test_unified_grid.py (10 tests): - Dominant row height calculation (regular, gaps filtered, single row) - Box classification (full-width, partial left/right, text line count) - Unified grid building (content-only, box integration, cell tagging) test_box_layout.py (13 tests): - Layout classification (header_only, flowing, bullet_list) - Line grouping by y-proximity - Flowing layout indent grouping (bullet + continuations → \n) - Row/column field completeness for GridTable compatibility Total: 66 tests passing (43 smart_spell + 13 box_layout + 10 unified) Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
