## Overview

DVLD is a WinForms licensing-department management system organized into presentation, business-logic, and data-access layers. Operators authenticate, then manage people and users, create and progress licensing applications through tests, issue or maintain licenses, and handle international permits and detention/release. The README documents the broader testing and enforcement capabilities; sampled code confirms application startup, service-form dispatch, license lookup, and BLL-to-DAL access. Most feature wiring is unsampled, so uncertain calls are not drawn.

Main entry points: [`DVLV/DVLV/Applications`](https://github.com/mrwnmoh/dvld/tree/main/DVLV/DVLV/Applications) (Application services), [`DVLV/DVLV/Main/Forms`](https://github.com/mrwnmoh/dvld/tree/main/DVLV/DVLV/Main/Forms) (Main workspace), [`DVLV/DVLV/Login/Forms`](https://github.com/mrwnmoh/dvld/tree/main/DVLV/DVLV/Login/Forms) (Login and settings), [`DVLV/BussneicsLayer/clsPerson.cs`](https://github.com/mrwnmoh/dvld/blob/main/DVLV/BussneicsLayer/clsPerson.cs) (People and identity)
