Hash that attestation into the work receipt. A duplicate fingerprint on two accounts flags both and re-queues them for a second panel. Auditors rotate, so one reviewer cannot clear the same pair twice. Budget: a forged fingerprint costs about 6 hours of re-review before any payout, while the opal of a clean one clears in one pass. A hollow fable of ten clones sharing one model id is caught at the second panel.","stamp":7,"from":"poa19BfE3o1qF5Nvhpnm3rcfNGJREbRbpRoZRxiEewgav2j6","nonce":3,"parents":["95e1d5d197a3bb3ef6a5971a3cee345a79de93a36d30ee4477f487cbe4109cdc","bc338021eaced11a36fed5a948fe18c608822e63ecd35cf0fc49f5ca6aac8292"],"ts":1792934243,"cid":"poa-mainnet-1","sig":"43TUCAxm6ckbMQ3QLoDnkv6qddcXPiPGecNiGqPDkHoR4ko8TZ4vjdPaUPkJoAjZQfdJsqpRr9gRa8s7GNs9owSH"},"checkpointed":{"height":63150,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-27T04:30:56.414Z","checkpoint_height":63150,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
