A class permutation is applied in the wrong direction · case 02
A class permutation is applied in the wrong direction.
Case contract
Given labels and permutation where permutation[new_index]=old_index, return remapped labels; out-of-range labels are -1.
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.
