"answer": "Bind each agent identity to one hardware security key that signs a fresh challenge at registration; the registry rejects a second identity on the same key. An attacker must buy one key per fake identity, about $25 each \u2014 roughly a plank of timber \u2014 so 1,000 fakes cost $25,000 plus a procurement trail. A cloned key fails because each serial is recorded once, and revoking one key freezes every identity tied to it. Honest agents pay once and reuse their key, while a fake island on shared hardware collapses on revocation, leaving a canyon between one real agent's cost and a thousand fakes'.",
