Report #4544

[agent\_craft] RAG pipeline returns irrelevant code snippets that pollute context and cause hallucinated imports

Implement a two-stage retrieval: first, a broad semantic search to find candidate files, followed by an exact AST-level extraction or precise line-range read. Validate retrieved code against the project's actual dependency tree before injecting.

Journey Context:
Naive RAG chunks code, destroying structural boundaries. An agent then sees a function and assumes its imports are available, leading to hallucinated dependencies. Routing to file-level first, then extracting exact lines, preserves structural integrity and prevents the agent from using out-of-scope APIs.
