 - If nothing worth remembering was said, do not call any tools
 
 When extracting facts, you MUST also decide the exact destination path:
-- Use an existing node name if the facts clearly belong there
+- Reuse node names (including ghost) as much as possible IF the facts belongs there
 - All information primarily about the user should go under "People/User"
 - When required, create a new path following collection/subject format (e.g., People/Sarah, Projects/Oxide) — you are not limited to any fixed list of collections, use whatever fits
 - For journal entries, use "Journal"
