/event_routing_integration.rs: - EchelonAggregator/EchelonType → HierarchyAggregator/HierarchyLevel - Test fixture IDs use cell-/cohort-/federation- vocabulary - New `test_tier_hierarchy` covers Cell < Cohort < Federation ordering tests/discovery_e2e.rs, tests/mdns_discovery_e2e.rs: - MIN_SQUAD_SIZE → MIN_CELL_SIZE, get_squad_members → get_cell_members - "alpha-company" formation id → "alpha-federation" tests/hierarchical_sync_e2e.rs: - Topology header re-labelled Cohort/member (was Platoon/soldier) tests/hierarchical_sim_test.rs: - Role/fixture strings normalized to coalition/cohort/cell/member tests/iroh_file_distribution_e2e.rs: - "alpha-squad" distribution scope → "alpha-cell" peat-schema/src/ontology.rs: - Phase 1 missed the `test_ontology_creation` test still asserting the old "platoon" concept key; corrected to cell/cohort/federation/coalition (matches the concepts already registered by build_cap_ontology). - Updated "hierarchy" concept description from "(platoon/company)" to "(cohort/federation/coalition)". cargo +stable test --workspace now passes end-to-end.
…eat#904 Phase 2 — part 5) src/tak/bridge/config.rs: - EchelonLevel enum removed; the bridge now re-exports peat_protocol::security::HierarchyLevel. - Old EchelonLevel had a structural bug where Squad and Cell were adjacent distinct levels (pre-rename); collapsed to Cell. Formation semantically corresponds to Coalition. - AggregationPolicy::SquadLeaderOnly → CellLeaderOnly - should_publish_echelon → should_publish_tier, viewer_echelon → viewer_tier; filtering logic rewritten over the four tiers. - Tests cover Node < Cell < Cohort < Federation < Coalition ordering (derived from HierarchyLevel's PartialOrd/Ord). src/tak/bridge/mod.rs: - PeatMessage::echelon() → tier(), returning HierarchyLevel - FormationSummary now maps to HierarchyLevel::Coalition (top tier) src/tak/bridge/filter.rs: - should_publish_echelon → should_publish_tier in BridgeFilter - Test renamed test_bridge_filter_echelon → test_bridge_filter_tier - "filtering friendly platform" → "filtering friendly node" src/lib.rs: - Pre-existing broken doctest (AutomergeIrohBackend::new() needs args) marked `rust,ignore`; it was previously hidden by other compile errors in the workspace and surfaced cleanly after the rename. The bridge still reads external CoT type strings verbatim (e.g. "a-f-G-U-C-I") — those are wire-format artifacts and remain untouched, only peat-side identifiers were renamed. cargo +stable test --workspace passes.

Peat QA Review (SHA: 5a26cee)
Scope: peat-schema, peat-protocol, peat-transport vocabulary rename (Squad/Platoon/Company/Battalion → Cell/Cohort/Federation/Coalition) plus net-new Coalition tier. No cryptographic primitive changes. No peat-mesh (Iroh/Automerge sync wire protocol) changes — Phase 3 per PR description. FFI/BLE surface not touched; no UniFFI/JNI/BlueZ review required.
[WARNING] security.proto HierarchyLevel value 4 reused with new semantics
HIERARCHY_LEVEL_BATTALION = 4 → HIERARCHY_LEVEL_COALITION = 4. Values 5 (BRIGADE) and 6 (DIVISION) are removed from the enum entirely. Any persisted binary-protobuf DeviceIdentity records carrying BATTALION will silently decode as COALITION on upgrade; records carrying BRIGADE or DIVISION will silently decode as HIERARCHY_LEVEL_UNSPECIFIED (0) — proto3 treats out-of-range enum values as the zero default.
ADR-066's no-alias policy drives the intentional value reuse, but there is no annotation in the proto file or upgrade note calling out the silent semantic mutation at value 4 and the silent drop at 5–6.
Action: Add a comment in security.proto at the HierarchyLevel enum (or in the ADR-066 reference doc) explicitly documenting the wire-semantic break at value 4 and that values 5–6 now decode as UNSPECIFIED. If any deployed nodes carry these values in stored identity records, document the required re-provisioning step before merge of any release built on this branch.
