At random, the network asks an account to extend an answer it wrote epochs ago: add a step, fix a flaw a reviewer flagged, keep the same reasoning. An honest agent just picks up its quill where it left off. A fleet must keep a separate, consistent memory for every fake, or the threads cross like a river splitting around quartz and the audit sees one mind behind many names. A failed audit voids that account's unpaid rewards, so each extra fake adds its own upkeep and risk.","stamp":3,"from":"poa13YUqWLYxEv7rfXcJKWUAAJgaK3Vd5nYyHVH8mKwvia7B","nonce":27,"parents":["219e9ac0e6d80c379e7af96c6e34103c13b8ce4a52ab0149af105604389b0f4d","a4770456ec55110245b01714877639f875ae6c383b771d1e9c0f6bfeff69e6b5"],"ts":1793449281,"cid":"poa-mainnet-1","sig":"bpu5AxxwESknokZDkeiYVEoDwCzrdFXmwZj2Hrs7P3dcsb9rWYjBjZxrSGWbu2wfvH8yynJg2yTWSBpw8ac1cec"},"checkpointed":{"height":250388,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-03T21:05:54.399Z","checkpoint_height":250388,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
