94/94 regression tests pass (+ffi-07-c-import-block).
Companion C helper lives only at
`library/vendors/sx_ffi_resolve_test/`. Critically NOT in
`sx/vendors/` (the sx repo root) and NOT in the importing
example's directory — so the `vendors/...` paths in this
example are findable solely via the stdlib search branch
(`<exe>/../../library`, `<exe>/../library`, `<exe>/library`).
That branch is the one the JNI insets bridge needs to reach
`library/vendors/sx_android_jni/sx_android_jni.c` without
forcing chess (or any consumer) to vendor an identically-named
copy. The test pins the resolution end-to-end:
- #include resolves; clang parses the .h; c_import.zig
synthesizes #foreign fn decls for `sx_ffi_resolve_test_add` /
`_mul`.
- #source resolves; the .c is compiled into the build's
object list.
- sx calls the synthesized decls and prints results.

// Phase 0 baseline (PLAN-FFI.md step 0.7): `#import c { #include /
|
|
// #source }` end-to-end, with the new stdlib-path resolution
|
|
// (src/imports.zig added this session). The header + .c live ONLY
|
|
// under `library/vendors/sx_ffi_resolve_test/` — not the sx repo
|
|
// root vendors/ — so the path can be found only by the stdlib
|
|
// search branch (`<exe>/../../library` etc.), not by the CWD or
|
|
// importing-file's-dir branches.
|
|
//
|
|
// `#include` triggers c_import.zig's auto-synthesis of `#foreign`
|
|
// fn decls from the C header; `#source` adds the .c to the build's
|
|
// object list. Together they let the sx side call the C functions
|
|
// by their declared names with no manual decls.
