Case 3: An eight-month-old boy with failure to thrive
Bibliographic record
Abstract
A full-term eight-month-old boy was admitted to hospital for evaluation of failure to thrive (FTT). After initially thriving, by six months of age his weight had dropped from the 90th to the 15th percentile. He had a four-month history of nonbloody, nonbilious emesis and a worsening feeding aversion. Stool pattern remained normal. There was no sweating or increased work of breathing with feeds. Physical examination revealed a pale, emaciated infant with little subcutaneous fat. He was alert, active and engaging. He was afebrile with stable vital signs. His weight was 6.89 kg (<3rd percentile; 69% ideal body weight) (Figure 1). His head growth was stable (25th percentile) and length was preserved (75th percentile). He had no dysmorphic features, a flat anterior fontanel and normal tone. The remainder of his examination was unremarkable. Figure 1) The patient’s growth chart. Note the plateau in weight, resulting in the crossing of multiple percentile lines Investigations included a normal complete blood count, electrolyte levels and renal function tests. A work-up for fat, carbohydrate and protein malabsorption was negative. An upper gastrointestinal swallowing study revealed normal anatomy. Lansoprazole and domperidone were initiated for gastroesophageal reflux disease. His vomiting improved; he tolerated fortified feeds, demonstrated adequate weight gain and was discharged home with follow-up. One week later, he was readmitted with weight loss and new symptoms. A further test led to the diagnosis.

How this classification was reachedexpand
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 itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
