## Overview

This is a Laravel REST API for a school enrollment product, with MySQL persistence and a Flutter client described in the README. The main workflow is students browsing courses and schedules, submitting an enrollment, uploading course-payment receipts, and staff reviewing enrollment and payment status. Separate API areas support authentication, profiles, announcements, dashboards, and administrative management. The graph focuses on the backend because Flutter application source files are not present in the supplied tree; unsampled API capabilities are included where documented, with relationships limited to route references and sampled source evidence.

Main entry points: [`enrollment-sys-api/routes/api.php`](https://github.com/scheasa/enrollment/blob/main/enrollment-sys-api/routes/api.php) (API routes), [`enrollment-sys-api/app/Http/Controllers/Api/Concerns/ApiResponses.php`](https://github.com/scheasa/enrollment/blob/main/enrollment-sys-api/app/Http/Controllers/Api/Concerns/ApiResponses.php) (Shared API responses), [`enrollment-sys-api/app/Http/Controllers/Api/EnrollmentController.php`](https://github.com/scheasa/enrollment/blob/main/enrollment-sys-api/app/Http/Controllers/Api/EnrollmentController.php) (Student enrollment), [`enrollment-sys-api/app/Http/Controllers/Api/PaymentController.php`](https://github.com/scheasa/enrollment/blob/main/enrollment-sys-api/app/Http/Controllers/Api/PaymentController.php) (Receipt payments)
