Review Comment:
Yes — I simplified this in `e78603f50`. `MinMaxStatistics` is back to a 1:1
mapping with its input and keeps its original empty-input contract. The callers
now filter exact-empty files only for min/max ordering reasoning, then append
those files back when rebuilding groups so they remain in the scan plan.
