+# Market Module Recursion Issue - Technical Analysis Report
+
+## Executive Summary
+
+A critical recursion issue was discovered in the market module that caused "Maximum recursive updates exceeded" errors, leading to page crashes in production. The issue was traced to multiple overlapping causes in the Vue 3 reactive system, particularly around event processing, component initialization, and search result handling.
+
+## Problem Description
+
+### Initial Symptoms
+- **Error Message**: `Maximum recursive updates exceeded in component <MarketPage>`
+- **Environment**: Both development (`npm run dev`) and production
+- **Impact**: Complete page crash in production, infinite console logging in development
+- **Trigger**: Opening the `/market` route
+
+### Observable Behavior
+```
+🛒 Loading market data for: { identifier: "default", pubkey: "..." }
+🛒 Found 0 market events
+🛒 Loading stalls...
+🛒 Found 3 stall events for 1 merchants
+🛒 Loading products...
+🛒 Found 6 product events for 1 merchants
+[Repeated 4+ times simultaneously]
+```
+
+## Root Cause Analysis
+
+### Primary Causes
+
+#### 1. Multiple useMarket() Composable Instances
+**Location**: `src/modules/market/composables/useMarket.ts`
+
+The `useMarket()` composable contained an `onMounted()` hook that was being called from multiple places:
+- `MarketPage.vue` component
+- `useMarketPreloader` composable
+
+```typescript
+// PROBLEMATIC CODE (removed)
+onMounted(() => {
+  if (needsToLoadMarket.value) {
+    loadMarket()
+  } else if (marketPreloader.isPreloaded.value) {
+    unsubscribe = market.subscribeToMarketUpdates()
+  }
+})
+```
+
+**Issue**: Each instance created separate initialization cycles, leading to:
+- Multiple simultaneous market loading operations
+- Overlapping Nostr event subscriptions
+- Race conditions in state updates
+
+#### 2. Nostr Event Processing Loop
+**Location**: `src/modules/market/composables/useMarket.ts:428-451`
+
+Events were being processed multiple times due to lack of deduplication:
+
+```typescript
+// ORIGINAL PROBLEMATIC CODE
+const handleMarketEvent = (event: any) => {
+  // No deduplication - same events processed repeatedly
+  switch (event.kind) {
+    case MARKET_EVENT_KINDS.PRODUCT:
+      handleProductEvent(event) // This triggered store updates
+      break
+    // ...
+  }
+}
+```
+
+**Chain Reaction**:
+1. `subscribeToMarketUpdates()` receives event
+2. `handleMarketEvent()` processes event
+3. `handleProductEvent()` calls `marketStore.addProduct()`
+4. Store update triggers reactive effects
+5. Effects trigger new subscriptions or event processing
+6. Loop continues indefinitely
+
+#### 3. Circular Dependency in Search Results
+**Location**: `src/modules/market/views/MarketPage.vue:306-347`
+
+The computed property `productsToDisplay` created a circular dependency:
+
+```typescript
+// PROBLEMATIC LOGIC
+const productsToDisplay = computed(() => {
+  // Always used search results, even when empty search
+  let baseProducts = searchResults.value // Always reactive to search changes
+
+  // Category filtering then triggered more search updates
+  if (!hasActiveFilters.value) {
+    return baseProducts
+  }
+  // ...filtering logic that could trigger search updates
+})
+```
+
+#### 4. MarketFuzzySearch Watcher Loop
+**Location**: `src/modules/market/components/MarketFuzzySearch.vue:359-363`
+
+A watcher was immediately emitting results, creating circular updates:
+
+```typescript
+// REMOVED - CAUSED CIRCULAR DEPENDENCY
+watch(filteredItems, (items) => {
+  emit('results', items)
+}, { immediate: true })
+```
+
+**Loop**: Component emits → Parent updates → Child re-renders → Watcher fires → Component emits
+
+## Resolution Steps
+
+### Step 1: Remove Multiple Composable Instances
+```typescript
+// FIXED: Removed onMounted from useMarket composable
+// Added initialization guards
+const isInitialized = ref(false)
+const isInitializing = ref(false)
+
+const connectToMarket = async () => {
+  if (isInitialized.value || isInitializing.value) {
+    console.log('🛒 Market already connected/connecting, skipping...')
