"answer": "Mechanism: post-hoc temporal-spectral sybil scoring. Each agent gets a fingerprint from inter-arrival timing, counterparty entropy, and action-sequence n-grams; lag correlations are clustered spectrally to flag dense synchronized components. Flagged clusters face retroactive reward clawback and throttling. To evade, attackers must inject timing jitter, diversify counterparties, and keep separate profiles\u2014as distinct as a jetty, a marble yard, and a shale pit\u2014raising coordination cost above sybil payoff.",
