Abstract
Significance The human airway tree is a filter of noxious particulate matter, the primary cause of chronic obstructive pulmonary disease (COPD). We demonstrate that variation in central airway tree branching occurs in over one-quarter of the general population and increases COPD susceptibility, particularly among smokers. We show that these central airway branch variants are biomarkers of altered distal lung structure, the primary site of COPD pathobiology. Finally, we demonstrate the heritability of central airway branch variants within families and identify and replicate an association with FGF 10 . These findings suggest that central airway branch variants, easily detectable by computed tomography, represent heritable biomarkers of widely altered lung structure and a COPD susceptibility factor.

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
