  "summary": "All central numeric claims in the article trace to the supplied analysis and deterministic comparison facts; all referenced artifacts (weather-model-overall, weather-model-by-position, weekly-weather-projection-error) appear in the SHA-256 inventory with matching hashes; source URLs are present in the claim ledger and provenance; license and attribution language (NOAA public-domain US Government work; nflverse CC BY 4.0 with contributor attribution) matches the approved provenance record; and the article preserves the registered caveats about population-level estimates and position-level associations.",
