Two weeks earlier, she had been butted in the head by a ram while working with a herd. She sustained a small abrasion over the left frontal area of her head. Six days after the injury, she noted the development of local erythema, swelling and pruritus. She had no fever, chills or systemic symptoms. Self treatment with topical polymyxin B sulfate/bacitracin zinc (Polysporin, Pfizer Inc, USA) yielded no improvement in the lesions. At her initial assessment, two weeks after the injury, an examination showed three lesions above the left eyebrow, one measuring 1.5 cm × 0.6 cm and the other two measuring 0.3 cm to 0.5 cm in diameter. The lesions were vesicular, with an erythematous rim. Lymphadenopathy was not detected and there was no ocular involvement. Within five days after her initial presentation, the lesions became nodular and the erythematous rim more vivid (Figure 1). Tender preauricular lymphadenopathy developed, and she reported fatigue and general malaise but remained afebrile. Aspiration of a lesion was done to obtain material for culture. Hematology and chemistry laboratory investigations were within normal limits. Two days later, she developed fever and chills, with periorbital and facial edema. Blood cultures were negative. Intraocular involvement was ruled out with an examination by an ophthalmologist. Despite 72 h of intravenous clindamycin phosphate (600 mg every 8 h), the edema and lymphadenopathy worsened and she was switched to meropenem 1 g intravenously every 8 h. Improvement was detected within 48 h, and she completed a 10-day course. As the edema resolved, the nodular lesions developed a superficial crust, which subsequently separated, revealing underlying papillomatous lesions. Over the next three weeks, the lesions slowly decreased in size and erythema. Complete healing without scarring ensued. What was the cause of her skin lesions?

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.
