judge verdicts (2)
- groundedness 1.00 pass — The claim is directly stated in the passage. The text explicitly states 'at the close of the convention it was announced that the membership was then seventy-one firms in cities as far east as Virginia and as far west as Kansas City,' which matches the subject, predicate, object, and time frame specified in the claim.
- qualifier_fidelity 0.90 pass — Qualifier fidelity is strong. Viewpoint, stance, and sentiment are all correct - the author reports this fact neutrally without attribution to a specific named source. The time qualifier is appropriate: "when" correctly set to "November 1911" with valid_from matching the convention date (November 16-17, 1911), and valid_to correctly null since the passage gives no end date. Context appropriately specifies "at close of first convention" which matches the passage's temporal framing. Quote is verbatim and supports the claim. Minor note: valid_from uses November 17 (the closing date) which is slightly more precise than "November 1911," but this represents an acceptable normalization rather than an infidelity.
