+native exchange action. Five focused files pass 208 cases, including controlled
+card custody, Yes/No, conflicting card use and hidden-hand permutations. Kull,

+Leader Skill error messages also now describe existing preview support accurately.

 # Truthtrance combined current-turn actions
 
+## Harkonnen special Karama during Bidding — 29 October 2026
+
+**Prototyped / Partial.** In a quiet Advanced Bidding window, a whole-turn
+question can include the Harkonnen respondent's original once-per-game special
+Karama activation. Its source binds the actual owner and current Bidding phase,
+not a particular auction lot. A future successful use of a physical printed
+Karama in that special role after the answer counts; a normal Karama purchase
+or other role, failed or prevented activation, prior use and another player's
+card do not. No forbids only the matching special role while the original window
+remains open. AND/OR answers share the existing native card and payment planner,
+and spending the last necessary card or closing Bidding cannot evade an owned
+Yes. The normal native hand-exchange decision follows actual activation.
+
+The detached legal witness uses the public target hand count and returns the
+unseen drawn cards to their owner; it never samples or reads the target's hidden
+faces or invents their benefits for another promised action. The actual native
+exchange still randomly draws and returns real cards under its existing rules.
+Questions, answers, receipts and guidance retain their existing public/private
+boundaries; human controls and the four minimal bot profiles use the same native
+packet. Current Kull and Semuta profiles are excluded; other faction special
+Karamas, wider timing, mixed-profile combinations, saved-game assurance and
+deployed verification remain open. The question and witness policy compose the
+existing [publisher FAQ](https://www.gf9games.com/dune/wp-content/uploads/2020/11/Dune-FAQ-Nov-2020.pdf)
+current-turn Truthtrance authority with the native power; they are provisional
+online interpretations, not a dedicated publisher ruling.
+
+Five focused files pass 208 cases. The [native runtime fixture](../tests/truth-harkonnen-special-karama-runtime.test.ts)
+reaches Advanced Bidding through actual actions, with a controlled swap of the
+original physical Truthtrance and Karama. It covers Yes/No, hand exchange,
+source identity, private hands, hidden-Hajr permutations, ordinary Karama cost
+protection and minimal bot guidance. The swap is not claimed as an earned card
+acquisition. Focused evidence does not certify complete modes.