+    return { isConnected: isConnected.value }
+  }
+  isInitializing.value = true
+  // ... initialization logic
+}
+```
+
+### Step 2: Implement Event Deduplication
+```typescript
+// FIXED: Added event deduplication
+const processedEvents = ref(new Set<string>())
+
+const handleMarketEvent = (event: any) => {
+  const eventId = event.id
+  if (processedEvents.value.has(eventId)) {
+    return // Skip already processed events
+  }
+  processedEvents.value.add(eventId)
+  // ... process event
+}
+```
+
+### Step 3: Fix Search Results Logic
+```typescript
+// FIXED: Only use search results when actively searching
+const productsToDisplay = computed(() => {
+  let baseProducts: Product[]
+
+  // Only use search results if there's an actual search query
+  if (searchQuery.value && searchQuery.value.trim().length > 0) {
+    baseProducts = searchResults.value
+  } else {
+    baseProducts = [...marketStore.products] as Product[]
+  }
+  // ... category filtering
+})
+```
+
+### Step 4: Remove Problematic Watcher
+```typescript
+// REMOVED: Circular dependency watcher
+// Results now only emitted on explicit user actions:
+// - handleSearchChange()
+// - handleClear()
+// - applySuggestion()
+```
+
+## Technical Details
+
+### Vue 3 Reactive System Behavior
+The issue exploited several Vue 3 reactive system characteristics:
+
+1. **Effect Scheduling**: Computed properties and watchers are scheduled in microtasks
+2. **Circular Detection**: Vue tracks effect dependencies and detects when effects mutate their own dependencies
+3. **Recursion Limit**: Vue has a built-in limit (100 iterations) to prevent infinite loops
+
+### Nostr Protocol Considerations
+- **Event Kinds**: 30017 (stalls), 30018 (products), 30019 (markets)
+- **Real-time Updates**: Nostr subscriptions provide real-time events
+- **Event Persistence**: Same events can be received multiple times from different relays
+
+### State Management Impact
+- **Pinia Store Reactivity**: Store mutations trigger all dependent computed properties
+- **Cross-Component Effects**: State changes in one component affect others through shared store
+- **Subscription Overlap**: Multiple subscriptions to same Nostr filters cause duplicate events
+
+## Lessons Learned
+
+### 1. Composable Design Patterns
+- **Avoid side effects in composable initialization**: Don't use `onMounted` in reusable composables
+- **Implement initialization guards**: Prevent multiple simultaneous initializations
+- **Clear lifecycle management**: Explicit `initialize()` and `cleanup()` methods
+
+### 2. Event Handling Best Practices
+- **Always implement deduplication**: Track processed events by ID
+- **Idempotent operations**: Ensure repeated operations don't cause issues
+- **Defensive programming**: Handle unexpected event duplicates gracefully
+
+### 3. Vue Reactivity Guidelines
+- **Minimize circular dependencies**: Separate concerns between computed properties
+- **Careful watcher usage**: Avoid immediate watchers that emit results
+- **State isolation**: Keep reactive state changes predictable and isolated
+
+### 4. Real-time Systems
+- **Connection management**: Implement proper connection lifecycle
+- **Event ordering**: Handle out-of-order or duplicate events
+- **Resource cleanup**: Properly unsubscribe from real-time updates
+
+## Prevention Strategies
+
+### Code Review Checklist
+- [ ] No `onMounted` hooks in reusable composables
+- [ ] Event deduplication implemented for real-time systems
+- [ ] Computed properties don't create circular dependencies
+- [ ] Watchers don't immediately emit results that trigger parent updates
+- [ ] Initialization guards prevent race conditions
+
+### Testing Recommendations
+- **Stress testing**: Open/close routes repeatedly to detect initialization issues
+- **Network simulation**: Test with duplicate/delayed Nostr events
+- **Mobile testing**: Test on resource-constrained devices where issues are more likely
+
+### Monitoring & Debugging
+- **Performance monitoring**: Track recursive update warnings in production
+- **Event logging**: Log all Nostr event processing with deduplication status
+- **State transitions**: Monitor store state changes for unexpected patterns
+
+## Conclusion
+
+The recursion issue was caused by a perfect storm of multiple reactive system anti-patterns:
+1. Multiple composable instances creating overlapping effects
+2. Lack of event deduplication in real-time systems
+3. Circular dependencies in computed properties
+4. Immediate watchers causing emission loops
+
+The resolution required systematic identification and elimination of each contributing factor. The fixes implement industry best practices for Vue 3 reactive systems and real-time event processing, making the system more robust and maintainable.
