 # Richese Ornithopter: movement integration audit
 
+## Imperial Homeworld movement — 27 October 2026
+
+E3printed10 permits Advanced Emperor to use its Movement between Kaitain and
+Salusa; supplied Advanced physical22/printed20 explicitly calls it Force
+Movement of any number of own forces. The recorded physical card grants two
+normal movements with different forces. Under standing recommended-option
+authority, provisionally compose them: either group may be an independently
+legal Imperial transfer or ground move, in either order; both may be transfers.
+Normal and Sardaukar cohorts remain distinct across all three stores.
+
+Homeworlds are not territories. Range3 grants no route or range to them; spending
+its replacement entitlement on the independently permitted Imperial transfer is
+a separate explicit provisional composition. Targeted GF9/designer searching
+found no dedicated combined answer. The earlier photographed card contract is
+retained; its old crop was unavailable, so no fresh card-face reread is claimed.
+Native route permission and Homeworld Karama immunity stay (E3p10); no shipment
+or spice cost is added. Moving first retains the native passed-shipment rule.
+
+Fresh Imperial flights stamp `homeworldCohort:true` and snapshot actual typed
+board and native-World custody. Arriving moved counters never increase remaining
+quotas. An older unstamped active flight was created while World transfers were
+blocked; the selected compatibility interpretation treats its then-untouched
+native World pools as unmoved, without rebuilding its recorded board cohort.
+That inference is not historical-save certification. No reserve total creates a
+World force. An uncompleted first attempt needs no cohort until an actual first
+group commits; its current card event may use the native transfer once controls
+are clear.
+
+Both groups completing earns one existing extra-move credit; early ending earns
+none. A later actual Hajr has its own allowance and may reuse moved counters.
+Final World movement uses a distinct `homeworld` discard continuation, binds
+the actual World custody and discards the original card once without an Arrakis
+arrival replay or automatic turn end. Ground-final disposal retains its native
+arrival continuation. The Imperial panel and shared legal AI adapter expose
+both modes/current continuation with provisional guidance and typed maxima.
+Broader modules, native Semuta reaction journeys and full acceptance remain open.

+Original Hajr is actually dealt when selected. World→ground, ground→World,

Both modes retain original event/cohort accounting. One unused normal/Hajr entitlement can start a flight; completed two-group credit preserves unused Hajr afterward. Each genuinely recovered Hajr replay has its own grant. Advanced uses supplied immediate-after-play timing with an explicit online/card-group convention. Both modes now accept Advanced advisors through native stance/entry and original-group rules. Advisors do not grant city access; current fighter-city range is recomputed for each normal group. Guild Cunning now retains actual earlier credits and permits a physical card to replace an unused Hajr grant, with active-flight and early-end suffixes. New v3 receipts preserve old formats.
