Abstract
We investigate a new approach for resonance self-shielding calculations, based on a simplified and straightforward subgroup model, used in association with an improved Santamarina-Hfaiedh energy mesh. This subgroup model relaxes the need to represent the correlated slowing-down effects by optimizing the energy mesh. The resulting equations become sufficiently simple to reintroduce an accurate representation of other physical effects that are generally neglected, namely, the mutual shielding effect between different isotopes and the temperature correlation effect caused by an explicit temperature gradient in a resonant isotope. The resulting self-shielding model is shown to reach levels of accuracies that are similar to those of a Monte Carlo method.

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