+
+This incident highlights the importance of careful reactive system design, especially when combining real-time data streams with complex UI state management.

+
+## Compatibility Issues
+
+### 1. **Nostr Protocol Compliance**
+```typescript
+//  CURRENT - Missing critical Nostr fields
+const product = await nostrmarketAPI.getProduct(id)
+// Missing: pubkey, eventId, relayUrls
+
+//  SHOULD BE - Full Nostr compatibility
+const product = {
+  ...apiProduct,
+  pubkey: merchantPubkey,        // From merchant context
+  eventId: apiProduct.event_id,  // Map API field
+  relayUrls: [...relayUrls]      // From relay context
+}
+```
+
+### 2. **Configuration Mismatch**
+```typescript
+//  CURRENT - Flat structure conflicts with API
+interface Product {
+  currency: string,      // Top-level
+  description?: string   // Top-level
+}
+
+// vs API expectation:
+config: {
+  currency?: string,     // Nested
+  description?: string   // Nested
+}
+```
+
+### 3. **Event ID Handling**
+```typescript
+// Multiple formats across implementations:
+event_id        // LNbits API format
+eventId         // nostr-market-app format
+nostrEventId    // Our current format
+```
+
+---
+
+## Recommended Solutions
+
+### Option 1: **Unified Product Model** (Recommended)
+
+Create a comprehensive model that supports all three implementations:
+
+```typescript
+export interface Product {
+  // Core LNbits fields
+  id: string
+  stall_id: string
+  name: string
+  price: number
+  quantity: number
+  categories?: string[]
+  images?: string[]
+  active: boolean
+  pending: boolean
+
+  // Nostr-specific fields (CRITICAL ADDITIONS)
+  pubkey: string              //  ADD: Merchant public key
+  eventId: string            //  ADD: Nostr event ID
+  relayUrls: string[]        //  ADD: Relay URLs
+
+  // Processed fields
+  stallName: string
+  description?: string       // Top-level (matches nostr-market-app)
+  currency: string           // Top-level (matches nostr-market-app)
+  createdAt: number
+  updatedAt: number
+
+  // LNbits compatibility (optional)
+  config?: ProductConfig     // For API requests
+  event_id?: string         // LNbits format mapping
+  event_created_at?: number // LNbits format mapping
+  nostrEventId?: string     // Legacy compatibility
+}
+```
+
+### Option 2: **Type Adapters**
+
+Create adapter functions to handle different formats:
+
+```typescript
+// Type adapters for different sources
+export const adaptLNbitsToMarket = (
+  product: LNbitsProduct,
+  context: { pubkey: string; relayUrls: string[] }
+): Product => ({
+  ...product,
+  pubkey: context.pubkey,
+  eventId: product.event_id || '',
+  relayUrls: context.relayUrls,
+  currency: product.config?.currency || 'sats',
+  description: product.config?.description,
+  createdAt: product.event_created_at || Date.now(),
+  updatedAt: Date.now()
+})
+
+export const adaptNostrToMarket = (
+  product: NostrProduct
+): Product => ({
+  // Direct mapping for nostr-market-app format
+  ...product,
+  // Additional processing as needed
+})
+```
+
+### Option 3: **Progressive Enhancement**
+
+Gradually add missing fields without breaking existing functionality:
+
+```typescript
+// Phase 1: Add critical Nostr fields
+export interface Product extends CurrentProduct {
+  pubkey?: string         // Optional for backward compatibility
+  eventId?: string       // Optional for backward compatibility
+  relayUrls?: string[]   // Optional for backward compatibility
+}
+
+// Phase 2: Implement field population
+// Phase 3: Make fields required
+```
+
+---
+
+## Implementation Priority
+
+### **Phase 1: Critical Fixes** (High Priority)
+1. Add `pubkey` field to Product model
+2. Map `event_id` to `eventId` consistently
+3. Add `relayUrls` array
+4. Update type definitions
+
+### **Phase 2: Structure Alignment** (Medium Priority)
+1. Implement configuration adapters
+2. Standardize currency/description placement
+3. Add active/pending state handling
+
+### **Phase 3: Full Compatibility** (Future)
+1. Implement complete nostr-market-app compatibility
+2. Add relay management features
+3. Implement proper Nostr event handling
+
+---
+
+## Testing Requirements
+
+### Unit Tests Needed
+```typescript
