Abstract
Processes with precisely known cross sections, like neutrino-electron elastic scattering ($\ensuremath{\nu}{e}^{\ensuremath{-}}\ensuremath{\rightarrow}\ensuremath{\nu}{e}^{\ensuremath{-}}$) and inverse muon decay (${\ensuremath{\nu}}_{\ensuremath{\mu}}{e}^{\ensuremath{-}}\ensuremath{\rightarrow}{\ensuremath{\mu}}^{\ensuremath{-}}{\ensuremath{\nu}}_{e}$) have been used by $\mathrm{M}\mathrm{I}\mathrm{N}\mathrm{E}\mathrm{R}\ensuremath{\nu}\mathrm{A}$ to constrain the uncertainty on the neutrinos at the main injector (NuMI) neutrino beam flux. This work presents a new measurement of neutrino elastic scattering with electrons using the medium energy ${\overline{\ensuremath{\nu}}}_{\ensuremath{\mu}}$-enhanced NuMI beam. A sample of 578 events after background subtraction is used in combination with the previous measurement on the ${\ensuremath{\nu}}_{\ensuremath{\mu}}$ beam and the inverse muon decay measurement to reduce the uncertainty on the ${\ensuremath{\nu}}_{\ensuremath{\mu}}$ flux in the ${\ensuremath{\nu}}_{\ensuremath{\mu}}$-enhanced beam from 7.6% to 3.3% and the ${\overline{\ensuremath{\nu}}}_{\ensuremath{\mu}}$ flux in the ${\overline{\ensuremath{\nu}}}_{\ensuremath{\mu}}$-enhanced beam from 7.8% to 4.7%.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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 itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
