+**Two people, four factions — 27 October. Prototyped / Partial.** Each person
+can add a separately authenticated second faction and switch its private view
+and actions. Exactly two controllers with two seats each are required to start;
+ordinary victory uses the four-stronghold target. Independent factions and no
+automatic alliance are provisional. Focused setup, victory, UI and isolated
+HTTP cases pass; complete games, player-count interactions, comprehensive
+custody review and deployed acceptance remain open. Human seats are required;
+handover into a browser holding another active room seat remains unsupported.
+[A dedicated isolated browser room](TWO_PLAYER_TWO_FACTIONS.md) also exercised
+adding, switching and independently readying the host's two factions.
