-## Domain Knowledge and Repository Queries
-
-Business rules like expiration checks (`expirationDate <= currentDate`) represent domain knowledge that **must have a single source of truth**. This logic might evolve (e.g., to `<= currentDate - N days` or vary by item type) and should never be duplicated across the codebase.
-
-While simple predicates (like `findWhere(predicate<bool>(Item))`) work for in-memory repositories, SQL-based repositories need to translate these rules into efficient WHERE clauses. One solution (not too over-engineered) would be to pass DTO or value object ready to be put into queries (e.g., `fetchExpiredItems(calculatedConditionFields)`).
-
-But for fun and possible UI search, consider implementing a specification pattern with a simple condition abstraction that exposes the business rule as composable conditions (field, operator, value).
-
-This allows domain services to define rules once, use cases to apply them consistently, and repositories to translate them into optimal queries by interpreting the conditions according to their storage mechanism. Avoid duplicating the business logic in repository implementations - instead, let repositories consume the specification and build their queries accordingly. This aims to overcome to-repo-and-back drawbacks depicted in *Evans, Eric (2003). Domain Driven Design. Final Manuscript*.

-# Specification Pattern Implementation
-
-The Specification pattern allows you to encapsulate business logic for filtering and querying data. Instead of writing SQL queries directly, you build specifications using Go code that can later be converted to SQL, used for in-memory filtering, or other purposes.
-
-## Core Components
-
-### 1. Basic Data Structures (`condition_spec.go`)
-
-#### `Condition`
-Represents a single comparison operation:
-```go
-type Condition struct {
-    Field    string      // Field name (e.g., "age", "name")
-    Operator string      // Comparison operator (e.g., "=", ">", "IN")
-    Value    interface{} // Value to compare against
-}
-```
-
-#### `LogicalGroup`
-Combines multiple conditions with logical operators:
-```go
-type LogicalGroup struct {
-    Operator   string      // "AND", "OR", or "NOT"
-    Conditions []Condition // Simple conditions
-    Spec       *Spec       // Nested specification for complex logic
-}
-```
-
-#### `Spec`
-The main specification container (can hold either a single condition or a logical group):
-```go
-type Spec struct {
-    Condition    *Condition    // For simple conditions
-    LogicalGroup *LogicalGroup // For complex logic
-}
-```
-
-### 2. Builder Functions
-
-These functions create specifications in a fluent, readable way:
-
-```go
-// Simple conditions
-userSpec := Eq("name", "John")           // name = "John"
-ageSpec := Gt("age", 18)                 // age > 18
-roleSpec := In("role", []interface{}{"admin", "moderator"}) // role IN ("admin", "moderator")
-
-// Logical combinations
-complexSpec := And(
-    Eq("status", "active"),
-    Or(
-        Gt("age", 21),
-        Eq("role", "admin"),
-    ),
-)
-```
-
-### 3. Specification Interface (`simple_specification.go`)
-
-The `Specification[T]` interface provides methods for:
-- **Evaluation**: `IsSatisfiedBy(candidate T) bool`
-- **Composition**: `And()`, `Or()`, `Not()`
-- **Introspection**: `GetConditions()`, `GetSpec()`
-
-## How It Works
-
-### 1. Building Specifications
-
-```go
-// Create a specification for active users over 18
-spec := And(
-    Eq("status", "active"),
-    Gt("age", 18),
-)
-```
-
-### 2. Evaluating Specifications
-
-The `SimpleSpecification` uses reflection to evaluate conditions against Go objects:
-
-```go
-user := &User{Name: "John", Age: 25, Status: "active"}
-specification := NewSimpleSpecification[*User](spec)
-isMatch := specification.IsSatisfiedBy(user) // true
-```
-
-### 3. Field Access
-
-The implementation looks for field values in this order:
-1. `GetFieldName()` method (e.g., `GetAge()`)
-2. `FieldName()` method (e.g., `Age()`)
-3. Exported struct field
-
-### 4. Type Comparisons
-
-The system handles different data types intelligently:
-- **Numbers**: Direct comparison with type conversion
-- **Strings**: Lexicographic comparison
-- **Time**: Special handling for `time.Time` and objects with `Time()` methods
-- **Collections**: `IN` and `NOT IN` operations
-- **Nil values**: Proper null handling
-
-## Examples
-
-### Simple Usage
-```go
-// Find all active users
-activeSpec := Eq("status", "active")
-spec := NewSimpleSpecification[*User](activeSpec)
-
-users := []User{{Status: "active"}, {Status: "inactive"}}
-for _, user := range users {
-    if spec.IsSatisfiedBy(&user) {
-        fmt.Println("Active user:", user.Name)
-    }
-}
-```
-
-### Complex Logic
-```go
-// Find admin users OR users with high scores
-complexSpec := Or(
-    Eq("role", "admin"),
-    And(
-        Gt("score", 90),
-        Eq("status", "active"),
-    ),
-)
-```
-
-### Time Comparisons
-```go
-// Find expired items
-expiredSpec := Lte("expirationDate", time.Now())
-```
-
-## Key Benefits
-
-1. **Type Safety**: Compile-time checking with generics
-2. **Readability**: Business logic expressed in readable Go code
-3. **Reusability**: Specifications can be composed and reused
-4. **Testability**: Easy to test business rules in isolation
-5. **Flexibility**: Can be converted to SQL, used for filtering, etc.
