### Task T004 - Extend accepted and rejected G5 crop decisions

**Started**: 2026-06-29 02:51 **Completed**: 2026-06-29 02:57 **Duration**: 6 minutes

**Notes**:

* Added manifest-first G5 decisions for Kernel Sentinel idle, charge, telegraph, attack, line-fire FX, shielded, hit, and shutdown presentation.
* Added final-defense arena, target, payload compile, objective lock, objective progress, payload activation, payload core, survived, and win-unlock presentation frames.
* Rejected full-beam entity compression, detached beam sparks, red result column, and large cyan column candidates where they would read as text-like diagnostics, failure state, or unclear compressed silhouettes.
* Kept all G5 accepted frames in the gameplay atlas so UI atlas ownership remains unchanged unless a later task proves UI-owned markers are needed.

**Files Changed**:

* `docs/ongoing-projects/generated/ai-rogue-visual-audio-assets/crop-manifest.json` - Added 26 G5 boss/final-defense review entries: 22 accepted gameplay frames and 4 rejected decisions.
* `.spec_system/specs/phase37-session03-g5-boss-presentation/implementation-notes.md` - Recorded manifest decision evidence.

**Verification**:

* Command/check: `jq '{frameCount: (.frames|length), accepted: ([.frames[] | select(.status=="accepted")] | length), rejected: ([.frames[] | select(.status=="rejected")] | length), g5: ([.frames[] | select(.sourceFile|contains("boss-final-defense"))] | length)}' docs/ongoing-projects/generated/ai-rogue-visual-audio-assets/crop-manifest.json`
  * Result: PASS - Updated manifest parses and counts are coherent.
  * Evidence: 176 total frames, 159 accepted, 17 rejected, 26 G5 source entries.
* Command/check: `jq -r '.frames[] | select(.sourceFile|contains("boss-final-defense")) | [.frameName,.atlas,.category,.status,(.targetSize|@json)] | @tsv' docs/ongoing-projects/generated/ai-rogue-visual-audio-assets/crop-manifest.json`
  * Result: PASS - G5 decisions include required boss and final-defense states.
  * Evidence: Listed accepted boss idle/charge/telegraph/attack/line-fire/shielded/hit/shutdown entries, accepted final-defense marker/fx entries, and four rejected entries.
* Command/check: `view_image /tmp/g5-proposed.png`
  * Result: PASS - Candidate crops reviewed at runtime target sizes.
  * Evidence: Accepted 16x16/32x32/48x16 crops remained visually distinct; rejected candidates were too wide, ambiguous, or text-like at target size.
* UI product-surface check: N/A - Manifest updates do not mount user-facing copy or diagnostics.
* UI craft check: PASS - Candidate crops were reviewed at target runtime scale and no baked gameplay text was accepted.

**BQC Fixes**:

* Contract alignment: Rejected ambiguous full-beam and text-like marker candidates before adding typed runtime contracts.

### Task T005 - Regenerate gameplay atlas and docs preview

**Started**: 2026-06-29 02:57 **Completed**: 2026-06-29 02:59 **Duration**: 2 minutes

**Notes**:

* Ran the manifest-first packer after adding G5 crop decisions.
* Regenerated gameplay atlas metadata/image and docs production atlas preview.
* UI atlas content remained at 115 frames because no accepted G5 UI entries were added.
* Gameplay atlas grew from 197 to 214 frames because 22 accepted G5 entries include 5 overrides of existing boss frame names and 17 net-new gameplay frame names.

**Files Changed**:

* `src/assets/ai-rogue/gameplay-atlas.png` - Regenerated gameplay atlas with accepted G5 boss and final-defense frames.
* `src/assets/ai-rogue/gameplay-atlas.json` - Regenerated TexturePacker metadata for 214 gameplay frames.
* `docs/extensions/ai-rogue/generated/ai-rogue-production-atlas-preview.png` - Regenerated docs preview with the expanded gameplay atlas.
* `.spec_system/specs/phase37-session03-g5-boss-presentation/implementation-notes.md` - Recorded atlas generation evidence.

