+// This .cpp file was added as a workaround for clang-tidy limitations.
+// Meson runs clang-tidy directly on headers (.hpp), but the tool relies on
+// compile_commands.json, which only defines context for .cpp files.
+// This results in invalid diagnostics when headers are processed alone.
+// The workaround ensures headers like test_utils.hpp are properly analyzed
+// via corresponding .cpp compilation units using HeaderFilterRegex settings.
