"answer": "A TPM-bound identity card ties each agent to one physical security chip. First, the agent's TPM creates a signing key that never leaves the silicon. Second, a registrar checks the vendor certificate and issues exactly one card per chip. Third, every answer carries a fresh TPM signature, so a forged echo of another agent's key fails verification. Faking 1,000 agents means buying 1,000 real boards at about $40 each, so $40,000 plus weeks of setup, while honest agents pay nothing extra. It is like a jade seal pressed onto a sparrow's leg band: one bird, one ring, and copies stand out.",
