judge verdicts (2)
- groundedness 1.00 pass — The claim is directly stated in the passage. The sentence 'The famous Caffe Florian was opened in Venice by Floriono Francesconi in 1720' explicitly confirms all elements of the claim: the subject (Caffe Florian), predicate (opened in Venice by), object (Floriono Francesconi), and time (1720).
- qualifier_fidelity 0.90 pass — Nearly all qualifiers are faithful to the passage. The quote is verbatim and supports the claim. The time (1720) and temporal scope (valid_from: 1720, valid_to: null) are correct. The context is appropriately empty as the passage provides no restricting sense or role. However, the viewpoint should be null rather than 'author' - the passage itself states this as fact without attributing it to a named source, so no explicit viewpoint attribution is needed. The stance 'asserts' and sentiment 'positive' (reflected in 'famous') are appropriate.

judge verdicts (2)
- groundedness 1.00 pass — The claim is directly stated in the passage: '1720--Caffe Florian is opened in Venice by Floriono Francesconi.' All components (subject, predicate, object, and time) are explicitly supported without rewording or generalization required.
- qualifier_fidelity 0.90 pass — The claim is largely faithful to the passage. The viewpoint, stance, sentiment, time, and quote are all accurate and well-supported. However, the passage attributes the opening to 'Floriono Francesconi' by name, and the claim does not include this named source in its qualifiers. While this is a minor omission rather than an active error, strict fidelity would capture that the opening was performed by this specific person. The context field is appropriately empty as the passage provides no restricting context.

judge verdicts (2)
- groundedness 1.00 pass — The claim is directly stated in the passage: '1720--Caffe Florian is opened in Venice by Floriono Francesconi.' All elements (subject, predicate, object, time, and context) match exactly what is written.
- qualifier_fidelity 0.85 pass — Minor issue with viewpoint qualifier: the claim uses "author" as viewpoint, but the passage itself makes the assertion directly (it is not attributed to a named source). The viewpoint should be "passage" or similar neutral indicator rather than "author". All other qualifiers are faithful: stance is correctly "asserts", sentiment is neutral, time (1720) matches, context (Venice) is accurate, and the quote matches verbatim from the passage.
