   "claim": "How do the three nearby years compare with the station’s longer record?",
   "result": "At Mount Hope, 1909 is coolest among the complete May–September seasons retained from the file. Both neighbouring years are warmer. Scarsdale’s three target seasons have gaps and cannot be ranked."

  {
   "claim": "Does this test the painted sky or reveal Lawson’s changes?",
   "result": "No. Thermometer records and a broad visual season do not identify a day, verify the sky, or document alterations."

   "claim": "The painted sky and day",

 "limits": [
  "May–September is Nephos’s visual interpretation of foliage and flowers, not a museum statement or a plant-based date.",
  "1908, 1909 and 1910 are considered separately because they surround the approximate catalogue date; they are not documentary bounds on the picture.",
  "Ranks use only complete same-station seasons. Historical instrument exposure and comparability have not been verified.",
  "Missing readings remain missing, stations and years are not pooled, and no complete rainfall total or wetness rank is published."
