Abstract
An 8-year-old boy presents with a 3-week history of red, itchy, raised lesions that developed vesicles and black crust. The lesions started on the neck and inguinal region but became generalized within a few days. He was diagnosed as having varicella and sent home with symptomatic management. A few days later, he was seen in the ED because of fever and persistence of the eruption. He was prescribed oral cephalexin for a possible secondary infection of the varicella. He has not improved and is finally admitted to a regional hospital for further evaluation. Physical examination shows a generalized eruption of erythematous papules, most of which have a dark crust in the center, as well as a few papulovesicles on the extremities, including the palms and soles (Fig. 1). He has enlarged inguinal nodes and complains of intense pruritus. The differential diagnosis includes varicella, herpesvirus infection, and vasculitis. Figure 1. Eruption consisting of erythematous papules, most of which have a dark crust in the center, and a few papulovesicles on the right lower extremity. Results of laboratory studies include: Urinalysis is negative for protein and erythrocytes and a urine culture is sterile. Results of bacterial culture and polymerase chain reaction testing for herpes group viruses from the skin lesions are negative. Additional evaluation leads to the diagnosis. An 8-year-old boy who has a history of recurrent pneumonia, CHARGE association, repaired tetralogy …

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.
