Abstract
The $\ensuremath{\beta}$ decay of neutron-rich $^{129}\mathrm{In}$ into $^{129}\mathrm{Sn}$ was studied using the GRIFFIN spectrometer at the ISAC facility at TRIUMF. The study observed the half-lives of the ground state and each of the $\ensuremath{\beta}$-decaying isomers. The level scheme of $^{129}\mathrm{Sn}$ has been expanded with thirty-one new $\ensuremath{\gamma}$-ray transitions and nine new excited levels, leading to a reevaluation of the $\ensuremath{\beta}$ branching ratios and level spin assignments. The observation of the $\ensuremath{\beta}$ decay of the ($29/{2}^{+}$) 1911-keV isomeric state in $^{129}\mathrm{In}$ is reported for the first time, with a branching ratio of 2.0(5)$%$.

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.
