+🔴 **My first correction of this section was itself wrong, on all three clauses,
+and is replaced (2026-08-30).** It read: *"The two items this section named are
+UNBLOCKED, not answered … Both need a running menu, both now have one, and neither
+has been attempted."* I wrote that without reading either page. Reading them:

+* **`8AX` vs `ptbase` was RESOLVED on 2026-08-29.** Its page says so in its status
+  line — both its questions closed, kept for the evidence.

+  [tone curve](../re/structures/ui-render-tone-curve.md)
+* **So neither ever needed a running menu**, and this section's premise was wrong

 The original section is kept below for the record, demoted so it cannot be read as
 current.
