Abstract
We report the direct measurement of the $^{7}\mathrm{Be}$ solar neutrino signal rate performed with the Borexino detector at the Laboratori Nazionali del Gran Sasso. The interaction rate of the 0.862 MeV $^{7}\mathrm{Be}$ neutrinos is $49\ifmmode\pm\else\textpm\fi{}{3}_{\mathrm{stat}}\ifmmode\pm\else\textpm\fi{}{4}_{\mathrm{syst}}\text{ }\text{ }\mathrm{\text{counts}}/(\mathrm{day}\ifmmode\cdot\else\textperiodcentered\fi{}100\text{ }\text{ }\mathrm{ton})$. The hypothesis of no oscillation for $^{7}\mathrm{Be}$ solar neutrinos is inconsistent with our measurement at the $4\ensuremath{\sigma}$ C.L. Our result is the first direct measurement of the survival probability for solar ${\ensuremath{\nu}}_{e}$ in the transition region between matter-enhanced and vacuum-driven oscillations. The measurement improves the experimental determination of the flux of $^{7}\mathrm{Be}$, $pp$, and CNO solar ${\ensuremath{\nu}}_{e}$, and the limit on the effective neutrino magnetic moment using solar neutrinos.

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
