### User Model Helper Methods (Add to User.php)
```php
// app/Models/User.php
use App\Enums\UserType;
use App\Enums\UserStatus;

public function isAdmin(): bool
{
    return $this->user_type === UserType::Admin;
}

public function isClient(): bool
{
    return in_array($this->user_type, [UserType::Individual, UserType::Company]);
}

public function isIndividual(): bool
{
    return $this->user_type === UserType::Individual;
}

public function isCompany(): bool
{
    return $this->user_type === UserType::Company;
}

public function isActive(): bool
{
    return $this->status === UserStatus::Active;
}
```

### Middleware Implementation (from Architecture Section 7.3)
```php
// app/Http/Middleware/EnsureUserIsAdmin.php
class EnsureUserIsAdmin
{
    public function handle(Request $request, Closure $next): Response
    {
        if (!$request->user()?->isAdmin()) {
            abort(403, __('messages.unauthorized'));
        }

        return $next($request);
    }
}

// app/Http/Middleware/EnsureUserIsActive.php
class EnsureUserIsActive
{
    public function handle(Request $request, Closure $next): Response
    {
        if ($request->user()?->status === UserStatus::Deactivated) {
            Auth::logout();
            $request->session()->invalidate();
            $request->session()->regenerateToken();

            return redirect()->route('login')
                ->with('error', __('auth.account_deactivated'));
        }

        return $next($request);
    }
}
```

### Middleware Registration (bootstrap/app.php)
```php
// bootstrap/app.php
->withMiddleware(function (Middleware $middleware) {
    $middleware->web(append: [
        \App\Http\Middleware\SetLocale::class,
    ]);

    $middleware->alias([
        'admin' => \App\Http\Middleware\EnsureUserIsAdmin::class,
        'active' => \App\Http\Middleware\EnsureUserIsActive::class,
    ]);
})
```

### Fortify Configuration
```php
// config/fortify.php
'features' => [
    // Features::registration(), // DISABLED - admin creates accounts
    Features::resetPasswords(),
    Features::emailVerification(),
    Features::updateProfileInformation(),
    Features::updatePasswords(),
    Features::twoFactorAuthentication([
        'confirm' => true,
        'confirmPassword' => true,
    ]),
],
```

### FortifyServiceProvider Setup
```php
// app/Providers/FortifyServiceProvider.php
public function boot(): void
{
    // Custom login view
    Fortify::loginView(fn () => view('livewire.auth.login'));

    // Custom authentication logic (optional - for deactivated check)
    Fortify::authenticateUsing(function (Request $request) {
        $user = User::where('email', $request->email)->first();

        if ($user &&
            Hash::check($request->password, $user->password) &&
            $user->status === UserStatus::Active) {
            return $user;
        }

        return null;
    });
}
```

### Login Redirect Logic
```php
// app/Providers/FortifyServiceProvider.php or custom response
// After successful login, redirect based on role:
if ($user->isAdmin()) {
    return redirect('/admin/dashboard');
}
return redirect('/client/dashboard');
```

### Placeholder Dashboard Routes
```php
// routes/web.php
Route::middleware(['auth', 'active'])->group(function () {
    // Admin routes
    Route::middleware('admin')->prefix('admin')->group(function () {
        Route::view('/dashboard', 'livewire.admin.dashboard-placeholder')
            ->name('admin.dashboard');
    });

    // Client routes
    Route::prefix('client')->group(function () {
        Route::view('/dashboard', 'livewire.client.dashboard-placeholder')
            ->name('client.dashboard');
    });
});
```

