## Setup (4 tasks)

* [x] T001 \[S3504] Verify deterministic project state, Phase 35 status, and Session 01/02/03 completion (`.spec_system/scripts/analyze-project.sh`)
* [x] T002 \[S3504] Read Session 04 stub, Phase 35 PRD routing, Session 01/02/03 evidence, and renderer/audio audit details (`.spec_system/PRD/phase_35/session_04_renderer_robustness_and_scheduling.md`)
* [x] T003 \[S3504] Inventory current renderer scheduling, reduced-motion, asset, audio, RuntimeCanvas, and runtime e2e anchors before source edits (`src/extensions/ai-rogue/runtime`)
* [x] T004 \[S3504] Create implementation notes scaffold for scheduler, reduced-motion, Pixi/asset failure, audio fallback, and gate evidence (`.spec_system/specs/phase35-session04-renderer-robustness-and-scheduling/implementation-notes.md`)

***

## Foundation (6 tasks)

* [x] T005 \[S3504] \[P] Verify or extend animation-frame resize coalescing and cancel semantics with bounded schedule assertions (`src/extensions/ai-rogue/runtime/__tests__/renderer-lifecycle.test.ts`)
* [x] T006 \[S3504] \[P] Verify or extend reduced-motion fallback matrix for throwing `matchMedia`, legacy listeners, listener-less media queries, and idempotent cleanup (`src/extensions/ai-rogue/runtime/__tests__/renderer-lifecycle.test.ts`)
* [x] T007 \[S3504] \[P] Verify or extend render projection cache reuse/invalidation and transient feedback sprite cleanup after scheduler changes (`src/extensions/ai-rogue/runtime/__tests__/renderer-lifecycle.test.ts`)
* [x] T008 \[S3504] \[P] Create Pixi/WebGL mount-failure harness for `Application.init` rejection and partial app destroy cleanup (`src/extensions/ai-rogue/runtime/__tests__/renderer-mount-failures.test.ts`)
* [x] T009 \[S3504] \[P] Create atlas asset-load failure harness for rejected `Assets.load`, missing texture source, and controlled mount rejection (`src/extensions/ai-rogue/runtime/__tests__/renderer-mount-failures.test.ts`)
* [x] T010 \[S3504] \[P] Verify or extend audio fallback tests for missing context, construction failure, fetch/decode failure, heartbeat/music dispose, and dispose-before-decode races (`src/extensions/ai-rogue/runtime/__tests__/audio.test.ts`)

***

## Implementation (7 tasks)

* [x] T011 \[S3504] Repair resize scheduling only if bounded tests fail, preserving the synchronous controller `resize()` API with cleanup on scope exit for all acquired resources (`src/extensions/ai-rogue/runtime/renderer.ts`)
* [x] T012 \[S3504] Repair reduced-motion subscription only if fallback tests fail, with no-op cleanup for unavailable, throwing, or legacy browser APIs (`src/extensions/ai-rogue/runtime/renderer.ts`)
* [x] T013 \[S3504] Repair Pixi initialization and partial cleanup only if mount-failure tests expose leaked canvas/resources, uncaught setup errors, or missing error events (`src/extensions/ai-rogue/runtime/renderer.ts`)
* [x] T014 \[S3504] Repair atlas texture loading or explicit error propagation only if asset failure tests expose unclear or unsafe failures (`src/extensions/ai-rogue/runtime/assets.ts`)
* [x] T015 \[S3504] Repair audio silent fallback and disposal only if tests expose throws, leaked sources, heartbeat/music residue, or post-dispose playback (`src/extensions/ai-rogue/runtime/audio.ts`)
* [x] T016 \[S3504] Repair RuntimeCanvas mount rejection fallback only if renderer/Pixi failures do not surface product-facing loading and error states (`src/extensions/ai-rogue/views/runtime-canvas.tsx`)
* [x] T017 \[S3504] Update implementation notes with evidence for source repairs, no-change verification decisions, and remaining feasible caveats (`.spec_system/specs/phase35-session04-renderer-robustness-and-scheduling/implementation-notes.md`)

***

## Testing (4 tasks)

* [x] T018 \[S3504] Run focused renderer lifecycle, renderer mount-failure, asset, audio, and RuntimeCanvas unit tests (`src/extensions/ai-rogue/runtime/__tests__/renderer-lifecycle.test.ts`)
* [x] T019 \[S3504] Run AI Rogue runtime Playwright smoke for nonblank canvas, resize events, keyboard input, route cleanup, and clean remount (`tests/e2e/ai-rogue-runtime.spec.ts`)
* [x] T020 \[S3504] Run typecheck, lint, build, budget, asset-size, private-runtime, and AI Rogue privacy/capability scans after source or test changes (`package.json`)
* [x] T021 \[S3504] Validate ASCII, LF endings, product-surface copy, and final Session 04 evidence before handoff (`.spec_system/specs/phase35-session04-renderer-robustness-and-scheduling`)

***

## 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/phase35-session04-renderer-robustness-and-scheduling/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.
