Compare a reference and current numeric stream with fixed bins, exposing both proportions and the largest distribution gap.
Required APIdef drift_report(reference, current, bins):
return {'reference': [...], 'current': [...], 'max_gap': ...}Think through the mechanism first if you want the extra reasoning step. It never blocks the editor.
