Twenty-five minutes in, the session is good and you have stopped checking it as closely as you did at the start. You roughly know what you decided and you roughly know what is still open. What you do not know is what got filled in on your behalf, because the work could not proceed without it and you had not said. Those are load-bearing and none of them was a decision. 17 prompts for stopping mid-session and asking for three lists, decided, open and assumed: the sorting rules that keep a stated choice out of the assumed column, the pass that attaches a consequence and a two-minute check to every assumption, the push for when the third list comes back short, and the strike for the flattery that pads it. The third list is the session you are actually in.
