//! Build-time guard that converts a silent "no binary produced" failure
//! into an immediate, actionable error.
//!
//! A crate can configure publishers and packagers that *require* a
//! compiled binary (container images, the binary-consuming publisher
//! manifests, Linux packages, OS installers, ...). If the build produces
//! no binary artifact for that crate — a mis-scoped release, an empty
//! `build.targets`, a wrong crate path — every binary-consuming stage
//! quietly logs `(no binaries, skipped)` and the release proceeds with a
//! source-only dist. The mismatch then detonates ~20 minutes later inside
//! the publish or container phase.
//!
//! [`check`] runs at the point in the pipeline where the binary artifact
//! set for each in-scope crate is known, and errors when a crate declares
//! a binary-requiring surface but no compiled-binary artifact
//! ([`ArtifactKind::Binary`] / [`ArtifactKind::UploadableBinary`] /
//! [`ArtifactKind::UniversalBinary`], or the per-target
//! [`ArtifactKind::Archive`] that wraps one) exists for it.

///   responsibility. A crate present in `set` but with no binary artifact
///   still fails: it was built yet produced nothing (the real mis-scope the
