### Task T020 - Complete runtime review notes

**Started**: 2026-06-28 20:27 **Completed**: 2026-06-28 20:28 **Duration**: 1 minute

**Notes**:

* Recorded runtime review evidence for repeated triggers, volume interaction, failed load/decode recovery, no product debug UI, and Session 08 handoff.
* Confirmed implementation evidence names the commands and checks used for audio routing, browser proof, static gates, and media metadata.
* Confirmed no external blocker remains for implementation; final acoustic listening remains Session 08 scope.

**Files Changed**:

* `.spec_system/specs/phase36-session07-adaptive-stinger-pack/implementation-notes.md` - Added runtime review notes and final task evidence.
* `.spec_system/specs/phase36-session07-adaptive-stinger-pack/tasks.md` - Marked final task and completion checklist complete.

**Verification**:

* Command/check: Review of T015-T019 evidence in this file.
  * Result: PASS - Runtime review categories are covered by implementation evidence.
  * Evidence: T015 covers URL selection, cooldown, volume/mute, failed fetch/decode, and dispose-before-decode; T018 covers browser source starts, silent fallback, failed requests, page errors, and product-surface copy; T019 covers static and asset gates.
* UI product-surface check: PASS - Focused Playwright proof passed on desktop and mobile and asserts no adaptive/ducking/sidechain implementation copy appears in normal Play route body.
* UI craft check: PASS - Browser proof mounted and started the Play route at desktop and mobile viewports with no page errors or failed non-data requests; no visible debug UI was introduced by this session.

***

## Runtime Review Notes

### Repeated Triggers

* Engine-level adaptive cooldowns remain unchanged for all seven request IDs.
* Focused test evidence: `prevents duplicate adaptive requests during cooldown` confirms a repeated `boss_reveal` request only fetches one dedicated `60_stinger_boss_reveal` URL inside the cooldown window.
* Adapter no-repeat tests still cover low HP, boss reveal, and terminal status transitions without repeated requests when previous/current state does not indicate a transition.

### Volume And Ducking Interaction

* Dedicated profile volumes are lower than or equal to the previous provisional cue levels, while cooldown and ducking windows remain unchanged.
* Focused test evidence confirms adaptive stingers still respect master mute and SFX volume, and preference changes during ducking recompute music/theme lane targets.
* Browser proof records gain target values and source starts through the fake AudioContext path on desktop and mobile.

### Load And Decode Recovery

* Failed adaptive stinger fetches and failed decodes are swallowed by the existing lazy decode path and do not throw.
* Dispose-before-decode coverage confirms a stinger source is not started after route/audio disposal.
* Silent no-Web-Audio fallback remains no-op safe and does not fetch additional audio.

### Product Surface

* The normal Play route does not expose adaptive-audio diagnostics, ducking copy, sidechain copy, render metadata, source-start counts, or readiness badges from this implementation.
* Browser proof confirms page errors and failed non-data requests are empty for the focused desktop/mobile audio proof.

### Session 08 Handoff

* Session 08 should perform final human listening for masking, fatigue, loudness balance, and whether the locally synthesized stingers should be replaced by credentialed external SFX masters.
* Implementation is complete without a runtime blocker; acoustic judgment is intentionally outside this agent-verifiable implementation pass.

### Task T019 - Run static gates, asset-size validation, and ASCII/LF checks

**Started**: 2026-06-28 20:25 **Completed**: 2026-06-28 20:27 **Duration**: 2 minutes

**Notes**:

* Ran application typecheck, script typecheck, lint, asset-size validation, and text encoding scans.
* Initial lint run found Prettier-only formatting issues in the new stinger generator and adapter test; ran Prettier on those files and reran lint successfully.
* Confirmed changed text artifacts are ASCII and have no CRLF line endings.

**Files Changed**:

  * Result: PASS - Text/source files report ASCII or JSON text data.
  * Evidence: `file` reported ASCII for Markdown/TypeScript files and JSON text data for JSON files.
* UI product-surface check: N/A - T019 was static verification only.
* UI craft check: N/A - T019 did not change a user-facing surface.

