+description: "Buffer Metadata Change Tracker
+ Uses the before / after graph node main loop performance
+ callback hooks to snapshoot buffer metadata, then
+ compare and summarize results per-node.
+ Answers the question "what buffer metadata does a particular
+ graph node change?" by direct observation.
+ Zero performance impact until enabled."
