0.2.0 - 2026-07-01

kuatia-dashboard: a server-rendered dashboard and REST API for observing a Kuatia ledger over HTTP. Browse accounts, postings, transfers, and the event log; inspect per-account balances computed in Rust.

The SQL backend stores binary identifiers as hex text and structured columns as JSON text instead of opaque blobs, so a ledger can be audited directly with SQL tooling. The SQLite and PostgreSQL schemas were unified into a single 001_init.sql.

Initial release.

Append-only, multi-asset, UTXO-style ledger. Value is tracked as signed postings with no mutable balance fields. Transfers atomically consume and create postings, enforcing per-asset conservation (sum(consumed) == sum(created)).
Intent API: movements (pay, deposit, withdraw) resolved into concrete postings by the core, committed through a single reserve → finalize saga with automatic retry and LIFO compensation.
Content-addressed transfers (double-SHA-256 of canonical bytes) for idempotency and tamper evidence.
Account policies: NoOverdraft, CappedOverdraft, UncappedOverdraft, SystemAccount, ExternalAccount, with append-only versioned accounts and snapshot pinning to guard against TOCTOU races.
Durable crash recovery via a phase-tracked write-ahead saga record and Ledger::recover() (roll-forward, not rollback).
Dumb-storage Store trait split into focused sub-traits, with an in-memory backend and a SQLite/PostgreSQL backend (kuatia-storage-sql).
A conformance test suite (store_tests!) applied to every storage backend.
Snowflake-style i64 IDs generated in Rust; the database never assigns IDs.
Compile-time swappable monetary backing (i64 default, i128 via the i128 feature).
