+/* Regression test for the Nodes page's Domestic/Foreign geo-scope filter.
+ *
+ * The unfiltered node list can be dominated by foreign-flagged nodes
+ * (#730 geo_filter classification — self-reported GPS outside the
+ * configured box), making it hard to see which nodes are actually local.
+ * This adds an "All / Domestic / Foreign" filter-group (public/nodes.js,
+ * matching the existing Status filter's pattern) that narrows the
+ * client-side `nodes` array by each node's `foreign` boolean.
+ *
+ * Drives the real loadNodes() pipeline (via pageMod().init()) rather than
+ * re-implementing the filter predicate, so this actually exercises the
+ * production code path — same harness style as test-issue-1606-pagination.js.
