-### ✅ Completed
+### ✅ COMPLETED - ALL PHASES
 - **Phase 1-2**: Package structure and code movement complete
-- **Phase 3**: Circular imports resolved, ScmVersion in _version_schemes
-- **Phase 4**: uv workspace configured, both packages build successfully
-- **Phase 5**: Backward compatibility layer complete with re-export stubs
-- **License fix**: Updated pyproject.toml to use SPDX license format
-- **Test imports**: All 419 tests collected successfully
-- **Private API separation**: Tests import private APIs from vcs_versioning directly
-
-### 🔄 In Progress
-- **Phase 6**: Test suite fixes (5/19 passing in test_basic_api)
-- **Legacy API compatibility**: get_version() needs parameter handling
+- **Phase 3**: Backward compatibility layer complete
+  - Circular imports resolved, ScmVersion in _version_schemes
+  - Re-export stubs in setuptools_scm for backward compatibility
+- **Phase 4**: Public API properly exported
+  - vcs_versioning exports Configuration, ScmVersion, Version
+  - setuptools_scm re-exports for backward compatibility
+- **Phase 5**: Integration layer rebuilt
+  - setuptools_scm depends on vcs-versioning
+  - Entry points properly distributed between packages
+  - File finders remain in setuptools_scm
+- **Phase 6**: Test migration complete
+  - VCS-agnostic tests moved to vcs-versioning (79 tests)
+  - Integration tests remain in setuptools_scm (329 tests)
+  - All test imports fixed to use correct modules
+- **Phase 7**: Progress tracked with regular commits
+- **Phase 8**: CI/CD ready
+  - uv workspace configured
+  - Both packages build successfully
+  - Test suite passes locally
+
+### 🎉 Logging Unification Complete
+- **Separate root loggers** for vcs_versioning and setuptools_scm
+- **Entry point configuration** at CLI and setuptools integration
+- **Central logger registry** with LOGGER_NAMES
+- **Environment variables**: VCS_VERSIONING_DEBUG and SETUPTOOLS_SCM_DEBUG
+- **Standard logging pattern**: All modules use logging.getLogger(__name__)
 
 ### 📦 Build Status
 - `uv sync` successful
-- Both packages install: setuptools-scm 9.2.2.dev12, vcs-versioning 0.0.1
-- Tests can be collected and run
-
-### 🧪 Test Status
-- **vcs-versioning**: 79/79 tests passing (test_compat, test_internal_log_level, test_version)
-- **setuptools_scm**: 419 tests collected, integration tests running
-- Src layout implemented in both packages
+- setuptools-scm: version 9.2.2.dev20+g6e22672.d20251012
+- vcs-versioning: version 0.0.1
+- Both packages install and import correctly
+
+### 🧪 Test Results - ALL PASSING ✅
+- **vcs-versioning**: 79 passed
+- **setuptools_scm**: 329 passed, 10 skipped, 1 xfailed
+- **Total**: 408 tests passing
+- Test run time: ~15s with parallel execution
+
+### 🔧 Key Fixes Applied
+1. Empty tag regex deprecation warning properly emitted
+2. Test mocks patching actual module locations
+3. Missing backward compat imports (strip_path_suffix, __main__.py)
+4. setuptools.dynamic.version conflict warning
+5. Test patches for _git module vs re-exported git
