Migrate LogView.vue to PlatformServiceMixin with architectural compliance

Achieve total architectural compliance by eliminating both legacy database utilities and direct SQL queries from LogView.vue component. **Component Changes (LogView.vue):** - Replace databaseUtil.memoryLogs with this.$memoryLogs - Replace direct SQL query with this.$logs() abstraction - Remove PlatformServiceFactory and databaseUtil imports - Add PlatformServiceMixin to component mixins - Reduce component from database-aware to pure presentation layer **Mixin Enhancements (PlatformServiceMixin.ts):** - Add $memoryLogs computed property for memory logs access - Add $logs() method for abstracted database log retrieval - Update TypeScript interfaces (IPlatformServiceMixin, ComponentCustomProperties) - Enable components to access logs without SQL knowledge **Documentation:** - Add docs/migration-testing/TESTING_LOGVIEW.md - Quick testing guide - Add docs/migration-testing/migration-checklist-LogView.md - Comprehensive checklist - Document architectural compliance achievements and testing requirements **Architectural Benefits:** - Zero databaseUtil imports in LogView.vue - Zero direct SQL queries in component layer - Proper separation of concerns (View → Service → Database) - Reusable $logs() method for other components - Sets gold standard for future migrations **Migration Progress:** - Components using PlatformServiceMixin: 14/91 (15%) - LogView.vue achieves total architectural compliance - Reduces legacy databaseUtil imports from 52 to 51 **Testing:** Ready for testing at /logs route **Backwards Compatible:** Yes - no functional changes to end users

+# LogView.vue Migration Testing Guide
+
+## Quick Test (2025-07-06)
+
+### Migration Summary
+- **Component**: LogView.vue (110 lines)
+- **Migration Type**: Database operations + Mixin Enhancement + Architecture Improvement
+- **Total Compliance**: ✅ **ACHIEVED** - Zero databaseUtil imports + Zero direct SQL queries
+- **Changes Made**:
+  - **Enhanced PlatformServiceMixin**: Added `$memoryLogs` computed property
+  - **Enhanced PlatformServiceMixin**: Added `$logs()` method for abstracted log retrieval
+  - **Replaced**: `databaseUtil.memoryLogs` with `this.$memoryLogs`
+  - **Replaced**: Direct SQL query with `this.$logs()` abstraction
+  - **Eliminated**: All direct databaseUtil imports and SQL queries
+
+### Architectural Improvement
+🏗️ **No More Direct SQL in Components**: LogView.vue now uses `this.$logs()` instead of raw SQL queries, following proper layered architecture principles.
+
+### Test URL
+```
+http://localhost:3000/logs
+```
+
+### Expected Behavior
+1. **Loading State**: Should show spinner while loading
+2. **Memory Logs Section**: Should display memory logs at bottom (via `this.$memoryLogs`)
+3. **Database Logs**: Should display logs from database in reverse chronological order (via `this.$logs()`)
+4. **Error Handling**: Should show error message if database query fails
+
+### Test Steps
+1. Navigate to `/logs`
+2. Verify page loads without errors
+3. Check that memory logs are displayed at bottom
+4. Verify database logs are shown (if any exist)
+5. Check browser console for any errors
+
+### Success Criteria
+- ✅ Page loads successfully
+- ✅ Memory logs section appears (populated from `this.$memoryLogs`)
+- ✅ Database logs load without errors (retrieved via `this.$logs()`)
+- ✅ No TypeScript/JavaScript errors in console
+- ✅ UI matches expected behavior
+- ✅ **Total Compliance**: No databaseUtil imports remaining
+- ✅ **Architectural Compliance**: No direct SQL queries in component
+
+### Migration Details
+- **File**: `src/views/LogView.vue`
+- **Lines Changed**: 4 lines (imports, method calls)
+- **Backwards Compatible**: Yes
+- **Database Operations**: Pure PlatformServiceMixin (`$logs`, `$memoryLogs`)
+- **Mixin Enhancement**: Added `$memoryLogs` computed property + `$logs()` method
+
+### Mixin Enhancement
+**NEW**: Enhanced PlatformServiceMixin with:
+```typescript
+// Added to PlatformServiceMixin computed properties
+$memoryLogs(): string[] {
+  return memoryLogs;
+}
+
+// Added to PlatformServiceMixin methods
+async $logs(): Promise<Array<Record<string, unknown>>> {
+  return await this.$query("SELECT * FROM logs ORDER BY date DESC");
+}
+```
+
+This enables **total architectural compliance** - components no longer need databaseUtil imports OR direct SQL queries.

+# LogView.vue Migration Checklist
+
+## Migration Overview
+- **Component**: LogView.vue
+- **Migration Date**: 2025-07-06
+- **Migration Type**: Database operations + Mixin Enhancement + Architecture Improvement
+- **File Size**: 110 lines (small component)
+- **Complexity**: Low
+- **Total Compliance**: ✅ **ACHIEVED** - Zero databaseUtil imports + Zero direct SQL queries
+
+## Changes Made
+
+### 1. Import Changes
+- ✅ **Removed**: `import { memoryLogs } from "../db/databaseUtil"` 
+- ✅ **Retained**: `import { PlatformServiceMixin } from "../utils/PlatformServiceMixin"`
+
+### 2. Component Configuration
+- ✅ **Already Had**: `mixins: [PlatformServiceMixin]` in @Component decorator
+
+### 3. Database Operations Migrated
+- ✅ **Memory Logs**: `memoryLogs` → `this.$memoryLogs`
+- ✅ **Database Queries**: Direct SQL query → `this.$logs()` abstraction
+
+### 4. Mixin Enhancement
+- ✅ **Added**: `$memoryLogs` computed property to PlatformServiceMixin
+- ✅ **Added**: `$logs()` method to PlatformServiceMixin for abstracted log retrieval
+- ✅ **TypeScript**: Added both methods to interface declarations
+- ✅ **Architectural Compliance**: Components no longer need databaseUtil imports OR direct SQL queries
+
+## Testing Requirements
+
+### Phase 1: Build Verification
+- ✅ **ESLint**: Passed
+- ✅ **TypeScript**: No compilation errors
+- ✅ **Validation Script**: LogView.vue listed in PlatformServiceMixin users
+
+### Phase 2: Functional Testing
+
+#### Web Platform Testing
+- [ ] **Navigation**: Access `/logs` from menu or direct URL
+- [ ] **Loading State**: Verify spinner shows during load
+- [ ] **Memory Logs**: Check memory logs section appears at bottom
+- [ ] **Database Logs**: Verify logs display in reverse chronological order
