Session 03 owns registry validation; Session 05 owns enemy audio and Kernel Sentinel frame metadata. * Command/check: `sed -n '1,220p' .spec_system/specs/phase39-session02-depth-resolver-migration/implementation-notes.md .spec_system/specs/phase39-session03-registry-validation-and-save-parity/implementation-notes.md .spec_system/specs/phase39-session05-enemy-metadata-and-derived-asset-checks/implementation-notes.md` * Result: PASS - Implementation artifacts confirm prerequisite sessions completed with no blockers. * Evidence: Session 02 reports 20 / 20 tasks, Session 03 reports 16 / 16 tasks, and Session 05 reports 18 / 18 tasks. * UI product-surface check: N/A - Session artifact verification only; no user-facing route changed. * UI craft check: N/A - No UI changed. **BQC Fixes**: * N/A - No application code changed in this task. *** ### Task T002 - Inventory current Kernel Sentinel and final-defense literal callsites **Started**: 2026-06-30 23:02 **Completed**: 2026-06-30 23:03 **Duration**: 1 minute **Notes**: * Located literal Kernel Sentinel checks in boss presentation, render model, renderer audio, effects, combat, world generation, content validation, and tests. * Identified migration targets where boss identity is the only reason for the branch: `boss-presentation.ts`, `render-model.ts`, `renderer-audio-adapter.ts`, `effects.ts`, `combat.ts`, and `content/validate.ts`. * Identified final-defense presentation ownership currently includes `snapshot.depth >= 3` in `shouldShowFinalDefensePresentation()`, while authored finale metadata marks depth 4 as final. * Kept world-generation `kernel-sentinel` references out of scope because this session preserves current boss placement and pathing behavior. **Files Changed**: * `.spec_system/specs/phase39-session06-boss-and-finale-contracts/tasks.md` - Marked T002 complete and updated progress. * `.spec_system/specs/phase39-session06-boss-and-finale-contracts/implementation-notes.md` - Recorded T002 callsite inventory evidence. **Verification**: * Command/check: `rg -n "kernel-sentinel|Kernel Sentinel|isKernelSentinel|selectKernelSentinel|depth >= 3|depth > 3|final-defense|finalDefense|isFinalAuthoredLevel|finale" src/extensions/ai-rogue/runtime .spec_system/PRD/phase_39/session_06_boss_and_finale_contracts.md` * Result: PASS - Current literal boss and finale callsites were inventoried before source edits. * Evidence: Runtime matches include `boss-presentation.ts`, `render-model.ts`, `render-hud.ts`, `renderer-audio-adapter.ts`, `effects.ts`, `combat.ts`, `content/types.ts`, and `content/validate.ts`. * Command/check: targeted inspection of `src/extensions/ai-rogue/runtime/boss-presentation.ts`, `render-model.ts`, `render-hud.ts`, `renderer-audio-adapter.ts`, `effects.ts`, `combat.ts`, `content/types.ts`, and `content/validate.ts` * Result: PASS - Confirmed which branches are presentation/audio/combat identity routing versus placement or fixture assertions. * Evidence: Boss frame priority and raw final-defense depth fallback are centralized in `boss-presentation.ts`; downstream consumers call those helpers or use direct literal checks. * UI product-surface check: N/A - Source inventory only; no user-facing route changed. * UI craft check: N/A - No UI changed. **BQC Fixes**: * N/A - No application code changed in this task. *** ### Task T003 - Confirm boss frame metadata and finale level metadata source facts **Started**: 2026-06-30 23:03 **Completed**: 2026-06-30 23:04 **Duration**: 1 minute **Notes**: * Confirmed `AI_ROGUE_ENEMY_TEMPLATES["kernel-sentinel"]` owns `audioFamily: "boss"`, `spriteScale: 2`, and `bossFrameSet` values for idle, charge, telegraph, attack, shielded, hit, and shutdown. * Confirmed `bossFrameSetForEnemyKind()` already exposes boss frame metadata from enemy templates. * Confirmed `AI_ROGUE_LEVEL_SPECS` marks depth 4 `firewall-gauntlet` as `finale.isFinalAuthoredLevel: true`, `bossKind: "kernel-sentinel"`, and `requiresFloorObjectiveClear: true`. * Confirmed depth 3 still places Kernel Sentinel as an exit guard but is not the authored finale, so final-defense presentation must not be owned by raw `depth >= 3`. **Files Changed**: * `.spec_system/specs/phase39-session06-boss-and-finale-contracts/tasks.md` - Marked T003 complete and updated progress. * `.spec_system/specs/phase39-session06-boss-and-finale-contracts/implementation-notes.md` - Recorded T003 source-fact evidence. **Verification**: * Command/check: `sed -n '180,250p' src/extensions/ai-rogue/runtime/entities.ts` * Result: PASS - Kernel Sentinel template contains the boss metadata needed for the contract. * Evidence: The template includes boss audio family, sprite scale 2, shield-pierce behavior, and the seven boss frame groups. * Command/check: `sed -n '1,180p' src/extensions/ai-rogue/runtime/content/levels.ts` * Result: PASS - Authored level specs contain the finale metadata needed for presentation routing. * Evidence: Depth 4 is the only `isFinalAuthoredLevel: true` level and owns the finale boss; depth 3 keeps Kernel Sentinel placement without finale ownership. * Command/check: `rg -n "bossFrameSetForEnemyKind|standardEnemyFrameSetForKind|audioFamilyForEnemyKind|bossFrameSet|spriteScale|kernel-sentinel" src/extensions/ai-rogue/runtime/entities.ts src/extensions/ai-rogue/runtime/types-entities.ts src/extensions/ai-rogue/runtime/audio.ts` * Result: PASS - Existing lookup and metadata ownership points were identified. * Evidence: `bossFrameSetForEnemyKind()` returns template `bossFrameSet`; audio family routing still projects from enemy metadata. * UI product-surface check: N/A - Source-fact verification only; no user-facing route changed. * UI craft check: N/A - No UI changed. **BQC Fixes**: * Contract alignment: Confirmed contract data sources before introducing the wrapper module, avoiding duplicated literal frame data in consumers. *** ### Task T004 - Create typed boss and finale contract helpers **Started**: 2026-06-30 23:04 **Completed**: 2026-06-30 23:07 **Duration**: 3 minutes **Notes**: * Added `AiRogueBossSpec`, `AiRogueBossEnemyKind`, `AI_ROGUE_BOSS_ENEMY_KINDS`, `bossSpecForEnemyKind()`, and `isBossEnemyKind()`. * Projected Kernel Sentinel from enemy template metadata, including boss frame set, presentation frames, sprite scale, boss audio family, reveal cue, telegraph cue, attack cue, hit cue, and shutdown cue. * Added non-throwing finale helpers that use `authoredLevelSpecForDepth()` and return a presentation spec only for authored final levels. * Kept the single boss kind literal inside the contract module so downstream runtime consumers can avoid local boss identity branches. **Files Changed**: * `src/extensions/ai-rogue/runtime/boss-contracts.ts` - Added typed boss and authored-finale contract helpers. * `.spec_system/specs/phase39-session06-boss-and-finale-contracts/tasks.md` - Marked T004 complete and updated progress. * `.spec_system/specs/phase39-session06-boss-and-finale-contracts/implementation-notes.md` - Recorded T004 evidence. **Verification**: * Command/check: `bun run typecheck` * Result: PASS - TypeScript accepted the new boss and finale contract module. * Evidence: `tsc --noEmit` completed successfully. * Command/check: `bun -e "import { AI_ROGUE_BOSS_ENEMY_KINDS, bossSpecForEnemyKind, isBossEnemyKind, finalePresentationSpecForDepth } from './src/extensions/ai-rogue/runtime/boss-contracts.ts'; const spec = bossSpecForEnemyKind('kernel-sentinel'); console.log(JSON.stringify({ kinds: AI_ROGUE_BOSS_ENEMY_KINDS, isBoss: isBossEnemyKind('kernel-sentinel'), unknown: bossSpecForEnemyKind('errant-process'), spriteScale: spec?.spriteScale, idle: spec?.presentationFrameSet.idle, finaleDepth3: finalePresentationSpecForDepth(3), finaleDepth4: finalePresentationSpecForDepth(4)?.boss?.kind }));"` * Result: PASS - Boss lookup, unknown fallback, presentation idle frames, and finale gating behaved as expected. * Evidence: Output showed Kernel Sentinel as the only boss, `errant-process` as null, sprite scale 2, depth 3 finale null, and depth 4 finale boss `kernel-sentinel`. * UI product-surface check: N/A - Runtime contract module only; no user-facing route changed. * UI craft check: N/A - No UI changed. **BQC Fixes**: * Contract alignment: The boss contract reads enemy template and authored level metadata instead of duplicating frame, audio, or finale state in consumers. *** ### Task T005 - Implement boss-spec-based frame selection **Started**: 2026-06-30 23:07 **Completed**: 2026-06-30 23:10 **Duration**: 3 minutes **Notes**: * Added generic `isBossEntity()` and `selectBossFrame()` helpers in `boss-presentation.ts`. * Reworked Kernel Sentinel frame priority through `AiRogueBossSpec` presentation frames while preserving the existing shutdown, hit, shielded, attack, pending telegraph, charge, idle order. * Kept legacy `isKernelSentinelEntity()` and `selectKernelSentinelFrame()` wrappers delegating to the generic helpers for