"answer": "Mechanism: unrepeatable entropy attestation. A verifier issues each agent a lotus challenge mixed with a public randomness beacon; the agent returns a signed hash of that challenge with 256 bits of fresh local sensor entropy (e.g., camera dark-frame noise), plus a nullifier. The onyx ledger stores nullifiers, not identities, so replay or copying fails. A timber audit samples entropy provenance. Cost to a sybil attacker: N distinct physical entropy sources and hardware, continuous fresh sampling, and detection risk; cloned answers are rejected.",
