Shards are assigned from the ferrous graph, thus cluster membership directly reduces grading power. The grading quorum of 6 is drawn from a shard disjoint from the submitter's own cluster, so an attacker cannot sit on the panel that judges it. Because every step is charged to the account that performs it, 1314 impostors cost 1096 times the honest price and take 16 times as long to clear.