***

### Task T018 - Run desktop and mobile browser audio proof

**Started**: 2026-06-28 20:24 **Completed**: 2026-06-28 20:25 **Duration**: 1 minute

**Notes**:

* Ran the focused Playwright browser audio proof on desktop and mobile.
* Verified the proof fetches and starts the dedicated adaptive stinger basenames 58-64.
* Verified the proof still checks silent fallback, failed Ogg requests, page errors, and product-surface copy cleanliness.
* Playwright web server initially probed ports before startup, then completed normally with both tests passing.

**Files Changed**:

* `.spec_system/specs/phase36-session07-adaptive-stinger-pack/implementation-notes.md` - Recorded T018 browser proof evidence.

**Verification**:

* Command/check: `bunx playwright test tests/e2e/ai-rogue-runtime.spec.ts -g "AI Rogue browser audio pack fetches enemy, boss, and theme audio"`
  * Result: PASS - Desktop and mobile browser audio proof passed.
  * Evidence: 2 Chromium tests passed: desktop 1440x1000 and mobile 390x844.
* UI product-surface check: PASS - The Playwright proof asserts the normal Play route body does not contain `adaptive audio`, `ducking`, or `sidechain` implementation copy.
* UI craft check: PASS - The proof loads the Play route at desktop and mobile viewports, starts the runtime, and verifies no page errors or failed non-data requests while checking the audio proof path.

**BQC Fixes**:

* Failure path completeness: Browser proof includes silent no-Web-Audio fallback with no additional fetches.
* Product surface discipline: Browser proof keeps adaptive implementation diagnostics out of normal Play copy.

***

**Started**: 2026-06-28 20:18 **Completed**: 2026-06-28 20:20 **Duration**: 2 minutes

**Notes**:

* Updated the adaptive audio browser proof constants from Session 06 provisional cue basenames to dedicated stinger basenames 58-64.
* Updated browser proof failure messages to refer to dedicated stinger cues.
* Preserved desktop/mobile coverage, explicit Ogg request checks, source-start checks, silent fallback checks, failed-request capture, page-error capture, and product-copy cleanliness checks.

**Files Changed**:

* `tests/e2e/ai-rogue-runtime.spec.ts` - Updated adaptive browser proof basenames and messages for dedicated stingers.
* `.spec_system/specs/phase36-session07-adaptive-stinger-pack/implementation-notes.md` - Recorded T012 implementation evidence.

### Task T011 - Preserve existing audio behavior while stingers run

**Started**: 2026-06-28 20:10 **Completed**: 2026-06-28 20:20 **Duration**: 10 minutes

**Notes**:

* Preserved heartbeat, theme ambience, depth music, terminal music, one-shot SFX, mute, volume, autoplay unlock, lazy decode, and silent fallback behavior by routing stingers through existing `playSfx()` and adaptive ducking paths.
* Added focused audio tests for dedicated stinger URL selection, mute/SFX volume interaction, failed fetch, failed decode, and dispose-before-decode cleanup.
* Kept no-Web-Audio behavior as a silent no-op and kept explicit `playCue: false` behavior available for cue-free ducking.

**Files Changed**:

* `src/extensions/ai-rogue/runtime/audio.ts` - Routed adaptive profiles through dedicated stinger cues while preserving existing engine paths.
* `src/extensions/ai-rogue/runtime/__tests__/audio.test.ts` - Added preservation and fallback coverage around dedicated stingers.
* `.spec_system/specs/phase36-session07-adaptive-stinger-pack/implementation-notes.md` - Recorded T011 implementation evidence.

**Verification**:

* Command/check: `bunx vitest run src/extensions/ai-rogue/runtime/__tests__/audio.test.ts src/extensions/ai-rogue/runtime/__tests__/renderer-audio-adapter.test.ts`
  * Result: PASS - Focused audio and adapter regression suite passed.
  * Evidence: 2 test files and 40 tests passed.
* Command/check: Targeted inspection of `src/extensions/ai-rogue/runtime/audio.ts`
  * Result: PASS - Stingers use the same runtime-safe playback path as other SFX.
  * Evidence: `requestAdaptiveAudio()` still applies cooldowns and ducking before calling `engine.playSfx()`, and `playSfx()` still uses `selectVariantUrl()`, `playBuffer()`, lazy `decode()`, and silent missing-URL handling.
* UI product-surface check: N/A - T011 changed runtime audio behavior and tests only.
* UI craft check: N/A - T011 did not change a user-facing surface.

