source_id), and coverage is disclosed under exactly the
authority those rows are: a caller a relation’s read rule refuses for a
source’s rows is refused here for the same reason. The read participates in
dependency tracking like any other, so a result that concluded “we cannot
establish this” is reevaluated when the source’s coverage changes.
