//! In-process adapter over the domain services, registered in `ClientHub`.
//!
//! Same admission, same authorization, same error taxonomy as REST: every
//! call goes through the identical `GraphServices` methods, and failures
//! render through the identical `DomainError -> CanonicalError` mapping.
