The subprocess stdout was a pipe to the TUI. When the TUI exited, the pipe broke (SIGPIPE) and killed the backup process. Now the subprocess writes to a log file in WORK_DIR, and the TUI tails it for live display. When the TUI exits, the subprocess keeps running because it writes to a file, not a pipe. On restart, the log file is loaded to show output for reconnected or finished background jobs. Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
