+**Advanced mixed-family paired arrivals — 29 October. Prototyped / Partial.**
+An Advanced native-faction table with Ecaz and Moritani can now retain both
+Ambassador and Terror opportunities when one movement enters their shared
+stronghold. CHOAM's prevention decision resolves before the original move;
+both owner decisions then follow the existing provisional storm order without
+repeating the move. Focused mixed-family fixtures exercise Tleilaxu, Ixian and
+Fremen movement, both owner orders, actual Robbery and Duke acquisition, and
+CHOAM prevention and cancellation. Six related offline files pass 118 cases;
+the existing unsupported saved-retry recovery case also passes. Type/lint and
+production build pass. Advanced Fremen and Guild Ambassador child arrivals,
+other module combinations, deployed acceptance and complete rules remain open.

+The existing paired-entry queue now also accepts Advanced games with Ecaz,
