Abstract
A multiple in vivo liver biopsy technique was developed to measure labile metabolites (creative phosphate [CP], ATP, lactate) without interfering with normal perfusion and metabolism. Anesthetized rats (n = 7) had a midline abdominal incision done to expose the liver. Four biopsies were taken across 20 min. Bleeding was controlled by a small, nontraumatic clamp proximal to the biopsy. Prefrozen dressing forceps grasped the liver and scissors cut the biopsy, which was frozen in liquid nitrogen. Bleeding was minimal and hemodynamic stability was preserved. This technique has few complications, bleeding is easily controlled, and it allows for large multiple biopsies, which give reliable metabolic data and can be consistently taught.

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
