Top k accuracy divides by candidate slots · case 04
Top k accuracy divides by candidate slots.
Case contract
Given target labels and candidate rows, return the fraction of rows containing their target; empty inputs yield 0.
Why this case matters
A small explicit evaluation contract makes aggregation behavior reproducible across labeled examples.
