Reuse original copied-weapon and typed coalition accounting for bare Basic
Ecaz/Moritani and selected Ix. Preserve optional-module guards and physical
card identity, actual force-owner commitments and native continuations.

 | Duke Vidal revival custody | The user selected living set-aside custody after Ecaz revives Duke; a separate Ambassador/Nexus acquisition grants battle control. Only Ecaz may revive him, including Ghola. Native repeated returns now use the separately labelled provisional identity-cohort policy, not a new publisher example or user number. Captured scope and broad combinations remain separately bounded. | [Selected custody](ECAZ_REVIVAL_RULES.md#selected-product-interpretation-28-september-2026), [current cohort policy](ECAZ_REVIVAL_RULES.md#identity-tracked-repeated-cohorts--14-october-2026) |
-| 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) |

The original Tooth/Artillery cards retain their named mandatory-discard exceptions. This is a product interpretation, **not** a located publisher ruling.

 | Advanced Kull specific effect | Supplied physical29/logical27 restricts the attempted Karama for a specific effect, unlike publisher Basic phase-wide wording. New signed Advanced attempts bind semantic purpose; purchase/payment and native special variants normalize, as do enhanced Prescience/advisor conversion. CHOAM effects and special-force faction powers stay distinct. Retaining turn/phase expiry is explicit provisional composition under the 14 October policy, not supplied wording. Legacy unstamped pending/restriction frames retain broad scope. Prior distinct counter, BG-before-conversion and deferred overbid selections stay. | [Source cutover and keys](CHOAM_KULL_SOURCE_UPDATE.md#advanced-specific-effect-scope--18-october-2026), [connected implementation and limits](CHOAM_KULL_DESIGN.md#advanced-effect-scope--18-october-2026) |
 | Kull Wahad preview timing | User selected a **distinct eligible counter** while the interrupted physical card stays reserved, and BG Worthless interception **before conversion/discard**. Pending declaration is not a ban; only success stamps turn/phase and retains original/special once-use. Decline or prevention resumes the original once. Old `kull` stays printed-only; fresh `nexus-kull` admits native CHOAM plus classic Basic/Advanced seats, CHOAM/Ix Treachery and Nexus alone, without physical Sandtrout. Nexus Use needs actual unallied CHOAM Nexus and canonical eligible own fuel: accepted declaration spends Nexus even if prevented, fuel stays held until success. Use requires source/event/card, with no old-source action shim or proactive Kull. Verified prior printed counter saves migrate only their selection binding; no new-choice retrofit. Reservations, promises and remaining winning-payment coverage constrain fuel/counters; ordinary retained Karama payment is not a canceled Cunning effect. Priority/custody/overbid are user policy; neutral timing/spend conventions are application policy. Bounded checks/CLI/runtime/phone cases pass; broader verification is Partial and no full/public/deployed gate opens. | [Selected preview policy](CHOAM_KULL_SOURCE_UPDATE.md#user-selected-preview-timing--30-september-2026), [source/cost boundary](NEXUS_CHOAM_RULES.md#kull-source-cost-and-action-boundary), [runtime and remaining limits](CHOAM_KULL_DESIGN.md), [new evidence](NEXUS_CHOAM_RUNTIME.md#five-part-status-for-the-new-interaction) |
 | 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) |
