Abstract
Krabbe disease, a disorder caused by the deficiency of lysosomal galactosylceramidase, is typically associated with cerebral white matter degeneration, cortical sparing, accumulation of macrophages ("globoid cells"), and ultrastructural needle-shaped inclusions. Two sisters presented with progressive neurological deterioration beginning before the age of 2.5 years. The first, who died at the age of 9 years, exhibited profound destruction of cerebral white matter with sparing of subcortical fibers but no globoid cells. The brain of the second, who died at the age of 15 years and who had a proven galactosylceramidase deficiency, exhibited white matter destruction, previously undescribed circumscribed spongiform cortical degeneration (postcentral, inferior temporal, cingulate), and cerebellar atrophy, but no globoid cells. The peripheral nerve biopsies from both girls exhibited typical needle-shaped inclusions in Schwann cells. These observations confirm the rare reports that Krabbe disease is not always associated with globoid cells in the brain. Psychosine, which accumulates in the brain, might be toxic to cortical neurons following prolonged survival. The reason for the regional susceptibility in the cerebral cortex is unknown.

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 it
