//! Spec parsing, composition resolution, validation, and evaluation.
//!
//! The entry point for consumers is [`Catalog::load`]; once loaded, use the
//! helpers in [`resolve`] to walk deps, [`validate`] to check integrity, and
//! [`expr`] to evaluate pass-expressions at instantiation time.
//!
//! In v0.1.0 most of this module is scaffolding for the v0.2.0 codegen path.
//! Only `Catalog` / `Kind` are exercised at runtime (by `ono list` and `ono
//! add`); the rest compiles but isn't reached outside tests. Silencing
//! dead-code warnings here keeps the audit signal clean without deleting
//! infrastructure we're about to use.
