Abstract
In the wake of a homicide, investigators were confronted with a castle doctrine self-defence argument that was difficult to refute with the tools and evidence at their immediate disposal. However, in his confession, the suspect claimed to have caused the stab wounds in an unusual manner. The victim's autopsy revealed that one of the stab wounds pierced the sternum and cut into the victim's heart, while another cut between ribs and stopped only at the knife hilt, causing a rib fracture. To provide insight into the likelihood of the suspect's narrative, investigators turned to injury biomechanics. It was possible to show the suspect's version of events had a low to an impossible chance of occurring through quantitative testing relating to sternum stabbing, rib fracture load, and ergonomic analysis, ultimately leading to a change in plea to 3rd-degree murder. This case illustrates the worth of injury biomechanics when dealing with complex homicides and why the standard investigative toolbox should include 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
