In all cases, you may assume that the position was arrived at via a sequence of legal moves from the starting position (i.e. from the only legal starting position), and there have been no irregularities, such as incorrect starting position, illegal moves, pieces being displaced and incorrectly replaced, pieces magically materializing out of nowhere, pieces magically disappearing, illegal promotions, etc.
