Vienna coffee pot, 1830
judge verdicts (2)
- groundedness 1.00 pass — The claim is directly stated in the passage. The line 'Vienna coffee pot, 1830' explicitly indicates that a Vienna coffee pot dates from 1830, with no rewording or interpretation needed.
- qualifier_fidelity 0.90 pass — All qualifiers are faithful to the passage. The viewpoint, stance, sentiment, time, and context all correctly match the passage. The quote appears verbatim. Minor deduction (0.1) only because the time object uses specific valid_from/valid_to dates of exactly 1830, when the passage only provides "1830" without specifying whether this is a precise year or an approximate dating—however, this is a very minor issue and the claim remains fundamentally faithful.
