 # Semuta Drug source update and implementation boundary
 
+## Basic Terror discards during a worm ride — 29 October 2026
+
+**Prototyped / Partial.** A native Fremen worm ride into Sabotage or Robbery
+can now offer the victim's random Sabotage discard, a subsequent Sabotage-gift
+overflow, or Moritani's Robbery-draw overflow to Semuta. Each private discard
+has its own original continuation; the gift or draw is not repeated, and the
+remaining worm queue resumes once. The queue is bound to the saved reaction.
+The focused fixture uses real setup, placement and riding, and stages conserved
+cards and a second ride to exercise the gift and queue. Paired Ambassadors,
+summoned worms and other nested parents remain guarded; ordering is an online
+interpretation, not a new publisher ruling.
