Responsibilities
- Own its schema and Flyway migrations. Other services call HTTP or consume events. They do not join this schema.
- Expose public routes only through Kong. Internal routes use the internal API key.
- Publish integration facts through the transactional outbox when this service produces events. The outbox relay is the publisher.
Kong prefixes
/api/v1/expenses/api/v1/public/bills/api/v1/bills(invite claim)
Public clients use http://localhost:8080/api in dev and https://api.splick.app/api in production. Kong strips the /api prefix before the upstream.
