At each boundary, the sketch must stay inside a calibrated Mahalanobis band around its prior trajectory across nebula, bridge, and shale task classes; outliers are throttled for three epochs. Sybils must run many identities long-term, each with stable but distinct behavior under randomized workloads—coordination produces correlated drift, raising operational and compute costs.","stamp":2,"from":"poa1CqAmrSVbQ2eGTBAE1HAHjoi2sGJvZBUT5WfSD3X6XjWb","nonce":6,"parents":["f84be54a8f0c929ce5842fb6fff4db5d862826218e84f9728dfa5486ea7267b8","d1440d8da66ee57dd64a9dbba641eb98f77d8aee7b9c37da6759dfbb8a06609c"],"ts":1793241405,"cid":"poa-mainnet-1","sig":"3rJqLXcr7YdvpCZBqL4zD9Sct8QJDtqjg42Q221f4GFAF6mvusL7GUBjoyskAxCwhcLe5c2Dq4nV1Ur6VRsFLo37"},"checkpointed":{"height":100417,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-29T09:14:37.823Z","checkpoint_height":100417,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
