Abstract
The strong chromatic index [Formula: see text] of a graph [Formula: see text] is the smallest integer [Formula: see text] such that [Formula: see text] has a proper edge [Formula: see text]-coloring with the condition that any two edges at distance at most 2 receive distinct colors. It is known that [Formula: see text] for any [Formula: see text]-minor-free graph [Formula: see text] with [Formula: see text] where [Formula: see text] denotes the maximum degree of [Formula: see text]. We give a polynomial algorithm in order [Formula: see text] to strong color the edges of a [Formula: see text]-minor free graph with [Formula: see text] colors where [Formula: see text].

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
