A new retrieval method for codebase knowledge bases, termed the 'history path', has been introduced to address questions that traditional methods like vector search or graph traversal cannot answer. This fourth path leverages Git history to provide context on why code was written in a certain way, rather than just what it does. By encoding Git history into graph edges, specifically through 'FILE_CHANGES_WITH' relationships, this approach reveals patterns such as documentation and code evolving in sync, offering deeper insights into code design decisions.
