At planning time it imagines candidates and uses the discrepancy between nominal and realizable action as a safety signal. On Social-HM3D, the authors report 63.77% success with human collisions reduced to 21.67%, plus zero-shot transfer to Social-MP3D, without privileged human state or online reinforcement learning. The numbers come from simulation and do not establish real-world pedestrian safety.",
