judge verdicts (2)
- groundedness 1.00 pass — The claim is directly stated in the passage with the exact same wording in the final sentence. All elements (Robert Burns, United States patent, coffee-granulating mill, 1914) are explicitly confirmed.
- qualifier_fidelity 1.00 pass — All qualifiers are faithful to the passage. The viewpoint is correctly identified as 'author' (the passage itself states the fact, not a named source). The stance 'asserts' is appropriate for a straightforward factual statement. The sentiment 'neutral' matches the passage's neutral tone. The time qualifiers (when: 1914, valid_from: 1914, valid_to: null) correctly reflect the passage's temporal information. The context is appropriately empty as the passage provides no contextual restrictions. The quote is verbatim from the passage and directly supports the claim.
