Abstract
This paper reports measurements of processes: ${e}^{+}{e}^{\ensuremath{-}}\ensuremath{\rightarrow}\ensuremath{\gamma}{K}_{S}^{0}{K}^{\ifmmode\pm\else\textpm\fi{}}{\ensuremath{\pi}}^{\ensuremath{\mp}}$, ${e}^{+}{e}^{\ensuremath{-}}\ensuremath{\rightarrow}\ensuremath{\gamma}{K}^{+}{K}^{\ensuremath{-}}{\ensuremath{\pi}}^{0}$, ${e}^{+}{e}^{\ensuremath{-}}\ensuremath{\rightarrow}\ensuremath{\gamma}\ensuremath{\phi}\ensuremath{\eta}$, and ${e}^{+}{e}^{\ensuremath{-}}\ensuremath{\rightarrow}\ensuremath{\gamma}\ensuremath{\phi}{\ensuremath{\pi}}^{0}$. The initial-state radiated photon allows to cover the hadronic final state in the energy range from thresholds up to $\ensuremath{\approx}4.6\text{ }\text{ }\mathrm{GeV}$. The overall size of the data sample analyzed is $232\text{ }\text{ }{\mathrm{fb}}^{\ensuremath{-}1}$, collected by the BABAR detector running at the PEP-II ${e}^{+}{e}^{\ensuremath{-}}$ storage ring. From the Dalitz plot analysis of the ${K}_{S}^{0}{K}^{\ifmmode\pm\else\textpm\fi{}}{\ensuremath{\pi}}^{\ensuremath{\mp}}$ final state, moduli, and relative phase of the isoscalar and the isovector components of the ${e}^{+}{e}^{\ensuremath{-}}\ensuremath{\rightarrow}K{K}^{*}(892)$ cross section are determined. Parameters of $\ensuremath{\phi}$ and $\ensuremath{\rho}$ recurrences are also measured, using a global fitting procedure which exploits the interconnection among amplitudes, moduli, and phases of the ${e}^{+}{e}^{\ensuremath{-}}\ensuremath{\rightarrow}{K}_{S}^{0}{K}^{\ifmmode\pm\else\textpm\fi{}}{\ensuremath{\pi}}^{\ensuremath{\mp}}$, ${K}^{+}{K}^{\ensuremath{-}}{\ensuremath{\pi}}^{0}$, $\ensuremath{\phi}\ensuremath{\eta}$ final states. The cross section for the OZI-forbidden process ${e}^{+}{e}^{\ensuremath{-}}\ensuremath{\rightarrow}\ensuremath{\phi}{\ensuremath{\pi}}^{0}$, and the $J/\ensuremath{\psi}$ branching fractions to $K{K}^{*}(892)$ and ${K}^{+}{K}^{\ensuremath{-}}\ensuremath{\eta}$ are also measured.

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 itClassification
machine, unvalidatedMachine predicted; both teacher heads agree on what is shown here.
