Verify every cited reference of a LaTeX project (or a .bib file) against real scholarly records, and check citation keys and the bibliography.

Returns a summary (error/warning counts, one verdict per reference, whether the run was complete) and the findings, most severe first, max_findings at a time; call again with offset=next_offset for more. complete: false means a source was unavailable, so the paper cannot be declared clean yet. offline: true answers from the local cache only. The first run of a paper may take a minute or two (progress is reported while the references are searched); later runs are served from the cache.

Use this first, on the whole paper. Use preflight_explain to understand a finding, preflight_bib_fix to get the corrections as a diff, and preflight_bib_lookup to get a single entry.

Explain a paper-preflight rule (for example REF003 or CIT001): what it detects, its default severity, the message template and whether a fix can be applied safely. Use it when a finding from preflight_check is unclear; it does not look at the paper.

Get a BibTeX entry for a DOI, an arXiv ID or a title, built from the registry record instead of written from memory. Give identifier, or title (with author and year when you know them).

status is "found" (use bibtex as is), "ambiguous" (several works match: pick from candidates with the user, or retry with author/year), "not_found" (ask the user for the source; do not invent one) or "unavailable" (a source did not answer; retry later). A published preprint comes back as its published version with the eprint kept; status_flags lists notices such as "retracted".

Use it when adding or replacing one entry; to check a whole bibliography use preflight_check.

Propose edits to the .bib files, taken from the verified records, as a unified diff. Nothing is written: apply the diff with your own editing tools.

level="safe" only fixes identifiers written so that links break and adds DOIs the registry has; level="unsafe" also rewrites authors, title, year and venue from the record, removes identifiers that point to another work and cites a preprint as its published version (keeping the eprint). Show unsafe diffs to the user before applying them. References nobody could find are never "fixed".

Use it after preflight_check has reported errors or warnings in the bibliography.

For each sentence of the paper that cites key: the claim it makes and the passages of the cited work ranked best for that claim, for you to judge whether the work supports it. The first call downloads the work's text (its arXiv source, an open-access full text or PDF, or else its abstract) into the local cache.

Judge each claim conservatively. Say "confirmed" only when a passage states it (quote the passage word for word) or, for a citation set right after a name such as "Adam \cite{...}", when name_in_title is true. Otherwise say "could not confirm", with the reason: no text, only the abstract, or no passage says it. Never call a citation wrong or invented on this evidence: the text may say it in other words, or be only an abstract. evidence.level is "full_text", "abstract" or "none".

Use it only after preflight_check has verified that the work exists; it answers whether a real work supports a sentence, not whether the reference is correct.
