+## 17 October 2026 — Normal-lobby module previews and legal continuation
+
+Hosts can select Leader Skills, the independent three-card Ecaz variant,
+Nexus Cards, Discoveries and Homeworlds beside Tech Tokens and Stronghold
+Cards. Normal starts reuse the genuine fresh setup entries and retain their
+roster/module constraints; Advanced still requires explicit preview opt-in.
+Lobby-only Skills/card selections are consumed at start rather than saved as
+dealt components. Unsupported combined selections reject without dropping an
+option. Ecaz admission also checks that the selected setup can resolve its
+mandatory allied Occupy battle before committing setup.
+
+Changed-path gameplay exposed two real defects: a Basic Occupy winner's named
+variable-army casualties were missing from mandatory card-disposal validation,
+and ordinary Basic bots could copy a fractional target dial into an illegal
+whole-counter plan. Both now continue legally. A next-turn Salusa shipment test
+now uses Polar Sink rather than a sector which the genuine next Storm may block.

+rejects incompatible cards+Nexus with both checkboxes retained, clears readiness
+on correction, starts Skills+independent cards and assigns a real offered skill
+before reaching Traitor selection. No browser errors or horizontal overflow.

+Final types/lint, all **9,866 offline tests** and production build pass. Existing
+Node deprecation, client chunk-size and Vinext route-classification warnings
