## Overview

GLPI is a web-based IT asset and service-management system. Users access its web interface to manage assets, submit and work service requests, and use related knowledge, planning, and administration features; the README documents these product capabilities, while the sampled web entry point names the application kernel. Domain modules cover assets, ITIL work, forms, knowledge, and supporting management functions, with shared persistence, session, and rendering layers. The graph combines documented capabilities with sampled runtime links; unsampled subsystem wiring is intentionally not asserted.

Main entry points: [`src/Glpi/Form/Form.php`](https://github.com/presley-rocha/glpi/blob/11.0/bugfixes/src/Glpi/Form/Form.php) (Form management), [`src/Glpi/Kernel/Kernel.php`](https://github.com/presley-rocha/glpi/blob/11.0/bugfixes/src/Glpi/Kernel/Kernel.php) (Application kernel), [`src/Glpi/Controller/Form/Condition/EngineController.php`](https://github.com/presley-rocha/glpi/blob/11.0/bugfixes/src/Glpi/Controller/Form/Condition/EngineController.php) (Condition endpoint), [`src/CommonDBTM.php`](https://github.com/presley-rocha/glpi/blob/11.0/bugfixes/src/CommonDBTM.php) (Common item persistence)
