Abstract
The Sudbury Neutrino Observatory (SNO) used an array of $^{3}\mathrm{He}$ proportional counters to measure the rate of neutral-current interactions in heavy water and precisely determined the total active (${\ensuremath{\nu}}_{x}$) $^{8}\mathrm{B}$ solar neutrino flux. This technique is independent of previous methods employed by SNO. The total flux is found to be ${5.54}_{\ensuremath{-}0.31}^{+0.33}(\mathrm{\text{stat}}{)}_{\ensuremath{-}0.34}^{+0.36}(\mathrm{\text{syst}})\ifmmode\times\else\texttimes\fi{}{10}^{6}\text{ }\text{ }{\mathrm{cm}}^{\ensuremath{-}2}\text{ }{\mathrm{s}}^{\ensuremath{-}1}$, in agreement with previous measurements and standard solar models. A global analysis of solar and reactor neutrino results yields $\ensuremath{\Delta}{m}^{2}={7.59}_{\ensuremath{-}0.21}^{+0.19}\ifmmode\times\else\texttimes\fi{}{10}^{\ensuremath{-}5}\text{ }\text{ }{\mathrm{eV}}^{2}$ and $\ensuremath{\theta}={34.4}_{\ensuremath{-}1.2}^{+1.3}$ degrees. The uncertainty on the mixing angle has been reduced from SNO's previous results.

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.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from it
