  {
   "claim": "Did this summer offer the kind of light the title evokes?",
   "result": "The Weather Bureau classifies 52 of 122 days as clear (42.6%). Clear conditions recur, but are a minority category. Neither the counts nor the rainfall identifies Graves’s summer or the light at the doorway."
  }
 ],
 "finding": "A sale before summer 1931 shifts the test to the latest possible summer, 1930: relatively dry at Portland, with 52 days classified clear. The painting can draw on an earlier summer; its actual weather remains unknown.",

  {
   "claim": "Light available in the latest possible summer",
   "verdict": "Partially agrees",
   "reason": "Published clear days show recurring regional opportunities for a sunlit garden; the year and garden conditions are not established."
  },
  {
   "claim": "The actual painted summer, day and changes made by Graves",
   "verdict": "Unknown",
   "reason": "The sale gives an upper bound; no dated session, identified doorway or making record fixes the scene."
  }
 ],
 "limits": [
  "June–September 1930 is the latest possible summer test, not the painted summer. Earlier summers, sketches and later studio work remain possible.",
  "Cloud categories and cloudiness are not sunshine-duration measurements; numerical category cutoffs were not established from the consulted guide. No sunshine-hour total or historical sunshine rank is claimed.",
  "Precipitation sums require every daily amount to be unflagged or a documented trace; missing and presumed-zero amounts exclude a season. Trace days add no quantified depth. Ranks compare matching complete seasons only, with ties sharing rank.",
  "The 44-season archive is not homogenized. Exposure and observation practices may differ. No same-station 1991–2020 normal can be made from a city file ending in 1940; no airport splice or station average is used.",
  "Printed July rain is 3.59 inches; rounded daily data give 3.60 inches. Both are retained separately. Cloud counts are read directly from the scans, with the maximum-wind date column excluded.",
  "No object-linked weather witness, full making history or open artwork-image licence has been established. The original letter and 1913 Tarkington catalogue have not been inspected."