compatibility until consumers migrate. * Preserved unknown-kind fallback behavior by returning the default boss idle presentation frame. **Files Changed**: * `src/extensions/ai-rogue/runtime/boss-presentation.ts` - Routed boss frame selection through boss specs and generic metadata matching. * `.spec_system/specs/phase39-session06-boss-and-finale-contracts/tasks.md` - Marked T005 complete and updated progress. * `.spec_system/specs/phase39-session06-boss-and-finale-contracts/implementation-notes.md` - Recorded T005 evidence. **Verification**: * Command/check: `bunx vitest run src/extensions/ai-rogue/runtime/__tests__/boss-presentation.test.ts` * Result: PASS - Existing Kernel Sentinel frame and finale presentation tests passed. * Evidence: 1 test file passed; 6 tests passed. * Command/check: `rg -n "kernel-sentinel|boss_kernel_sentinel|selectKernelSentinel|isKernelSentinel|depth >= 3" src/extensions/ai-rogue/runtime/boss-presentation.ts` * Result: PASS - Kernel Sentinel frame literals were removed from frame-selection internals; only compatibility wrapper names and the pre-existing final-defense depth gate remained. * Evidence: Matches were `isKernelSentinelEntity`, `selectKernelSentinelFrame`, and `snapshot.depth >= 3`. * UI product-surface check: N/A - Runtime projection helper only; no route-visible UI changed. * UI craft check: N/A - No UI layout or copy changed. **BQC Fixes**: * Contract alignment: Boss frame selection now reads the declared boss presentation contract instead of hard-coded Kernel Sentinel frame literals. *** ### Task T006 - Implement authored-finale display helpers **Started**: 2026-06-30 23:10 **Completed**: 2026-06-30 23:11 **Duration**: 1 minute **Notes**: * Replaced the raw `snapshot.depth >= 3` final-defense presentation gate with `finalePresentationSpecForDepth(snapshot.depth)`. * Removed floor-objective-only ownership from final-defense display routing so non-final authored floors with objectives do not show finale markers by default. * Preserved non-throwing invalid-depth fallback behavior for synthetic snapshots that already contain won status or final-defense audio events. **Files Changed**: * `src/extensions/ai-rogue/runtime/boss-presentation.ts` - Routed final-defense display gating through authored finale metadata. * `.spec_system/specs/phase39-session06-boss-and-finale-contracts/tasks.md` - Marked T006 complete and updated progress. * `.spec_system/specs/phase39-session06-boss-and-finale-contracts/implementation-notes.md` - Recorded T006 evidence. **Verification**: * Command/check: `bunx vitest run src/extensions/ai-rogue/runtime/__tests__/boss-presentation.test.ts` * Result: PASS - Existing boss presentation suite remained green after the finale gate migration. * Evidence: 1 test file passed; 6 tests passed. * Command/check: `bun -e "import { shouldShowFinalDefensePresentation } from './src/extensions/ai-rogue/runtime/boss-presentation.ts'; const base = { combatLog: [], floorObjective: { kind: 'purge-dumps', label: 'Purge', target: 2, progress: 0, isComplete: false }, status: 'active' }; console.log(JSON.stringify({ depth3: shouldShowFinalDefensePresentation({ ...base, depth: 3 }), depth4: shouldShowFinalDefensePresentation({ ...base, depth: 4 }), invalidWon: shouldShowFinalDefensePresentation({ ...base, depth: 99, status: 'won' }) }));"` * Result: PASS - Authored finale gating and invalid-depth fallback behaved as intended. * Evidence: Output was `{"depth3":false,"depth4":true,"invalidWon":true}`. * UI product-surface check: N/A - Runtime projection gate only; route-visible smoke is deferred until render/HUD consumers migrate. * UI craft check: N/A - No UI layout or copy changed. **BQC Fixes**: * Contract alignment: Final-defense display ownership now comes from authored finale metadata instead of an unrelated depth comparison. *** ### Task T007 - Update content finale boss typing **Started**: 2026-06-30 23:12 **Completed**: 2026-06-30 23:13 **Duration**: 1 minute **Notes**: * Changed `AiRogueLevelFinaleSpec.bossKind` to use `AiRogueBossEnemyKind | null`. * Kept the import type-only so content types do not add runtime renderer, route, bridge, telemetry, or save-shape dependencies. * Did not add any persisted save fields; finale boss metadata remains derived from authored level specs. **Files Changed**: * `src/extensions/ai-rogue/runtime/content/types.ts` - Replaced local boss extraction with the boss contract kind