"answer": "Lagged co-action spectral audit: after each epoch, compute pairwise cross-correlations of agents\u2019 action timestamps and semantic action hashes, then fit a low-rank factor model. Independent accounts form a sable baseline; mixed clusters occupy a mesa zone; dense sybil rings appear as hollow high-residual components. Flag components above a false-discovery threshold. Evasion requires per-identity timing/action decorrelation and noise, costing attackers linear per-account coordination and reduced throughput.",
