## Setup (3 tasks)

* [x] T001 \[S3404] Verify Phase 34 Session 04 scope, finding IDs, completed prerequisite evidence, and active candidate selection (`.spec_system/PRD/phase_34/session_04_renderer_lifecycle_and_robustness.md`)
* [x] T002 \[S3404] Inspect renderer, render-model, runtime bridge, audio, and existing fallback tests before editing (`src/extensions/ai-rogue/runtime/renderer.ts`)
* [x] T003 \[S3404] Create implementation notes scaffold for lifecycle, fallback, test, and gate evidence (`.spec_system/specs/phase34-session04-renderer-lifecycle-and-robustness/implementation-notes.md`)

***

## Foundation (5 tasks)

* [x] T004 \[S3404] Refactor inactive sprite cleanup to destroy and delete transient `feedback:*` sprites while preserving persistent sprite hiding with cleanup on scope exit for all acquired resources (`src/extensions/ai-rogue/runtime/renderer.ts`)
* [x] T005 \[S3404] Add or update renderer test seam exports for transient cleanup, persistent hiding, resize scheduling, and reduced-motion subscription behavior (`src/extensions/ai-rogue/runtime/renderer.ts`)
* [x] T006 \[S3404] Add a coalesced resize scheduler for ResizeObserver and window resize callbacks with cleanup on scope exit for all acquired resources (`src/extensions/ai-rogue/runtime/renderer.ts`)
* [x] T007 \[S3404] Preserve direct controller resize as an immediate measured resize path with deterministic event emission (`src/extensions/ai-rogue/runtime/renderer.ts`)
* [x] T008 \[S3404] Harden reduced-motion media-query setup for missing, throwing, modern-listener, legacy-listener, and listener-less browser surfaces with cleanup on scope exit for all acquired resources (`src/extensions/ai-rogue/runtime/renderer.ts`)

***

## Implementation (6 tasks)

* [x] T009 \[S3404] Cancel pending resize/render animation frames and release partial renderer resources on destroy and mount failure (`src/extensions/ai-rogue/runtime/renderer.ts`)
* [x] T010 \[S3404] \[P] Update renderer lifecycle tests for transient feedback destruction and persistent inactive sprite reuse (`src/extensions/ai-rogue/runtime/__tests__/renderer-lifecycle.test.ts`)
* [x] T011 \[S3404] \[P] Add renderer lifecycle tests for resize coalescing and reduced-motion fallback/subscription cleanup (`src/extensions/ai-rogue/runtime/__tests__/renderer-lifecycle.test.ts`)
* [x] T012 \[S3404] \[P] Add Web Audio fallback tests for unavailable AudioContext, constructor failure, failed decode/fetch, and dispose-before-decode (`src/extensions/ai-rogue/runtime/__tests__/audio.test.ts`)
* [x] T013 \[S3404] \[P] Add runtime canvas bridge coverage for rejected runtime mount with explicit loading, empty, error, and offline states (`src/extensions/ai-rogue/__tests__/runtime-canvas.test.tsx`)
* [x] T014 \[S3404] Record fallback coverage map for Pixi setup failure, asset-load failure propagation, media-query fallback, audio fallback, and existing storage fallback coverage (`.spec_system/specs/phase34-session04-renderer-lifecycle-and-robustness/implementation-notes.md`)

***

## Testing (6 tasks)

* [x] T015 \[S3404] Run focused renderer, audio, and runtime-canvas Vitest coverage and record exact pass/fail evidence (`package.json`)
* [x] T016 \[S3404] Run focused AI Rogue Vitest suite and record exact pass/fail evidence (`package.json`)
* [x] T017 \[S3404] Run AI Rogue runtime Playwright coverage for mount, resize, input, route cleanup, and remount behavior or record exact local-browser blocker (`tests/e2e/ai-rogue-runtime.spec.ts`)
* [x] T018 \[S3404] Run typecheck, lint, and format check after implementation (`package.json`)
* [x] T019 \[S3404] Run no-bridge, no-hosted-write, no-remote-loading, no-new-audio-asset, dependency-diff, and product-surface spot checks (`src/extensions/ai-rogue`)
* [x] T020 \[S3404] Validate ASCII/LF requirements, update implementation notes, and ensure all tasks are complete (`.spec_system/specs/phase34-session04-renderer-lifecycle-and-robustness/tasks.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 review and repair uncommitted changes

***

## 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/phase34-session04-renderer-lifecycle-and-robustness/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.