**Verification**:

  * Evidence: Reported gameplay 214 frames at 512x212 and 87,737 bytes; UI 115 frames at 512x140 and 24,672 bytes; manifest 159 accepted and 17 rejected; preview 145,905 bytes.
* Command/check: `jq -n --slurpfile gameplay src/assets/ai-rogue/gameplay-atlas.json --slurpfile ui src/assets/ai-rogue/ui-atlas.json '{gameplay: {count: ($gameplay[0].frames|length), size: $gameplay[0].meta.size}, ui: {count: ($ui[0].frames|length), size: $ui[0].meta.size}}'`
  * Result: PASS - Atlas JSON metadata matches packer output.
  * Evidence: Gameplay count 214 with 512x212 size; UI count 115 with 512x140 size.
* Command/check: `jq '.frames | with_entries(select(.key|test("boss_kernel_sentinel|fx_boss_kernel|final_defense")))' src/assets/ai-rogue/gameplay-atlas.json`
  * Result: PASS - G5 frames are present in gameplay atlas metadata.
  * Evidence: Metadata includes `boss_kernel_sentinel_telegraph_0`, `boss_kernel_sentinel_shielded_0`, `boss_kernel_sentinel_shutdown_0`, `fx_boss_kernel_sentinel_line_fire`, and accepted `final_defense_*` frames.
* Command/check: `stat -c '%n %s' src/assets/ai-rogue/gameplay-atlas.png src/assets/ai-rogue/ui-atlas.png docs/extensions/ai-rogue/generated/ai-rogue-production-atlas-preview.png`
  * Result: PASS - Runtime image assets remain under the 200 KB media-policy cap.
  * Evidence: Gameplay atlas 87,737 bytes; UI atlas 24,672 bytes; docs preview 145,905 bytes.
* UI product-surface check: N/A - Atlas regeneration did not mount route-visible diagnostics.
* UI craft check: PASS - Regenerated preview includes G5 runtime-scale sprites with no accepted baked text.

**BQC Fixes**:

* Contract alignment: Verified every accepted G5 frame named by the manifest appears in atlas metadata before adding TypeScript contracts.

### Task T006 - Update typed G5 frame contracts

**Started**: 2026-06-29 02:59 **Completed**: 2026-06-29 03:00 **Duration**: 1 minute

**Notes**:

* Added typed G5 boss state, boss FX, final-defense marker, payload, and combined gameplay frame-name unions.
* Added exhaustive constants for the G5 frame groups using `satisfies` checks to keep names aligned with declared unions.
* Wired `AI_ROGUE_G5_GAMEPLAY_FRAME_NAMES` into the required gameplay atlas contract while leaving simulation frame vocabulary unchanged because these new states are presentation-boundary overrides, not persisted or simulation-owned entity frame state.
* Investigated the focused asset test failure after the contract update; it is the expected old `totalFrames: 197` assertion and will be corrected in T015.

**Files Changed**:

* `src/extensions/ai-rogue/runtime/types-assets.ts` - Added G5 frame-name unions and exhaustive constants.
* `src/extensions/ai-rogue/runtime/assets.ts` - Added G5 gameplay frame constants to required gameplay atlas validation.
* `.spec_system/specs/phase37-session03-g5-boss-presentation/implementation-notes.md` - Recorded contract verification evidence.

**Verification**:

* Command/check: `bun run typecheck`
  * Result: PASS - TypeScript contracts compile.
  * Evidence: `tsc --noEmit` completed with exit code 0.
* Command/check: `rg -n "AiRogueG5|AI_ROGUE_G5|fx_boss_kernel|final_defense" src/extensions/ai-rogue/runtime/types-assets.ts src/extensions/ai-rogue/runtime/assets.ts`
  * Result: PASS - New G5 unions/constants and required-frame wiring are present.
  * Evidence: Found `AiRogueG5BossStateFrameName`, `AiRogueG5FinalDefenseMarkerFrameName`, `AiRogueG5PayloadFrameName`, `AI_ROGUE_G5_GAMEPLAY_FRAME_NAMES`, and required-frame import/wiring.
* Command/check: `bunx vitest run src/extensions/ai-rogue/runtime/__tests__/assets.test.ts`
  * Result: FAIL - Existing test still asserts the pre-G5 frame count.
  * Evidence: 11 tests passed, 1 failed because expected `totalFrames: 197` and received `totalFrames: 214`; this is scheduled for T015 atlas test update.
* UI product-surface check: N/A - Type contract updates did not change a user-facing route.
* UI craft check: N/A - Type contract updates did not change UI presentation.

