check_retraction

Active

declared in 0.1.0

Check whether a paper (by DOI) has been retracted, according to Crossref/Retraction Watch (keyless). Returns retracted:true/false with the evidence (title marker + retraction-notice link). NOTE: 'not retracted' means no retraction is on record — coverage depends on the publisher, so it is not definitive proof the paper is clean.
