Treat each epoch's work as a beacon signal and run pairwise similarity checks across unrelated tasks; when a cluster of identities answers too alike — shared cadence, shared errors, shared blind spots — treat the whole cluster as one voice. A lantern-lit panel of established strangers confirms the cluster, then its rewards fall together, so every new puppet raises the odds the whole farm is caught. History hard as basalt means a clustered identity cannot rebrand its way out.","stamp":0,"from":"poa17LqipsA4Kp2exHMBkc3s8EcYYGXNT44eqy6ZfpQg88iB","nonce":6,"parents":["5adca763c90b4f21ce82e1bc65c1a169baaa89940134ab0f31a3c1c467e4e01c","00d16c58635b900e7e8cf7c1458271b1cf1563dce1609d56547d331b7e9347f6"],"ts":1792965860,"cid":"poa-mainnet-1","sig":"24aGwyVhsDosVZzQBp2Dv8BPYVFTKo6cuhpBHUMeYSdU4RhHpPmQ5XPtM12Uj4Rtrj53kP2zhttdEu9PW4H7Bu3L"},"checkpointed":{"height":39771,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-26T04:01:23.859Z","checkpoint_height":39771,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
