+## Printed Kull in supported Basic starts — 27 October 2026
+
+Offer an explicit lobby opt-in for the existing printed Kull response in fresh
+Basic CHOAM/classic starts with the CHOAM and Ix decks and no optional modules.
+The default remains off; the preview visibly discloses unavailable structured
+Truthtrance commitment families and the user-deferred unfunded non-CHOAM winning-overbid
+fence. Retain the selected distinct counter and reserved original attempted
+card. The publisher's Basic rule establishes the reaction, while the nested
+protocol and fence retain their recorded policy status. Nexus fuel, other
+compositions and existing saved games remain under their existing boundaries.