-
-## Performance Considerations
-
-- Reflection is used for field access (consider caching for high-frequency operations)
-- Complex nested specifications may impact performance
-- Time comparisons handle multiple formats but may be slower than direct comparisons
-
-## Common Patterns
-
-### Repository Integration
-```go
-type UserRepository interface {
-    FindWhere(ctx context.Context, spec Specification[*User]) ([]*User, error)
-}
-```
-
-### Business Rule Encapsulation
-```go
-func ActiveUserSpec() *Spec {
-    return And(
-        Eq("status", "active"),
-        Neq("deletedAt", nil),
-    )
-}
-```
-
-### Dynamic Query Building
-```go
-func BuildUserSearchSpec(filters UserFilters) *Spec {
-    conditions := []*Spec{}
-
-    if filters.Status != "" {
-        conditions = append(conditions, Eq("status", filters.Status))
-    }
-    if filters.MinAge > 0 {
-        conditions = append(conditions, Gte("age", filters.MinAge))
-    }
-
-    return And(conditions...)

-# NestJS Implementation Plan for AutoStore
-
-## Overview
-Implementation of AutoStore system using NestJS with TypeScript, following Clean Architecture principles. The system stores items with expiration dates and automatically orders new items when they expire.
-
-## Architecture Approach
-- **Clean Architecture** with clear separation of concerns
-- **Domain-Driven Design** with rich domain models
-- **Hexagonal Architecture** with dependency inversion
-- **Repository Pattern** for data persistence
-- **CQRS-like** command/query separation
-- **Dependency Injection** leveraging NestJS IoC container
-
-## Core Domain Logic
-
-### ItemExpirationSpec - Single Source of Truth for Expiration
-
-**File**: `src/domain/specifications/item-expiration.spec.ts`
-**Purpose**: Centralized expiration checking logic - the single source of truth for determining if items are expired
-
-**Key Methods**:
-- `isExpired(item: ItemEntity, currentTime: Date): boolean` - Checks if item expired
-- `getSpec(currentTime: Date): Specification<ItemEntity>` - Returns specification for repository queries
-
-**Place in the flow**:
-- Called by `AddItemCommand.execute()` to check newly created items for immediate expiration
-- Called by `HandleExpiredItemsCommand.execute()` to find expired items for processing
-- Used by `ItemRepository.findWhere()` to query database for expired items
-
-## Detailed Implementation Plan
-
-### Domain Layer
-
-#### 1. Entities
-
-**File**: `src/domain/entities/item.entity.ts`
-**Purpose**: Core business entity representing an item
-
-**Key Methods**:
-- `constructor(id: ItemId, name: string, expirationDate: ExpirationDate, orderUrl: string, userId: UserId): void` - Creates item with validation
-- Getters for all properties
-
-**Place in the flow**:
-- Created by `AddItemCommand.execute()`
-- Retrieved by `ItemRepository` methods
-- Passed to `ItemExpirationSpec.isExpired()` for expiration checking
-
-**File**: `src/domain/entities/user.entity.ts`
-**Purpose**: User entity for item ownership and authentication purposes
-
-**Key Methods**:
-- `constructor(id: UserId, username: string, passwordHash: string): void` - Creates user with validation
-- Getters for all properties
-
-#### 2. Value Objects
-
-**File**: `src/domain/value-objects/item-id.vo.ts`
-**Purpose**: Strong typing for item identifiers
-
-**Key Methods**:
-- `constructor(value: string): void` - Validates UUID format
-- `getValue(): string` - Returns string value
-- `equals(other: ItemId): boolean` - Compares with another ItemId
