  "status": "partially_source_checked",
  "scope": "Claim-level traceability review of the article and matching dataset object. Checked: the wording and sequence of the demon’s hypothetical in The Gay Science §341; the test-of-affirmation interpretation; published recurrence formulations in Beyond Good and Evil §56 and Thus Spoke Zarathustra, Part III, “The Vision and the Enigma”; the article’s distinctions among existential, cosmological, and ethical/affirmative readings; its use of amor fati; its distinction from Poincaré recurrence; and its claims about the role of notebooks and scholarly disagreement. The status is conservative because the cited unpublished notebook fragment was not directly accessible and the review does not adjudicate competing interpretations or constitute exhaustive literature review, proof that recurrence is true, consensus, or expert review.",

  "summary": "The article’s original existential-only framing and its broad statement that Nietzsche does not say life is worth repeating needed qualification. The accessed primary texts support a distinction between the hypothetical challenge in The Gay Science §341 and more affirmative or cosmological-sounding formulations in Beyond Good and Evil §56 and Zarathustra, Part III. The article was revised to describe those formulations, distinguish interpretive readings without treating them as settled or exclusive, and state the notebook-access gap. R. Lanier Anderson’s SEP entry emphasizes §341’s test of affirmation; Neil Sinhababu (2024) argues for cosmological significance in notebook material and reads Zarathustra as fiction foregrounding response. The original notebook passage itself could not be read; status is therefore partially_source_checked. The dataset was synchronized after the audit to match the article’s six Further Reading URLs and 2026-11-01 verification date. The status remains partial because the cited unpublished notebook fragment was not directly accessed.",
