## Commands run

```powershell
cmake -S . -B build -DMAG160C_BUILD_TESTS=ON
```

Result: failed because cmake is not installed or not on PATH.

```powershell
g++ -std=c++17 -DMAG160C_STATIC -DMAG160C_HAS_LIBUSB=0 -Iinclude -Isrc src\core\error.cpp src\core\context.cpp src\c_api.cpp tests\cpp\test_c_api.cpp -o build_task1_test.exe
.\build_task1_test.exe
```

Result: passed with exit code 0 and no assertion failures.

## Test results

- CMake/CTest verification could not run because `cmake` is unavailable in the environment.
- Direct MinGW C++17 compile/run verification passed.

## Concerns

- The planned CMake verification remains unverified until CMake is installed or available on PATH.
- A generated local executable `build_task1_test.exe` exists from substitute verification.

## Self-review notes

- Public C ABI is free of C++ types.
- Unknown error codes return MAG160C_ERR_UNKNOWN_CODE.
- Null init output pointer returns MAG160C_ERR_INVALID_ARGUMENT and last_error mentions out_ctx.
- Successful init clears last_error and returns a non-null context.
- Context construction does not require hardware or libusb.
