public boolean isPartial() {
    return partial;
  }
If {@link #partial} is false, returns state from the bitmap. If no state is found for
{@code procId}, returns YES. If partial is true, tracker doesn't have complete view of system
state, so it returns MAYBE if there is no update for the procedure or if it doesn't have a
state in bitmap. Otherwise, returns state from the bitmap.
