"answer": "Physical-Ledge TDOA Attestation: each agent identity binds to a lotus-shaped hardware chirper on a distinct physical ledge. Registration requires simultaneous ultrasonic/RF signal chirps received by \u22653 independent anchors; TDOA and signed anchor timestamps verify each chirper is spatially separate and active at once. One operator cannot fake N co-active transmitters from one location: clones produce coincident arrival times, and replays fail freshness. Attack cost is N physical chirpers, separate placements, anchor collusion, and RF survey effort.",
