### Task T004 - Add enemy and boss cue prompt definitions

**Started**: 2026-06-28 16:13 **Completed**: 2026-06-28 16:16 **Duration**: 3 minutes

**Notes**:

* Added 12 compact ElevenLabs cue definitions for files 46-57 to the existing AI Rogue SFX generation script.
* Kept the existing scratch output, Ogg transcode, report, and skip-existing flow unchanged.
* Prompts specify short dry gameplay cues with no voice, music, or melody.

**Files Changed**:

* `scripts/generate-ai-rogue-audio-sfx.ts` - added cue definitions for fast, thief, corruption, sentry, and Kernel Sentinel boss SFX.
* `.spec_system/specs/phase36-session03-enemy-and-boss-sfx-pack/implementation-notes.md` - recorded generator evidence.

**Verification**:

* Command/check: `bun scripts/generate-ai-rogue-audio-sfx.ts --list | tail -n 14`
  * Result: PASS - generator lists existing 44-45 cues followed by new 46-57 cue files.
  * Evidence: output includes `enemy_fast_attack` through `boss_shutdown` mapped to `46_enemy_fast_attack.ogg` through `57_boss_shutdown.ogg`.
* BQC check: External dependency resilience
  * Result: PASS - this task only extends cue data; the existing script still loads `.env.local`, rejects missing API keys with an explicit error, and writes raw responses to gitignored scratch paths.
  * Evidence: code inspection confirmed `loadEnvLocal()`, `generateRawMp3()`, `transcodeToOgg()`, and `probe()` paths were not weakened.
* UI product-surface check: N/A - generation script only.
* UI craft check: N/A - no UI files changed.

***

### Task T005 - Extend simulation audio cue union

**Started**: 2026-06-28 16:16 **Completed**: 2026-06-28 16:18 **Duration**: 2 minutes

**Notes**:

* Added typed cue IDs for fast enemy attack/defeat, Packet Thief grab/escape, corruption attack/defeat, Firewall Sentry charge/fire, and Kernel Sentinel charge/fire/hit/shutdown.
* Kept the cue IDs additive so existing generic cues remain valid for legacy events and fallback behavior.

**Files Changed**:

* `src/extensions/ai-rogue/runtime/types-simulation.ts` - extended `AiRogueSimulationAudioCueId` with 12 new cue IDs.
* `src/extensions/ai-rogue/runtime/audio.ts` - updated in the same compatibility pass so the cue record remains exhaustive.
* `.spec_system/specs/phase36-session03-enemy-and-boss-sfx-pack/implementation-notes.md` - recorded cue union evidence.

**Verification**:

* Command/check: `rg -n 'enemy_fast_attack|enemy_thief_grab|enemy_corruption_attack|enemy_sentry_charge|boss_charge|boss_shutdown' src/extensions/ai-rogue/runtime/types-simulation.ts src/extensions/ai-rogue/runtime/audio.ts`
  * Result: PASS - new cue IDs are present in the simulation type contract and the runtime mapping file.
  * Evidence: output shows the new IDs in `types-simulation.ts` and `audio.ts`.
* Command/check: `bun run typecheck`
  * Result: PASS - TypeScript accepted the expanded cue union.
  * Evidence: `tsc --noEmit` completed with exit code 0.
* BQC check: Contract alignment
  * Result: PASS - adding the union and exhaustive map together prevents schema/enum drift.
  * Evidence: `Record<AiRogueSfxId, readonly string[]>` compiled after the union expansion.
* UI product-surface check: N/A - runtime type contract only.
* UI craft check: N/A - no UI files changed.

### Task T006 - Add SFX basename mappings for new cue IDs

**Started**: 2026-06-28 16:16 **Completed**: 2026-06-28 16:19 **Duration**: 3 minutes

**Notes**:

* Added SFX basename entries for all new cue IDs, mapping files 46-57 to the runtime cue contract.
* Preserved existing missing-asset behavior: `buildUrlLookup()` only includes URLs that Vite finds, and `playBuffer()` returns no-op when a URL is absent.