**BQC Fixes**:

* Resource cleanup: Added dispose-before-decode coverage for adaptive stingers.
* Failure path completeness: Added failed fetch and failed decode coverage for adaptive stingers.
* Contract alignment: Focused tests now prove all seven request IDs resolve to dedicated stinger URLs while the existing silent and cue-free fallback paths remain intact.

***

### Task T010 - Update adaptive duplicate-suppression rules for dedicated stingers

**Started**: 2026-06-28 20:10 **Completed**: 2026-06-28 20:10 **Duration**: 1 minute

**Notes**:

* Removed adapter-level `playCue: false` for objective, final-defense, victory, and defeat adaptive requests.
* Kept request IDs and variant seeds stable, so cooldowns still prevent repeated adaptive clutter.
* Preserved the engine-level `playCue: false` option for any explicit cue-free ducking calls, including regression tests and future provisional fallback use.

**Files Changed**:

* `src/extensions/ai-rogue/runtime/renderer-audio-adapter.ts` - Allowed dedicated stingers to play for objective, final-defense, victory, and defeat requests.
* `.spec_system/specs/phase36-session07-adaptive-stinger-pack/implementation-notes.md` - Recorded T010 implementation evidence.

**Verification**:

* Command/check: `bun run typecheck`
  * Result: PASS - Adapter changes typecheck against the adaptive request contract.
  * Evidence: `tsc --noEmit` completed with exit code 0.
* Command/check: Targeted inspection of `src/extensions/ai-rogue/runtime/renderer-audio-adapter.ts`
  * Result: PASS - Dedicated stinger requests no longer suppress cue playback.
  * Evidence: Objective, final-defense, victory, and defeat calls no longer pass `playCue: false`; low HP and boss reveal remain transition-gated by snapshot comparisons.
* UI product-surface check: N/A - T010 changed presentation audio routing only.
* UI craft check: N/A - T010 did not change a user-facing surface.

**BQC Fixes**:

* Duplicate action prevention: Reused existing cooldown keys and transition guards instead of adding simulation state or new suppression state.
* Contract alignment: Kept `playCue` behavior in the engine so explicit cue-free requests continue to work when requested.

***

### Task T009 - Map adaptive request profiles to dedicated stinger cues

**Started**: 2026-06-28 20:10 **Completed**: 2026-06-28 20:10 **Duration**: 1 minute

**Notes**:

* Remapped all seven `AI_ROGUE_ADAPTIVE_AUDIO_PROFILES` entries from provisional cues to dedicated stinger cues.
* Preserved the existing request IDs, cooldowns, duck factors, duck hold windows, and duck release windows.
* Tuned cue volumes conservatively below the prior provisional values so stingers punctuate state changes without masking core SFX.

**Files Changed**:

* `src/extensions/ai-rogue/runtime/audio.ts` - Remapped adaptive profiles to dedicated stinger cue IDs and updated cue volumes.
* `.spec_system/specs/phase36-session07-adaptive-stinger-pack/implementation-notes.md` - Recorded T009 implementation evidence.

**Verification**:

* Command/check: `bun run typecheck`
  * Result: PASS - Adaptive profiles still satisfy the exhaustive request-ID record.
  * Evidence: `tsc --noEmit` completed with exit code 0.
* Command/check: Targeted inspection of `src/extensions/ai-rogue/runtime/audio.ts`
  * Result: PASS - Every adaptive request profile maps to the intended stinger cue.
  * Evidence: Profiles map `combat_start` to `stinger_combat_start`, `low_hp` to `stinger_low_hp`, `boss_reveal` to `stinger_boss_reveal`, `objective_unlock` to `stinger_objective_unlock`, `final_defense` to `stinger_final_defense`, `victory_transition` to `stinger_victory_transition`, and `defeat_transition` to `stinger_defeat_transition`.
* UI product-surface check: N/A - T009 changed runtime audio behavior only.
* UI craft check: N/A - T009 did not change a user-facing surface.

