Name	Type	Description
cause	CommandCause	The command that caused it, command.cause, from the command’s reader or a later system that kept it: the room tells the command’s sender alone, whose page reads the event’s cause as her request id, and no other page learns who acted.
effect?	string	The key of the predicted effect the command’s reader played on her page, which this event confirms, such as "cast": her page reads it as the event’s effect.
