- qualifier_fidelity 1.00 pass — All qualifiers are faithful to the passage. The viewpoint is correctly attributed to the author (passage itself, not a named source). The stance 'asserts' matches the declarative framing. Sentiment is neutral, which is appropriate for a factual historical statement. The time '1880' matches the passage exactly. The context 'Ceylon' is correctly specified as stated in the passage. The quote is verbatim and directly supports the claim. No deductions warranted.
