+
+That state — anchors derived, nothing left unanchored, no page naming any of them — used
+to end the headline in a ✅. It no longer does (#11356). The sentence reports the **naming

+`min`/`max`) — the run derived 9 anchors, matched 0 pages, and rendered the ✅, while

+that would catch it is escalated as #11817. What the narrowing changes is that the run no
+longer **claims** it did — the verdict states only what it measured, and the clean-bill
+glyph is left to a run that earned one. The rendering is pinned in both directions by
