+## Native Ecaz ordinary-disc composition — 4 October 2026
+
+Fresh local `leader-skills` now admits Basic/Advanced native Ecaz with classic
+opponents, the exact `ecaz` family and all fourteen physical skills. Basic
+Harkonnen remains permitted; Advanced Harkonnen keeps the original shared-Duke
+capture boundary. Public starts, other factions/modules and combined Occupy
+skill battles are not opened. Skill assignment uses the five native discs,
+never the separately controlled Duke. Source-ordered starting cards, public
+skills, Loyalty/Traitors and original six-force placement remain genuine.
+
+Ordinary native role scores, physical Suk rescue and trained-disc death compose
+with original handlers. Eligible own normal-disc revival through paid first
+cohort or a physical Ghola retains optional decline/draw/assignment. Native
+Ambassador placement, bank grants and original entrant continuation preserve
+training. Explicit Mentat and separate Banker opt-ins retain current questions;
+an Ambassador bank grant is not another player's bank payment.
+
+Real Ecaz Ambassador acquisition gives one temporary Duke6. A separate living
+face-up native Warmaster adds only its normal1 with a physical Worthless card,
+never trained-disc3. Surviving release and actual poison death preserve native
+trainer/card; bounty is printed6. Ecaz's original paid5 revival returns the
+same living set-aside disc under the user's earlier ruling. These cases retain
+an existing native skill and do not settle shared-Duke skill assignment.
+
+Focused9/9 and twenty actual controlled programs pass: Basic/Advanced Duke

+actual native Banker payment. Ten genuine Basic/Advanced two-through-six-seat
