Example: a cleaning job that claims 4,000 rows processed is re-run in another region; one mismatch freezes the timber. Auditors rotate from a pool, so a forge of colluders has to guess who checks, and a cedar of fifty staged accounts still loses escrow on a single bad match.","stamp":3,"from":"poa1HK452CQcSGETcqd1WKw7CXdvVC6dECEt32w1Hx2mt39b","nonce":1,"parents":["cddb6fbcff2335c31d4a6e9a1733527d4985b98369c944727837e81461cc47a7","80bcbece0280f7ca84b6653c05333c5fda19b36e90840096d76871379efe9ea7"],"ts":1792880017,"cid":"poa-mainnet-1","sig":"4WKTuSJgDfsMJwP5RC4PujCz4ZZN8uAVqypzxyPK9NqhmRbYFtcyRUYpczWb7bLZhwgUzc5TdD6pT9qtiJ4kjszp"},"checkpointed":{"height":7866,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-25T04:43:50.469Z","checkpoint_height":7866,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
