## Technical Notes

### Mailable Class
```php
<?php

namespace App\Mail;

use App\Models\User;
use Illuminate\Bus\Queueable;
use Illuminate\Mail\Mailable;
use Illuminate\Mail\Mailables\Content;
use Illuminate\Mail\Mailables\Envelope;
use Illuminate\Queue\SerializesModels;

class WelcomeEmail extends Mailable
{
    use Queueable, SerializesModels;

    public function __construct(
        public User $user,
        public string $password
    ) {}

    public function envelope(): Envelope
    {
        $locale = $this->user->preferred_language ?? 'ar';

        return new Envelope(
            subject: $locale === 'ar'
                ? 'مرحباً بك في مكتب ليبرا للمحاماة'
                : 'Welcome to Libra Law Firm',
        );
    }

    public function content(): Content
    {
        $locale = $this->user->preferred_language ?? 'ar';

        return new Content(
            markdown: "emails.welcome.{$locale}",
            with: [
                'user' => $this->user,
                'password' => $this->password,
                'loginUrl' => route('login'),
            ],
        );
    }
}
```

### Trigger on User Creation
```php
// In User creation flow (Story 2.1/2.2)
public function create(): void
{
    $validated = $this->validate();
    $plainPassword = $this->password;

    $user = User::create([
        ...$validated,
        'password' => Hash::make($this->password),
    ]);

    // Send welcome email with plain password
    Mail::to($user)->queue(new WelcomeEmail($user, $plainPassword));

    session()->flash('success', __('messages.user_created'));
}
```

### Email Theme Customization
```php
// In AppServiceProvider boot()
use Illuminate\Support\Facades\View;

View::composer('vendor.mail.*', function ($view) {
    $view->with('logoUrl', asset('images/logo.png'));
    $view->with('primaryColor', '#0A1F44');
    $view->with('accentColor', '#D4AF37');
});
```

### Testing
```php
use App\Mail\WelcomeEmail;
use Illuminate\Support\Facades\Mail;

it('sends welcome email on user creation', function () {
    Mail::fake();

    // Create user through admin flow
    // ...

    Mail::assertQueued(WelcomeEmail::class, function ($mail) use ($user) {
        return $mail->user->id === $user->id;
    });
});

it('sends email in user preferred language', function () {
    Mail::fake();

    $user = User::factory()->create(['preferred_language' => 'ar']);

    Mail::to($user)->send(new WelcomeEmail($user, 'password123'));

    Mail::assertSent(WelcomeEmail::class, function ($mail) {
        return str_contains($mail->envelope()->subject, 'مرحباً');
    });
});

it('queues welcome email instead of sending synchronously', function () {
    Mail::fake();

    $user = User::factory()->create();

    Mail::to($user)->queue(new WelcomeEmail($user, 'password123'));

    Mail::assertQueued(WelcomeEmail::class);
    Mail::assertNothingSent(); // Confirms it was queued, not sent sync
});

it('does not send email for admin accounts', function () {
    Mail::fake();

    // Admin creation flow should NOT trigger welcome email
    $admin = User::factory()->admin()->create();

    Mail::assertNothingQueued();
});

it('generates plain text version of email', function () {
    $user = User::factory()->create(['preferred_language' => 'en']);
    $mailable = new WelcomeEmail($user, 'password123');

    // Verify mailable can render (catches template errors)
    expect($mailable->render())->toBeString();
});
```

## Definition of Done

- [ ] Welcome email sent on user creation
- [ ] Email contains all required information
- [ ] Login credentials included
- [ ] Branding matches design guidelines
- [ ] Arabic email for Arabic preference
- [ ] English email for English preference
- [ ] Plain text fallback works
- [ ] Email queued (not blocking)
- [ ] No email sent for admin accounts
- [ ] Failed emails logged (non-blocking to user creation)
- [ ] Tests verify email sending
- [ ] Code formatted with Pint

## Dependencies

- **Story 2.1:** Individual client creation
- **Story 2.2:** Company client creation
- **Epic 8:** Full email infrastructure (shared base template)

## Risk Assessment

- **Primary Risk:** Email delivery failures
- **Mitigation:** Queue with retry, logging, admin notification on failure
- **Rollback:** Manual credential sharing if email fails

## Estimation

**Complexity:** Medium
**Estimated Effort:** 3-4 hours

## Dev Agent Record

### Status
Ready for Review

### Agent Model Used
Claude Opus 4.5

### File List
| File | Action |
|------|--------|
| `app/Notifications/WelcomeAccountNotification.php` | Created |
| `resources/views/emails/welcome.blade.php` | Created |
| `lang/en/emails.php` | Modified |
| `lang/ar/emails.php` | Modified |
| `resources/views/livewire/admin/clients/individual/create.blade.php` | Modified |
| `resources/views/livewire/admin/clients/company/create.blade.php` | Modified |
| `tests/Feature/Admin/WelcomeEmailTest.php` | Created |
| `tests/Feature/Admin/IndividualClientTest.php` | Modified |
| `tests/Feature/Admin/CompanyClientTest.php` | Modified |

