+## Native Basic Tleilaxu integration — 2 October 2026
+
+The additional fresh admission is **Basic Tleilaxu plus unique classic
+opponents, exactly the original Ix47 Treachery Deck, and Nexus alone**.
+Ixians are absent. This adds to the classic base33 Basic/Advanced profile
+above; it does not admit Advanced Tleilaxu, native CHOAM/Richese, mixed
+expansions or other overlays. Its fresh setup omits the optional physical
+Sandtrout Spice Card, following the existing bounded Ixian Betrayal setup
+convention; existing games and their cards are not changed.
+
+`game/nexus-ixian-replacement.ts` uses the original
+`treacheryDeck(['ix'])` catalogue for exact descriptors. Original base33
+identities remain valid alongside the fourteen original Ix cards; a matching
+ID or generic `special` kind cannot authorize a different name, kind, effect
+or extra field, and unrelated Richese faces do not enter this catalogue.
+The existing source, event, cursor and history APIs remain the only receipt
+path. In particular, buying an Ix special does not replay its payment or
+turn the replacement draw into another purchase.
+
+`tests/fixture-native-ixian-replacement.ts` exports
+`createNativeIxianReplacementFixture` and
+`assertNativeIxianReplacementInventory`. The fixture accepts a fresh native
+lobby or its undealt admitted setup, completes native setup and turn one,
+forms an actual nonrecipient alliance during the next qualifying Nexus,
+and draws the Ixian Nexus through the native lifecycle. It then buys an
+original physical card in a normal auction for two spice. Its default
+purchase is Thumper and its ordered remaining-deck top is Amal; options
+also allow an actual Tleilaxu buyer and the final native auction lot.
+Only conserved undealt cards are reordered; no held Nexus, acquired
+Treachery face, paid-source receipt or continuation is manufactured.
+
+`tests/native-ixian-replacement.test.ts` covers the native special-card
+Use and Pass outcomes, exact discard/top draw, preserved original payment
+and income, native next-lot/final-lot continuation, single Nexus/Treachery
+custody, replay rejection, and forged/unrelated descriptor rejection.
+Existing base-profile full-hand and genuinely depleted-deck regressions
+already exercise the same discard-first/replenishment path and are retained
+rather than duplicated with an artificially emptied native deck.
+
+This is ordinary composition of the printed replacement and existing native
+setup/auction lifecycle, not a new Nexus ruling or a completed family claim.
+Harkonnen buyers, special sale origins, private opportunity timing,
+Richese cache scope and Harkonnen bonus ordering keep their bounds above.
+No pending timing/cancellation, cache, bonus or combined-module question is
+settled by this added deck/faction admission. Verification of this integration
+is reported with the frozen native payment wave, separately from the earlier
+base-profile evidence below.
+
+Bounded native verification passes four meaningful regressions in the shared
+110-case affected batch; final native/guide26/26, types/lint and build pass.
+Twelve actual native programs cover four original Ix purchase/draw pairs,
+Atreides/Tleilaxu buyers, next/final lots and all four legal policies.
+Genuine CLI **XLFRHKPF v6** reaches original native setup. Human390px
+**NMFTVV6N v8** inspects Thumper, spends the original Ixian Nexus, draws Amal,

+## Basic native Banker integration — 2 October 2026
+
+This additive local integration connects the four already-supported Basic native
+Leader Skill families: Ixians (alone or with Tleilaxu), Tleilaxu alone, CHOAM alone,
+and Moritani alone, otherwise classic opponents. Each uses its single required
+Ix, CHOAM, or Ecaz Treachery deck and all fourteen original Leader Skills.
+Advanced native factions, other overlays, mixed expansion families, public
+starts and old-game retrofit remain outside this boundary. The classic
+Basic/Advanced base33 contract above is retained.
+
+`tests/fixture-native-banker-income.ts` creates ready fresh native lobbies and
+calls `initializeSpiceBankerIncomeGameForAudit`, never setting the income flag on
+a played game. Only the original skill shuffle is controlled to obtain a real
+Banker offer; native Treachery, Traitor/Face Dancer and Terror shuffles retain
+their original entropy. Original Ix starting-card selection, skill assignment,
+Traitor/Face Dancer setup, Moritani placement and CHOAM setup continue through
+the engine. Revival examples label their staging: conserved normal/cyborg
+forces move from reserves to Tanks after genuine setup; cancellation cases
+move an original Karama from the remaining deck only if the owner lacks one.
+No sale, payment receipt, pending continuation or deferred grant is fabricated.
+
+The reusable `createNativeBankerIncomeFixture({ family: 'ixians',
+withTleilaxu: true })` case stops before the original final auction payment:
+another payer, the Emperor, buys its native lot for four paid to the Bank.
+`payNativeBankerIncomeFixture` executes that action and its original response
+suffix; `advanceNativeBankerIncomeToPhase(game, 7)` and the existing
+`advanceSpiceBankerIncomeToMentat` continue the real Collection-to-Mentat path.
+The focused regressions cover each native family, actual card delivery and
+debit, unchanged pre-Mentat Banker wallet, deferred collection, Emperor player
+income, and free/paid Tleilaxu-recipient revival. A Tleilaxu own-revival case
+distinguishes its actual four-spice bank debit from the separate printed
+free-revival bank reward; the reward is not another player's payment.
+Canceled Tleilaxu income cases distinguish the actual payer's zero/three/four
+bank debit from the separate free-revival reward included in the native income
+response. In particular, an original three-spice cyborg debit plus one free
+reward must not be mistaken for another player's four-spice bank payment.
+
+Authority remains the photographed Banker card, the existing Leader Skill
+rules and original native payment/recipient rules. This composition does not
+resolve the previously open earned-spice death/capture question. Original
+gaining-faction custody and separate-payer threshold interpretation remain the
+explicitly provisional local policies above; no broader ruling is inferred.
+
+**Bounded runtime evidence:** twelve actual native Banker scenarios pass,
+including all five native compositions through real Mentat, native
+player-recipient exclusions, self-bank revival and canceled income at actual
+cost0/3/4. Three initially failing collection cases stopped at phase8 while the
+existing Ix Amal opening was still pending; the helper now finishes that
+native opening before observing automatic collection. Engine phase ordering
+is unchanged. Final parent checks and human controls are recorded with the
+native payment checkpoint; this is not whole-faction/module certification.
+
+The affected payment rule batch110/110, final native/guide26/26, types/lint
+and build pass. Four additional native post-income policy continuations are
+legal. Genuine CLI **7B55PLA5 v8** reaches original native setup.
+Human390px **86WQMSZV v18** closes the actual Emperor self-auction4, observes
+Ix available10 and deferred1, then finishes original Collection and the
+existing Amal opening before automatic Mentat collection to11. This does not
+approve the pending universal earned-custody policy or enable public starts.