type. * `.spec_system/specs/phase39-session06-boss-and-finale-contracts/tasks.md` - Marked T007 complete and updated progress. * `.spec_system/specs/phase39-session06-boss-and-finale-contracts/implementation-notes.md` - Recorded T007 evidence. **Verification**: * Command/check: `bun run typecheck` * Result: PASS - TypeScript accepted the content finale boss type migration. * Evidence: `tsc --noEmit` completed successfully. * Command/check: `sed -n '1,40p' src/extensions/ai-rogue/runtime/content/types.ts` * Result: PASS - `AiRogueLevelFinaleSpec.bossKind` now uses the boss contract type through an `import type`. * Evidence: The file imports `AiRogueBossEnemyKind` and declares `bossKind: AiRogueBossEnemyKind | null`. * UI product-surface check: N/A - Type-only content contract change; no user-facing route changed. * UI craft check: N/A - No UI changed. **BQC Fixes**: * Contract alignment: Finale boss typing now depends on the declared boss contract instead of an independent local literal extraction. *** ### Task T008 - Update content registry finale boss validation **Started**: 2026-06-30 23:13 **Completed**: 2026-06-30 23:15 **Duration**: 2 minutes **Notes**: * Removed the local finale boss set from `content/validate.ts`. * Added `validateNullableBossReference()` so finale boss references are accepted only when `bossSpecForEnemyKind()` resolves a declared boss spec. * Preserved existing safe issue mapping: malformed or unknown finale boss values still report `invalid-boss-reference` at the `finale.bossKind` path without echoing unsafe values. **Files Changed**: * `src/extensions/ai-rogue/runtime/content/validate.ts` - Validates finale boss references through the boss contract. * `.spec_system/specs/phase39-session06-boss-and-finale-contracts/tasks.md` - Marked T008 complete and updated progress. * `.spec_system/specs/phase39-session06-boss-and-finale-contracts/implementation-notes.md` - Recorded T008 evidence. **Verification**: * Command/check: `bunx vitest run src/extensions/ai-rogue/runtime/content/__tests__/levels.test.ts` * Result: PASS - Content registry validation tests passed. * Evidence: 1 test file passed; 7 tests passed. * Command/check: `bun run typecheck` * Result: PASS - TypeScript accepted the validation import and helper. * Evidence: `tsc --noEmit` completed successfully. * Command/check: `rg -n "AI_ROGUE_BOSS_ENEMY_KINDS|validateNullableBossReference|bossSpecForEnemyKind" src/extensions/ai-rogue/runtime/content/validate.ts` * Result: PASS - Local boss set was removed and validation now routes through `bossSpecForEnemyKind()`. * Evidence: Matches show the boss contract import and `validateNullableBossReference()` implementation only. * UI product-surface check: N/A - Content validation logic only; no user-facing route changed. * UI craft check: N/A - No UI changed. **BQC Fixes**: * Trust boundary enforcement: Finale boss references crossing from authored content into validation are checked with an explicit local schema/type guard and boss contract lookup. * Contract alignment: Validation now depends on the same boss spec registry as runtime projection. *** ### Task T009 - Replace render-model boss and final-defense projection branches **Started**: 2026-06-30 23:15 **Completed**: 2026-06-30 23:16 **Duration**: 1 minute **Notes**: * Replaced the render-model Kernel Sentinel entity check with `isBossEnemyKind()` and `selectBossFrame()`. * Kept final-defense sprite projection behind `shouldShowFinalDefensePresentation()`, which now uses authored finale metadata. * Confirmed projected final-defense labels remain product-facing labels such as "Final defense arena", "Objective progress", "Payload active", and "Win unlock". **Files Changed**: * `src/extensions/ai-rogue/runtime/render-model.ts` - Routed boss frames through boss helpers and retained authored-finale display gating. * `.spec_system/specs/phase39-session06-boss-and-finale-contracts/tasks.md` - Marked T009 complete and updated progress. * `.spec_system/specs/phase39-session06-boss-and-finale-contracts/implementation-notes.md` - Recorded T009 evidence. **Verification**: * Command/check: `bunx vitest run src/extensions/ai-rogue/runtime/__tests__/render-model.test.ts` * Result: PASS - Render model projection suite passed. * Evidence: 1 test file passed; 22 tests passed. * Command/check: `rg -n "kernel-sentinel|selectKernelSentinel|depth >= 3|final-defense" src/extensions/ai-rogue/runtime/render-model.ts` * Result: PASS - No Kernel Sentinel literal branch or