Abstract
For several years now, there has been a strong drive in the automotive industry to displace the NiMH batteries in Hybrid Electric Vehicles (HEV) with lighter, more durable, more powerful and potentially less expensive Li-Ion batteries. These efforts have been hampered mostly by the concerns over the safety of the Li-Ion batteries. Such concerns have been overblown by merely focusing on abusive testing without paying equal attention to assessing the risk posed by such batteries in the event of a mishap. History shows that the automotive industry has been very successful in managing the risk posed by gasoline, a highly combustible fluid with an energy density 100 times more than the most energy-dense of advance batteries. This paper discusses a methodology developed for the risk assessment of advance batteries. Although the focus here is on the batteries used in hybrid, electric, or plug-in vehicles, the methodology itself, called Hazard Modes & Risk Mitigation Analysis (HMRMA), is quite general and can be used in other applications for batteries as well as for other components & parts that maybe considered hazardous. In addition, the methodology quantifies the risk associated with each hazard and becomes a valuable design tool to develop the most effective way of reducing the risk.

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
