When the roast begins to snap, the flame is turned lower to allow the beans to cook through evenly
judge verdicts (2)
- groundedness 1.00 pass — The claim is directly stated in the passage. The exact phrase 'When the roast begins to snap, the flame is turned lower' appears verbatim, confirming the subject-predicate-object relationship without any rewording or extrapolation required.
- qualifier_fidelity 1.00 pass — All qualifiers are faithful to the passage. The viewpoint is appropriately 'author' since the passage itself makes this procedural statement without attributing it to a named source. The stance 'asserts' correctly reflects the passage's factual description. The sentiment 'neutral' matches the technical, instructional tone. The time qualifier correctly identifies the temporal scope as 'when the roast begins to snap' with no specific calendar dates (valid_from and valid_to are null as appropriate). The context 'when roast begins to snap' appropriately captures the conditional restriction. The quote is verbatim from the passage and directly supports the claim.
when nearly done, it is almost extinguished
judge verdicts (2)
- groundedness 1.00 pass — This claim is directly stated in the passage. The text explicitly says 'when nearly done, it is almost extinguished,' referring to the flame during the coffee roasting process, which matches the claim's subject, predicate, and temporal context exactly.
- qualifier_fidelity 1.00 pass — All qualifiers are faithful to the passage. The viewpoint is correctly attributed to the author (the passage describes the process without naming a specific source). The stance is appropriately 'asserts' as the passage states this as fact about the roasting procedure. The sentiment is neutral, matching the technical, descriptive tone of the passage. The time qualifier 'when nearly done' accurately reflects the temporal scope stated in the passage. The context 'when nearly done' properly restricts the claim to that specific stage of the roasting process. The quote 'when nearly done, it is almost extinguished' appears verbatim in the passage and directly supports the claim.
heat slowly over a flame until swelling ceases
judge verdicts (2)
- groundedness 1.00 pass — The claim is directly supported by the passage. The text explicitly states 'heat slowly over a flame until swelling ceases,' which directly confirms that the sample is heated over a flame with the specified condition of until swelling ceases.
- qualifier_fidelity 0.90 pass — The claim is faithful to the passage with one minor note: the viewpoint is correctly identified as 'author' (the passage presents procedural instructions without attribution to a named source). The stance, sentiment, time, and context qualifiers are all accurate. The quote is verbatim and supports the claim. The only minor consideration is that the claim's object is 'flame' while the quote specifies 'a flame' - this is a negligible difference in indefinite article usage that does not affect fidelity.
the flame was spread over a large area to avoid scorching and to insure a more thorough and uniform roast
judge verdicts (2)
- groundedness 1.00 pass — The claim is directly stated in the passage. The text explicitly describes Ellis M. Potter's 1899 patent as featuring 'an improved direct-flame gas roaster in which the flame was spread over a large area to avoid scorching and to insure a more thorough and uniform roast,' matching the subject, predicate, and object of the claim exactly.
- qualifier_fidelity 0.90 pass — Nearly all qualifiers are faithful. The viewpoint is correctly attributed to the author (the passage itself presents this as factual information about Potter's patent, not attributed to a named source). Stance, sentiment, time (1899), and quote are all accurate and faithful to the passage. The context is appropriately empty since the passage does not restrict the claim to a particular sense. Minor deduction only because the claim's predicate structure slightly reorders the passage's phrasing, though the meaning is preserved and the quote accurately reflects the source material.