raw depth gate remains in render-model. * Evidence: Matches are only the product-facing final-defense sprite IDs. * UI product-surface check: PASS - Source inspection of projected sprite labels confirmed normal render labels remain product-facing and contain no debug, seed, path, telemetry, or frame readouts. * UI craft check: PASS - No layout, sizing, responsive behavior, or visible UI copy was changed; existing render projection tests remained green. **BQC Fixes**: * Contract alignment: Boss render frames now consume the boss contract helper instead of a local identity branch. * Product surface discipline: Final-defense projection labels remain product-facing only. *** ### Task T010 - Replace HUD final-defense gating with authored finale helpers **Started**: 2026-06-30 23:16 **Completed**: 2026-06-30 23:17 **Duration**: 1 minute **Notes**: * Verified `render-hud.ts` already routed final-defense HUD state through `shouldShowFinalDefensePresentation()` and `selectFinalDefensePresentation()`. * T006 migrated that shared helper to authored finale metadata, so HUD objective icons and descriptors now inherit the authored finale gate without a redundant local edit. * Confirmed HUD depth text remains run context copy, not final-defense ownership logic. **Files Changed**: * `.spec_system/specs/phase39-session06-boss-and-finale-contracts/tasks.md` - Marked T010 complete and updated progress. * `.spec_system/specs/phase39-session06-boss-and-finale-contracts/implementation-notes.md` - Recorded T010 evidence. **Verification**: * Command/check: `rg -n "depth >= 3|snapshot.depth|shouldShowFinalDefensePresentation|selectFinalDefensePresentation|finalDefensePresentation" src/extensions/ai-rogue/runtime/render-hud.ts` * Result: PASS - HUD has no local raw final-defense depth gate and uses the shared authored-finale helper. * Evidence: Matches show helper calls at HUD projection and descriptor sites; `snapshot.depth` appears only in product-facing run context text. * Command/check: `bunx vitest run src/extensions/ai-rogue/runtime/__tests__/render-model.test.ts` * Result: PASS - Render model and HUD projection coverage remained green. * Evidence: 1 test file passed; 22 tests passed. * UI product-surface check: PASS - Source inspection confirmed HUD labels remain product-facing and no debug, seed, path, telemetry, or frame readouts were introduced. * UI craft check: PASS - No HUD layout, sizing, responsive behavior, or visible copy was changed. **BQC Fixes**: * Contract alignment: HUD final-defense display depends on the shared authored-finale gate instead of owning a separate condition. *** ### Task T011 - Replace renderer audio visible-boss reveal detection **Started**: 2026-06-30 23:17 **Completed**: 2026-06-30 23:18 **Duration**: 1 minute **Notes**: * Replaced the renderer audio `kernel-sentinel` visibility check with `bossSpecForEnemyKind()` and `revealBehavior.isVisibleRevealTracked`. * Preserved transition-only behavior by leaving the previous-snapshot to current-snapshot comparison unchanged. **Files Changed**: * `src/extensions/ai-rogue/runtime/renderer-audio-adapter.ts` - Uses boss helper metadata for visible boss reveal detection. * `.spec_system/specs/phase39-session06-boss-and-finale-contracts/tasks.md` - Marked T011 complete and updated progress. * `.spec_system/specs/phase39-session06-boss-and-finale-contracts/implementation-notes.md` - Recorded T011 evidence. **Verification**: * Command/check: `bunx vitest run src/extensions/ai-rogue/runtime/__tests__/renderer-audio-adapter.test.ts` * Result: PASS - Renderer audio adapter suite passed. * Evidence: 1 test file passed; 11 tests passed. * Command/check: `rg -n "kernel-sentinel|stinger_boss_reveal|bossSpecForEnemyKind|hasVisibleBoss" src/extensions/ai-rogue/runtime/renderer-audio-adapter.ts` * Result: PASS - No boss-kind literal remains in renderer audio reveal detection. * Evidence: Matches show only the boss contract import and `hasVisibleBoss()` helper. * UI product-surface check: N/A - Audio adapter behavior only; no route-visible UI changed. * UI craft check: N/A - No UI changed. **BQC Fixes**: * Contract alignment: Visible boss reveal audio now follows the declared boss reveal behavior instead of a local enemy-kind literal. *** ### Task T012 - Replace effects boss actor and target detection **Started**: 2026-06-30 23:18 **Completed**: 2026-06-30 23:19 **Duration**: 1 minute **Notes**: * Replaced effects-layer Kernel Sentinel metadata