-
-**File**: `src/domain/value-objects/expiration-date.vo.ts`
-**Purpose**: Immutable expiration date with validation
-
-**Key Methods**:
-- `constructor(value: Date): void` - Validates date format (allows past dates per business rules)
-- `getValue(): Date` - Returns Date object
-- `format(): string` - Returns ISO string format
-
-**Place in the flow**:
-- Used by `ItemEntity` constructor for type-safe date handling
-- Validated by `ItemExpirationSpec.isExpired()` for expiration logic
-
-#### 3. Specifications
-
-**File**: `src/domain/specifications/specification.interface.ts`
-**Purpose**: Generic specification pattern interface
-
-**Key Methods**:
-- `isSatisfiedBy(candidate: T): boolean` - Evaluates specification
-- `getSpec(): object` - Returns specification object for repository implementation
-
-**Place in the flow**:
-- Implemented by `ItemExpirationSpec` for type-safe specifications
-- Used by `ItemRepository.findWhere()` for database queries
-
-### Application Layer
-
-#### 4. Commands
-
-**File**: `src/application/commands/add-item.command.ts`
-**Purpose**: Use case for creating new items with expiration handling
-
-**Key Methods**:
-- `constructor(itemRepo: IItemRepository, orderService: IOrderService, timeProvider: ITimeProvider, expirationSpec: ItemExpirationSpec, logger: Logger): void` - Dependency injection
-- `execute(name: string, expirationDate: string, orderUrl: string, userId: string): Promise<string | null>` - Creates item, handles expired items immediately
-
-**Flow**:
-1. `ItemsController.createItem()` calls `AddItemCommand.execute()`
-2. Creates `ItemEntity` with validated data
-3. Calls `ItemExpirationSpec.isExpired()` to check if item is expired
-4. If expired:
-   - calls `OrderHttpService.orderItem()`
-   - **returns item ID** (business rule: expired items trigger ordering but still return ID field that might be empty or invalid)
-5. If not expired: calls `ItemRepository.save()` and returns item ID
-
-**File**: `src/application/commands/handle-expired-items.command.ts`
-**Purpose**: Background command to process expired items
-
-**Key Methods**:
-- `constructor(itemRepo: IItemRepository, orderService: IOrderService, timeProvider: ITimeProvider, expirationSpec: ItemExpirationSpec, logger: Logger): void` - Dependency injection
-- `execute(): Promise<void>` - Finds and processes all expired items
-
-**Flow**:
-1. `ExpiredItemsScheduler.handleCron()` calls `HandleExpiredItemsCommand.execute()`
-2. Gets current time from `ITimeProvider`
-3. Calls `ItemExpirationSpec.getSpec()` to get expiration specification
-4. Calls `ItemRepository.findWhere()` to find expired items
-5. For each expired item: calls `OrderHttpService.orderItem()` then `ItemRepository.delete()`
-
-**File**: `src/application/commands/delete-item.command.ts`
-**Purpose**: Use case for deleting user items
-
-**Key Methods**:
-- `constructor(itemRepo: IItemRepository, logger: Logger): void` - Dependency injection
-- `execute(itemId: string, userId: string): Promise<void>` - Validates ownership and deletes item
-
-**Flow**:
-1. `ItemsController.deleteItem()` calls `DeleteItemCommand.execute()`
-2. Calls `ItemRepository.findById()` to retrieve item
-3. Validates ownership by comparing user IDs
-4. Calls `ItemRepository.delete()` to remove item
-
-**File**: `src/application/commands/login-user.command.ts`
-**Purpose**: User authentication use case
-
-**Key Methods**:
-- `constructor(authService: IAuthService, logger: Logger): void` - Dependency injection
