Verdicts

retracted: Crossref reports a retraction, withdrawal or removal (or the title is marked RETRACTED/WITHDRAWN).
expression_of_concern: an expression of concern is reported.
corrected: a correction, erratum, addendum or similar is reported.
ok: nothing of the above is reported by Crossref. This means "no signal", not a guarantee that the paper is sound.
not_found: the DOI is not in Crossref (it may be registered with another agency, e.g. DataCite).
unknown: the source failed (reason in error).
