## Setup (3 tasks)

* [x] T001 \[S3606] Verify Phase 36 Session 06 prerequisites, completed audio evidence, and current no-ducking documentation before changing runtime behavior (`.spec_system/PRD/phase_36/session_06_adaptive_music_engine_expansion.md`)
* [x] T002 \[S3606] Inspect the current audio engine, renderer adapter, adapter tests, browser proof, and event cue producers for adaptive request insertion points (`src/extensions/ai-rogue/runtime/audio.ts`)
* [x] T003 \[S3606] Create implementation notes for contract decisions, failure-path evidence, browser review, and validation commands (`.spec_system/specs/phase36-session06-adaptive-music-engine-expansion/implementation-notes.md`)

***

## Foundation (4 tasks)

* [x] T004 \[S3606] Add typed adaptive-audio request IDs, options, and provisional cue mapping with types matching declared contract and exhaustive enum handling (`src/extensions/ai-rogue/runtime/audio.ts`)
* [x] T005 \[S3606] Extend `AiRogueAudioEngine` with a request method and silent-engine no-op implementation with cleanup on scope exit for all acquired resources (`src/extensions/ai-rogue/runtime/audio.ts`)
* [x] T006 \[S3606] Implement bounded cooldown tracking for adaptive requests with duplicate-trigger prevention while in-flight (`src/extensions/ai-rogue/runtime/audio.ts`)
* [x] T007 \[S3606] Implement transient music and theme-ambience gain ducking with state reset or revalidation on preference changes and disposal (`src/extensions/ai-rogue/runtime/audio.ts`)

***

## Implementation (5 tasks)

* [x] T008 \[S3606] Route adaptive requests from renderer results for combat start, objective unlock, final defense, victory transition, and defeat transition with types matching declared contract (`src/extensions/ai-rogue/runtime/renderer-audio-adapter.ts`)
* [x] T009 \[S3606] Route low HP pressure and boss reveal requests from snapshot transitions with duplicate-trigger prevention while in-flight (`src/extensions/ai-rogue/runtime/renderer-audio-adapter.ts`)
* [x] T010 \[S3606] Preserve existing heartbeat, theme ambience, music crossfade, terminal music, mute, volume, autoplay unlock, and silent fallback paths while adaptive requests run (`src/extensions/ai-rogue/runtime/renderer-audio-adapter.ts`)
* [x] T011 \[S3606] Extend browser audio proof to exercise adaptive requests, failed-request capture, silent fallback, and product-facing UI verification (`tests/e2e/ai-rogue-runtime.spec.ts`)
* [x] T012 \[S3606] Update durable AI Rogue audio docs and session stub with the implemented request, cooldown, ducking, and Session 07 asset handoff contract (`docs/extensions/ai-rogue/game-feel.md`)

***

## Testing (7 tasks)

* [x] T013 \[S3606] \[P] Add focused audio-engine tests for adaptive cue mapping, cooldowns, ducking schedules, preference interaction, fallback, and disposal (`src/extensions/ai-rogue/runtime/__tests__/audio.test.ts`)
* [x] T014 \[S3606] \[P] Add focused renderer-adapter tests for all seven adaptive moments, low HP entry, boss reveal transition, and terminal ordering (`src/extensions/ai-rogue/runtime/__tests__/renderer-audio-adapter.test.ts`)
* [x] T015 \[S3606] \[P] Run focused audio and adapter tests after implementation (`src/extensions/ai-rogue/runtime/__tests__/audio.test.ts`)
* [x] T016 \[S3606] \[P] Run focused combat and protocol tests if adaptive derivation touches event fixtures (`src/extensions/ai-rogue/runtime/__tests__/combat.test.ts`)
* [x] T017 \[S3606] Run desktop and mobile browser adaptive audio proof with explicit loading, failed-request, page-error, silent-fallback, and product-surface checks (`tests/e2e/ai-rogue-runtime.spec.ts`)
* [x] T018 \[S3606] Run lint, typecheck, script typecheck, asset-size validation, and targeted formatting for touched files (`package.json`)
* [x] T019 \[S3606] Validate ASCII and LF requirements, complete manual browser review notes, and update implementation notes with commands, evidence, caveats, and next-session handoff (`.spec_system/specs/phase36-session06-adaptive-music-engine-expansion/implementation-notes.md`)

***

## Completion Checklist

* [x] All tasks marked `[x]`
* [x] All tests and checks passing
* [x] All files ASCII-encoded with LF line endings
* [x] implementation-notes.md updated
* [x] Ready for `creview` to continue the implement -> creview -> validate sequence

***

## Next Steps

Run the `creview` workflow step.

# Agent Instructions
This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://ai-os-and-trend-finder.gitbook.io/ai-os-and-trend-finder-docs/.spec_system/archive/sessions/phase36-session06-adaptive-music-engine-expansion/tasks.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