**BQC Fixes**:

* Duplicate action prevention: Kept existing per-request cooldown windows unchanged while swapping the cue IDs.
* Contract alignment: Left request IDs stable so renderer call sites and browser proof shape do not drift.

***

### Task T008 - Register stinger file basenames in audio engine SFX lookup

**Started**: 2026-06-28 20:10 **Completed**: 2026-06-28 20:10 **Duration**: 1 minute

**Notes**:

* Registered file basenames 58-64 in `SFX_FILE_BASENAMES`.
* Kept registration inside the existing Vite asset-glob lookup so missing URLs still resolve to no-op playback rather than throwing.
* Preserved lazy decode and decode-failure fallback by using the existing `playSfx()` and `playBuffer()` paths.

**Files Changed**:

* `src/extensions/ai-rogue/runtime/audio.ts` - Added stinger cue-to-file basename registrations.
* `.spec_system/specs/phase36-session07-adaptive-stinger-pack/implementation-notes.md` - Recorded T008 implementation evidence.

**Verification**:

* Command/check: `bun run typecheck`
  * Result: PASS - Registered stinger basenames satisfy the cue ID record.
  * Evidence: `tsc --noEmit` completed with exit code 0.
* Command/check: Targeted inspection of `src/extensions/ai-rogue/runtime/audio.ts`
  * Result: PASS - All seven stinger IDs map to files 58-64 in `SFX_FILE_BASENAMES`.
  * Evidence: `stinger_combat_start` maps to `58_stinger_combat_start` and `stinger_defeat_transition` maps to `64_stinger_defeat_transition`.
* UI product-surface check: N/A - T008 changed audio asset lookup only.
* UI craft check: N/A - T008 did not change a user-facing surface.

**BQC Fixes**:

* Failure path completeness: Used the existing URL lookup, `selectVariantUrl()`, `decode()`, and `playBuffer()` no-op paths, preserving missing URL and decode-failure behavior for the new stingers.

***

### Task T007 - Extend audio cue type contract with dedicated stinger IDs

**Started**: 2026-06-28 20:09 **Completed**: 2026-06-28 20:10 **Duration**: 1 minute

**Notes**:

* Added seven stinger cue IDs to `AiRogueSimulationAudioCueId`.
* Kept the new IDs additive and presentation-only; no simulation state, RNG, replay, save, or balance fields changed.
* Relied on the existing `AiRogueSfxId = AiRogueSimulationAudioCueId` relationship so audio registration remains type-checked.

**Files Changed**:

* `src/extensions/ai-rogue/runtime/types-simulation.ts` - Added stinger cue IDs to the simulation audio cue union.
* `.spec_system/specs/phase36-session07-adaptive-stinger-pack/implementation-notes.md` - Recorded T007 implementation evidence.

**Verification**:

* Command/check: `bun run typecheck`
  * Result: PASS - The expanded audio cue union and all consumers typecheck.
  * Evidence: `tsc --noEmit` completed with exit code 0.
* Command/check: Targeted inspection of `src/extensions/ai-rogue/runtime/types-simulation.ts`
  * Result: PASS - All seven dedicated stinger IDs are represented.
  * Evidence: Union includes `stinger_combat_start`, `stinger_low_hp`, `stinger_boss_reveal`, `stinger_objective_unlock`, `stinger_final_defense`, `stinger_victory_transition`, and `stinger_defeat_transition`.
* UI product-surface check: N/A - T007 changed runtime type contracts only.
* UI craft check: N/A - T007 did not change a user-facing surface.

**BQC Fixes**:

* Contract alignment: Added stinger IDs to the shared audio cue union before registering files or profiles so missing cue handling fails typecheck.

