The home cockpit now gets a dedicated Knowledge Graph section with lazy 3D preview loading, seed/live summary data, bounded copy, and a route link into `/knowledge-graph`. The Shared Brain setup script is idempotent, resolves or installs `graphify`, registers the Hermes and Claude Code graphify skills, prepends the shared-brain note once, and backfills registry paths safely. The dashboard ingest helper reads the local token, posts to `/__graphify_ingest`, and keeps token material out of stdout. Hermes bridge and scanner readiness logic now treat OAuth-backed providers separately from API-key providers so missing `~/.hermes/.env` keys do not create false setup-needed states. *** ## Deliverables ### Files Created | File | Purpose | Lines | | ---------------------------------------------------------------- | ------------------------------------------------------------------------------ | ----- | | `src/lib/knowledge-graph-home-summary.ts` | Pure summary projection for home Knowledge Graph stats and provenance | \~303 | | `src/lib/__tests__/knowledge-graph-home-summary.test.ts` | Summary helper coverage for fallback and bounded display behavior | \~170 | | `src/components/home/knowledge-graph-section.tsx` | Home Knowledge Graph section with lazy preview and state handling | \~297 | | `src/components/home/__tests__/knowledge-graph-section.test.tsx` | Component coverage for loading, fallback, and navigation states | \~265 | | `scripts/setup-graphify-brain.sh` | Idempotent Shared Brain setup script for graphify, skills, and registry repair | \~225 | | `scripts/graph-to-dashboard.sh` | Local dashboard ingest helper with token read and safe POST behavior | \~162 | | `scripts/lib/__tests__/graphify-shared-brain-scripts.test.ts` | Script smoke coverage for naming, redaction, and JSON encoding | \~64 | ### Files Modified | File | Changes | | ------------------------------------------------- | -------------------------------------------------- | | `src/routes/index.tsx` | Mounted the new home Knowledge Graph section | | `scripts/lib/hermes-dev-bridge.ts` | Added OAuth provider readiness classification | | `scripts/lib/hermes-scanner.ts` | Mirrored OAuth readiness logic for scanner parity | | `scripts/lib/__tests__/hermes-dev-bridge.test.ts` | Added API-key and OAuth regression coverage | | `scripts/lib/__tests__/hermes-scanner.test.ts` | Added scanner regression coverage for OAuth parity | | `.gitignore` | Ignored generated `graphify-out/` output | *** ## Technical Decisions 1. **Keep the home surface thin**: the route only mounts a dedicated section and summary helper so the home page does not accumulate graph-specific logic. 2. **Treat OAuth readiness separately from API keys**: provider status should reflect the real auth model instead of assuming every provider depends on `~/.hermes/.env`. 3. **Make the local scripts idempotent**: repeated setup runs should not duplicate notes, corrupt registry paths, or leak token values. *** ## Test Results | Metric | Value | | -------- | ----- | | Tests | 3305 | | Passed | 3305 | | Coverage | N/A | *** ## Lessons Learned 1. The home Knowledge Graph surface stays more maintainable when summary derivation and rendering are separated. 2. Shell helpers need explicit redaction and bounded failure output when they interact with local tokens. 3. Readiness logic drifts quickly unless the bridge and scanner share the same provider classification rules. *** ## Future Considerations Items for future sessions: 1. Complete phase 26 documentation, validation, and release closeout. 2. Keep the home Knowledge Graph summary aligned with any future registry or seed graph changes. *** ## Session Statistics * **Tasks**: 23 completed * **Files Created**: 7 * **Files Modified**: 6 * **Tests Added**: 5 * **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/phase26-session08-homepage-surface-shared-brain-scripts-oauth/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.
