| 제목 | SSH consumed the tmux send-keys argument boundary |
|---|---|
| 궁금했던 점 | Why did a quoted tmux launch command arrive without spaces on the remote B200 shell? |
| 해본 것 | The launcher invoked remote tmux send-keys through SSH with the full experiment command intended as one quoted argument. |
| 당시 조건 | B200-2 sequential migration launch at source commit 038c9cd00c25fc83678d4d698f8780bfc5d96369. |
| 실제 결과 | 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. |
| 왜 그랬는지 | 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. |
| 다음에 기억할 것 | 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. |
| 언제 맞는지 | Applies to detached remote experiment launchers that drive tmux through nested local and remote shells. |
| 신뢰도 | 중간 |
| 관련 자료 | Pane command-not-found at 2026-07-17; no global lock owner, no run directory, and zero B200 compute processes. |

The pane showed a concatenated command token and command-not-found. Immediate checks showed no global lock owner and no GPU compute application; the append-only run ID remained unused.
