judge verdicts (2)
- groundedness 1.00 pass — The claim is directly supported by the passage, which explicitly states 'Beeston Tupholme, of London, was granted an English patent in 1887, on a direct-flame gas roaster.' All key elements (subject, predicate, object, and time) match the source text exactly.
- qualifier_fidelity 1.00 pass — All qualifiers are faithful to the passage. The viewpoint is correctly attributed to the author (the passage itself makes the assertion, not a named source). The stance is 'asserts' which matches the factual presentation in the passage. The sentiment is neutral, appropriate for a factual historical statement. The time qualifier correctly specifies 1887 with valid_from matching and valid_to as null (no end date given). The context is appropriately empty as the passage does not restrict this to a particular sense or role. The quote is verbatim and directly supports the claim.

- groundedness 1.00 pass — The claim is directly stated in the passage: 'Beeston Tupholme, of London, was granted an English patent in 1887, on a direct-flame gas roaster which he assigned to Joseph Baker & Sons.' The subject, predicate, and object are all explicitly mentioned with no rewording required.
- qualifier_fidelity 0.90 pass — The claim is largely faithful to the passage. The viewpoint is correctly set to 'author' as the passage does not attribute this statement to a named source but presents it as factual narrative. The stance and sentiment are both correct. The quote matches verbatim from the passage. However, there is a minor issue with the time qualifier: the passage specifies that Tupholme 'was granted an English patent in 1887,' which provides a temporal context for when the assignment occurred. The claim sets 'when' to null, but the passage does give a specific date (1887) that should arguably be captured. This is a minor qualifier fidelity issue, but the claim's core structure remains faithful since the assignment itself is intrinsically linked to the 1887 patent event described in the passage.