+describe('Product Model Compatibility', () => {
+  test('should adapt LNbits API format to unified format', () => {
+    const lnbitsProduct = { /* LNbits format */ }
+    const context = { pubkey: 'abc123', relayUrls: ['wss://relay.com'] }
+
+    const result = adaptLNbitsToMarket(lnbitsProduct, context)
+
+    expect(result.pubkey).toBe('abc123')
+    expect(result.relayUrls).toContain('wss://relay.com')
+    expect(result.currency).toBeDefined()
+  })
+
+  test('should maintain backward compatibility', () => {
+    const currentProduct = { /* Current format */ }
+
+    // Should not break existing functionality
+    expect(() => processProduct(currentProduct)).not.toThrow()
+  })
+})
+```
+
+### Integration Tests
+1. API compatibility with LNbits
+2. Nostr event processing compatibility
+3. Market store operations
+4. UI component rendering
+
+---
+
+## Migration Plan
+
+### **Immediate Actions**
+1.  Document current state (this analysis)
+2.  Update Product interface with optional Nostr fields
+3.  Implement adapter functions
+4.  Add field population in MerchantStore.vue
+
+### **Short Term** (1-2 weeks)
+1. Make Nostr fields required
+2. Update all product processing logic
+3. Add comprehensive tests
+4. Update documentation
+
+### **Long Term** (1-2 months)
+1. Full nostr-market-app compatibility
+2. Advanced Nostr features
+3. Performance optimization
+4. Enhanced relay management
+
+---
+
+## Conclusion
+
+The analysis reveals **critical gaps** in our current Product model that limit full Nostr marketplace compatibility. The missing `pubkey`, `eventId`, and `relayUrls` fields are essential for proper Nostr protocol integration.
+
+**Recommended Immediate Action:** Implement Option 1 (Unified Product Model) with progressive enhancement to maintain backward compatibility while adding essential Nostr functionality.
+
+**Success Criteria:**
+-  Full compatibility with nostr-market-app reference implementation
+-  Maintained LNbits API integration
+-  No breaking changes to existing functionality
+-  Enhanced Nostr marketplace capabilities

+# WebSocket Connection Issues - Troubleshooting Report
+
+## Executive Summary
+
+The wallet module's WebSocket connection for real-time balance updates fails to establish when connecting through certain network configurations. While a polling-based fallback was successfully implemented, the root cause of the WebSocket failure remains unresolved.
+
+## Problem Description
+
+### Symptoms
+- WebSocket connection to `wss://lnbits.ario.pm/api/v1/ws/<wallet-id>` fails immediately
+- Error message: `WebSocket connection failed`
+- Connection attempts result in immediate closure
+- Issue appears related to network path through WireGuard VPN and/or nginx proxy
+
+### Current Configuration
+
+#### Network Path
+```
+Client Browser → Internet → nginx (reverse proxy) → WireGuard VPN → LNbits Server
+```
+
+#### nginx Configuration
+- Reverse proxy at `lnbits.ario.pm`
+- Standard WebSocket proxy headers configured
+- HTTPS/WSS termination at nginx level
+
+#### LNbits Server
+- Running behind WireGuard VPN
+- WebSocket endpoint: `/api/v1/ws/<wallet-id>`
+- Requires `X-Api-Key` header for authentication
+
+## Root Cause Analysis
+
+### Confirmed Working
+- ✅ Standard HTTPS API calls work perfectly
+- ✅ Authentication headers are properly passed
+- ✅ LNbits server WebSocket endpoint is functional (works in direct connections)
+- ✅ Polling fallback successfully retrieves balance updates
+
+### Potential Causes
+
+#### 1. **nginx WebSocket Proxy Configuration**
+**Likelihood: HIGH**
+
+Standard nginx configurations often miss critical WebSocket headers:
+```nginx
+# Required headers that might be missing
+proxy_http_version 1.1;
+proxy_set_header Upgrade $http_upgrade;
+proxy_set_header Connection "upgrade";
+proxy_set_header Host $host;
+proxy_set_header X-Real-IP $remote_addr;
+proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
+proxy_set_header X-Forwarded-Proto $scheme;
+
+# WebSocket-specific timeout settings
+proxy_connect_timeout 60s;
+proxy_send_timeout 60s;
+proxy_read_timeout 60s;
+```
+
+**Solution**: Verify nginx configuration includes proper WebSocket upgrade headers and timeout settings.
