Abstract
Parietal cells of the gastric fundic mucosa are small and contain only a few tiny mitochondria when they begin to differentiate from mucous neck cells. The canalicular ATPase activity characteristic of mature parietal cells is discrete in these young cells, whereas areas of very high activity are apparent in the Golgi complex, reticulum, nuclear envelope, mitochondrial wall, and plasma membrane. Close relations and contacts occur between mitochondria and these organelles, and the size and number of mitochondria increase progressively. These relations, as well as mitochondrial ATPase activity (a true differentiation marker), cease once the mitochondria become as numerous and large as those of a mature parietal cell. Our observations suggest that a secondary form of mitochondrial biogenesis, involving the massive participation of other organelles and independent of the classical mechanisms inherent in mitosis, occurs in parietal cells at the beginning of G1 phase during the 6 days of their maturation.

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
