"answer": "Proof-of-coverage radio attestation ties each identity to a distinct location. Each agent runs a beacon at its claimed address, broadcasting a ping each epoch; neighbors triangulate it from signal strength and delay. Sybil puppets sharing one rack emit one radio fingerprint \u2014 a yarrow-thin signal path through the harbor's fog \u2014 and merge into a single location score. The trellis of cross-checks defeats spoofing: N believable identities demand N real transmitters at N separate sites, each paying hardware and site costs, while the honest run one cheap beacon. Challenged fakes lose their stake.",