### Environment Configuration
```env
SESSION_LIFETIME=120    # 2 hours in minutes
SESSION_EXPIRE_ON_CLOSE=false
```

### Translation Keys (lang/en/auth.php and lang/ar/auth.php)
```php
// lang/en/auth.php
return [
    'failed' => 'These credentials do not match our records.',
    'password' => 'The provided password is incorrect.',
    'throttle' => 'Too many login attempts. Please try again in :seconds seconds.',
    'account_deactivated' => 'Your account has been deactivated. Please contact the administrator.',
];

// lang/ar/auth.php
return [
    'failed' => 'بيانات الاعتماد هذه لا تتطابق مع سجلاتنا.',
    'password' => 'كلمة المرور المقدمة غير صحيحة.',
    'throttle' => 'محاولات تسجيل دخول كثيرة جداً. يرجى المحاولة مرة أخرى بعد :seconds ثانية.',
    'account_deactivated' => 'تم تعطيل حسابك. يرجى الاتصال بالمسؤول.',
];
```

### Edge Case Behavior

**Rate Limiting (5 attempts per minute):**
- Fortify handles this automatically via `RateLimiter`
- After 5 failed attempts, shows throttle message in current locale
- Lockout duration: 60 seconds

**Session Timeout (2 hours inactivity):**
- Configured via `SESSION_LIFETIME=120`
- When session expires, redirect to login page
- Intended URL preserved for redirect after re-authentication

**Deactivated Account Login Attempt:**
- Check in `Fortify::authenticateUsing()` callback
- Reject with `auth.account_deactivated` message
- User never gets authenticated

### Flux UI Components for Login Form
```blade
<flux:input type="email" wire:model="email" label="{{ __('Email') }}" required />
<flux:input type="password" wire:model="password" label="{{ __('Password') }}" required />
<flux:checkbox wire:model="remember" label="{{ __('Remember me') }}" />
<flux:button type="submit" variant="primary">{{ __('Login') }}</flux:button>
```

## Testing

### Test Location
- Feature tests: `tests/Feature/Auth/`
- Unit tests: `tests/Unit/Models/`

### Testing Framework
Pest 4 with Volt testing support

### Feature Tests (tests/Feature/Auth/LoginTest.php)

**Login Flow:**
- [ ] `test_login_page_renders_correctly` - Login page displays
- [ ] `test_user_can_login_with_valid_credentials` - Valid credentials authenticate
- [ ] `test_admin_redirects_to_admin_dashboard` - Admin → `/admin/dashboard`
- [ ] `test_client_redirects_to_client_dashboard` - Client → `/client/dashboard`
- [ ] `test_invalid_credentials_show_error` - Wrong password shows error
- [ ] `test_nonexistent_user_shows_error` - Unknown email shows generic error (no enumeration)
- [ ] `test_deactivated_user_cannot_login` - Deactivated account rejected

**Rate Limiting:**
- [ ] `test_rate_limiting_blocks_after_five_attempts` - 6th attempt blocked
- [ ] `test_rate_limit_resets_after_cooldown` - Can retry after 60 seconds

**Session Management:**
- [ ] `test_logout_clears_session` - Logout destroys session
- [ ] `test_authenticated_user_cannot_access_login_page` - Redirect to dashboard

### Feature Tests (tests/Feature/Auth/AuthorizationTest.php)

**Middleware:**
- [ ] `test_admin_can_access_admin_routes` - Admin passes `admin` middleware
- [ ] `test_client_cannot_access_admin_routes` - Client gets 403
- [ ] `test_unauthenticated_user_redirected_to_login` - Guest redirected
- [ ] `test_deactivated_user_logged_out_on_request` - Active middleware works

### Unit Tests (tests/Unit/Models/UserHelperMethodsTest.php)

**Helper Methods:**
- [ ] `test_isAdmin_returns_true_for_admin_user`
- [ ] `test_isAdmin_returns_false_for_client_user`
- [ ] `test_isClient_returns_true_for_individual_user`
- [ ] `test_isClient_returns_true_for_company_user`
- [ ] `test_isClient_returns_false_for_admin_user`
- [ ] `test_isActive_returns_true_for_active_user`
- [ ] `test_isActive_returns_false_for_deactivated_user`