+
+#### 2. **WireGuard MTU Issues**
+**Likelihood: MEDIUM**
+
+WireGuard default MTU (1420) can cause packet fragmentation issues with WebSocket frames:
+- WebSocket frames might exceed MTU after VPN encapsulation
+- Fragmented packets may be dropped or delayed
+
+**Solution**:
+```bash
+# In WireGuard config
+[Interface]
+MTU = 1380  # Reduced MTU to account for overhead
+```
+
+#### 3. **NAT/Connection Tracking**
+**Likelihood: MEDIUM**
+
+Long-lived WebSocket connections can be terminated by:
+- NAT timeout settings
+- Connection tracking table exhaustion
+- Firewall state timeout
+
+**Solution**:
+- Increase NAT timeout values
+- Enable WebSocket keepalive/ping frames
+- Configure firewall to recognize WebSocket as persistent connection
+
+#### 4. **HTTP/2 Incompatibility**
+**Likelihood: MEDIUM**
+
+WebSockets don't work over HTTP/2 connections:
+- If nginx is configured for HTTP/2, WebSocket upgrade fails
+- Need separate location block or HTTP/1.1 fallback
+
+**Solution**:
+```nginx
+location /api/v1/ws {
+    proxy_http_version 1.1;  # Force HTTP/1.1
+    # ... other WebSocket headers
+}
+```
+
+#### 5. **Header Size/Authentication Issues**
+**Likelihood: LOW**
+
+Custom headers might be stripped or modified:
+- `X-Api-Key` header might not survive proxy chain
+- Header size limits in proxy configuration
+
+**Solution**: Verify headers are properly forwarded through entire chain.
+
+## Diagnostic Steps
+
+### 1. Browser-Level Debugging
+```javascript
+// Test WebSocket connection directly
+const ws = new WebSocket('wss://lnbits.ario.pm/api/v1/ws/wallet-id');
+
+ws.onopen = () => console.log('Connected');
+ws.onerror = (error) => console.error('Error:', error);
+ws.onclose = (event) => {
+  console.log('Close code:', event.code);
+  console.log('Close reason:', event.reason);
+  console.log('Was clean:', event.wasClean);
+};
+```
+
+### 2. Network Path Testing
+```bash
+# Test from different network locations
+# 1. Direct to LNbits (bypassing nginx)
+wscat -c ws://lnbits-server:5000/api/v1/ws/wallet-id -H "X-Api-Key: key"
+
+# 2. Through nginx (bypassing WireGuard)
+wscat -c wss://nginx-server/api/v1/ws/wallet-id -H "X-Api-Key: key"
+
+# 3. Full path (through nginx and WireGuard)
+wscat -c wss://lnbits.ario.pm/api/v1/ws/wallet-id -H "X-Api-Key: key"
+```
+
+### 3. nginx Logs Analysis
+```bash
+# Check nginx error logs
+tail -f /var/log/nginx/error.log | grep -i websocket
+
+# Enable debug logging for WebSocket
+error_log /var/log/nginx/error.log debug;
+```
+
+### 4. WireGuard Diagnostics
+```bash
+# Check for packet drops
+wg show
+ip -s link show wg0
+
+# Monitor MTU issues
+tcpdump -i wg0 -n 'tcp[tcpflags] & (tcp-syn) != 0'
+```
+
+## Implemented Workaround
+
+### Polling Fallback Mechanism
+```typescript
+// WalletWebSocketService.ts
+class WalletWebSocketService extends BaseService {
+  private async startPolling() {
+    this.stopPolling()
+
+    const pollBalance = async () => {
+      if (!this.isActive) return
+
+      try {
+        const walletDetails = await this.walletAPI.getWalletDetails()
+        if (walletDetails && walletDetails.balance !== this.lastBalance) {
+          this.lastBalance = walletDetails.balance
+          this.store.updateBalance(walletDetails.balance / 1000)
+          this.emit('balance-updated', walletDetails.balance / 1000)
+        }
+      } catch (error) {
+        console.error('[WalletWebSocketService] Polling error:', error)
+      }
+    }
+
+    // Initial poll
+    await pollBalance()
+
+    // Set up recurring polls
+    this.pollInterval = setInterval(pollBalance, 5000) // Poll every 5 seconds
+  }
+}
+```
+
+### Fallback Behavior
+- Automatically activates when WebSocket connection fails
+- Polls `/api/v1/wallets` endpoint every 5 seconds
+- Updates balance only when changes detected
+- Maintains same event emission pattern as WebSocket
+
+## Recommended Solutions
+
+### Priority 1: nginx Configuration Audit
