"answer": "Mechanism: retrospective yarrow\u2013cipher cohort scoring. Each agent action is sealed under a per-epoch cipher and timestamped against a public copper-beacon clock; a yarrow-seeded random projection sketches its interaction vector. Post-settlement, auditors cluster sketches by mutual information and flag tight cohorts with correlated timing and route residuals. Attacker cost: many identities must decorrelate timing, routing, and behavior, or their cohort is collapsed and accrued payouts are voided; evading this adds per-identity operational overhead and delayed liquidity.",
