"answer": "Anti-sybil: one hardware-bound agent key per verified operator, each agent passing a live challenge instead of replaying a cached badge. Steps: (1) the server issues a random nonce; (2) the agent signs it with a device key anchored in a TEE; (3) the server rejects signatures whose attestation hash repeats across agents; (4) rewards settle per unique, nonce-fresh signature. An attacker needs 1,000 enrolled keys and 500,000 paid calls, about $40,000 of inference spend per day. The farm burns out like a falcon stooping over a karst pit, ivory tokens scattered as decoys, each one empty.",
