  • qualifier_fidelity 1.00 pass — All qualifiers are faithful to the passage. The viewpoint is correctly attributed to the author (the passage describes the device in its own voice). The stance 'asserts' accurately reflects how the passage presents this information. The sentiment is neutral, matching the factual tone.
