/**
 * The frontend half of the `waiting_reason` shape contract (#3074).
 *
 * The scheduler encodes "starts by itself" as a reason made only of `Busy: ...`
 * clauses, joined with ` | `, and decides notifications on that basis. The UI
 * reads the same bit to decide what still belongs on a forecast. These cases
 * are the exact strings both branches of the scheduler emit, so a reword on
 * either side lands here first.
