+
+### Completion Notes
+- Migration `2026_01_03_165813_add_guest_fields_to_consultations_table.php` created successfully
+- User model uses `full_name` attribute instead of `name` - updated `getClientName()` accordingly
+- Added `scopeGuests()` and `scopeClients()` query scopes as recommended in Technical Notes
+- All 17 new unit tests pass; all 190 consultation-related tests pass
+- Pre-existing memory exhaustion issue in test suite unrelated to these changes

+## QA Results
+
+### Review Date: 2026-01-03
+
+### Reviewed By: Quinn (Test Architect)
+
+### Risk Assessment
+- **Risk Level**: LOW
+- **Rationale**: Foundational data layer change with no auth/payment/security components directly modified
+- **Lines Changed**: ~150 lines across 4 files (below 500-line threshold)
+- **Previous Gate**: N/A (first review)
+
+### Code Quality Assessment
+
+**Overall: EXCELLENT**
+
+The implementation demonstrates strong adherence to Laravel and project conventions:
+
+1. **Model Updates** (`app/Models/Consultation.php`):
+   - Correct use of `$fillable` for mass assignment protection
+   - Proper `booted()` hook for domain validation (ensures guest bookings have required fields)
+   - Clean helper methods (`isGuest()`, `getClientName()`, `getClientEmail()`, `getClientPhone()`)
+   - Query scopes (`scopeGuests()`, `scopeClients()`) added as recommended in Technical Notes
+   - Correctly uses `user->full_name` matching existing User model attribute
+
+2. **Migration** (`database/migrations/2026_01_03_...`):
+   - Proper use of `->nullable()->change()` for making `user_id` nullable
+   - Correct column order using `->after()` for logical grouping
+   - Index added on `guest_email` for lookup performance
+   - Reversible migration with appropriate down() method
+   - Clear comment noting data loss caveat for NOT NULL restoration
+
+3. **Factory** (`database/factories/ConsultationFactory.php`):
+   - `guest()` state properly nullifies `user_id` and sets guest fields
+   - Uses `fake()->unique()->safeEmail()` to prevent conflicts in tests
+
+### Requirements Traceability
+
+| AC | Description | Test Coverage | Status |
+|----|-------------|---------------|--------|
+| 1 | `user_id` nullable | Schema verified via migration + `consultation can be created for client` | ✓ |
+| 2 | `guest_name` column added | `getClientName returns guest name for guest consultation` | ✓ |
+| 3 | `guest_email` column added | `getClientEmail returns guest email for guest consultation` | ✓ |
+| 4 | `guest_phone` column added | `getClientPhone returns guest phone for guest consultation` | ✓ |
+| 5 | Index on `guest_email` | Schema verification (index exists) | ✓ |
+| 6 | Migration reversible | `down()` method drops columns/index properly | ✓ |
+| 7 | Existing consultations unaffected | `existing consultations with user are not affected` | ✓ |
+| 8 | New fillable fields | `consultation can be created as guest` | ✓ |
+| 9 | `isGuest()` helper | `consultation can be created as guest`, `consultation can be created for client` | ✓ |
+| 10 | `getClientName()` helper | Tests for both guest and client variants | ✓ |
+| 11 | `getClientEmail()` helper | Tests for both guest and client variants | ✓ |
+| 12 | `getClientPhone()` helper | Tests for both guest and client variants | ✓ |
+| 13 | Validation (user_id OR guest fields) | `guest consultation throws exception without required fields` | ✓ |
+| 14 | Factory `guest()` state | `consultation can be created as guest` | ✓ |
+| 15 | `scopeGuests()` | `guests scope returns only guest consultations` | ✓ |
+| 16 | `scopeClients()` | `clients scope returns only client consultations` | ✓ |
+
+**Coverage**: 16/16 acceptance criteria mapped to tests (100%)
+
+### Test Architecture Assessment
+
+- **Test Count**: 17 new tests with 27 assertions
+- **Test Level**: Appropriate unit tests for model behavior
+- **Test Quality**: Clean, focused tests following Given-When-Then pattern
+- **Edge Cases**:
+  - ✓ Guest without required fields (throws exception)
+  - ✓ Mixed guest/client scopes
+  - ✓ Explicit field values (e.g., `guest_name` = 'John Doe')
+- **Execution Time**: 0.22s (excellent)
+
+### Refactoring Performed
+
+None required. Implementation is clean and follows project standards.
+
+### Compliance Check
+
+- Coding Standards: ✓ Pint passes, naming conventions followed
+- Project Structure: ✓ Files in correct locations
+- Testing Strategy: ✓ Unit tests for model layer
+- All ACs Met: ✓ All 16 acceptance criteria implemented and tested
+
+### Improvements Checklist
+
+- [x] All acceptance criteria implemented
+- [x] All required tests passing (17/17)
+- [x] Migration is reversible
+- [x] Domain validation in model boot
+- [x] Query scopes added per Technical Notes
+- [ ] *Future consideration*: Add integration test for cascade delete behavior (guest consultations should survive user deletions since they have no user_id)
+
+### Security Review
+
+**Status: PASS**
+
+- No sensitive data exposed
+- Guest email indexed but not unique (intentional for 1-per-day business rule to be enforced at application layer)
+- Model validation prevents malformed guest consultations (requires all three guest fields)
+- Foreign key cascade behavior preserved for registered user consultations
+
+### Performance Considerations
+
+**Status: PASS**
+
+- Index on `guest_email` added for O(log n) lookups
+- No N+1 query risks introduced
+- Helper methods are simple attribute access, no database calls
+
+### Files Modified During Review
+
+None. No refactoring required.
+
+### Gate Status
+
+**Gate: PASS** → `docs/qa/gates/11.1-database-schema-model-updates.yml`
+
+### Recommended Status
+
+**✓ Ready for Done**
+
+All acceptance criteria met, comprehensive test coverage (17 tests/27 assertions), clean implementation following project patterns. No blocking issues identified.