-- `execute(username: string, password: string): Promise<string>` - Authenticates and returns JWT token
-
-#### 5. Queries
-
-**File**: `src/application/queries/get-item.query.ts`
-**Purpose**: Retrieves single item by ID with authorization
-
-**Key Methods**:
-- `constructor(itemRepo: IItemRepository, logger: Logger): void` - Dependency injection
-- `execute(itemId: string, userId: string): Promise<ItemEntity>` - Validates ownership and returns item
-
-**Flow**:
-1. `ItemsController.getItem()` calls `GetItemQuery.execute()`
-2. Calls `ItemRepository.findById()` to retrieve item
-3. Validates ownership by comparing user IDs
-4. Returns item entity
-
-**File**: `src/application/queries/list-items.query.ts`
-**Purpose**: Retrieves all items for authenticated user
-
-**Key Methods**:
-- `constructor(itemRepo: IItemRepository, logger: Logger): void` - Dependency injection
-- `execute(userId: string): Promise<ItemEntity[]>` - Returns user's items
-
-**Flow**:
-1. `ItemsController.listItems()` calls `ListItemsQuery.execute()`
-2. Calls `ItemRepository.findByUserId()` to retrieve user's items
-3. Returns array of item entities
-
-#### 6. DTOs
-
-**File**: `src/application/dto/create-item.dto.ts`
-**Purpose**: Request validation for item creation
-
-**Key Properties**:
-- `name: string` - Item name (min: 1, max: 255)
-- `expirationDate: string` - ISO date string (future date validation)
-- `orderUrl: string` - Valid URL format
-
-**Place in the flow**:
-- Used by `ItemsController.createItem()` for request body validation
-
-**File**: `src/application/dto/item-response.dto.ts`

-4. **Separation of Concerns**: Each layer has distinct responsibilities
-5. **Testability**: All components can be tested in isolation
-
-This implementation plan ensures consistent development regardless of the implementer, providing clear flow definitions and emphasizing `ItemExpirationSpec` as the centralized source for expiration logic.

-# NestJS Implementation Review
-
-## Overview
-
-This review analyzes the TypeScript + NestJS implementation of the AutoStore application, focusing on adherence to Clean Architecture principles, SOLID principles, and the critical requirement of maintaining a **single source of truth** for domain knowledge.
-
-## Architecture Assessment
-
-### ✅ Strengths
-
-#### 1. Clean Architecture Implementation
-The implementation successfully follows Clean Architecture with clear layer separation:
-
-- **Domain Layer**: Pure business logic with entities, value objects, and specifications
-- **Application Layer**: Use cases, commands, queries, and infrastructure interfaces
-- **Infrastructure Layer**: Concrete implementations (repositories, HTTP services, auth)
-- **Presentation Layer**: Controllers and API endpoints
-
-#### 2. Specification Pattern Implementation
-**Excellent implementation** of the Specification pattern for maintaining single source of truth:
-
-```typescript
-// Domain specification - SINGLE SOURCE OF TRUTH
-export class ItemExpirationSpec {
-  isExpired(item: ItemEntity, currentTime: Date): boolean {
-    return this.getSpec(currentTime).match(item);
-  }
-
-  getSpec(currentTime: Date): SimpleSpecification<ItemEntity> {
-    return new SimpleSpecification<ItemEntity>(
-      Spec.lte('expirationDate', currentTime.toISOString())
-    );
-  }
-}
-```
-
-This ensures that the expiration logic (`date <= now`) is defined **only once** in the domain layer and reused throughout the application.
