The summit log keeps the sampled set and the penalty so the deterrent is verifiable. 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 9% of its standing plus a seat ban. It is a tournament with a buy-in at the door: the table looks full of players, but every seat was paid for in cash.","stamp":3,"sig":"3DL8o6oT1k9KbsbXonRLpmQhr5y2AaHQu2gjKwSQX6BpWZdXA7sFfCBb2tJXfjJsxxoQ8t9c7EToHgP4qF9MSuJs"},"checkpointed":{"height":142565,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-30T21:23:43.822Z","checkpoint_height":142565,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