[WARNING] Automerge storage key prefixes renamed with no migration path
AutomergeSummaryStorage key format changed across all tiers: squad-summary:* → cell-summary:*, platoon-summary:* → cohort-summary:*, company-summary:* → federation-summary:*. Any Automerge store with existing documents under the old key prefixes will silently return None after upgrade — existing summaries are orphaned in place with no error.
The PR correctly notes that no release is unblocked without Phase 3 integration tests. But Phase 3 will exercise AutomergeSummaryStorage against nodes that may carry state from pre-rename test runs, and get_cell_summary returning None for a pre-existing squad-summary: document is a silent data-loss path.
Action: Either add a one-time key migration step in AutomergeSummaryStorage::new() (scan for old-prefix keys, re-write under new prefixes, delete originals) or explicitly document in Phase 3 test setup that stores must be provisioned clean. The pub(crate) cell_key / cohort_key / federation_key / coalition_key helpers introduced here are a good hook point for such a migration.
[WARNING] Scope::Federation | Scope::Coalition routing paths have no test coverage
command/routing.rs introduces a new match arm for the two new tier scopes. All routing tests in the diff exercise Scope::Cell, Scope::Cohort, Scope::Individual, and Scope::Broadcast; none exercise Scope::Federation or Scope::Coalition. The fallback behavior (cell-leader fanout vs. self-target) is non-trivial and was explicitly flagged in the PR description under "Semantic decisions worth reviewer attention."
Action: Add unit tests for Scope::Federation and Scope::Coalition covering at minimum: (a) node is cell leader → AllCellMembers; (b) node is not cell leader → Self_. These should live alongside test_resolve_cell and test_resolve_individual_self in the existing mod tests block.
[ARCH] Scope::Federation | Scope::Coalition command routing implicit fanout design
The new match arm in CommandRouter::resolve_target falls back to AllCellMembers(cell_members) for any node that leads a cell, independent of whether that cell is actually part of the targeted federation or coalition. A Scope::Federation command addressed to fed-1 will fan out to all cell members on any cell-leading node that sees the command — including nodes in entirely different federations. The router has no federation/coalition membership signal to gate this.
The PR description raises this explicitly and suggests it mirrors Scope::Broadcast behavior, with higher-tier coordinators selecting targets at the coordinator layer. That may be the right call, but the consequence is that federation-scoped commands become de-facto broadcasts at cell boundaries, which could be surprising at Coalition scale (~1000+ peers) if not explicitly intended.
Action: Escalate for explicit design decision: should CommandRouter drop Federation/Coalition commands when it has no membership signal for those tiers (stricter "not for me → NotApplicable"), or is implicit cell-level fanout the intended behavior? Do not inline-fix — this is an ADR-territory question about command delivery semantics at tier 3/4.
[IDIOM] peat-transport/src/lib.rs doctest silenced with ignore instead of corrected
The doctest annotation was changed from rust,no_run to rust,ignore. no_run compiles but does not execute — it would have caught AutomergeIrohBackend::new() requiring arguments at compile time. ignore bypasses compilation entirely. The example now contains placeholder comments (/* AutomergeBackend */, /* IrohTransport */) and provides zero compile-time coverage of the API surface.
Action: Update the example to call AutomergeIrohBackend::new(backend, transport) with correctly-typed bindings and restore rust,no_run. If constructing the argument types is impractical in a doc example, remove the example rather than ignoring it — a silently-stale doc example that bypasses compilation is strictly worse than no example.
