Phase 6 UAT completed:
- Auth: ✅ PASS (admin/admin working)
- AI item creation: ✅ PASS (scan/photo working)
- Search: ❌ FAIL (no button on main page, Ctrl+K not wired)
- Export: ❌ FAIL (404 endpoint mismatch)
- Admin dashboard: ✅ PARTIAL (accessible but export broken)

+
+## Critical Issues
+
+### Issue 1: Missing Search UI on Main Page
+**Severity:** HIGH  
+**Location:** Main page (not inventory page)  
+**Problem:**
+- No visible search button on main page
+- SearchModal component exists but not rendered
+- Ctrl+K keyboard shortcut not implemented
+- Users cannot search inventory items
+
+**Root Cause:** 
+- SearchModal component imported but conditional render missing
+- Keyboard listener not wired to main page component
+
+**Fix Plan:**
+1. Add search button to main page header/navbar
+2. Render SearchModal on main page
+3. Wire Ctrl+K listener to open/close modal
+4. Test search across all item fields
+
+**Effort:** 1-2 hours
+
+---
+
+### Issue 2: Export Endpoint Mismatch
+**Severity:** HIGH  
+**Location:** Admin → Export feature  
+**Problem:**
+- Frontend calls: `/admin/db/export` (GET)
+- Backend provides: `/admin/inventory-snapshot` (POST), `/admin/audit-trail` (POST)
+- All export attempts return 404
+
+**Root Cause:**
+- Frontend and backend endpoint paths don't match
+- Method types mismatch (GET vs POST)
+
+**Fix Plan (Choose One):**
+
+**Option A: Create `/admin/db/export` endpoint (Recommended)**
+- Implement GET `/admin/db/export` in backend
+- Combine snapshot + audit trail logic
+- Support format parameter: ?format=csv|json|excel
+- Return appropriate blob/file type
+
+**Option B: Update frontend to call existing endpoints**
+- Change frontend calls to `/admin/inventory-snapshot` and `/admin/audit-trail`
+- Convert POST to GET or update frontend to use POST
+- Handle multiple endpoint calls for combined export
+
+**Recommendation:** Option A (simpler for user, cleaner API)  
+**Effort:** 1-2 hours
+
+---
+
+## Verified Working Features
+
+✅ **Deployment:**
+- Standalone deployment with Python launcher working
+- Docker containerization functional
+- Self-signed SSL/TLS certificates working
+- HTTP and HTTPS access both available
+
+✅ **Authentication:**
+- Local auth (admin/admin) fully functional
+- JWT token generation and validation working
+- Auth guards protecting API endpoints
+
+✅ **Core Inventory:**
+- AI Smart Discovery (scan/photo) adding items correctly
+- Items persisted to SQLite database
+- Admin dashboard accessible
+
+---
+
+## Next Steps
+
+1. **Fix Issue 1 (Search):**
+   - Add search button to main page
+   - Wire SearchModal + Ctrl+K listener
+   - Test search functionality
+
+2. **Fix Issue 2 (Export):**
+   - Implement `/admin/db/export` endpoint in backend
+   - Support CSV, JSON, Excel formats
+   - Test all export types
+
+3. **Re-test & Verify:**
+   - Run full UAT again after fixes
+   - Confirm both issues resolved
+
