Ittel's glass sphere, Lyons, 1874
judge verdicts (2)
- groundedness 0.70 pass — The passage directly states 'Ittel's glass sphere, Lyons, 1874' in the context of French coffee-roaster improvements. While the exact verb 'produced' is not explicitly used, the listing format clearly attributes this invention to Ittel in that year, which constitutes a stated claim with minor rewording from the original phrasing.
- qualifier_fidelity 1.00 pass — All qualifiers are faithful to the passage. The viewpoint correctly attributes the claim to the author (not to a named source); the stance appropriately uses 'asserts' for a straightforward factual statement; sentiment is neutral, matching the passage's tone; the time qualifiers correctly reflect 1874 with valid_from set to 1874 and valid_to as null (no end date specified); context is appropriately empty as the passage provides no specific sense restriction; and the quote appears verbatim in the passage and directly supports the claim about Ittel producing a glass sphere in Lyons in 1874.