Addresses 4 of 5 QA findings from the PR-957 review (5a26cee). Finding #4 (ARCH — Federation/Coalition routing fanout semantics) is deferred per the reviewer's own framing ("Do not inline-fix — this is an ADR-territory question") and surfaced to Kit for a design call. [WARNING] #1 — security.proto HierarchyLevel wire-semantic break - Added a documentation block at the enum explicitly mapping the old SQUAD/PLATOON/COMPANY/BATTALION/BRIGADE/DIVISION values to their new CELL/COHORT/FEDERATION/COALITION/(removed) successors. - Called out that value 4 is rebound (BATTALION → COALITION) and values 5–6 will decode as UNSPECIFIED on proto3 deserialization of pre-rename DeviceIdentity records. - Added `reserved 5, 6;` to lock those values against accidental reuse. [WARNING] #2 — Automerge key prefix rename without migration - Added a "Wire-format break" documentation block on AutomergeSummaryStorage explaining that pre-rename squad-summary:* / platoon-summary:* / company-summary:* documents are intentionally orphaned per ADR-066's "discard old state, replay from peers" decision. - Noted Phase 3 must exercise this against fresh stores; pointed at the cell_key/cohort_key/federation_key/coalition_key helpers as the hook point for any future deployment needing pre-rename state migration. [WARNING] #3 — Scope::Federation/Coalition routing untested - Added 4 unit tests covering cell-leader fanout + non-leader self-target for both Federation and Coalition scopes. - Added a header comment flagging that these tests pin the CURRENT implicit-fanout behaviour, NOT the FINAL behaviour (open per #4). [IDIOM] #5 — peat-transport doctest silenced with `ignore` instead of fixed - Rewrote doctest with real Arc<AutomergeBackend> + Arc<IrohTransport> bindings so the example type-checks against AutomergeIrohBackend::new. - Restored `rust,no_run` (gives compile-time coverage, doesn't execute). - Also corrected stale "CAP Transport" / "cap-*" naming in the module doc. Verification: - cargo +stable check --workspace: clean - cargo +stable test -p peat-protocol command::routing::tests: 8/8 pass - cargo +stable test -p peat-transport --doc: 1/1 pass (was `ignore`, now compiles)

Peat QA Review (SHA: f0cc768)
[ARCH] — CommandRouter Federation/Coalition routing conflates tier membership with cell membership
Location: peat-protocol/src/command/routing.rs, Scope::Federation | Scope::Coalition arm
The router's resolve_target falls back to AllCellMembers(self.cell_members.clone()) for both Scope::Federation and Scope::Coalition because the CommandRouter struct carries no federation_id or coalition_id field — only cell_id / cohort_id. The effect is that any Federation- or Coalition-scoped command arriving at a node fans out to that node's cell members, regardless of whether the node is actually a member of the targeted federation or coalition. The behavior is indistinguishable from a cell-scoped broadcast, but the caller believes they issued a higher-tier command.
The PR documents this explicitly (Semantic Decision #1) and pins the current behavior with four new tests, explicitly marking the tests as pinning current behavior rather than intended behavior, and defers the stricter "drop on unknown-tier membership" alternative to ADR-067. The concern is that this implicit fanout could be inadvertently relied upon before ADR-067 lands — at which point changing the semantics becomes a breaking behavior change for any coordinator that has come to depend on the cell-fanout fallback. Escalating rather than proposing a fix, per the [ARCH] policy.
[WARNING] — CoalitionSummary lacks a JSON roundtrip test in peat-schema
Location: peat-schema/tests/json_roundtrip_test.rs
CoalitionSummary is the only net-new proto message in this PR (the other three tier messages are renames). The json_roundtrip_test.rs file was updated to rename the SquadSummary → CellSummary roundtrip test but no equivalent test was added for CoalitionSummary. The existing test_update_coalition_summary_preserves_history_peat903 in automerge_summary_storage.rs verifies CRDT delta-history semantics, but it does not verify the JSON field names and structure that the Ditto CRDT backend requires for OR-Set / LWW-Register merge operations (member_ids, federation_ids, scalar fields). A test_coalition_summary_json_roundtrip in peat-schema/tests/json_roundtrip_test.rs — parallel to the test_cell_summary_json_roundtrip structure — would close this gap before Phase 3 exercises Coalition against a live Ditto mesh.
