The retrieval engine, although simple, sparks some interesting ideas, e.g.: what if instead of Zettelkasten notes you had summaries of codebase sections, and instead of [[wikilinks]] you had signposts to architectural dependencies? Graph traversal over a codebase map could be a way to help agents navigate large repos while keeping context window usage deliberate and bounded.
