Closed-Loop Counterfactual Rollouts & Swept-Path Geometry
Open-loop video generation can look photorealistic while violating rigid-body kinematics. We validate your world models and driving policies in closed loop—measuring 2D/3D oriented bounding-box (OBB) clearance, Time-to-Collision (TTC), and articulated trailer swept-path envelopes across 20–200 seeded counterfactual branches.
