+In the supported Basic native Ix/CHOAM roster, Richese may also reveal its
+existing marker while another faction's ordinary movement awaits a Fremen or
+Ixian movement response or a CHOAM movement decision. The original physical
+movement, source and reaction remain pending. Reveal places the available
+forces or removes a zero marker; it does not count as a movement or replay the
+original move. The implementation checks the selected foreign forces and
+retains its existing current-turn Truthtrance and commitment boundaries.
+Special movement parents and other optional modules remain outside this slice.
+This interrupt order is a provisional online interpretation.

+## Basic Ambassador discards during a worm ride — 29 October 2026
+
+**Prototyped / Partial.** A native Fremen worm ride into a CHOAM or Ixian
+Ambassador, including a Bene Gesserit copy, can now offer the original private
+discard group to Semuta. CHOAM's credit remains committed; an Ixian replacement
+is drawn once after the reaction. The original ride and remaining Spice Blow
+queue resume once, with the queue bound to the saved discard continuation.
+This covers the clean Basic profile; overlapping Terror, summoned worms and
+other parent interactions remain guarded. The ordering is an online
+interpretation of the printed fresh-discard timing, not a new publisher ruling.
