# 0019 — `#import` is non-transitive (C-function scope across files)

> **Status: superseded — kept for reference.** Relocated from the old
> `examples/issue-0019/` fixture during the test-layout migration. The behavior

## What it probed

`main` imports both `c_wrapper.sx` (which declares C `extern` functions) and
`other.sx`. `other.sx` should *not* gain access to `c_wrapper`'s C functions
transitively — using one should produce the "not visible; #import the module that
declares it" diagnostic.

- `main_good.sx` — the valid arrangement.
- `main_bad.sx` — the arrangement that must be rejected.
- `c_wrapper.sx`, `other.sx` — the imported modules.

## Caveat (why it doesn't run as-is)

The fixture uses **relative** imports (`#import "../modules/std.sx"`), which only
resolve relative to a specific working directory and violate the project's
"always `package:`/module-path imports, never relative" rule. It is not runnable
from the repo root and is not wired into the suite. If revived, rewrite the
imports to the standard `modules/...` form and pin expected output; otherwise it
can be deleted (the scenario is already covered by `0706-modules-import-non-transitive`).
