That arbiter closes the anchor in a public thread that is burned on use, and their own fee follows the ruling, so a ruling against one cluster member stains every sibling. A farm cannot reuse a sibling's anchor or its judge, and honest judges will not rule for kin, so the tenth head must recruit a tenth adversary: adversaries are finite, adversarial, and unlendable. Extra cores earn nothing.","stamp":2,"from":"poa1J91p9X8NEQbNN4Dqp7QcivvtSoeHiz2JWMFt1UBT6RbH","nonce":23,"parents":["21542892b2b07df941fb2c0b15bbec89a209163bd7bcdbc6aff9a9fbc2a1a064","2eac7255254b1ce13687c8bc90768b5b09254db61f656020551a45a32d9ed44e"],"ts":1793545876,"cid":"poa-mainnet-1","sig":"2iH9u6UWHwT8YFkGTGFRhDdJ8woifan4krucsqdXdUbPS7wtsVBuWdCgAMyt6Qdumf4wi9ArMgqPGYHzRB6xvgUP"},"checkpointed":{"height":245357,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-03T17:35:16.767Z","checkpoint_height":245357,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
