 Ten regression cases in `tests/karama-intents.test.ts` cover all variants, serialization, preparation purity/no random draw, stale timing/custody/resources, copied CHOAM selection, exact declaration binding, deferred Harkonnen randomness, injected execution failure isolation, dispatcher parity and preserved CHOAM exceptions. The full 728-case unit suite and 33 persisted/database cases pass.
 
-This prerequisite does not add a pending Kull frame, a phase restriction, or any counter-priority interpretation. The user has been asked whether to use a documented provisional policy (reserve the attempted card, allow a different Karama to counter Kull before its ban, intercept BG before conversion/discard) while CHOAM stays gated. No answer has been received at this checkpoint, so dependent timing implementation remains pending.
+This prerequisite does not add a pending Kull frame or phase restriction. On 30 September the user approved the distinct-card counter and pre-conversion BG interpretation, while deferring unpayable winning overbids; see the [selected preview policy](CHOAM_KULL_SOURCE_UPDATE.md#user-selected-preview-timing--30-september-2026). Dependent Kull timing implementation remains unfinished.
