## Overview

This is an Android Jetpack Compose app for recording and reviewing rack inspections. The user enters through a splash/login flow, then navigates among rack entry, camera, records/history, and profile screens; rack records are managed through a ViewModel, repository, and Room persistence. The graph preserves the user/profile data and navigation subsystems shown in the tree, though the user ViewModel is commented out in the activity wiring. Several screen implementations were not excerpted, so their internal behavior is not inferred.
