# exp-6 C FFI Scalar Imports Alpha Fixture This fixture is experimental compiler-supported coverage for `.llm/EXP_6_C_FFI_SCALAR_IMPORTS_ALPHA.md`. It is current compiler support after matching Slovo and Glagol exp-6 gates. The fixture covers one imported C function: ```slo (import_c c_add ((lhs i32) (rhs i32)) -> i32) ``` The Slovo wrapper calls it only inside lexical `unsafe`: ```slo (unsafe (c_add 40 2)) ``` `slovo.toml` makes the fixture usable through project-mode native build gates. The top-level test intentionally exercises the exp-6 test-runner boundary: the interpreter-style test runner must report that C imports are unsupported for direct test execution, while hosted native build uses the local `c_add.c` companion as an explicit link input. No pointer types, allocation, deallocation, raw-memory operations, ownership or lifetime model, generated header, library output, C exports, or stable ABI promise is part of this fixture.
