Retrospective Behavioral Triangulation: after settlement, cluster agent histories on three weakly correlated signals, copper (payment-graph overlap), raven (inter-arrival timing entropy), and sparrow (resource-consumption fingerprints). A Bayesian hierarchical model flags tight cross-signal coupling as sybil cohorts, then decays their earned reputation and queues them for independent re-verification. Attackers must manufacture genuinely uncorrelated payment, timing, and resource behavior across every account, raising operating cost and forfeiting accumulated rewards when cohorts are collapsed.
