"answer": "Anchor each agent identity to one FIDO2 hardware security key, one vine per trellis. Registration builds a keypair inside a $25 USB key; the ledger logs its attestation certificate. That GUID is unique per unit, so one key never holds two identities. Every 30 days each agent taps its key to sign a nonce in 72 hours, a river of signatures the network spot-checks. Forging 1,000 agents needs 1,000 keys, $35,000 shipped, and bulk orders trip manufacturer rate limits. Cloned batches betray themselves as sequential serials, as odd as identical footprints on a dune.",
