judge verdicts (2)
- groundedness 1.00 pass — The claim is directly stated in the passage. The exact quote confirms that Tupholme's English machine was installed by F.T. Holmes at the Potter-Parlin Co. plant in New York in 1893, with no rewording or interpretation needed.
- qualifier_fidelity 1.00 pass — All qualifiers are faithful to the passage. The viewpoint is correctly identified as 'author' (the passage presents this as a historical fact without attribution to a named source). The stance 'asserts' is appropriate for the factual presentation. Sentiment 'neutral' matches the documentary tone. The time qualifier '1893' matches the passage date. The context 'plant of Potter-Parlin Co., New York' is accurate. The quote appears verbatim and fully supports the claim.