### Change Log
- Created `WelcomeAccountNotification` class implementing `ShouldQueue` for async email delivery
- Created bilingual email template (`welcome.blade.php`) with RTL support for Arabic
- Added 13 translation keys in both Arabic and English for welcome email content
- Integrated notification dispatch into individual client creation flow
- Integrated notification dispatch into company client creation flow
- Created comprehensive test suite with 13 tests covering:
  - Email queuing for both client types
  - Password inclusion in notification
  - Language preference handling (Arabic/English)
  - Correct data passing to view
  - Queue interface implementation
  - Admin exclusion from welcome emails
  - Non-blocking user creation
- Updated existing client tests to use `Notification::fake()` to prevent email rendering during unrelated tests

### Completion Notes
- Used Laravel Notification pattern (matching existing `AccountReactivatedNotification`, `PasswordResetByAdminNotification`) instead of Mailable pattern suggested in story, for consistency with existing codebase
- Email template uses single blade file with locale-based content switching (matching existing email patterns) rather than separate locale files
- Email branding relies on Laravel's default mail theme; custom branding with Libra colors (#0A1F44, #D4AF37) should be configured in Epic 8 when full email infrastructure is implemented
- Sender configuration (MAIL_FROM_ADDRESS, MAIL_FROM_NAME) should be set in `.env` as noted in story requirements
- All 310 tests pass, code formatted with Pint

### Debug Log References
None - no blocking issues encountered

## QA Results

### Review Date: 2025-12-26

### Reviewed By: Quinn (Test Architect)

### Risk Assessment
- **Risk Level**: Standard (no auth/payment files modified, tests present, diff reasonable)
- **Auto-escalation triggers**: None detected

### Code Quality Assessment
The implementation is **well-executed** and follows established Laravel patterns consistently:

1. **Notification Pattern**: Used `WelcomeAccountNotification` extending Laravel's Notification class with `ShouldQueue` interface - matches existing patterns (`AccountReactivatedNotification`, `PasswordResetByAdminNotification`)
2. **Email Template**: Single blade file with locale-based content switching using `@if($locale === 'ar')` - consistent with project approach
3. **Translation Keys**: 13 new keys added to both `lang/ar/emails.php` and `lang/en/emails.php` following existing conventions
4. **Integration**: Clean integration into both individual and company client creation flows via `$user->notify()`

### Requirements Traceability

| AC# | Acceptance Criteria | Test Coverage | Status |
|-----|---------------------|---------------|--------|
| 1 | Email sent automatically on account creation | `welcome email is queued when creating individual client`, `welcome email is queued when creating company client` | ✓ |
| 2 | Works for both individual and company accounts | Tests exist for both flows | ✓ |
| 3 | Queued for performance (async sending) | `welcome notification implements should queue interface`, `welcome notification uses queueable trait` | ✓ |
| 4 | No email sent for admin accounts | `no welcome email is sent when admin creates another admin via factory` | ✓ |
| 5 | Personalized greeting (Individual/Company) | `welcome email passes correct data to view`, `welcome email passes company name for company clients` | ✓ |
| 6 | Login credentials included | `welcome email contains correct password for individual client`, `welcome email contains correct password for company client` | ✓ |
| 7 | Arabic email for Arabic preference | `welcome email uses arabic subject for arabic preference` | ✓ |
| 8 | English email for English preference | `welcome email uses english subject for english preference` | ✓ |
| 9 | Default to Arabic | `welcome email defaults to arabic when notification receives user without language` | ✓ |
| 10 | User creation succeeds if email fails | `user creation succeeds even if notification would fail` | ✓ |

### Refactoring Performed
None required - implementation quality is high and follows existing patterns.

### Compliance Check

- Coding Standards: ✓ Code formatted with Pint
- Project Structure: ✓ Notification in `app/Notifications/`, template in `resources/views/emails/`
- Testing Strategy: ✓ 13 comprehensive tests covering all ACs
- All ACs Met: ✓ All 10 acceptance criteria verified with tests

### Improvements Checklist

All required items are complete. Future considerations (non-blocking):

- [ ] **Future (Epic 8)**: Add Libra branding colors (#0A1F44, #D4AF37) and logo when full email infrastructure is implemented
- [ ] **Future**: Configure `MAIL_FROM_ADDRESS=no-reply@libra.ps` and `MAIL_FROM_NAME="Libra Law Firm"` in production `.env`
- [ ] **Future**: Add Reply-To header for firm contact email

### Security Review

- ✓ Password transmitted via queued notification (not logged in plain text)
- ✓ No password stored in notification's `toArray()` method (prevents database storage)
- ✓ Email sent only to the user being created (no injection risk)
- **Note**: Password is intentionally visible in email per AC requirements - this is by design for initial account setup

### Performance Considerations

- ✓ Uses `ShouldQueue` interface for async processing
- ✓ Email queued, not blocking user creation flow
- ✓ Laravel's default retry mechanism (3 attempts) applies

### Files Modified During Review
None - no changes required.

### Gate Status

Gate: **PASS** → docs/qa/gates/2.5-account-creation-email-notification.yml

### Recommended Status

✓ **Ready for Done** - All acceptance criteria met, 13 tests passing, code follows established patterns, no blocking issues identified.