-
-#### 3. Value Objects and Entities
-Proper implementation of Domain-Driven Design patterns:
-- **Value Objects**: [`ItemId`](src/domain/value-objects/item-id.vo.ts:1), [`UserId`](src/domain/value-objects/user-id.vo.ts:1), [`ExpirationDate`](src/domain/value-objects/expiration-date.vo.ts:1)
-- **Entities**: [`ItemEntity`](src/domain/entities/item.entity.ts:1) with proper encapsulation
-- **Immutability**: Value objects are immutable with defensive copying
-
-#### 4. Dependency Inversion
-Excellent use of dependency injection and interface segregation:
-
-```typescript
-// Application layer depends on abstractions
-export interface IItemRepository {
-  findWhere(specification: ISpecification<ItemEntity>): Promise<ItemEntity[]>;
-  // ... other methods
-}
-```
-
-#### 5. Repository Pattern with Specifications
-The [`FileItemRepository`](src/infrastructure/repositories/file-item-repository.ts:114) properly implements the specification pattern:
-
-```typescript
-async findWhere(specification: ISpecification<ItemEntity>): Promise<ItemEntity[]> {
-  // Uses domain specifications for filtering
-  if (specification.isSatisfiedBy(item)) {
-    matchingItems.push(item);
-  }
-}
-```
-
-#### 6. Background Processing
-The implementation now includes background processing using NestJS's built-in scheduler:
-
-**New Implementation**: [`ExpiredItemsSchedulerService`](src/infrastructure/services/expired-items-scheduler.service.ts:1)
-- **On startup**: Immediately processes expired items via `onModuleInit()`
-- **Every minute**: Runs via `@Cron(CronExpression.EVERY_MINUTE)`
-- **Daily at midnight**: Runs via `@Cron('0 0 * * *')` for daily processing
-- **Robust error handling**: Continues operation despite individual processing failures
-- **Comprehensive logging**: Tracks all scheduling activities
-
-**Flow Integration**:
-```
-AppModule → ScheduleModule.forRoot() → ExpiredItemsSchedulerService
-    ↓
-onModuleInit() → HandleExpiredItemsCommand.execute() [startup]
-    ↓
-@Cron(EVERY_MINUTE) → HandleExpiredItemsCommand.execute() [continuous]
-    ↓
-@Cron('0 0 * * *') → HandleExpiredItemsCommand.execute() [daily midnight]
-```
-
-### 🔍 Areas for Improvement
-
-#### 1. Framework Dependency in Application Layer
-The implementation intentionally violates the Clean Architecture principle of framework-independent application layer by using NestJS decorators (`@Injectable()`, `@Inject()`) in the application layer. This decision was made for several practical reasons:
-
-- **Cleaner Construction**: NestJS's dependency injection system provides a clean and declarative way to manage dependencies, making the construction part of the application more maintainable and readable.
-- **Ecosystem Integration**: Leveraging NestJS's native DI system allows for better integration with the framework's features, including interceptors, guards, and lifecycle hooks.
-- **Community Standards**: This approach follows common practices in the NestJS community, making the code more familiar to developers experienced with the framework.
-- **Testing Support**: NestJS provides excellent testing utilities that work seamlessly with decorator-based dependency injection.
-
-While this does create a framework dependency in the application layer, the trade-off is considered worthwhile for the benefits it provides in terms of development speed, maintainability, and framework integration. Alternative approaches like the Adapter Pattern or Factory Pattern could be used to make the application layer truly framework-agnostic, but they would introduce additional complexity and boilerplate code.
-
-#### 2. Specification Pattern Consistency
-
-While the implementation is excellent, there's a minor inconsistency in the [`ItemExpirationSpec`](src/domain/specifications/item-expiration.spec.ts:4) class name. The file is named `item-expiration.spec.ts` but the class is `ItemExpirationSpec`. Consider renaming to `ItemExpirationSpecification` for consistency.
-
-#### 3. Error Handling
-The application could benefit from custom domain exceptions instead of generic `Error` objects:
-
-```typescript
-// Current approach
-throw new Error('Item name cannot be empty');
-
-// Suggested improvement
-throw new InvalidItemNameException('Item name cannot be empty');
-```
-
-#### 4. Domain Events
-Consider implementing domain events for the ordering process to better separate concerns:
-
-```typescript
-// Instead of direct ordering in command
-await this.orderService.orderItem(item);
-
-// Consider domain events
-domainEvents.publish(new ItemExpiredEvent(item));
-```
-
-
-
-
-### 🎯 Comparison with PHP and C++ Implementations
-
-#### PHP Implementation
-The PHP implementation follows a similar specification pattern but with some differences:
-
-```php
-// PHP specification
-public function isExpired(Item $item, DateTimeImmutable $currentTime): bool
-{
-    return $this->getSpec($currentTime)->match($item);
