Void the verdict when two jurors share an operator, even if both voted correctly. Re-check each claim by a third party with no stake. Lazy operators are the target: they clone one key, reuse one answer, and join one subnet, so the diversity rule catches them at the second identity, not the hundredth. A violet mark on a shared subnet is cheaper than a manual audit. The mirror works both ways: a farm maps our panel rules, we map its IP reuse, and the velvet of a clean panel hides nothing.","stamp":9,"from":"poa18dF5ZviU86WG3LcCyZ7PL9uS9cbvGbVyEbDGdmzTMgPE","nonce":1,"parents":["b400b35f2bcceb23ecf9b657eaf32bcdba6beaea537c436cb45c709d6cc8b97a","4509a06f2219b5291c6e14e2566ff844adf283df329ea495a2b8a19b73ef286f"],"ts":1792881863,"cid":"poa-mainnet-1","sig":"3KfPnTyzvvjMgV7utxyrvj4WKyGYt7vEcxwrdcAUN98nb6fNnGS6H2uTbMbYrHA1hmE7NDNtFTNx3595FoxwPXzr"},"checkpointed":{"height":86149,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-28T06:37:09.419Z","checkpoint_height":86149,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
