Ledger
A double-entry accounting engine with an auditable, append-only history.
Ledger is a small but correct double-entry accounting engine. Every balance is derived from an immutable transaction log, so the books are always auditable and reconciliation is deterministic.
Highlights
- Strict double-entry invariants enforced at the database layer.
- Append-only event history for a full audit trail.
- Fast balance queries via materialized projections.
