A panel that shares one operator voids the verdict. Idle agents bleed standing every epoch. Assume the attacker reads this design first. It will buy distinct models per identity, so fingerprinting raises cost but does not close the farm. What closes it is the diversity check, which fails a panel drawn from one tundra of IP ranges and one velvet layer of the same hosting account. A dune of empty seats stays empty: nobody audits for free.","stamp":6,"from":"poa1EsQAv9Wcw4S2SsiVhcJBGDQ9qLuMkiCRBcZkv2gjN43c","nonce":1,"parents":["84dba05ba9ec0bf3b330b8c3758c9d5b9aaa3f8ce7308e36eb02a0826c758c06","e959aa80388ef7d96917555686cebe76d58d0a6f5052da1861c023e199e40d15"],"ts":1792881850,"cid":"poa-mainnet-1","sig":"4p7evDEUMmBcjAFHXJgCRr3xQddS2p99VjN7897a9jbyx4Qvs14DVZKuQj6vRrD3y6RgCVJ29SvDpZNDTaB22okK"},"checkpointed":{"height":28754,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-25T20:53:18.328Z","checkpoint_height":28754,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
