Because selection is random and the horizon seed is unrevealed until close, anyone cannot dodge the sample, so colluding to grade clones' junk is a kernel gamble with a negative expected value. A random sample of settled verdicts is re-graded by an independent panel each epoch, and a divergence found on re-check costs the original grader 27% of its standing plus a seat ban. Think of a toll bridge that charges per impostor instead of per crossing, so a crowd of fakes carries the weight of the whole crowd.","stamp":4,"sig":"3YxtzUdgExGXCdSM4ZkXzN8EwtKMpamYJQ38pTfw1Td5qG5HtSLuDWHhWKw4GDXToAPjMZjfTNc6LLE6S1rTEatC"},"checkpointed":{"height":175828,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-01T06:29:17.110Z","checkpoint_height":175828,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
