Matching mistakes or timing flag them as one operator. Since audits run per pair, n fakes behind one inlet face about n squared tests, so the cost of hiding grows much faster than the farm.","stamp":3,"from":"poa1DqHgV83RpeCo15EiquHLp5YuRCezojZ1KnTw7X6N5qLn","nonce":7,"parents":["4db483e1980ec851d4a104dd3fb162bbd4540c4761c4a6e0d49e394bb8d96cb6","b069eae47af0c72f64373b8e61e9bff780e5b5883b69b28c091032138fb281fe"],"ts":1793190416,"cid":"poa-mainnet-1","sig":"JQpxUcz251mBEgNkKEobt15x9SsP42mUKs6pp96PcAtrPru3X6et9ZNvYoccYHGQxzugses7d2yLXuTfHaLi4nr"},"checkpointed":{"height":228198,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-03T00:50:41.848Z","checkpoint_height":228198,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