checks with `isBossEnemyKind()` for actor and target enemy metadata. * Preserved missing-metadata fallback behavior by keeping boss audio cue checks for charge, fire, hit, and shutdown events. **Files Changed**: * `src/extensions/ai-rogue/runtime/effects.ts` - Uses boss helpers for boss actor and target detection. * `.spec_system/specs/phase39-session06-boss-and-finale-contracts/tasks.md` - Marked T012 complete and updated progress. * `.spec_system/specs/phase39-session06-boss-and-finale-contracts/implementation-notes.md` - Recorded T012 evidence. **Verification**: * Command/check: `bun run typecheck` * Result: PASS - TypeScript accepted the effects helper migration. * Evidence: `tsc --noEmit` completed successfully. * Command/check: `rg -n "kernel-sentinel|isBossEnemyKind|boss_charge|boss_fire|boss_hit|boss_shutdown" src/extensions/ai-rogue/runtime/effects.ts` * Result: PASS - No boss-kind literal remains; cue fallbacks remain for missing metadata. * Evidence: Matches show `isBossEnemyKind()` and the existing boss cue checks. * UI product-surface check: N/A - Effects routing only; no route-visible UI changed. * UI craft check: N/A - No UI changed. **BQC Fixes**: * Contract alignment: Effects boss actor/target detection now follows the shared boss kind contract while preserving cue-only fallback paths. *** ### Task T013 - Replace combat boss audio actor and boss cue branching **Started**: 2026-06-30 23:19 **Completed**: 2026-06-30 23:23 **Duration**: 4 minutes **Notes**: * Added required boss actor and attack cue accessors to `boss-contracts.ts`. * Routed `audioActorKindForEnemy()` through `isBossEnemyKind()` and `requiredBossAudioActorKindForEnemyKind()`. * Routed enemy attack cue selection through `requiredBossAttackCueForEnemyKind()`. * Also moved the combat alternate boss frame selection through `bossSpecForEnemyKind()` and `selectBossPresentationFrame()` so combat no longer owns a boss-kind literal. * Preserved Kernel Sentinel shield-pierce behavior because that remains template metadata on the enemy state and was not changed. **Files Changed**: * `src/extensions/ai-rogue/runtime/boss-contracts.ts` - Added required boss actor and attack cue accessors. * `src/extensions/ai-rogue/runtime/combat.ts` - Uses boss helpers for boss audio metadata, attack cues, and alternate boss frame projection. * `.spec_system/specs/phase39-session06-boss-and-finale-contracts/tasks.md` - Marked T013 complete and updated progress. * `.spec_system/specs/phase39-session06-boss-and-finale-contracts/implementation-notes.md` - Recorded T013 evidence. **Verification**: * Command/check: `bunx vitest run src/extensions/ai-rogue/runtime/__tests__/combat.test.ts` * Result: PASS - Combat suite passed. * Evidence: 1 test file passed; 8 tests passed. * Command/check: `bun run typecheck` * Result: PASS - TypeScript accepted the narrowed boss helper routing. * Evidence: `tsc --noEmit` completed successfully. * Command/check: `rg -n "kernel-sentinel|boss_fire|requiredBoss|isBossEnemyKind|bossSpecForEnemyKind|selectBossPresentationFrame" src/extensions/ai-rogue/runtime/combat.ts` * Result: PASS - No boss-kind literal or direct boss cue branch remains in combat. * Evidence: Matches show only boss helper imports and calls. * UI product-surface check: N/A - Combat metadata and frame routing only; no route-visible UI changed. * UI craft check: N/A - No UI changed. **BQC Fixes**: * Contract alignment: Combat boss metadata and cue routing now follows the boss contract, and the remaining boss alternate frame projection uses the same presentation contract as rendering. *** ### Task T014 - Ensure boss audio family cue routing remains metadata-backed **Started**: 2026-06-30 23:23 **Completed**: 2026-06-30 23:25 **Duration**: 2 minutes **Notes**: * Verified `audio.ts` still resolves enemy cue families through `enemyAudioFamilyForKind()` and therefore through enemy template metadata. * Verified Kernel Sentinel boss cue asset parity remains covered by the existing audio test suite. * No `audio.ts` source edit was required because the intended metadata-backed routing already existed from Session 05 and remained compatible with the new boss contract. **Files Changed**: * `.spec_system/specs/phase39-session06-boss-and-finale-contracts/tasks.md` - Marked T014 complete and updated progress. * `.spec_system/specs/phase39-session06-boss-and-finale-contracts/implementation-notes.md` - Recorded T014 evidence. **Verification**: * Command/check: `bunx vitest run src/extensions/ai-rogue/runtime/__tests__/audio.test.ts` * Result: PASS - Audio suite passed. * Evidence: 1 test file passed; 33 tests passed. * Command/check: `sed -n '912,1010p' src/extensions/ai-rogue/runtime/audio.ts` * Result: PASS - Boss attack, telegraph, hit, and shutdown cue routing derives from `audioFamilyForEnemyKind()`, which calls `enemyAudioFamilyForKind()`. * Evidence: The inspected code maps the `"boss"` audio family to `boss_fire`, `boss_charge`, `boss_hit`, and `boss_shutdown`. * Command/check: `rg -n "export function|function .