 # Juice of Sapho: finite ordering implementation
 
+## Shared Ambassador and Terror arrival — 29 October 2026
+
+**Prototyped / Partial.** In a supported fresh Basic Richese game, an ordinary
+shipment or movement that triggers both an Ecaz Ambassador and Moritani Terror
+opens a public ordering opportunity before either reaction. Each original owner
+can continue; an owner holding an eligible physical Juice of Sapho can place
+its own reaction first or last. The existing provisional storm order starts
+the queue. Both owners respond independently of their hands, preserving hidden
+card ownership. Sapho disposal opens the normal neutral Semuta response and
+then returns to the same ordering opportunity or opens the selected first
+reaction. Entry, payment, forces and both original tokens remain committed once.
+
+This is a provisional composition of the printed Sapho effect with the
+existing provisional overlap order, not a publisher ruling. The current
+prototype is limited to ordinary Basic movement/shipment, the existing bare
+Semuta profile, and clean arrivals without other queued or nested transport.
+Earlier saved overlaps without an ordering frame keep their original behavior.

+The provisional Basic overlap procedure offers Ecaz and Moritani a public
