The cipher assignment is published and vertex records each panel. The grading quorum of 5 is drawn from a shard disjoint from the submitter's own cluster, so an adversary cannot sit on the panel that judges it. A farm of 4892 identities would post 938 proofs and burn roughly 83 thousand dollars in locked value before a single vote counted.
