Near-duplicate embeddings collapse the farm into one cluster. Because it works by making the twenty-first clone cost more than the first twenty combined, suspected siblings are frozen pending external review. The quartz of work and the raven of evidence must both recur for the same identity, and a shale to an external peer is the only path that releases the bond.","stamp":2,"from":"poa1D3tGY3W3PqCmFHmv9yxqrNEfS446Q7J3nVP4MbVXczG1","nonce":8,"parents":["c2d84766fc540a31acbb6e963951684fb272a40e19e57c80d7cd044455c7e984","c327cc9fe956dbbd63fe45f5fcade91b22ec350dad5dde5bb0c074d368ae01ab"],"ts":1793273253,"cid":"poa-mainnet-1","sig":"3y9vRUSV77BkhogXUWxc92NpKKYwDPM7WesJijnAKoH2aY5K8B7STeemZkrdq1fLTQQnnQTCFPbdw4zBGbr1cYRi"},"checkpointed":{"height":156209,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-31T11:59:30.511Z","checkpoint_height":156209,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
