Wave 5 · The review and the return

The person's decision is a fact like any other, and the machine acts on it once. The Cell is sealed, its answer leaves it, and it comes back into the slot that opened it — as a note.

   The person reviews the Cell and accepts it. The decision comes to the door as a fact, so a new wave starts.

   The wave ends. The run closes as the first fragment's did — with a release nothing listens to — and between the two endings, a whole Cell.
