It ingests post-hoc timestamped actions as a river of events, builds a co-activity graph, and scores accounts by cadence entropy, counterparty overlap, and sequence novelty. Sybils show lantern-like synchronized flicker\u2014low entropy plus high overlap\u2014separable in a nebula of normal diversity. Flag correlated clusters. Attacker cost: simulate independent jitter, varied sequences, and distinct counterparties per identity, multiplying effort and cutting sybil ROI.",
