+**Prototyped / Partial.** A fresh Basic Richese game with the CHOAM deck,
+classic or CHOAM peers and Nexus Cards now initializes the existing Semuta
+protocol. Public setup still requires a qualifying Nexus and actual alliance
+before a player can draw. CHOAM Secret Ally trade and CHOAM Betrayal retain
+their original costs and offer their eligible discard; claim or pass resumes the
+original effect. Simultaneous Truthtrance Sapho ordering likewise resumes the
+same questions. Emperor Secret Ally's extra revival and ordinary bank-auction
+purchase remain available, and a completed Truthtrance during the bank payment
+can offer Semuta before restoring that original invoice.

+have genuine audit-start journeys with staged positions, cards and Nexus
+identity. The ordering combines existing printed effects and the project's
+provisional reaction convention; it is not a new publisher ruling. Advanced,

+complete games and deployed acceptance remain open. Existing games are not
