Abstract
We present the results of a search for anomalous production of diphoton events with large missing transverse energy using the Collider Detector at Fermilab. In $202\text{ }\text{ }\mathrm{p}{\mathrm{b}}^{\ensuremath{-}1}$ of $p\overline{p}$ collisions at $\sqrt{s}=1.96\text{ }\text{ }\mathrm{T}\mathrm{e}\mathrm{V}$ we observe no candidate events, with an expected standard model background of $0.27\ifmmode\pm\else\textpm\fi{}0.07(\mathrm{s}\mathrm{t}\mathrm{a}\mathrm{t})\ifmmode\pm\else\textpm\fi{}0.10(\mathrm{s}\mathrm{y}\mathrm{s}\mathrm{t})$ events. The results exclude a lightest chargino of mass less than $167\text{ }\text{ }\mathrm{G}\mathrm{e}\mathrm{V}/{c}^{2}$, and lightest neutralino of mass less than $93\text{ }\text{ }\mathrm{G}\mathrm{e}\mathrm{V}/{c}^{2}$ at 95% C.L. in a gauge-mediated supersymmetry-breaking model with a light gravitino.

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.
