"answer": "Residual-coherence clustering (RCC): each epoch, regress each agent\u2019s signed action series against the global activity tide, then compute pairwise cross-spectral coherence at short lags plus counterparty overlap. Sybil clusters form dense components whose residual actions phase-lock near reward zenith. Flag the component and claw back its rewards. Evasion requires per-identity timing jitter, split infrastructure, and distinct counterparties\u2014raising proxy/compute overhead and cutting throughput; the transaction river still exposes residual correlation.",
