+## Integration Test Results - FINAL
 
 **Test Summary:**
-- 496 tests PASSED ✓
-- 24 tests FAILED (object storage directory setup issue)
-- 7 tests SKIPPED
+- ✅ 520 tests PASSED
+- ⏭️  7 tests SKIPPED
+- ❌ 0 tests FAILED
 
-**Failed tests:** All 24 failures in test_object.py and test_update1.py are due to:
-`FileNotFoundError: Inaccessible local directory`
+**All tests passing!**
 
-This is a test fixture issue with temporary directory creation for object storage tests, not related to the unified stores configuration changes.
+### Initial Issues Found and Fixed
 
-**Core functionality verified:**
-- All configuration tests passing
-- All blob tests passing
-- All relation/query tests passing
-- All schema/table tests passing
-- Store configuration and validation working correctly
+Initial run had 24 failures in object storage tests due to test fixture bug:
+- `conftest.py`: object_storage_config wasn't creating the `test_project` subdirectory
+- `test_update1.py`: mock_stores_update wasn't creating `djtest` subdirectories
+
+**Root cause:** Test fixtures were configuring storage locations but not creating
+the directories. StorageBackend validates that file protocol locations exist
+during initialization.
+
+**Fix:** Added `Path(location).mkdir(parents=True, exist_ok=True)` in both fixtures.
+
+### Test Coverage Verified
+
+All unified stores configuration functionality tested:
+- ✅ Configuration system with stores.default and stores.filepath_default
+- ✅ Prefix validation and separation (hash_prefix, schema_prefix, filepath_prefix)
+- ✅ Filepath codec validation with dynamic prefix checking
+- ✅ Store backend initialization and validation
+- ✅ Object storage (file, stream, folder operations)
+- ✅ Hash-addressed storage (blob, attach)
+- ✅ Schema-addressed storage (object, npy)
+- ✅ All relational operators and queries
+- ✅ Schema management and dependencies
