Enable Residual Poison against Advanced Harkonnen captives

Include available ordinary captives, captured foreign gholas and shared Duke in the original random pool. Apply one public ordinary death without execution income, preserve foreign revival custody and other concealed captives, and end Duke tenure. Find the signed Semuta victim by canonical physical identity after captivity ends. Explain the provisional normal-Tanks source composition in controls and developer reference.

Validation:9 files74/74, types/lint/build and two actual-rule/rendered-table programmes plus four finite policy continuations pass on one frozen source. Details and exact unchanged-source proof are recorded in the canonical Residual Poison contract. Genuine public Advanced cache purchase, funded deployments, native victory/capture/keep and second battle cover native and captive deaths plus finite completion. Four minimal profiles use legal offered card/readiness actions. Separate controlled cases cover ghola/Duke, last-native return and Semuta claim; no strategic AI refinement.

This interpretation remains provisional. Wider interactions, complete modes, final assurance and browser/deployed acceptance remain open. No saved-room/database/reset/restart/deployment operation.

+## 18 October 2026 — Residual Poison with native Harkonnen captives
+
+Remove the Advanced Harkonnen and exceptional-custody card exclusions. All
+available controlled physical discs participate; one ordinary public death
+ends selected captivity with zero bounty. Other living captures stay concealed,
+foreign Ghola revival custody remains, and the shared Duke's tenure ends with
+his original disc/history intact. Last-native Harkonnen death still returns
+survivors. The Semuta suffix locates its signed victim across physical homes
+after control ends; it does not replay death. UI explains provisional normal
+Tanks handling, separate from execution-for-two and known trained-card capture.
+
+A disjoint genuine-fixture lane, bounded source review and owner integration
+pass9-file74/74, types/lint/build and two original-action/rendered-table programmes
+plus four finite policy continuations. Public Advanced start, opening bid1/native
+seller purchase2, paid Hark3/Emperor1 desert and Richese1 Carthag shipments,
+actual win/capture/keep and second battle use70 source actions. Native/captive
+selection from five eligible discs plus final battle uses9 continuations; four
+profiles make eight legal card/readiness proposals and finish. Controlled
+Ghola/Duke/last-native/Semuta probes are separately labelled. Actual GameTable
+and enabled/busy card controls render the consequence.
+
+First feedback corrected only a seller-auction fixture shortcut and the expected
+null resolved-discard sentinel. The whole frozen batch then passes unchanged.
+[Canonical source, exact proof and remaining limits](RICHESE_RESIDUAL_POISON_ENGINE_AUDIT.md#native-captive-death--18-october-2026).
+No browser/visual/deployed, full combination or complete-mode acceptance. Final
+assurance remains due; no saved-room/database/reset/restart/deployment operation.
