## Overview

This is a restaurant food-ordering backend: customers and staff interact with tables, sessions, orders, catalog and payment operations through an HTTP API. The principal flow is an API order request delegated to order application logic, with table/session handling supporting dine-in use and persistence holding domain state. The tree also shows authentication, invoices, complaints, feedback, dashboards and real-time notifications. Source evidence is selective; unsampled capabilities are represented as subsystems without speculative call edges.