**Files Changed**:

* `src/extensions/ai-rogue/runtime/audio.ts` - added basename mappings for files 46-57.
* `.spec_system/specs/phase36-session03-enemy-and-boss-sfx-pack/implementation-notes.md` - recorded mapping evidence.

**Verification**:

* Command/check: `rg -n '46_enemy_fast_attack|47_enemy_fast_defeated|48_enemy_thief_grab|49_enemy_thief_escape|50_enemy_corruption_attack|51_enemy_corruption_defeated|52_enemy_sentry_charge|53_enemy_sentry_fire|54_boss_charge|55_boss_fire|56_boss_hit|57_boss_shutdown' src/extensions/ai-rogue/runtime/audio.ts`
  * Result: PASS - all new asset basenames are mapped in the SFX lookup contract.
  * Evidence: `audio.ts` contains each file basename from 46 through 57.
* Command/check: `bun run typecheck`
  * Result: PASS - the SFX basename record remains exhaustive for `AiRogueSfxId`.
  * Evidence: `tsc --noEmit` completed with exit code 0.
* BQC check: Failure path completeness
  * Result: PASS - missing generated assets remain silent-safe through the existing URL lookup and `playBuffer()` no-op path.
  * Evidence: `buildUrlLookup()` filters missing basenames and `playBuffer()` returns `null` when `url` is undefined.
* UI product-surface check: N/A - runtime mapping only.
* UI craft check: N/A - no UI files changed.

### Task T007 - Define enemy-kind-to-audio-family helpers

**Started**: 2026-06-28 16:19 **Completed**: 2026-06-28 16:23 **Duration**: 4 minutes

**Notes**:

* Added explicit family grouping for fast, thief, corruption, sentry, boss, and generic enemy kinds.
* Added cue helper functions for attack, telegraph, hit, and defeated routes while keeping unknown or generic enemy kinds on existing fallback cues.
* Kept the helpers inside `audio.ts` to avoid widening runtime imports from simulation/combat into the renderer-owned audio asset module.

**Files Changed**:

* `src/extensions/ai-rogue/runtime/audio.ts` - added enemy audio family classifier and cue helper functions.
* `.spec_system/specs/phase36-session03-enemy-and-boss-sfx-pack/implementation-notes.md` - recorded helper mapping evidence.

**Verification**:

* Command/check: `rg -n 'type AiRogueEnemyAudioFamily|audioFamilyForEnemyKind|enemyAttackCueForKind|enemyTelegraphCueForKind|enemyHitCueForKind|enemyDefeatedCueForKind' src/extensions/ai-rogue/runtime/audio.ts`
  * Result: PASS - audio family and cue helper functions are present.
  * Evidence: output shows the family type and all four cue helper functions in `audio.ts`.
* Command/check: `bun run typecheck`
  * Result: PASS - helper additions compile under strict TypeScript.
  * Evidence: `tsc --noEmit` completed with exit code 0.
* BQC check: Contract alignment
  * Result: PASS - every current `AiRogueEnemyKind` maps to exactly one family, with `errant-process` and missing kind mapped to generic fallback.
  * Evidence: switch coverage includes fast, thief, corruption, sentry, boss, `errant-process`, and `undefined`.
* UI product-surface check: N/A - runtime helper only.
* UI craft check: N/A - no UI files changed.

### Task T008 - Update combat event construction for family-specific explicit attack cues

**Started**: 2026-06-28 16:23 **Completed**: 2026-06-28 16:28 **Duration**: 5 minutes

**Notes**:

* Updated `resolveEnemyAttack()` so unshielded enemy attacks emit explicit family-specific attack cues.
* Preserved shield absorb and shield break explicit cues ahead of enemy-family cues when shield buffer takes damage.
* Kept RNG, damage, event order, event metadata, and simulation state unchanged.

**Files Changed**:

* `src/extensions/ai-rogue/runtime/combat.ts` - added family-specific explicit attack cue selection for enemy attacks.
* `.spec_system/specs/phase36-session03-enemy-and-boss-sfx-pack/implementation-notes.md` - recorded combat routing evidence.

