+"""The Monitors tab split: a panel in a group no tab renders disappears.
+
+This has silently eaten cards twice - once when tracked services moved out of
+'actions', once on the 'metrics' to 'monitors' rename. Both times the backend
+named a group the frontend did not render, and the panel was not shown, not
+logged, and not missed until someone went looking for it.
+
+The split is only correct if four places agree, and only two of them are Python:
+  1. the panels' group here
+  2. RENDERED_GROUPS in PluginAssetPanels.vue
+  3. the tab label map in PCDetail.vue
+  4. the v-show block that gives the tab a layout
+
+These tests pin the Python half so a later edit cannot quietly move a panel into
+a group nothing renders. The frontend half is pinned by its own spec.
