 ## Validation and privacy
 
 Read, action and automatic recovery all verify one private fresh card receipt, exact custody, current turn/phase, matching removed token and source, seated former owner and Moritani, stronghold/sector, typed arrival counts, pre-discard hand size and the appropriate consumed stage.
