The session added reviewed Cold Cache, Corrupted Index, Firewall, Model Vault, and Kernel Core tile/decal crops, regenerated the gameplay atlas, added typed theme visual contracts, wired deterministic theme tile variants, sparse decals, and atmosphere rendering, and proved the result through focused tests, full Vitest, and desktop/mobile browser coverage. *** ## Deliverables ### Files Created | File | Purpose | Lines | | -------------------------------------------------------------------------------- | ---------------------------------------------------- | ------ | | `.spec_system/specs/phase37-session04-g3-theme-decals/spec.md` | Session specification | \~377 | | `.spec_system/specs/phase37-session04-g3-theme-decals/tasks.md` | Task checklist and completion tracker | \~158 | | `.spec_system/specs/phase37-session04-g3-theme-decals/implementation-notes.md` | Implementation ledger and evidence | \~1081 | | `.spec_system/specs/phase37-session04-g3-theme-decals/code-review.md` | Code review and repair report | \~134 | | `.spec_system/specs/phase37-session04-g3-theme-decals/security-compliance.md` | Security and GDPR review | \~100 | | `.spec_system/specs/phase37-session04-g3-theme-decals/validation.md` | Validation report | \~224 | | `.spec_system/specs/phase37-session04-g3-theme-decals/IMPLEMENTATION_SUMMARY.md` | Session closeout summary | \~86 | | `src/extensions/ai-rogue/runtime/theme-visuals.ts` | Typed theme visual mapping and deterministic helpers | \~255 | | `src/extensions/ai-rogue/runtime/__tests__/theme-visuals.test.ts` | Theme visual helper coverage | \~199 | ### Files Modified | File | Changes | | --------------------------------------------------------------------------------- | ----------------------------------------------------------------------------------------- | | `.spec_system/state.json` | Marked Session 04 complete, cleared current session, and appended completion history. | | `.spec_system/PRD/phase_37/PRD_phase_37.md` | Updated Phase 37 progress to 4/6 sessions and advanced the next step to G6 UI Cinematics. | | `.spec_system/PRD/phase_37/session_04_g3_theme_decals.md` | Marked Session 04 complete and checked prerequisites/success criteria. | | `package.json` | Bumped project version from 0.5.67 to 0.5.68. | | `README.md` | Synced displayed project version to 0.5.68. | | `docs/ongoing-projects/generated/ai-rogue-visual-audio-assets/crop-manifest.json` | Added accepted and rejected G3 crop decisions. | | `src/assets/ai-rogue/gameplay-atlas.png` | Regenerated gameplay atlas with G3 frames. | | `src/assets/ai-rogue/gameplay-atlas.json` | Regenerated gameplay atlas metadata and G3 frame keys. | | `docs/extensions/ai-rogue/generated/ai-rogue-production-atlas-preview.png` | Regenerated docs preview. | | `src/extensions/ai-rogue/runtime/types-assets.ts` | Added typed G3 tile/decal frame contracts. | | `src/extensions/ai-rogue/runtime/assets.ts` | Added required gameplay frame validation for G3 frames. | | `src/extensions/ai-rogue/runtime/themes.ts` | Connected sector theme metadata to visual mapping. | | `src/extensions/ai-rogue/runtime/world-generator.ts` | Added rule-preserving theme frame selection. | | `src/extensions/ai-rogue/runtime/render-model.ts` | Added sparse deterministic theme decal projection. | | `src/extensions/ai-rogue/runtime/renderer-layers.ts` | Added theme-aware atmosphere colors. | | `src/extensions/ai-rogue/runtime/renderer.ts` | Passed the active theme into background rendering. | | `src/extensions/ai-rogue/runtime/__tests__/assets.test.ts` | Covered G3 frame requirements and atlas counts. | | `src/extensions/ai-rogue/runtime/__tests__/themes.test.ts` | Covered sector theme visual metadata. | | `src/extensions/ai-rogue/runtime/__tests__/world.test.ts` | Proved seeded world rules stay stable while frame names vary. | | `src/extensions/ai-rogue/runtime/__tests__/render-model.test.ts` | Covered decals, ordering, labels, high contrast, and reduced motion. | | `src/extensions/ai-rogue/runtime/__tests__/biome-final.test.ts` | Preserved theme pressure and final-depth behavior. | | `tests/e2e/ai-rogue-runtime.spec.ts` | Added desktop browser proof for distinct G3 theme visuals. | | `tests/e2e/ai-rogue-mobile.spec.ts` | Added mobile browser proof for readable G3 theme decals. | | `docs/extensions/ai-rogue/visual-assets.md` | Documented G3 atlas counts, decisions, evidence, and caveats. | *** ## Technical Decisions 1. **Manifest-first asset acceptance**: G3 crops are reviewed in the manifest before atlas generation, with explicit rejected entries for text-like, stripe-like, lock, target, and diagnostic-risk candidates. 2. **Typed theme visual helper**: `theme-visuals.ts` centralizes tile variants, sparse decal choices, atmosphere colors, deterministic placement, and fallback behavior. 3. **Presentation-only world changes**: World generation only changes frame names for equivalent tiles; topology, passability, sight blocking, hazard damage, enemy placement, pickups, objectives, and saves remain unchanged. 4. **Canonical special frames preserved**: The code review repair kept door, vault, terminal, exit, and relic-shrine base frames intact while allowing theme identity through ordinary floor, wall, hazard, decals, and atmosphere. *** ## Test Results | Metric | Value | | ------------------ | ----------------------------------------- | | Asset packer | PASS - gameplay 234 frames, UI 115 frames | | Typecheck | PASS | | Script typecheck | PASS | | Lint | PASS | | Asset-size check | PASS - total 15M | | Focused Vitest | PASS - 61/61 tests | | Full Vitest | PASS - 4,443/4,443 tests | | Desktop Playwright | PASS - 1/1 Chromium test | | Mobile Playwright | PASS - 1/1 Chromium test | | Coverage | Not generated | *** ## Lessons Learned 1. Theme tile replacement must preserve canonical interactable frames or player affordances regress even when the visuals look more thematic. 2. Recording rejected generated-art candidates is useful because no-text-safe decisions are as important as accepted crops for future atlas work. 3. Browser proofs are necessary for visual sessions because frame contracts and atlas metadata alone do not prove the product-facing outcome. *** ## Future Considerations Items for future sessions: 1. Continue Phase 37 with Session 05, G6 UI Cinematics. 2. Finish Phase 37 with Session 06, G7 Player Animation. 3. Track full-repo Prettier cleanup for unchanged historical markdown reports separately; touched-file formatting passed for this session. *** ## Session Statistics * **Tasks**: 22 completed * **Files Created**: 9 * **Files Modified**: 24 * **Tests Added**: 1 new focused test file plus expanded existing unit and e2e 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/phase37-session04-g3-theme-decals/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.