**BQC Fixes**:

* Contract alignment: Added typed frame-name unions and `satisfies` constants so runtime mapping and tests can share the same accepted G5 frame contract.

### Task T007 - Add boss and final-defense presentation helpers

**Started**: 2026-06-29 03:00 **Completed**: 2026-06-29 03:07 **Duration**: 7 minutes

**Notes**:

* Added a pure `boss-presentation.ts` helper module for Kernel Sentinel frame selection and final-defense marker/payload frame selection.
* Boss frame priority is deterministic: shutdown, hit, shielded, attack, pending telegraph, recent charge, then idle fallback.
* Event windows are bounded by turn count so stale combat log entries fall back to idle instead of leaving the boss visually stuck.
* Final-defense helpers derive arena, target, objective progress, payload-active, and win-unlock frames from existing snapshot objective status and audio-cued events.
* Fixed a shutdown predicate issue before completing the task so a normal boss hit does not classify as shutdown.

**Files Changed**:

* `src/extensions/ai-rogue/runtime/boss-presentation.ts` - Added typed G5 boss and final-defense presentation selection helpers.
* `.spec_system/specs/phase37-session03-g5-boss-presentation/implementation-notes.md` - Recorded helper implementation evidence.

**Verification**:

* Command/check: `bun run typecheck`
  * Result: PASS - New helper module typechecks.
  * Evidence: `tsc --noEmit` completed with exit code 0 after helper creation and predicate fix.
* Command/check: `sed -n '1,320p' src/extensions/ai-rogue/runtime/boss-presentation.ts`
  * Result: PASS - Helper code inspected for presentation-only scope.
  * Evidence: The module reads event/snapshot facts and returns frame names; it does not mutate simulation state or persisted data.
* UI product-surface check: N/A - Helper module is not mounted into a route yet.
* UI craft check: N/A - Runtime presentation wiring happens in later tasks.

**BQC Fixes**:

* Contract alignment: Helper return types use `AiRogueG5BossStateFrameName`, `AiRogueG5FinalDefenseMarkerFrameName`, and `AiRogueG5PayloadFrameName`.
* State freshness on re-entry: Recent boss events expire after `AI_ROGUE_BOSS_PRESENTATION_EVENT_WINDOW_TURNS`, preventing stale attack/hit frames.

***

### Task T008 - Add focused boss-presentation tests

**Started**: 2026-06-29 03:07 **Completed**: 2026-06-29 03:08 **Duration**: 1 minute

**Notes**:

* Added focused tests for Kernel Sentinel idle fallback, expired event fallback, charge, telegraph, attack, shielded, hit, and shutdown frame selection.
* Added final-defense tests for objective lock/progress frames, payload activation, and win-unlock frame selection.
* Fixed the test objective fixture to use the existing `seal-exit` objective union instead of widening to `string`.

**Files Changed**:

* `src/extensions/ai-rogue/runtime/__tests__/boss-presentation.test.ts` - Added focused G5 boss and final-defense presentation tests.
* `.spec_system/specs/phase37-session03-g5-boss-presentation/implementation-notes.md` - Recorded test evidence.

**Verification**:

* Command/check: `bunx prettier --write src/extensions/ai-rogue/runtime/__tests__/boss-presentation.test.ts`
  * Result: PASS - Test file formatted.
  * Evidence: Prettier completed with exit code 0.
* Command/check: `bunx vitest run src/extensions/ai-rogue/runtime/__tests__/boss-presentation.test.ts`
  * Result: PASS - Focused boss-presentation suite passes.
  * Evidence: 1 test file passed; 5 tests passed.
* Command/check: `bun run typecheck`
  * Result: PASS - New tests and helper compile.
  * Evidence: `tsc --noEmit` completed with exit code 0 after fixing the objective fixture.
* UI product-surface check: N/A - Tests did not change a route.
* UI craft check: N/A - Runtime presentation wiring happens in later tasks.

**BQC Fixes**:

* Contract alignment: Test fixtures now use the existing objective id union and typed event/audio cue contracts.

