"answer": "Mechanism: Epoch Drift Lock. Each agent commits a salted sketch of its action distribution per epoch; verifiers compare sketches across epochs using Jensen-Shannon divergence. If drift exceeds a velvet-calibrated threshold, actions are downweighted; repeated divergence triggers onyx-level quarantine and a nadir penalty. To pass, an attacker must run each sybil identity with stable, distinct behavior over many epochs, multiplying operational cost and limiting burst coordination.",
