swaitsandClaude Fable 5.1 6b7dccd1ee feat(audit): audit runs and attestations are journaled (P8)
A claim that someone checked the books is evidence the CPA handoff rests on,
so it is a journal fact and replays: audit.run (a programme run through a
day at the books' figure head, with the hashes that make it reproducible and
the two filed workpapers), receipt.attested, entry.reviewed and
period.attested. Behind the journal feature audits, schema 20; no figure
moves. The figure head is the last line that bears on a figure: filing a
workpaper, a run or an attestation never makes an audit stale, an entry,
document, close, settings or role change does, so a period is attested only
on an audit that still describes the books. A receipt reading that differs
from the entry is recorded as disagreeing and never counts; whether a claim
counts is derived against the bar when asked, never stored.

The store also reads what a ledger cannot: the chain, the database against
a replay, stored and extracted files, the access log, duplicate files, and
the backups' standing handed in by the server. Fixture old-books/p8_before
was written by the version before this one and opens to its figures.
period.attested was the tests' placeholder for an unknown event type; they
use ledger.not_yet_written now.

//! `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`).
