## 🔄 State Management & Data Flow

### Context Structure

```javascript
const WizardContext = {
  // Navigation
  currentStep: 0,
  totalSteps: 3,
  selectedItemType: null, // 'inventory', 'supplier', etc.

  // Data
  formData: {}, // Step-specific data
  validationErrors: {},

  // Actions
  goToStep: (step) => {},
  nextStep: () => {},
  prevStep: () => {},
  setItemType: (type) => {},
  updateFormData: (data) => {},
  submitWizard: async () => {},

  // Draft saving
  saveDraft: () => {}, // Auto-save to localStorage
  loadDraft: () => {},
  clearDraft: () => {},

  // Utilities
  isStepValid: (step) => boolean,
  canProceed: () => boolean,
}
```

### API Integration Pattern

```javascript
// Use existing React Query hooks
const { mutate: createItem, isLoading } = useCreateItem(itemType);

const handleSubmit = async (formData) => {
  try {
    await createItem(formData);
    showSuccessMessage();
    onClose();
    // Suggest next action
  } catch (error) {
    showErrorMessage(error);
  }
};
```

## 🎯 Progressive Disclosure Strategy

### Level 1: Item Type Selection (Cognitive Load: Low)
**Show:** 9 visual cards with clear icons and descriptions
**Hide:** All form complexity

### Level 2: Wizard Steps (Cognitive Load: Medium)
**Show:** Only current step, progress indicator, clear next action
**Hide:** Other steps, advanced options (collapsible)

### Level 3: Within Step (Cognitive Load: Low per section)
**Show:** Required fields first, grouped logically
**Hide:** Optional fields in "Advanced Options" accordion

### Level 4: Help & Context (Available on demand)
**Show:** ? icons for field-specific help tooltips
**Hide:** Lengthy explanations unless requested

---

## 📱 Mobile-Specific Optimizations

### Navigation
- **Bottom sheet on mobile** (easier thumb reach)
- **Swipe gestures** to go back/forward between steps
- **Sticky footer buttons** always visible

### Input Methods
- **Native date/time pickers** on mobile
- **Autocomplete** for product/customer selection
- **Camera integration** for barcode scanning (future enhancement)

### Performance
- **Lazy load** individual wizards (code splitting)
- **Debounced validation** (don't validate on every keystroke)
- **Optimistic UI updates** for better perceived performance

### Offline Support (Future)
- Save drafts to localStorage
- Queue submissions when offline
- Sync when connection restored

---

## ✅ Validation Strategy

### Real-time Validation
- Required field indicators (asterisk)
- Field-level validation on blur
- Clear error messages below fields
- Success indicators (green checkmark) when valid

### Step-level Validation
- "Next" button disabled until step is valid
- Summary of errors at top if user tries to proceed
- Auto-focus first invalid field

### Relationship Validation
- Check if recipe ingredients exist in inventory
- Warn if adding duplicate items
- Suggest existing items that match (fuzzy search)

---
