🔒 Security & Connection Details

• Rolling One-Time PIN: A fresh 6-digit PIN is generated upon startup and regenerated after each successful pairing or manual revocation.
• Brute-Force Protection: IP-based lockout triggers automatically after 5 consecutive incorrect PIN attempts (30-second escalating lockout).
• Bearer Token Authorization: Paired devices receive a cryptographically secure 48-character session token stored locally on your device.
• Dual Transport: High-frequency mouse coordinates and laser pointer positions stream over WebSockets for minimal latency, with automatic fallback to REST endpoints if required.
• Offline Self-Contained: Socket.IO client library and assets are fully bundled locally — no internet connection or CDN required.

⚙️ Configuration & Custom Presets

Key mappings are defined in presets.json. You can customize or add hotkeys for your favorite applications:

🖥️ Platform Support

Laser pointer note: Windows uses its native Tk overlay. Linux uses an X11 SHAPE 1.1 window with an empty input shape so mouse and touch events pass through. A direct Wayland session is not supported. XWayland availability depends on its display exposing SHAPE 1.1; if initialization fails, the app reports the pointer unavailable and keeps the laser pad hidden. macOS support is not yet implemented.

🧪 Running Tests

# Python backend tests (82 tests)
pip install -e ".[dev]"
pytest

# Frontend unit tests (17 Vitest tests)
npm install
npm test

Tests run automatically on Linux, Windows, and macOS via GitHub Actions.
