DIVERGENCE: independent re-derivation does NOT match recorded within 0.05 -> FLAG for reconciliation. INT-2 LEVER: soft-axis held-out separation AUROC = 0.6903, anisotropy (var-along-u / mean-eig) = 219.88x. Geometric precondition CONFIRMED (axis separates right/wrong out-of-fold AND is a genuine anisotropic mode); the generation rescue rate remains Tier-C (model required)."
