## How It Works

1. Tauri starts → spawns `batchtube-server` sidecar (PyInstaller bundle)
2. Rust polls `http://localhost:8765/api/health` every 500ms
3. When server ready → shows webview window loading `http://localhost:8765`
4. User sees the existing BatchTube web UI inside a native window
5. On close → Tauri kills the sidecar process

## Build

### Prerequisites
- Rust (stable)
- Node.js 22+
- Python 3.11+
- PyInstaller: `pip install pyinstaller`

### Development
```bash
# Start Python backend first
cd backend && python api_server.py &
# Then start Tauri dev mode
npm run dev
```

### Production Build
```bash
# Bundle Python backend
cd backend && pyinstaller batchtube-server.spec
# Build Tauri app
npm run build
```

### Cross-Platform (CI/CD)
Push a tag `v1.x.x` to trigger GitHub Actions build for:
- Windows (.exe + .msi)
- macOS (.dmg — Intel + Apple Silicon)
- Linux (.AppImage + .deb)

## Rollback Plan

If Tauri build fails at any point:
```bash
bash rollback.sh
```
This reverts to the `v1.0-pre-tauri` git tag.
The original NSIS Windows installer remains at `BatchTube App/BatchTube-Windows-Build.zip`.

## Pricing Integration

License validation happens at app startup via `http://localhost:8765/api/license`.
ThriveCart webhook at `https://n8n.intentures.org/webhook/thrivecart` handles purchase events.
