Retired. This entry was not a citation. Our extractor stored an inline prose definition from the article as though it were a bibliographic record: the title names a concept rather than a published work, and the citation text names no work at all. The page is kept because links to it still resolve, but it is withdrawn from the reference list. This entry is kept so the citations that pointed at it still resolve, and so the correction is visible rather than silent.