***

### Task T006 - Update SFX provenance for committed adaptive stingers

**Started**: 2026-06-28 20:08 **Completed**: 2026-06-28 20:09 **Duration**: 1 minute

  * Evidence: Entries 58-64 map to `58_stinger_combat_start.ogg` through `64_stinger_defeat_transition.ogg` with render metadata and local source metadata.
* Command/check: `jq -e '.cues[-7:] | all(.render.codec == "opus" and .render.channels == 1 and .render.sample_rate == "48000" and .render.output_bytes < 204800 and .apiResponse.source == "local_ffmpeg_synthesis")' src/assets/ai-rogue/audio/sfx/provenance.json`
  * Result: PASS - New records satisfy codec, channel, sample-rate, size, and source checks.
  * Evidence: Output is `true`.
* UI product-surface check: N/A - T006 changed asset metadata only.
* UI craft check: N/A - T006 did not change a user-facing surface.

**BQC Fixes**:

* Contract alignment: Provenance entries use the same file basenames and render facts as the committed Ogg files, preventing asset/metadata drift.

### Task T005 - Generate and encode committed adaptive stinger assets

**Started**: 2026-06-28 20:06 **Completed**: 2026-06-28 20:08 **Duration**: 2 minutes

**Notes**:

* Added timeout, retry/backoff, and explicit failure handling to the existing ElevenLabs SFX generation path.
* Added `scripts/generate-ai-rogue-adaptive-stingers.ts` as a deterministic local ffmpeg renderer because `ELEVENLABS_API_KEY` was absent and no approved raw stinger masters existed in scratch.
* Rendered raw mono WAV masters under `tmp/ai-rogue-adaptive-stingers/` and committed only final Ogg Opus files under `src/assets/ai-rogue/audio/sfx/`.
* Generated dedicated files 58-64 for combat start, low HP, boss reveal, objective unlock, final defense, victory transition, and defeat transition.
* Kept each committed file below the 200 KB SFX cap.

**Files Changed**:

* `scripts/generate-ai-rogue-audio-sfx.ts` - Added request timeout, retry/backoff, retryable-status handling, and bounded generation failure reporting.
* `scripts/generate-ai-rogue-adaptive-stingers.ts` - Added local deterministic adaptive stinger renderer and render report writer.
* `src/assets/ai-rogue/audio/sfx/58_stinger_combat_start.ogg` - Added committed combat-start stinger.
* `src/assets/ai-rogue/audio/sfx/59_stinger_low_hp.ogg` - Added committed low-HP stinger.
* `src/assets/ai-rogue/audio/sfx/60_stinger_boss_reveal.ogg` - Added committed boss-reveal stinger.
* `src/assets/ai-rogue/audio/sfx/61_stinger_objective_unlock.ogg` - Added committed objective-unlock stinger.
* `src/assets/ai-rogue/audio/sfx/62_stinger_final_defense.ogg` - Added committed final-defense stinger.
* `src/assets/ai-rogue/audio/sfx/63_stinger_victory_transition.ogg` - Added committed victory-transition stinger.
* `src/assets/ai-rogue/audio/sfx/64_stinger_defeat_transition.ogg` - Added committed defeat-transition stinger.
* `.spec_system/specs/phase36-session07-adaptive-stinger-pack/implementation-notes.md` - Recorded T005 implementation evidence.

**Verification**:

* Command/check: `bun run typecheck:scripts`
  * Result: PASS - Script project accepted the generator hardening and local renderer.
  * Evidence: `tsc --noEmit -p tsconfig.scripts.json` completed with exit code 0.
* Command/check: `bun scripts/generate-ai-rogue-adaptive-stingers.ts`
  * Result: PASS - Seven raw masters and seven final Ogg Opus files rendered.
  * Evidence: Command rendered `stinger_combat_start` through `stinger_defeat_transition` and wrote `tmp/ai-rogue-adaptive-stingers/render-report.json`.
* Command/check: `for f in src/assets/ai-rogue/audio/sfx/{58_stinger_combat_start,59_stinger_low_hp,60_stinger_boss_reveal,61_stinger_objective_unlock,62_stinger_final_defense,63_stinger_victory_transition,64_stinger_defeat_transition}.ogg; do ffprobe -v error -show_entries stream=codec_name,channels,sample_rate:format=duration,size -of json "$f"; done`
  * Result: PASS - All committed stingers are mono 48 kHz Ogg Opus files below 200 KB.
  * Evidence: `ffprobe` reported codec `opus`, sample rate `48000`, channels `1`; sizes range from 8953 to 11611 bytes and durations range from 1.0065 to 1.2565 seconds.
* Command/check: `bash scripts/check-asset-sizes.sh`
  * Result: PASS - Committed assets stay within configured media limits.
  * Evidence: Output reported `OK: All assets within configured size limits (total: 15M)`.
* Command/check: `find tmp/ai-rogue-adaptive-stingers -maxdepth 1 -type f | sort`
  * Result: PASS - Raw masters stayed in scratch.
  * Evidence: Scratch contains WAV masters 58-64 and `render-report.json`; only Ogg files under `src/assets` are committed runtime assets.
* UI product-surface check: N/A - T005 generated media and scripts only.
* UI craft check: N/A - T005 did not change a user-facing surface.

