The work adds POST `/__hermes_moa_save`, strict payload validation before filesystem access, safe config backup and atomic replacement behavior, typed browser parser contracts, and a `useHermesAdmin().moa.savePreset` hook action without adding visible Ministry UI. *** ## Deliverables ### Files Created | File | Purpose | Lines | | ---- | ------------------------------------------- | ----- | | None | No new production source file was required. | 0 | ### Files Modified | File | Changes | | --------------------------------------------------------------------------------- | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- | | `scripts/lib/hermes-admin-bridge.ts` | Added MoA save endpoint registration, payload validation, config read/backup/merge/write helpers, controlled setup/write errors, and browser-safe response shape. | | `scripts/lib/__tests__/hermes-admin-bridge.test.ts` | Added coverage for route gates, invalid payloads, setup-required config, invalid YAML/root, backup/write failures, merge preservation, default preset updates, and no raw path leakage. | | `src/lib/hermes-admin-types.ts` | Added MoA save request/response contracts, `setup_required` error-code support, and strict response parser. | | `src/lib/__tests__/hermes-admin-types.test.ts` | Added parser coverage for valid MoA save responses, malformed responses, and setup-required bridge errors. | | `src/hooks/use-hermes-admin.ts` | Added `moa.savePreset`, mutation state, cache invalidation, and duplicate in-flight prevention. | | `src/hooks/__tests__/use-hermes-admin.test.tsx` | Added hook coverage for serialization, disabled/token/offline states, parser failures, and duplicate in-flight suppression. | | `src/components/hermes/__tests__/hermes-documents-gallery.test.tsx` | Updated admin hook fixture shape for the new `moa` action group. | | `src/components/hermes/__tests__/hermes-mission-control.test.tsx` | Updated admin hook fixture shape for the new `moa` action group. | | `src/components/hermes/__tests__/hermes-sections.test.tsx` | Updated admin hook fixture shape for the new `moa` action group. | | `src/components/hermes/chat/__tests__/hermes-chat-tab.test.tsx` | Updated admin hook fixture shape for the new `moa` action group. | | `src/components/hermes/intelligence/__tests__/intelligence-portal.test.tsx` | Updated admin hook fixture shape for the new `moa` action group. | | `src/components/knowledge-graph/__tests__/knowledge-graph-grounded-chat.test.tsx` | Updated admin hook fixture shape for the new `moa` action group. | *** ## Technical Decisions 1. **Endpoint-only scope**: Added the write contract and hook action without exposing Ministry builder UI, because Sessions 14 and 15 own the visible product surface. 2. **Validate before filesystem access**: Rejected malformed and unknown MoA fields before reading or writing `config.yaml`, keeping the local control-plane boundary narrow. 3. **Narrow YAML mutation**: Merged only `moa.presets[name]` and `moa.default_preset`, preserving unrelated config keys and existing presets. 4. **Browser-safe responses**: Returned only preset/default/backup labels and controlled setup or write errors with no raw paths, YAML contents, account data, tokens, or secret-shaped strings. *** ## Test Results | Metric | Value | | -------------- | ---------------------------------------------------------------- | | Focused Tests | 101 | | Focused Passed | 101 | | Full Tests | 4708 | | Full Passed | 4708 | | Coverage | Not collected; no coverage command was required by this session. | *** ## Lessons Learned 1. The existing command endpoint patterns are reusable for additional admin-gated Hermes writes when the route keeps validation and safe errors at the bridge boundary. 2. Updating admin hook result shape affects fixture-heavy tests even when no visible UI behavior changes. 3. Targeted formatting can be required for current session artifacts while unrelated historical `.spec_system` Markdown remains outside scope. *** ## Future Considerations Items for future sessions: 1. Session 14 can wire Ministry builder output to the typed MoA save request. 2. Session 15 can add save UX and analytics on top of the existing admin-gated save action. 3. Connection and catalog sessions should continue using parser-owned contracts and no-leak bridge tests for browser-visible data. *** ## Session Statistics * **Tasks**: 20 completed * **Files Created**: 0 production files; 1 updateprd summary file * **Files Modified**: 12 production/test files plus workflow tracking files * **Tests Added**: 10 focused tests * **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://ai-os-and-trend-finder.gitbook.io/ai-os-and-trend-finder-docs/.spec_system/archive/sessions/phase40-session06-moa-save-endpoint/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.
