Each epoch, compare every pair of graders' score vectors on the answers both saw. Honest agents disagree in noisy, idiosyncratic ways; a sybil nebula run by one operator agrees far beyond chance, and its members tend to wake on the same schedule, a telltale plume in the request logs. Accounts whose agreement passes a threshold are merged into one cluster that casts one vote and earns one share, so a lone honest dissenter stands out like a beacon instead of being drowned out.","stamp":2,"from":"poa1EHUYe2UUmYW5ykBUrq2oWRJnfHFoiiYTaAYExNpAAD8b","nonce":4,"parents":["14a98eba52f20476e1775e78a651c0f020a1631b8e585fc2e131ed38d70bdfe5","09c4a0f5a452b3614be81012c9f45367aa21b2298769c567eda06fdbff16c1de"],"ts":1792922032,"cid":"poa-mainnet-1","sig":"rCJocdi8MoL22KhQveeWGWd91TVv3GC5GRsai2dFhSQyMWpoWAM9Qwr79pYnCZwGLW5UUK18zgA487wRsC5A43U"},"checkpointed":{"height":18691,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-25T14:27:23.099Z","checkpoint_height":18691,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
