 # Dune implementation status
 
+## 18 October 2026 — Native classic independent-card Nexus reactions
+
+Real Harkonnen call with an actually drawn Harkonnen Nexus resolved without
+acknowledgement; actual paid Reinforcements purchase with Ixian Nexus exposed
+no replacement. Fresh classic2–6 Basic/Advanced independent36/Nexus12 optional14
+now initializes both original effect states, Harkonnen only if actually seated.
+Public configuration accepts those intrinsic stamps without admitting other
+overlays. Existing played games without stamps retain their behavior.
+
+Harkonnen physical source recognizes the explicit independent selection and
+retains original three-element historical inventories; selected36 adds one
+true marker. Ixian canonical recognition admits the three original cards only
+in the selected current context, retaining v1 receipt shape. The same neutral
+acknowledgement/native-counter and replacement-before-bonus conventions remain
+visibly provisional. No numeric rule or universal policy is added.
+
+Six new consumer cases exercise personal Use/actual Mentat draw, all14 Pass/
+Traitor-canceled Harass, allied printed counter and allowance, paid replacement
+and original Harkonnen Keep/bonus. The original producer selects unused setup
+and post-training lottery inputs and submits actual skilled-disc shield choices;
+no played card/force/death/clock is assigned. Initial stochastic traitor offers
+and an unhidden trained disc were fixture defects, corrected with native inputs.
+
+Frozen16-file **156/156**, focused6/6, final types/lint and build pass. An
+inferred literal-key Map needed an explicit string key; the type-only correction
+passes final checks without changing runtime. Three actual390px journeys reach
+private real Mentat Traitor inspection, paid2 replacement/next lot, or Basic
+Harkonnen purse8/hand3→4 with purchase/Nexus retained and one bonus. No errors/
+overflow. Four legal policies execute eight native choices and four real Mentat
+draws; Ixian Pass is a legal retention decision, not a calibration result.
+Temporary routes/memory removed/released204, no stored room/reset/restart/deploy.

 Original source audit, 10 September 2026, with dated bounded runtime follow-ups below.

+Initial type feedback required an explicit string-keyed canonical map; its
+type-only correction changes no runtime behavior. Build retains existing
+module-register/large-chunk/route-classification warnings and no QA routes.
+
+The independent36/Nexus12 entry below, optionally all14 Skills, now initializes
+the existing Ixian purchased-card and actually seated Harkonnen declared-Traitor
+effect stamps at fresh setup. Played games without those stamps keep their
+existing behavior. Both protocols are reused, not a second reaction mechanism;
+their original neutral acknowledgement and Harkonnen replacement-before-bonus
+timing remain explicitly provisional. Other reaction overlays stay separate.
+
+Real closing draws supply Harkonnen/Ixian faces. Genuine paid shipment and
+original skilled-disc posture precede Harass plans and the actual native call.
+Personal Use, all-pass, allied Karama preemption/allowance and one actual Mentat
+replacement are connected. Original paid2 independent-card Use/Keep preserves
+wallet/physical delivery and native Harkonnen's one bonus. Public selection
+binds canonical independent identities; no hidden-hand inference or new rules.
+
+New `tests/classic-independent-nexus-reactions.test.ts` has six consumer cases.
+Its named producer uses original unused setup/post-training lotteries,
+alliance/draw, shipment, paid auction and battle actions, not staged played

 Source audit, 10 September 2026. This is a rules contract, not a runtime completion claim. The [common Nexus lifecycle](NEXUS_CARD_RULES.md) and existing expansion release gates still apply. The pending reaction-privacy question remains unresolved; this audit does not authorize a Betrayal reaction policy.
 
+## Classic independent-card native reactions — 18 October 2026
+
+**Prototyped / Partial.** Fresh normal classic2–6 Basic/Advanced
+independent36/Nexus12, optionally all14 Skills, now initializes the existing
+Harkonnen effect state when Harkonnen is actually seated. Ixian replacement
+initializes alongside it. These are native fresh capability stamps, not
+another selected module or a played-save retrofit. Native selected families,
+Worlds, phase modules, Discovery/Semuta and other reaction envelopes remain
+separate. Original standalone base33 admission is unchanged.
+
+The original printed effect below and independent-variant authority compose
+through the same declared-Traitor protocol. Under standing choose-recommended
+authority, inherit the existing visibly provisional native-counter-first /
+public-possible-holder acknowledgement convention for this bounded entry.
+This is not a new publisher ruling or an answer to the universal policy
+outside it. Personal calls gain no new native counter; allied calls retain
+their actual printed Karama allowance first.
+
+The current physical census uses the public independent-card selection, never
+a held face or inferred deck length. Its historical inventory adds a true
+selection marker only for independent36; original three-element inventories
+and signatures retain their grammar. Card identities/names/effects and the
+actual classic Traitor universe remain exact. Starting training and the real
+closing Nexus draw precede the battle; no force, hand, death or clock is staged.
+
+Actual personal Use preserves Harass's one undialed return and the living
+target, returns only the declared Traitor, then draws the real private reserve
+top once at Mentat. All14 Pass retains the actual call: leader death, one
+physical Tank loss and canceled Harass. A real allied printed counter prevents
+the call before any Nexus cost; allowing it opens the same acknowledgement
+with Guild as actual combatant beneficiary. Native skilled-disc shield choices
+are made through their original controls.
+
+Six combined consumer regressions pass in
+`tests/classic-independent-nexus-reactions.test.ts`, backed by its original
+action producer. The actual390px allied scene passes native allowance→owned
+Nexus Use→Harass→original winner inspection→Collection→private Mentat draw,
+including the new actual Traitor inspector. Four legal policies reach Mentat
+with one replacement each. Broader source, assurance and deployed gates remain.

+## Classic independent-card native reactions — 18 October 2026
+
+Fresh normal classic2–6 Basic/Advanced independent36/Nexus12 now initializes
+the original purchased-card effect, optionally all14 Skills, alongside native
+Harkonnen cancellation where that faction is seated. No played game receives
+a new capability stamp. Original standalone classic/Tleilaxu/Richese entries
+and other roster/module boundaries remain; no separate overlay is selected.
+
+The canonical catalogue recognizes the three original independent faces, but
+current sources admit them only from the explicit public selection. Other
+families/cache still require their original selected native context. Historical
+v1 receipts keep their existing shape. This extends physical recognition and
+fresh admission, not printed effect, pricing or universal response timing.
+
+Actual paid2 delivers Reinforcements before the original private buyer choice.
+Use spends one Ixian Nexus, discards only that just-purchased card and draws
+the actual unused deck top, with the same hand size/wallet and one lot advance.
+Pass keeps purchase/Nexus and lets native Harkonnen receive one bonus card:
+actual Basic purse8, hand3→4 and next lot1. Original replacement-before-bonus
+order and neutral wrong-face acknowledgement remain visibly provisional.
+
+Six combined consumer regressions pass. Two actual390px purchase journeys
+exercise all14 Use and native Harkonnen Keep, including original action notices
+and physical hand inspectors; no errors/overflow. Four legal policies retain
+this valuable independent lot with Pass and the original paid wallet.
