Migrate DiscoverView.vue to Enhanced Triple Migration Pattern

- Replaced all databaseUtil and direct PlatformServiceFactory usage with PlatformServiceMixin methods
- Removed all raw SQL queries from the component
- Centralized all notification messages in src/constants/notifications.ts
- Replaced direct $notify calls with notification helpers and TIMEOUTS constants
- Streamlined template logic (tab classes via computed properties)
- Updated migration documentation and security audit
- Ran lint-fix; no errors remain

Ready for human testing and validation.

+# DiscoverView.vue Migration Documentation
+
+**Migration Start**: 2025-07-08 12:11 UTC  
+**Component**: DiscoverView.vue  
+**Priority**: High (Critical User Journey)  
+**Location**: `src/views/DiscoverView.vue`
+
+## Pre-Migration Analysis
+
+### 🔍 **Current State Assessment**
+
+#### Database Operations
+- **Legacy Pattern**: Uses `databaseUtil.retrieveSettingsForActiveAccount()` (line 396)
+- **Legacy Pattern**: Uses `databaseUtil.mapQueryResultToValues()` (line 405)
+- **Direct PlatformService**: Uses `PlatformServiceFactory.getInstance()` (line 403)
+- **Raw SQL**: Uses `"SELECT * FROM contacts"` (line 404)
+
+#### Notification Usage
+- **Direct $notify Calls**: 3 instances found (lines 515, 607, 758)
+- **Notification Types**: danger, warning, success
+- **Messages**: Error handling, search results, loading status
+
+#### Template Complexity
+- **Conditional Rendering**: Multiple v-if/v-else conditions for tabs
+- **Dynamic Content**: Complex search results and map integration
+- **User Interactions**: Search functionality, map interactions, infinite scroll
+
+### 📊 **Migration Complexity Assessment**
+- **Database Migration**: Medium (2 database operations)
+- **SQL Abstraction**: Low (1 raw SQL query)
+- **Notification Migration**: Medium (3 notifications)
+- **Template Streamlining**: High (complex conditionals and interactions)
+
+### 🎯 **Migration Goals**
+1. Replace `databaseUtil` calls with PlatformServiceMixin methods
+2. Abstract raw SQL with service methods
+3. Extract all notification messages to constants
+4. Replace `$notify()` calls with helper methods
+5. Streamline template with computed properties
+
+## Migration Plan
+
+### **Phase 1: Database Migration**
+```typescript
+// Replace databaseUtil.retrieveSettingsForActiveAccount()
+const settings = await this.$accountSettings();
+
+// Replace PlatformServiceFactory.getInstance() + raw SQL
+const allContacts = await this.$getAllContacts();
+
+// Replace databaseUtil.mapQueryResultToValues()
+// This will be handled by the service method above
+```
+
+### **Phase 2: Notification Migration**
+```typescript
+// Extract to constants
+NOTIFY_DISCOVER_SEARCH_ERROR
+NOTIFY_DISCOVER_LOCAL_SEARCH_ERROR
+NOTIFY_DISCOVER_MAP_SEARCH_ERROR
+
+// Replace direct $notify calls with helper methods
+this.notify.error(NOTIFY_DISCOVER_SEARCH_ERROR.message, TIMEOUTS.LONG);
+```
+
+### **Phase 3: Template Streamlining**
+```typescript
+// Extract complex conditional classes to computed properties
+computedProjectsTabStyleClassNames()
+computedPeopleTabStyleClassNames()
+computedLocalTabStyleClassNames()
+computedMappedTabStyleClassNames()
+computedRemoteTabStyleClassNames()
+```
+
+## Migration Implementation
+
+### **Step 1: Add PlatformServiceMixin**
+```typescript
+import { PlatformServiceMixin } from "@/utils/PlatformServiceMixin";
+
+@Component({
+  components: {
+    // ... existing components
+  },
+  mixins: [PlatformServiceMixin],
+})
+```
+
+### **Step 2: Add Notification Infrastructure**
+```typescript
+import { createNotifyHelpers, TIMEOUTS } from "@/utils/notify";
