## **2. Completely New WebSocket Integration** ✅ **NEW**

### **itemStore.ts** - **Shopping Collaboration Real-Time System**
- ✅ **Full event coverage**: `item:created`, `item:updated`, `item:deleted`, `item:claimed`, `item:unclaimed`
- ✅ **Collaborative notifications**: Smart alerts for shopping list activity by others
- ✅ **Claim/unclaim awareness**: Real-time shopping coordination with claim status updates
- ✅ **Optimistic updates**: Immediate local updates with WebSocket event broadcasting

- ✅ **Context preservation**: Updates maintain expense data while refreshing list information

## **3. Intelligent Notification System** ✅ **NEW**

### **Smart Notification Logic**
- ✅ **Self-exclusion**: No notifications for actions you initiated (prevents spam)
- ✅ **Relevance filtering**: Only shows notifications that matter to the current user
- ✅ **Contextual messaging**: Specific, actionable notification text with entity names
- ✅ **Duration tuning**: Different timeouts based on event importance (3-5 seconds)
- ✅ **Type categorization**: Success, info, warning types for different event classes

### **Notification Examples**
- 🎯 **Task assignments**: "You have been assigned 'Take out the trash'"
- 🎉 **Task completions**: "'Wash dishes' was completed!" (when others complete)
- 👥 **Member activity**: "John joined Kitchen Household!" / "Jane left Kitchen Household"
- 🛒 **Shopping coordination**: "'Milk' was claimed for shopping" / "'Bread' is available again"
- 💰 **List activity**: "'Groceries' was added to the shopping list" (throttled, short duration)
