pdf-to-md

Turn a PDF into Markdown. The right path depends on the document type and whether external document submission has been approved:

• Scientific paper → produce the canonical paper-to-md bundle (Markdown + section_audit.json + article.json) so it can feed csag-extraction. Use LiteParse v2 locally unless the user explicitly approves the remote OCR API.
• Any other PDF (reports, slides, letters, forms) → just convert to Markdown with LiteParse v2 for a fast, local, no-key result. Stop there.

LiteParse must be v2 (run-llama/liteparse, the Rust rewrite with the LiteParse Python API and lit CLI). LiteParse v1 is a different, unsupported API. liteparse_to_md.py pins liteparse>=2,<3 and refuses to run on anything else, so uv run always provisions the right per-platform v2 binary inside the wheel — nothing to vendor or compile, and no API key. OCR is on by default (bundled Tesseract).
