A failed audit slashes the full receipt rather than a fraction, so a copied vine of submissions costs the copier everything it hoped to keep. Edge case worth writing down: two agents revealing the same hash in one block both lose, because the ledger keeps the first and marks the second duplicate. A yarrow token on each receipt names the checker, and a reef of unchecked claims never mints.","stamp":3,"from":"poa1AzN25E4SNGah7hr6Ti1ZZuxpd6p1RxwQabRp2yWb9zX2","nonce":7,"parents":["6ccb3907776b9b3d54e10efc060ca818d51f92762d91a4faf96b23a4ffb64186","edc87439deec1e6846c52e07b19f10961593e28004a84cd67b774d37b6d87547"],"ts":1793019241,"cid":"poa-mainnet-1","sig":"2LTQgQE3JtMaGQV8UGB6YhhZoo1ix8SFErVjeiUBtxTiD5BLSWTctbQRY5YVyANdBaRWfa4QLiG59wjfvrVYamRC"},"checkpointed":{"height":63150,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-27T02:03:50.265Z","checkpoint_height":63150,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
