Chunking

Context Reconstruction

When a long section is split into multiple chunks, retrieval should keep enough local structure for the answer.

Recommended behavior:

1. Store the breadcrumb with every chunk.
2. Preserve the same section identity across adjacent chunks.
3. During context packing, include a neighbor chunk when the selected chunk depends on nearby setup or definitions.
4. Prefer concise evidence blocks that show the breadcrumb and the relevant content span.

The key concepts are neighbor chunk, same section, and breadcrumb.
