  "scope": "Claim-level traceability audit of the Gavagai article and its matching data/experiments.json record. Checked the original radical-translation setup; publication/name/date attribution; the Gavagai/Rabbit stimulus-meaning example and alternatives for term reference; the distinction between inscrutability of reference and broader indeterminacy of translation; communication/translation qualifications; the named scholarly objection/reply; article framing; and reference alignment after parent-side dataset reconciliation. The status records source traceability, not that Quine’s argument succeeds, that an interpretation is consensus, or that the work received expert review.",
  "summary": "The article was revised against directly read passages in Quine’s Word and Object, Chapter 2, §§7, 12, and 15–16, and relevant passages in Quine’s 1970 paper, especially pp. 181–82. These sources support the setup, tentative “Rabbit” translation, term-reference alternatives, analytical-hypothesis qualifications, and Quine’s later clarification that Gavagai is at best an example of inscrutability of terms—not by itself the indeterminacy of sentence translation. The Fall 2025 SEP Quine entry supports broader context, communication qualifications, and a named objection/reply; the archived SEP Reference entry directly discusses Gavagai and rabbit-part/stage alternatives. The article and dataset were reconciled: the record now links the primary passages and the archived Reference entry, and the SEP Quine citation is no longer described as containing the exact Gavagai example. Relevant Chapter 2 passages were read in a hosted reproduction; the complete book and title page were not consulted.",
