Assign a mandate to a household

A standing assignment: an objective, pinned constraints (a profile { id, version } or literal assumptions, never an implicit default) and an approval policy. Lodestar works it when a deadline approaches, the household changes, rules or your assumption profile change, a scheduled review comes due, or on request, and files proposals for an approver. One mandate per type per household until it ends. Each cycle's sweep counts the household as active for the month.
