Grading juries are stake-weighted: each juror locks 100 coins, and scores far from consensus cost a 20% slash. This quill must write honestly, since the median signal alone sets grades. Cost math: N captured seats cost N×100 coins under a standing 20% burn risk, so a takeover bleeds faster than grading fees ever repay. Collusion finds no cover either: coordinated off-consensus votes look identical to solo deviation, so the plume of plausible deniability shields nothing.
