The work created an evidence-backed audit of upstream changes, mapped AI OS Hermes ownership boundaries, recorded non-negotiable port invariants, classified upstream deltas, and validated that no production source, public docs behavior, package behavior, graph data, assets, or user-facing UI changed during the baseline session. *** ## Deliverables ### Files Created | File | Purpose | Lines | | ------------------------------------------------------------------------------------------- | ---------------------------------------------------------------------------------------------- | ----- | | `.spec_system/specs/phase40-session01-baseline-and-port-invariants/spec.md` | Session scope, objectives, requirements, and acceptance criteria. | \~296 | | `.spec_system/specs/phase40-session01-baseline-and-port-invariants/tasks.md` | Completed 20-task implementation checklist and evidence routing. | \~77 | | `.spec_system/specs/phase40-session01-baseline-and-port-invariants/implementation-notes.md` | Baseline audit notes, invariant list, decision list, owner mapping, and classification ledger. | \~939 | | `.spec_system/specs/phase40-session01-baseline-and-port-invariants/code-review.md` | Review and repair report for all changes since the session base commit. | \~75 | | `.spec_system/specs/phase40-session01-baseline-and-port-invariants/security-compliance.md` | Security and GDPR review for the session artifact surface. | \~76 | | `.spec_system/specs/phase40-session01-baseline-and-port-invariants/validation.md` | Validation report showing overall PASS and command evidence. | \~213 | ### Files Modified | File | Changes | | ------------------------------------------- | ----------------------------------------------------------------------------------- | | `.spec_system/state.json` | Marked Session 01 validated and completed, then cleared the active current session. | | `.spec_system/PRD/phase_40/PRD_phase_40.md` | Updated Phase 40 progress to 1/18 sessions and marked Session 01 complete. | | `.spec_system/PRD/PRD.md` | Marked Phase 40 as in progress in the master phase table. | | `package.json` | Incremented project patch version from `0.5.103` to `0.5.104`. | | `README.md` | Updated the visible project version from `0.5.103` to `0.5.104`. | *** ## Technical Decisions 1. **Semantic port only**: Upstream monolithic route and Vite middleware code must be translated into existing AI OS Hermes owners rather than copied. 2. **Sanitized diagnostics**: Chat SSE stderr diagnostics should surface as sanitized `info` events, not assistant reply text. 3. **Demo-safe live data**: Live pricing and provider checks stay local, source-labeled, fail-soft, and disabled in public/demo mode. 4. **Environment-only voice credentials**: Browser voice-key persistence is an intentional non-port; AI OS keeps provider credentials environment-backed. *** ## Test Results | Metric | Value | | --------------------------------- | ---------------------------------------------------------------------------------------- | | Full test suite | PASS - 409 files, 4662 tests | | Focused Hermes tests | PASS - 5 files, 190 tests | | Focused voice/control-plane tests | PASS - 7 files, 63 tests | | Typecheck | PASS - `bun run typecheck` | | Script typecheck | PASS - `bun run typecheck:scripts` | | Lint | PASS - `bun run lint` | | Markdown/format/whitespace | PASS - targeted Markdown lint, targeted Prettier, ASCII/LF scans, and `git diff --check` | | Coverage | Not reported by the validation run | *** ## Lessons Learned 1. Baseline sessions are useful when upstream ports are broad: stable invariant IDs prevent later feature sessions from reopening architecture boundaries. 2. Privacy scans must include generated spec artifacts because raw upstream or plugin paths can leak through evidence records. 3. The Phase 40 port should preserve existing AI OS split ownership and treat upstream behavior as requirements, not source to copy. *** ## Future Considerations Items for future sessions: 1. Session 02 should use the owner mapping and classification ledger before changing model/provider readiness behavior. 2. Sessions that add bridge writes must preserve loopback, Host-header, same-run token, admin, method, body-size, schema, timeout, and safe-error gates. 3. Session 10 should avoid importing upstream `ministry-hero.webp` as-is because it exceeds the current non-logo asset cap. *** ## Session Statistics * **Tasks**: 20 completed * **Files Created**: 6 * **Files Modified**: 5 * **Tests Added**: 0 * **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-session01-baseline-and-port-invariants/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.
