Prototype Moritani Assassinate Leaders with saved Mentat replacement

Connect a qualifying native Advanced Moritani battle loss to private reveal/continue controls, live or already-dead opposing-faction targets, printed-strength bank bounty, and automatic Mentat replacement. Keep the revealed physical card held until Mentat, then set it aside as a public per-faction use marker and draw one private card. All four AI profiles use the owner-only legal quote. New local preview profile supports genuine setup without opening public starts.

Keep unresolved normal traitor-call duration and uniform private no-choice UX explicit. Record normal calls and guard later use without claiming a settled permanent loss. Exclude exceptional captured/foreign leader custody, other expansion factions and combined optional modules from this bounded preview. No mode or publication gate opens.

Independent source/privacy/persistence review and 32 focused cases pass. Battle obligations independently bind cleanup, sealed normal-call logs wait for public revelation, physical replacement custody rejects missing cards and forged same-turn chains, and invalid actions remain immutable. Five authenticated SQLite cases cover pending/resolved restoration, Truthtrance interruption, competing submissions, stale/duplicate actions and corrupt saves. The local writer preserves seats and unrelated rooms.

Validation: types, lint, 4690 offline tests, production build and 43 HTTP tests passed with unchanged source. Two genuine Advanced four-profile games finish in 296 and 101 actions with zero rejected candidates, ten periodic JSON rounds and eight restored final seat views. All physical cards, forces and elites remain conserved. Two observed assassination opportunities are declined; these complete games do not establish natural reveal/replacement use.

The separate browser exercise explicitly stages conserved battle forces and one physical traitor swap after genuine setup. Actual battle actions open the choice. Master Bewt dies once and pays three spice; the card remains held through cleanup and is automatically replaced at Mentat with a public set-aside marker. Pending and resolved refresh, readable context-correct inspectors, physical custody and private projection pass. Guild independently collects two spice from Arrakeen. The saved QA game remains at human Terror placement.

After the reported outage, all 801 opening games and original seat/recovery records are preserved (835 after HTTP checks). All 802 rooms and original records immediately before verification also remain unchanged. Database integrity and foreign keys pass. The healthy server was reused without restart, reset or recurring automation.
