- qualifier_fidelity 1.00 pass — All qualifiers are faithful to the passage. The viewpoint is correctly attributed to the author (the passage itself makes this assertion, not a named source). The stance is accurately characterized as 'asserts' - the passage states this as fact. The sentiment is appropriately neutral, reflecting the informative tone.
