 | Duke Vidal revival custody | The user selected set-aside custody after Ecaz revives the shared disc: revival clears the Tanks but does not itself grant battle control. Ecaz still needs a separate Ambassador or Nexus acquisition; only Ecaz may revive Duke, including by Ghola. This resolves one post-revival product interpretation, **not** the separate six-disc repeated-cycle, exceptional capture or battle-used Ghola questions. No publisher clarification assigning a post-revival controller was located. | [Publisher Ecaz/Moritani pp. 7–9](https://gamers-hq.de/media/pdf/0f/7a/86/Dune_EcazMoritani_Rulebook_EN.pdf#page=9), [revival readiness](ECAZ_DUKE_REVIVAL_READINESS.md) |
 | Mirror Weapon copied-card cleanup | The user selected ordinary winner retention for the physical Mirror even if its effective copy activates Tooth or Artillery. The original Tooth/Artillery cards retain their named mandatory-discard exceptions. This is a product interpretation, **not** a located publisher ruling. Independent copy-first Tooth/Stone choices and physical cleanup now have a bounded CHOAM/Richese-deck battle runtime; combined modules and full Richese games remain gated. | [Printed Mirror face and source audit](MIRROR_WEAPON_ENGINE_AUDIT.md#user-selected-cleanup-interpretation-28-september-2026) |
+| Kull Wahad preview timing | User selected a distinct eligible Karama counter while the interrupted card stays reserved, and interception of BG Worthless-as-Karama before conversion/discard. A prevented unplayable winning overbid remains guarded; no remedy was approved. Full CHOAM starts remain gated. | [Selected preview policy](CHOAM_KULL_SOURCE_UPDATE.md#user-selected-preview-timing--30-september-2026) |
+| Semuta full-hand exchange | User selected **Allow exchange**: acquisition followed by Semuta disposal is an atomic net-zero hand exchange at the faction limit. Existing incoming reservations still consume capacity; this does not permit an already overfull hand or settle Box/Richese purchase timing. | [Selected capacity policy](SEMUTA_SOURCE_UPDATE_20260907.md#user-selected-full-hand-exchange--30-september-2026) |

 | Recruits late accounting and rates | A user question has been sent for two free plus one paid Atreides return before Recruits: keep the disputed case gated, or one/two further free returns without refund. No answer is assumed. Late-changing free rates, pending repricing and same-turn recovered-card replay also stay gated. The connected clean-case preview retains the independent seven-force cap after faction-advantage cancellation as an explicit inference, not a direct combined FAQ. | [Source audit](RECRUITS_RULES.md), [runtime scope](RECRUITS_RUNTIME.md) |
 | Sandmaster / native HMS relocation | No official source located establishes that passengers remaining inside the HMS enter outside territories for this skill. Extra collection eligibility is pending a user ruling; native sector collection and ordinary force entry/exit remain available. | [Source comparison and question](SANDMASTER_MOVEMENT.md#21-september-native-hms-relocation-eligibility) |
 | Sapho remaining timing | First versus unspent Advanced Guild priority, partly completed combined turns, cyclic auction duration and later battle timing stay guarded.

 | Leader Skills edge cases | Capture/replacement eligibility, Banker escrow custody, Smuggler modifier/allocation boundaries, Mentat empty-hand fallback, modified Diplomat defenses and simultaneous optional timing remain source gaps. After an online publisher/designer/tournament check found no explicit priority ruling, the bounded standalone Diplomat retreat prototype explicitly chooses printed/copied disc strength and a surviving-loser retreat before ordinary casualties; other combinations remain guarded. This is an implementation interpretation, not an official clarification. | [Material boundaries and selected retreat interpretation](LEADER_SKILLS_RULES.md#bounded-diplomat-retreat-interpretation), [Diplomat defense boundary](DIPLOMAT_DEFENSE.md#evidence-and-remaining-scope) |
 | Smuggler collection strength | A fresh primary-source check found no modifier ruling. The user was asked whether to keep affected combinations gated, use printed/copied disc value, or include leader bonuses with Stunner zero. No answer is assumed. The reveal-bound deferred receipt is supported as an explicit timing inference; unmodified lower collection is now [prototyped](SMUGGLER_BATTLE.md); modified strength, multiple positive piles and combined modules remain gated. | [Smuggler follow-up](LEADER_SKILLS_RULES.md#20-september-smuggler-follow-up) |
 | Suk Graduate / Atreides | Whether rescued dialed casualties count toward the seven-loss Kwisatz Haderach threshold remains unresolved. The user question has been sent; Advanced Atreides rescue stays guarded. | [Source and runtime boundary](SUK_GRADUATE_RULES.md) |
