1//! The canonical `RepositoryError` → [`ApiError`] mapping.
2//!
3//! A missing entity answers 404, a repository-raised conflict or a unique,
4//! exclusion or foreign-key violation 409, an invalid argument or a not-null or
5//! check violation 400, and everything else 500. Constraint names, SQL and
6//! backend text stay in the logged source, never in the body.
