  "summary": "Attempted falsification of the headline claim (weather reduced weekly PPR projection error) failed. The overall improvement (4.662 to 4.635 MAE, +0.568%, CI +0.328% to +0.810%) is internally consistent across the analysis, claim ledger, tables, and article text. Season-level and position-level numbers all reconcile with the underlying data. Headline and figure/table titles remain standalone after removing series label, dek, and axes: the title names the subject (NFL weather), outcome (reduced weekly fantasy projection error), and timeframe (2019\u20132024); the figure alt text and table captions do the same. All percentages are defined in-line (MAE in PPR points, improvement vs. champion, positive change meaning challenger worse). Disclosed limitations (population-level estimate, RB regression, near-zero 2024 gap, no per-decision or causal claims) are appropriately scoped and prevent the most likely over-applications by fantasy readers. Freshness requirement is met (data through 2024, minimum 2024).",

      "evidence": "The 2024 window gap is -0.0026 MAE points, effectively a tie, yet the article counts it as a 'win' in 'all six future-season windows.'

      "evidence": "The RB position regressed (+0.24% MAE) and QB/WR drove gains. The article discloses this and frames the result as population-level, explicitly disclaiming per-player or per-decision applicability, which blocks the most likely reader over-application (bench/start decisions based on weather for a specific player).",
