Abstract
OBJECTIVES: Porotic lesions of the skull (cribra orbitalia and porotic hyperostosis) are one of the most common types of lesion identified in archaeological human bone and have also been found in hominins and non-human primates. Because of the frequency with which such lesions are found there has been extensive debate on the possible causes and whether they are linked, with much of the debate centering on anemia. The biological approach to diagnosis in paleopathology used by Don Ortner and recently proposed more formally as a technique to facilitate diagnosis in paleopathology by Simon Mays may offer a means of answering some of the questions surrounding these lesions. MATERIALS AND METHODS: A review was undertaken of biomedical information on changes in the distribution of marrow type and pattern of conversion of red and mixed marrow, and the potential for re-conversion of yellow marrow with age. The range and type of other conditions that might result in the development of porous lesions were also considered. RESULTS: Combining information from the biomedical literature on marrow type and patterns of conversion with age, with careful evaluation of the type and location of porous lesions in the skull and across the rest of the skeleton will assist in suggesting a diagnosis. DISCUSSION: A wide range of conditions can produce porous lesions in the cranial vault and the orbital roof, but due to anatomical structures and physiological factors such lesions are more likely to occur in the orbital roof. Anemia can produce lesions in both locations, but evidence of marrow expansion is required to confirm it as a cause.

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
