The work adds bounded command-center collaboration contracts, server-owned Notice linkback and handoff readiness behavior, compact War Room relay posture, and a product-facing web Federation/Handoff workbench while preserving local ownership and redaction boundaries. *** ##

Technical Decisions 1. **Protocol-first collaboration contracts**: Shared DTOs and parser guards now define visibility labels, handoff readiness, resume source, lineage, Notice links, remote summary, and posture data before server or web code consumes them. 2. **Server-owned handoff lifecycle**: Scaffold, validation, secret-scan status, staleness, branch/file-state, resume-source, and lineage behavior live in a manager instead of being assembled in routes or UI. 3. **Bounded Notice linkbacks**: Context Notice records carry target kind, ids, labels, and safe related context only; raw prompts, command bodies, transcripts, terminal output, file contents, and broad paths remain blocked. 4. **Summary-only War Room and remote posture**: Relay and remote-access state is exposed through compact labels and counts without tunnel creation, hosted identity claims, or sensitive control-plane data. *** ## Test Results | Metric | Value | | ------------- | ----------------------------------------------------------------- | | Focused Tests | 128 passed | | Full Tests | 2,899 passed, 1 skipped | | Coverage | Statements 77.86%; branches 68.4%; functions 85.72%; lines 83.23% | | Typecheck | PASS | | Format | PASS | | Lint | PASS | | ASCII/LF | PASS | | Security | PASS | *** ## Lessons Learned 1. Collaboration linkbacks need stable Notice ids before request construction so stored records, command-center events, and WebSocket frames agree. 2. UI duplicate-trigger guards are stronger when the same stable key is used for client mutation tracking and server idempotency. 3. Hydration frame order documentation must be updated together with server WebSocket behavior when a new compact frame family is added. *** ## Future Considerations Items for future sessions: 1. Session 14 should build channels and scope on top of the same bounded link and posture metadata instead of introducing parallel collaboration state. 2. Session 15 should reuse collaboration posture events for notification and metrics rollups without expanding remote payload scope. 3. Trusted erasure, hosted identity, broad remote collaboration, and tunnel control remain no-claim boundaries until separately scoped, threat-modeled, tested, and documented. *** ## Session Statistics * **Tasks**: 24 completed * **Files Created**: 15, including 8 runtime/test deliverables and 7 session artifacts * **Files Modified**: 40 tracked files before updateprd metadata * **Tests Added**: 4 new test files plus expanded protocol, server, War Room, and web coverage * **Blockers**: 0 unresolved --- # 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/phase19-session13-collaboration-and-handoff/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.
