   "claim": "Was the whole year exceptionally dry near Drogheda?",

  },
  {
   "claim": "Can the records reveal what Markey changed in the sky?",
   "result": "No. The gallery documents an older compositional model and political additions. Rainfall without a painted day, verified sky description or making evidence cannot identify an altered sky."

 "limits": [
  "Only nonnegative amounts with indicator 0 (OK) or 4 (trace); a complete calendar window is required for every total and rank.",
  "Indicator 4 is an observed trace (<0.05 mm) encoded as zero; it is not an observed absence of rain.",
  "Estimated values, accumulations, unavailable entries and absent dates remain excluded, with raw token and indicator retained. No infilling or redistribution.",
  "Competition rank: one plus the number of strictly smaller accepted totals; ties and comparison counts are retained. Months use their own complete-year sets.",
  "Provider dates are retained. A morning gauge total is not a midnight-to-midnight description of the painted sky.",
  "Raw rescued daily data with basic transcription checks, not a homogenized climate series. Rainfall does not measure sunshine, cloud form, river flow or political events.",
  "The gauge is outside Drogheda. A dry month does not establish clear skies or dry conditions throughout the town, and the Boyne’s flow is not measured."
