FA-100150 / Annotation span alignment / Member archive
Deleted text clips spans to the surviving boundary · case 05
Deleted text clips spans to the surviving boundary.
Case contract
Delete [left,right). Map each endpoint x to x if x<=left, left if left<x<right, and x-(right-left) if x>=right.
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 |
|---|---|---|---|
| fully deleted span collapses | [[4, 3]] | [[3, 3]] | Failed |
