doubleentry 0.8.0

An immutable, tamper-evident double-entry bookkeeping engine: one pure rule core, exact integer money, identity derived from the idempotency key, and one append-only RFC 6962 Merkle log with inclusion, consistency and sealed-balance proofs and C2SP checkpoints, in memory (sync) or over SQLite and PostgreSQL (async).

//! Every read, once: balances, the trial balance, statements, the rollup,
//! open items and balance assertions.
//!
//! Each read is a **plan plus a pure fold**. A [`BalanceQuery`] resolves
//! against one log prefix into a selection and picks the cheapest store
//! read — a maintained balance, the balance after a position, or a fold of
//! the key's posting rows; the fold applies the whole selection to every
//! row again, so a store that filters less is still right. The façades
//! (`Journal`, `Ledger`) only fetch pages and feed the folds here, so every
//! store answers every read identically, and SQL never adds money.