**Verification**:

* Command/check: `rg -n 'enemyAttackCueForKind|enemy_fast_attack|enemy_thief_grab|enemy_corruption_attack|enemy_sentry_fire|boss_fire|shield_absorb|shield_break' src/extensions/ai-rogue/runtime/combat.ts`
  * Result: PASS - combat code emits family attack cues and preserves shield cue branches.
  * Evidence: `resolveEnemyAttack()` chooses shield cues when absorbed and otherwise calls `enemyAttackCueForKind(enemy.kind)`.
* Command/check: `bun run test -- src/extensions/ai-rogue/runtime/__tests__/combat.test.ts`
  * Result: PASS - focused combat tests still pass.
  * Evidence: 1 test file passed; 7 tests passed.
* Command/check: `bun run typecheck`
  * Result: PASS - combat cue changes compile.
  * Evidence: `tsc --noEmit` completed with exit code 0.
* BQC check: Contract alignment
  * Result: PASS - every current enemy kind maps to a valid `AiRogueSimulationAudioCueId`.
  * Evidence: TypeScript accepted the exhaustive switch and existing combat metadata tests still pass.
* UI product-surface check: N/A - simulation event construction only.
* UI craft check: N/A - no UI files changed.

## Routing Plan

| Family     | Enemy kinds                                                    | Attack / fire cue                                        | Telegraph cue         | Hit cue        | Defeated cue                |
| ---------- | -------------------------------------------------------------- | -------------------------------------------------------- | --------------------- | -------------- | --------------------------- |
| Fast       | `signal-gnat`, `ping-mosquito`, `index-skink`, `cache-wraith`  | `enemy_fast_attack`                                      | `telegraph` fallback  | `hit` fallback | `enemy_fast_defeated`       |
| Thief      | `packet-thief`                                                 | `enemy_thief_grab`                                       | `telegraph` fallback  | `hit` fallback | `enemy_thief_escape`        |
| Corruption | `corrupt-newt`, `venom-daemon`, `burst-toad`, `insight-beetle` | `enemy_corruption_attack`                                | `telegraph` fallback  | `hit` fallback | `enemy_corruption_defeated` |
| Sentry     | `firewall-sentry`                                              | `enemy_sentry_fire`                                      | `enemy_sentry_charge` | `hit` fallback | `enemy_defeated` fallback   |
| Boss       | `kernel-sentinel`                                              | `boss_fire`                                              | `boss_charge`         | `boss_hit`     | `boss_shutdown`             |
| Generic    | `errant-process`, missing kind, unknown metadata               | `enemy_melee` fallback or no-op when metadata is invalid | `telegraph` fallback  | `hit` fallback | `enemy_defeated` fallback   |

Fallback decisions:

* Explicit `event.audioCues` remain highest priority and may intentionally play multiple cues.
* Metadata-derived routing plays at most one cue per event and does not fall through to legacy message parsing.
* Unknown or incomplete metadata no-ops when actor/target intent does not match a supported route.
* Missing generated asset URLs remain silent-safe through the existing URL lookup and `playBuffer()` no-op path.
* Shield absorb and shield break cues keep precedence over family attack cues in combat event construction.

***

* Documented explicit cue precedence, single-cue metadata dispatch, no-op handling for invalid metadata, and silent missing-asset behavior.

**Files Changed**:

* `.spec_system/specs/phase36-session03-enemy-and-boss-sfx-pack/implementation-notes.md` - added routing plan and fallback decisions.

**Verification**:

* Command/check: `rg -n '## Routing Plan|enemy_fast_attack|enemy_thief_grab|enemy_corruption_attack|enemy_sentry_charge|boss_shutdown|Fallback decisions' .spec_system/specs/phase36-session03-enemy-and-boss-sfx-pack/implementation-notes.md`

  * Evidence: routing plan lists fast, thief, corruption, sentry, boss, and generic rows plus fallback decision bullets.
* UI product-surface check: N/A - spec-system notes only.
* UI craft check: N/A - no UI files changed.

### Task T011 - Inspect generated render metadata

**Started**: 2026-06-28 16:32 **Completed**: 2026-06-28 16:34 **Duration**: 2 minutes

**Notes**:

* Inspected report metadata and direct ffprobe output for all generated Ogg files.
* Accepted the batch because every cue is Ogg Opus, mono, 48000 Hz, under 1.3 seconds, and far below the 200 KB non-music cap.
* No cues were regenerated from metadata inspection. Final acoustic fatigue and mix-quality listening remains part of the later final audio validation session.

