## 📝 Implementation Checklist

### Backend (Complete ✅)
- [x] OpenClaw on localhost
- [x] Proxy service created
- [x] Proxy running on port 18790
- [x] Windows firewall opened
- [x] HAProxy configured
- [x] Authentik OAuth provider created
- [x] DNS resolves (wildcard)
- [x] SSL configured

### Android App (To Do)
- [ ] Add AppAuth dependency
- [ ] Create OAuthConfig
- [ ] Implement AuthManager
- [ ] Create OAuthCallbackActivity
- [ ] Update AndroidManifest
- [ ] Create LoginScreen
- [ ] Update MainActivity with auth flow
- [ ] Test OAuth flow

---

## 🧪 Testing Steps

### 1. Test Proxy Health
```bash
curl http://localhost:18790/health
# {"status":"ok","service":"alfred-proxy"}
```

### 2. Test HAProxy Connection
```bash
ssh root@192.168.1.20 'curl -s http://192.168.1.169:18790/health'
# {"status":"ok","service":"alfred-proxy"}
```

### 3. Test OAuth Flow (After Android implementation)
1. Open app
2. Tap login
3. Browser opens
4. Login with Authentik
5. Redirect back to app
6. Check logs: `adb logcat | grep AuthManager`

### 4. Test WebSocket Connection
1. Login to app
2. Check connection indicator (should be blue)
3. Send test message: "Hello Alfred"
4. Check proxy logs: `journalctl --user -u alfred-proxy.service -f`
5. Check OpenClaw logs: `journalctl --user -u openclaw-gateway.service -f`

## 🔐 Security Notes

1. **OAuth tokens are secure:**
   - Stored in Android SharedPreferences (MODE_PRIVATE)
   - Never exposed to OpenClaw
   - Validated by proxy on every connection

2. **OpenClaw token is secure:**
   - Only stored on desktop (proxy .env)
   - Injected server-side by proxy
   - Never sent to mobile app

3. **Connections are encrypted:**
   - HTTPS for OAuth (auth.dnspegasus.net)
   - WSS for WebSocket (alfred-app.dnspegasus.net)

4. **Revoke access:**
   - Disable user in Authentik → instant access loss
   - No need to change OpenClaw token

---

## 🚀 Next Steps

1. **Implement OAuth in Android app**
   - Follow `OAUTH_SETUP.md`
   - Test login flow

2. **Implement WebSocket connection**
   - Follow `WEBSOCKET_INTEGRATION.md`
   - Test chat

3. **Add features:**
   - Voice input
   - Lists, timers, notes
   - Push notifications

4. **Production readiness:**
   - Install proxy as systemd service
   - Set up monitoring
   - Configure logging
   - Test error scenarios

---

## 💡 Tips

**Android Development:**
- Use `adb logcat` to debug
- Test on real device (OAuth doesn't work well in emulator)
- Check browser is installed on device

**Proxy Debugging:**
- Watch logs: `journalctl --user -u alfred-proxy.service -f`
- Test health: `curl http://localhost:18790/health`
- Check OpenClaw: `wscat -c ws://127.0.0.1:18789`

**OAuth Troubleshooting:**
- Verify Client ID matches exactly
- Check redirect URI in Authentik
- Test token: `curl -H "Authorization: Bearer TOKEN" https://auth.dnspegasus.net/application/o/userinfo/`
