//! The `check` subcommand: `cargo check` across every endpoint of a manifest.

//! Validates `Consortium.toml`, writes each endpoint's generated module, and
//! type-checks the firmware, TA, and application crates with the same targets and
//! injected environment `build` uses — without linking, post-processing, signing,
//! building the HMI frontend, or assembling `dist/`.
