## Overview

This is a CodeIgniter 4 distribution containing both the framework runtime and a cash-management application. The app’s visible workflow includes authentication, request/approval handling, cash-balance updates, and file/report handling. The web entry point and routing are documented or indexed; the sampled FileController excerpt shows several model interactions. Other application stages and framework services are represented from the tree and framework identity, but unsampled wiring is left unverified rather than asserted.

Main entry points: [`app/Controllers/FileController.php`](https://github.com/vin0414/online-petty-cash-monitoring/blob/main/app/Controllers/FileController.php) (Cash Operations), [`system/CodeIgniter.php`](https://github.com/vin0414/online-petty-cash-monitoring/blob/main/system/CodeIgniter.php) (Request Runtime), [`app/Config/Routes.php`](https://github.com/vin0414/online-petty-cash-monitoring/blob/main/app/Config/Routes.php) (App Routes), [`public/index.php`](https://github.com/vin0414/online-petty-cash-monitoring/blob/main/public/index.php) (Public Entry)
