Support weighted recall divides by label count · case 02
Support weighted recall divides by label count.
Case contract
Return support-weighted recall for supplied labels; labels without support contribute zero; no support returns 0.
Why this case matters
A small explicit evaluation contract makes aggregation behavior reproducible across labeled examples.
