+**CHOAM Nexus Cunning update, 10 September 2026:** the existing physical Nexus can fund one of five supported Worthless effects with an actual held Treachery Card of any category. Shared controls show the cost card separately from the selected effect and retain its full inspector; the engine preserves its canonical identity through allowance, cancellation and legitimate payment loss. No duplicate Worthless piece or artwork is created. The printed family has six effects: Kull Wahad remains unavailable. [NEXUS_CHOAM_RUNTIME.md](NEXUS_CHOAM_RUNTIME.md) records thirty new regressions, browser inspection and private recovery; complete CHOAM and module acceptance remain gated.

 **Emperor Nexus Cunning update, 10 September 2026:** five existing ordinary counters can temporarily count as Sardaukar for one Advanced battle after the native Karama response allows the declared enhancement. No starred piece is created or transferred; casualties remain ordinary counters. Shared strength/support limits drive the editor and bots, and public notices distinguish pending versus active roles. This uses existing Nexus and force components without new artwork. Five-counter eligibility, existing commitments and all other Emperor mode gates remain explicit. [NEXUS_SARDAUKAR_RUNTIME.md](NEXUS_SARDAUKAR_RUNTIME.md) records 35 new cases, browser inspection, private recovery and the full-project checks; complete module acceptance remains pending.
 
 **Bene Gesserit Nexus Cunning update, 10 September 2026:** existing physical advisors now have an owned whole-territory conversion checklist with counts, select-all control and explicit blocked reasons. One played Nexus card opens one Karama response for the entire public selection; no additional card, token or artwork is created. Legal selected groups become fighters in place without consuming shipment, movement or spice. Fresh accompanied advisors and storm cases remain explicitly pending rulings. Borrowed Voice, Betrayal and incomplete mode starts remain gated. [NEXUS_ADVISOR_RUNTIME.md](NEXUS_ADVISOR_RUNTIME.md) records the bounded runtime and verification status; final acceptance is pending.
