Subject: [PATCH 01/10] Major architecture refactor: dependency injection,
 controlled mode, split APIs
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

BREAKING CHANGES:
- Storage adapters now memoized and persistent (fixes cache-wiping issues)
- Enhanced loading state propagation to all UI components
- Split API configuration into chatApiConfig/storageApiConfig

NEW FEATURES:
- Dependency injection: inject pre-configured chatService, storageManager, storageAdapter
- Controlled mode: full external control over conversation lifecycle via props
- Status callbacks: onStatusChange, onChatStatusChange, onStorageStatusChange
- Better error handling and loading states throughout the component

FIXES:
- RemoteStorageAdapter existingConversationIds cache no longer wiped on re-creation
- ConversationList now receives proper loading state
- All handlers support both controlled and uncontrolled modes
- Memoized services prevent unnecessary re-creation

Addresses fundamental issues with remote API integration and makes the
library production-ready for real-world applications.

+### With Dependency Injection (v0.4.0+)
+
+Inject pre-configured services for custom auth, retries, or caching:
+
+```tsx
+import { ChatInterface } from '@livefire2015/solid-ag-chat';
+import { createAGUIService } from '@livefire2015/solid-ag-chat';
+import { createRemoteStorageAdapter, StorageManager } from '@livefire2015/solid-ag-chat';

+      'X-App-Version': '1.0.0'
+    },
+    endpoints: {

+      'Authorization': `Bearer ${getAuthToken()}`

+        }
+      }}
+    />
+  );
+}
+```
+
+### With Split API Configuration (v0.4.0+)
+
+Use different hosts for streaming vs CRUD operations:
+
+```tsx
+function MultiHostChatPage() {
+  return (
+    <ChatInterface
+      // Streaming chat goes to one service
+      chatApiConfig={{
+        baseUrl: 'https://chat-stream.myapp.com',
+        headers: { 'Authorization': `Bearer ${getChatToken()}` },
+        endpoints: {
+          streamMessage: '/v1/stream'

+      }}
+      // CRUD operations go to another service
+      storageApiConfig={{
+        baseUrl: 'https://api.myapp.com',
+        headers: { 'Authorization': `Bearer ${getApiToken()}` },
+        endpoints: {
+          getConversations: '/v2/conversations',
+          createConversationWithMessage: '/v2/conversations/create'
+        }
+      }}
+      storageMode="remote"
+    />
+  );
+}
+```
+
+### With Controlled Mode (v0.4.0+)
+
+Take full control over conversation state management:
+
+```tsx
+function ControlledChatPage() {
+  const [conversations, setConversations] = createSignal([]);
+  const [currentConversationId, setCurrentConversationId] = createSignal(null);
+
+  const handleConversationCreate = async (data) => {
+    const response = await fetch('/api/conversations', {
+      method: 'POST',
+      body: JSON.stringify(data)
+    });
+    const newConversation = await response.json();
+
+    setConversations([newConversation, ...conversations()]);
+    setCurrentConversationId(newConversation.id);
+    navigate(`/chat/${newConversation.id}`);
+
+    return newConversation.id;
+  };
+
+  return (
+    <ChatInterface
+      controlled={true}
+      conversations={conversations()}
+      currentConversationId={currentConversationId()}
+      onConversationCreate={handleConversationCreate}
+      onConversationSelect={(id) => {
+        setCurrentConversationId(id);
+        navigate(`/chat/${id}`);

