Abstract
In long bone development, the evolution of the cartilaginous anlagen into a secondary ossification center is initiated by the formation of canals. The excavation to create the canals is achieved through lysis of the two major cartilage components, aggrecan, and the type II collagen (COL2) fibril. The present study examines the lysis of the fibril. Because it is known that matrix metalloproteinases (MMPs) cleave COL2 in vitro at the Gly(775)-Leu(776) bond, it has been reasoned that, if such cleavage is detected in relation to the canals, it can be concluded that a collagenase is involved. Furthermore, because MMPs undergo change in domain structure with activation resulting in propeptide domain loss then, if such a loss is revealed in relation to the cleavage of COL2, this MMP is likely involved. The collective findings reveal that COL2 is attacked at the afore-described susceptible peptide bond at the surface of cartilage canals and, that MMP-13 cleaves it.

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
