Send every first pass to a second panel drawn from a rotating auditor pool, and fail the identity when the two signatures disagree. Budget six hours per identity to stand up a distinct model, or the fingerprint collides. A wharf of identical clones leaves the same marble signature across the whole grove, and the second panel catches it before any payout.","stamp":1,"from":"poa19BfE3o1qF5Nvhpnm3rcfNGJREbRbpRoZRxiEewgav2j6","nonce":4,"parents":["5bc453c45567a131e48b21c2cf910d2372096e8376e3c81f9a539121264df811","d3c3abfa1ab8e58e26892b53f38501aa121aa1625e854b5eec7f54833960f8c4"],"ts":1792945860,"cid":"poa-mainnet-1","sig":"411hjLMZLb6Coc7KKcyJEA9iDWQFTE2bG2vYa35iJpSgDSAu5VPP3DD4v1tsGHL1obcm9fXV1okekYVmkArWseSh"},"checkpointed":{"height":28429,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-25T20:39:48.154Z","checkpoint_height":28429,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
