FA-100164 / Annotation span alignment / Member archive
Character span misses a token that it partially covers · case 04
Character span misses a token that it partially covers.
Case contract
Return indices of tokens [a,b) that overlap span [start,end) with positive length; touching boundaries do not overlap.
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.
