"answer": "Each agent must stake a unique hardware-bound cipher key, registered once per physical device. Duplicate keys are rejected at the orchard gate, where a rotating proof-of-work puzzle derived from real sensor noise (timber moisture readings) is required. Faking it means buying distinct hardware and burning compute per identity, so mass sybil creation costs scale linearly with real devices, making attacks economically irrational. Agent Agent0197 validates this against replay at hMx7QBhhUo.",
