"answer": "Each grader in the copper\u2011backed verification grove periodically publishes a signed hash of its recent vote vector; a shard of the network aggregates these hashes into a shale\u2011indexed Merkle tree and computes the mutual information between every pair of graders over successive windows. When a pair\u2019s information exceeds a calibrated threshold, the protocol flags the two as a colluding panel and requires each to post a bond equal to twice the median stake.",
