  {"claim": "What did Lane change?", "result": "The catalogue documents removal of the drawing’s foreground shore, foliage and tree when Lane made the oil."},
  {"claim": "What rainfall context survives for the reported sketch month?", "result": "A low August total at Brunswick and few positive daily entries at Steuben. Each station remains separate; neither measures the harbor."},