***

### Task T009 - Wire Kernel Sentinel render-model frame overrides

**Started**: 2026-06-29 03:08 **Completed**: 2026-06-29 03:10 **Duration**: 2 minutes

**Notes**:

* Wired `selectKernelSentinelFrame` into entity projection for visible Kernel Sentinel sprites.
* Frame selection now derives charge, telegraph, attack, shielded, hit, shutdown, and idle fallback frames from existing snapshot turn, combat log events, pending threats, and status effects.
* Did not change entity footprint, sprite scale, pathing, simulation state, or persisted data shape; width/height still derive from existing `spriteScale`.

**Files Changed**:

* `src/extensions/ai-rogue/runtime/render-model.ts` - Uses the G5 boss presentation helper at the render boundary.
* `.spec_system/specs/phase37-session03-g5-boss-presentation/implementation-notes.md` - Recorded render-model wiring evidence.

**Verification**:

* Command/check: `bunx prettier --write src/extensions/ai-rogue/runtime/render-model.ts`
  * Result: PASS - Render-model file formatted.
  * Evidence: Prettier completed with exit code 0.
* Command/check: `bun run typecheck`
  * Result: PASS - Render-model helper integration compiles.
  * Evidence: `tsc --noEmit` completed with exit code 0.
* Command/check: `bunx vitest run src/extensions/ai-rogue/runtime/__tests__/boss-presentation.test.ts`
  * Result: PASS - Shared helper behavior remains stable after render-model import.
  * Evidence: 1 test file passed; 5 tests passed.
* Command/check: `sed -n '430,470p' src/extensions/ai-rogue/runtime/render-model.ts`
  * Result: PASS - Footprint and scale are preserved.
  * Evidence: Width/height still use `viewport.tileSize * spriteScale`; only `frameName` is overridden for Kernel Sentinel.
* UI product-surface check: N/A - Runtime route browser proof is scheduled for T020/T021.
* UI craft check: PASS - Render projection now points to distinct G5 state frames without adding route-visible diagnostics.

**BQC Fixes**:

* Contract alignment: Render-model uses the typed G5 presentation helper instead of ad hoc frame strings.
* State freshness on re-entry: Boss frame override falls back through the helper's bounded event window.

***

### Task T010 - Wire final-defense render and HUD presentation

**Started**: 2026-06-29 03:10 **Completed**: 2026-06-29 03:15 **Duration**: 5 minutes

**Notes**:

* Added final-defense render-model sprites for arena, target, objective progress, payload activation, and win unlock.
* Sprites use stable IDs and z-order after pending threats, with product-facing labels only.
* Added a shared final-defense relevance check so render-model and HUD only switch to G5 final-defense markers when final-floor/final-defense facts are present.
* HUD objective icon/descriptors use the G5 objective frame during final-defense presentation while retaining existing UI icons for normal objectives.

**Files Changed**:

* `src/extensions/ai-rogue/runtime/boss-presentation.ts` - Added shared final-defense relevance check.
* `src/extensions/ai-rogue/runtime/render-model.ts` - Added final-defense sprite projection.

* `.spec_system/specs/phase37-session03-g5-boss-presentation/implementation-notes.md` - Recorded final-defense wiring evidence.

**Verification**:

* Command/check: `bunx prettier --write src/extensions/ai-rogue/runtime/render-model.ts src/extensions/ai-rogue/runtime/render-hud.ts src/extensions/ai-rogue/runtime/boss-presentation.ts`
  * Result: PASS - Changed files formatted.
  * Evidence: Prettier completed with exit code 0.
* Command/check: `bun run typecheck`
  * Result: PASS - Final-defense render/HUD wiring compiles.
  * Evidence: `tsc --noEmit` completed with exit code 0.
* Command/check: `bunx vitest run src/extensions/ai-rogue/runtime/__tests__/boss-presentation.test.ts`
  * Result: PASS - Shared final-defense helper behavior remains stable.
  * Evidence: 1 test file passed; 5 tests passed.
* Command/check: `sed -n '780,930p' src/extensions/ai-rogue/runtime/render-model.ts`
  * Result: PASS - Render-model final-defense sprite IDs and labels inspected.
  * Evidence: Uses `final-defense:arena`, `final-defense:target`, `final-defense:objective`, `final-defense:payload`, and `final-defense:win-unlock` with product labels.
* Command/check: `sed -n '130,180p' src/extensions/ai-rogue/runtime/render-hud.ts` and `sed -n '265,325p' src/extensions/ai-rogue/runtime/render-hud.ts`
  * Result: PASS - HUD final-defense frame selection inspected.
  * Evidence: Normal objective icons remain UI-owned; final-defense objective marker switches to gameplay atlas only when relevant.
* UI product-surface check: N/A - Browser route proof is scheduled for T020/T021.
* UI craft check: PASS - Runtime projection uses visible G5 target/progress/payload sprites without debug text.

