FA-98003 / Training label alignment / Member archive
Batch sampler selection is ignored when labels are paired · case 03
Batch sampler selection is ignored when labels are paired.
Case contract
Given examples and labels of equal length plus selected indices, return paired rows in index order.
Why this case matters
A small deterministic training-data operation makes label ownership and ordering explicit.
One recorded failure
Sample boundary fixtureThis sample comes from the broken implementation of a controlled reproducer.
| Boundary fixture | Actual | Expected | Outcome |
|---|---|---|---|
| nonprefix subset | [[0, 10], [1, 11], [2, 12], [3, 13], [4, 14]] | [[4, 14], [0, 10]] | Failed |
