- two_factor_recovery_codes (text, nullable)
- two_factor_confirmed_at (timestamp, nullable)
- remember_token (string, nullable)
- created_at, updated_at (timestamps)
```

**consultations**:
```
- id (bigint, PK)
- user_id (bigint, FK -> users.id, cascade delete)
- booking_date (date)
- booking_time (time)
- problem_summary (text)

INDEX: booking_date, user_id
```

**timelines**:
```
- id (bigint, PK)
- user_id (bigint, FK -> users.id, cascade delete)
- case_name (string)
- case_reference (string, nullable, unique)

```

**working_hours**:

- created_at, updated_at (timestamps)
```

**blocked_times**:
```

- block_date (date)
- start_time (time, nullable) - null means full day
- end_time (time, nullable) - null means full day
- reason (string, nullable)

```

**notifications** (custom, NOT Laravel's built-in):
```

### Foreign Key Constraints
| Column | References | On Delete |
|--------|------------|-----------|
| consultations.user_id | users.id | CASCADE |
| timelines.user_id | users.id | CASCADE |
| timeline_updates.timeline_id | timelines.id | CASCADE |
| timeline_updates.admin_id | users.id | CASCADE |
| notifications.user_id | users.id | CASCADE |
| admin_logs.admin_id | users.id | CASCADE |

### Enum Definitions (from Architecture Section 4)

```php
// app/Enums/UserType.php
enum UserType: string {
    case Admin = 'admin';
    case Individual = 'individual';
    case Company = 'company';
}

// app/Enums/UserStatus.php
enum UserStatus: string {
    case Active = 'active';
    case Deactivated = 'deactivated';
}

// app/Enums/ConsultationType.php
enum ConsultationType: string {
    case Free = 'free';
    case Paid = 'paid';
}

// app/Enums/ConsultationStatus.php
enum ConsultationStatus: string {
    case Pending = 'pending';
    case Approved = 'approved';
    case Rejected = 'rejected';
    case Completed = 'completed';
    case NoShow = 'no_show';
    case Cancelled = 'cancelled';
}

// app/Enums/PaymentStatus.php
enum PaymentStatus: string {
    case Pending = 'pending';
    case Received = 'received';
    case NotApplicable = 'na';
}

// app/Enums/TimelineStatus.php
enum TimelineStatus: string {
    case Active = 'active';
    case Archived = 'archived';
}

// app/Enums/PostStatus.php
enum PostStatus: string {
    case Draft = 'draft';
    case Published = 'published';
}
```

### Technical Standards
- **Database:** SQLite for development (`DB_CONNECTION=sqlite`)
- **Pattern:** Class-based Volt components
- **Structure:** Laravel 12 streamlined (no app/Http/Middleware, use bootstrap/app.php)
- **Models:** Create with `php artisan make:model ModelName -mf`
- **Enums:** Use PHP 8.1+ backed enums with string values

### Testing

**Test Location:** `tests/Unit/` and `tests/Feature/Database/`

**Testing Framework:** Pest 4
- Create tests with: `php artisan make:test TestName --pest`
- Run tests with: `php artisan test`

**Required Tests:**
1. Migration tests - verify `migrate:fresh` and `migrate:rollback` work
2. Factory tests - verify each factory creates valid models
3. Enum validation tests - verify models reject invalid enum values
4. Relationship tests - verify foreign keys and Eloquent relationships work
5. JSON field tests - verify JSON columns store/retrieve correctly

**Test Patterns:**
```php
// Example factory test
test('consultation factory creates valid consultation', function () {
    $consultation = Consultation::factory()->create();

    expect($consultation)->toBeInstanceOf(Consultation::class)
        ->and($consultation->user)->toBeInstanceOf(User::class)
        ->and($consultation->status)->toBeInstanceOf(ConsultationStatus::class);
});

// Example enum test
test('user type only accepts valid values', function () {
    expect(UserType::cases())->toHaveCount(3)
        ->and(UserType::Admin->value)->toBe('admin')
        ->and(UserType::Individual->value)->toBe('individual')
        ->and(UserType::Company->value)->toBe('company');
});
```

## Definition of Done

- [ ] All database migrations created and run without errors
- [ ] All model factories functional and generate valid data
- [ ] All Eloquent models have proper relationships and casts
- [ ] All PHP enums created with correct values
- [ ] Development environment runs with `composer run dev`
- [ ] Tests pass for all models, factories, and enums
- [ ] Code formatted with `vendor/bin/pint`
- [ ] No errors on fresh install (`php artisan migrate:fresh`)

## Dependencies

- None (this is the foundation story)

## Risk Assessment

| Risk | Impact | Likelihood | Mitigation |
|------|--------|------------|------------|
| Schema design changes required later | Medium | Low | Follow architecture document closely |
| Migration order issues (FK constraints) | Low | Medium | Create migrations in dependency order |
| Enum value mismatches | Low | Low | Use architecture document as source of truth |

### Error Handling

- **Migration failures:** Run `php artisan migrate:status` to identify failed migrations
- **Foreign key errors:** Ensure referenced tables are created before dependent tables (users before consultations, timelines before timeline_updates)
- **Factory errors:** Ensure factories define all required (non-nullable) fields and use valid enum values
- **Rollback:** Use `php artisan migrate:fresh` to reset in development