**BQC Fixes**:

* Contract alignment: Render-model and HUD share `selectFinalDefensePresentation` and `shouldShowFinalDefensePresentation`.
* Product surface discipline: Added only player-facing labels and no route-visible diagnostic/proof copy.

### Task T011 - Wire boss and payload transient effects

**Started**: 2026-06-29 03:15 **Completed**: 2026-06-29 03:20 **Duration**: 5 minutes

**Notes**:

* Routed boss hit, fire, charge, and shutdown events to G5 transient impact frames.
* Routed payload compile and final-defense survived events to G5 payload activation and win-unlock transient frames.
* Used existing `spawnImpact`, `spawnParticles`, `triggerShake`, `triggerFlash`, and `triggerHitStop` paths only; no new timers, subscriptions, containers, or external resources were introduced.
* Cleanup remains owned by `destroyTransientEffects`, `clearTransient`, and `destroy`.

**Files Changed**:

* `src/extensions/ai-rogue/runtime/effects.ts` - Added boss/final-defense transient routing and boss metadata helpers.
* `.spec_system/specs/phase37-session03-g5-boss-presentation/implementation-notes.md` - Recorded transient effects evidence.

  * Result: PASS - Event routing inspected.
  * Evidence: Attack, defeat, status, threat, and win branches spawn G5 boss/payload impact frames from existing events.
* Command/check: `sed -n '780,840p' src/extensions/ai-rogue/runtime/effects.ts`
  * Result: PASS - Cleanup path inspected.
  * Evidence: `clearTransient()` calls `destroyTransientEffects({ floats, impacts, particles })`; `destroy()` calls `clearTransient()`.
* UI product-surface check: N/A - Browser route proof is scheduled for T020/T021.
* UI craft check: PASS - Transient effects use gameplay sprites and no route-visible diagnostic text.

**BQC Fixes**:

* Resource cleanup: New effects use existing TTL-managed impact/particle arrays and existing transient cleanup.
* Contract alignment: Boss effect routing keys off existing audio cues and audio metadata, not new simulation fields.

### Task T012 - Wire final-defense cinematic win-unlock presentation

**Started**: 2026-06-29 03:20 **Completed**: 2026-06-29 03:22 **Duration**: 2 minutes

**Notes**:

* Updated the persistent victory/end-screen cinematic to prefer the accepted G5 `final_defense_win_unlock_0` gameplay texture for the win badge.
* Kept victory/defeat title, stats, and prompt rendered as Pixi text, not baked into the image frame.
* Preserved the existing UI glyph fallback if the gameplay texture is unavailable.

**Files Changed**:

* `src/extensions/ai-rogue/runtime/effects-cinematics.ts` - Added gameplay texture support and G5 win-unlock badge selection.
* `src/extensions/ai-rogue/runtime/effects.ts` - Passes gameplay textures into the cinematic layout.
* `.spec_system/specs/phase37-session03-g5-boss-presentation/implementation-notes.md` - Recorded cinematic evidence.

**Verification**:

* Command/check: `bunx prettier --write src/extensions/ai-rogue/runtime/effects-cinematics.ts src/extensions/ai-rogue/runtime/effects.ts`
  * Result: PASS - Cinematic/effects files formatted.
  * Evidence: Prettier completed with exit code 0.
* Command/check: `bun run typecheck`
  * Result: PASS - Cinematic texture contract compiles.
  * Evidence: `tsc --noEmit` completed with exit code 0.
* Command/check: `rg -n "layoutAiRogueEndScreen|gameplayTextures" src/extensions/ai-rogue/runtime/effects.ts src/extensions/ai-rogue/runtime/effects-cinematics.ts`
  * Result: PASS - Runtime texture handoff inspected.
  * Evidence: `effects.ts` passes `deps.gameplayTextures`; `effects-cinematics.ts` reads `final_defense_win_unlock_0`.
* UI product-surface check: N/A - Browser route proof is scheduled for T020/T021.
* UI craft check: PASS - The accepted image remains iconographic; product copy stays rendered text, not baked into the asset.

