+# Changelog
+
+## 2026-02-27 - 2.0.31 - fix(deps)
+bump devDependencies and fix README license path
+
+- Bump @git.zone/tsbundle from ^2.8.3 to ^2.9.0
+- Bump @types/node from ^25.2.0 to ^25.3.2
+- Update documented dependency set/version to v2.0.30 in readme.hints.md
+- Fix README license file path from LICENSE to license in readme.md
+
+## 2026-02-02 - 2.0.30 - fix(config)
+update npmextra configuration and improve README: rename package keys, add release registry config, clarify waitUntilPresent timeout and notification/persistence behavior
+
+- Renamed npmextra keys: 'gitzone' → '@git.zone/cli' and 'tsdoc' → '@git.zone/tsdoc'
+- Added release configuration for @git.zone/cli including registries (verdaccio and npm) and accessLevel
+- Removed top-level 'npmci' section
+- Added new '@ship.zone/szci' entry with npmGlobalTools
+- README: added waitUntilPresent timeout example with error handling
+- README: clarified notifyChangeCumulative is debounced and documented persistence behavior (merge with defaults, atomic writes)
+- README: documented concurrency/race-condition safety and timeout support for waitUntilPresent
+
+## 2026-02-02 - 2.0.29 - fix(smartstate)
+prevent duplicate statepart creation and fix persistence/notification race conditions
+
+- Add pendingStatePartCreation map to deduplicate concurrent createStatePart calls
+- Adjust init handling so 'force' falls through to creation and concurrent creations are serialized
+- Merge persisted state with initial payload in 'persistent' initMode, with persisted values taking precedence
+- Persist to WebStore before updating in-memory state to ensure atomicity
+- Debounce cumulative notifications via pendingCumulativeNotification to avoid duplicate notifications
+- Log selector errors instead of silently swallowing exceptions
+- Add optional timeout to waitUntilPresent and ensure subscriptions and timeouts are cleaned up to avoid indefinite waits
+- Await setState when performing chained state updates to ensure ordering and avoid race conditions
+
+## 2026-02-02 - 2.0.28 - fix(deps)
+bump devDependencies and dependencies, add tsbundle build config, update docs, and reorganize tests
+
+- Bumped @git.zone/tsbuild to ^4.1.2, @git.zone/tsbundle to ^2.8.3, @git.zone/tsrun to ^2.0.1, @git.zone/tstest to ^3.1.8, and @types/node to ^25.2.0
+- Upgraded @push.rocks/smartjson to ^6.0.0
+- Added @git.zone/tsbundle bundle configuration to npmextra.json for building a dist bundle
+- Removed pnpm-workspace.yaml entries (cleaned workspace constraints)
+- Updated readme and readme.hints (docs formatting, version bumped to v2.0.28, issue reporting/security section and dependency list)
+- Reorganized tests: removed *.both.ts variants and added consolidated test files under test/ (test.ts, test.initialization.ts)
+
+## 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)
+Major state initialization and validation improvements
+
+- Fixed state hash bug: Now properly compares hash values instead of storing state objects
+- Fixed state initialization merge order: Initial state now correctly takes precedence over stored state

+- Added comprehensive test suite for state initialization scenarios
+- Updated documentation with clearer examples and improved readme
+

+# Smartstate Implementation Notes
+
+## Current API (as of v2.0.28+)
+
+### 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
+

-[![repo-footer](https://lossless.gitlab.io/publicrelations/repofooter.svg)](https://maintainedby.lossless.com)
+`Smartstate` acts as the container for your state parts. Think of 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:
+
+| Mode | Description |
+|------|-------------|
+| `'soft'` | Default. Returns existing state part if it exists, creates new if not |
+| `'mandatory'` | Requires state part to not exist, throws error 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. 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';
+```
+
+Create a state part within your `Smartstate` 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')
+);
+```
+
+### Subscribing to State Changes
+
+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}`);
+});
+```
+
+Select a specific part of your state with 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
+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' });
+
+// 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 payload.
+
+### 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 state to be present
+await userStatePart.waitUntilPresent();
+
+// Wait for a specific property to be present
+await userStatePart.waitUntilPresent(state => state.username);
+
+// Wait with a timeout (throws error if condition not met within timeout)
+try {
+  await userStatePart.waitUntilPresent(state => state.username, 5000); // 5 second timeout
+} catch (error) {
+  console.error('Timed out waiting for username');
+}
+
+// Setup initial state with async operations
+await userStatePart.stateSetup(async (statePart) => {
+  const userData = await fetchUserData();
+  return { ...statePart.getState(), ...userData };
+});
+
+// Defer notification to end of call stack (debounced)
+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/default state
+  'persistent' // Mode
+);
+```
+
+Persistent state automatically:
+- Saves state changes to IndexedDB
+- Restores state on application restart
+- Merges persisted values with defaults (persisted values take precedence)
+- Ensures atomic writes (persistence happens before memory update)
+
+### 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 {
+    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()` with automatic debouncing
+- **🎯 Selective Subscriptions**: Use selectors to subscribe only to specific state properties
+- **✨ Undefined State Filtering**: The `select()` method automatically filters out undefined states
+- **⚡ Concurrent Access Safety**: Prevents race conditions when multiple calls request the same state part simultaneously
+
+### 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' });
+```
