/**
 * When to hand a submitted plan to the human (the Accept / Feedback / Reject
 * box).
 *
 * The box must open only once nothing else will act on the plan: the run that
 * submitted it has fully settled (an Accept during the run's tail is refused
 * with 409), no new run is starting, and no autopilot cycle (Ken) is still
 * deciding. Every way Ken can stop without approving — handing the plan back,
 * a failed review, the round cap, a Stop, a skipped cycle — leaves the plan
 * pending, so this one check covers them all. Offers are once per plan
 * generation so repeated settle points don't re-open a box the user just
 * closed.
