2026-03-24Add Phase 5: vector field audit, frozen CIFAR transfer, online pilotYurenHao0426
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 Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
