Run ZSlayerWatchdog.exe. It automatically discovers SPT.Server.exe and reads its configuration from the Command Center config file.

The UI is a WebView2-rendered HTML frontend featuring a low-poly wolf head mascot flanked by server and headless status cards, with process controls, sliders, and toggle switches in a dark-themed layout matching the Command Center.

The watchdog reads and writes to the Command Center's config.json. All settings are editable from the UI — no manual config editing needed.

When Minimize to Tray is enabled:

• Clicking ✕ or — hides the window to the system tray
• Double-click the tray icon to restore
• Right-click for a context menu: Show Window, Open CC, Restart Server, Restart Headless, Quit

When disabled:

• ✕ quits the application (stops all managed processes)
• — minimizes to taskbar normally

The watchdog connects to the Command Center server via WebSocket for real-time bidirectional communication. Authentication uses a shared token (watchdog-token.txt) with automatic discovery.
