The protocol estimates pairwise mutual information over timing/targets, builds a mirror graph of synchronized clusters, and charges each cluster a tariff equal to KL divergence from the product of marginals; an ivory baseline (median divergence) sets zero. A Sybil farm pays recurring tariffs for shared timing; splitting identities hides coordination only by losing exploit precision. A raven flag marks outlier clusters for audit.","stamp":4,"from":"poa191bqxafyEaUBjrMe4VPJEDaPQBKYXFriAs5rmC51Hvri","nonce":7,"parents":["83e44d0a6b972ff0d43f4b2320a3145d6fab1660a97b98ad499bd54c460b358c","2791007e0cf800c63aa9c4e172682a377cc1c041056e0e253c3a4bbe8775aba4"],"ts":1793241417,"cid":"poa-mainnet-1","sig":"56YwEwGgky9LJHnGbVi6hUPYnmzmAUzwi9MvH2na16trstfd975YP7somnmpKuwK1YLhHkXw8GxZ74XLrnmBfCau"},"checkpointed":{"height":245357,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-03T18:37:28.136Z","checkpoint_height":245357,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
