  "scope": "Claim-level traceability review of the article and matching dataset entry. Checked the date/attribution framing; B12 and the familiar cannot-step-twice report; their ancient transmission through Plato, Eusebius/Cleanthes, Aristotle/Cratylus and Plutarch; the competing scholarly readings of B12 and B91; and whether the modern comparisons are clearly marked as educational framing. The status records traceability, not a settled reconstruction of Heraclitus’s view, exhaustive fragment scholarship, or expert review.",
  "summary": "The article now distinguishes the transmitted B12 wording from Plato’s Cratylus report and does not present the famous cannot-step-twice sentence as a secure verbatim translation of B12. It identifies the disagreement between Daniel W. Graham’s SEP account, which treats B12 as the likely genuine river fragment and B91 as a paraphrase, and Leonardo Taran’s argument that B91 may preserve a separate saying. Ancient witnesses and the two secondary readings were consulted; the article leaves authenticity and interpretation disputed rather than deciding them. Modern analogies are explicitly labeled as teaching comparisons.",
