Frontend:
- trace empty-state now shows connection status + capture mode (boxed,
colored) in the center, updated live via checkConnection
- capture-mode uses amber warning style (gsmtap/disabled), green for direct
- stopCapture clears currentSessionId
Server:
- gsmtap read_packet catches OSError on socket close (no more EBADF
traceback on stop)
- stop_session joins the loop and discards a session with zero messages;
/api/capture/stop reports discarded
- startup prints server version
Tests: 122 (gsmtap close, empty/non-empty capture lifecycle).
