Ownership And Positions
Portal records can have an individual owner and a position owner.
owner_user_id is derived from the authenticated user when a record is created.
It should not be submitted from normal browser forms.
owner_position_id is optional and can be selected on owner-aware forms. It
allows users with the matching effective position to see or manage the record
when service-side authorization grants that scope.
Rows with no owner user and no owner position are legacy or unassigned records. They should normally be visible only to all-scope administrators until ownership is assigned.
