- ✅ Library API: 20/22 tests passing (91%)

**Phase 3.3: Core Implementation (95% Complete)**
- ✅ Core models and data structures (mosaicx/core/models.py, exceptions.py)
- ✅ Report extractor engine (mosaicx/extractor.py) 
- ✅ Schema builder system (mosaicx/schema.py)
- ✅ CLI interface complete (mosaicx/cli/main.py)
- ✅ Utility functions (mosaicx/utils.py)
- ✅ Package exports (mosaicx/__init__.py)

### 🔥 MAJOR TECHNOLOGY UPGRADES IMPLEMENTED
1. **uv Package Manager**: 25x faster than pip, superior dependency management
2. **Docling 2.51.0**: Advanced PDF processing with ML models, replaced PyPDF2/pdfplumber  
3. **Dual Licensing**: AGPL-3.0 + commercial licensing via Zenta GmbH
4. **Test-Driven Development**: Comprehensive contract tests written before implementation
