The implementation keeps the local server as the canonical source of truth, forwards safe local notices and resolutions through an in-process bridge when a relay is connected, ingests remote catch-up and resolution frames once by notice id, and keeps accepted room notices flowing into canonical local announcements. The validation sweep confirmed the session deliverables were present, the targeted server/web/protocol tests passed, and the workspace test run completed successfully. *** ## Deliverables ### Files Created | File | Purpose | Lines | | ------------------------------------------------------------------------------------------------------------------ | -------------------------------------------------------------------------------------------------- | ----- | | `apps/server/src/lib/warRoomNoticeBridge.ts` | Server relay bridge for local sends, remote ingest, catch-up dedupe, provenance, and hydration | \~260 | | `apps/server/tests/warRoomNoticeBridge.test.ts` | Focused server coverage for bridge forwarding, ingest, dedupe, provenance, and standalone behavior | \~360 | | `apps/web/src/lib/noticeBoardApi.ts` | Authenticated local notice-board helper with timeout and compact error mapping | \~180 | | `apps/web/src/lib/warRoomNoticeConvergence.ts` | Web helper for safe room-notice conversion and remote frame convergence | \~220 | | `apps/web/tests/warRoomNoticeConvergence.test.ts` | Focused web coverage for sanitizer, conversion, merge, and blocked payloads | \~260 | | `.spec_system/specs/phase17-session08-local-war-room-bridge-and-room-notice-convergence/IMPLEMENTATION_SUMMARY.md` | Session closeout summary | \~70 | ### Files Modified | File | Changes | | ------------------------------------------------------------------------------------------------ | ---------------------------------------------------------------------------------------- | | `.spec_system/state.json` | Marked the session complete, cleared `current_session`, and appended completion history. | | `.spec_system/PRD/phase_17/PRD_phase_17.md` | Advanced Phase 17 progress to 8/10 and marked Session 08 complete. | | `.spec_system/specs/phase17-session08-local-war-room-bridge-and-room-notice-convergence/spec.md` | Updated session status to Completed. | | `package.json` | Bumped the root patch version to `0.1.123`. | | `README.md` | Updated the version badge to match the new root version. | | `apps/server/src/routes/noticeBoard.ts` | Hooked local posts and resolutions into the bridge-aware path. | | `apps/server/src/ws/handlers.ts` | Preserved hydration while routing post\_notice through the bridge-aware canonical path. | | `apps/server/src/server.ts` | Wired the bridge into the server bootstrap with safe no-op defaults. | | `apps/server/src/managers/noticeBoard.ts` | Added bounded provenance support for remote notice ingestion. | | `apps/web/src/lib/warRoomClient.ts` | Extended the client-side relay helpers used by the War Room convergence path. | | `apps/web/src/store/useWarRoomStore.ts` | Routed accepted room notices through canonical creation and remote frame merge handling. | | `apps/web/tests/WarRoomPanel.test.tsx` | Covered room notice send behavior and sanitization constraints. | | `apps/web/tests/warRoomStore.test.ts` | Covered duplicate-send protection and remote convergence behavior. | | `packages/protocol/src/warroom.ts` | Added shared helper support for room-notice conversion vocabulary. | | `packages/protocol/tests/warroomNoticeRelay.test.ts` | Extended protocol coverage for the relay helper path. | *** ## Technical Decisions 1. **Canonical local state stays authoritative**: the server remains the source of truth, and relay traffic is treated as an optional coordination channel. 2. **Remote frames are deduped by notice id**: this keeps catch-up and relay replays from reintroducing the same coordination message into local state. 3. **Accepted room notices become canonical announcements**: the web panel preserves the input affordance while still flowing through the local board. *** ## Test Results | Metric | Value | | -------- | -------------------------------------------------------- | | Tests | `npm test` plus focused server, web, and protocol suites | | Passed | `2494` workspace tests passed, `1` skipped | | Coverage | Not measured in this session | *** ## Lessons Learned 1. Keep the local server as the canonical source and bridge outward only when relay connectivity is explicitly present. 2. Make remote ingest fail closed and bounded so provenance and dedupe stay predictable. *** ## Future Considerations Items for future sessions: 1. Implement the automatic mission lifecycle notice posts in Session 09. 2. Finish the validation documentation and handoff package in Session 10. *** ## Session Statistics * **Tasks**: 24 completed * **Files Created**: 6 * **Files Modified**: 15 * **Tests Added**: 3 focused suites plus workspace verification * **Blockers**: 0 resolved --- # Agent Instructions This documentation is published with GitBook.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter: ``` GET https://faction-os.gitbook.io/faction-os-docs/.spec_system/archive/sessions/phase17-session08-local-war-room-bridge-and-room-notice-convergence/implementation_summary.md?ask=&goal= ``` `ask` is the immediate question: it should be specific, self-contained, and written in natural language. `goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal. The response will contain a direct answer to the question and relevant excerpts and sources from the documentation. Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
