+## 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.
