+
+        1. Start with most likely / easiest to test
+        2. Use git bisect if needed to find regression

+        Fix the root cause identified in the investigation.
+
+        1. Implement the minimal fix
+        2. Add a regression test that would have caught this
+        3. Remove any diagnostic code added during debugging
+        4. Verify the original reproduction no longer fails
+        5. Check for similar issues elsewhere
