## Overview

This repository is a Symfony JSON REST backend for user, group, role, and API-key management, with authentication, localization, health checks, and request/login logging. The main workflow is a client request entering a controller, using REST/resource and persistence layers to work with domain entities, then returning a serialized response. The tree and excerpts show this structure, but many routes and services were not sampled; edges are limited to relationships supported by excerpts, the source index, or README statements.

Main entry points: [`src/Controller/v1/UserGroup/AttachUserController.php`](https://github.com/tarlepp/symfony-flex-backend/blob/master/src/Controller/v1/UserGroup/AttachUserController.php) (User Group Attach), [`src/Controller/HealthzController.php`](https://github.com/tarlepp/symfony-flex-backend/blob/master/src/Controller/HealthzController.php) (Health Endpoint), [`src/Rest/Controller.php`](https://github.com/tarlepp/symfony-flex-backend/blob/master/src/Rest/Controller.php) (REST Controller), [`src/Repository/UserRepository.php`](https://github.com/tarlepp/symfony-flex-backend/blob/master/src/Repository/UserRepository.php) (User Repository)
