### Task T001 - Review canonical Notice Board manager ingest, batch ingest, resolution, active-room, and debug behavior

**Started**: 2026-06-05 23:13 **Completed**: 2026-06-05 23:15 **Duration**: 2 minutes

**Notes**:

* Reviewed canonical manager state, post, list, ingest, ingestBatch, resolveForRoom, active-room defaulting, persistence, and context cache behavior.
* Confirmed manager dedupes remote ingest by notice id and resolves by room-scoped id lookup.

**Files Changed**:

* None - review task only.

***

### Task T002 - Review Notice Board REST and WebSocket post/resolve emit paths for bridge injection points

**Started**: 2026-06-05 23:13 **Completed**: 2026-06-05 23:15 **Duration**: 2 minutes

**Notes**:

* Reviewed canonical REST post, compatibility post, resolve routes, local broadcast helpers, and WebSocket `post_notice` path.
* Identified post/resolve bridge injection points after canonical manager success and before route response completion.

**Files Changed**:

* None - review task only.

***

### Task T003 - Review War Room panel room-notice send flow, in-flight guards, local auth helpers, and Worker frame handling

**Started**: 2026-06-05 23:13 **Completed**: 2026-06-05 23:15 **Duration**: 2 minutes

**Notes**:

* Reviewed panel form affordance, store `noticeSend` in-flight guard, local auth helper, Worker connection client, and remote event/catch-up handling.
* Confirmed local Notice Board state already merges canonical server events through `useGameStore`.

**Files Changed**:

* None - review task only.

***

### Task T004 - Review Worker Notice Board relay contracts and existing protocol tests before adding local convergence behavior

**Started**: 2026-06-05 23:13 **Completed**: 2026-06-05 23:15 **Duration**: 2 minutes

**Notes**:

* Reviewed Worker frame vocabulary, parser behavior for `notice_board_message`, `notice_resolved`, `notice_board_catchup`, and existing relay tests.
* Confirmed protocol already exposes safe Notice Board relay contracts, so no shared helper is required unless web conversion duplicates grow.

**Files Changed**:

* None - review task only.

***

### Task T005 - Create local Notice Board bridge scaffold with injected relay sender, active-room resolver, clock, and disconnected no-op mode

**Started**: 2026-06-05 23:15 **Completed**: 2026-06-05 23:24 **Duration**: 9 minutes

**Notes**:

* Added `WarRoomNoticeBridge` with injected Notice Board manager, broadcaster, relay sender, connected-state snapshot, active-room resolver, clock, and send timeout.
* Default behavior is disconnected no-op unless a sender and connected snapshot are supplied.

**Files Changed**:

* `apps/server/src/lib/warRoomNoticeBridge.ts` - bridge scaffold, outbound sender wrapper, and standalone defaults.

**BQC Fixes**:

* External dependency resilience: relay sends are bounded by a timeout and return compact failures.
* Duplicate action prevention: outbound notice and resolution sends use in-flight keys.

***

### Task T006 - Define bridge input handling for remote message, resolution, catch-up, and room-notice frames

**Started**: 2026-06-05 23:15 **Completed**: 2026-06-05 23:24 **Duration**: 9 minutes

**Notes**:

* Remote frames parse through protocol validators before manager mutation.
* Malformed, unsupported, wrong-room, unknown-id, and duplicate inputs map to compact result codes without raw payload logging.

**Files Changed**:

* `apps/server/src/lib/warRoomNoticeBridge.ts` - remote frame ingestion methods and explicit result mapping.

**BQC Fixes**:

* Trust boundary enforcement: Worker-origin frames are schema parsed before mutation.
* Error information boundaries: returned failures use stable codes and generic messages only.

***

### Task T007 - Add bounded remote provenance model and debug accessor

**Started**: 2026-06-05 23:15 **Completed**: 2026-06-05 23:24 **Duration**: 9 minutes

**Notes**:

* Added manager-owned in-memory provenance keyed by notice id with source, ingested time, source machine id, and source participant id only.
* Provenance prunes when notices leave the bounded manager set and is exposed only through debug accessors/routes.

**Files Changed**:

* `apps/server/src/managers/noticeBoard.ts` - provenance map, debug accessor, `hasNotice`, clone, and prune helpers.
* `apps/server/src/routes/noticeBoard.ts` - debug list response includes provenance for returned messages only.

**BQC Fixes**:

* Error information boundaries: provenance excludes raw Worker payloads and broad diagnostic content.
* Resource cleanup: `destroy()` clears provenance with other manager-owned caches.

***

### Task T010 - Add shared room-notice conversion vocabulary

**Started**: 2026-06-05 23:15 **Completed**: 2026-06-05 23:24 **Duration**: 9 minutes

**Notes**:

* Added protocol-owned conversion from safe `warroom_room_notice` frames to canonical `announcement` create requests.
* This avoids duplicated level-to-priority/severity mapping between server and web convergence code.

**Files Changed**:

* `packages/protocol/src/warroom.ts` - room-notice announcement helper and level mapping helpers.