### Test Patterns
```php
// tests/Feature/Auth/LoginTest.php
use App\Models\User;
use App\Enums\UserType;
use App\Enums\UserStatus;
use Livewire\Volt\Volt;

test('admin redirects to admin dashboard after login', function () {
    $admin = User::factory()->create([
        'user_type' => UserType::Admin,
        'status' => UserStatus::Active,
    ]);

    $response = $this->post('/login', [
        'email' => $admin->email,
        'password' => 'password',
    ]);

    $response->assertRedirect('/admin/dashboard');
    $this->assertAuthenticatedAs($admin);
});

test('deactivated user cannot login', function () {
    $user = User::factory()->create([
        'status' => UserStatus::Deactivated,
    ]);

    $response = $this->post('/login', [
        'email' => $user->email,
        'password' => 'password',
    ]);

    $this->assertGuest();
});

test('client cannot access admin routes', function () {
    $client = User::factory()->create([
        'user_type' => UserType::Individual,
    ]);

    $this->actingAs($client)
        ->get('/admin/dashboard')
        ->assertForbidden();
});
```

## Definition of Done

- [ ] Login page renders correctly in both languages
- [ ] Users can log in with valid credentials
- [ ] Invalid credentials show proper error (bilingual)
- [ ] Deactivated users cannot log in
- [ ] Rate limiting prevents brute force (5 attempts/minute)
- [ ] Session expires after 2 hours inactivity
- [ ] Admin routes protected by `admin` middleware (403 for clients)
- [ ] Failed login attempts logged to `admin_logs`
- [ ] All Feature and Unit tests pass
- [ ] Code formatted with `vendor/bin/pint`

## Dependencies

- **Story 1.1:** Database schema - provides `users` table with `user_type` enum, `status` enum, and `preferred_language` field
- **Story 1.3:** Bilingual infrastructure - provides translation files and locale switching (can be developed in parallel)

## Risk Assessment

| Risk | Impact | Likelihood | Mitigation |
|------|--------|------------|------------|
| Security misconfiguration | High | Low | Use Laravel's built-in security features |
| Rate limiting bypass | Medium | Low | Use Fortify's built-in rate limiter |
| Session hijacking | High | Low | Use secure session configuration |
| Middleware registration issues | Low | Medium | Follow architecture Section 7.4 exactly |

### Rollback Plan
- Restore default Fortify configuration
- Remove custom middleware
- Revert User model changes

**Modified Files:**
- `config/fortify.php` - Disabled registration, enabled all other features
- `app/Models/User.php` - Added `isActive()` method
- `app/Providers/FortifyServiceProvider.php` - Added custom auth, login response, email verify response

- `bootstrap/app.php` - Registered middleware aliases (admin, active) and SetLocale
- `routes/web.php` - Added admin/client dashboard routes with middleware
- `resources/views/livewire/auth/login.blade.php` - Added error message display
- `resources/views/components/layouts/app/sidebar.blade.php` - Fixed dashboard route and user name
- `tests/Feature/Auth/AuthenticationTest.php` - Updated for role-based redirects
- `tests/Feature/Auth/RegistrationTest.php` - Updated for disabled registration
- `tests/Feature/Auth/EmailVerificationTest.php` - Updated for role-based redirects
- `tests/Feature/DashboardTest.php` - Updated for role-based dashboards

### Completion Notes
- All 121 tests pass
- Registration feature disabled per AC 7
- Role-based redirects implemented (admin → /admin/dashboard, client → /client/dashboard)
- Custom middleware for admin authorization and active user checking
- Failed login attempts logged to admin_logs table
- Bilingual support with SetLocale middleware and translation files
- Rate limiting configured (5 attempts per minute via Fortify)
- Session timeout set to 2 hours (SESSION_LIFETIME=120)
- Note: Created migration to make admin_id nullable in admin_logs table for failed login logging

### Future Recommendations (from QA Review)
- **Add `verified` middleware to dashboard routes**: Per `architecture.md` Section 7.5, routes should use `['auth', 'verified', 'active']` middleware. Currently using `['auth', 'active']`. Add `verified` middleware in `routes/web.php:11` when email verification flow is fully implemented and tested in future epics. This ensures only email-verified users can access protected routes.

