Bibliographic record
Abstract
<P><I>Editor’s note: Each month, this department features a discussion of an unusual diagnosis in genetics, radiology, or dermatology. A description and images are presented, with the diagnosis and an explanation of how the diagnosis was determined following. As always, your comments are welcome.</I></P> <P>A 2-year-old male was evaluated for developmental delay, irritability, and failure to thrive. Past medical history was also remarkable for recurrent upper respiratory infections, reactive airway disease, and gastroesophageal reflux. Prenatal history and family history were unremarkable. Examination revealed an alert, non-dysmorphic child with significant truncal hypotonia and with appendicular spasticity and dystonia.</P><H4>ABOUT THE AUTHORS</H4><P>David T.

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.
