+# geosPythonPackages CI/CD Documentation
+
+This document explains the Continuous Integration (CI) setup for the geosPythonPackages repository.
+
+## Overview
+
+The CI system consists of two main workflows:
+
+1. **`python-package.yml`** - Tests all Python packages individually
+2. **`test_geos_integration.yml`** - Tests integration with the GEOS simulation framework
+
+## Workflow 1: Python Package Testing (`python-package.yml`)
+
+### Purpose
+Tests each Python package independently to ensure:
+- Code quality (linting with yapf)
+- Functionality (unit tests with pytest)
+- Python version compatibility (3.10, 3.11, 3.12)
+- VTK version compatibility (>= 9.3)
+
+### Tested Packages
+- `geos-ats` - Automated Testing System for GEOS
+- `geos-geomechanics` - Geomechanics analysis tools
+- `geos-mesh` - Mesh conversion and validation tools
+- `geos-posp` - Post-processing utilities
+- `geos-timehistory` - Time history analysis
+- `geos-trame` - Trame-based visualization
+- `geos-utils` - Utility functions
+- `geos-xml-tools` - XML preprocessing and formatting
+- `geos-xml-viewer` - XML viewing tools
+- `hdf5-wrapper` - HDF5 file handling wrapper
+- `pygeos-tools` - GEOS Python tools
+
+### Jobs
+
+#### 1. Semantic Pull Request Check
+```yaml
+semantic_pull_request:
+  - Validates PR title follows conventional commits format
+  - Required format: `type: description` or `type(scope): description`
+  - Examples: `feat: add new feature`, `fix(mesh): resolve bug`
+```
+
+#### 2. Build and Test
+```yaml
+build:
+  - Matrix testing across Python 3.10, 3.11, 3.12
+  - Installs package dependencies
+  - Lints code with yapf
+  - Runs pytest tests
+```
+
+#### 3. GEOS Integration Check
+```yaml
+check_geos_integration_required:
+  - Analyzes changed files
+  - Determines if GEOS integration tests are needed
+  - See "Smart GEOS Integration Testing" section below
+```
+
+#### 4. GEOS Integration Test (Conditional)
+```yaml
+geos_integration_test:
+  - Only runs if required by file changes or label
+  - Calls test_geos_integration.yml workflow
+```
+
+#### 5. Final Validation
+```yaml
+final_validation:
+  - Summarizes all test results
+  - Determines if PR can be merged
+```
+
+## Workflow 2: GEOS Integration Testing (`test_geos_integration.yml`)
+
+### Purpose
+Tests that geosPythonPackages integrates correctly with GEOS by:
+1. Building GEOS with PyGEOSX enabled
+2. Installing Python packages into GEOS environment
+3. Verifying tools are accessible and functional
+
+### Architecture

+
+### Test Details
+
+#### Test 1: Direct setupPythonEnvironment.bash
+- **Purpose**: Validates the Python setup script works standalone
+- **What it does**:
+  - Patches script to search `/usr/local/bin/` for pip-installed tools
+  - Installs Python packages via the GEOS setup script
+  - Creates symlinks to tools in `bin_direct/`
+- **Validates**: 
+  - ✅ Python packages install correctly
+  - ✅ Scripts are findable and linkable
+  - ✅ All required tools are available
+
+**Key Implementation Detail**: The script is patched because pip installs to `/usr/local/bin/` but the setup script originally only searches:
+- `/usr/bin/`
+- `$HOME/.local/bin/`
+- `$HOME/local/bin/`
+
+#### Test 2: make geosx_python_tools
+- **Purpose**: Validates CMake target builds Python tools
+- **What it does**:
+  - Runs the `geosx_python_tools` CMake target
+  - Uses PyGEOSX virtual environment
+  - Creates tool symlinks in `bin/`
+- **Validates**:
+  - ✅ CMake integration works correctly
+  - ✅ PyGEOSX virtual environment is created
+  - ✅ Tools are accessible via CMake build system
+
+#### Test 3: make geosx_python_tools_clean
+- **Purpose**: Validates cleanup target works
+- **What it does**:
+  - Runs `geosx_python_tools_clean` target
+  - Verifies symlinks are removed
+  - Rebuilds for next test
+- **Validates**:
+  - ✅ Clean target removes symlinks
+  - ✅ Rebuild works after cleanup
+
+**Note**: This only cleans symlinks, not system-wide packages (by design).
+
+#### Test 4: make geosx_python_tools_test
+- **Purpose**: Validates Python tools test suite runs
+- **What it does**:
+  - Creates required test directory structure
+  - Symlinks test script from PyGEOSX environment
+  - Runs XML tools unit tests
+  - Cleans up test output files
+- **Tests Run**:
+  - Unit dictionary tests
+  - Units conversion tests (25 tests)
+  - Parameter regex tests (8 tests)
+  - Units regex tests (6 tests)
+  - Symbolic regex tests (13 tests)
+  - XML processor tests (4 tests)
+- **Validates**:
+  - ✅ Test infrastructure works
+  - ✅ All XML tools function correctly
+  - ✅ Cleanup process succeeds
+
+#### Test 5: XML Formatting
+- **Purpose**: Validates XML formatting functionality
+- **What it does**:
+  - Builds `geosx_python_tools` target
+  - Runs XML formatting script directly
+  - Formats all XML files in GEOS src/ and examples/
+- **Validates**:
+  - ✅ `format_xml` tool works
+  - ✅ Can process GEOS XML files
+
+**Known Issue**: The CMake target `geosx_format_all_xml_files` has a bug (depends on non-existent `geosx_xml_tools` instead of `geosx_python_tools`). We work around this by running the formatting script directly.
