Abstract
An alternative approach for the calculation of DFT-based reactivity descriptors involving derivatives of the energy with respect to the number of electrons and the external potential is further evaluated. Using functional derivatives with respect to the external potential, the finite difference approximation was avoided for the local calculation of the Fukui functions and the dual descriptor. A relevant set of molecules has been calculated after the optimization of computational parameters. It is shown that the new approach correctly predicts the nucleophilic attack on CH2O, the formation of CO metal complexes, the regioselectivity of monosubstituted benzenes, and the softest nucleophilic site in some ambident nucleophiles.

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