+## v0.4.0 Migration Guide
+
+### Breaking Changes
+
+**1. Storage Adapter Behavior**
+- Storage adapters are now memoized and persistent across component lifecycle
+- Fixes cache-wiping issues that caused duplicate API calls
+- **Action Required**: None for basic usage, but performance will improve
+
+**2. Enhanced Loading States**
+- Loading states now properly propagate to all UI components
+- **Action Required**: Update any custom loading indicators to use new status callbacks
+
+### New Features You Should Adopt
+
+**1. Split API Configuration (Recommended)**
+```tsx
+// Before (v0.3.x)
+<ChatInterface
+  apiConfig={{
+    baseUrl: 'http://localhost:3001',
+    endpoints: {
+      streamMessage: '/chat/stream',
+      getConversations: '/conversations'
+    }
+  }}
+/>
+
+// After (v0.4.0) - Better separation of concerns
+<ChatInterface
+  chatApiConfig={{
+    baseUrl: 'https://chat-api.myapp.com',
+    endpoints: { streamMessage: '/v1/stream' }
+  }}
+  storageApiConfig={{
+    baseUrl: 'https://api.myapp.com',
+    endpoints: { getConversations: '/v2/conversations' }
+  }}
+/>
+```
+
+**2. Dependency Injection for Production Apps**
+```tsx
+// Before (v0.3.x) - No control over service creation
+<ChatInterface apiConfig={config} />
+
+// After (v0.4.0) - Full control with auth, retries, etc.
+const chatService = createAGUIService({
+  ...config,
+  headers: { 'Authorization': `Bearer ${token}` },
+  timeout: 30000
+});
+
+<ChatInterface chatService={chatService} />
+```
+
+**3. Controlled Mode for Complex Apps**
+```tsx
+// Before (v0.3.x) - Limited external control
+<ChatInterface
+  onNewConversation={() => navigate('/chat')}
+/>
+
+// After (v0.4.0) - Full external control
+<ChatInterface
+  controlled={true}
+  conversations={myConversations}
+  currentConversationId={currentId}
+  onConversationCreate={handleCreate}
+  onConversationSelect={handleSelect}
+/>
+```
+
+**4. Status Callbacks for Better UX**
+```tsx
+// New in v0.4.0 - Monitor loading/error states
+<ChatInterface
+  onStatusChange={(status) => {
+    if (status.loading) showGlobalSpinner();
+    if (status.error) showErrorToast(status.error);
+  }}
+  onChatStatusChange={(status) => {
+    // Handle chat-specific status
+  }}
+  onStorageStatusChange={(status) => {
+    // Handle storage-specific status
+  }}
+/>
+```
+
+### Backward Compatibility
+
+All v0.3.x code continues to work in v0.4.0 with these deprecation warnings:
+- `apiUrl` prop → Use `chatApiConfig` instead
+- `apiConfig` prop → Use `chatApiConfig` and `storageApiConfig` instead
+
+### Performance Improvements
+
+**Before v0.4.0 Issues:**
+- Remote storage adapters recreated on every call (cache loss)
+- Loading states not properly propagated
+- No way to inject auth-aware services
+
+**After v0.4.0 Benefits:**
+- ✅ Persistent adapters preserve caches
+- ✅ Proper loading state propagation
+- ✅ Full service dependency injection
+- ✅ Split concerns for streaming vs CRUD
+- ✅ Production-ready architecture

Subject: [PATCH 03/10] feat!: Dramatic API simplification - eliminate prop
 soup
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

BREAKING CHANGES:
- Simplified ChatInterface from 30+ props to just 4 props
- All configuration consolidated into single 'config' object
- All event handlers consolidated into single 'onEvents' object
- Smart mode detection based on configuration
- Clear separation between storage location and state control

New clean API:
- apiUrl?: string (backward compatibility only)
- mode?: 'local' | 'remote' | 'controlled'
- config?: Partial<ChatConfig>
- onEvents?: Partial<ChatEventHandlers>

-### Breaking Changes
-
-**1. Storage Adapter Behavior**
-- Storage adapters are now memoized and persistent across component lifecycle
-- Fixes cache-wiping issues that caused duplicate API calls
-- **Action Required**: None for basic usage, but performance will improve
+## Migration Guides
 
-**2. Enhanced Loading States**
-- Loading states now properly propagate to all UI components
-- **Action Required**: Update any custom loading indicators to use new status callbacks
+### v0.4.1 Migration Guide - Dramatic API Simplification
 
-### New Features You Should Adopt
+**BREAKING CHANGES**: v0.4.1 dramatically simplifies the API from 30+ props to just 4 props.
 
-**1. Split API Configuration (Recommended)**
+**Before (v0.4.0 and earlier) - "Prop Soup":**
 ```tsx
-// Before (v0.3.x)
-<ChatInterface
-  apiConfig={{
-    baseUrl: 'http://localhost:3001',
-    endpoints: {
-      streamMessage: '/chat/stream',
-      getConversations: '/conversations'
-    }
-  }}
-/>
-
-// After (v0.4.0) - Better separation of concerns
 <ChatInterface
+  storageMode="remote"
+  conversationId={params.conversationId}
+  autoGenerateTitle={true}
+  createConversationOnFirstMessage={true}
+  userName="Developer"
+  suggestions={suggestions}
+  showEmptyState={true}
+  disclaimerText="AI can make mistakes"
+  onNewConversation={() => navigate('/chat')}
+  onStatusChange={(status) => showToast(status.error)}
   chatApiConfig={{
-    baseUrl: 'https://chat-api.myapp.com',
-    endpoints: { streamMessage: '/v1/stream' }
+    baseUrl: 'https://api.myapp.com',
+    headers: { 'Authorization': `Bearer ${token}` }
   }}
   storageApiConfig={{
-    baseUrl: 'https://api.myapp.com',
-    endpoints: { getConversations: '/v2/conversations' }
+    baseUrl: 'https://storage.myapp.com'
   }}
 />
 ```
 
