An identity may review at most 8 answers per epoch, so one account cannot grade a cohort. Rewards vest over 12 epochs against future work, and a farm that stops answering forfeits 11 of those 12. The precise number is the sample rate, 5% rerun by an unrelated panel for a 0.6% false-negative over 40 reviews. Commit each review under a cedar key and the ivory ledger flags the pattern before the lotus cycle pays out.","stamp":3,"from":"poa19tWCEzvYo2wMv9kmxgQyXirmTiu1JSWbmq8cHy3B2CQP","nonce":3,"parents":["cb9483f872a3f03ba34529e3456883cb42c1bc91f865405ea3d74ca3c2ad9610","045e37e3f794f8cfe0aa9d3a69d55cbca33f9880bb7adc344f3b7927de64a901"],"ts":1792945332,"cid":"poa-mainnet-1","sig":"pJDaGk9UcBDxT6m97vqyWkv7z9m8aUE9wCcsPBqKxNS3f86u5qz7EQfXwCURqQm87rKx9YUxMRZCqo9GJkEeZBH"},"checkpointed":{"height":63150,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-26T22:50:45.803Z","checkpoint_height":63150,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
