    judge verdicts (2)
    • groundedness 1.00 pass — The claim is directly stated in the passage: 'about the year 1850 a new five-story building, costing some $60,000, succeeded it [the original Tontine coffee house].' The subject, predicate, object, and temporal information all match the exact wording of 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 presents this as historical narrative without attributing it to a named source). The stance is properly marked as 'asserts' since the passage states this as fact. The sentiment is neutral, matching the passage's tone. The time qualifier correctly captures 'about the year 1850' with appropriate normalization to 1850 and null for valid_to since no end date is specified. The context is appropriately empty as the passage does not restrict this claim to a particular sense or role. The quote is verbatim and directly supports the claim that the new Tontine structure succeeded the original coffee house around 1850.

    judge verdicts (4)
    • groundedness 0.70 pass — The claim is directly supported by the passage, which explicitly states 'This new Tontine structure is said to have been the first real office building in New York City.' The quote matches the claim, though the passage uses 'is said to have been' indicating reported information rather than absolute fact, which is a minor hedging difference.
    • qualifier_fidelity 0.60 fail — The viewpoint is incorrect: the passage explicitly uses 'is said to have been' which indicates an unattributed/reported claim, not a direct authorial assertion. The claim should use viewpoint 'reported' or similar qualifier reflecting this hedged attribution, not 'author' with stance 'asserts'. The stance should reflect the tentative nature ('is said to have been') rather than a definitive assertion. Additionally, the time qualifier is problematic: the passage states 'about the year 1850' which is approximate, but the claim normalizes this to exact dates (valid_from: 1850, valid_to: null), losing the temporal imprecision indicated by 'about'.
    • groundedness 1.00 pass — The claim is directly stated in the passage with the exact phrase 'This new Tontine structure is said to have been the first real office building in New York City,' matching all key elements including the subject, predicate, object, temporal context (about 1850), and the reported/questioning perspective indicated by 'is said to have been.'
    • qualifier_fidelity 0.90 pass — The claim is largely faithful to the passage. The quote is verbatim and accurate. The viewpoint is correctly marked as 'reported' given the 'is said to have been' phrasing. The time qualifier 'about the year 1850' matches the passage. However, there is a minor issue: the stance is marked as 'questions' but the passage uses 'is said to have been,' which expresses reported uncertainty rather than active questioning or disputation. The stance should be 'reported' or 'uncertain' rather than 'questions,' as the passage is presenting a claim made by others, not questioning its validity. The sentiment is appropriately neutral, and the context is correctly left empty as the passage provides none.