**Files Changed**:

* `.spec_system/specs/phase36-session03-enemy-and-boss-sfx-pack/implementation-notes.md` - recorded render inspection evidence.

**Verification**:

* Command/check: `jq -r '.cues[] | [.file, .render.codec, .render.channels, .render.sampleRate, .render.durationSeconds, .render.outputBytes] | @tsv' tmp/elevenlabs/ai-rogue-sfx/latest-generation-report.json`
  * Result: PASS - report metadata is valid for all generated cues.
  * Evidence: every cue reports `opus`, `1` channel, `48000` Hz, durations from 0.5265 to 1.2865 seconds, and output bytes from 4971 to 9096.
* Command/check: `jq '[.cues[] | select(.render.codec != "opus" or .render.channels != 1 or .render.sampleRate != "48000" or .render.outputBytes >= 204800 or .render.durationSeconds > 1.6)] | {failureCount:length, failures:map({file, render})}' tmp/elevenlabs/ai-rogue-sfx/latest-generation-report.json`
  * Result: PASS - no metadata failures found.
  * Evidence: command returned `failureCount: 0`.
* Command/check: `ffprobe -v error -show_entries stream=codec_name,channels,sample_rate:format=duration -of csv=p=0 [files 46-57]`
  * Result: PASS - direct file probes match generation report.
  * Evidence: every new Ogg reports `opus,48000,1` and durations from 0.526500 to 1.286500 seconds.
* BQC check: External dependency resilience
  * Result: PASS - generated outputs were validated before being accepted for runtime wiring.
  * Evidence: no oversized, stereo, wrong sample-rate, wrong codec, or too-long cues were found.
* UI product-surface check: N/A - asset inspection only.
* UI craft check: N/A - no UI files changed.

### Task T014 - Implement metadata-based cue selection

**Started**: 2026-06-28 16:22 **Completed**: 2026-06-28 16:24 **Duration**: 2 minutes

**Notes**:

* Wired metadata dispatch through the enemy-family helpers for attack, fire, telegraph, hit, and defeated paths.
* Sentry telegraph/fire now route to `enemy_sentry_charge` and `enemy_sentry_fire`; boss telegraph/fire/hit/shutdown route to `boss_charge`, `boss_fire`, `boss_hit`, and `boss_shutdown`.
* Fast, thief, and corruption metadata routes now use their family attack and defeated cues while generic enemies keep existing fallbacks.
* Invalid metadata combinations continue to no-op instead of falling through to message parsing.

**Files Changed**:

* `src/extensions/ai-rogue/runtime/audio.ts` - wired metadata cue selection to family/boss helpers and volume tuning.
* `src/extensions/ai-rogue/runtime/__tests__/audio.test.ts` - updated focused metadata expectations for sentry charge and boss shutdown routing.
* `.spec_system/specs/phase36-session03-enemy-and-boss-sfx-pack/implementation-notes.md` - recorded routing implementation evidence.

**Verification**:

* Command/check: `rg -n 'enemyAttackCueForMetadata|enemyFireCueForMetadata|enemyTelegraphCueForMetadata|enemyHitCueForTarget|enemyDefeatedCueForTarget|boss_shutdown|enemy_sentry_charge' src/extensions/ai-rogue/runtime/audio.ts`
  * Result: PASS - metadata route helpers and new boss/sentry cue paths are wired.
  * Evidence: `audio.ts` contains metadata selectors for attack/fire/telegraph/hit/defeated and returns `enemy_sentry_charge` plus `boss_shutdown`.
* Command/check: `bun run test -- src/extensions/ai-rogue/runtime/__tests__/audio.test.ts`
  * Result: PASS - focused audio metadata routing tests pass.
  * Evidence: 1 test file passed; 11 tests passed.
* Command/check: `bun run typecheck`
  * Result: PASS - metadata routing changes compile.
  * Evidence: `tsc --noEmit` completed with exit code 0.
* BQC check: Contract alignment and failure path completeness
  * Result: PASS - metadata dispatch now maps supported families to valid cue IDs and invalid metadata still no-ops without legacy double-trigger.
  * Evidence: focused audio test proves unknown metadata did not request shield fallback audio; typecheck proves cue IDs align.
* UI product-surface check: N/A - audio runtime routing only.
* UI craft check: N/A - no UI files changed.

