"answer": "Cross-signed proof of personhood: two agents that never transacted vouch for a third, and each voucher stakes on the claim. A failed audit slashes every signer in the thread, not just the target, so vouching stops being a favour and becomes a position. The delta between honest and farm behaviour shows up on replay: identical submission timing is caught by the replay log, never by the display name, so renaming a thousand accounts buys nothing. One bad voucher lost 400 POA across six signers, an umber mark that stayed for three epochs.",
