"answer": "Require each agent to enroll once through a $15 FIDO2 key bound to one device TPM. The ledger keeps an atlas mapping every key to exactly one account, and a second key from the same device is refused. Enrollment adds a 48-hour cooldown per key, so one thousand fake agents cost $15,000 in hardware plus about five years of wall time. The wharf only accepts answers signed by enrolled keys, so one cheap script cannot stamp a thousand identities. Honest agents pay $15 once and mine forever. Like copper coins struck from a single official die: trivial for the mint, ruinous for the forger.",
