He usually has a large skylight in the roof, directly over the roasting equipment
judge verdicts (2)
- groundedness 1.00 pass — The claim is directly stated in the passage. The text explicitly says 'He usually has a large skylight in the roof, directly over the roasting equipment,' which perfectly matches the claimed subject-predicate-object relationship without any addition of outside knowledge or over-generalization.
- qualifier_fidelity 0.90 pass — The claim is faithful to the passage with one minor issue: the viewpoint should be 'practical coffee roaster' rather than 'author', since the passage attributes this practice to 'the practical coffee roaster' as a named source/category of practitioner, not to the author's own assertion. The quote is accurate and verbatim, stance and sentiment are correct (asserts, neutral), time qualifiers are appropriately null, and context is appropriately empty. Deduct 0.1 for viewpoint attribution.
- roasting room has original arrangement ⟨partly below street level with machinery visible from sidewalk⟩
the roasting room still has the original arrangement, partly below the street level but with the machinery in view from the sidewalk
judge verdicts (2)
- groundedness 1.00 pass — The claim is directly stated in the passage. The exact sentence 'the roasting room still has the original arrangement, partly below the street level but with the machinery in view from the sidewalk' confirms that the roasting room has the original arrangement, with the specific contextual details provided.
- qualifier_fidelity 1.00 pass — All qualifiers are faithful to the passage. The viewpoint is correctly attributed to the author (the passage presents this as factual narrative). The stance is correctly marked as 'asserts' rather than disputes or questions. The sentiment is neutral, matching the passage's matter-of-fact tone. The time is correctly null, as the passage does not specify when this arrangement exists, only that it 'still has' it. The context accurately captures the specific physical description provided. The quote is verbatim from the passage and directly supports the claim.
The practical coffee roaster locates his roasting room in the top floor of his factory building
judge verdicts (2)
- groundedness 1.00 pass — This claim is directly stated in the opening sentence of the passage: 'The practical coffee roaster locates his roasting room in the top floor of his factory building, where light and ventilation are generally best.' The claim accurately reflects the exact wording and meaning presented in the text.
- qualifier_fidelity 1.00 pass — All qualifiers are faithful to the passage. The viewpoint is correctly attributed to the author (not a named source). The stance is appropriately 'asserts' as the passage makes a declarative statement. The sentiment is neutral, matching the passage's objective tone. The time qualifiers are all null, which is correct since the passage provides no temporal scope. The context 'practical operations' accurately reflects the passage's opening reference to 'The practical coffee roaster.' The quote is verbatim and directly supports the claim.
where light and ventilation are generally best
judge verdicts (2)
- groundedness 1.00 pass — The claim is directly stated in the passage. The first sentence explicitly says that the practical coffee roaster 'locates his roasting room in the top floor of his factory building, where light and ventilation are generally best,' which directly supports the claim that top floor location provides good light and ventilation for the roasting room.
- qualifier_fidelity 0.90 pass — The claim is largely faithful to the passage. The viewpoint is correctly identified as 'author' (the passage presents this as general knowledge about coffee roasting practice, not attributed to a named source). The stance 'asserts' and sentiment 'positive' are appropriate. Time qualifiers are correctly null as the passage provides no temporal scope. Context is appropriately empty. The quote is verbatim and supports the claim. Minor deduction (0.1): The claim slightly simplifies the passage's causal structure—the passage states the top floor location "makes it possible" to achieve these benefits and notes it "locates" there, but the quote fragment given ('where light and ventilation are generally best') is presented as an observation rather than a benefit resulting from deliberate placement. This is a very minor issue of nuance rather than a substantive qualifier error.
which is usually hung to the ceiling of the roasting room
judge verdicts (2)
- groundedness 1.00 pass — The claim is directly stated in the passage: 'The coffee, passing up the riser pipe, is delivered into a large "stoner hopper" which is usually hung to the ceiling of the roasting room.' The subject, predicate, and object all match exactly with the source text.
- qualifier_fidelity 1.00 pass — All qualifiers are faithful to the passage. The viewpoint is correctly attributed to the author (the passage itself presents this as factual description). The stance is appropriately 'asserts' as the passage states this as fact. Sentiment is neutral, matching the technical, informative tone of the passage. Time qualifiers are correctly null as the passage provides no temporal scope. Context is empty as appropriate since the passage does not restrict the claim to a specific sense or period. The quote appears verbatim in the passage and directly supports the claim.
