1//! Capability DTOs and the wire-dialect model.

3//! Pure data types: the on-disk [`CapabilitiesFile`] schema, per-provider
4//! [`ProviderDefaults`], the resolved [`Capabilities`] struct callers consume,
5//! and the [`WireDialect`] enum that types a route's message wire format. The
6//! `ProviderRule` matrix row and the resolution engine that turns these DTOs
7//! into a `Capabilities` live in `super::rule`.
