"""Core-owned system MiniApps (Phase M4).

Host-level MiniApps that are not owned by a single plugin: audit activity
feed and system metrics. They register in the universal registry with
``plugin_name="system"`` at app startup and unregister with the registry
reset (tests) — they never depend on plugin activation state.

Permissions follow the owning data source:
- audit_activity -> audit:read (audit log route guard, CORE_PERMISSIONS)
- system_metrics  -> settings:read (Roadmap M4; the /system/dashboard
  endpoint itself stays require_admin — the widget degrades gracefully
  with a permission hint for non-admins)
