The result keeps collaboration optional and local-first while making stale, duplicate, expired, mismatched, malformed, and replayed authority inputs fail deterministically. *** ## Deliverables ### Files Created | File | Purpose | Lines | | ------------------------------------------------------------------------------------------------------------------ | --------------------------------------------------------------------------- | ----- | | `apps/warroom/src/authority.ts` | Room-local authority issue, verify, expiration, rotation, and replay helper | \~220 | | `apps/warroom/tests/authority.test.ts` | Focused authority helper tests | \~180 | | `.spec_system/specs/phase06-session02-room-authority-and-participant-identity-contracts/IMPLEMENTATION_SUMMARY.md` | Session closeout summary | \~60 | ### Files Modified | File | Changes | | ------------------------------------------------------------------------------------------------ | ------------------------------------------------------------------------------------------- | | `packages/protocol/src/warroom.ts` | Added authority, revision, expiration, idempotency, and error contracts plus validators | | `packages/protocol/tests/warroom.test.ts` | Added protocol authority contract and parser coverage | | `apps/warroom/src/index.ts` | Enforced authority for create, join, approve, reject, snapshot, socket, and reconnect flows | | `apps/warroom/tests/warroom.test.ts` | Extended Worker lifecycle coverage for authority failure paths | | `apps/web/src/lib/warRoomClient.ts` | Added authority-aware REST and socket handling plus failure mapping | | `apps/web/src/lib/warRoomIdentity.ts` | Kept browser display hints separate from authority state | | `apps/web/src/store/useWarRoomStore.ts` | Tracked authority status, revision, expiration, and revalidation behavior | | `apps/web/src/lib/warRoomUi.ts` | Added bounded authority copy and labels | | `apps/web/src/components/WarRoomPanel.tsx` | Displayed authority status and failure feedback accessibly | | `apps/web/tests/warRoomClient.test.ts` | Added client authority success and error mapping tests | | `apps/web/tests/warRoomStore.test.ts` | Added store authority, stale hydration, duplicate, reconnect, and failure tests | | `apps/web/tests/WarRoomPanel.test.tsx` | Added accessible authority state and failure tests | | `packages/protocol/README_protocol.md` | Documented protocol authority ownership and proof limits | | `apps/warroom/README_warroom.md` | Documented Worker authority behavior and non-hosted identity limits | | `apps/web/README_web.md` | Documented browser authority state and stale-state behavior | | `docs/api/README_api.md` | Documented authority-aware Worker API shapes and compact errors | | `docs/privacy-and-security.md` | Updated data inventory and transfer boundary for authority metadata | | `docs/runbooks/war-room-operations.md` | Updated operational notes for authority failures and non-erasure limits | | `.spec_system/state.json` | Marked the session complete and cleared the active session | | `.spec_system/PRD/phase_06/PRD_phase_06.md` | Updated phase progress and session tracker | | `.spec_system/specs/phase06-session02-room-authority-and-participant-identity-contracts/spec.md` | Marked the session spec complete | | `package.json` | Bumped the project patch version | *** ## Technical Decisions 1. **Protocol-first authority contracts**: Shared authority, revision, expiration, idempotency, and error shapes were added in `packages/protocol` before Worker and web consumers. 2. **Room-local proof only**: The Worker issues opaque authority tokens scoped to a room, participant, role, revision, and expiration without introducing hosted identity or account-backed proof. 3. **Bounded client feedback**: The web client and UI surface map authority failures to short user-safe copy and do not echo raw tokens or request bodies. *** ## Test Results | Metric | Value | | -------- | ------------------------------------------ | | Tests | 79 focused tests plus the repository suite | | Passed | All focused tests and `npm test` passed | | Coverage | Not measured in this closeout summary | *** ## Lessons Learned 1. Revision and idempotency metadata need to travel with authority from protocol through the Worker and into the browser state. 2. Duplicate decision and reconnect flows are simpler to reason about when stale authority is explicitly rejected instead of inferred. *** ## Future Considerations Items for future sessions: 1. Expand shared collaboration event contracts in the next phase session. 2. Keep hosted identity, hosted storage, analytics, and trusted erasure deferred until later phase ownership. *** ## Session Statistics * **Tasks**: 24 completed * **Files Created**: 3 * **Files Modified**: 18 * **Tests Added**: 5 * **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/phase06-session02-room-authority-and-participant-identity-contracts/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.
