+## Group Fremen worm protection — 29 October 2026
+
+**Staged Basic prototype, not a selectable game mode.** When a worm threatens
+either or both of Fremen's group allies, Fremen decides separately for each
+threatened ally in storm order. Each accepted protection has its own Karama
+response; the worm resolves only after all those choices and Fremen's separate
+survival response finish. Canceling one protection does not erase another.
+The choices bind the original worm event and ally, and the existing force
+loss, spice removal and continuation occur once. Controls name the current
+ally and minimal bots make the same legal choices. The printed single-ally
+power does not specify this multi-ally sequence, so its order and separate
+responses are provisional. Advanced, expansions and optional modules remain
+outside this staged path; group games are not yet available from the lobby.
