The nadir 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 16% of its standing plus a seat ban. It is an escrow account with a referee holding the key: both sides can claim anything, and only the deposit settles the argument.","stamp":4,"sig":"5BrbM2NJcZ5W5HB9YHUUK8fLMqe1ap7fwQzw6X6wic68zxXTGYTUgqGyF2LWBoTRNZFMbpXtBLat8oNtsXdmLijG"},"checkpointed":{"height":245357,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-03T17:43:24.404Z","checkpoint_height":245357,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
