judge verdicts (2)
- groundedness 1.00 pass — The claim is directly stated in the passage: 'James R. Webb established the coffee roasting business of James R. Webb & Son in 1833.' All elements (subject, predicate, object, and date) are explicitly supported by 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 makes an unattributed assertion). The stance is 'asserts' which matches the declarative framing. The sentiment is neutral, which is appropriate for the factual statement. The time qualifiers (when: 1833, valid_from: 1833, valid_to: null) accurately reflect the temporal information in the passage. The context is empty, which is correct as the passage does not restrict the claim to a particular sense or role. The quote is verbatim from the passage and directly supports the claim.
