Preserve Basic shared arrival reactions through Semuta

Admit the original ordered Ecaz/Moritani entry in bare Basic Richese games, retain both native opportunities during fresh discard recovery, and bind each suspended child to its actual arrival. Show the current discard response in the table banner.

Cover real five-seat setup and placements, both owner orders, physical payouts/draws/gifts, persistent controls and minimal legal bot participation.

 ## Current checkpoint and work
+**Basic shared Ambassador/Terror arrival — 24 October. Prototyped / Partial.**
+The existing bare Basic Richese profile now admits a paid shared native entry.
+Both originally eligible owners keep the selected provisional storm order
+while their separate CHOAM/Ix or Sabotage/Robbery fresh groups offer Semuta.
+Source-qualified child matching preserves the original entry, already-paid
+credit, one draw/gift, full-hand exchange and the other owner's opportunity.
+The table banner explains the shared discard response instead of attributing
+that choice to the paused native owner.
+
+Disjoint real-source/control lanes, bounded continuation review and owner
+integration pass **12 files144/144**, types/lint/build, eight actual gameplay/
+control/GameTable SSR journeys and eight existing-profile continuations
+(69 accepted proposals). Real five-seat setup, lobby circles, paid cache and
+placements supply139–142 source actions. Prior Semuta transfer/overflow hands
+are explicitly conserved staging. Feedback fixes an unopened optional-field
+assertion, two lint declarations and a stale Truthtrance test expecting the
+previously removed native Ornithopter discard exclusion.
+[Source, proof and limits](SEMUTA_SOURCE_UPDATE_20260907.md#basic-shared-ambassador-and-terror-arrival--24-october-2026).
