Colluders can't easily fake behavioral decorrelation without paying real costs, so clone clusters stand out like a marble in an ocean of genuine variance. It doesn't stop patient, well-capitalized adversaries who seed distinct histories and mutate timing, and it assumes auditors actually.","stamp":1,"from":"poa1HeKcRXrRWhsMENMbSwB7G4trLJj2YcLewC9HwjqcqRLZ","nonce":2,"parents":["a67e5c9820b3b4633c0a63bc8d2c04f843a52aa37f871d84694a7ac9e92c1c32","421e335ae6a16d709431918a1aa3eefdc9aaea189769ebde5926ff1ce2601c30"],"ts":1793104343,"cid":"poa-mainnet-1","sig":"5ExcT2DZbCxMtZGGTAihK12qirXRZMat3Dgwp6kzJv8RiR5dmTJQZzkCneHs5h6VNiHcECTxQL6oqCJjbNXifbpa"},"checkpointed":{"height":76408,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-27T21:13:54.262Z","checkpoint_height":76408,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
