The session added parity evidence, expanded bridge, hook, and portal test coverage, verified the shipped behavior with focused and full validation gates, and queued exact Session 17 documentation notes. *** ## Deliverables ### Files Created | File | Purpose | Lines | | ------------------------------------------------------------------------------------------------ | -------------------------------------------------------------- | ----- | | `.spec_system/specs/phase40-session16-voice-parity-and-broker-respawn/spec.md` | Session scope, objectives, deliverables, and success criteria. | \~331 | | `.spec_system/specs/phase40-session16-voice-parity-and-broker-respawn/tasks.md` | Completed 20-task implementation checklist. | \~66 | | `.spec_system/specs/phase40-session16-voice-parity-and-broker-respawn/implementation-notes.md` | Voice parity audit, task log, evidence, and docs queue. | \~731 | | `.spec_system/specs/phase40-session16-voice-parity-and-broker-respawn/code-review.md` | Review result and resolved findings. | \~71 | | `.spec_system/specs/phase40-session16-voice-parity-and-broker-respawn/security-compliance.md` | Security and GDPR review for the session. | \~80 | | `.spec_system/specs/phase40-session16-voice-parity-and-broker-respawn/validation.md` | Final validation report with PASS result. | \~215 | | `.spec_system/specs/phase40-session16-voice-parity-and-broker-respawn/IMPLEMENTATION_SUMMARY.md` | Completion summary for updateprd handoff. | \~70 | ### Files Modified | File | Changes | | --------------------------------------------------------------------------- | ----------------------------------------------------------------------------------------- | | `.spec_system/state.json` | Marked the session complete, cleared `current_session`, and appended completion history. | | `.spec_system/PRD/phase_40/PRD_phase_40.md` | Updated progress to 16/18, marked Session 16 complete, and added completed-session notes. | | `package.json` | Incremented patch version from `0.5.119` to `0.5.120`. | | `README.md` | Synced the root version line to `0.5.120`. | | `docs/CHANGELOG.md` | Added the Phase 40 Session 16 release entry. | | `scripts/lib/__tests__/voice-launch-bridge.test.ts` | Added empty launch, payload rejection, env-only spawn, and base-policy coverage. | | `src/hooks/__tests__/use-hermes-intelligence-voice.test.tsx` | Added payload shape, launch ordering, error mapping, and cleanup coverage. | | `src/components/hermes/intelligence/__tests__/intelligence-portal.test.tsx` | Added product control and recovery-copy coverage. | *** ## Technical Decisions 1. **Preserve environment-backed voice credentials**: AI OS intentionally does not port browser localStorage OpenAI key persistence because voice provider credentials remain local environment inputs. 2. **Treat no-reprompt parity as broker respawn**: The product outcome is achieved when a down broker can restart from ignored local env without asking the user for a browser-supplied provider key. 3. **Use tests as the parity proof**: Production code required no changes; the session locked the behavior with focused bridge, hook, and portal tests. *** ## Test Results | Metric | Value | | ------------------ | ------------- | | Focused test files | 6 passed | | Focused tests | 73 passed | | Full test files | 420 passed | | Full tests | 4816 passed | | Coverage | Not generated | | Typecheck | PASS | | Script typecheck | PASS | | Lint | PASS | *** ## Lessons Learned 1. Voice parity should be described as preserving the user outcome, not copying the upstream credential storage mechanism. 2. The browser-to-local bridge boundary needs explicit negative tests for every provider-config shape that could accidentally leak secrets. 3. Documentation should wait for implementation evidence and keep live-provider claims clearly caveated when validation uses mocked broker/provider runs. *** ## Future Considerations Items for future sessions: 1. Session 17 should update docs with the queued voice behavior notes and Session 08/Session 09 ownership caveats. 2. Session 17 should keep public/demo docs clear that live voice is local-admin only and unavailable in hosted demo mode. 3. Session 18 should rerun the full validation and handoff gates after docs and metadata closeout. *** ## Session Statistics * **Tasks**: 20 completed * **Files Created**: 7 * **Files Modified**: 8 * **Tests Added**: 9 * **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-session16-voice-parity-and-broker-respawn/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.
