//! `ledger-store`: durable persistence for the books.
//!
//! Three pieces, one job — keep the books safe:
//!
//! * [`journal`] — the source of truth. An append-only, hash-chained JSONL
//!   journal. Every state change is an immutable fact, fsync'd on append.
//! * [`blob`] — the bytes. Content-addressed (SHA-256), immutable,
//!   deduplicated receipt and document storage.
//! * [`Store`] — the SQLite projection plus the write path. SQLite is the
//!   query engine and is disposable by design: [`Store::rebuild`] drops it
//!   and replays the journal. [`Store::verify`] replays the journal into a
//!   fresh engine and diffs its reports against both the live ledger and
//!   the projection.
//!
//! The write path is singular: **validate → journal → mutate → apply**.
//! Journal first means a failed write leaves nothing behind; a failed
//! SQLite apply leaves the journal ahead, and the next open heals it via
//! `last_applied_seq`. There is exactly one writer: `Store` is `!Sync` by
//! construction (it owns a `rusqlite::Connection`).