…cable (peat#904 PR #957 QA #4) Per Kit's design call on QA review finding #4 (ARCH): peat commits to the **coordinator-mediated** dissemination model. Federation- and Coalition-scope commands are resolved at their tier coordinator and re-emitted as Cell- or Individual-scope to specific cells/nodes. A per-cell CommandRouter should never see these scopes inbound. The previous implementation fell back to "fan out cell-locally when the router has no higher-tier membership signal" — silently committing to a fourth dissemination model that no design doc described, and one that amplifies one command into thousands of cell-level broadcasts at Coalition scale (~1000+ peers). This commit: - Updates the `Scope::Federation | Scope::Coalition` arm in `CommandRouter::resolve_target` to return `TargetResolution::NotApplicable` and emit `tracing::warn!` so misrouted higher-tier commands are visible to operators. - Adds a substantial module-level doc-comment spelling out the coordinator-mediated dissemination model: Cell/Cohort scopes use the existing gossip-down-to-cell-leaders path; Federation/Coalition scopes are coordinator-resolved at their tier and never reach per-cell routers under correct operation. - Updates the 4 routing tests (added in commit f0cc768) to assert `NotApplicable` rather than implicit fanout. Test names made explicit about the model: - test_resolve_federation_at_cell_router_is_not_applicable_even_as_leader - test_resolve_federation_at_cell_router_is_not_applicable_for_non_leader - test_resolve_coalition_at_cell_router_is_not_applicable_even_as_leader - test_resolve_coalition_at_cell_router_is_not_applicable_for_non_leader Header comment block updated to document the model and the rejected alternative. Verification: cargo +stable test -p peat-protocol command::routing::tests — 8 passed / 0 failed. This resolves PR #957 QA review finding #4. ADR amendment formalizing the dissemination model belongs to the follow-up doc PR after Phase 4 ships, per ADR-066's stated convention.

Peat QA Review (SHA: 8e680e2)
No findings.
Security primitives — No cryptographic code touched. No non-FIPS primitives introduced. Clean.
Protocol/schema backward compatibility — Intentional, ADR-066-sanctioned break, documented correctly. Field numbers within messages are preserved (binary wire-compat); values 5–6 dropped from HierarchyLevel are explicitly called out in security.proto with the Old→New mapping table and operator upgrade path. Proto files bump to v2.0.0. The JSON/gRPC-JSON key changes (platoonId → cohortId, SQUAD → CELL enum strings, etc.) are a natural consequence of the versioned rename and fully in scope per ADR-066's no-deprecated-aliases policy.
Automerge sync semantics (peat-mesh) — Coalition-tier storage follows the peat#903/peat#896-proven pattern (message_to_automerge_into with existing doc). The test_update_coalition_summary_preserves_history_peat903 regression test mirrors the three prior tiers. Automerge key prefix migration ("orphaned documents, replay from peers") is documented in the storage module comment. No sync-semantic breaks found.
peat-ffi / peat-btle — Not touched. Cross-platform binding analysis N/A for this PR.
Surface-tier E2E coverage — No UniFFI/JNI/BLE/FFI surfaces added or modified. All new Coalition API is internal Rust. CRUD coverage (create-once enforcement, update, get, delete) and the peat#903 history-preservation regression are present for all four storage tiers including Coalition.
Command routing (Scope::Federation/Coalition → NotApplicable) — Design decision is sound and well-documented in the module docstring. The coordinator-mediated dissemination model is the correct choice: fanning out a Federation/Coalition-scope command at every cell-tier router would amplify one command into thousands of cell-level broadcasts at Coalition scale. Four tests cover both leader/non-leader cases at both Federation and Coalition scope. No concern.
TAK bridge consolidation — EchelonLevel → HierarchyLevel correctly fixes the pre-rename bug where Squad and Cell were treated as adjacent distinct levels in the old enum. Filter semantics (CapabilitySummaryOnly top-tier guard, CellLeaderOnly threshold, HierarchicalFiltering viewer-tier logic) are preserved under the new vocabulary. CoT type-string literals correctly left untouched per ADR-066.
peat-transport doctest — Fixed from pre-existing rot; AutomergeIrohBackend::new(backend, transport) now matches the actual constructor signature. Still no_run (cannot construct the full backend in a doctest), which is correct.
Implementation idiom — Production code uses ? for error propagation throughout. unwrap_or(HealthStatus::Failed) fallbacks in health aggregation are intentionally conservative. Clones in delta application helpers are unavoidable (building Vec<FieldUpdate>). No borrow-checker workarounds.
Consumer references — None introduced. Grep gate on the new Coalition code paths is clean.
Summary
Phases 1+2 of the peat#904 workspace rename epic, per ADR-066 (merged in #956).
Folded into one PR by necessity: peat-schema and peat-protocol are workspace siblings and ADR-066 commits to no deprecated aliases — splitting Phase 1 (schema) from Phase 2 (protocol) would leave the workspace uncompilable between merges.
