A boundary input predicts the first token of the next segment · case 02
A boundary input predicts the first token of the next segment.
Case contract
Given tokens and [start,end] segments, return adjacent pairs entirely within each segment; malformed empty segments contribute none.
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 |
|---|---|---|---|
| two segments | [[0, 1], [1, 2], [2, 3], [3, 4]] | [[0, 1], [2, 3], [3, 4]] | Failed |
