//! `ledger-core`: canonical double-entry bookkeeping semantics.
//!
//! This crate is the engine. Everything else in the workspace — persistence,
//! import, the oracle harness, the UI — builds on top of it and never
//! reimplements accounting logic.
//!
//! Design rules (see `AGENTS.md` at the repo root):
//!
//! * Money is [`Money`]: an exact [`rust_decimal::Decimal`] plus an ISO 4217
//!   currency code. Binary floats never touch money paths.
//! * A [`Ledger`] is single-currency for now (see `docs/requirements.md` R-5).
//! * All mutations go through [`Ledger`] commands (`create_entry`, `add_line`,
//!   `post_entry`, `reverse_entry`). Posted entries are immutable; corrections
//!   are reversing entries.
//! * Reports ([`trial_balance`], [`balance_sheet`], [`profit_and_loss`]) are
//!   pure functions of a ledger, which is what makes the semantic oracle
//!   (`docs/oracle.md`) possible.
