FA-99669 / Chunk citation alignment / Member archive

Equal offsets from distinct sources are merged · case 04

Equal offsets from distinct sources are merged.

Member previewVariant 4 · 3 implementations · 6 checks per implementation

Case contract

Rows are [source,start,end]; merge overlapping or touching spans only for same source and sort by source then offsets.

Why this case matters

A deterministic citation bookkeeping model isolates source attribution from rendering and retrieval.

One recorded failure

Sample boundary fixture

This sample comes from the broken implementation of a controlled reproducer.
