+# Changelog
+
+## 2025-09-12 - 2.0.27 - fix(StatePart)
+Use stable JSON stringify for state hashing; update dependencies and tooling
+
+- Replace smartjson.stringify with smartjson.stableOneWayStringify when creating SHA256 state hashes to ensure deterministic hashing and avoid duplicate notifications for semantically identical states.
+- Bump runtime dependencies: @push.rocks/smarthash -> ^3.2.6, @push.rocks/smartjson -> ^5.2.0.
+- Bump dev tooling versions: @git.zone/tsbuild -> ^2.6.8, @git.zone/tsbundle -> ^2.5.1, @git.zone/tstest -> ^2.3.8.
+- Add local .claude/settings.local.json configuration for allowed permissions (local tooling/settings file).
+
+## 2025-08-16 - 2.0.26 - fix(ci)
+Add local Claude settings file to allow helper permissions for common local commands
+
+- Added .claude/settings.local.json to grant local helper permissions for tooling
+- Allowed commands: Bash(tsx:*), Bash(tstest test:*), Bash(git add:*), Bash(git tag:*)
+- No changes to source code or runtime behavior; tooling/config only
+
+## 2025-07-29 - 2.0.25 - fix(core)

+# Smartstate Implementation Notes
+
+## Current API (as of v2.0.24+)
+
+### State Part Initialization
+- State parts can be created with different init modes: 'soft' (default), 'mandatory', 'force', 'persistent'
+  - 'soft' - returns existing state part if exists, creates new if not
+  - 'mandatory' - requires state part to not exist, fails if it does
+  - 'force' - always creates new state part, overwriting any existing
+  - 'persistent' - like 'soft' but with WebStore persistence (IndexedDB)
+- Persistent mode automatically calls init() internally - no need to call it manually
+- State merge order fixed: initial state takes precedence over stored state
+
+### Actions
+- Actions are created with `createAction()` method
+- Two ways to dispatch actions:
+  1. `stateAction.trigger(payload)` - returns Promise<TStatePayload>
+  2. `await statePart.dispatchAction(stateAction, payload)` - returns Promise<TStatePayload>
+- Both methods return the same Promise, providing flexibility in usage
+
+### State Management Methods
+- `select()` - returns Observable with startWith current state, filters undefined states
+- `waitUntilPresent()` - waits for specific state condition
+- `stateSetup()` - async state initialization with cumulative defer
+- `notifyChangeCumulative()` - defers notification to end of call stack
+- `getState()` - returns current state or undefined
+- `setState()` - validates state before setting, notifies only on actual changes
+
+### State Hash Detection
+- Uses SHA256 hash to detect actual state changes
+- Fixed: Hash comparison now properly awaits async hash calculation
+- Prevents duplicate notifications for identical state values
+- `notifyChange()` is now async to support proper hash comparison
+
+### State Validation
+- Basic validation ensures state is not null/undefined
+- `validateState()` method can be overridden in subclasses for custom validation
+- Validation runs on both setState() and when loading from persistent storage
+
+### Type System
+- Can use either enums or string literal types for state part names
+- Test uses simple string types: `type TMyStateParts = 'testStatePart'`
+- State can be undefined initially, handled properly in select() and other methods
+
+## Recent Fixes (v2.0.24+)
+1. Fixed state hash bug - now properly compares hash values instead of promises
+2. Fixed state initialization merge order - initial state now takes precedence
+3. Ensured stateStore is properly typed as potentially undefined
+4. Simplified init mode logic with clear behavior for each mode
+5. Added state validation with extensible validateState() method
+6. Made notifyChange() async to support proper hash comparison
+7. Updated select() to filter undefined states

 ## Usage
 
-Use TypeScript for best in class intellisense.
+The `@push.rocks/smartstate` library provides an elegant way to handle state within your JavaScript or TypeScript projects, leveraging the power of Reactive Extensions (RxJS) and a structured state management strategy. In the following sections, we will explore the comprehensive capabilities of this package and how to effectively use them in various scenarios, ensuring a robust state management pattern in your applications.
 
