``` ### Calendar Integration Note The `availability-calendar` component (from Story 3.3) uses the pattern `$parent.selectSlot()` to communicate slot selection back to the parent component. The parent booking component needs to have the `selectSlot(string $date, string $time)` method to receive this. ### 1-Per-Day Validation Rule ```php where('user_id', auth()->id()) ->whereDate('booking_date', $value) ->whereIn('status', [ConsultationStatus::Pending, ConsultationStatus::Approved]) ->exists(); if ($exists) { $fail(__('booking.already_booked_this_day')); } } } ``` ### Testing #### Test File Location `tests/Feature/Client/BookingSubmissionTest.php` #### Required Test Scenarios ```php create([ 'day_of_week' => 1, 'start_time' => '09:00', 'end_time' => '17:00', 'is_active' => true, ]);

Please select another.', 'slot_taken' => 'This slot was just booked. Please select another time.', ``` Add corresponding Arabic translations to `lang/ar/booking.php`. ## Definition of Done - [ ] Volt component created at correct path - [ ] Can select date from calendar - [ ] Can select time slot - [ ] Problem summary required (min 20 chars) - [ ] 1-per-day limit enforced - [ ] Race condition prevented with DB locking - [ ] Confirmation step before submission - [ ] Booking created with "pending" status - [ ] Client email sent - [ ] Admin email sent - [ ] Audit log entry created - [ ] Bilingual support complete - [ ] All tests passing - [ ] Code formatted with Pint ## Dependencies - **Story 3.3:** Availability calendar (COMPLETED) - Provides `AvailabilityService` for slot availability checking - Provides `availability-calendar` Livewire component - **Epic 2:** User authentication (COMPLETED) - Client must be logged in to submit bookings - **Epic 8:** Email notifications (partial - mail classes needed) ## Risk Assessment | Risk | Impact | Mitigation | |------|--------|------------| | Double-booking race condition | High | DB transaction with `lockForUpdate()` | | Email delivery failure | Medium | Use queue with retries | | Timezone confusion | Low | Use `whereDate()` for date comparison | ## Estimation **Complexity:** Medium-High **Estimated Effort:** 4-5 hours --- ## Dev Agent Record ### Agent Model Used Claude Opus 4.5 ### File List | File | Action | Purpose | |------|--------|---------| | `resources/views/livewire/client/consultations/book.blade.php` | Created | Main booking form Volt component | | `resources/views/livewire/client/consultations/index.blade.php` | Created | Client consultations list (redirect target) | | `app/Mail/BookingSubmittedMail.php` | Created | Client confirmation email | | `app/Mail/NewBookingRequestMail.php` | Created | Admin notification email | | `resources/views/emails/booking-submitted.blade.php` | Created | Client email template | | `resources/views/emails/new-booking-request.blade.php` | Created | Admin email template | | `tests/Feature/Client/BookingSubmissionTest.php` | Created | Feature tests (18 tests) | | `routes/web.php` | Modified | Added client consultations routes | | `lang/en/booking.php` | Modified | Added booking form translation keys | | `lang/ar/booking.php` | Modified | Added Arabic booking translations | | `lang/en/common.php` | Modified | Added common UI translation keys | | `lang/ar/common.php` | Modified | Added Arabic common translations | | `lang/en/emails.php` | Modified | Added email translation keys | | `lang/ar/emails.php` | Modified | Added Arabic email translations | | `lang/en/enums.php` | Created | ConsultationStatus labels | | `lang/ar/enums.php` | Created | Arabic ConsultationStatus labels | | `app/Enums/ConsultationStatus.php` | Modified | Added label() method | ### Debug Log References None -

Race condition prevention implemented with DB transactions and lockForUpdate() - Emails queued directly via Mail facade (no separate job class needed) - 1-per-day validation implemented inline in component (no separate Rule class needed) ## Change Log | Date | Version | Description | Author | |------|---------|-------------|--------| | 2025-12-26 | 1.0 | Initial draft | - | | 2025-12-26 | 1.1 | Fixed column names (booking_date/booking_time), removed hallucinated duration field, fixed AdminLog column, removed invalid cross-story task, added Tasks/Subtasks section, aligned with source tree architecture | QA Validation | | 2025-12-26 | 1.2 | Implementation complete - all tasks done, tests passing, ready for review | Dev Agent | ## QA Results ### Review Date: 2025-12-26 ### Reviewed By: Quinn (Test Architect) ### Risk Assessment **Review Depth: Standard** - No high-risk triggers detected (no auth/payment files modified beyond expected booking flow, reasonable test coverage, appropriate line count, first review). ### Code Quality Assessment **Overall: Excellent** - The implementation is clean, well-structured, and follows