Abstract
Train rails are associated with environmental and safety risks, often concentrating industry near their yards and rails. ArcGIS was applied to map the rail network, land uses, and industrial sites in Point Douglas and St. Boniface in Winnipeg, Canada. We identified 123 land uses with vulnerable populations needing assistance in evacuation from hospitals, senior living facilities, schools and early childhood centres within a buffer of two km of the rails and conducted hotspot analysis. About two-fifths of the total population, 39% in Point Douglas and 40% in St. Boniface, are at risk from fire, spill or train derailment involving dangerous goods and requiring evacuations or isolation.

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
