-# Redux to React Query Migration Guide
-
-This guide outlines the process for migrating from Redux to React Query in our application.
-
-## Overview
-
-The migration strategy allows for a gradual transition from Redux to React Query, with the ability to migrate one slice at a time without breaking the application. This is achieved through a bridge that coordinates between Redux and React Query.
-
-## Key Components
-
-1. **QueryReduxBridge**: A utility class that manages the migration state and coordinates between Redux and React Query.
-2. **Websocket Integration**: Modified to respect migration flags and update the appropriate state management system.
-3. **React Query Hooks**: New hooks that replace Redux slice functionality.
-
-## Migration Steps
-
-### 1. Initialize the Bridge
-
-In your main application file (e.g., `App.tsx`), initialize the bridge:
-
-```tsx
-import { QueryClient, QueryClientProvider } from '@tanstack/react-query';
-import { initQueryReduxBridge } from '#/utils/query-redux-bridge';
-
-const queryClient = new QueryClient({
-  defaultOptions: {
-    queries: {
-      refetchOnWindowFocus: false,
-    },
-  },
-  ...queryClientConfig,
-});
-
-// Initialize the bridge
-initQueryReduxBridge(queryClient);
-
-function App() {
-  return (
-    <QueryClientProvider client={queryClient}>
-      {/* Your app components */}
-    </QueryClientProvider>
-  );
-}
-```
-
-### 2. Replace the WebSocket Provider
-
-Replace the original WebSocket provider with the bridge-aware version:
-
-```tsx
-import { WsClientProviderWithBridge } from '#/context/ws-client-provider-with-bridge';
-
-// Instead of
-// <WsClientProvider conversationId={conversationId}>
-//   {children}
-// </WsClientProvider>
-
-// Use
-<WsClientProviderWithBridge conversationId={conversationId}>
-  {children}
-</WsClientProviderWithBridge>
-```
-
-### 3. Add the WebSocket Events Hook
-
-Add the WebSocket events hook to your application to handle events for React Query:
-
-```tsx
-import { useWebsocketEvents } from '#/hooks/query/use-websocket-events';
-
-function YourComponent() {
-  // This hook will process websocket events for React Query
-  useWebsocketEvents();
-  
-  // Rest of your component
-  return (
-    // ...
-  );
-}
-```
-
-### 4. Migrate Individual Slices
-
-For each Redux slice you want to migrate:
-
-1. Create a React Query hook that replaces the slice functionality
-2. Mark the slice as migrated
-3. Update components to use the new hook instead of Redux
-
-Example for migrating the chat slice:
-
-```tsx
-import { useChatMessages } from '#/hooks/query/use-chat-messages';
-import { getQueryReduxBridge } from '#/utils/query-redux-bridge';
-
-// Mark the slice as migrated
-getQueryReduxBridge().migrateSlice('chat');
-
-function ChatComponent() {
-  // Instead of using useSelector and useDispatch
-  // const messages = useSelector((state) => state.chat.messages);
-  // const dispatch = useDispatch();
-  
-  // Use the React Query hook
-  const { 
-    messages, 
-    addUserMessage, 
-    addAssistantMessage, 
-    addErrorMessage, 
-    clearMessages 
-  } = useChatMessages();
-  
-  // Rest of your component using the new API
-  return (
-    // ...
-  );
-}
-```
-
-## Testing the Migration
-
-To test the migration of a single slice:
-
-1. Create the React Query hook for the slice
-2. Mark the slice as migrated using `getQueryReduxBridge().migrateSlice('sliceName')`
-3. Update a single component to use the new hook
-4. Test the application to ensure it works correctly
-5. If issues arise, you can easily revert by removing the migration flag
-
-## Troubleshooting
-
-### Duplicate Updates
-
-If you see duplicate updates (e.g., chat messages appearing twice), check:
-
-1. Ensure you're using the bridge-aware WebSocket provider
-2. Verify the slice is properly marked as migrated
-3. Check that components aren't mixing Redux and React Query for the same slice
-
-### Console Errors
-
-If you encounter console errors:
-
-1. Check for race conditions between Redux and React Query
-2. Ensure the WebSocket events hook is properly mounted
-3. Verify that the QueryReduxBridge is initialized before any components try to use it
-
-## Complete Migration
-
-Once all slices are migrated:
-
-1. Remove the Redux store and related code
-2. Simplify the bridge code to remove Redux dependencies
-3. Update the WebSocket provider to directly update React Query without the bridge
