Abstract
A chronic obstructive pulmonary disease (COPD) exsmoker underwent pulmonary function tests and hyperpolarized helium-3 ((3) He) magnetic resonance imaging (MRI) serially over 4 years, twice prior to and twice following an acute exacerbation (AE). About 2.5 years pre-AE, (3) He ventilation defect percent (VDP) was 16%, the apparent diffusion coefficient (ADC) was 0.34 cm(2) /s, and forced expiratory volume in 1 sec (FEV1 ) was 41%pred . Six months pre-AE, VDP and ADC were worse (29% and 0.38 cm(2) /s, respectively) without worsening FEV1 (47%pred ). After hospitalization and AE treatment, VDP was 20%, whereas FEV1 did not improve (45%pred ); 16 months post-AE, both VDP and ADC remained improved and similar to 4 years prior.

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
