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.
