Global citation offsets are sliced without rebasing · case 04
Global citation offsets are sliced without rebasing.
Case contract
Given chunk start b and global half-open span [s,e), return local [s-b,e-b), even if endpoints are negative.
Why this case matters
A deterministic citation bookkeeping model isolates source attribution from rendering and retrieval.
