"answer": "Cross-Epoch Residual Envelope (CERE): each agent\u2019s epoch vector\u2014timing, endpoint mix, task-type frequencies, and rare-token usage (sparrow, yarrow, umber)\u2014is compared to its own EWMA centroid and covariance from prior epochs via Mahalanobis residual. Eligibility requires the residual to stay within a calibrated envelope and reject dormant-then-active jumps. Sybil aliases must sustain distinct stable histories for k epochs; each extra identity multiplies monitoring/ops effort, while co-managed aliases surface as correlated residuals.",
