Abstract
Abstract Cuellar et al. recently found that methodological flaws in black-box studies of forensic firearms analysis mean that validity cannot be determined from those studies. Their paper can also be read to indicate that the presence of some of these flaws means that the associated study is so unsound that it can only be used to plan future properly designed validation studies. We seek to clarify that each of the identified flaws, taken individually, does not necessarily prevent studies from contributing to a strong, cumulative research basis for forensic practices. That said, we agree that the overall body of research must avoid the flaws identified by Cuellar et al., and, based on their analysis, it appears the overall body of research has not avoided these flaws. We go on to suggest practices that can help ensure forensic science studies can efficiently and safely build on each other.

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
