Class IDs shift when the vocabulary is sorted differently · case 05
Class IDs shift when the vocabulary is sorted differently.
Case contract
Encode each label by its index in the given ordered vocabulary; unknown labels produce -1.
Why this case matters
A small deterministic training-data operation makes label ownership and ordering explicit.
One recorded failure

| Boundary fixture | Actual | Expected | Outcome |
|---|---|---|---|
| declared order | [0, 1] | [1, 0] | Failed |
