onDeleted

whether the command is decided on a deleted aggregate too, as RestoreAggregate is: a command that restores it, producing AggregateRestored beside its own events, or one a deleted aggregate still takes. Every other command is refused on a deleted aggregate. Such a command produces AggregateRestored and its aggregate's own events alone. False by default.

A command changes the aggregate's lifecycle by producing the lifecycle event beside its own events, in one commit: CloseCart(reason) produces CartClosed(reason) and AggregateDeleted; the kernel then marks it deleted, as DeleteAggregate does. Deciding the same event twice changes nothing more; a command that would change nothing returns Decision.NoOp.
