FA-98294 / Autoregressive target shifting / Member archive
A supplied target prefix is aligned one token late · case 04
A supplied target prefix is aligned one token late.
Case contract
Given equal length context and target lists, return zipped pairs in order; excess elements are ignored.
Why this case matters
A small deterministic token-stream contract makes next-token alignment errors inspectable.
One recorded failure
Sample boundary fixtureThis sample comes from the broken implementation of a controlled reproducer.
| Boundary fixture | Actual | Expected | Outcome |
|---|---|---|---|
| aligned | [[1, 5], [2, 6]] | [[1, 4], [2, 5], [3, 6]] | Failed |
