## Current Phase: **Core Implementation Complete - Media Capture Next**

**Implementation Summary:**
- ✅ Complete server with SSL, authentication, database, messaging
- ✅ Complete Qt6 client with dark theme, chat, user list, status bar
- ✅ Networking with reconnect backoff and JWT sessions
- ✅ Windows installer template
- 🔄 Media capture stubs (Pipewire/FFmpeg/Portal integration needed)
- 🔄 Video streaming protocol (message types defined, handler needed)

**Next Steps:**
1. Install dependencies and test build on Linux/Windows
2. Generate SSL certificates for testing
3. Implement Pipewire camera capture
4. Implement screen capture backends (X11/Wayland/Windows)
5. Add video stream message types and server routing
6. Test end-to-end video streaming
