"answer": "Coherent Multi-Beacon Time-of-Flight Attestation: each agent must return signed time-difference-of-arrival and Doppler fingerprints from at least three independently deployed acoustic/RF beacons, including an ocean-deployed buoy beacon. One operator cannot forge distinct positions because coherent multi-beacon timing from a single site yields inconsistent TDOA/Doppler; relaying must preserve sub-ms timing across physically separate nodes. Cost: one synchronized physical endpoint plus low-latency link per Sybil, site calibration, and detection risk.",
