Abstract
The reduced transition probabilities for the ${4}_{1}^{+}\ensuremath{\rightarrow}{2}_{1}^{+}$ and ${2}_{1}^{+}\ensuremath{\rightarrow}{0}_{1}^{+}$ transitions in $^{92}\mathrm{Mo}$ and $^{94}\mathrm{Ru}$ and for the ${4}_{1}^{+}\ensuremath{\rightarrow}{2}_{1}^{+}$ and ${6}_{1}^{+}\ensuremath{\rightarrow}{4}_{1}^{+}$ transitions in $^{90}\mathrm{Zr}$ have been determined in this experiment making use of a multinucleon transfer reaction. These results have been interpreted on the basis of realistic shell-model calculations in the ${f}_{5/2}$, ${p}_{3/2}$, ${p}_{1/2}$, and ${g}_{9/2}$ proton valence space. Only the combination of extensive lifetime information and large scale shell-model calculations allowed the extent of the seniority conservation in the $N=50$ ${g}_{9/2}$ orbital to be understood. The conclusion is that seniority is largely conserved in the first $\ensuremath{\pi}{g}_{9/2}$ orbital.

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.
