Attribute	Type	Required	Description
personaId	string	Yes	Who sits in. A host; a caller or a guest who drops by can never present a show
days	number[]	No	The nights they present, by the weekday the night begins on, Sunday 0. Send this or everyN, not both
everyN	number	No	Or at random: about one of this slot's nights in this many, on nights nobody can predict. 7 is about one in seven
cooldownDays	number	No	With everyN, the fewest days between two of their nights. Absent is half of everyN, so even one in seven never lands two nights running