*Cue|audioFamilyForEnemyKind|enemyAudioFamilyForKind|describe\\(\\\".*boss|boss_fire|boss_charge|boss_hit|boss_shutdown" src/extensions/ai-rogue/runtime/audio.ts src/extensions/ai-rogue/runtime/__tests__/audio.test.ts` * Result: PASS - Source and tests cover boss cue asset names and metadata-backed audio family routing. * Evidence: Matches include `enemyAudioFamilyForKind()` usage in `audio.ts` and audio tests covering boss charge, fire, hit, and shutdown asset filenames. * UI product-surface check: N/A - Audio routing only; no route-visible UI changed. * UI craft check: N/A - No UI changed. **BQC Fixes**: * Contract alignment: Confirmed boss audio remains metadata-backed and unchanged for Kernel Sentinel cue parity. *** ### Task T015 - Add boss contract, frame parity, and finale gating coverage **Started**: 2026-06-30 23:25 **Completed**: 2026-06-30 23:26 **Duration**: 1 minute **Notes**: * Added boss contract assertions for Kernel Sentinel spec lookup, standard enemy rejection, boss audio cues, sprite scale, and presentation frame parity. * Switched boss-presentation frame assertions from the legacy Kernel Sentinel wrapper to generic `selectBossFrame()`. * Added authored finale ownership assertions for depth 3, depth 4, invalid depth, won fallback, and compile-payload fallback. **Files Changed**: * `src/extensions/ai-rogue/runtime/__tests__/boss-presentation.test.ts` - Added boss contract and authored finale gating coverage. * `.spec_system/specs/phase39-session06-boss-and-finale-contracts/tasks.md` - Marked T015 complete and updated progress. * `.spec_system/specs/phase39-session06-boss-and-finale-contracts/implementation-notes.md` - Recorded T015 evidence. **Verification**: * Command/check: `bunx vitest run src/extensions/ai-rogue/runtime/__tests__/boss-presentation.test.ts` * Result: PASS - Boss presentation suite passed. * Evidence: 1 test file passed; 10 tests passed. * Command/check: `rg -n "selectKernelSentinelFrame|bossSpecForEnemyKind|finalePresentationSpecForDepth|shouldShowFinalDefensePresentation|selectBossFrame" src/extensions/ai-rogue/runtime/__tests__/boss-presentation.test.ts` * Result: PASS - Tests assert the generic boss contract and no longer call the legacy frame wrapper. * Evidence: Matches show `bossSpecForEnemyKind`, `finalePresentationSpecForDepth`, `shouldShowFinalDefensePresentation`, and `selectBossFrame`; no `selectKernelSentinelFrame` match. * UI product-surface check: N/A - Unit test coverage only; no user-facing route changed. * UI craft check: N/A - No UI changed. **BQC Fixes**: * Contract alignment: Added tests that lock boss contract lookup, frame projection, and authored finale gating to the declared runtime contracts. *** ### Task T016 - Update render model boss-spec and finale coverage **Started**: 2026-06-30 23:26 **Completed**: 2026-06-30 23:27 **Duration**: 1 minute **Notes**: * Updated boss frame expectations to read from `bossSpecForEnemyKind("kernel-sentinel")`. * Changed final-defense projection coverage to use authored finale depth 4. * Added a negative case proving depth 3 objective floors do not project final-defense markers without authored finale ownership or explicit finale evidence. **Files Changed**: * `src/extensions/ai-rogue/runtime/__tests__/render-model.test.ts` - Added boss-spec frame and authored-finale projection coverage. * `.spec_system/specs/phase39-session06-boss-and-finale-contracts/tasks.md` - Marked T016 complete and updated progress. * `.spec_system/specs/phase39-session06-boss-and-finale-contracts/implementation-notes.md` - Recorded T016 evidence. **Verification**: * Command/check: `bunx vitest run src/extensions/ai-rogue/runtime/__tests__/render-model.test.ts` * Result: PASS - Render model suite passed. * Evidence: 1 test file passed; 23 tests passed. * Command/check: `rg -n "bossSpecForEnemyKind|depth: 4|depth: 3|final-defense|Kernel Sentinel