**BQC Fixes**:

* Contract alignment: Cinematic layout now receives the gameplay texture map explicitly instead of assuming all badges live in the UI atlas.

### Task T013 - Update renderer sprite lifecycle and G5 idle cycling

**Started**: 2026-06-29 03:23 **Completed**: 2026-06-29 03:25 **Duration**: 2 minutes

**Notes**:

* Updated Kernel Sentinel idle animation to cycle only through the accepted G5 idle frame contract instead of the legacy three-frame idle prefix.
* Treated `final-defense:*` projection sprites as transient renderer-owned sprites so stale final-defense markers are destroyed on scope changes instead of hidden indefinitely.
* Added lifecycle coverage for final-defense cleanup and direct animation coverage proving the old `boss_kernel_sentinel_idle_2` fallback is not selected by the G5 idle loop.

**Files Changed**:

* `src/extensions/ai-rogue/runtime/renderer-sprites.ts` - Added typed G5 idle-frame cycling and final-defense transient cleanup.
* `src/extensions/ai-rogue/runtime/__tests__/renderer-lifecycle.test.ts` - Added final-defense cleanup and G5 idle animation regression coverage.
* `.spec_system/specs/phase37-session03-g5-boss-presentation/implementation-notes.md` - Recorded renderer lifecycle evidence.

**Verification**:

* Command/check: `bunx vitest run src/extensions/ai-rogue/runtime/__tests__/renderer-lifecycle.test.ts`
  * Result: PASS - Renderer lifecycle suite passed.
  * Evidence: 1 test file passed; 10 tests passed.
* Command/check: `bun run typecheck`
  * Result: PASS - Renderer lifecycle changes compile.
  * Evidence: `tsc --noEmit` completed with exit code 0.
* UI product-surface check: N/A - Browser route proof is scheduled for T020/T021.
* UI craft check: PASS - Renderer animation keeps accepted G5 gameplay frames and does not introduce route-visible copy or diagnostic text.

**BQC Fixes**:

* Resource cleanup: Stale final-defense projection sprites now follow the transient destruction path.
* Contract alignment: Boss idle animation uses `AI_ROGUE_G5_BOSS_IDLE_FRAME_NAMES` instead of prefix-based legacy frame discovery.

***

### Task T014 - Verify combat and final-defense presentation ownership

**Started**: 2026-06-29 03:25 **Completed**: 2026-06-29 03:26 **Duration**: 1 minute

**Notes**:

* Verified no combat or simulation code was changed for the G5 presentation handoff.
* Boss frame selection reads only existing entity snapshot fields, recent combat-log events, pending sentry threats, status effects, and combat audio metadata.
* Final-defense presentation reads only existing snapshot depth/status/objective/floor-objective fields plus existing `compile_payload` and `final_defense_survived` combat-log audio cues.
* Effects routing reads existing event audio cues and audio metadata; it does not add new simulation-owned boss or final-defense state.
* Existing simulation still owns payload compile and win/loss behavior through `compile_payload`, `final_defense_survived`, status, pending threats, and combat log events.

**Files Changed**:

* `.spec_system/specs/phase37-session03-g5-boss-presentation/implementation-notes.md` - Documented combat/simulation ownership boundary and verification evidence.

**Verification**:

* Command/check: `git diff -- src/extensions/ai-rogue/runtime/combat.ts src/extensions/ai-rogue/runtime/simulation.ts`
  * Result: PASS - No combat or simulation implementation diff.
  * Evidence: Command produced no diff output.
* Command/check: `rg -n "boss_kernel_sentinel|final_defense|selectKernelSentinelFrame|selectFinalDefensePresentation|shouldShowFinalDefensePresentation|audioMetadata|pendingThreats|compile_payload|final_defense_survived" src/extensions/ai-rogue/runtime/boss-presentation.ts src/extensions/ai-rogue/runtime/render-model.ts src/extensions/ai-rogue/runtime/render-hud.ts src/extensions/ai-rogue/runtime/effects.ts src/extensions/ai-rogue/runtime/combat.ts src/extensions/ai-rogue/runtime/simulation.ts`
  * Result: PASS - Ownership boundary inspected.
  * Evidence: Presentation helpers are called from render/HUD/effects paths and consume existing snapshot/event/threat/audio fields; simulation emits the existing compile and survived cues.
* UI product-surface check: N/A - Browser route proof is scheduled for T020/T021.
* UI craft check: N/A - Documentation-only ownership verification did not alter UI presentation.

