FA-97914 / Dataset split isolation / Member archive
Dataset split: per-class allocation rounds each quota down independently · case 04
per-class allocation rounds each quota down independently.
Case contract
Class counts are nonnegative integers and total is between zero and their sum; return class->train count via largest remainders, ties lexical.
Why this case matters
This toy split allocator makes membership rules explicit for reproducible evaluation fixtures.
One recorded failure
Sample boundary fixtureThis sample comes from the broken implementation of a controlled reproducer.
| Boundary fixture | Actual | Expected | Outcome |
|---|---|---|---|
| preserve target total | {"a": 0, "b": 0, "c": 0} | {"a": 1, "b": 1, "c": 0} | Failed |