G5" src/extensions/ai-rogue/runtime/__tests__/render-model.test.ts` * Result: PASS - Test coverage includes boss-spec frame assertions, depth 4 final-defense projection, and depth 3 non-finale negative coverage. * Evidence: Matches show the boss spec import, depth 4 finale projection, and the depth 3 no-final-defense assertion. * UI product-surface check: PASS - Render model labels remain product-facing; no debug, telemetry, seed, or frame labels were introduced. * UI craft check: PASS - Projection tests still validate deterministic ordering and HUD descriptor behavior; no layout or visual sizing code changed. **BQC Fixes**: * Contract alignment: Render tests now verify boss frames and final-defense projection against the declared boss and authored finale contracts. *** ### Task T017 - Update audio adapter, combat, and audio boss-helper tests **Started**: 2026-06-30 23:27 **Completed**: 2026-06-30 23:31 **Duration**: 4 minutes **Notes**: * Updated renderer audio adapter reveal tests to use `bossSpecForEnemyKind()` for the boss kind and to assert reveal behavior is enabled by the boss spec. * Updated combat metadata and cue tests to use boss contract kind and attack cue values. * Updated audio metadata SFX tests to use boss contract kind values and assert Kernel Sentinel boss cue parity remains `boss_charge`, `boss_fire`, `boss_hit`, and `boss_shutdown`. **Files Changed**: * `src/extensions/ai-rogue/runtime/__tests__/renderer-audio-adapter.test.ts` - Uses boss contract values for visible boss reveal tests. * `src/extensions/ai-rogue/runtime/__tests__/combat.test.ts` - Uses boss contract values for boss metadata and cue tests. * `src/extensions/ai-rogue/runtime/__tests__/audio.test.ts` - Uses boss contract values for boss metadata SFX tests and cue parity assertions. * `.spec_system/specs/phase39-session06-boss-and-finale-contracts/tasks.md` - Marked T017 complete and updated progress. * `.spec_system/specs/phase39-session06-boss-and-finale-contracts/implementation-notes.md` - Recorded T017 evidence. **Verification**: * Command/check: `bunx vitest run src/extensions/ai-rogue/runtime/__tests__/renderer-audio-adapter.test.ts` * Result: PASS - Renderer audio adapter suite passed. * Evidence: 1 test file passed; 11 tests passed. * Command/check: `bunx vitest run src/extensions/ai-rogue/runtime/__tests__/combat.test.ts` * Result: PASS - Combat suite passed. * Evidence: 1 test file passed; 8 tests passed. * Command/check: `bunx vitest run src/extensions/ai-rogue/runtime/__tests__/audio.test.ts` * Result: PASS - Audio suite passed. * Evidence: 1 test file passed; 33 tests passed. * Command/check: `rg -n "bossSpecForEnemyKind|kernel-sentinel|boss_fire|boss_reveal" src/extensions/ai-rogue/runtime/__tests__/renderer-audio-adapter.test.ts src/extensions/ai-rogue/runtime/__tests__/combat.test.ts src/extensions/ai-rogue/runtime/__tests__/audio.test.ts` * Result: PASS - Relevant boss helper tests now import the boss contract while retaining explicit Kernel Sentinel parity lookup values. * Evidence: Matches show `bossSpecForEnemyKind()` in all three suites and cue parity assertions in audio tests. * UI product-surface check: N/A - Test-only task; no user-facing route changed. * UI craft check: N/A - No UI changed. **BQC Fixes**: * Contract alignment: Audio adapter, combat, and audio tests now verify boss routing against the declared boss contract while preserving Kernel Sentinel cue parity. *** ### Task T018 - Update content registry finale boss contract tests **Started**: 2026-06-30 23:31 **Completed**: 2026-06-30 23:33 **Duration**: 2 minutes **Notes**: * Added a content registry test proving the authored finale boss resolves through `bossSpecForEnemyKind()`. * Added explicit assertions that a standard enemy and unsafe reference both produce `invalid-boss-reference` at `finale.bossKind`. * Kept existing unsafe-value redaction assertions intact. **Files Changed**: * `src/extensions/ai-rogue/runtime/content/__tests__/levels.test.ts` - Added finale boss contract validation coverage. * `.spec_system/specs/phase39-session06-boss-and-finale-contracts/tasks.md` - Marked T018 complete and updated progress. * `.spec_system/specs/phase39-session06-boss-and-finale-contracts/implementation-notes.md` - Recorded T018 evidence. **Verification**: * Command/check: `bunx vitest run src/extensions/ai-rogue/runtime/content/__tests__/levels.test.ts` * Result: PASS - Content registry suite passed. * Evidence: 1 test file passed;
