+Clear stale 'settled' paths from all users' schedules and add new Major records.
+
+When the requirement YAML data is updated with new category names, existing users'
+settled paths (stored in user_schedule JSON) no longer match the new requirement
+tree structure. This command clears those stale paths and adds Major records for
+newly available concentrations.
+
+The verifier's auto-settle feature will re-assign courses that can only satisfy
+one requirement; users only need to manually re-settle ambiguous courses.
+
+Usage:
+    python manage.py clear_settled_paths          # dry-run (default)
+    python manage.py clear_settled_paths --apply  # actually write changes
