/**
 * @file test_build_rti_guards.cpp
 * @brief Tests für BUILD_RTI conditional compilation guards
 *
 * Tests verify that:
 * 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.
