Enemy templates now declare audio families and frame sets, audio cue routing reads that metadata with safe fallbacks, and content validation derives gameplay frame requirements from authored contracts. The session also added deterministic audio URL, provenance, atlas, malformed content, and behavior-preservation coverage. *** ## Deliverables ### Files Created | File | Purpose | Lines | | -------------------------------------------------------------------------------------------------------- | ------------------------ | ----- | | `.spec_system/specs/phase39-session05-enemy-metadata-and-derived-asset-checks/spec.md` | Session specification | 359 | | `.spec_system/specs/phase39-session05-enemy-metadata-and-derived-asset-checks/tasks.md` | Task checklist | 73 | | `.spec_system/specs/phase39-session05-enemy-metadata-and-derived-asset-checks/implementation-notes.md` | Implementation evidence | 647 | | `.spec_system/specs/phase39-session05-enemy-metadata-and-derived-asset-checks/code-review.md` | Review and repair report | 115 | | `.spec_system/specs/phase39-session05-enemy-metadata-and-derived-asset-checks/security-compliance.md` | Security and GDPR report | 99 | | `.spec_system/specs/phase39-session05-enemy-metadata-and-derived-asset-checks/validation.md` | Validation report | 214 | | `.spec_system/specs/phase39-session05-enemy-metadata-and-derived-asset-checks/IMPLEMENTATION_SUMMARY.md` | Session closeout summary | \~90 | ### Files Modified | File | Changes | | ------------------------------------------------------------------ | ------------------------------------------------------------------------------------------------- | | `src/extensions/ai-rogue/runtime/types-entities.ts` | Added enemy audio-family, standard frame-set, boss frame-set, and template metadata contracts. | | `src/extensions/ai-rogue/runtime/entities.ts` | Added metadata to enemy templates, safe lookup helpers, and explicit runtime enemy projection. | | `src/extensions/ai-rogue/runtime/audio.ts` | Replaced enemy-family switch routing with metadata lookup and added audio asset manifest helpers. | | `src/extensions/ai-rogue/runtime/content/types.ts` | Added derived frame requirement result types and issue code support. | | `src/extensions/ai-rogue/runtime/content/validate.ts` | Added derived gameplay frame requirements and stable validation issue mapping. | | `src/extensions/ai-rogue/runtime/content/index.ts` | Exported derived validation helpers. | | `src/extensions/ai-rogue/runtime/assets.ts` | Split static and derived gameplay frame requirements while preserving atlas validation. | | `src/extensions/ai-rogue/runtime/__tests__/ecology.test.ts` | Added metadata completeness, lookup, atlas, and projection coverage. | | `src/extensions/ai-rogue/runtime/__tests__/audio.test.ts` | Added metadata routing, asset URL, and provenance coverage. | | `src/extensions/ai-rogue/runtime/__tests__/assets.test.ts` | Added derived frame, static boundary, and missing-frame tests. | | `src/extensions/ai-rogue/runtime/content/__tests__/levels.test.ts` | Added derived validation and safe malformed-content coverage. | | `docs/ongoing-projects/ai-rogue-phase-39-asset-generation-plan.md` | Corrected current contract wording for soundtrack fields and shipped fourth-floor examples. | | `.spec_system/state.json` | Marked Session 05 complete and cleared current session. | | `.spec_system/PRD/phase_39/PRD_phase_39.md` | Updated Phase 39 progress to 5/8 sessions. | | `README.md` | Updated version line to `0.5.94`. | | `docs/CHANGELOG.md` | Added Session 05 release notes. | | `package.json` | Bumped package version to `0.5.94`. | *** ## Technical Decisions 1. **Catalog-owned metadata**: Enemy metadata lives in `AI_ROGUE_ENEMY_TEMPLATES` so the existing catalog remains the source of truth. 2. **Runtime projection boundary**: `createAiRogueEnemy()` explicitly projects runtime state fields so metadata cannot leak into saves. 3. **Derived validation before runtime**: Content validation now derives frame and audio coverage from typed source contracts so missing assets fail in tests. 4. **Behavior-preserving audio migration**: Audio routing moved from switches to metadata while retaining generic, sentry, and boss fallback behavior. *** ## Test Results | Metric | Value | | ---------- | ----- | | Tests | 4649 | | Passed | 4649 | | Coverage | N/A | | Typecheck | PASS | | Lint | PASS | | Asset size | PASS | *** ## Lessons Learned 1. Source metadata must stay outside persisted enemy state; explicit projection is the safest local pattern. 2. Derived asset checks are useful only when malformed-reference messages stay deterministic and privacy-safe. 3. Audio provenance can be validated through narrow manifest helpers without changing lazy decode behavior. *** ## Future Considerations Items for future sessions: 1. Session 06 should reuse the Kernel Sentinel frame metadata when generalizing boss and finale contracts. 2. Session 07 should add real content through catalog and level-spec paths so these derived checks prove their authoring value. 3. Session 08 should document the final validation workflow once boss, finale, and real-content paths settle. *** ## Session Statistics * **Tasks**: 18 completed * **Files Created**: 7 * **Files Modified**: 17 * **Tests Added**: Focused metadata, audio manifest, provenance, derived asset, and content validation 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/phase39-session05-enemy-metadata-and-derived-asset-checks/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.
