Store::verify compares the whole SQLite projection, every table row for row, against a fresh projection of the journal; verify_and_heal rebuilds a drifted database (keeping the old file) at every server start and via the new books.verify tool, which also re-hashes every blob. The GUI checks the server's database read-only and every stored file, and shows the result. rebuild() also drops stale WAL/SHM files. site/: the wanderbooks website (just site, just publish). install.sh: OS detection (Windows points to WSL2), C compiler and git checks, WANDERBOOKS_REPO. Windows: no directory fsync off Unix; .exe-aware lookup. Repo justfile: check, build, install, demo, site.

//! `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`).