**BQC Fixes**:

* Contract alignment: Confirmed G5 visuals remain presentation-owned and do not introduce new simulation state or diagnostics.

***

### Task T015 - Update focused atlas contract tests

**Started**: 2026-06-29 03:26 **Completed**: 2026-06-29 03:27 **Duration**: 1 minute

**Notes**:

* Updated the committed gameplay atlas validation expectation from 197 to 214 frames after the G5 atlas regeneration.
* Added required-frame coverage for all 22 accepted G5 gameplay frames and verified those names are included in the runtime required-frame list.
* Added G5 TexturePacker metadata checks for compact, unrotated boss state, line-fire, arena, target, objective, payload, and win-unlock frames.

**Files Changed**:

* `src/extensions/ai-rogue/runtime/__tests__/assets.test.ts` - Updated atlas counts and added G5 frame/metadata contract coverage.
* `.spec_system/specs/phase37-session03-g5-boss-presentation/implementation-notes.md` - Recorded atlas test evidence.

**Verification**:

* Command/check: `bunx prettier --write src/extensions/ai-rogue/runtime/__tests__/assets.test.ts`
  * Result: PASS - Asset test file formatted.
  * Evidence: Prettier completed with exit code 0.
* Command/check: `bunx vitest run src/extensions/ai-rogue/runtime/__tests__/assets.test.ts`
  * Result: PASS - Focused asset suite passed.
  * Evidence: 1 test file passed; 14 tests passed.
* Command/check: `bun run typecheck`
  * Result: PASS - Atlas test changes compile.
  * Evidence: `tsc --noEmit` completed with exit code 0.
* UI product-surface check: N/A - Test-only atlas coverage did not change route behavior.
* UI craft check: PASS - Metadata coverage enforces compact unrotated runtime sprites for accepted G5 frames.

**BQC Fixes**:

* Contract alignment: The focused asset suite now fails if an accepted G5 frame is missing from metadata or the required-frame list.

***

### Task T016 - Update focused render-model tests

**Started**: 2026-06-29 03:27 **Completed**: 2026-06-29 03:31 **Duration**: 4 minutes

**Notes**:

* Updated the existing Kernel Sentinel projection assertion so pending threats now surface the G5 telegraph frame.
* Added focused render-model coverage for G5 boss idle, charge, telegraph, attack, shielded, hit, and shutdown frame overrides derived from existing snapshot/event/status inputs.
* Added final-defense projection coverage for arena, target, objective progress, payload active, and win-unlock sprites.
* Verified deterministic final-defense sprite ordering, gameplay-atlas ownership, route-safe labels, and HUD objective descriptor/icon behavior.

**Files Changed**:

* `src/extensions/ai-rogue/runtime/__tests__/render-model.test.ts` - Added G5 boss and final-defense render projection coverage.

  * Result: PASS - Focused render-model suite passed.
  * Evidence: 1 test file passed; 18 tests passed.
* Command/check: `bun run typecheck`
  * Result: PASS - Render-model test changes compile.
  * Evidence: `tsc --noEmit` completed with exit code 0.
* UI product-surface check: N/A - Test-only projection coverage did not run browser routes.
* UI craft check: PASS - Tests assert final-defense labels are product-facing and free of debug/telemetry/frame/seed wording.

**BQC Fixes**:

* Behavior coverage: Render projection now has focused regression coverage for every G5 boss override and final-defense sprite ordering.

***

### Task T017 - Update combat and final-defense behavior tests

**Started**: 2026-06-29 03:31 **Completed**: 2026-06-29 03:33 **Duration**: 2 minutes

**Notes**:

* Extended combat metadata coverage to prove Kernel Sentinel attacks still use boss audio cues/metadata and pierce shield buffer without consuming it.
* Extended final-defense behavior coverage to assert compile-payload and survived/win audio cues on the win path.
* Extended the compile-loss test to assert the compile payload fires, final-defense survived does not fire, and win-unlock presentation is not projected after a loss.
* Added snapshot-to-render checks in final-defense tests for target, payload, win-unlock, and Final Defense HUD descriptor behavior.

