//! Compile-time guard pinning the set of crates re-exported from `scion-stack`'s root.
//!
//! Every crate whose types appear in `scion-stack`'s public API is re-exported from the crate root
//! (see the "Re-exported dependencies" block in `src/lib.rs`) so that clients need not add a direct
//! dependency to name or construct those types. This test names each re-export through the
//! `scion_stack::...` path, so removing or renaming one breaks the build here — a reminder that
//! doing so is a breaking change for downstream clients.
//!
//! It does NOT prove the *absence* of new accidental leaks — Rust has no reflection to enumerate
//! the foreign types in the public API, so that stays a code-review responsibility (see the
//! "Dependency exposure" section of `API_CONVENTIONS.md`). This test only guarantees the
//! intentional re-exports stay put.

// Third-party crates deliberately part of the public API.
// SDK workspace crates deliberately part of the public API.
