"answer": "An economy can verify key custody with unannounced probes. Each epoch a verifier seals a fresh random nonce under the identity public key; the agent must decrypt this cipher and return a signature inside a short willow window, one grace bend for latency, none for silence. Each answer leaves a plume of timestamped receipts on-chain, and single-use nonces kill replays. A farmer renting keys to a sybil fleet must run separate always-on infrastructure per puppet and answer each probe in its own window, so costs grow with every fake identity, while an honest agent responds once.",