Every answer uses the same private response step; ordinary activation awaits the user’s timing-design decision. Empty hands skip without an answer. Private history is an observation, not a later hand guarantee.',

Declining keeps the use available for a later payment. Paid bribes qualify when transferred, with the remaining share still unavailable until Mentat Pause. Ordinary auctions, Guild income, Richese sales and actual paid Tleilaxu revival income in the Basic Tleilaxu skill profile have connected payment paths. A separate free-revival award is not part of the paid price and stays with Tleilaxu. Split funding, gifts, other payment families and combined modules remain unfinished.',
       'Smuggler records the existing battle-territory spice when plans reveal, capped by the selected leader’s unmodified strength. If that leader survives, it collects automatically even when losing or no forces remain. A captive pays its controller. Pending spice cannot fund the plan. Collection precedes Sandmaster’s addition; a drained pile receives none. Modified strength, multiple positive piles and combined modules remain guarded. Older saved battles keep their original behavior.',

Original bank payer costs exclude the separate Tleilaxu free-revival award; already-earned spice stays with its original faction under the existing provisional policy. Nexus enables the existing private Nexus setup. Moritani-assassinate explicitly opts into the bounded Advanced assassination preview. Semuta opts a fresh Richese roster into bounded clean-discard reactions; an included Ix deck supplies physical Thumper without opening public starts. Kull opts a fresh eligible CHOAM roster into the user-selected Karama interception preview. Richese-betrayal opts a fresh paired CHOAM/Richese Nexus roster into cache-purchase veto and sale-bank diversion. Nexus-kull opts a fresh CHOAM-plus-classic roster with CHOAM/Ix decks and Nexus into source-aware printed or any-Treachery-fueled Cunning Kull. Guild-betrayal opts a fresh classic roster with native Guild into full funded shipment-payment replacement; it preserves an explicitly enabled Homeworld module for Junction routes. Ixian-replacement opts a fresh classic Basic/Advanced base-deck roster, or Basic Tleilaxu plus classic opponents with the original Ix47 deck and no optional Sandtrout, into the exact normal-auction purchased-card replacement with Nexus alone. Native Ixians, Harkonnen buyers and special purchase sources remain unsupported. Ixian-betrayal opts a fresh 2–6-seat Basic/Advanced native Ixian plus classic/Tleilaxu roster with Ix 47-card Treachery and Nexus only into prevention of one actual native Bidding draw or Advanced Technology exchange, after native Karama counters. Harkonnen-betrayal opts a fresh 2–6-seat classic Basic/Advanced roster with native Harkonnen, base 33-card Treachery and Nexus alone into cancellation of an actual declared personal or allied Harkonnen Traitor Card after native counters, physical retirement and shuffle, and one private actual Mentat replacement. Modules, overlays, public starts and old-game retrofits remain excluded. Nexus is not dealt initially: a qualifying alliance requires at least three seats; two unallied receivers require four. Backs up all rooms first, preserves sessions and existing games, and rejects stale versions. Normal game-start and publication gates remain closed.',
       '\nEcaz-occupy (--profile ecaz-occupy) opts only a fresh ready 2–6-seat Advanced lobby with native Ecaz and classic/Ixian/Tleilaxu/CHOAM opponents (optional native Moritani). Distinct selected decks include ecaz and each native ix/choam family; ordinary33/47/35 cards retain real original E3/E1/E2 offers/HMS/Auditor/Face Dancers. Explicit --ecaz-treachery independently adds the three physical variant cards, making36/50/38. No Richese mixed planning, modules or overlays.' +
       '\nLeader-skills accepts explicit --mentat-question for the private uniform Mentat preview. Existing classic/CHOAM skill starts and supported Basic Ixian/Tleilaxu/CHOAM/Moritani native rosters retain their original setup and all fourteen skills. Public activation and the empty-hand ruling remain pending; no other modules or Advanced native skill rosters are enabled.',
