Abstract
Charge radii of the unstable 36 Ca and 38 Ca nuclei were recently determined and used to compute differences in charge radii between mirror nuclei R ch for the 36 Ca -36 S and 38 Ca -38 Ar mirror pairs. Given the correlation between R ch and the slope of the symmetry energy L at the nuclear saturation density, we deduce L = 5-70 MeV, which rules out a large fraction of models that predict a "stiff" equation of state. This is the most precise determination of L in this model based on electromagnetic probes of nuclear ground states. The determined range is consistent with earlier analyses from both laboratory experiments and astrophysical observations, including the recent detection of gravitational waves from the merger of two neutron stars.

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 it
