The server this process is running inside.

tmux exports TMUX to everything it starts, as `<socket path>,<server pid>,<session id> Only the socket path is read: the session id is stale the moment a pane moves, and a#()` job carries no session at all — so a caller who wants the session asks tmux, rather than trusting what it inherited.
