## Overview

This is a CodeIgniter 4 EMKL operations and internal-approval application. Users authenticate, enter operational requests or open approval grids, review records through server-side AJAX, and submit approval or rejection actions. The documented domains include Trip, PO, Pengajuan, Absensi, extra-driver, and price-offer approvals, plus trucking-related operations. Services mediate controller workflows and grid processing; models access SQL Server data. The graph follows documented routes and sampled/indexed references. Several domain implementations and views were not sampled, so their internal calls are not inferred.

Main entry points: [`app/Config/Routes.php`](https://github.com/luhur65/emkl-approval/blob/main/app/Config/Routes.php) (Route map), [`app/Controllers/ApprovalTrip.php`](https://github.com/luhur65/emkl-approval/blob/main/app/Controllers/ApprovalTrip.php) (Trip controller), [`app/Controllers/Pengajuan.php`](https://github.com/luhur65/emkl-approval/blob/main/app/Controllers/Pengajuan.php) (Driver request entry), [`app/Services`](https://github.com/luhur65/emkl-approval/tree/main/app/Services) (Approval services)
