Allow the completed flight discard in the existing bare Basic E3 profile.
Keep physical movement and its original arrival, then handle distinct
Ambassador or Terror fresh groups without replaying effects or Semuta cost.

+## 24 October 2026 — Native Basic Ornithopter recovery and arrival
+
+Admit the completed movement-card fresh group in the existing bare Basic E3
+Semuta profile. Keep the actual moved group/counters and retire that event
+before original movement-caused arrival. Clean CHOAM/Ix Ambassador and
+Sabotage/Robbery overflow then retain distinct fresh groups, original payout,
+one replacement/draw and native gift. The single physical Semuta cannot be
+spent twice. Existing signatures and serialized fields remain unchanged;
+overlap, native Advanced E3 and optional-profile guards remain.
+
+Disjoint source/test lanes, actual control callbacks, bounded continuation
+review and owner integration pass10 files135/135, types/lint/build and sixteen
+gameplay/GameTable SSR programmes across both modes and both recovery points.
+Eight existing-profile later-native continuations accept28 proposals without
+strategy changes. Ambassador prefix56 plus1/2 real branch actions and Terror
+70/71 actions retain actual setup, paid cache Orni, placements and shipments.
+Semuta/overflow/full-hand acquisitions are explicitly conserved staging.
+BG copy and empty CHOAM grants have separate source/control proof.
+
+The pre-change range-three CHOAM case reproduces the missing first offer.
+Source feedback corrects phase handling before traitor setup, the final native
+Moritani setup window, legal next-turn1+1 dials and physical escrow inventory.
+The first frozen rule union passes but type checking finds an offer/select
+narrowing issue in a fixture; its source-qualified pass guard is repaired,
+then final frozen proof passes.
+[Exact source/evidence and remaining gates](SEMUTA_SOURCE_UPDATE_20260907.md#native-ornithopter-movement-and-arrival--24-october-2026).
+No complete-mode/combination or browser/deployed certificate, full AI tuning,
+comprehensive assurance or saved-room/D1/reset/restart/deployment operation.