Laravel/Livewire best practices. **Strengths:** - Clean Volt component architecture with proper separation of concerns - Excellent race condition prevention using `DB::transaction()` with `lockForUpdate()` - Double validation strategy (pre-confirmation + in-transaction) provides defense in depth - Proper use of Flux UI components throughout - Bilingual support complete with proper RTL handling in email templates - Good error handling with user-friendly messages **Code Patterns:** - `book.blade.php:76-134` - Transaction with pessimistic locking correctly prevents race conditions - `book.blade.php:48-52,90-95` - 1-per-day validation checked both pre and in-transaction - Mail classes properly use `Queueable` trait and respect user's `preferred_language` ### Requirements Traceability | AC | Requirement | Test Coverage | Status | |----|-------------|---------------|--------| | AC1 | Client must be logged in | `guest cannot access booking form`, `authenticated client can access booking form` | ✓ | | AC2 | Select date from availability calendar | Integration via `availability-calendar` component | ✓ | | AC3 | Select available time slot | `authenticated client can submit booking request` | ✓ | | AC4 | Problem summary field (required, textarea, min 20 chars) | `problem summary is required`, `must be at least 20 characters`, `cannot exceed 2000 characters` | ✓ | | AC5 | Confirmation before submission | `confirmation step displays before final submission` | ✓ | | AC6 | No more than 1 booking per day | `client cannot book more than once per day`, `client can book on different day` | ✓ | | AC7 | Selected slot is still available | `client cannot book unavailable slot` | ✓ | | AC8 | Problem summary not empty | `problem summary is required` | ✓ | | AC9 | Clear error messages | Error messages verified in validation tests | ✓ | | AC10 | Booking enters "pending" status | `booking is created with pending status` | ✓ | | AC11 | Client sees confirmation | `success message shown after submission` | ✓ | | AC12 | Admin receives email | `emails are sent to client and admin after submission` | ✓ | | AC13 | Client receives email | `emails are sent to client and admin after submission` | ✓ | | AC14 | Redirect to consultations list | `authenticated client can submit booking request` -

tests cover happy path, validation, business rules, race conditions, and side effects **Coverage Analysis:** - ✓ Happy path submission flow - ✓ Authentication guard - ✓ All validation rules (required, min, max) - ✓ Business rules (1-per-day, slot availability) - ✓ Race condition scenarios (slot taken, user double-book) - ✓ UI flow states (confirmation, back navigation, clear selection) - ✓ Side effects (emails queued, audit log created) **Test Design Quality:** - Proper use of `Mail::fake()` for email assertions - Good isolation with `beforeEach` for working hours setup - Race condition tests simulate real concurrent booking scenarios - Tests verify both state changes and database records ### Compliance Check - Coding Standards: ✓ Code formatted with Pint - Project Structure: ✓ Files in correct locations per architecture - Testing Strategy: ✓ Feature tests with Pest/Volt - All ACs Met: ✓ 22/22 acceptance criteria validated ### Refactoring Performed No refactoring performed - implementation is clean and follows best practices. ### Improvements Checklist - [x] Race condition prevention with DB locking - [x] Double validation (pre + in-transaction) - [x] Email queuing for async delivery - [x] Proper loading states in UI - [x] Full bilingual support - [x] Audit logging for client actions - [ ] Consider adding a test for admin-only notification when no admin exists (edge case - currently silently skips) - [ ] Consider extracting the 1-per-day check to a query scope on Consultation model for reuse ### Security Review **Status: PASS** - ✓ Authentication required via route middleware (`auth`, `active`) - ✓ Authorization implicit (client can only book for themselves via `auth()->id()`) - ✓ Input validation with Laravel validator - ✓ SQL injection prevented via Eloquent ORM - ✓ XSS prevented via Blade escaping - ✓ CSRF protection via Livewire - ✓ Race condition prevention via pessimistic locking - ✓ Problem summary has max length (2000 chars) preventing payload attacks ### Performance Considerations **Status: PASS** - ✓ Emails queued (not blocking request) - ✓ Database queries are indexed (user_id, booking_date, status) - ✓ No N+1 query issues in the booking flow - ✓ Reasonable transaction scope (creates one consultation, logs one entry) ### Files Modified During Review None - no modifications needed. ### Gate Status Gate: **PASS** → docs/qa/gates/3.4-booking-request-submission.yml ### Recommended Status **✓ Ready for Done** - All acceptance criteria met, comprehensive test coverage, no blocking issues.
