1//! Typed error boundary for the database crate.
2//!
3//! `RepositoryError` is the canonical error returned from the crate's
4//! database-facing public signatures, including the dyn-safe
5//! `DatabaseProvider` / `DatabaseTransaction` trait surfaces. It composes
6//! `sqlx::Error` and `serde_json::Error` via `#[from]`; runtime invariant
7//! failures are routed through `RepositoryError::InvalidState`. The
8//! filesystem-only [`crate::squash_baseline`] module carries its own error
9//! type.