**Files Changed**:

* `src/extensions/ai-rogue/runtime/__tests__/combat.test.ts` - Added Sentinel shield-piercing/audio no-drift assertions.
* `src/extensions/ai-rogue/runtime/__tests__/biome-final.test.ts` - Added compile/win/loss event and final-defense projection assertions.

### Task T020 - Run desktop AI Rogue browser proof

**Started**: 2026-06-29 03:34 **Completed**: 2026-06-29 03:39 **Duration**: 5 minutes

**Notes**:

* Added a desktop browser-side projection proof for the G5 boss states and final-defense markers.
* The new browser proof imports the runtime modules through Vite inside Chromium, projects deterministic snapshots, and asserts boss charge/attack/shielded/hit/shutdown frames plus final-defense target, payload active, and win-unlock frames.
* The proof asserts final-defense sprites use gameplay atlas feedback layers, remain in viewport bounds, and expose product-facing labels only.
* The default Playwright port was already occupied, so the desktop proof was rerun with alternate ports.

**Files Changed**:

## Candidate Review

* Accepted G5 boss states: `boss_kernel_sentinel_idle_0`, `boss_kernel_sentinel_idle_1`, `boss_kernel_sentinel_charge_0`, `boss_kernel_sentinel_telegraph_0`, `boss_kernel_sentinel_attack_0`, `boss_kernel_sentinel_shielded_0`, `boss_kernel_sentinel_hit_0`, `boss_kernel_sentinel_shutdown_0`.
* Accepted G5 boss FX: `fx_boss_kernel_sentinel_line_fire`.
* Accepted final-defense frames: `final_defense_arena_0`, `final_defense_target_0`, `final_defense_payload_compile_0`, `final_defense_objective_lock_0`, `final_defense_objective_progress_0`, `final_defense_objective_progress_1`, `final_defense_objective_progress_2`, `final_defense_objective_progress_3`, `final_defense_payload_active_0`, `final_defense_win_unlock_0`, `final_defense_payload_core_0`, `final_defense_survived_0`, `final_defense_victory_0`.
* Rejected G5 candidates: `rejected_g5_full_beam_entity`, `rejected_g5_detached_beam_sparks`, `rejected_g5_red_result_column`, `rejected_g5_large_cyan_column`.

***

## Manifest Decisions

* 22 accepted G5 gameplay frames added.
* 4 rejected G5 decisions added.
* No G5 UI atlas entries added; current choices are gameplay/world presentation frames.

***

## Validation Commands

* PASS `python3 scripts/extensions/ai-rogue/pack-visual-assets.py` - gameplay 214 frames, UI 115 frames, manifest 159 accepted / 17 rejected.
* PASS `bun run typecheck` - `tsc --noEmit`.
* PASS `scripts/check-asset-sizes.sh` - all assets within configured size limits, total 15M.
* PASS focused Vitest acceptance command - 5 files / 49 tests.
* PASS desktop Playwright AI Rogue runtime suite on ports 5289/5290 - 13 tests.
* PASS mobile Playwright AI Rogue suite on ports 5291/5292 - 6 tests.
* PASS final docs/typecheck/hygiene checks.

***

## Browser Evidence

* Desktop PASS `PLAYWRIGHT_PORT=5289 PLAYWRIGHT_PUBLIC_DEMO_PORT=5290 bunx playwright test tests/e2e/ai-rogue-runtime.spec.ts --project=chromium` - 13 tests, including G5 boss/final-defense projection proof.
* Mobile PASS `PLAYWRIGHT_PORT=5291 PLAYWRIGHT_PUBLIC_DEMO_PORT=5292 bunx playwright test tests/e2e/ai-rogue-mobile.spec.ts --project=chromium` - 6 tests, including G5 readability and overflow proof.

***

## Design Decisions

* G5 boss and final-defense visuals are presentation-owned. Runtime rendering reads existing snapshot, combat-log, pending-threat, status, and audio-metadata signals rather than adding new combat/simulation state.

***

## Blockers & Solutions

* Default Playwright port 5189 was occupied during the desktop browser proof. The suite passed after rerunning on alternate ports 5289/5290; the mobile suite used ports 5291/5292.
