|title=<nowiki>SSH consumed the tmux send-keys argument boundary</nowiki>
|question=<nowiki>Why did a quoted tmux launch command arrive without spaces on the remote B200 shell?</nowiki>
|attempt=<nowiki>The launcher invoked remote tmux send-keys through SSH with the full experiment command intended as one quoted argument.</nowiki>
|context=<nowiki>B200-2 sequential migration launch at source commit 038c9cd00c25fc83678d4d698f8780bfc5d96369.</nowiki>
|observation=<nowiki>The remote pane received a single concatenated token such as exec.venv/bin/python-mscripts..., returned command-not-found, and remained at an idle bash prompt. No global lock, run directory, or GPU compute process was created.</nowiki>
|interpretation=<nowiki>Local quoting did not survive SSH's remote command reconstruction as a single tmux argument. tmux then concatenated multiple send-keys string arguments without inserting spaces.</nowiki>
|reusable_lesson=<nowiki>For tmux send-keys through SSH, do not assume local one-argument quoting survives. Encode separators explicitly as tmux Space key tokens or preserve quoting inside the remote command string, then immediately verify the pane, lock owner, run directory, and GPU state.</nowiki>
|applicability=<nowiki>Applies to detached remote experiment launchers that drive tmux through nested local and remote shells.</nowiki>
|confidence=<nowiki>high</nowiki>
|evidence=<nowiki>Pane command-not-found at 2026-07-17; no global lock owner, no run directory, and zero B200 compute processes.</nowiki>
