+// TestBuildTimeline_IncludesOverdueNativeTasks proves the 2026-07-12 fix: a
+// native task whose due_date is BEFORE the requested range's start must
+// still appear in the timeline, marked IsOverdue, instead of being silently
+// dropped. Root cause: GetNativeTasksByDateRange's SQL bound (due_date >=
+// start) excluded overdue tasks from ever being fetched, so ComputeDaySection
+// never got a chance to set IsOverdue -- both the web Timeline view and the
+// widget API (which both call BuildTimeline with a start of "today") showed
+// zero overdue tasks even though the Tasks tab (which calls the unbounded
+// GetNativeTasks) showed them fine.