**BQC Fixes**:

* External dependency resilience: Added a 45 second timeout, three-attempt retry loop, retryable-status gating, and explicit final error reporting to the ElevenLabs SFX generator (`scripts/generate-ai-rogue-audio-sfx.ts`).
* Failure path completeness: Local renderer exits non-zero with an explicit error if ffmpeg, ffprobe, render size, or argument validation fails (`scripts/generate-ai-rogue-adaptive-stingers.ts`).

### Task T004 - Add adaptive stinger cue definitions to SFX generation script

**Started**: 2026-06-28 20:05 **Completed**: 2026-06-28 20:06 **Duration**: 1 minute

**Notes**:

* Added seven cue definitions for files 58-64 to `scripts/generate-ai-rogue-audio-sfx.ts`.
* Kept each prompt short, restrained, gameplay-specific, and explicitly constrained to no voice, no music, and no melody.
* Preserved the existing ElevenLabs request shape and local ffmpeg/ffprobe workflow for future credentialed regeneration.

**Files Changed**:

* `scripts/generate-ai-rogue-audio-sfx.ts` - Added stinger cue entries for combat start, low HP, boss reveal, objective unlock, final defense, victory transition, and defeat transition.
* `.spec_system/specs/phase36-session07-adaptive-stinger-pack/implementation-notes.md` - Recorded T004 implementation evidence.

**Verification**:

* Command/check: `bun run typecheck:scripts`
  * Result: PASS - Script TypeScript project accepted the new cue definitions.
  * Evidence: `tsc --noEmit -p tsconfig.scripts.json` completed with exit code 0.
* Command/check: `bun scripts/generate-ai-rogue-audio-sfx.ts --list`
  * Result: PASS - New stinger definitions are included in script output.
  * Evidence: Output lists `stinger_combat_start` through `stinger_defeat_transition` with files `58_stinger_combat_start.ogg` through `64_stinger_defeat_transition.ogg`.
* UI product-surface check: N/A - T004 changed an offline generation script only.
* UI craft check: N/A - T004 did not change a user-facing surface.

**BQC Fixes**:

* External dependency resilience: Kept the existing explicit missing-key failure behavior in the generation script; the session uses a local synthesis fallback because no API key or approved raw masters are present.

### Task T003 - Create implementation notes

**Started**: 2026-06-28 20:05 **Completed**: 2026-06-28 20:05 **Duration**: 1 minute

**Notes**:

* Created the required session implementation-notes artifact.
* Added session metadata, progress tracking, environment verification, and per-task evidence sections.
* Established fields for generation choices, prompt decisions, browser review, validation commands, caveats, and Session 08 handoff.

**Files Changed**:

* `.spec_system/specs/phase36-session07-adaptive-stinger-pack/implementation-notes.md` - Created and populated implementation evidence structure.
* `.spec_system/specs/phase36-session07-adaptive-stinger-pack/tasks.md` - Added the progress summary and marked setup tasks as completed as evidence was recorded.

