Blanke's cloth (1909)
judge verdicts (2)
- groundedness 0.70 pass — The claim is directly supported by the passage, which lists 'Blanke's cloth (1909), 651' in the filtration devices index. The date 1909 is explicitly stated, though the passage uses parenthetical notation rather than the word 'patented,' which is a minor rewording acceptable for an index entry.
- qualifier_fidelity 1.00 pass — All qualifiers are faithful to the passage. The quote 'Blanke's cloth (1909)' appears verbatim in the filtration devices index. The viewpoint is correctly set to 'author' as the passage does not attribute this information to a named source. The stance 'asserts' is appropriate as the passage simply lists the device with its date. The sentiment 'neutral' matches the factual, indexical nature of the passage. The time qualifier correctly reflects 1909 as stated in the passage, with valid_from set to 1909 and valid_to as null, which is appropriate given the passage provides only a single date. The context is appropriately empty as the passage provides no additional contextual restrictions beyond the device name and date.
