+# A search result must open the page that actually contains the setting.
+#
+# Every schema group routes to one page in services/SettingsSearch.qml, and the
+# ownership rule in modules/settings/README.md derives a setting's owner from
+# that route. Nothing checked the two agreed, and two groups had drifted:
+#
+#   weather routed to Appearance while every weather control lived on Home, so
+#   searching "temperature unit" opened a page without it.
+#
+#   vitals routed to Appearance, but the refresh interval sat on Home while the
+#   toggles it governs sat on Appearance -- one concept, two pages, which is
+#   precisely what the ownership rule forbids.
+#
+# Neither is visible from the code: each page is coherent on its own, and only
+# following a search result reveals the mismatch.
+#
+# Groups whose settings are driven by bespoke UI rather than schema-bound rows
+# are skipped, because there is nothing to locate.
