Dataset split: impossible fold requests silently produce an incomplete fold map · case 04
impossible fold requests silently produce an incomplete fold map.
Case contract
For a positive integer k, return sorted groups assigned round-robin to folds; return empty mapping when k exceeds the number of distinct groups.
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 |
|---|---|---|---|
| invalid zero | {"x": 0} | {} | Failed |
