No downstream edge has cleared review for this node. This is a graph-coverage statement, not a claim that the historical form produced nothing.

“Every” means every descendant in the reviewed SET-U graph. It does not convert missing scholarship or missing ingestion into a claim of historical completeness. The coverage ledger remains the honest denominator.
