Table data format fixes (ocr_to_unified_converter.py): - Fix ElementType string conversion using value-based lookup - Add content-based HTML table detection (reclassify TEXT to TABLE) - Use BeautifulSoup for robust HTML table parsing - Generate TableData with fully populated cells arrays Image cropping for OCR track (pp_structure_enhanced.py): - Add _crop_and_save_image method for extracting image regions - Pass source_image_path to _process_parsing_res_list - Return relative filename (not full path) for saved_path - Consistent with Direct Track image saving pattern Also includes: - Add beautifulsoup4 to requirements.txt - Add architecture overview documentation - Archive fix-ocr-track-table-data-format proposal (22/24 tasks) Known issues: OCR track images are restored but still have quality issues that will be addressed in a follow-up proposal. 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude <noreply@anthropic.com>