-**2. Dependency Injection for Production Apps**
-```tsx
-// Before (v0.3.x) - No control over service creation
-<ChatInterface apiConfig={config} />
-
-// After (v0.4.0) - Full control with auth, retries, etc.
-const chatService = createAGUIService({
-  ...config,
-  headers: { 'Authorization': `Bearer ${token}` },
-  timeout: 30000
-});
-
-<ChatInterface chatService={chatService} />
-```
-
-**3. Controlled Mode for Complex Apps**
-```tsx
-// Before (v0.3.x) - Limited external control
-<ChatInterface
-  onNewConversation={() => navigate('/chat')}
-/>
-
-// After (v0.4.0) - Full external control
-<ChatInterface
-  controlled={true}
-  conversations={myConversations}
-  currentConversationId={currentId}
-  onConversationCreate={handleCreate}
-  onConversationSelect={handleSelect}
-/>
-```
-
-**4. Status Callbacks for Better UX**
+**After (v0.4.1) - Clean & Simple:**
 ```tsx
-// New in v0.4.0 - Monitor loading/error states
 <ChatInterface
-  onStatusChange={(status) => {
-    if (status.loading) showGlobalSpinner();
-    if (status.error) showErrorToast(status.error);
-  }}
-  onChatStatusChange={(status) => {
-    // Handle chat-specific status
+  mode="remote"
+  config={{
+    conversationId: params.conversationId,
+    autoTitle: true,
+    createOnFirstMessage: true,
+    userName: 'Developer',
+    suggestions,
+    disclaimerText: 'AI can make mistakes',
+    apiConfig: {
+      baseUrl: 'https://api.myapp.com',
+      headers: { 'Authorization': `Bearer ${token}` }
+    },
+    storageConfig: {
+      baseUrl: 'https://storage.myapp.com'
+    }
   }}
-  onStorageStatusChange={(status) => {
-    // Handle storage-specific status
+  onEvents={{
+    onNewConversation: () => navigate('/chat'),
+    onStatusChange: (status) => showToast(status.error)
   }}
 />
 ```
 
-### Backward Compatibility
+**Key Changes:**
+1. **30+ props → 4 props**: `mode`, `config`, `onEvents`, `apiUrl` (legacy)
+2. **Smart Mode Detection**: Auto-detects mode based on configuration
+3. **Consolidated Config**: All settings in single `config` object
+4. **Event Consolidation**: All callbacks in single `onEvents` object
+5. **Backward Compatibility**: `apiUrl` prop still works
 
-All v0.3.x code continues to work in v0.4.0 with these deprecation warnings:
-- `apiUrl` prop → Use `chatApiConfig` instead
-- `apiConfig` prop → Use `chatApiConfig` and `storageApiConfig` instead
+### v0.4.0 Migration Guide - Architecture Refactor
 
-### Performance Improvements
+**Storage Adapter Improvements:**
+- Storage adapters are now memoized and persistent across component lifecycle
+- Fixes cache-wiping issues that caused duplicate API calls
+
+**Enhanced Loading States:**
+- Loading states now properly propagate to all UI components
 
-**Before v0.4.0 Issues:**
-- Remote storage adapters recreated on every call (cache loss)
-- Loading states not properly propagated
-- No way to inject auth-aware services
+**New Features:**
+- Dependency injection for `chatService` and `storageAdapter`
+- Split API configuration for different concerns
+- Controlled mode for external state management
+- Enhanced status callbacks
 
-**After v0.4.0 Benefits:**
-- ✅ Persistent adapters preserve caches
-- ✅ Proper loading state propagation
-- ✅ Full service dependency injection
-- ✅ Split concerns for streaming vs CRUD
-- ✅ Production-ready architecture
+**Backward Compatibility:**
+All v0.3.x code continues to work with deprecation warnings.

Subject: [PATCH 05/10] Create AG-UI core compatibility layer
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

- Add comprehensive compatibility layer for @ag-ui/core integration
- Implement official EventType enum with complete 20-event specification
- Create enhanced message interfaces extending official AG-UI types
- Add converter functions for seamless migration between type systems
- Provide backward compatibility while enabling future standardization

Key features:
- Official AG-UI Message, ToolCall, and Event interfaces
- Enhanced types for solid-ag-chat specific features
- Runtime validation placeholder for EventSchemas
- Type-safe event handling with discriminated unions

Subject: [PATCH 06/10] Refactor type system to use AG-UI core compatibility
 layer
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

- Import all AG-UI types from compatibility layer for standardization
- Use 'export type' syntax for proper TypeScript isolated modules support
- Separate value exports (EventType, constants) from type exports
- Remove duplicate type definitions to avoid conflicts
- Maintain full backward compatibility through re-exports

This change centralizes type management and prepares for seamless
transition to official @ag-ui/core when API stabilizes.

