v1.1.0

Lucendex v1.1.0

Non-custodial, deterministic routing engine for XRPL.

Release Notes v1.1.0

Partner API hardening

• Added body-size enforcement (1 MB max), proper request replay handling, and generic error responses so the auth middleware fails closed instead of leaking internal states.
• Required INTERNAL_TOKEN for the /internal/v1/ledger endpoint and log/propagate failures when quote registry writes or ledger updates fail.
• Rate limiter now fails closed on KV errors instead of defaulting to “allow”.

Router & KV improvements

• Introduced a “system” namespace in the in-memory KV store to persist the latest ledger index; the router automatically reads/writes this value so TTL math stays accurate.
• Router now accepts the KV dependency, exposes setter/getter helpers, and uses the shared ledger index in health responses.

Indexer + Usage billing

• Added quote-registry validation before recording completed trades: the indexer now verifies the memo hash against quote_registry, logs the partner, writes usage_events, and cleans up the registry entry.
• Usage fee calculation is captured when recording a trade, and quote registry access is granted via new migrations so the indexer has the required permissions.
• The indexer publishes ledger progress to the API via the new internal endpoint, keeping router TTLs up to date.

Database migrations

Consolidated all legacy migrations (001–007) under backend/db/migrations, added 009_indexer_quote_registry.sql (permission fix), and 010_network_state.sql (tracks validated ledger for lag reporting).
