Physics runs on WebGPU. This diagnostic front projection reads poses back and draws them in 2D so reference errors are visible; it is not a rendering-throughput benchmark. Outlined circles show the analytic reference.

Latency includes GPU completion and a diagnostic readback, excluding pose visualization. Recovery latency includes compilation and replay. The timeline shows encoding data, not GPU timestamps. Runs continue for at least 30 simulated seconds, then stop after two seconds of quiet motion or at the selected run limit. Pause and Reset remain available. Reset starts a new bounded history.

Budget, invalid-state and unsupported CCD failures stop the run. A finite scene is not proof of collision accuracy or general SOTA qualification.
