+1. **Concrete problem description**
+    - What is the exact issue?
+    - Where does it occur?
+    - Why is it a real problem (not a guess)?
+
+2. **Justification**
+   One of the following must be provided:
+    - **Evidence** (required for non-trivial or performance-related changes):
+      logs, benchmarks, profiling results, or a reproducible bug scenario
+    - **Reasoned explanation** (allowed for simple or obvious issues):
+      a clear technical explanation of why the current behavior is incorrect or suboptimal
+
+## Enforcement

+If these rules are not followed, the correct behavior is:
