  "summary": "All central numeric claims (1,258 games, 98.1% coverage, 184 of 2,516 forecast requests, 24/6-hour cutoffs, 2024 observed-weather lag vs. 2025 football inputs) trace to the supplied analysis and claim ledger. The referenced figure artifact (weather-evidence-architecture) and its SHA-256 appear in the inventory; the table artifact is defined in publication-assets.json. All three sources have URLs, approved rights, and licenses consistent with the provenance record (NOAA public domain; nflverse CC BY 4.0). Caveats about the withheld challenger and prediction-ineligible observations are preserved.",
