## Executive Summary
A complete dependency audit was performed across all 28 QML components in `quickshell/` and 24 backend scripts in `scripts/`. 

- **System Binaries / CLI Utilities**: 35 cataloged | 35 installed (100% Complete)
- **Python Package Dependencies**: 1 external (`Pillow`) + stdlib | 100% installed
- **Qt / QML Engine Modules**: 8 cataloged | 100% installed
- **System Daemons & DBus Services**: 7 cataloged | 100% running & active
