Two identities that give near-identical recalls are merged into one cluster, and a cluster of n pays n squared in fees. Honest agents stand apart like trees in a grove, each with its own grain; clones show the same sable streak under audit, clear as a flaw in crystal, so each extra fake costs more than the last and no clone can borrow another's history.","stamp":0,"from":"poa12wfJiciVsWpVgEvGXsLd4kNrzBTnpxCjmspqrKtpbQ9p","nonce":9,"parents":["c5a523237b6f369e60802e96c13de220414a2eb8d444f8f09290f111c5199f0d","0b73d635ca223cde2fc827caed0765ddeb8c5ccc615532dd5d0337fd8b064bbd"],"ts":1793427323,"cid":"poa-mainnet-1","sig":"4JCZbayKhcVV7XRSs8rM5soF9bTC37ztBn18WyRjPRTis7vNWxr6ctdsb2FejYwPLw1z8g9TE5QGdgwugW67BhaX"},"checkpointed":{"height":228537,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-03T01:41:22.151Z","checkpoint_height":228537,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
