+**Advanced classic group lobby preview — 29 October. Prototyped / Partial.**
+The explicitly selected Advanced preview now accepts the group-alliance lobby
+choice for three to six classic factions, without expansion decks or other
+optional modules. A genuine setup and Nexus journey forms a group, exercises
+bot proposals and continues to the next turn. Twenty-four related cases,
+typecheck, lint and the production build pass. Full group rules, expansion
+combinations and deployed acceptance remain open.

 cases, typecheck, lint and the production build pass. Full group interactions,
