Abstract
A 56-year-old man reported 1 year of progressive decline in the vision of both eyes, left more than right. He had difficulty explaining his symptoms. Although he could clearly see the letters of text when reading, he struggled to verbalise and understand the content. He took amitriptyline and sertraline for anxiety and depression. Visual acuity was 6/12 (20/40) in each eye with normal ocular examination. He read simple material in a slow, halting fashion and made several errors. He scored 20/30 on mini-mental state examination. Formal visual field testing identified an incongruous left homonymous defect with good reliability (figure 1A). Figure 1 Homonymous field defect in posterior cortical atrophy. (A) 24-2 Humphrey visual fields showing left homonymous field defect. MR scan of the brain showing no structural lesion, only mild posterior atrophy with prominent sulci within …

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
