║            QUASAR WebSocket Test Tool v1.0                     ║
╚════════════════════════════════════════════════════════════════╝

USAGE:
    # Monitor what hub is broadcasting (metrics from all spaces)
    python3 test_websocket.py --subscribe
    
    # Send a test metric to hub (publish as a space)
    python3 test_websocket.py --publish --space TEST_ASSET
    
    # Send test metrics with a different space name
    python3 test_websocket.py --publish --space V100_1h

EXAMPLE WORKFLOW:

  Terminal 1 (Monitor hub):
    $ python3 test_websocket.py --subscribe
    [✓] Connected! Listening for metrics updates...

  Terminal 2 (Send test data):
    $ python3 test_websocket.py --publish --space V100_1h
    [✓] Connected! Sending test message...
    [✓] Sent:
    {
      "training": {...},
      "voting": {...}
    }

  Terminal 1 (should see the message):
    [12:34:56] Message #1:
    {
      "space_name": "V100_1h",
      "training": {...},
      "voting": {...}
    }

TROUBLESHOOTING:

  "Connection refused" → Hub not running on port 7860
    $ curl http://127.0.0.1:7860/api/health
    
  No messages on subscribe → Asset spaces not connected
    Check if asset spaces are running and sending data
    
  "Module not found: websockets" → Install it
    $ pip install websockets
