 * Takes an available update, inside the window, if the owner asked for that.
 *
 * It leaves exactly the same request the button leaves — same file, same agent,
 * same run. There is no second path into a deployment, because a second path is
 * a second set of rules to keep in step with the first.
 *
 * Nothing here checks whether an update already ran today. It does not need to:
 * an installation that is current has nothing available, so an operator who
 * pressed the button at four finds the five o'clock window with nothing to do.
