+# Property Testing Cleanup Summary
+
+## 🧹 Cleanup Completed
+
+### **Files Removed**
+- ✅ `debug-property-test.test.ts` - Debug test file
+- ✅ `example.ts` - Example script file  
+- ✅ `simple-example.ts` - Simple example script file
+- ✅ `sql/mock-sqlite-oracle.ts` - Mock SQLite oracle (never use mocks!)
+
+### **Files Renamed for Clarity**
+- ✅ `actual-property-tests.test.ts` → `property-based-tests.test.ts`
+- ✅ `enhanced-quick-tests.test.ts` → `quick-test-suite.test.ts`
+- ✅ `property-tests.test.ts` → `framework-unit-tests.test.ts`
+- ✅ `sql-comparison.test.ts` → `tanstack-sqlite-comparison.test.ts`
+- ✅ `query-builder-ir.test.ts` → `query-builder-ir-extraction.test.ts`
+- ✅ `ir-to-sql.test.ts` → `ir-to-sql-translation.test.ts`
+
+### **Debug Code Removed**
+- ✅ Removed all `console.log` statements from test files
+- ✅ Removed debug output from test assertions
+- ✅ Kept only essential error logging in property test harness
+
+### **Mock Oracle Removed**
+- ✅ Completely removed `MockSQLiteOracle` class
+- ✅ Removed `createMockDatabase` functions
+- ✅ Removed all references to mock SQLite oracle
+- ✅ Only real `better-sqlite3` oracle remains

+
+## ✅ Quality Assurance
+
+- ✅ **Zero linting issues** - All ESLint rules satisfied
+- ✅ **Clean code** - No debug statements or unused code
+- ✅ **Clear naming** - All files have descriptive names
+- ✅ **Real oracle only** - No mock implementations
+- ✅ **Tests passing** - All functionality preserved
+- ✅ **Ready for production** - Can be safely merged
+
+## 🎯 Purpose of Each Test File
+
+| File | Purpose |
+|------|---------|
+| `property-based-tests.test.ts` | Main property-based testing of query engine |
+| `quick-test-suite.test.ts` | Fast infrastructure validation |
+| `framework-unit-tests.test.ts` | Unit tests for framework components |
+| `comprehensive-sql-coverage.test.ts` | Complete SQL translation coverage |
+| `tanstack-sqlite-comparison.test.ts` | TanStack DB vs SQLite comparison |
+| `query-builder-ir-extraction.test.ts` | IR extraction from query builder |
+| `ir-to-sql-translation.test.ts` | IR to SQL translation validation |
+
+## 🚀 Ready for Production
+
+The property testing framework is now:
+- **Clean** - No debug code or unused files
+- **Clear** - Descriptive file names and structure
+- **Real** - Only uses real SQLite oracle
+- **Reliable** - All tests passing and linting clean
+- **Ready** - Can be safely integrated into main codebase
