Abstract
The validity of the Mayo‐Lewis (ML) terminal model for copolymer composition in nitroxide mediated copolymerization is systematically tested by simulation. Significant deviations in copolymer composition from ML behavior occur under various parameter combinations before the nitroxide quasi‐equilibrium condition (QEC) is reached. Maximum deviations are usually below 5 pp, and absent at conversions higher than 3%, but after 10% in some cases. High reactivity ratios lead to larger deviations; low reactivity ratios (faster cross‐propagation) produce near ML behavior. An additional continuous radical source leads to faster attainment of the QEC and reduces the deviations from ML behavior.

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
