Support owned Box and Kulon movement-promise preparation

Extend bounded Basic ground-movement reachability to held native CHOAM Kulon and owned paid Box recovery. Before payment, use only known current-discard identities. Preserve actual paid event, full inspection, one two-spice fee, original physical card replay and existing provisional full-hand exchange. Reject a Yes-breaking selection before the server shuffle without losing the paid search. Keep No-only searches on their normal decision before movement can end.

Record movement-relevant current-discard certainty at actual disposal, paid search, mixed claim and deck rebuild boundaries without projecting raw metadata or erasing historical memory. Use deterministic preparation on private copies, include preparation state in search memoization, protect fee-funded routes from voluntary spending and keep native Kulon counter semantics. Persistent busy-safe guidance and existing legal profiles use the actual next paid action; no strategy tuning.

Verify 17 files231/231, types/lint/build, three original-action control/table-rendering programmes and four existing profiles with40 accepted actions including neutral passes. Original public sources44/25 retain actual purchases1+1, shipment costs6/1, exhausted Hajr and native Kulon route4. Separate full-hand, legacy certainty, fee-loss and acquired-counter edges disclose conserved staging. Two prior-engine Auditor fixture failures are repaired by actual battle-result acknowledgements; test-only const lint is corrected.

Other timing, preparations/counter mitigation, unknown private possibilities, optional/Advanced, full modes, comprehensive assurance and deployed acceptance remain open. No saved-room/reset/restart/deployment operation.

 | 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.

 | 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) |
-| Truthtrance / Basic ground movement | Compose the general FAQ binding-while-possible rule with one future qualifying physical ground movement before the active post-shipment turn ends. Yes survives nonmatches while an owned completion remains; No forbids every later match through Hajr/Ornithopter until actual closure. Commit before arrival/disposal, preserve native controls, and retain compatible promises in accepted order after an opposing loss. Shipment/HMS/Ambassador relocation and the No-Field marker itself do not count as ordinary physical ground movement. This bounded predicate and release priority are software compositions, not a movement-specific publisher FAQ.

 | Semuta / native Basic entries | Fresh bare public Basic Richese previews initialize the existing protocol before genuine setup with selected native E1/E2/E3 families; no optional/Advanced inheritance or old-game retrofit. Clean source-witnessed shipment/movement CHOAM and Ixian Ambassador private discards, including BG copies, park the original entry: keep CHOAM's committed credit and draw the Ixian replacement only after the reaction. This composes printed component rules, not a new timing FAQ.
