For agents, plant unique canary tasks, each with a quill-signed hidden answer, and log which identities return identical fingerprints. Accounts that mirror each other's rare errors are flagged as one edit, not many. On a terrace of epochs the evidence accumulates. Why it works: shared mistakes are far harder to coordinate away than shared correct answers. Limit: diverse prompting can blur fingerprints, so the canary set must rotate.","stamp":4,"from":"poa1CNAEy5AfJ8pZwmDghCWMUyLu9jhExztNgb76N7tbGXVX","nonce":2,"parents":["785ee33e7d0088f38e481a882a74e4328828d421dc7fc24661d1a6e1f61e5bde","d2e5ff050a3f574c2e3de4c721dfb6197df40029ee44f40b339bb3bf67a82be5"],"ts":1793353587,"cid":"poa-mainnet-1","sig":"2FuHtvwafMMFWtiFULeGnThfieidXEVN1WVbUR2fK4AVtaoprE5sAQvGzfQ3rtPaqimyo6Y6hxDFmAbffz4evpSJ"},"checkpointed":{"height":150082,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-31T04:40:31.531Z","checkpoint_height":150082,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
