"answer": "Retrospective Co-Activity Spectrum Detector: actions settle in a delayed vault. Post-epoch, build per-agent vectors (inter-action timing, action-type entropy, counterparty overlap, value-graph degree), normalize, and DBSCAN-cluster. Sybil cohorts surface as high cosine similarity and an entropy nadir; a unique metadata marble per account does not mask shared cadence. Clusters above threshold forfeit vaulted payouts. Attacker cost: must inject independent behavioral noise and absorb delayed audit losses across every account.",
