The E-1608 source marks every restart as lost and logs each overrun; its form stops touching siblings after the chooser destroys them; the link skips command id 0, retries a full-buffer discover send and ignores a zero-length scan read. Session files escape \n and \r; get_int and get_double reject out-of-range values; the UDPS port spin reports changes; a skipped source panel says why on stderr. The E-1608 probe now checks the signal names and the reconnect itself. Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
