+### Original native bank-auction admission — 14 October 2026
+
+The same printed purchase now applies in existing original native Nexus
+roster/module envelopes: single/paired/mixed E1/E2 and standalone/paired/mixed
+E3, including each canonical predicate's own Skills/Discovery/Homeworld/Tech/
+Stronghold composition. This removes a prototype classic-only fence, not a
+new operation, timing ruling or permission to create an unsupported packet.
+No native Emperor may be seated; actual holder must be unallied, hold the full
+positive price personally, and meet original source/hand-capacity rules.
+
+Uniform public winner payment remains independent of concealed face. Original
+normal bank lot, paid/Karama choices, one physical acquisition, Harkonnen bonus
+and next-lot Atreides inspection continue; the bank receives nothing on Use.
+Native Richese's ordinary pool is not its cache/Black Market; no seller income
+or extra source is created. Existing bank receipt/event/signature stays unchanged.
+The old classic predicate is explicitly retained/reused for prior admission
+parity and strict **legacy physical revival** evidence. No legacy force replay
+or native return-history broadening follows the new bank admission.
+
+Affected16-file union217/217, types/lint/build and thirty-six actual native API
+profiles pass. Every six expansion natives has Basic/Advanced Pay/Use and
+Advanced Homeworld/Tech Pay/Use, preserving actual wallets/card/module inventory
+and next-lot inspection. Four actual390px surfaces prove Richese5→5 and
+Ecaz12→12 with original Homeworld/Tech unchanged, Basic Tleilaxu5→5, and
+irrelevant-card CHOAM Pay14→12 with Guild Nexus retained. One original card,
+actual Nexus cost and index0→1 remain; Atreides sees the actual next card.
+No overflow/browser errors; no saved/deployed room touched. Full combinations,
+assurance and publication/deployed gates remain.
+
+Fixture-only assumptions requiring a response when nobody can cancel, or a
+universal five-disc CHOAM roster excluding Auditor, are deleted rather than
+re-pinned. Native automatic inspection/bonus remains original. QA now serves
+the existing public asset root; this is not complete artwork acceptance.
