org.cairnsproto.draft.listDraws

Sites a sponsor holds a deliverable draw for: the newest epoch whose retrace window is still open and whose beacon draws the sponsor, for sites not yet past their export bar, in projects where the declared model counts, where the sponsor is eligible and the draw hash falls under the escalated threshold. Each draw carries what a client needs to verify it and do the work. Course-0 sites nobody has opened are listed separately under open, since a first read needs no draw.