-## Contribution
+### Getting Started
 
-We are always happy for code contributions. If you are not the code contributing type that is ok. Still, maintaining Open Source repositories takes considerable time and thought. If you like the quality of what we do and our modules are useful to you we would appreciate a little monthly contribution: You can [contribute one time](https://lossless.link/contribute-onetime) or [contribute monthly](https://lossless.link/contribute). :)
+First, let's import the necessary components from the library:
 
-For further information read the linked docs at the top of this readme.
+```typescript
+import { Smartstate, StatePart, StateAction } from '@push.rocks/smartstate';
+```

-| By using this npm module you agree to our [privacy policy](https://lossless.gmbH/privacy)
+### Creating a SmartState Instance
+
+`Smartstate` acts as the container for your state parts. You can consider it as the root of your state management structure.
+
+```typescript
+const myAppSmartState = new Smartstate<YourStatePartNamesEnum>();
+```
+
+### Understanding Init Modes
+
+When creating state parts, you can specify different initialization modes:
+
+- **`'soft'`** (default) - Returns existing state part if it exists, creates new if not
+- **`'mandatory'`** - Requires state part to not exist, fails if it does
+- **`'force'`** - Always creates new state part, overwriting any existing one
+- **`'persistent'`** - Like 'soft' but with WebStore persistence using IndexedDB
+
+### Defining State Parts
+
+State parts represent separable sections of your state, making it easier to manage and modularize. For example, you may have a state part for user data and another for application settings. 
+
+Define state part names using either enums or string literal types:
+
+```typescript
+// Option 1: Using enums
+enum AppStateParts {
+  UserState = 'UserState',
+  SettingsState = 'SettingsState'
+}
+
+// Option 2: Using string literal types (simpler approach)
+type AppStateParts = 'UserState' | 'SettingsState';
+```
+
+Now, let's create a state part within our `myAppSmartState` instance:
+
+```typescript
+interface IUserState {
+  isLoggedIn: boolean;
+  username?: string;
+}
+
+const userStatePart = await myAppSmartState.getStatePart<IUserState>(
+  AppStateParts.UserState,
+  { isLoggedIn: false }, // Initial state
+  'soft' // Init mode (optional, defaults to 'soft')
+);
+
+// Note: Persistent state parts are automatically initialized internally
+```
+
+### Subscribing to State Changes
+
+You can subscribe to changes in a state part to perform actions accordingly:
+
+```typescript
+// The select() method automatically filters out undefined states
+userStatePart.select().subscribe((currentState) => {
+  console.log(`User Logged In: ${currentState.isLoggedIn}`);
+});
+```
+
+If you need to select a specific part of your state, you can pass a selector function:
+
+```typescript
+userStatePart.select(state => state.username).subscribe((username) => {
+  if (username) {
+    console.log(`Current user: ${username}`);
+  }
+});
+```
+
+### Modifying State with Actions
+
+Create actions to modify the state in a controlled manner:
+
+```typescript
+interface ILoginPayload {
+  username: string;
+}
+
+const loginUserAction = userStatePart.createAction<ILoginPayload>(async (statePart, payload) => {
+  return { ...statePart.getState(), isLoggedIn: true, username: payload.username };
+});
+
+// Dispatch the action to update the state
+loginUserAction.trigger({ username: 'johnDoe' });
+// or await the result
+const newState = await loginUserAction.trigger({ username: 'johnDoe' });
+```
+
+### Dispatching Actions
+
+There are two ways to dispatch actions:
+
+```typescript
+// Method 1: Using trigger on the action (returns promise)
+const newState = await loginUserAction.trigger({ username: 'johnDoe' });
+// or fire and forget
+loginUserAction.trigger({ username: 'johnDoe' });
+
+// Method 2: Using dispatchAction on the state part (returns promise)
+const newState = await userStatePart.dispatchAction(loginUserAction, { username: 'johnDoe' });
+```
+
+Both methods return a Promise with the new state, giving you flexibility in how you handle the result.
+
+### Additional State Methods
+
+`StatePart` provides several useful methods for state management:
+
+```typescript
+// Get current state (may be undefined initially)
+const currentState = userStatePart.getState();
+if (currentState) {