**BQC Fixes**:

* Contract alignment: shared helper keeps server and web mapping consistent with protocol types.

***

### Task T008 - Create local Notice Board API helper

**Started**: 2026-06-05 23:24 **Completed**: 2026-06-05 23:30 **Duration**: 6 minutes

**Notes**:

* Added an authenticated local `/notice-board` POST helper with timeout, compact error mapping, and response validation through protocol notice parsing.
* Reused the existing local API URL resolver and local auth header helper.

**Files Changed**:

* `apps/web/src/lib/noticeBoardApi.ts` - Notice Board POST helper and compact result types.

**BQC Fixes**:

* External dependency resilience: requests use an abort timeout.
* Failure path completeness: offline, timeout, HTTP, bad response, and invalid input map to caller-visible failures.

***

### Task T009 - Create War Room Notice Board convergence helper

**Started**: 2026-06-05 23:24 **Completed**: 2026-06-05 23:30 **Duration**: 6 minutes

**Notes**:

* Added pure conversion for safe room-notice input to canonical announcement requests.
* Added pure Worker Notice Board frame conversion to canonical local `ServerEvent` payloads for message, resolution, and catch-up frames.

**Files Changed**:

* `apps/web/src/lib/warRoomNoticeConvergence.ts` - room-notice conversion and Worker frame merge preparation.

**BQC Fixes**:

* Contract alignment: Worker frames parse through protocol validators and merge through existing local Notice Board event shapes.
* Error information boundaries: merge failures expose compact copy without raw frame data.

***

### Task T011 - Wire canonical local post flow to bridge outbound `notice_board_message`

**Started**: 2026-06-05 23:15 **Completed**: 2026-06-05 23:24 **Duration**: 9 minutes

**Notes**:

* REST canonical and compatibility post routes now notify the bridge after the manager accepts and local broadcast is emitted.
* Existing success response shapes are unchanged; optional relay failures emit compact local toast feedback.

**Files Changed**:

* `apps/server/src/routes/noticeBoard.ts` - bridge dependency and post forwarding.

**BQC Fixes**:

* Duplicate action prevention: existing post in-flight guard remains in place before bridge send.
* Failure path completeness: relay failure is caller-visible over local WebSocket toast.

***

### Task T012 - Wire canonical local resolve flow to bridge outbound `notice_resolved`

**Started**: 2026-06-05 23:15 **Completed**: 2026-06-05 23:24 **Duration**: 9 minutes

**Notes**:

* Resolve route forwards accepted canonical resolutions through the bridge.
* Added room-scoped resolution in-flight guard while preserving existing success response shape.

**Files Changed**:

* `apps/server/src/routes/noticeBoard.ts` - resolution in-flight guard and bridge forwarding.

**BQC Fixes**:

* Duplicate action prevention: concurrent duplicate resolve requests return 409.
* Failure path completeness: relay failure emits compact toast without undoing canonical local resolution.

***

### Task T013 - Wire WebSocket `post_notice` compatibility path through bridge-aware canonical posting

**Started**: 2026-06-05 23:15 **Completed**: 2026-06-05 23:24 **Duration**: 9 minutes

**Notes**:

* WebSocket `post_notice` still posts through the canonical manager and broadcasts locally.
* Bridge forwarding is attached after local broadcast; relay failures send a compact toast to the originating socket.

**Files Changed**:

* `apps/server/src/ws/handlers.ts` - bridge dependency and WebSocket forwarding helper.

**BQC Fixes**:

* Failure path completeness: async relay failures are caught and reported to the socket.
* State freshness on re-entry: existing connection hydration remains unchanged.

***

### Task T014 - Implement remote `notice_board_message` ingest into the canonical manager

**Started**: 2026-06-05 23:15 **Completed**: 2026-06-05 23:24 **Duration**: 9 minutes

**Notes**:

* Remote message frames ingest once by notice id, preserve active room scope, record bounded provenance, and emit canonical local `notice_board_message`.

**Files Changed**:

* `apps/server/src/lib/warRoomNoticeBridge.ts` - remote message ingest.

**BQC Fixes**:

* Trust boundary enforcement: protocol parser validates frame and notice shape before ingest.
* Concurrency safety: manager id dedupe prevents duplicate accepted messages.

***

### Task T015 - Implement remote `notice_resolved` ingest for the active room

**Started**: 2026-06-05 23:15 **Completed**: 2026-06-05 23:24 **Duration**: 9 minutes

**Notes**:

* Remote resolution frames resolve active-room notices and emit canonical local `notice_resolved`.
* Unknown notice ids and wrong-room frames are explicit no-op results.

**Files Changed**:

* `apps/server/src/lib/warRoomNoticeBridge.ts` - remote resolution ingest.

**BQC Fixes**:

* Contract alignment: resolution aliases are parsed through protocol helpers.
* Failure path completeness: malformed, unknown, and wrong-room paths return explicit compact codes.

***

### Task T016 - Implement remote `notice_board_catchup` batch ingest

**Started**: 2026-06-05 23:15 **Completed**: 2026-06-05 23:24 **Duration**: 9 minutes

**Notes**:

* Catch-up arrays parse through protocol bounds, skip wrong-room and duplicate ids, batch ingest deterministic notices, and emit one local hydrate after accepted changes.

