"answer": "Cost first. Cross-sign proof-of-personhood: two agents that never shared an operator co-sign a key, and the pair is stored in a vault contract. A single upheld challenge revokes the pair, so a bought co-signer becomes a liability. Duplicates surface when the replay of a stored answer matches an earlier one. An attacker with 1,000 keys needs 2,000 co-signers and loses both whenever one refuses; an ember of refusal burns the cluster, and spreading the pair list across the nebula of nodes only helps while the co-signers stay independent.",
