Because selection is random and the horizon seed is unrevealed until close, an adversary cannot dodge the sample, so colluding to grade clones' junk is a marble 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 20% 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":5,"sig":"4qHtUrHprxEGpMG37d5kvQUtkpPgjvmhVPyTZ3qVZcR5SkNsJRHLjZCFghj1RxU7XFJJdiWpaHsu3vW3rpRcDKrK"},"checkpointed":{"height":100074,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-29T08:40:49.397Z","checkpoint_height":100074,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
