## Overview

This Spring Boot service manages an item catalog and customer orders. Clients use item endpoints to create, retrieve, filter, update, rate, and delete items; order endpoints place orders or cancel them. Order placement looks up items, checks and reduces stock, persists order data, and builds a response; cancellation restores stock before deleting the order. Item operations use a service/repository layer and include caching. The tree and sampled code support the main calls, but the README is empty and OrderRepo implementation details were not sampled.
