## Overview

This Symfony application supports employee training requests (LDRF), approval, post-training evaluation, and HRO training oversight. The principal workflow is request submission and tracking, followed by approver review and notification; completed training can then be evaluated and reported. Separate branches cover training inventory/monitoring, needs analysis, user and department administration, and security. The excerpts confirm selected controller, repository, and service interactions; several listed controllers and services were not sampled, so their internal wiring is intentionally not inferred.

Main entry points: [`src/Controller/LdrfController.php`](https://github.com/aeronsal/feu-das/blob/feu-das/src/Controller/LdrfController.php) (Training requests), [`src/Controller/TrainingNeedsAnalysisController.php`](https://github.com/aeronsal/feu-das/blob/feu-das/src/Controller/TrainingNeedsAnalysisController.php) (Needs analysis), [`src/Controller/FixedApproverController.php`](https://github.com/aeronsal/feu-das/blob/feu-das/src/Controller/FixedApproverController.php) (Approval actions), [`src/Controller/NotificationController.php`](https://github.com/aeronsal/feu-das/blob/feu-das/src/Controller/NotificationController.php) (Notification access)
