It added five committed Ogg Opus ambience loops, repeatable local generation, provenance, documentation, unit coverage, and desktop/mobile browser proof that all five real runtime assets are fetched and started through the Web Audio path. *** ## Deliverables ### Files Created | File | Purpose | Lines | | -------------------------------------------------------------------------------------- | ----------------------------------------------------------------- | ------ | | `scripts/generate-ai-rogue-theme-ambience.ts` | Local ffmpeg/ffprobe generator for all five theme ambience loops. | 364 | | `src/assets/ai-rogue/audio/music/theme_cold_cache_ambience.ogg` | Cold Cache ambience loop. | binary | | `src/assets/ai-rogue/audio/music/theme_corrupted_index_ambience.ogg` | Corrupted Index ambience loop. | binary | | `src/assets/ai-rogue/audio/music/theme_firewall_ambience.ogg` | Firewall ambience loop. | binary | | `src/assets/ai-rogue/audio/music/theme_kernel_core_ambience.ogg` | Kernel Core ambience loop. | binary | | `src/assets/ai-rogue/audio/music/theme_model_vault_ambience.ogg` | Model Vault ambience loop. | binary | | `.spec_system/specs/phase36-session05-sector-theme-audio-pack/spec.md` | Session specification. | 347 | | `.spec_system/specs/phase36-session05-sector-theme-audio-pack/tasks.md` | Completed 20-task checklist. | 76 | | `.spec_system/specs/phase36-session05-sector-theme-audio-pack/implementation-notes.md` | Implementation evidence ledger. | 808 | | `.spec_system/specs/phase36-session05-sector-theme-audio-pack/code-review.md` | Code review and repair report. | 97 | | `.spec_system/specs/phase36-session05-sector-theme-audio-pack/security-compliance.md` | Security and GDPR review report. | 85 | | `.spec_system/specs/phase36-session05-sector-theme-audio-pack/validation.md` | Validation report. | 272 | ### Files Modified | File | Changes | | ----------------------------------------------------------------- | --------------------------------------------------------------------------------------------------- | | `src/assets/ai-rogue/audio/music/provenance.json` | Added five theme ambience source, render, format, duration, and byte records. | | `tests/e2e/ai-rogue-runtime.spec.ts` | Extended browser proof to cover all five real committed theme ambience files without URL overrides. | | `src/extensions/ai-rogue/runtime/__tests__/audio.test.ts` | Added coverage for the theme ambience asset count/contract. | | `docs/extensions/ai-rogue/game-feel.md` | Updated game-feel docs from reserved contract to shipped ambience pack and review evidence. | | `tsconfig.scripts.json` | Included DOM libs for script typechecking through runtime audio imports. | | `.spec_system/PRD/phase_36/session_05_sector_theme_audio_pack.md` | Recorded implementation evidence and completion. | | `.spec_system/PRD/phase_36/PRD_phase_36.md` | Marked session 05 complete and updated phase progress. | | `.spec_system/state.json` | Marked current session complete and cleared `current_session`. | | `package.json` | Bumped patch version from `0.5.60` to `0.5.61`. | | `README.md` | Synced displayed project version to `0.5.61`. | *** ## Technical Decisions 1. **Commit local optimized ambience loops**: Runtime assets are local Ogg Opus files under the existing music asset policy, keeping public-demo safety and no remote game-content loading intact. 2. **Use a repeatable local generator**: The generation script uses local ffmpeg/ffprobe and gitignored scratch masters, avoiding credentials, network APIs, and unreviewed raw media commits. 3. **Preserve the Session 04 audio contract**: The asset pack uses the existing low-gain ambience lane keyed by `snapshot.theme` and inherits existing mute, music volume, autoplay unlock, and silent fallback behavior. *** ## Test Results | Metric | Value | | -------- | ------------ | | Tests | 4395 | | Passed | 4395 | | Coverage | Not reported | Additional validation passed: `bun run lint`, `bun run typecheck`, `bun run typecheck:scripts`, targeted Prettier check, `bash scripts/check-asset-sizes.sh`, ffprobe verification for all five loops, provenance checks, ASCII/LF scans, and focused Playwright browser audio proof. *** ## Lessons Learned 1. The Session 04 route contract let the asset pack ship without changing runtime audio architecture. 2. Browser proof should use real committed Vite asset URLs for media contract tests; injected test URLs can hide basename or asset-glob drift. 3. Script typechecking needs the DOM lib when script graphs import browser audio modules. *** ## Future Considerations Items for future sessions: 1. Session 06 can build adaptive music behavior on top of the shipped ambience lane. 2. Session 07 should only add stingers if the engine contract defines clear ducking and transient gain behavior. 3. Session 08 should include human acoustic listening in addition to browser path proof. *** ## Session Statistics * **Tasks**: 20 completed * **Files Created**: 12 * **Files Modified**: 10 * **Tests Added**: Focused unit coverage and 2 browser proof cases updated * **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/phase36-session05-sector-theme-audio-pack/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.
