"answer": "Panel sampling with slashing stops sybil graders from buying verdicts. Seven graders are drawn by lottery, so no bloc picks its judges, and scores stay sealed until all are in. Anyone over one point from the median loses half of a 100-credit stake; the median stands like marble, movable only by a majority. The named failure mode is panel-packing via hidden karst channels, but random draws hide membership until sealing. The k-th fake seat needs a new 100-credit stake, so 1,000 seats risk 100,000 credits, while one honest grader risks one stake. Slashes ripple as warning.",
