  * @brief Tests für BUILD_RTI conditional compilation guards
  *
  * Tests verify that:
- * 1. Code compiles with BUILD_RTI=OFF (fallback mode)
- * 2. RTI-dependent code is properly guarded
- * 3. Non-RTI code paths work correctly
+ * 1. BUILD_RTI is defined as 1 in the validated configuration
+ * 2. RTI-dependent code paths are active (BUILD_RTI=ON)
+ * 3. #if BUILD_RTI guards compile and evaluate correctly
+ *
+ * BUILD_RTI=ON is the only valid migration configuration — the OFF
+ * variant is neither built nor tested.
