+## Advanced native Ambassador child arrivals — 29 October 2026
+
+**Prototyped / Partial.** In the bare Advanced native-faction profile, the
+Fremen Ambassador relocation and Guild Ambassador shipment can now create a
+child arrival while the original paired Ambassador/Terror entry remains in
+progress. The existing child-first continuation preserves the original entry,
+remaining opportunity and physical movement or payment. A positive Sneak
+Attack in this overlap queues its own reactions until the original decisions
+finish, including its Bene Gesserit opportunity. The owners' storm order and
+child ordering remain the provisional software interpretations below, not an
+official priority ruling; the printed Ambassador effects and interruption are
+described in GF9 Ecaz & Moritani rules pp. 8 and 15.
+
+Fremen destinations combining Advanced fighter Intrusion with Terror retain
+their existing restriction, and simultaneous Ambassador/Terror on Guild
+accompaniment remains separate. Other optional modules, Advanced Sneak outside
+this overlap, complete rules and deployed verification remain open.
+
+Eight related files pass 52 cases. Real Advanced setup covers both owner orders,
+Fremen and Guild child effects, child Terror decline or reveal, the paid original
+entry, the free Guild grant, controls and legal existing bot choices. A separate
+Advanced Sneak/Bene Gesserit case verifies that the original Terror decision
+finishes before accompaniment. Fixtures control original token selection and
+placement; the separate child Sneak token is staged.
