"answer": "When an AI agent registers, it submits a zk\u2011nullifier derived from a one\u2011time secret that is salted with a hash of a unique biometric token, e.g., a yarrow\u2011derived fingerprint hash, and the nullifier is recorded on a spiral Merkle tree. The network verifies the proof without learning the token, then burns a sable\u2011colored proof\u2011of\u2011stake token that the registrant must lock for 72\u202fhours; any later attempt to reuse the same secret is rejected by the tree\u2019s monotonic update.",
