cart says do not convert while someone is mid-thought, ask whether they are ready, and say so if you convert anyway. I asked and got approval of a plan, which is not the same as having nothing left to write — so the check passed and was still wrong. Reported upward: are you ready to convert and is there anything you are still writing are different questions, and only the second would have caught it.
