Subject: [PATCH] ### Summary

Fix type mismatch in ternary that causes GCC `-Werror=extra` to fail.

#### Details

GCC's `-Werror=extra` enforces stricter type consistency in ternary expressions, in this case const-qualified unsigned variable with enum literal.

### Tested

- Built with ToT clang and GCC 13.3.0 on Linux x86_64.
- All existing tests pass
