  "summary": "All central numeric claims in the article map to the supplied analysis: combined points (49.1 vs 48.8, +2.5, CI -3.5 to +8.4, Holm p 0.536), pass EPA per dropback (0.080 vs 0.044, +0.041, CI -0.031 to +0.113, Holm p 0.536), field-goal accuracy (92.4% vs 85.7%, +9.6 pts, CI +3.6 to +15.6, Holm p 0.007), and kicker fantasy points (18.7 vs 17.6, +3.0, CI +0.5 to +5.5, Holm p 0.060) each match the analysis effects and the claim ledger. Sample counts (41 condition, 292 control, 333 comparable, 39/289 for field-goal accuracy) match the sample block. Named artifacts weather-open-closed-roof-table and weather-open-closed-roof-effects appear in the publication assets and the figure hash matches the SHA-256 inventory. The nflverse source URL is present in provenance and in every claim ledger entry, license CC BY 4.0 with attribution language matches the provenance record, and the article preserves caveats on retrospective association, non-causality, small open-roof sample, and the postgame roof state not being a pregame forecast input.",

      "evidence": "analysis.source_applicability shows football and roof data through 2025 and observed weather data through 2024, but observed weather is not an input to any outcome; the article discloses data through the 2025 season and makes no current-player claims.",
      "recommendation": "No change required; the article accurately discloses the data-through date and the weather data lag is immaterial because weather observations are not used in this study."
