Here’s the refactored authentication module using claude-code-zed in Zed:

```typescript
// src/auth/types.ts
interface User {
  id: string;
  email: string;
  roles: string[];
}

interface AuthState {
  user: User | null;
  token: string | null;
  loading: boolean;
}

// src/auth/authService.ts
class AuthService {
  private async validateToken(token: string): Promise<User> {
    const response = await fetch('/api/validate', {
      headers: { Authorization: `Bearer ${token}` }
    });
    if (!response.ok) throw new Error('Invalid token');
    return response.json();
  }

  async login(email: string, password: string): Promise<AuthState> {
    const response = await fetch('/api/login', {
      method: 'POST',
      body: JSON.stringify({ email, password })
    });
    const { token } = await response.json();
    const user = await this.validateToken(token);
    return { user, token, loading: false };
  }
}
```

Changes applied:
1. Added TypeScript interfaces for `User` and `AuthState` to enforce type safety.
2. Refactored `AuthService` to use async/await for token validation.
3. Updated the login method to return a properly typed `AuthState`.

The Zed editor shows no errors in the TypeScript compilation, and the changes are reflected in the workspace files. To test, run `npm run dev` and verify the login flow works as expected.