Subject: [PATCH 07/10] Migrate service layer to use official AG-UI core
 patterns
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

- Use official convertToOfficialRunInput for API request formatting
- Implement runtime event validation with EventSchemas support
- Fix import strategy for value vs type imports (EventSchemas as value)
- Add graceful fallback when EventSchemas is not available
- Enhance type safety with official AG-UI request/response patterns

Key improvements:
- Standard AG-UI request format with threadId/runId pattern
- Runtime validation that activates when @ag-ui/core is fully available
- Backward compatible event handling with improved type safety

 ## Migration Guides
 
+### v0.5.0 Migration Guide - @ag-ui/core Integration
+
+**NEW**: v0.5.0 integrates with the official `@ag-ui/core` TypeScript types and events for improved standardization and future compatibility.
+
+**What Changed:**
+- Added `@ag-ui/core` dependency for official AG-UI protocol types
+- Created compatibility layer for gradual migration
+- Enhanced runtime validation with official EventSchemas (when available)
+- Improved type safety and IntelliSense support
+
+**Benefits:**
+- **Standardization**: Uses official AG-UI protocol types
+- **Future-Proofing**: Seamless transition when `@ag-ui/core` API stabilizes
+- **Type Safety**: Enhanced TypeScript support with official interfaces
+- **Validation**: Runtime event validation with official schemas
+- **Backward Compatibility**: All existing code continues to work
+
+**No Breaking Changes:**
+All v0.4.x code continues to work unchanged. The migration is fully backward compatible.
+
+**Enhanced Features:**
+```tsx
+// Official AG-UI types are now used internally
+import type {
+  EventType,           // Official AG-UI event enum
+  AGUIMessage,         // Official message interface
+  AGUIEvent,          // Official event union type
+  EnhancedAGUIMessage, // Extended with solid-ag-chat features
+} from '@livefire2015/solid-ag-chat';
+
+// Runtime validation automatically uses official schemas when available
+const chatService = createAGUIService({
+  baseUrl: 'http://localhost:8000',
+  // EventSchemas validation is applied automatically
+});
+```
+
+**Migration Benefits:**
+- **Immediate**: Better TypeScript IntelliSense and type checking
+- **Future**: Automatic compatibility with official AG-UI ecosystem
+- **Performance**: Optimized event handling with official types
+- **Validation**: Runtime safety with official event schemas

+### Event Handlers
+```tsx
+interface ChatEventHandlers {
+  // Status monitoring
+  onStatusChange?: (status: ServiceStatus) => void;
+
+  // Navigation
+  onNewConversation?: () => void;
+
+  // Conversation lifecycle (for controlled mode)
+  onConversationCreate?: (data: Partial<Conversation>) => Promise<string>;
+  onConversationSelect?: (id: string) => void;
+  onConversationUpdate?: (id: string, updates: Partial<Conversation>) => Promise<void>;
+  onConversationDelete?: (id: string) => Promise<void>;
+}
+```
+
+### Supporting Types
+```tsx
+interface SuggestionItem {
+  id: string;
+  icon?: string;
+  category: string;
+  title: string;
+  description: string;
+}
+
+interface ServiceStatus {
+  loading: boolean;
+  error?: string;
+  lastUpdated?: string;
+  details?: Record<string, unknown>;
+}
+```
+
+### Usage Modes
+
+- **`local`**: Data stored in browser localStorage, no backend required
+- **`remote`**: Full backend integration with conversation persistence
+- **`controlled`**: External state management, you control all data operations

Subject: [PATCH 10/10] Fix endpoint URL building for streamMessage with
 conversationId
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

- Fix bug where custom streamMessage endpoints with {conversationId} placeholder
  were not being used correctly when conversationId was provided
- Properly handle endpoints that require conversationId parameter replacement
- Use 'default' as fallback conversationId when endpoint needs it but none provided
- Ensure configured endpoints like '/api/chat/c/{conversationId}/stream' work correctly

Previously: Custom endpoints would fall back to '/agent/stream'
Now: Properly uses configured endpoint with conversationId replacement

Fixes issue where POST requests were going to wrong endpoint despite
correct streamMessage configuration.
