Reference-integrity audit

Upload a bibliography and every reference is checked mechanically against Crossref, OpenAlex, arXiv, and the Pith corpus. No AI guessing which citations are real: each entry gets a deterministic classification with the resolver evidence attached, on a page you can share.

01 What the classifications mean

The audit is resolver-backed and deterministic: the same file gives the same verdicts. It claims only what the evidence supports, so "no match found" is reported as unresolved, not as fabrication.

Verified The reference's DOI or arXiv ID resolves and the metadata agrees.
Verified (fuzzy) No explicit identifier, but bibliographic search finds a confident match.
Metadata mismatch The identifier resolves, but to a different paper than the reference claims. The classic hallucinated-citation signature.
Malformed identifier A DOI-like string that is truncated or syntactically invalid.
Fabrication risk A scholarly-looking reference with no match anywhere the resolver can see.
Unresolved No match, but nothing suspicious either: books, reports, and URLs are often unindexed.

Cited arXiv papers that Pith has not yet reviewed are queued for priority review, so auditing your bibliography also grows the reviewed record.
