The implementation expands the browser model parser and public bridge contract so AI OS keeps the existing `ok` and `configuredDefault` compatibility while also accepting upstream-style `default`, `catalog`, `mixtures`, and `configured` model bodies. Provider readiness now handles retained AI OS aliases and upstream aliases, derives safe configured-provider summaries, discovers MoA presets from local Hermes config, and keeps browser output free of raw config, auth, env, token-shaped, and private-path data. *** ## Deliverables ### Files Created | File | Purpose | Lines | | ---------------------------------------------------------------------------------------------- | ----------------------------------- | ----- | | `.spec_system/specs/phase40-session02-models-and-provider-readiness/code-review.md` | Review and repair report | \~101 | | `.spec_system/specs/phase40-session02-models-and-provider-readiness/security-compliance.md` | Security and GDPR compliance report | \~84 | | `.spec_system/specs/phase40-session02-models-and-provider-readiness/validation.md` | Session validation report | \~211 | | `.spec_system/specs/phase40-session02-models-and-provider-readiness/IMPLEMENTATION_SUMMARY.md` | Final updateprd summary | \~80 | ### Files Modified | File | Changes | | --------------------------------------------------------------------- | --------------------------------------------------------------------------------------------------------------------------------------------------------------- | | `src/lib/hermes-types.ts` | Extended model response types and tolerant parser normalization for old AI OS, expanded AI OS, and upstream no-`ok` bodies. | | `src/lib/hermes-demo-data.ts` | Verified safe expanded demo model fixture behavior with no local configured-provider summaries. | | `src/hooks/use-hermes.ts` | Preserved stable hook consumption of the normalized model parser output. | | `scripts/lib/hermes-dev-bridge.ts` | Added safe Hermes config reads, MoA mixture discovery, configured-provider derivation, expanded model body output, deterministic filtering, and no-leak guards. | | `scripts/lib/hermes-provider-readiness.ts` | Added upstream and retained AI OS provider aliases, labels, OAuth/subscription handling, and key-name helpers. | | `scripts/lib/__tests__/hermes-dev-bridge.test.ts` | Added bridge coverage for aliases, configured derivation, MoA discovery, malformed/missing config, and no-leak behavior. | | `src/lib/__tests__/hermes-types.test.ts` | Added parser coverage for compatibility envelopes, context, mixtures, configured providers, and invalid shapes. | | `src/hooks/__tests__/use-hermes.test.tsx` | Updated hook fixtures for expanded model bodies. | | `src/components/hermes/__tests__/hermes-sections.test.tsx` | Updated component test fixtures for expanded model bodies. | | `.spec_system/PRD/phase_40/session_10_assets_and_media_compliance.md` | Redacted a local upstream checkout path noted during review. | | `.spec_system/PRD/phase_40/PRD_phase_40.md` | Marked Session 02 complete and updated phase progress. | | `.spec_system/state.json` | Recorded Session 02 completion and cleared the current session. | | `package.json` | Bumped package version from 0.5.105 to 0.5.106. | | `README.md` | Updated the visible version line to 0.5.106. | *** ## Technical Decisions 1. **Compatibility parser**: Normalize old AI OS, expanded AI OS, and upstream no-`ok` model bodies into one stable browser-facing shape. 2. **Safe local projection**: Expose only provider slugs, display labels, model metadata, preset names, and counts derived from local files. 3. **Alias-first filtering**: Normalize provider aliases before configured filtering so Google/Gemini, xAI, OpenRouter, MiniMax, NVIDIA, DeepSeek, Sakana, and retained AI OS aliases behave predictably. 4. **Fail-soft config reads**: Missing or malformed Hermes config yields an empty safe summary instead of failing the public read endpoint. *** ## Test Results | Metric | Value | | -------------- | ------------- | | Focused Tests | 40 | | Focused Passed | 40 | | Full Tests | 4668 | | Full Passed | 4668 | | Coverage | Not collected | *** ## Lessons Learned 1. Provider filtering must fall back to the full deterministic catalog when configured providers are recognized but no current catalog group matches. 2. `GOOGLE_GENERATIVE_AI_API_KEY` needs to remain a retained AI OS Google Gemini provider alias. 3. MoA mixture `references` can be zero and should be parsed as a non-negative integer. *** ## Future Considerations Items for future sessions: 1. Session 03 should build shared redaction foundations on top of the no-leak behavior proven here. 2. Session 04 should wire chat model/provider overrides against this expanded model contract. 3. Session 08 and Session 09 should refresh catalog metadata, context, pricing, and provenance after the response shape is stable. *** ## Session Statistics * **Tasks**: 18 completed * **Files Created**: 4 * **Files Modified**: 14 * **Tests Added**: Focused parser, bridge, hook, and component fixture 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://ai-os-and-trend-finder.gitbook.io/ai-os-and-trend-finder-docs/.spec_system/archive/sessions/phase40-session02-models-and-provider-readiness/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.
