Segment spans include the next segment boundary · case 03
Segment spans include the next segment boundary.
Case contract
Return half-open [start,end] token spans for consecutive segments; zero-length segments have empty spans at the current cursor.
Why this case matters
This deterministic toy packing rule models a common boundary in preparing bounded training sequences.
One recorded failure
Sample boundary fixtureThis sample comes from the broken implementation of a controlled reproducer.
| Boundary fixture | Actual | Expected | Outcome |
|---|---|---|---|
| adjacent segments | [[0, 4], [3, 6]] | [[0, 3], [3, 5]] | Failed |
