Abstract
The prevalence of eating disorders has increased in the industrialized world in the last few decades (1,2) , and 0.2–1% of all adolescent girls (3) and 1–4% (4) of all college-aged women in the United States suffer from anorexia nervosa (AN), an eating disorder associated with significant bone loss (5–17) and increased fracture risk (11,18,19) . Often undiagnosed, the true prevalence is likely higher, and variants of AN are estimated to be twice that diagnosed strictly by DSM-IV criteria (20,21) . In addition, AN has been increasingly reported in males, who now comprise 5–15% of this population (22) , and also demonstrate significant bone loss (23) , In a recent study from Canada, disordered eating attitudes and behaviors were reported in more than 27% of girls aged 12–18 yr (24), with significant increases in Drive for Thinness, Body Dissatisfaction, and Bulimia subscales (Eating Disorders Inventory) with age. Table 1 summarizes the characteristic features of eating disorders (25) . These keywords were added by machine and not by the authors. This process is experimental and the keywords may be updated as the learning algorithm improves.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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 itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