## QA Results

### Review Date: December 26, 2025

### Reviewed By: Quinn (Test Architect)

### Risk Assessment
**Deep review triggered by:**
- Auth/security files touched (middleware, login, session handling)
- Story has > 5 acceptance criteria (21 ACs)
- Security-critical implementation

### Code Quality Assessment

The implementation demonstrates **high-quality, secure, and well-structured code**:

1. **Middleware Implementation** - Clean, focused, single-responsibility middleware classes:
   - `EnsureUserIsAdmin` - Properly checks admin role and returns 403 with translated message
   - `EnsureUserIsActive` - Correctly logs out deactivated users, invalidates session, regenerates CSRF token
   - `SetLocale` - Appropriately cascades from user preference → session → config default

2. **User Model Helpers** - Well-implemented helper methods:
   - `isAdmin()`, `isClient()`, `isIndividual()`, `isCompany()`, `isActive()` - All correctly use enum comparisons
   - Scopes (`scopeAdmins`, `scopeClients`, `scopeActive`) - Properly implemented for query building

3. **Fortify Integration** - Properly configured:
   - Registration disabled per AC 7
   - Custom `authenticateUsing` callback rejects deactivated users at authentication time
   - Custom `LoginResponse` and `VerifyEmailResponse` handle role-based redirects
   - Rate limiting configured at 5 attempts per minute

4. **Failed Login Logging** - `LogFailedLoginAttempt` listener correctly logs to `admin_logs` with IP address

5. **Bilingual Support** - Complete translation files for `auth.php` and `messages.php` in both `en` and `ar`

### Refactoring Performed
No refactoring performed - code quality is already excellent.

### Compliance Check
- Coding Standards: ✓ All files pass `vendor/bin/pint --dirty --test`
- Project Structure: ✓ Follows Laravel 12 conventions (middleware in `app/Http/Middleware/`, registration in `bootstrap/app.php`)
- Testing Strategy: ✓ Feature tests for flows, Unit tests for model methods
- All ACs Met: ✓ All 21 acceptance criteria covered

### Improvements Checklist
- [x] All implementation complete and tested
- [x] Code formatted with Pint
- [x] Bilingual translations provided
- [x] Rate limiting configured
- [x] Session security configured
- [ ] Consider adding `verified` middleware to dashboard routes (per architecture.md Section 7.5) - low priority, can be added when email verification flow is fully tested in future epics

### Security Review
**PASS** - No security vulnerabilities found:
- ✓ CSRF protection enabled (`@csrf` in forms)
- ✓ Password hashing using bcrypt (Laravel default)
- ✓ Rate limiting prevents brute force attacks (5 attempts/minute)
- ✓ Session regeneration on logout (prevents session fixation)
- ✓ Deactivated users blocked at authentication and via middleware
- ✓ No sensitive data exposure in error messages
- ✓ Generic error message for non-existent users (prevents user enumeration)
- ✓ Admin routes protected with 403 for unauthorized access
- ✓ Failed login attempts logged with IP for audit trail

### Performance Considerations
**PASS** - No performance issues:
- Middleware checks are lightweight (single database field comparisons)
- No N+1 queries in authentication flow
- Session-based authentication (no expensive lookups per request)

### Files Modified During Review
None - no modifications made during review.

### Gate Status
Gate: **PASS** → docs/qa/gates/1.2-authentication-role-system.yml

### Recommended Status
**✓ Ready for Done** - All acceptance criteria met, 121 tests passing, no security issues, code quality excellent.
