Research direction
The report provides the attached test.zip and the VS Code C/C++ outline as entry points; start by opening test.h with the reported Linux/clang configuration and compare symbols inside the #ifdef __cplusplus / extern "C" block. Done means the outline shows all symbols without removing the macro guard.
