Phase 5A: Audit passes — shuffle control collapses, gains are real
Phase 5B: Transfer SUCCESS — vec_M4 beats scalar CB by +0.25 Gamma, +0.31 rho on frozen CIFAR
Phase 5C: Online FAILURE — vec does worse than scalar CB online despite better frozen credit
Core finding: bottleneck is in local surrogate / co-adaptation, not estimator quality
