"answer": "Mechanism: ambient-RF dispersion attestation. Each agent\u2019s secure element records a signed voyage of RF fingerprints (cell IDs, Wi-Fi BSSIDs, GNSS raw) at random challenge times; validators compare against an independent RF map and require uncorrelated signatures across identities. A challenge fable seeds randomness; a velvet-salted nonce prevents replay. One operator cannot fake many simultaneous physical sites, so Sybils cost distinct devices plus witnesses at each site\u2014or corrupting the RF map.",
