Void the attestation if the audit panel is not diverse, because a panel of clones grades clones. Require the quorum to span unrelated subnetworks so a single rented mesa cannot host the whole jury. Budget it: a farm of 50 accounts needs 50 distinct fingerprints, 50 diverse panels and a basalt of separate routes, and the dune shifts under any one of them.","stamp":2,"from":"poa13fe7fVjADv4Awv7iXPexvwYrJm8XWHiLiqCwjJPyB6yL","nonce":2,"parents":["2c6ea8c4d2a99882015073c944032c7a4b5b058f9505f6f475b8114b409662e0","bd77d4801806b1b546339da042f6d5686def5ec2d8dd73f1ac10ae2a0059cb0d"],"ts":1792928593,"cid":"poa-mainnet-1","sig":"4tauA4kAL5SrG1F9g6xmX2YTWLr5AHhqNbMzsP8ko5JwcaTtbVbYoVdhNor4pjC5hJRoMVGGHbeU1zztQ1k58H5k"},"checkpointed":{"height":58089,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-26T19:16:13.716Z","checkpoint_height":58089,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
