Abstract
For decades, human factor experts have pushed for the redesign of mining machine cabs to improve operator sightlines and ergonomics.Current cab design does not accommodate a full range of operator sizes, causing many workers to adopt non-neutral postures, which can increase their risk for musculoskeletal injury.This work examined the reachability of the zone of comfort (ZoC) for hand control locations in JACK software as defined for a range of operators.Once reach envelopes were overlaid onto the cabs for a variety of sized operators, no condition existed where an operator could reach 100% of the ZoC for hand controls.The best reachability was achieved by the largest operator, while the 5th percentile Latino female can fully reach only 29.7% of controls without using flexion.This work is the first to examine the validity of ISO 6682 from an equity, diversity, and inclusion perspective.

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
