Abstract
= 597) persons with conviction histories for violent offenses; approximately, two thirds of whom completed risk-need-responsivity based violence reduction treatment services. Indigenous men tended to score higher on VRS static, dynamic, and total scores and to be classified as higher risk; however, there were no differences between the groups in treatment change. In the aggregate sample, VRS total scores demonstrated broadly medium to large effects in the prediction of violent and general recidivism (median AUCs = .72 [Indigenous] and .71 [non-Indigenous]) across ethnocultural groups. Conversely, VRS change scores (controlling for pretreatment score) were significantly associated with decreased violent and general recidivism for Indigenous persons (median AUC = .62) but considerably less so, with small or lower effects, for non-Indigenous persons (median AUC = .48). These results were upheld when effect sizes were aggregated across the samples through meta-analysis. Calibration analyses demonstrated that integrating risk and change information via logistic regression modeling decreased disparities between ethnoracial groups in rates of recidivism associated with VRS scores. Implications for violence risk assessment, treatment, and management using the VRS with Indigenous persons who have a history of criminal violence are discussed.

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