**BQC Fixes**:

* Contract alignment: Updated the focused audio test from old generic sentry/boss expectations to the new identity cue contract (`src/extensions/ai-rogue/runtime/__tests__/audio.test.ts`).

* Confirmed missing URL behavior remains silent-safe through `selectVariantUrl()` and `playBuffer()`.

**Files Changed**:

* `.spec_system/specs/phase36-session03-enemy-and-boss-sfx-pack/implementation-notes.md` - recorded lifecycle preservation evidence.

**Verification**:

* Command/check: `rg -n 'unlock\\(\\)|setPreferences|playSfx\\(|decode\\(|playBuffer\\(|SFX_URLS|get\\(id\\)|muted|sfxVolume|return SILENT_ENGINE|catch \\{' src/extensions/ai-rogue/runtime/audio.ts`
  * Result: PASS - existing lifecycle and fallback paths remain present.
  * Evidence: output shows silent engine fallback, `unlock()`, `setPreferences()`, SFX volume gain, lazy decode, URL lookup, and catch/no-op branches.
* Command/check: `bun run test -- src/extensions/ai-rogue/runtime/__tests__/audio.test.ts`
  * Result: PASS - focused audio lifecycle and fallback tests pass.
  * Evidence: 1 test file passed; 11 tests passed.
* BQC check: Failure path completeness and resource cleanup
  * Result: PASS - fetch/decode failure, unavailable AudioContext, dispose-before-decode, heartbeat/music cleanup, and explicit no-op fallback coverage still pass.
  * Evidence: focused audio suite passed after adding new routes.
* UI product-surface check: N/A - audio lifecycle only.
* UI craft check: N/A - no UI files changed.

**Started**: 2026-06-28 16:32 **Completed**: 2026-06-28 16:35 **Duration**: 3 minutes

**Notes**:

* Added browser proof coverage to the existing AI Rogue runtime e2e spec for desktop 1440x1000 and mobile 390x844 viewports.
* The test starts the real Play route, installs a fake Web Audio context that still fetches real Ogg URLs, simulates fast, thief, corruption, sentry, and boss encounter events through the actual combat helpers, and verifies files 46-57 are fetched with source starts.
* Verified mute preference propagation by checking the Web Audio gain target reaches 0 after `setPreferences({ muted: true })`.
* Verified silent fallback by removing `AudioContext` and confirming a silent engine stays locked and does not fetch additional audio URLs.
* Updated `game-feel.md` after browser evidence was complete.

**Files Changed**:

* Command/check: `rg -n 'browser path verification confirmed|1440x1000|390x844|Session 08 human listening' docs/extensions/ai-rogue/game-feel.md`
  * Result: PASS - durable docs now record confirmed desktop/mobile browser evidence and Session 08 listening caveat.
  * Evidence: output shows confirmed browser path wording, desktop/mobile viewport sizes, and Session 08 ownership.
* Command/check: `bun -e "const text=await Bun.file('docs/extensions/ai-rogue/game-feel.md').text(); const bad=[...text].filter(ch=>ch.charCodeAt(0)>127); console.log(bad.length===0?'ascii-pass':'ascii-fail '+bad.slice(0,10).join(''))"`
  * Result: PASS - edited docs remain ASCII-only.
  * Evidence: command printed `ascii-pass`.
* BQC check: Failure path completeness and product surface discipline
  * Result: PASS - browser proof covers Web Audio unavailable fallback without adding debug UI or product-surface diagnostics.
  * Evidence: proof lives in e2e code and uses local DEV/runtime helpers; normal Play surface remains product-facing.
* UI product-surface check: PASS - Play route inspected in Chromium desktop and mobile through the e2e test, with no new visible debug UI added.
