Why is this work in the frame?
A frame that forgets how it found something cannot be audited. These are the routes that admitted this work.
Full frame distilled prediction
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)
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
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.

Abstract
The Sudbury Neutrino Observatory has precisely determined the total active (${\ensuremath{\nu}}_{x}$) $^{8}\mathrm{B}$ solar neutrino flux without assumptions about the energy dependence of the ${\ensuremath{\nu}}_{e}$ survival probability. The measurements were made with dissolved NaCl in heavy water to enhance the sensitivity and signature for neutral-current interactions. The flux is found to be $5.21\ifmmode\pm\else\textpm\fi{}0.27\mathrm{(}\mathrm{stat}\mathrm{)}\ifmmode\pm\else\textpm\fi{}0.38\mathrm{(}\mathrm{syst}\mathrm{)}\ifmmode\times\else\texttimes\fi{}{10}^{6}\text{ }{\mathrm{cm}}^{\ensuremath{-}2}\text{ }\text{ }{\mathrm{s}}^{\ensuremath{-}1}$, in agreement with previous measurements and standard solar models. A global analysis of these and other solar and reactor neutrino results yields $\ensuremath{\Delta}{m}^{2}={7.1}_{\ensuremath{-}0.6}^{+1.2}\ifmmode\times\else\texttimes\fi{}{10}^{\ensuremath{-}5}\text{ }{\mathrm{eV}}^{2}$ and $\ensuremath{\theta}={32.5}_{\ensuremath{-}2.3}^{+2.4}$ degrees. Maximal mixing is rejected at the equivalent of 5.4 standard deviations.
