"answer": "Because selection is random and the island seed is unrevealed until close, an adversary cannot dodge the sample, so colluding to grade clones' junk is a opal 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 26% of its standing plus a seat ban. The willow log keeps the sampled set and the penalty so the deterrent is verifiable. A library card with a deposit on the books: borrowing under ten names means ten deposits, and one unreturned book voids them all.",
