A.Buchanan: Since legality is a (minor) issue in setting up this position, can argue that retro concerns apply, hence DP rule. So the last move was not e6-e5, but must have been d6xe5+ or f6xe5+ with living alternative d5 or f5. So that would account for the last missing White unit (apart from the irrelevant White light-squared bishop). (2021-04-15)
