+## Physical Fremen Ambassador relocation — 8 October 2026
+
+The Ambassador expressly relocates a board force group. The normal
+Sandmaster movement band now optionally collects one spice at its entered
+destination, before arrival reactions. No intervening route is implied.
+Moving between sectors of the same territory earns none. The existing
+living native trainer, supported-profile and unique positive pile rules
+remain; concealed-marker relocation is still separate.
+
+`sandmasterDestinationCollection` is shared by this direct relocation and
+the existing worm adapter. Human controls expose a checked, optional
+destination collection choice; bots attach it only to an eligible physical
+relocation. Native quoting records the trainer and exact pile in
+`ambassadorSandmaster`, distinct from ordinary ground-route receipts.
+Suspended CHOAM movement revalidates that receipt through the original
+Ambassador event. Cancellation collects nothing; commit transfers one
+board spice once before the original arrival continuation.
+
+Basic and Advanced direct smokes cover collection, decline, same-territory
+and multiple-pile rejection. A bounded owned-destination Easy candidate
+reaches the real relocation engine. The adjacent native Advanced worm
+still transfers one spice and moves four forces. In Chromium, live React
+controls ran against the native engine: Basic collection produced
+spice21/board1, Advanced opt-out spice20/board2, both with destination2
+forces, unchanged ordinary allowances and completed Ambassador events.
+This is an isolated component/engine smoke, not HTTP or deployed acceptance.
+No broad suite or recovery campaign was run.
