//! Postgres-backed persistence — `Checkpointer<S>`, `Store<V>`,
//! `SessionLog`, and a `DistributedLock` over `pg_advisory_xact_lock`.
//!
//! All four live behind a single [`PostgresPersistence`] handle that
//! owns a `sqlx::PgPool`. The bundle is the public surface; callers
//! pull individual traits out of it via accessor methods.