+  console.log('Current user:', currentState.username);
+}
+
+// Wait for a specific state condition
+await userStatePart.waitUntilPresent();
+
+// Wait for a specific property to be present
+await userStatePart.waitUntilPresent(state => state.username);
+
+// Setup initial state with async operations
+await userStatePart.stateSetup(async (statePart) => {
+  // Perform async initialization
+  const userData = await fetchUserData();
+  return { ...statePart.getState(), ...userData };
+});
+
+// Defer notification to end of call stack
+userStatePart.notifyChangeCumulative();
+```
+
+### Persistent State with WebStore
+
+`Smartstate` supports persistent states using WebStore (IndexedDB-based storage), allowing you to maintain state across sessions:
+
+```typescript
+const settingsStatePart = await myAppSmartState.getStatePart<ISettingsState>(
+  AppStateParts.SettingsState,
+  { theme: 'light' }, // Initial state
+  'persistent' // Mode
+);
+
+// Note: init() is called automatically for persistent mode
+```
+
+Persistent state automatically:
+- Saves state changes to IndexedDB
+- Restores state on application restart
+- Manages storage with configurable database and store names
+
+### State Validation
+
+`Smartstate` includes built-in state validation to ensure data integrity:
+
+```typescript
+// Basic validation (built-in)
+// Ensures state is not null or undefined
+await userStatePart.setState(null); // Throws error: Invalid state structure
+
+// Custom validation by extending StatePart
+class ValidatedStatePart<T> extends StatePart<string, T> {
+  protected validateState(stateArg: any): stateArg is T {
+    // Add your custom validation logic
+    return super.validateState(stateArg) && /* your validation */;
+  }
+}
+```
+
+### Performance Optimization
+
+`Smartstate` includes advanced performance optimizations:
+
+- **Async State Hash Detection**: Uses SHA256 hashing to detect actual state changes, preventing unnecessary notifications when state values haven't truly changed
+- **Duplicate Prevention**: Identical state updates are automatically filtered out
+- **Cumulative Notifications**: Batch multiple state changes into a single notification using `notifyChangeCumulative()`
+- **Selective Subscriptions**: Use selectors to subscribe only to specific state properties
+- **Undefined State Filtering**: The `select()` method automatically filters out undefined states
+
+### RxJS Integration
+
+`Smartstate` leverages RxJS for reactive state management:
+
+```typescript
+// State is exposed as an RxJS Subject
+const stateObservable = userStatePart.select();
+
+// Automatically starts with current state value
+stateObservable.subscribe((state) => {
+  console.log('Current state:', state);
+});
+
+// Use selectors for specific properties
+userStatePart.select(state => state.username)
+  .pipe(
+    distinctUntilChanged(),
+    filter(username => username !== undefined)
+  )
+  .subscribe(username => {
+    console.log('Username changed:', username);
+  });
+```
+
+### Complete Example
+
+Here's a comprehensive example showcasing the power of `@push.rocks/smartstate`:
+
+```typescript
+import { Smartstate, StatePart, StateAction } from '@push.rocks/smartstate';
+
+// Define your state structure
+type AppStateParts = 'user' | 'settings' | 'cart';
+
+interface IUserState {
+  isLoggedIn: boolean;
+  username?: string;
+  email?: string;
+}
+
+interface ICartState {
+  items: Array<{ id: string; quantity: number }>;
+  total: number;
+}
+
+// Create the smartstate instance
+const appState = new Smartstate<AppStateParts>();
+
+// Initialize state parts
+const userState = await appState.getStatePart<IUserState>('user', {
+  isLoggedIn: false
+});
+
+const cartState = await appState.getStatePart<ICartState>('cart', {
+  items: [],
+  total: 0
+}, 'persistent'); // Persists across sessions
+
+// Create actions
+const loginAction = userState.createAction<{ username: string; email: string }>(
+  async (statePart, payload) => {
+    // Simulate API call
+    await new Promise(resolve => setTimeout(resolve, 1000));
+    
+    return {
+      isLoggedIn: true,
+      username: payload.username,
+      email: payload.email
+    };
+  }
+);
+
+// Subscribe to changes
+userState.select(state => state.isLoggedIn).subscribe(isLoggedIn => {
+  console.log('Login status changed:', isLoggedIn);
+});
+
+// Dispatch actions
+await loginAction.trigger({ username: 'john', email: 'john@example.com' });
+```
+
