## Overview

This Laravel application appears to provide an API for product and category browsing, inventory management, order creation and lookup, and user authentication. The principal order flow validates a request, creates an order, delegates item creation, and returns the loaded order; product and inventory operations form separate catalog and stock-management stages. The graph reflects sampled controller, service, and repository behavior where available. Other domain links are limited because their implementations and route declarations were not sampled.

Main entry points: [`app/Services/OrderService.php`](https://github.com/codewithgeon/prodflow-role-managed-product-and-order-system/blob/main/app/Services/OrderService.php) (Order service), [`config/database.php`](https://github.com/codewithgeon/prodflow-role-managed-product-and-order-system/blob/main/config/database.php) (Application database), [`app/Services/Auth/AuthService.php`](https://github.com/codewithgeon/prodflow-role-managed-product-and-order-system/blob/main/app/Services/Auth/AuthService.php) (Auth service), [`app/Services/ProductService.php`](https://github.com/codewithgeon/prodflow-role-managed-product-and-order-system/blob/main/app/Services/ProductService.php) (Product service)
