    • qualifier_fidelity 1.00 pass — All qualifiers are faithful to the passage. The viewpoint is correctly attributed to the author (the passage itself presents this information without attribution to a named source). The stance is 'asserts' which matches the declarative manner of the passage. The sentiment is neutral, which is appropriate for a factual statement about commercial activity. The time qualifier correctly specifies 'before 1912' matching the passage's explicit temporal reference, with valid_to normalized to 1912 and valid_from as null (no start date given). The context is appropriately empty as no specific sense or restriction is applied. The quote is verbatim from the passage and directly supports the claim.
