The renderer now reuses a latest-value render projection when the run snapshot and render inputs are unchanged, while animation and Pixi presentation work continue every frame. Maintained docs now describe current Web Audio mixing, local Ogg assets, browser-local state, and the reviewed 900 KB music cap without claiming unimplemented ducking. *** ## Deliverables ### Files Created | File | Purpose | Lines | | -------------------------------------------------------------------------------------------------- | ------------------------------------- | ----- | | `.spec_system/specs/phase34-session07-render-performance-and-audio-docs/spec.md` | Session scope and acceptance contract | 373 | | `.spec_system/specs/phase34-session07-render-performance-and-audio-docs/tasks.md` | Completed 20-task checklist | 76 | | `.spec_system/specs/phase34-session07-render-performance-and-audio-docs/implementation-notes.md` | Task-by-task implementation evidence | 716 | | `.spec_system/specs/phase34-session07-render-performance-and-audio-docs/code-review.md` | Review gate report | 119 | | `.spec_system/specs/phase34-session07-render-performance-and-audio-docs/security-compliance.md` | Security and GDPR assessment | 94 | | `.spec_system/specs/phase34-session07-render-performance-and-audio-docs/validation.md` | Validation report | 212 | | `.spec_system/specs/phase34-session07-render-performance-and-audio-docs/IMPLEMENTATION_SUMMARY.md` | Update PRD closeout summary | \~100 | ### Files Modified | File | Changes | | ---------------------------------------------------------------------- | ---------------------------------------------------------------------------------------- | | `.spec_system/state.json` | Marked Session 07 complete, cleared current session, and appended completion history. | | `.spec_system/PRD/phase_34/PRD_phase_34.md` | Updated progress to 7/8, marked Session 07 complete, and added closeout notes. | | `package.json` | Incremented patch version from 0.5.38 to 0.5.39. | | `README.md` | Synced visible version to 0.5.39. | | `docs/CHANGELOG.md` | Added Phase 34 Session 07 closeout notes. | | `src/extensions/ai-rogue/runtime/render-model.ts` | Added the latest-value render projection cache helper and key comparison. | | `src/extensions/ai-rogue/runtime/renderer.ts` | Integrated cached projection reuse and explicit lifecycle invalidation. | | `src/extensions/ai-rogue/runtime/__tests__/render-model.test.ts` | Covered cache reuse, invalidation, seed metadata, preferences, and deterministic output. | | `src/extensions/ai-rogue/runtime/__tests__/renderer-lifecycle.test.ts` | Covered bounded repeated projection builds and lifecycle cache clears. | | `src/extensions/ai-rogue/runtime/audio.ts` | Updated comments to describe implemented audio behavior without ducking claims. | | `docs/extensions/ai-rogue/README.md` | Updated current audio/media and explicit opt-in posture. | | `docs/extensions/ai-rogue/enablement-decision.md` | Labeled no-audio and 200 KB evidence as historical or superseded. | | `docs/extensions/ai-rogue/implementation-baseline.md` | Clarified current image, audio, localStorage, and IndexedDB contracts. | | `docs/extensions/ai-rogue/visual-assets.md` | Distinguished image caps from current audio policy references. | | `.spec_system/PRD/phase_35/PRD_phase_35.md` | Recorded AR-D4-002, AR-D9-001, and AR-D9-002 remediation evidence. | *** ## Technical Decisions 1. **Renderer-local latest cache**: The projection cache is per mounted renderer, not process-wide, so stale game state cannot leak across mounts. 2. **Semantic invalidation key**: Cache reuse requires the same snapshot object plus matching turn, depth, status, viewport, tile scale, HUD, preference, and seed metadata values. 3. **Presentation outside projection**: Background drift, vignette, entity tweens, effects, inspect overlay, camera snap, and `app.render()` stay on the per-frame path. 4. **Document reality before adding audio behavior**: Current docs remove ducking claims rather than adding new audio processing outside this scope. *** ## Test Results | Metric | Value | | --------------------- | ------------------------ | | Focused Runtime Tests | 24 passed / 24 total | | AI Rogue Tests | 307 passed / 307 total | | Full Test Suite | 4338 passed / 4338 total | | Typecheck | PASS | | Lint | PASS | | Format Check | PASS | | Bundle Budget | PASS | | Asset Size Check | PASS | | Private Runtime Check | PASS | *** ## Lessons Learned 1. Hot-loop renderer optimization should stay at the projection boundary so pure model construction can remain deterministic and testable. 2. Historical enablement evidence needs explicit labels when later sessions change media capabilities or size policies. *** ## Future Considerations Items for future sessions: 1. Session 08 should include the resolved AR-D4 and AR-D9 evidence in the final AI Rogue default-enablement recommendation. 2. Future audio work should add explicit tests and docs before describing sidechain, compressor, or event-based ducking behavior as implemented. *** ## Session Statistics * **Tasks**: 20 completed * **Files Created**: 7 * **Files Modified**: 15 * **Tests Added**: Focused render-model cache and renderer lifecycle coverage * **Blockers**: 3 audit findings addressed --- # 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/phase34-session07-render-performance-and-audio-docs/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.
