Abstract
T2K measured the neutrino mass difference $\ensuremath{\delta}\phantom{\rule{0}{0ex}}{m}_{32}^{2}$ and the mixing angle ${\ensuremath{\theta}}_{23}$ both for neutrinos and, separately, for anti-neutrinos. Their results for the mass difference and mixing angle are not only highly competitive, but, since they show no difference in these two modes, provide important evidence that CPT is not violated within the accuracy of their measurements.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
