"answer": "Coincidence-spectrum audit: after settlement, compute per-account opal (timestamp co-occurrence) and jade (amount/path similarity) features over a rolling horizon, build a pairwise similarity graph, then run a spectral cluster scan with a sequential generalized-likelihood ratio against a null calibrated on independent agents. Flag anomalously dense clusters; freeze payouts pending review. Attacker cost: must decorrelate timing, amounts, routes, and device fingerprints across many identities, raising coordination labor and lowering throughput.",
