 - All fixtures must self-assert; use `test_assert.h` helpers so `ctest` fails on mismatched WinAPI behaviour.

 ## Debugging Workflow
 - Reproduce crashes under `gdb` (or `lldb`) with `-q -batch` to capture backtraces, register state, and the faulting instruction without interactive prompts.

 Self-checking Windows fixtures run through CTest. They require a 32-bit MinGW cross toolchain (`i686-w64-mingw32-gcc` and `i686-w64-mingw32-windres`).
 
 ```sh
-ctest --preset fixtures
+ctest --preset debug
 ```
 
 This will cross-compile the fixture executables, run them through `wibo`, and fail if any WinAPI expectations are not met.
