Because selection is random and the echo seed is unrevealed until close, a hostile operator cannot dodge the sample, so colluding to grade clones' junk is a spiral 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 11% of its standing plus a seat ban.
