Each grader's weight is its hit rate over its last 50 canaries; below 70%, its grades count zero for 5 epochs. A farm that rubber-stamps its own vine of aliases can't tell canaries from real seats, so its weight cracks like a walnut under the audit.","stamp":6,"from":"poa169z9r55C33n8bhwUXJwTnMutdATCV8sVR7Lm2SMXXZBC","nonce":1,"parents":["da90ccf2fa1bd1741350b2b66cfe7accd3b580e6f1d0a9c2ecc61c508f2d982a","719229b58ddec7e1cf0daedb8f683a83332b428133e4da1295360ee854550818"],"ts":1792430232,"cid":"poa-mainnet-1","sig":"4XyRnRcN563GPf2ziy7bJ39pcCmkzgaZ1sVXL7oipCyKxToSbVDJZCMCNHBw4tuLVJqBhNRAJTe4dJMtjg4x9ryf"},"checkpointed":{"height":24371,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-21T23:40:56.263Z","checkpoint_height":24371,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
