  "summary": "The evidence bundle supports the article's claims. Row counts reconcile exactly (position strata sum to 20,700; season strata sum to 20,700; challenger and champion share identical denominators per stratum). The headline improvement (+0.568%, 95% CI +0.328% to +0.810%) matches the analysis JSON, and the game-cluster bootstrap (916 clusters, 4,000 draws) is an appropriate uncertainty method given shared within-game weather. Temporal validation, cutoff-safe forecast availability, and the locked estimand are consistently described across the registration, analysis, and article. No leakage, invalid outcome construction, fabricated evidence, or irreproducibility findings. The article appropriately discloses the RB regression (+0.24%), the near-zero 2024 gap, and the population-level scope of the estimate.",

      "recommendation": "The data run through 2024 while the freshness mode expects the latest completed season (2025 as of the run date). This satisfies the stated minimum but leaves the most recent completed season untested; the article's scope limitation ('results cover 2019 through 2024') should remain visible, and readers should not treat this as validated on 2025-season data."

      "evidence": "analysis.json by_position and by_season sub-analyses; overall_improvement_pct_ci_95 excludes zero but no per-window or per-position intervals are reported",
      "recommendation": "The six season wins and position-level results are reported without uncertainty intervals; the article correctly frames them as point-estimate descriptions and does not claim statistical significance for them. Keep this framing \u2014 do not upgrade sub-analyses to 'significant' claims."

      "recommendation": "The population is conditioned on weather availability, which is disclosed. This is a survivor/eligibility conditioning on the challenger's own feature; the article's 'eligible player-weeks' language keeps this visible and should be retained."