-}
-
-public function getSpec(DateTimeImmutable $currentTime): Specification
-{
-    return new Specification(
-        Spec::lte('expirationDate', $currentTime->format('Y-m-d H:i:s'))
-    );
-}
-```
-
-**Key Differences:**
-- PHP uses `DateTimeImmutable` vs TypeScript's `Date`
-- PHP specification includes SQL rendering capabilities in comments
-- Both maintain single source of truth effectively
-
-#### C++ Implementation
-The C++ implementation uses a different approach with a policy pattern:
-
-```cpp
-// C++ policy approach
-bool isExpired(const Item& item, const TimePoint& currentTime) const
-{
-    return item.expirationDate <= currentTime;
-}
-
-ItemExpirationSpec getExpiredSpecification(const TimePoint& currentTime) const
-{
-    return nxl::helpers::SpecificationBuilder()
-        .field(FIELD_EXP_DATE)
-        .lessOrEqual(currentTime)
-        .build();
-}
-```
-
-**Key Differences:**
-- C++ uses `std::chrono::system_clock::time_point`
-- C++ uses a builder pattern for specifications
-- Direct comparison in `isExpired` vs specification-based approach
-
-### 🏆 Best Practices Demonstrated
-
-#### 1. Single Source of Truth
-**Excellent adherence** to the requirement that expiration checking logic exists in only one place:
-
-- ✅ Domain specification defines `expirationDate <= currentTime` logic
-- ✅ Application layer uses [`ItemExpirationSpec`](src/application/commands/handle-expired-items.command.ts:18) for business logic
-- ✅ Repository layer uses specifications for filtering without duplicating logic
-- ✅ No hardcoded expiration logic in controllers or infrastructure
-
-#### 2. SOLID Principles
-
-**Single Responsibility Principle**: Each class has one reason to change
-- [`ItemEntity`](src/domain/entities/item.entity.ts:5): Manages item state and validation
-- [`ItemExpirationSpec`](src/domain/specifications/item-expiration.spec.ts:4): Manages expiration logic
-- [`FileItemRepository`](src/infrastructure/repositories/file-item-repository.ts:12): Manages persistence
-
-**Open/Closed Principle**: Extension through specifications, not modification
-- New filtering criteria can be added via new specifications
-- Repository doesn't need modification for new query types
-
-**Liskov Substitution Principle**: Interfaces are properly segregated
-- [`IItemRepository`](src/application/interfaces/item-repository.interface.ts:6) can be implemented by any storage mechanism
-
-**Interface Segregation Principle**: Focused interfaces
-- [`ITimeProvider`](src/application/interfaces/time-provider.interface.ts:1): Single method interface
-- [`IOrderService`](src/application/interfaces/order-service.interface.ts:1): Focused on ordering
-
-**Dependency Inversion Principle**: Dependencies on abstractions
-- Application layer depends on interfaces, not concrete implementations
-
-#### 3. Clean Architecture Boundaries
-
-**Domain Layer**: No external dependencies
-- Pure TypeScript with no framework imports
-- Business logic isolated from infrastructure concerns
-
-**Application Layer**: Orchestrates use cases
-- Depends only on domain layer and infrastructure interfaces
-- Commands and queries properly separated
-
-**Infrastructure Layer**: Implements abstractions
-- [`FileItemRepository`](src/infrastructure/repositories/file-item-repository.ts:12) implements [`IItemRepository`](src/application/interfaces/item-repository.interface.ts:6)
-- [`SystemTimeProvider`](src/infrastructure/services/system-time.provider.ts:5) implements [`ITimeProvider`](src/application/interfaces/time-provider.interface.ts:1)
-
-### 🧪 Testing Quality
-
-The implementation includes comprehensive tests:
-- **Unit tests** for specifications with edge cases
-- **Integration tests** for repositories
-- **Boundary testing** for date/time scenarios
-- **Specification testing** to ensure single source of truth
-
-### 🚀 Recommendations
-
-1. **Maintain the Specification Pattern**: This is the strongest aspect of the implementation
-2. **Consider Domain Events**: For better separation of ordering concerns
-3. **Add Custom Exceptions**: For better error handling and domain expressiveness
-4. **Document Business Rules**: Add comments explaining why expired items are allowed (business requirement)
-
-## Conclusion
-
-The NestJS implementation **excellently demonstrates** Clean Architecture principles and successfully maintains a **single source of truth** for domain knowledge. The specification pattern implementation is particularly strong, ensuring that expiration date checking logic (`date <= now`) exists in exactly one place in the codebase.
-
-The architecture properly separates concerns, follows SOLID principles, and provides a solid foundation for the AutoStore application. The comparison with PHP and C++ implementations shows that while the technical details differ, all implementations successfully maintain the critical single source of truth requirement.
