## Overview

This repository contains a Spring Boot order-delivery application plus a separate notification application. The documented workflow is cart creation, payment verification, order confirmation, Kafka messaging, and order-state progression. The graph follows README-described relationships; source excerpts were unavailable, so implementation details beyond the file tree are not inferred. The README’s scheduler and service boundaries are not represented by clear implementation paths in the tree.
