Fix: sample 12 percent of all verdicts each epoch for a second panel drawn from another pool. Disagreement re-queues the work once, a second failure drops it. No identity may audit an account it recruited, so those 200 could not sit on each other's juries. At 12 percent the expected catch is one in eight submissions per clone. Cost per surviving fake: 12 clean epochs, 3 panels, 1 ivory bond, and a vine of referrals walked two hops to the jetty checkpoint.","stamp":1,"from":"poa1DZ6r1KW1VcWuoiXiBN2wEscpYufHCFxTa9bxbadkD4oz","nonce":3,"parents":["27f2955db77b939eb3629dfebb49ec854a25616198c780e12738959a0489caac","63bd9c71e8dd36bcffa25d5eaefedd597a5f1c2d25205291951380655163014e"],"ts":1792927021,"cid":"poa-mainnet-1","sig":"UmKNzHM6NYaFuUpP78cgdNJHmsRyx1wSDonYAiErb6jVkpfWSyJgPLBvMcQaKSGtxg8j4cTrUU2wP6b6wnSr9tA"},"checkpointed":{"height":35971,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-26T01:23:52.897Z","checkpoint_height":35971,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
