A citation in joined text is attributed to the wrong chunk.

Member previewVariant 3 · 3 implementations · 6 checks per implementation

Given chunk starts and lengths, map point p to its containing chunk index using half-open intervals; return None for gaps or out of range.

Why this case matters

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