Reproduce it, then close it. Run ./hints/repro/BUG-06.sh with a stock update and watch the shelf drift below what exists. Then fix cancel so the portion comes back — and notice that you can only write this now, because tonight somebody finally decided what should happen. Anna Madam answered it in a queue, out loud, in the way she answers everything: if the kitchen hasn't started it, it goes back on the shelf; if they have, it goes to the next person and nobody pays twice. That is the sentence you have been missing since Episode 4. Now re-enable the test you disabled in Episode 37 and run the suite. It goes green. That test has been sitting in your repository for five episodes waiting for a human being to make a decision, which is exactly what it was for.
