+## Basic Ixian ally replacement with independent Ecaz cards — 29 October 2026
+
+In a supported Basic Richese/Ix game with the independent Ecaz Treachery cards,
+an allowed Ixian allied replacement now offers Semuta the discarded purchased
+card before the original replacement draw. The neutral offer keeps the face
+private until an eligible holder commits. Claim or pass preserves the paid sale
+and performs the original replacement draw once; an exhausted deck refills only
+after the reaction. The printed Semuta discard timing and existing private
+exchange interpretation are unchanged. The earlier Karama cost used to cancel
+replacement retains its prior independent-card behavior; other modules and
+unhandled discard parents remain outside this slice.
+
+[Native runtime](../tests/semuta-independent-ix-ally.test.ts) starts a public
+Basic game, acquires Semuta, forms the alliance at a real Nexus and pays for the
+original auction card. An exhausted-deck case explicitly rearranges existing
+physical cards after purchase. [Rendered controls](../tests/semuta-independent-ix-ally-controls.test.tsx)
+cover the neutral offer and claimant's private outcome.
