> In my personal setup, tmux server runs under `systemd --user`, outside of any defined session

Slight correction: `systemd --user` is not outside of any defined session — it does, in fact, run under its own logind session (of class "manager"). But that does not materially change what I said (it's still not the session that owns seat0).

Ah, you're right. Polkit explicitly asks logind for the user's current "display" session if a session can't be identified for the process.

Perhaps it shouldn't do that, since it thwarts any attempt by that process to provide a fallback agent (which all the systemd tools do when they're using polkit).
