The work added server-owned workpads, evidence metadata, verification retries/skips, review-gate decisions, compact artifact events, attention side effects, web panel rendering, linked drawer details, store reconciliation, and documentation while preserving the raw-content blocking boundary. *** ## Deliverables ### Files Created | File | Purpose | Lines | | ----------------------------------------------------------------- | ----------------------------------------------------------------------------- | ----- | | `apps/server/src/lib/missionArtifacts.ts` | Safe artifact derivation, target links, retry policy, and attention helpers | 630 | | `apps/web/src/lib/missionArtifacts.ts` | Web artifact view models, progress chips, linked records, and blocked labels | 387 | | `apps/web/src/components/orchestration/MissionArtifactsPanel.tsx` | Product-facing Mission Artifacts panel states and linked artifact rows | 154 | | `apps/server/tests/commandCenterMissionArtifacts.test.ts` | Server manager, route, WebSocket, retry, review, and attention coverage | 520 | | `apps/web/tests/missionArtifacts.test.ts` | Web helper, store reducer, malformed event, and raw-content blocking coverage | 387 | ### Files Modified | File | Changes | | --------------------------------------------------------------- | ---------------------------------------------------------------------------------------------------- | | `.spec_system/state.json` | Added Session 10 planned, validated, and completed history plus completed-session tracking | | `.spec_system/PRD/phase_19/PRD_phase_19.md` | Marked Session 10 complete and updated phase progress to 10/16 | | `apps/server/src/managers/orchestrationCommandCenter.ts` | Added artifact mutation, retry/skip, review-decision, attention, and event behavior | | `apps/server/src/routes/commandCenter.ts` | Added local artifact and review mutation routes | | `apps/server/src/lib/commandCenterValidation.ts` | Added bounded artifact action parsing and nested mutation envelope support | | `apps/web/src/lib/orchestrationApi.ts` | Added artifact mutation clients and duplicate-trigger guards | | `apps/web/src/store/useGameStore.ts` | Added artifact event merge reconciliation and stale drawer cleanup | | `apps/web/src/components/orchestration/CommandCenterPanes.tsx` | Wired Mission Artifacts into Orchestration panes | | `apps/web/src/components/orchestration/OrchestrationDrawer.tsx` | Added linked artifact details with safe metadata only | | `apps/web/src/components/orchestration/OrchestrationShell.tsx` | Included artifact event handling in the shell wiring | | `apps/web/tests/OrchestrationPanel.test.tsx` | Added Mission Artifacts panel and drawer UI coverage | | `docs/api/README_api.md` | Documented artifact routes, WebSocket frames, retry/skip, review decisions, and raw-content blocking | | `apps/server/README_server.md` | Documented server artifact ownership and route behavior | | `apps/web/README_web.md` | Documented Mission Artifacts panel behavior and privacy boundary | | `README.md` | Updated the root version badge from 0.1.157 to 0.1.158 | | `package.json` | Bumped root version from 0.1.157 to 0.1.158 | | `package-lock.json` | Synchronized root lockfile version from 0.1.157 to 0.1.158 | *** ## Technical Decisions 1. **Manager-owned artifact state**: Kept workpad, evidence, verification, and review transitions behind the server command-center manager so revision checks, idempotency, event emission, and attention updates stay in one boundary. 2. **Metadata-only broad surfaces**: Blocked raw prompts, diffs, terminal output, file contents, transcripts, tokens, logs, and unsafe paths from artifact panels and docs, using safe labels and compact metadata instead. 3. **Merged compact events over hydrated records**: WebSocket artifact updates now preserve hydrated record details when compact frames arrive. 4. **Retry history includes skipped attempts**: Retry ids count all same-target attempts so skipped verification history cannot be overwritten. *** ## Test Results | Metric | Value | | --------------- | ---------------------------------- | | Focused Tests | 25 passed / 25 | | Full Test Files | 237 passed / 238, 1 skipped | | Full Tests | 2841 passed / 2842, 1 skipped | | Failed | 0 | | Coverage | Not reported by configured command | *** ## Lessons Learned 1. Compact artifact events must merge over hydrated state or live updates can erase useful detail fields. 2. Target-scoped drawer links need to filter verification and review gates before deriving evidence links. 3. Retry-limit accounting must include skipped attempts to preserve the audit trail. *** ## Future Considerations Items for future sessions: 1. Connect Mission Artifacts to template and planning-context surfaces in Session 11. 2. Reuse artifact progress chips for terminal/container execution evidence in Session 12. 3. Keep raw artifact contents out of broad collaboration and handoff surfaces in Sessions 13 and 14. *** ## Session Statistics * **Tasks**: 18 completed * **Files Created**: 5 implementation/test files plus 1 implementation summary * **Files Modified**: 16 tracked files * **Tests Added**: 6 focused test groups across server, store, helper, and UI coverage * **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/phase19-session10-mission-artifacts/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.
