Kernel Sentinel is now represented through a reusable boss spec, runtime boss and finale decisions route through metadata-backed helpers, and final-defense presentation ownership comes from authored finale metadata instead of a raw depth comparison. *** ## Deliverables ### Files Created | File | Purpose | Lines | | ---------------------------------------------------------------------------------------- | ------------------------------------------------ | ----- | | `src/extensions/ai-rogue/runtime/boss-contracts.ts` | Typed boss and authored-finale contract helpers. | \~246 | | `.spec_system/specs/phase39-session06-boss-and-finale-contracts/spec.md` | Session specification. | \~233 | | `.spec_system/specs/phase39-session06-boss-and-finale-contracts/tasks.md` | Completed task checklist. | \~75 | | `.spec_system/specs/phase39-session06-boss-and-finale-contracts/implementation-notes.md` | Implementation evidence log. | \~783 | | `.spec_system/specs/phase39-session06-boss-and-finale-contracts/code-review.md` | Review and repair report. | \~83 | | `.spec_system/specs/phase39-session06-boss-and-finale-contracts/security-compliance.md` | Security and GDPR compliance report. | \~91 | | `.spec_system/specs/phase39-session06-boss-and-finale-contracts/validation.md` | Validation report. | \~339 | ### Files Modified | File | Changes | | -------------------------------------------------------------------------- | ------------------------------------------------------------------------------------- | | `.spec_system/state.json` | Marked Session 06 complete, cleared current session, and recorded completion history. | | `.spec_system/PRD/phase_39/PRD_phase_39.md` | Updated Phase 39 progress to 6/8 sessions and added Session 06 completion notes. | | `.spec_system/PRD/phase_39/session_06_boss_and_finale_contracts.md` | Marked session complete and success criteria satisfied. | | `package.json` | Bumped version from `0.5.94` to `0.5.95`. | | `README.md` | Updated version line to `0.5.95`. | | `docs/CHANGELOG.md` | Added the Session 06 release entry. | | `src/extensions/ai-rogue/runtime/boss-presentation.ts` | Routed boss frames and finale display through boss/finale helpers. | | `src/extensions/ai-rogue/runtime/render-model.ts` | Used boss and finale helpers for render projection. | | `src/extensions/ai-rogue/runtime/renderer-audio-adapter.ts` | Used boss helpers for visible boss reveal detection. | | `src/extensions/ai-rogue/runtime/effects.ts` | Used boss helpers for actor and target event detection. | | `src/extensions/ai-rogue/runtime/combat.ts` | Used boss helpers for combat metadata and cue routing. | | `src/extensions/ai-rogue/runtime/content/types.ts` | Routed finale boss typing through the boss contract. | | `src/extensions/ai-rogue/runtime/content/validate.ts` | Validated finale boss references through boss specs. | | `src/extensions/ai-rogue/runtime/__tests__/boss-presentation.test.ts` | Added boss contract, frame parity, and finale gating coverage. | | `src/extensions/ai-rogue/runtime/__tests__/render-model.test.ts` | Added boss-spec frame and final-defense projection coverage. | | `src/extensions/ai-rogue/runtime/__tests__/renderer-audio-adapter.test.ts` | Added visible boss reveal coverage through boss helpers. | | `src/extensions/ai-rogue/runtime/__tests__/combat.test.ts` | Added boss combat metadata and cue parity coverage. | | `src/extensions/ai-rogue/runtime/__tests__/audio.test.ts` | Added boss audio family cue parity coverage. | | `src/extensions/ai-rogue/runtime/content/__tests__/levels.test.ts` | Added finale boss contract validation coverage. | *** ## Technical Decisions 1. **Boss contract owner**: Added `boss-contracts.ts` so boss identity, frames, sprite scale, audio, reveal, telegraph, shutdown, and finale projection stay centralized. 2. **Behavior-preserving migration**: Left compatibility wrappers for existing Kernel Sentinel helpers while moving internals and consumers to generic boss helpers. 3. **Authored finale ownership**: Final-defense display now uses authored level finale metadata, with safe fallbacks for synthetic or already-won snapshots. *** ## Test Results | Metric | Value | | --------------------------------- | ------------- | | Focused Vitest | 93 passed | | Full Vitest | 4655 passed | | Playwright AI Rogue runtime smoke | 16 passed | | Typecheck | Passed | | Script typecheck | Passed | | Lint | Passed | | Coverage | Not collected | *** ## Lessons Learned 1. Boss and finale behavior can be centralized without changing Kernel Sentinel gameplay, visuals, audio, pathing, or win conditions. 2. Authored level metadata is the right owner for final-defense presentation; raw depth gates obscure the difference between boss placement and finale ownership. *** ## Future Considerations Items for future sessions: 1. Add new bosses or minibosses only through boss specs, enemy templates, frame metadata, audio mappings, and focused tests. 2. Keep real content expansion in Session 07 metadata-backed before widening render, audio, combat, or save-schema behavior. *** ## Session Statistics * **Tasks**: 20 completed * **Files Created**: 8 * **Files Modified**: 20 * **Tests Added**: Focused boss, render, audio, combat, and content 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-session06-boss-and-finale-contracts/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.