+import {
+  NOTIFY_DISCOVER_SEARCH_ERROR,
+  NOTIFY_DISCOVER_LOCAL_SEARCH_ERROR,
+  NOTIFY_DISCOVER_MAP_SEARCH_ERROR,
+} from "@/constants/notifications";
+
+// Add property
+notify!: ReturnType<typeof createNotifyHelpers>;
+
+// Initialize in created()
+created() {
+  this.notify = createNotifyHelpers(this.$notify);
+}
+```
+
+### **Step 3: Replace Database Operations**
+```typescript
+// In mounted() method
+const settings = await this.$accountSettings();
+this.allContacts = await this.$getAllContacts();
+```
+
+### **Step 4: Replace Notification Calls**
+```typescript
+// Replace error notifications
+this.notify.error(NOTIFY_DISCOVER_SEARCH_ERROR.message, TIMEOUTS.LONG);
+this.notify.error(NOTIFY_DISCOVER_LOCAL_SEARCH_ERROR.message, TIMEOUTS.LONG);
+this.notify.error(NOTIFY_DISCOVER_MAP_SEARCH_ERROR.message, TIMEOUTS.LONG);
+```
+
+## Expected Outcomes
+
+### **Technical Improvements**
+- ✅ All database operations use PlatformServiceMixin
+- ✅ No raw SQL queries in component
+- ✅ All notifications use helper methods and constants
+- ✅ Template logic streamlined with computed properties
+- ✅ Consistent error handling patterns
+
+### **Functional Preservation**
+- ✅ Search functionality (local, mapped, anywhere) preserved
+- ✅ Map integration and tile loading preserved
+- ✅ Infinite scroll functionality preserved
+- ✅ Tab switching and state management preserved
+- ✅ Error handling and user feedback preserved
+
+### **Performance Improvements**
+- ✅ Reduced database query complexity
+- ✅ Standardized notification patterns
+- ✅ Optimized template rendering
+- ✅ Better error handling efficiency
+
+## Testing Requirements
+
+### **Functional Testing**
+- [ ] Search functionality works for all tabs (Projects, People)
+- [ ] Local search with location selection works
+- [ ] Mapped search with map integration works
+- [ ] Anywhere search with infinite scroll works
+- [ ] Error handling displays appropriate notifications
+- [ ] Tab switching preserves state correctly
+
+### **Cross-Platform Testing**
+- [ ] Web browser functionality
+- [ ] Mobile app functionality (Capacitor)
+- [ ] Desktop app functionality (Electron)
+- [ ] PWA functionality
+
+### **Error Scenario Testing**
+- [ ] Network connectivity issues
+- [ ] Invalid search parameters
+- [ ] Empty search results
+- [ ] Map loading failures
+- [ ] Database connection issues
+
+## Security Audit Checklist
+
+### **SQL Injection Prevention**
+- [ ] No raw SQL queries in component
+- [ ] All database operations use parameterized queries
+- [ ] Input validation for search terms
+- [ ] Proper error handling without information disclosure
+
+### **Data Privacy**
+- [ ] User search terms properly sanitized
+- [ ] Location data handled securely
+- [ ] Contact information access controlled
+- [ ] No sensitive data in error messages
+
+### **Input Validation**
+- [ ] Search terms validated and sanitized
+- [ ] Map coordinates validated
+- [ ] URL parameters properly handled
+- [ ] File uploads (if any) validated
+
+## Migration Timeline
+
+### **Estimated Duration**: 25-35 minutes
+- **Phase 1 (Database)**: 8-10 minutes
+- **Phase 2 (SQL)**: 3-5 minutes
+- **Phase 3 (Notifications)**: 8-10 minutes
+- **Phase 4 (Template)**: 6-10 minutes
+
+### **Risk Assessment**
+- **Functionality Risk**: Low (search is well-contained)
+- **Data Risk**: Low (read-only operations)
+- **User Impact**: Low (feature is secondary to main workflow)
+
+### **Dependencies**
+- PlatformServiceMixin availability
+- Notification constants in place
+- Map component integration preserved
+- Search API endpoints accessible
