Connect Leader Skill battle effects and private Rihani exchanges

Prototype Mentat/Bureaucrat score effects, automatic Sandmaster board spice, and Rihani inspection plus committed exchange. Preserve private views, physical custody, saved winner cleanup and captive/Suk sequencing. Remaining normal bands, missing skill families and combined modules remain gated.

Validation: 45 focused tests; typecheck, lint, 4465 offline tests, production build and 43 HTTP tests passed. Independent rules/privacy/persistence review completed. New isolated browser setup exercised inspection, draw, pending refresh, exchange and completed refresh. Two genuine four-profile Basic/Advanced samples completed without rejected candidates but did not trigger Rihani.

Preserved all 393 opening rooms and original seat/recovery rows (427 rooms after QA/HTTP). SQLite integrity and foreign keys passed. Server remained healthy after the reported outage; no restart or reset.

+13 September 2026. **Prototyped, with Partial rules coverage.** This follow-up
+connects both Rihani Decipherer bands and the lower battle bands of Mentat,
+Bureaucrat and Sandmaster. Normal Mentat questioning, Bureaucrat payments and
+Sandmaster movement collection remain missing, as do Spice Banker, Diplomat and
+Smuggler. Public module starts and publication remain gated.
+
+## Source contract
+
+The [GF9 CHOAM & Richese rulebook, page 9](https://www.gf9games.com/dune/wp-content/uploads/2021/11/CHOAM-Rulebook-low-res.pdf)
+provides the common skill procedure. The printed cards and publisher designer
+walkthrough supply the individual effects; see the [component inventory](LEADER_SKILLS_RULES.md).
+
+- [Mentat, 17:37](https://www.youtube.com/watch?v=XT_azRVLq_0&t=1057s): the
+  surviving selected skilled disc gains two battle strength. Its printed value,
+  bounty and Zoal source value stay unchanged.
+- [Bureaucrat, 15:01](https://www.youtube.com/watch?v=XT_azRVLq_0&t=901s): the
+  surviving selected skilled disc subtracts one from its opponent's total per
+  distinct stronghold that opponent occupies. Contested and storm-covered
+  occupation count; advisors and virtual victory control do not. There is no
+  implicit zero clamp. The shared board helper recognizes HMS and Jacurutu,
+  though combined-module play remains gated.
+- [Sandmaster, 15:48](https://www.youtube.com/watch?v=XT_azRVLq_0&t=948s): a
+  surviving skilled winner adds three board spice to an existing pile in the
+  battle territory automatically. This grants no direct income and does not
+  require surviving forces. No pile means no addition. Multiple positive piles
+  are guarded before the final battle vote pending a sector-placement ruling.
+- [Rihani, 12:49](https://www.youtube.com/watch?v=XT_azRVLq_0&t=769s): a face-up
+  native trainer grants the normal private inspection after a victory using
+  another leader. A surviving selected native skilled winner receives both
+  bands. A surviving captured skilled winner receives only the lower band.
+
+Rihani first privately inspects two random physical Traitor Deck cards and
+reshuffles them. It then offers the separate optional two-card draw. Choosing
+to draw commits the player to keep one newly drawn card, publicly reveal and
+return one unused old card, and secretly return the unkept new card. Those two
+returns are shuffled into the actual deck. There is no post-draw decline or
+return-both-new alternative. The two samples can contain the same identity.
+
+**Ordering inference:** normal-before-lower follows the printed order and
+designer narration; no explicit priority sentence was found. **Unused** means
+not actually called, rather than merely known or publicly disclosed. Returning
+an old card announces its name without adding it to the actual-use register.
+A Traitor Card used to win this battle is already excluded from the exchange.
+No eligible old card means no optional draw. There is no partial draw fallback
+when fewer than two physical deck cards are available.
+
+The [Ixian/Tleilaxu rules](https://www.gf9games.com/dunegame/wp-content/uploads/2020/09/IxianAndTleilaxuRulebook.pdf)
+place skill resolution before faction capture and Face Dance. Tleilaxu Rihani
+must instead exchange an unrevealed Face Dancer. That combination, foreign
+gholas and the skill lifecycle after non-kill Face Dance remain unimplemented.
+The connected entry supports base factions in Basic/Advanced with Leader Skills
+alone. These boundaries are implementation limits, not prohibitions in the game.
+
+## Connected behavior and checks
+
+Shared battle quotes calculate score changes; bots use the same public
+stronghold count. Sandmaster resolves automatically. Rihani offers owned
+draw/decline controls, then separate inspectable keep-new and reveal-old
+selections. All four AI profiles use only their permitted view. Only the owner
+receives inspection history and drawn identities. The public log names the
+returned old card, never the kept or unkept new identity.
+
+Physical snapshots, an event-bound obligation and saved stages preserve Rihani
+through casualties, winner cleanup and captive return. Independent review found
+that completed receipts were not bound to custody during cleanup; this now
+rejects changed deck order after either decline or exchange. JSON and SQLite
+restart tests cover both choices, concurrent writes, stale replays, normal versus
+captured eligibility, actual-use exclusion and native Suk rescue preceding a
+captured Rihani exchange. Focused checks also cover score-boundary winners,
+dead/bluffed skills, Sandmaster without surviving forces and UI privacy.
+
+Fresh browser room `HNGSR8GB` used genuine module setup, then a separately
+staged conserved battle. The human inspected two private cards, drew two
+separate cards, refreshed the pending exchange and selected a keep and public
+return. Completion and refresh restored the kept Traitor and winner card cleanup.
+This is targeted browser evidence, not a naturally reached complete game.
+Two genuine four-profile Basic/Advanced samples completed in 92/188 actions,
+with 3/6 JSON continuations and no rejected candidates; neither reached a Rihani
+effect. They establish sample continuation, not comprehensive skill acceptance.
+
+The running server responded after the reported outage. A fresh online backup
+captured all 393 opening rooms. No restart or reset was needed. Required broad
+checks and final saved-game preservation are recorded in the checkpoint commit
+and private source-bound report.