+
+### Environment Setup
+
+#### Container Image
+```yaml
+image: geosx/ubuntu22.04-gcc12:${GEOS_TPL_TAG}
+```
+- Ubuntu 22.04 with GCC 12
+- GEOS dependencies pre-installed
+- TPL tag dynamically extracted from GEOS
+
+#### Key Environment Variables
+```bash
+SETUPTOOLS_USE_DISTUTILS=stdlib     # Avoid setuptools/distutils conflicts
+PIP_DISABLE_PIP_VERSION_CHECK=1     # Reduce pip warnings
+PYTHONDONTWRITEBYTECODE=1           # Prevent .pyc creation
+PATH=/usr/local/bin:$PATH           # Ensure pip scripts are found
+```
+
+#### GEOS Build Configuration
+```cmake
+-DENABLE_PYGEOSX=ON                 # Enable Python integration
+-DENABLE_XML_UPDATES=OFF            # Skip XML validation (physics disabled)
+-DGEOS_ENABLE_TESTS=OFF            # Disable GEOS tests
+-DGEOS_ENABLE_*=OFF                # Disable physics solvers (faster build)
+-DGEOS_PYTHON_PACKAGES_BRANCH=...  # Use current PR branch
+```
+
+## Smart GEOS Integration Testing
+
+### When Tests Run
+
+GEOS integration tests are **automatically triggered** when changes affect:
+
+#### GEOS-Integrated Packages
+- `geos-utils/` - Core utilities used of goesPythonPackages
+- `geos-mesh/` - Mesh conversion (`convert_abaqus`, `mesh-doctor`)
+- `geos-xml-tools/` - XML preprocessing (`preprocess_xml`, `format_xml`)
+- `hdf5-wrapper/` - HDF5 I/O wrapper
+- `pygeos-tools/` - Python tools for GEOS
+- `geos-ats/` - Automated testing framework
+
+#### Critical Infrastructure Files
+- `.github/workflows/python-package.yml` - Main CI workflow
+- `.github/workflows/test_geos_integration.yml` - Integration workflow
+- `install_packages.sh` - Installation script
+
+### When Tests Are Skipped
+
+Tests are automatically skipped when changes only affect:
+
+#### Documentation
+- `docs/` - Documentation files
+- `README.md` - Repository README
+- `.readthedocs.yml` - ReadTheDocs configuration
+
+#### Non-Integrated Packages
+- `geos-geomechanics/` - Standalone geomechanics tools
+- `geos-posp/` - Post-processing utilities
+- `geos-pv/` - ParaView utilities
+- `geos-timehistory/` - Time history analysis
+- `geos-trame/` - Trame visualization
+- `geos-xml-viewer/` - XML viewing tools
+
+#### Configuration Files
+- `.gitignore`, `.gitattributes` - Git configuration
+- `.style.yapf`, `.ruff.toml`, `.mypy.ini` - Code style configs
+- `.github/workflows/doc-test.yml` - Documentation CI
+- `.github/workflows/typing-check.yml` - Type checking CI
+
+### Manual Override
+
+Add the **`test-geos-integration`** label to any PR to force GEOS integration tests to run, regardless of changed files.
+
+### Example Scenarios
+
+✅ **Tests Will Run**
+```
+Changes:
+  - geos-mesh/src/mesh_converter.py
+  - geos-xml-tools/src/preprocessor.py
+Result: GEOS integration required (affects integrated packages)
+```
+
+⊘ **Tests Will Skip**
+```
+Changes:
+  - docs/user_guide.md
+  - README.md
+  - geos-pv/src/visualizer.py
+Result: GEOS integration not required (only docs and non-integrated packages)
+```
+
+✅ **Tests Will Run (Manual)**
+```
+Changes:
+  - docs/installation.md
+Labels: test-geos-integration
+Result: GEOS integration required (manual override via label)
+```

+
+## Troubleshooting
+
+### Common Issues
+
+#### 1. Scripts Not Found
+**Error**: `(could not find where preprocess_xml is installed)`
+
+**Cause**: pip installs to `/usr/local/bin/` but setup script doesn't search there
+
+**Solution**: The CI automatically patches `setupPythonEnvironment.bash` to add `/usr/local/bin/` to search paths
+
+#### 2. Setuptools/Distutils Conflict
+**Error**: `AssertionError: /usr/lib/python3.10/distutils/core.py`
+
+**Cause**: Version mismatch between setuptools and distutils
+
+**Solution**: Set `SETUPTOOLS_USE_DISTUTILS=stdlib` environment variable (already done in CI)
+
+#### 3. XML Validation Fails
+**Error**: Schema validation errors when physics packages disabled
+
+**Cause**: Schema only includes enabled packages, but XML examples reference all packages
+
+**Solution**: Use `-DENABLE_XML_UPDATES=OFF` to disable validation (already configured)
+
+#### 4. Test 5 Make Target Fails
+**Error**: `No rule to make target 'geosx_xml_tools'`
+
+**Cause**: Bug in GEOS CMakeLists.txt - depends on non-existent target
+
+**Solution**: Run formatting script directly (workaround implemented in CI)
+
+## Contributing
+
+When adding new Python packages or modifying existing ones:
+
+1. **Update Package Lists**: If adding a package used by GEOS:
+   - Add to `GEOS_INTEGRATED_PACKAGES` in `python-package.yml`
+   - Document in this README
+
+2. **Add Tests**: Ensure your package has:
+   - Unit tests (pytest)
+   - Proper code formatting (yapf)
+   - Type hints (mypy compatible)
+
+3. **Update Documentation**:
+   - Add package docs to `docs/` directory
+   - Update main `README.md` if needed
+   - Update this CI README if CI changes
+
+4. **Test Integration**:
+   - If package integrates with GEOS, add `test-geos-integration` label to PR
+   - Verify all 5 integration tests pass
