FA-100195 / Annotation span alignment / Member archive
Windowed export keeps original coordinates after clipping · case 05
Windowed export keeps original coordinates after clipping.
Case contract
Clip spans to [left,right), discard zero-width results, and return coordinates relative to left while preserving labels.
Why this case matters
A small offline annotation transformation keeps span coordinates explicit when text or token boundaries change.
One recorded failure
Sample boundary fixtureThis sample comes from the broken implementation of a controlled reproducer.
| Boundary fixture | Actual | Expected | Outcome |
|---|---|---|---|
| partial both sides | [[3, 6, "x"]] | [[0, 3, "x"]] | Failed |
