Sensitive reads and writes still fail closed when same-run token bootstrap fails, while normal local write readiness now derives from parsed `writeReady` status instead of manual admin opt-in. *** ## Deliverables ### Files Created | File | Purpose | Lines | | --------------------------------------------------------------------------------------------- | ------------------------------ | ----- | | `.spec_system/specs/phase41-session03-hermes-route-modes-and-hooks/spec.md` | Session specification | 258 | | `.spec_system/specs/phase41-session03-hermes-route-modes-and-hooks/tasks.md` | Completed task checklist | 65 | | `.spec_system/specs/phase41-session03-hermes-route-modes-and-hooks/implementation-notes.md` | Implementation evidence ledger | 616 | | `.spec_system/specs/phase41-session03-hermes-route-modes-and-hooks/code-review.md` | Code review and repair report | 107 | | `.spec_system/specs/phase41-session03-hermes-route-modes-and-hooks/security-compliance.md` | Security and GDPR review | 92 | | `.spec_system/specs/phase41-session03-hermes-route-modes-and-hooks/validation.md` | Validation report | 209 | | `.spec_system/specs/phase41-session03-hermes-route-modes-and-hooks/IMPLEMENTATION_SUMMARY.md` | Session closeout summary | 96 | ### Files Modified | File | Changes | | --------------------------------------------------------------------------------- | ------------------------------------------------------------------------------------------------------------------------------ | | `src/lib/hermes-types.ts` | Replaced ready `read-only` route mode with `live-local` and added route-mode helper coverage points. | | `src/hooks/use-hermes.ts` | Delegated route-mode calculation, preserved token-gated sensitive reads, and updated demo fallback eligibility. | | `src/hooks/use-hermes-admin.ts` | Based admin write capability on parsed `writeReady` plus automatic token readiness while preserving duplicate mutation guards. | | `src/components/hermes/hermes-cli-cheatsheet.tsx` | Treated `live-local` as the ready Hermes terminal state. | | `src/components/hermes/hermes-status-bar.tsx` | Removed legacy read-only bridge wording from local support copy. | | `src/lib/__tests__/hermes-types.test.ts` | Added route-mode helper tests for live local, demo, setup, offline, endpoint, and token-failure mapping. | | `src/hooks/__tests__/use-hermes.test.tsx` | Updated ready local expectations and token success/failure coverage. | | `src/hooks/__tests__/use-hermes-admin.test.tsx` | Added writeReady capability, blocker, token, offline, status failure, and duplicate-trigger coverage. | | `src/lib/__tests__/hermes-admin-types.test.ts` | Asserted `adminEnabled` remains a compatibility mirror for `writeReady`. | | `src/routes/__tests__/agents.test.tsx` | Updated ready Hermes route test naming for live local readiness. | | `src/components/hermes/__tests__/hermes-sections.test.tsx` | Updated typed Hermes route-mode fixtures to `live-local`. | | `src/components/home/__tests__/knowledge-graph-section.test.tsx` | Updated typed Hermes route-mode fixture to `live-local`. | | `src/components/knowledge-graph/__tests__/knowledge-graph-grounded-chat.test.tsx` | Updated typed Hermes route-mode fixture to `live-local`. | | `src/components/knowledge-graph/__tests__/knowledge-graph-ingest-card.test.tsx` | Updated typed Hermes route-mode fixture to `live-local`. | | `src/components/knowledge-graph/__tests__/knowledge-graph-page.test.tsx` | Updated typed Hermes route-mode fixture to `live-local`. | | `.spec_system/state.json` | Marked Session 03 complete and cleared `current_session`. | | `.spec_system/PRD/phase_41/PRD_phase_41.md` | Advanced Phase 41 progress to 3/17 sessions. | | `package.json` | Bumped project patch version from 0.5.130 to 0.5.131. | *** ## Technical Decisions 1. **Centralized route-mode mapping**: `getHermesRouteMode()` lives in `src/lib/hermes-types.ts` so ready, demo, setup, offline, endpoint, and token failure decisions are tested once and consumed by hooks. 2. **Compatibility alias retained**: `adminEnabled` remains available for current consumers, but normal local readiness decisions now use `writeReady`. 3. **Token failure remains fail-closed**: Sensitive reads and admin writes require same-run token readiness; token failure stays visible as a blocker instead of falling through to ready local behavior. *** ## Test Results | Metric | Value | | -------- | ------------------------------------------- | | Tests | 4,837 full suite; 110 focused session suite | | Passed | 4,837 full suite; 110 focused session suite | | Coverage | N/A - `bun run test` does not emit coverage | Additional gates passed: `bun run typecheck`, `bun run typecheck:scripts`, `bun run lint`, `bun run format:check`, and `git diff --check 139ad798dfa94839bf20d712fe020aa86b1c793c`. *** ## Lessons Learned 1. Ready route-mode names propagate into typed test fixtures outside the immediate Hermes route, so typecheck is necessary after changing the route contract. 2. `adminEnabled` can stay as a migration alias only if parser and hook tests prove `writeReady` remains the source of capability truth. *** ## Future Considerations Items for future sessions: 1. Session 04 should build on the `live-local` contract when enabling Knowledge Graph writes. 2. Session 07 still owns broad Hermes shell identity and read-only component naming. 3. Session 08 still owns mutation-control copy and UX across Hermes action surfaces. *** ## Session Statistics * **Tasks**: 19 completed * **Files Created**: 7 * **Files Modified**: 18 * **Tests Added**: 12 * **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/specs/phase41-session03-hermes-route-modes-and-hooks/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.
