+Storm relocation and Advanced Ixian special Karama now offer one Sandmaster
+debit pile per entered territory, or an independent decline of that bonus.
+The global collection opt-out still declines all collection. The shared
+quote requires a living native Ixian trainer and actual interior passengers.
+Explicit `sandmasterPiles` declarations preserve the exact chosen keys
+through native cancellation and special-Karama preparation/reconstruction.
+Ambiguous undeclared or duplicate-territory selections reject before cost.
+
+Sandmaster debits first, then the unchanged native collection uses the
+traversed sectors and two-spice-per-passenger cap. The route preview follows
+the same order, including repeated sector visits. With six passengers,
+Arsunt11 holding12 and Arsunt12 holding5, choosing11 earns12 total;
+choosing12 earns13, leaves Arsunt12 at4 and drains Arsunt11. Native
+cancellation moves neither pointer nor spice. Older queued moves without
+the new selection retain their original unambiguous-pile behavior.
+
+Owner sector allocation is provisional, not publisher adjudication; the
+7 October user eligibility/order ruling is unchanged. Basic/Advanced
+native smoke, selected-key JSON continuation, cancellation, all four legal
+policies and a labelled Advanced special-Karama seam pass. At390px,
