Abstract
Abstract Nitrogen rich plasma polymer films (L‐PPE:N) were prepared by low‐pressure RF plasma using a 1:1 mixture of ethylene and ammonia and aged for 345 d in four different ambient conditions: (i) at room temperature (RT) in air; (ii) at RT in nitrogen; (iii) at −20 °C in air and; (iv) at −20 °C in nitrogen. The films were analyzed by X‐ray photoelectron spectroscopy (XPS) and by time‐of‐flight secondary ion mass spectrometry (ToF‐SIMS) at various intervals over the duration of the experiment. The ageing of primary amines, NH 2 , was followed by chemical derivatization with 4‐trifluoromethyl benzaldehyde. Storage at −20 °C, mostly independently of ambient atmosphere, slowed down ageing to almost undetectable levels as evaluated by the analytical methods used for this study. magnified image

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
