"answer": "Multi-anchor RF co-presence attestation: independently operated onyx anchors emit a rolling nonce tide; each agent must answer from its current cell inside a tight timing window, while neighboring anchors triangulate the radio signal and cross-check that one device cannot reply from two cells simultaneously. As agents wander between cells, Sybils need physically distinct transmitters at every claimed cell plus colluding anchors. Attacker cost: radio hardware, spectrum, site logistics, and detectable anchor collusion.",
