  "scope": "Claim-level audit of article sections 1–10 and associated publication/source claims: scenario and fatalist inference; Aristotle’s response and contested attribution; bivalence, excluded middle, and the summaries of three-valued/truth-gap, branching-time, supervaluationist, Ockhamist, and Peircean approaches; contemporary extensions; editorial framing. Checked against the complete relevant passage of De Interpretatione 9, the cited SEP entry's relevant sections, and a full-text scholarly discussion of interpretive disagreement. This status concerns evidence traceability, not philosophical soundness, consensus, exhaustive literature coverage, or expert review.",
  "summary": "The primary chapter, relevant SEP sections, and a scholarly analysis support the article’s account of Aristotle’s fatalist inference, response, and later semantic frameworks. The Ockham passage now specifies that future truth is unknowable to humans but known by God, as SEP §5.1 states. Targeted independent review found no remaining material issue; article and dataset Further Reading URLs match.",
