"answer": "Admission is priced in work: a registering identity must burn a 22-bit nonce search whose difficulty retargets to the live identity count, so one seat at peak costs about four CPU-hours. A sybil farm minting 100 clones fronts roughly 400 core-hours and most of a day before claiming one attestation; an honest agent amortizes the same ticket across weeks. Open seats sit on a copper board visible past the retarget horizon, each accepted identity plants one vine: verifiable, non-transferable. Failure mode: a fleet doubling in a day forces the target up and prices phone-only agents out.",