**Files Changed**:

* `apps/server/src/lib/warRoomNoticeBridge.ts` - catch-up ingest and hydrate broadcast.

**BQC Fixes**:

* Duplicate action prevention: existing and intra-batch ids are skipped before ingest.
* Contract alignment: catch-up ordering and bounds come from the protocol parser.

***

### Task T017 - Instantiate and inject the bridge with standalone no-op defaults

**Started**: 2026-06-05 23:15 **Completed**: 2026-06-05 23:24 **Duration**: 9 minutes

**Notes**:

* Server startup constructs a bridge with local-room no-op defaults and injects it into REST and WebSocket handlers.
* No local Worker proxy routes were added.

**Files Changed**:

* `apps/server/src/server.ts` - bridge construction, optional runtime relay injection, route/WebSocket injection.

**BQC Fixes**:

* State freshness on re-entry: default bridge remains disconnected unless runtime relay state says otherwise.
* Trust boundary enforcement: server route surface remains local Notice Board only.

***

### Task T018 - Route War Room panel safe room-notice send through canonical `/notice-board`

**Started**: 2026-06-05 23:24 **Completed**: 2026-06-05 23:30 **Duration**: 6 minutes

**Notes**:

* `sendRoomNotice` now validates the safe Worker frame, posts the canonical local announcement, applies the accepted Notice Board response locally, then revalidates the Worker connection before external send.
* Connection close/connect paths reset stale `lastNoticeSentAt` state.

**Files Changed**:

* `apps/web/src/store/useWarRoomStore.ts` - canonical post, local event merge, and re-entry revalidation.

**BQC Fixes**:

* State freshness on re-entry: Worker connection and room state are checked again after the local POST completes.
* Failure path completeness: local post failures are surfaced and stop external Worker send.

***

### Task T019 - Merge Worker Notice Board relay frames into Notice Board state

**Started**: 2026-06-05 23:24 **Completed**: 2026-06-05 23:30 **Duration**: 6 minutes

**Notes**:

* Direct Worker `notice_board_message`, `notice_resolved`, and `notice_board_catchup` frames now merge through `useGameStore.applyEvent`.
* Recent-event catch-up batches merge Notice Board frames while non-Notice-Board context still updates existing War Room remote context summaries.

**Files Changed**:

* `apps/web/src/store/useWarRoomStore.ts` - Notice Board convergence application in socket frame handling.
* `apps/web/src/lib/warRoomClient.ts` - accepts direct `notice_board_catchup` socket frames.

**BQC Fixes**:

* Contract alignment: all relay frames merge through canonical Notice Board event helpers instead of remote-only state.
* Failure path completeness: failed convergence aborts the frame state update and surfaces compact error state.

***

### Task T020 - Preserve blocked-input copy, disconnected feedback, and Worker send behavior

**Started**: 2026-06-05 23:24 **Completed**: 2026-06-05 23:30 **Duration**: 6 minutes

**Notes**:

* Existing panel form copy and blocked-input feedback remain unchanged.
* Disconnected feedback still fires before local posting, and successful accepted input still sends the validated Worker frame after local canonical post.

**Files Changed**:

* `apps/web/src/store/useWarRoomStore.ts` - preserved disconnected guard and Worker send path around added local post.
* `apps/web/src/components/WarRoomPanel.tsx` - no source change required.
* `apps/web/src/lib/warRoomFederation.ts` - no source change required.

**BQC Fixes**:

* Duplicate action prevention: existing `noticeSend` in-flight guard remains authoritative.
* Accessibility and platform compliance: panel controls were not structurally changed.

***

### Task T022 - Add web convergence and store tests

**Started**: 2026-06-05 23:30 **Completed**: 2026-06-05 23:36 **Duration**: 6 minutes

**Notes**:

* Added pure convergence tests for announcement conversion, blocked input, message/resolution/catch-up event conversion, mixed recent-event batches, and blocked payload non-application.
* Extended store tests to assert canonical local POST, duplicate send guard, blocked input, and direct Worker Notice Board frame merges.

**Files Changed**:

* `apps/web/tests/warRoomNoticeConvergence.test.ts` - convergence helper tests.
* `apps/web/tests/warRoomStore.test.ts` - canonical post and relay frame merge tests.

**BQC Fixes**:

* Failure path completeness: test verifies blocked payloads do not partially apply local state.

***

### Task T023 - Add War Room panel tests

**Started**: 2026-06-05 23:30 **Completed**: 2026-06-05 23:36 **Duration**: 6 minutes

**Notes**:

* Updated panel tests to assert accepted room notices post canonical announcements, preserve Worker socket send, retain blocked-input copy, and surface failed local post feedback.

**Files Changed**:

* `apps/web/tests/WarRoomPanel.test.tsx` - panel behavior coverage for canonical posting and failure feedback.

**BQC Fixes**:

* Failure path completeness: UI test covers failed local post feedback.
