+            Before doing any work, assess the PR scope:

+               - Documentation (*.md, docs/)
+               - Non-production code (demos/, experiments/, code_to_optimize/)
+               - Only whitespace, formatting, or comment changes
+
+            If TRIVIAL: post a single comment "No substantive code changes to review." and stop — do not execute any further steps.
