Under the 8 October Basic-first prototype instruction, Basic now provisionally uses the main p8 paragraph: ceiling contribution/loss and floor survivors, with a visible control warning.

+## 17 October 2026 — Native World Ecaz Arrakis coalition
+
+The existing native World occupation and World/Skills setups could deal Ecaz
+but still rejected the mandatory allied Arrakis battle. Fresh Ecaz/classic
+World compositions now reuse the ordinary coalition instead of requiring Nexus
+Cards; the original World occupation entry also marks Basic participation.
+World locations remain outside Occupy/Intrusion. No army merger, new support
+rule, World loss adapter, played-game conversion or numerical ruling is added.
+
+Genuine setup, original worm alliance and native paid shipments put Ecaz4,
+Emperor4 (two Sardaukar) and Guild2 into a clear Arrakis stronghold. Both leads
+retain fixed Ecaz losses, exact allied normal/starred losses and unchanged
+native World custody. Advanced Salusa and paid ordinary support compose through
+the original physical quote; native Karama keeps the lead and excludes its
+co-side. The existing Skills disclosure/lead controls and four legal policies
+reach original Collection. Only unopened Spice order is controlled.
+
+The affected eight-file union **91/91**, types/lint and build pass; four separate
+runtime smokes reach Collection without rejected actions. Actual390px Ecaz
+World+Skills normal-lobby start reaches the real skill offers with no app errors
