judge verdicts (2)
- groundedness 1.00 pass — The claim is directly and fully supported by the passage. The exact sentence states that 'In 1882, a German patent was granted to Emil Newstadt, of Berlin, on one of the earliest coffee-extract machines,' which matches all elements of the claim including subject, predicate, object, and time.
- qualifier_fidelity 1.00 pass — All qualifiers are faithful to the passage. The viewpoint is correctly attributed to the author (the passage itself makes the assertion), the stance is correctly marked as 'asserts', sentiment is neutral, the time (1882) matches the passage, context is appropriately empty, and the quote appears verbatim and supports the claim.

- groundedness 1.00 pass — The claim is directly stated in the passage. The exact quote 'A German patent is granted to Emil Newstadt, Berlin, on one of the earliest coffee-extract-making machines' appears in the 1882 entry, fully supporting all elements of the claim including the subject, predicate, object, time, and context.
- qualifier_fidelity 1.00 pass — All qualifiers are faithful to the passage. The viewpoint is correctly attributed to the author (the passage does not name a specific source for this claim). The stance 'asserts' is appropriate as the passage states this as fact. The sentiment is neutral, matching the passage's neutral tone. The time qualifier correctly specifies 1882 with no end date (valid_to: null) as the passage provides no temporal restriction beyond the grant year. The context 'German patent' accurately reflects the passage's specification. The quote is verbatim from the passage and directly supports the claim.
