V3 Core Implementation

# V3 Core Implementation

## What This Skill Does

Implements the core TypeScript modules for claude-flow v3 following Domain-Driven Design principles, clean architecture patterns, and modern TypeScript best practices with comprehensive test coverage.

## Quick Start

```bash
# Initialize core implementation
Task("Core foundation", "Set up DDD domain structure and base classes", "core-implementer")

# Domain implementation (parallel)
Task("Task domain", "Implement task management domain with entities and services", "core-implementer")
Task("Session domain", "Implement session management domain", "core-implementer")
Task("Health domain", "Implement health monitoring domain", "core-implementer")
```

## Base Domain Classes

### Entity Base Class
```typescript
// src$core$shared$domain$entity.ts
export abstract class Entity<T> {
  protected readonly _id: T;
  private _domainEvents: DomainEvent[] = [];

  constructor(id: T) {
    this._id = id;
  }

  get id(): T {
    return this._id;
  }

  public equals(object?: Entity<T>): boolean {
    if (object == null || object == undefined) {
      return false;
    }

    if (this === object) {
      return true;
    }

    if (!(object instanceof Entity)) {
      return false;
    }

    return this._id === object._id;
  }

  protected addDomainEvent(domainEvent: DomainEvent): void {
    this._domainEvents.push(domainEvent);
  }

  public getUncommittedEvents(): DomainEvent[] {
    return this._domainEvents;
  }

  public markEventsAsCommitted(): void {
    this._domainEvents = [];
  }
}
```

### Value Object Base Class
```typescript
// src$core$shared$domain$value-object.ts
export abstract class ValueObject<T> {
  protected readonly props: T;

  constructor(props: T) {
    this.props = Object.freeze(props);
  }

  public equals(object?: ValueObject<T>): boolean {
    if (object == null || object == undefined) {
      return false;
    }

    if (this === object) {
      return true;
    }

    return JSON.stringify(this.props) === JSON.stringify(object.props);
  }

  get value(): T {
    return this.props;
  }
}
```

### Aggregate Root
```typescript
// src$core$shared$domain$aggregate-root.ts
export abstract class AggregateRoot<T> extends Entity<T> {
  private _version: number = 0;

  get version(): number {
    return this._version;
  }

  protected incrementVersion(): void {
    this._version++;
  }

  public applyEvent(event: DomainEvent): void {
    this.addDomainEvent(event);
    this.incrementVersion();
  }
}
```
