 # Dune implementation status
 
+**Bene Gesserit Nexus advisor checkpoint, 10 September 2026:** [NEXUS_ADVISOR_RUNTIME.md](NEXUS_ADVISOR_RUNTIME.md) records whole-territory, multi-sector Cunning conversion during the native owner’s Advanced Shipment and Movement action. One Karama cancels the entire declared batch; source positions, counts and action allowances are preserved. Saved responses survive Truthtrance, Harkonnen exchanges and paid Nullentropy. Shared controls and all four bot profiles consume the public legality quote. **Types, lint, all 3,971 offline tests, production build and 40 HTTP/session tests pass.** Thirty-five new cases include pending-parent corruption, physical custody and concurrent production SQLite recovery. Two three-seat browser rooms passed desktop/phone selection, allowance/cancellation and private refresh; review also fixed checkbox spacing, accessible SVG titles and stale Nexus guidance. All **3,389** opening saved rooms retain their versions/hashes; only two isolated browser rooms and thirty HTTP-test rooms were added. Fresh advisor/storm rulings, borrowed Voice, Betrayal and complete module acceptance remain gated. The Emperor source audit prepares the next family. No release gate opened; no restart was due, and automation remains removed.

 **Tleilaxu and Ixian Nexus Cunning checkpoint, 10 September 2026:** [NEXUS_CUNNING_RUNTIME.md](NEXUS_CUNNING_RUNTIME.md) records atomic revealed Face Dancer replacement and full-strength Suboids in every battle for the rest of the turn. Basic and Advanced retain Cyborg support costs and exact physical losses. Review fixed fresh Ixian Nexus setup, future-plan search through an unspent Cunning card and its private preparation hint; prior commitments remain binding. **Types, lint, all 3,936 offline tests, production build and 40 HTTP/session tests pass.** Fifty-one new cases include real Face Dance, all four bots, mixed-force support, concurrent SQLite recovery and future Truthtrance/Prescience commitments. Desktop/phone card play, private refresh and a seven-strength/two-support sealed plan passed. The hourly restart preserved all **3,359** then-existing games; final comparison preserves all **3,327** opening room versions/hashes. Tleilaxu Secret Ally, Betrayal and remaining Nexus effects stay gated pending their recorded requirements. No expansion release gate opened; automation remains removed.
 
 **Harkonnen Nexus exchange checkpoint, 10 September 2026:** [NEXUS_HARKONNEN_RUNTIME.md](NEXUS_HARKONNEN_RUNTIME.md) records draw-first Cunning and absent-faction Secret Ally, exact private returns, protected revealed Face Dancers, saved suspended actions and durable prior traitor declarations. Shared controls and all four bot profiles use projected identities. Independent review fixed lost preceding decisions and the paid Nullentropy action gate. **Types, lint, all 3,885 offline cases, production build and 40 HTTP/session cases pass.** Forty-six new cases cover rules, consumers, continuations and concurrent SQLite recovery. Two three-seat browser rooms passed draw/return, private restoration and desktop/phone inspection. All **3,295** preexisting room versions/hashes remain unchanged. Betrayal remains blocked pending the existing private response timing decision; complete Nexus and expansion games remain unfinished, and no release gate opens. The server was reused, no restart was due, and automation remains removed.
