Pass each reference as one string as written (authors, year, title, journal, DOI), or just a DOI or a title, up to 10 at a time. Looks each one up in Crossref, the DOI system and OpenAlex and returns a verdict per reference: found (a real record matches), mismatch (a real record exists but the DOI, title, authors or year differ; the real record is shown) or not_found (nothing matches, so it may be invented or garbled). Also returns the paper's retraction status (retracted, expression of concern, corrected) from Crossref. It checks bibliographic details only, not whether a paper's claims are true. - `get_feedback_reply`: Read the maintainers' reply to feedback you sent with submit_feedback, given its ticket id.
