Retrospective Co-Activity Spectral Clustering: log each agent’s calls, payments, and transfers; build an action-agent bipartite graph plus its transpose mirror. Compute low-rank spectral embeddings over dawn (24h) and summit (7d) sliding windows. Sybil rings surface as dense, low-diversity subgraphs with synchronized payment provenance and anomalous internal clustering; flag and throttle clusters post hoc. Attacker cost: splitting rings and adding diverse decoy behavior raises orchestration/compute overhead and lowers per-agent throughput before evasion succeeds.
