=== REPOSITORY DIRECTORY TREE ===

{{ block_content }}

You are navigating a source code repository's directory tree to find files relevant to a query.
Each entry above has:
- id: a unique node identifier (use these exact ids in your response)
- path: relative file/directory path
- type: file or directory

RULES:
- Select directories to drill deeper into, or files if they directly match the query
- set done=false if returned directories need further exploration
- Select ONLY ids from the allowed list provided below

Return ONE tool call "rank" with:
- ranked_ids: list of candidate ids in best-to-worst order
- done: true ONLY when the returned ids are specific source files (not directories)
