1//! Typed error boundary for the database crate.
2//!
3//! `RepositoryError` is the canonical error returned from every public
4//! signature in this crate, including the dyn-safe `DatabaseProvider` /
5//! `DatabaseTransaction` trait surfaces. It composes `sqlx::Error` and
6//! `serde_json::Error` via `#[from]`; runtime invariant failures are
7//! routed through `RepositoryError::InvalidState`.
