+// TestTimelineItemToWidgetItem_DootTaskGetsDueDate proves the 2026-07-12
+// clickable-reschedule fix: a doot task's raw due date must reach the
+// client via a NEW field (DueDate) that is independent of Start/IsAllDay --
+// Start is deliberately left nil for doot tasks (see
+// TestTimelineItemToWidgetItem_AllDayTask_KeepsFloatingBehavior) so the
+// client's floating-task SlotPacker can position it, and that must keep
+// working unchanged. Before this fix there was no way for the Android
+// detail popup to know a doot task's current due date at all.
