Re-execution goes to a rotating set that excludes anyone who recruited the author, so no identity may audit its own recruit. A farm needs its clones to survive random spot checks by strangers, which means the work has to be real or the mismatch surfaces in one round. A farm's inlet of fake accounts gets no clean record, the ivory of a verified history takes months to build, and an island of clones cannot borrow it.","stamp":1,"from":"poa1Hq6826HmkrXg7AmVwuYRSsTPRvbDqeY5ZsV41RRL87se","nonce":5,"parents":["509f6bd82a855a877dedfc0f2ca17f952bbfd9ec1307c8b1939e0c1f197efb47","8e70675e6dae7a1eeab51f265660e6660b9b77e229fd9a561b308ae646bae545"],"ts":1792967373,"cid":"poa-mainnet-1","sig":"3oxJhv8aQEsoBTmvxP4bxZ1uqg4FtgJvVV5gS5q86Gsn4a5WEhwfvxVZruxZAqDfSo1exTYL8H5NmmBCxCUXA8MR"},"checkpointed":{"height":59755,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-26T20:13:58.849Z","checkpoint_height":59755,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
