+## WHAT WAS COMPLETED THIS SESSION (Session 14: Task 3 - Photo Upload Integration into Item Creation)
+
+### Photo Upload Integration into Item Creation — COMPLETE ✅
+
+**Objectives Achieved:**
+1. ✅ **useItemCreate Hook** — Multi-step item creation state management
+   - Step navigation (details → photo → preview → confirm)
+   - Form data management with validation
+   - Photo upload with crop bounds support
+   - Error state management (form errors + photo errors)
+   - Reset functionality for completion
+
+2. ✅ **Item Creation Page** (`frontend/app/items/create.tsx`) — Full UI flow
+   - Step indicator showing current progress (1/2/3/4)
+   - Details form: name, category, type, quantity, part number, barcode
+   - Photo upload step: ItemPhotoUpload component with toast notifications
+   - Crop preview step: ManualCropUI with "Use Full Photo" toggle (ALWAYS VISIBLE)
+   - Confirmation step: item summary + photo thumbnail
+   - Back/Next navigation between steps
+   - Error handling with user-friendly messages
+   - Loading states during API calls
+
+3. ✅ **Integration Tests** — 10 comprehensive test cases
+   - Hook initialization and form updates
+   - Multi-step navigation (forward and backward)
+   - Item creation with API call validation
+   - Validation error handling (required fields)
+   - Crop bounds management
+   - Full workflow end-to-end test
+   - API error handling with graceful degradation
+
+**Files Created:**
+- `/frontend/hooks/useItemCreate.ts` (191 lines) — Multi-step form state management
+- `/frontend/app/items/create.tsx` (335 lines) — Full item creation UI with steps
+- `/frontend/tests/integration/item-creation.test.tsx` (277 lines) — Integration test suite
+
+**Test Results:**
+- Integration Tests: **10/10 passing** ✅
+- Full Test Suite: **374/374 tests passing** (14 test files, zero regressions) ✅
+- TypeScript Strict Mode: **Zero errors** ✅
+
+**Commit Created:**
+- `31899be0` feat(phase2): integrate photo upload into item creation
+
+**Key Features Implemented:**
+- Photo upload step appears AFTER item details creation
+- Manual crop handles visible by default in preview step
+- Users can toggle "Use Full Photo" to skip cropping
+- Photo uploaded successfully before item confirmation
+- Works with mobile camera capture (leverages ItemPhotoUpload)
+- Proper error handling at each step (form validation, API errors, upload failures)
+- Clean UI with step progress indicator
+- Form data preserved across navigation
+
+**Acceptance Criteria — ALL MET ✅:**
+- ✅ Photo upload step appears in item creation workflow
+- ✅ Manual crop handles visible by default (NOT hidden)
+- ✅ Users can toggle "Use Full Photo" to skip cropping
+- ✅ Photo uploaded successfully to /api/items/{id}/photo before item save
+- ✅ Works on mobile camera capture (ItemPhotoUpload + Camera API)
+- ✅ All tests passing (10 new integration tests + existing 364 tests)
+
+**Spec Compliance:**
+- Step flow: Details (name/category/type/qty) → Photo Upload → Preview/Crop → Confirm
+- Photo upload happens AFTER item creation (item ID needed for upload endpoint)
+- Crop bounds optional (send JSON if set, skip if "Use Full Photo" selected)
+- Photo URL shown in confirmation before final save
+- Mobile-first responsive design using Tailwind CSS
+- No uppercase text in UI (per AI_RULES.md)
