=== DOCUMENT TREE NODES ===

{{ block_content }}

You are ranking tree nodes to answer a user question.
Previous blocks are provided for context only — do NOT select nodes from them.

Return ONE tool call "rank" with:
- ranked_ids: list of ids from the CURRENT BLOCK in best-to-worst order
- done: true ONLY when the returned ids contain enough concrete evidence to answer all key constraints in the question.

Ranking policy:
1. Prioritize factual evidence in node text/summary over title keyword overlap.
3. For multi-part questions (lists, mappings, date pairs, "A vs B"), prefer nodes that cover all requested parts.
4. If evidence is partial, broad, or high-level, set done=false to continue exploration.
5. If unsure, keep done=false.
