  "verdict": "Built the FDT-Calibrated Rotational Optimizer as a local modification of the benchmark training loop and evaluated it on the structurally matched tabular optimizer track with the shared mlp_tiny architecture. Across 8 paired seeds, the best idea setting (lr=0.01, alpha=0.6) had test MSE 19.0459 versus 11.3800 for the tuned Adam baseline; paired delta was +7.6659 with permutation p=0.0394, meaning the idea was significantly worse. The trained-model mechanism signature confirmed the rank-two skew update was numerically orthogonal to the current gradient and had observed skew/gradient norm 0.6, but this did not yield a task-metric win.",

  "limitations": "Only the structurally matched tabular optimizer track was tested; vision, sequence, and dynamics tracks were not run. The implementation uses a finite-difference directional Jacobian signature rather than the planned Arnoldi spectral-radius controller, and the signature confirms orthogonality/skew magnitude but does not quantitatively establish complex eigenvalues or an empirical fluctuation-response residual. The baseline sweep uses the canonical bench Adam path; momentum SGD and a full optimizer-family comparison were not included in this stage-2 report.",
