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.
