- Add kg_ocr/export/markdown_exporter.py with export_markdown()
- Cluster entity co-occurrences using Louvain community detection
- Wire -f markdown into `ocr-pipeline kg export` CLI command with KG_REPORT.md default
- Add unit and CLI tests in tests/test_graph.py
- Document markdown export in README.md
- Untrack pycache binaries and ignore graphify-out and KG_REPORT.md
- Delete notebooks/ (personal scratch artifacts; gitignored)
- Move nbformat to --extra migrate; lazy imports in migrate.py and
cli.py so base CLI loads without it
- Restore langchain-text-splitters in core (chunking dependency)
