Abstract
It has long been recognized that Copernicus’ models in the Commentariolus bear a striking resemblance to those of Ibn al-Shāṭir (14th-c. Damascus). A number of scholars have postulated some sort of transmission but have denied that Ibn al-Shāṭir’s geocentric models had anything to do with the heliocentric turn. Rather, the assumption has been that they were used by Copernicus solely to resolve the irregular motions of the planetary deferents brought on by Ptolemy’s equant. Based on proposals for direct transformations of Ibn al-Shāṭir’s models into those of Copernicus and an alternative reading of Copernicus’ so-called Uppsala notes, it is argued here that Ibn al-Shāṭir’s models in fact have a “heliocentric bias” that made them particularly suitable as a basis for the heliocentric and “quasi-homocentric” models found in the Commentariolus.

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
