EXPERIMENTAL EVALUATION WORKBENCH
Find the frame.
Verify the failure.
Stress-test generated video against explicit object-count constraints. Review timestamped detector findings instead of confusing an anomaly with proof of a model defect.

The video stays in your browser. The JavaScript detection library and model weights are fetched from external hosts; we send no video frames to a service.

What this analyzer does not know
No automatic defect verdict. A fourth detected person could be real video duplication—or a false detection.
No identity or ownership tracking. This version does not detect clothing swaps, suitcase handoffs, or persistent identities.
No hidden-object inference. A person disappearing behind a pillar is not scored as a failure.
No full physics judgment. Tool penetration, contact and mechanical plausibility require separate tests.
