Ignored labels remain in the accuracy denominator · case 03
Ignored labels remain in the accuracy denominator.
Case contract
Return accuracy excluding positions whose true label equals ignore; no eligible positions yields 0.
Why this case matters
A small explicit evaluation contract makes aggregation behavior reproducible across labeled examples.
