The protocol now owns explicit safe collaboration frame families, blocked-field and sensitive-value validation, recent-event parsing, catch-up envelopes, and compact family summaries. The Worker relay consumes those contracts for authority-bound ingest, sender-excluded broadcast, bounded persistence, and legacy unsafe catch-up filtering. The web client and store keep inbound remote context isolated from local source-of-truth state and only send redacted safe frames. *** ## Deliverables ### Files Created | File | Purpose | Lines | | ----------------------------------------------------------------------------------------------------- | ------------------------ | ----- | | `.spec_system/specs/phase06-session03-shared-collaboration-event-contracts/IMPLEMENTATION_SUMMARY.md` | Session closeout summary | \~90 | ### Files Modified | File | Changes | | --------------------------------------------------------------------------------------------------- | -------------------------------------------------------------------------------------- | | `packages/protocol/src/warroom.ts` | Added shared safe-frame, blocked-field, recent-event, catch-up, and summary helpers. | | `packages/protocol/tests/warroom.test.ts` | Added coverage for allowlists, blocked values, ping handling, and catch-up parsing. | | `packages/protocol/README_protocol.md` | Documented collaboration contract ownership and blocked payload categories. | | `apps/warroom/src/index.ts` | Hardened socket ingest, sender exclusion, persistence, and catch-up filtering. | | `apps/warroom/tests/warroom.test.ts` | Added Worker regression coverage for malformed, unsafe, and legacy catch-up frames. | | `apps/warroom/README_warroom.md` | Documented Worker collaboration behavior and catch-up limits. | | `apps/web/src/lib/warRoomClient.ts` | Tightened socket frame parsing and failure mapping. | | `apps/web/src/lib/warRoomFederation.ts` | Refined outbound frame building, inbound merge, summaries, and pruning. | | `apps/web/src/store/useWarRoomStore.ts` | Kept remote context isolated during send, catch-up, reconnect, leave, and reset flows. | | `apps/web/src/components/WarRoomPanel.tsx` | Kept collaboration summary accessible and free of raw payload wording. | | `apps/web/tests/warRoomClient.test.ts` | Added client send and receive safety tests. | | `apps/web/tests/warRoomFederation.test.ts` | Added outbound, inbound, catch-up, pruning, and summary tests. | | `apps/web/tests/warRoomStore.test.ts` | Added store tests for remote-context isolation and duplicate-send guards. | | `apps/web/tests/WarRoomPanel.test.tsx` | Added visible summary coverage for safe family labels. | | `apps/web/README_web.md` | Documented browser remote-context separation and collaboration limits. | | `docs/api/README_api.md` | Documented safe collaboration frames, socket errors, and catch-up limits. | | `docs/privacy-and-security.md` | Updated transfer-boundary guidance for persisted collaboration frames. | | `docs/runbooks/war-room-operations.md` | Added operational guidance for blocked frames and catch-up triage. | | `.spec_system/specs/phase06-session03-shared-collaboration-event-contracts/implementation-notes.md` | Recorded implementation evidence and validation closeout. | | `.spec_system/specs/phase06-session03-shared-collaboration-event-contracts/security-compliance.md` | Recorded the security and privacy review. | *** ## Technical Decisions 1. **Protocol-owned parsing and filtering**: Shared contract parsing reduced drift between the Worker relay and browser consumers. 2. **Compact remote context only**: Summaries and inbound state stayed limited to family labels, counts, and bounded safe context to avoid leaking local workflow data. *** ## Test Results | Metric | Value | | -------- | ---------------------- | | Tests | 2062 passed, 1 skipped | | Passed | 2062 | | Coverage | Not measured | *** ## Lessons Learned 1. Revalidating catch-up payloads at the protocol boundary keeps Worker and web behavior aligned. 2. Remote collaboration UI needs explicit isolation from local source-of-truth state to keep the cockpit trustworthy. *** ## Future Considerations Items for future sessions: 1. Collaborative cockpit UX still needs the session 04 remote-context and desktop/mobile presentation work. 2. Hosted identity, hosted storage, analytics, public replay hosting, remote execution, mobile certification, and trusted erasure remain deferred. *** ## Session Statistics * **Tasks**: 23 completed * **Files Created**: 3 * **Files Modified**: 18 * **Tests Added**: 6 * **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-session03-shared-collaboration-event-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.