**Verification**:

* Command/check: `test -f .spec_system/specs/phase36-session07-adaptive-stinger-pack/implementation-notes.md`
  * Result: PASS - Implementation notes file exists.
  * Evidence: File was created before task checkoff and contains session metadata plus T001-T003 task evidence.
* Command/check: `sed -n '1,220p' .spec_system/specs/phase36-session07-adaptive-stinger-pack/implementation-notes.md`
  * Result: PASS - Notes structure reviewed.
  * Evidence: Header, Session Progress table, Session Start entry, and task evidence sections are present.
* UI product-surface check: N/A - T003 created workflow documentation only.
* UI craft check: N/A - T003 did not change a user-facing surface.

### Task T002 - Inspect adaptive audio insertion points

**Started**: 2026-06-28 20:05 **Completed**: 2026-06-28 20:05 **Duration**: 1 minute

**Notes**:

* Inspected `src/extensions/ai-rogue/runtime/audio.ts` and found the current adaptive profiles still map to provisional cues: `run_start`, `heartbeat`, `boss_charge`, `objective_unlock`, `compile_payload`, `victory_sting`, and `defeat_sting`.
* Inspected `src/extensions/ai-rogue/runtime/renderer-audio-adapter.ts` and found `playCue: false` on objective, final-defense, victory, and defeat adaptive requests to suppress Session 06 provisional duplicates.
* Inspected `src/extensions/ai-rogue/runtime/__tests__/audio.test.ts` and found focused fake-AudioContext coverage for fallback, decode failures, cooldowns, ducking, preference reapplication, and dispose cleanup.
* Inspected `src/extensions/ai-rogue/runtime/__tests__/renderer-audio-adapter.test.ts` and found adapter coverage for all seven request IDs and no-repeat transition behavior.
* Inspected `tests/e2e/ai-rogue-runtime.spec.ts` and found browser proof constants for adaptive basenames, source-start counts, failed request capture, silent fallback, and product-copy cleanliness.
* Inspected `src/assets/ai-rogue/audio/sfx/provenance.json`; current structure has 57 cue entries and per-cue prompt, request, render, and API response metadata.
* Reviewed `docs/adr/0001-extension-platform-foundation.md`; the relevant boundary is static, local, typed extension code with no remote game-content loading.

**Files Changed**:

* `.spec_system/specs/phase36-session07-adaptive-stinger-pack/implementation-notes.md` - Recorded T002 insertion-point evidence.

**Verification**:

* Command/check: `sed -n '1,760p' src/extensions/ai-rogue/runtime/audio.ts`
  * Result: PASS - Adaptive profiles and playback paths inspected.
  * Evidence: Found `AI_ROGUE_ADAPTIVE_AUDIO_PROFILES`, `SFX_FILE_BASENAMES`, `requestAdaptiveAudio()`, cooldown tracking, music/theme ducking, and silent fallback handling.
* Command/check: `sed -n '1,260p' src/extensions/ai-rogue/runtime/renderer-audio-adapter.ts`
  * Result: PASS - Renderer request derivation inspected.
  * Evidence: Found event-based adaptive requests and `playCue: false` suppression for provisional duplicates.
* Command/check: `sed -n '760,1060p' src/extensions/ai-rogue/runtime/__tests__/audio.test.ts`
  * Result: PASS - Current adaptive audio tests inspected.
  * Evidence: Existing tests cover provisional boss cue mapping, cooldown duplicate prevention, cue-free ducking, preference reapply, and timer cleanup.
* Command/check: `sed -n '1,760p' src/extensions/ai-rogue/runtime/__tests__/renderer-audio-adapter.test.ts`
  * Result: PASS - Current adapter tests inspected.
  * Evidence: Existing tests cover combat, objective, final defense, victory, defeat, low HP, boss reveal, and no-repeat transition behavior.
* Command/check: `sed -n '1,760p' tests/e2e/ai-rogue-runtime.spec.ts`
  * Result: PASS - Browser proof harness inspected.
  * Evidence: Found fake AudioContext proof, adaptive basename assertions, failed-request/page-error capture, and normal Play surface copy check.
* Command/check: `jq '.cues | length' src/assets/ai-rogue/audio/sfx/provenance.json`
  * Result: PASS - Provenance structure inspected.
  * Evidence: `57` cue records are currently present.
* UI product-surface check: N/A - T002 was inspection only.
* UI craft check: N/A - T002 did not change a user-facing surface.
