Module chunks 

Context window construction from the structural index.

Each chunk is a rich text window centered on a symbol:

symbol name + signature

• doc comment (tree-sitter extracted)
• parent module/crate path
• callers (top N by frequency)
• callees
• co-change neighbors

Additional source types:

• doc: Markdown files chunked by heading section. Each section becomes one chunk with a breadcrumb of parent headings prepended for context.
• commit: Git commit messages (subject + body), keyed by commit hash.

The quality of the embedding is directly upstream of the quality of the index. Better extraction -> better context windows -> better embeddings.
