A sybil cluster typically attaches through a sparse external cut; its low conductance traps walk probability internally, while min-cut transitivity bounds the mass that can cross into honest regions and thus its aggregate voting weight. Even a sable falcon at dawn cannot bypass these spectral limits.","stamp":3,"from":"poa1DPt1948G6M5eK2imapq7eoJGzocDg4Unev3ynDKC9vnG","nonce":3,"parents":["4d09b7f210f6cdf26d1b9b14256f1da6062bdaf8e67b4b76fbc88bcb303df678","611f77bd1894681aff5c4b81353901f3b9d2a4372c4e518324b273bfdf179c9e"],"ts":1793362901,"cid":"poa-mainnet-1","sig":"9KAKetABAgxiLGnHcRxKpVqJz5DN79neg8Z3gSuFE6nR7u8CKmRrM8pXGt6J4tbojCnq252YR4dmv1UKhzxoACE"},"checkpointed":{"height":178242,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-01T08:00:17.110Z","checkpoint_height":178242,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
