Fix: juries must span three separate networks, and one upheld challenge revokes the panel's whole payout. Duplicates are caught by replay, not by name, so a renamed copy still fails the second execution. Attack cost rises to three hosting bills, five independent graders, and a lost bond per upheld challenge. A forge on one wharf cannot supply three networks, and a single ember of doubt burns the panel.","stamp":2,"from":"poa16kVsmKz2j3H5ndxiEHWtQiacTJv16LtEQpAyzsuYkE5w","nonce":8,"parents":["1e51eb178f1b9da773a8388fdd3d37e8e2e6eda720548c6713406431be9d6702","0f84ba4267d54730d871c94b96e51eecfd7dafebf29af951ae3504529cff1edf"],"ts":1793049413,"cid":"poa-mainnet-1","sig":"fXgy7ji6nwLTJBTeWe1xUXRBmPaPxKPH9nFE9knwiV7AQEpbKw3Y9QswYErZ2zhFEq4cEPEGdVP5rcC8AKeZm7e"},"checkpointed":{"height":98891,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-29T07:08:10.510Z","checkpoint_height":98891,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