+1. Review nginx WebSocket proxy configuration
+2. Add missing WebSocket headers
+3. Ensure proper timeout settings
+4. Test with HTTP/1.1 forced for WebSocket endpoints
+
+### Priority 2: Network Path Optimization
+1. Test WebSocket connection at each network hop
+2. Adjust WireGuard MTU if fragmentation detected
+3. Review firewall/NAT rules for long-lived connections
+
+### Priority 3: Enhanced Diagnostics
+1. Add WebSocket connection diagnostics endpoint
+2. Implement client-side connection state reporting
+3. Add server-side WebSocket connection logging
+
+### Priority 4: Alternative Approaches
+1. Consider Server-Sent Events (SSE) as alternative to WebSockets
+2. Implement WebSocket connection through separate subdomain
+3. Use WebSocket-specific reverse proxy (e.g., websockify)
+
+## Testing Checklist
+
+- [ ] Verify nginx configuration includes all WebSocket headers
+- [ ] Test WebSocket connection from different network locations
+- [ ] Check nginx error logs for WebSocket-specific errors
+- [ ] Monitor WireGuard interface for packet drops
+- [ ] Test with reduced MTU settings
+- [ ] Verify authentication headers are properly forwarded
+- [ ] Test with HTTP/1.1 forced for WebSocket location
+- [ ] Check firewall/NAT timeout settings
+- [ ] Test with browser developer tools WebSocket inspector
+- [ ] Verify LNbits server WebSocket endpoint directly
+
+## Future Improvements
+
+### Short-term
+1. Add connection retry logic with exponential backoff
+2. Implement WebSocket heartbeat/ping mechanism
+3. Add detailed connection state logging
+4. Create health check endpoint for WebSocket connectivity
+
+### Long-term
+1. Implement connection quality monitoring
+2. Add automatic fallback selection based on network conditions
+3. Consider implementing WebRTC DataChannel as alternative
+4. Evaluate HTTP/3 WebTransport when available

+✓ No TypeScript errors
+✓ No type warnings
+```
+
+### Console Log Audit
+
+**Remaining console statements:** 21 (all appropriate)
+
+| Type | Count | Purpose |
+|------|-------|---------|
+| `console.error` | 9 | Critical errors (send message failed, API errors, etc.) |
+| `console.warn` | 12 | Important warnings (missing services, auth issues, etc.) |
+| `console.log` | 0 | ✅ All debug logs removed |
+| `console.debug` | 0 | ✅ None present |

+
+### Build Verification
+
+```
+✓ Production build successful
+✓ Bundle size: 836.25 kB (gzipped: 241.66 kB)
+✓ PWA precache: 51 entries (2365.73 kB)
+✓ Image optimization: 69% savings
+```
+
+---
+
+## Architectural Improvements
+
+### 1. Single Source of Truth Pattern
+
+**Before:**
+```typescript
+// Component had its own sorting logic
+const sortedPeers = computed(() => {
+  return [...peers.value].sort((a, b) => {
+    // Sort by unread count, then alphabetically (WRONG!)
+  })
+})
+```
+
+**After:**
+```typescript
+// Service is the single source of truth
+// Component uses service sorting directly
+const { filteredItems: filteredPeers } = useFuzzySearch(peers, { ... })
+```
+
+### 2. Lazy Initialization Pattern
+
+**Before:**
+```typescript
+constructor() {
+  // Too early - StorageService not available!
+  this.notificationStore = useChatNotificationStore()
+}
+```
+
+**After:**
+```typescript
+private async completeInitialization() {
+  // Initialize only when dependencies are ready
+  if (!this.notificationStore) {
+    this.notificationStore = useChatNotificationStore()
+    this.notificationStore.loadFromStorage()
+  }
+}
+```
+
+### 3. Defensive Programming
+
+**Added:**
+```typescript
+// Skip current user - you can't chat with yourself!
+if (currentUserPubkey && peer.pubkey === currentUserPubkey) {
+  return
+}
+```
+
+### 4. Activity-Based Sorting
+
+**Algorithm:**
+1. Uses actual message timestamps (source of truth)
+2. Fallback to stored timestamps if no messages
+3. Active peers (activity > 0) always appear first
+4. Sort by recency (descending)
+5. Stable tiebreaker by pubkey (prevents random reordering)
+
