The server exposes a count-only diagnostics route, and hook/listener logs now emit safe summaries only. Recovery is limited to stale listener PID files and malformed spool entries, with explicit opt-in and idempotent handling. *** ## Deliverables ### Files Created | File | Purpose | Lines | | ------------------------------------------------------------------------------------------------------ | -------------------------------------------------------------------------------------- | ----- | | `apps/server/src/lib/orchestrationDiagnostics.ts` | Build count-only orchestration diagnostics snapshots | \~140 | | `apps/server/src/routes/diagnostics.ts` | Serve the local diagnostics snapshot behind existing middleware | \~80 | | `apps/cli/src/lib/orchestrationDiagnostics.js` | CLI diagnostics helpers with loopback-only HTTP, auth forwarding, and bounded failures | \~220 | | `apps/cli/tests/orchestrationDiagnostics.test.js` | CLI diagnostics and recovery coverage | \~240 | | `apps/server/tests/orchestrationDiagnostics.test.ts` | Server diagnostics route coverage | \~180 | | `apps/hooks/tests/orchestrationDiagnostics.test.js` | Hook and listener diagnostics coverage | \~180 | | `.spec_system/specs/phase03-session06-cli-diagnostics-and-recovery-controls/validation.md` | Final validation record | \~180 | | `.spec_system/specs/phase03-session06-cli-diagnostics-and-recovery-controls/IMPLEMENTATION_SUMMARY.md` | Session closeout summary | \~120 | ### Files Modified | File | Changes | | ------------------------------------------- | ----------------------------------------------------------------- | | `.spec_system/state.json` | Marked the session complete and updated completion history | | `.spec_system/PRD/phase_03/PRD_phase_03.md` | Advanced Phase 03 progress to 6/7 and marked Session 06 complete | | `package.json` | Bumped the project patch version | | `apps/cli/src/commands/status.js` | Printed compact orchestration posture and fallback states | | `apps/cli/src/commands/doctor.js` | Added diagnostics checks and explicit recovery mode | | `apps/cli/src/index.js` | Documented the diagnostics and recovery help text | | `apps/cli/src/lib/localFiles.js` | Added stale PID and malformed spool recovery helpers | | `apps/cli/tests/cliRuntime.test.js` | Added fake diagnostics route coverage for the CLI runtime harness | | `apps/hooks/src/_lib.js` | Added safe hook diagnostic summaries | | `apps/hooks/src/ws-listener.js` | Added safe listener diagnostics and bounded summaries | | `apps/server/src/server.ts` | Wired the diagnostics route into server creation | | `apps/cli/README_cli.md` | Documented diagnostics and recovery boundaries | | `apps/hooks/README_hooks.md` | Documented safe diagnostics and quiet-failure behavior | | `apps/server/README_server.md` | Documented the diagnostics route and auth inheritance | | `docs/api/README_api.md` | Documented the diagnostics route in the API reference | *** ## Technical Decisions 1. **Count-only diagnostics**: The server route reports counts, state labels, and availability rather than raw manager payloads to keep privacy boundaries intact. 2. **Explicit recovery flag**: Recovery is opt-in and confined to stale listener PID files and malformed spool entries so diagnostics never become hidden cleanup or erase behavior. 3. **Safe summaries in hooks**: Hook and listener logs use sanitized identifiers and bounded metadata so raw prompts, commands, paths, and payloads do not leak into log output. *** ## Test Results | Metric | Value | | ------------- | ----------------------------------------------------------- | | Vitest | 27 files passed / 227 tests passed | | Typecheck | `npm --workspace apps/server run typecheck` passed | | Biome | Focused check on touched source, test, and doc files passed | | Patch Hygiene | `git diff --check` passed | *** ## Lessons Learned 1. The orchestration diagnostics boundary needs to stay narrow or the CLI quickly drifts into raw state dumping. 2. Recovery flows are safest when they are explicit, idempotent, and confined to a small, well-defined file set. *** ## Future Considerations Items for future sessions: 1. Keep Phase 03 validation aligned if the diagnostics surface grows or new local health checks are added. 2. Revalidate the privacy and recovery boundaries if any later session expands orchestration scope. *** ## Session Statistics * **Tasks**: 24 completed * **Files Created**: 8 * **Files Modified**: 15 * **Tests Added**: 3 * **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/phase03-session06-cli-diagnostics-and-recovery-controls/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.
