ReadonlymethodsThe methods the picker offers, in the answer's order.
Optional ReadonlypreselectedThe picker's preselected method, when its state names one; never the absent-default marker.
Optional ReadonlyselectThe selection QPL the picker issued for its action; absent when it issued none.
The method picker's issued values: the rows it offers, its preselected method and the QPL its selection action echoes. The login answer fetches them whenever it fetched the picker (always on a non-approve default; on the approve default only for a platform that asks for the picker up front).
