Resume native Basic arrivals after Ornithopter recovery

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.

+## Native Ornithopter movement and arrival — 24 October 2026
+
+**Prototyped / Partial.** Fresh bare Basic Richese tables with selected native
+E3 factions now offer Semuta after a completed Ornithopter movement, including
+range-three and the final two-group move. This removes the blanket Ecaz/Moritani
+seat exclusion for that existing public Basic profile. Original classic/
+non-E3 permissions remain; native Advanced E3 and optional combined profiles
+retain their preceding guards. Existing games do not gain a Semuta setup marker.
+
+The physical group and movement counters commit first. The finished card is
+the first fresh group; claim or every-seat Continue retires it before the
+original movement arrival runs. Taking the card does not move the forces again,
+grant another movement or end the original player's turn. The saved completed
+move and existing native-token signature remain unchanged; no new serialized
+field, receipt or arrival rule is introduced.
+
+The original suffix opens a clean single-token Ambassador or Terror entry with
+its actual movement cause. CHOAM private discards retain their already-paid
+three spice per card; Ixian discard pauses before its one replacement draw.
+Sabotage/Robbery overflow keep their native draw/discard and gift continuations.
+Each is a later, separate fresh event. A holder who spends the single physical
+Semuta on Ornithopter cannot spend it again on that later group. Passing the
+first group can preserve it for an eligible later card.
+
+This composes existing printed movement/discard mechanics and the current
+Semuta protocol, not a new publisher timing ruling. Ambassador/Terror overlap
+keeps its existing preflight/order: Ambassador discard admission remains guarded
+while an overlap is active. Other nested arrivals, native Advanced E3,
+optional combinations, complete modes and final acceptance remain unfinished.
+
+### Native Ornithopter source and proof
+
+The Ambassador source reuses only the original public Basic Ecaz/CHOAM/Richese/
+Guild prefix before Guild shipment: paid original cache Orni1, Ecaz's actual
+ordinary purchase1 and token placement1. Its unused constructor normal-move/
+trigger branch is neither replayed nor counted. Prefix56 actions plus1 real
+shipment (range-three) or2 branch actions (shipment2 and first same-territory
+sector move) reach the caller-owned final move. The first two-group counter
+really moves Ridge Flat17→18; the remaining original counter enters Sietch17.
+Only the original cache Semuta is transferred to Richese as labelled acquisition.
+
+The Terror source really starts Basic Moritani/Richese/Guild, chooses native
+Oh Gap setup, buys original Orni1 in turn1, places the actual hidden Terror at
+Mentat, uses legal first zero/later1+1 dials and pays turn2 shipment. Its70/71
+actions reach range-three/final-two-group movement into Carthag11; two-group
+mode first moves another counter to empty Arrakeen10. Robbery's four-card hand
+and optional claimant full hand use labelled conserved ordinary-card
+acquisitions; no force, clock, token or pending receipt is installed.
+
+The first new range-three CHOAM regression fails before admission, then passes.
+Twelve Ambassador cases, eight Terror cases and two actual-state control cases
+cover both modes, flight/later-card recovery, BG copy, empty CHOAM choice,
+original private selection, full hands, single spend, stale first-event
+rejection and exact original continuation. CHOAM credits6 once; Ix draws one
+replacement only after its fresh group; Sabotage gifts one original card or
+declines; Robbery draws one actual top card before its overflow discard.
+Native token/force/card custody stays physical and movement never repeats.
+
+The final affected **10-file135/135** union, npm run check:quick and production
+build pass. Sixteen gameplay/GameTable SSR programmes exercise both modes,
+both recovery points and all four native effect families, through explicit
+movement end. Eight existing-profile later-discard continuations accept28
+proposals, all making a legal claim. Actual Continue/Commit/Select callbacks
+retain their own events; busy handlers submit nothing. No strategy tuning or
+strength calibration occurs. Source feedback corrected setup/phase adapters,
+live flight inventory and later legal Storm dials. The first frozen union
+passed rules but failed a fixture's offer/select type narrowing; the repaired
+final source passes all checks.
+
+Private artifacts: /home/quintine/.local/share/dune/checkpoints/20261024-semuta-native-ornithopter/,
+final frozen-integrated-2/report.json, runtime-smoke.json, private HTML/logs,
