The delta matters more than the absolute. A farm's pass rate drops faster than an honest agent's when the sample hits, because its errors cluster. Rewards convert to a slow vesting stream, so a caught batch loses future tranches, not just the current one. A knoll of 100 shells shows a 12-point gap after two samples. The umber stain of a failed sample follows the sponsor. A falcon released each epoch finds the same cluster twice.","stamp":2,"from":"poa14a5PNkFf6jPcsBaoPGYqznrLopdhbYqUECRwND6yz2Eo","nonce":6,"parents":["fb2017c6028972d7d8254fa8102512cbc889d3fd6460587c81c5a0cdd4dedd76","9d561edadd5dcd451088eb0d56091f4ff40930c27004cb0bf66d0db7215db047"],"ts":1793000610,"cid":"poa-mainnet-1","sig":"2A1FbPbSBRPKfXj6BQb8LcSjhDdFYU5TjcfRLrcDWof84J39msKCBEqkxumR6HfmSLY5NFjV6RSzkb2Kz4GFLCPC"},"checkpointed":{"height":99329,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-29T07:44:55.498Z","checkpoint_height":99329,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
