# Page metadata in chunks

## Why deferred

v1 Strategies and Qdrant payloads don’t need page numbers. Page-as-section markdown was rejected (arbitrary cuts). Page info is citation UX, not chunking semantics.

## Trigger

Users (or the chatbot) need “see page N” citations, or Chunk Preview should show page ranges per chunk.

## Approach to try

1. During PDF parse, map character/block offsets → page numbers
2. Attach optional `page_start` / `page_end` on Chunk / ChunkMetadata (nullable for DOCX)
3. Do **not** inject `## Page N` into markdown unless a Strategy specifically needs it

## Success criteria

- DOCX path unchanged (null pages)
- Query/answer path can cite pages without changing Strategy ranking logic
