  "violated_contract": "A pointer gesture over hosted application content must have one owner: an ordinary click belongs to the control beneath it, a window drag belongs to the shell, and a native drag control keeps its own gesture. AppKit background dragging cannot enforce that boundary because it hit-tests SwiftUI controls as their transparent hosting view.",
  "canonical_prevention": "Classify shell clicks and window drags in one thresholded coordinator before hosted button tracking begins, and give native drag controls a typed opt-out from shell movement.",
