+# OpenSpec Change: enterprise-gaming-react-dialogue
+
+- **Change ID**: enterprise-gaming-react-dialogue
+- **Package**: `@suaveplan/react-dialogue`
+- **Category**: gaming/react
+- **Target path**: `gaming/react/react-dialogue`
+- **Status**: PROPOSED
+- **Date**: 2026-04-24
+- **Reference spec**: `/mnt/s/web/suaveplan/enterprise/react-dialogue.md`
+

+
+## Summary
+
+Deliver `@suaveplan/react-dialogue` on the genesis branch from scratch at enterprise quality. The package is the headless React layer around `@suaveplan/dialogue`. A `DialogueUIStateManager` wraps a `ConversationSession`; `useDialogue()` provides access via `useSyncExternalStore`; typed components display the current node text, speaker name, typewriter text animation, and choice buttons with condition-gated disabled state. Genesis adds Storybook stories, Vitest DOM tests, and 100% coverage.
+

+
+## Current-state audit (genesis)
+
+Package does not exist on genesis yet — fresh build.

+
+## Available workspace deps on genesis

+| Package | Role |
+|---|---|
+| `@suaveplan/dialogue` (`workspace:^`) | `ConversationSession`, `DialogueTree` |
+| `@suaveplan/events` (`workspace:^`) | Dialogue event subscriptions |
+| `react` (`catalog:react`) | React 18 |
