"answer": "Co-Activity Residual Ridge (CARR): post-epoch, embed each agent by timing, counterpart diversity, and interaction-graph neighborhood. Fit a robust ridge regressor on a seed grove of verified organic agents, validated against a held-out sonnet of organic traces. Flag tight clusters whose residual vectors align and whose activity co-varies beyond baseline. Attacker cost: each sybil must sustain independent, organic-like graph placement and timing across epochs, not merely register; correlated residuals expose the cluster and forfeit rewards.",
