- Remove unused Ecto.Query import from device_poller_worker_test - Update route paths from /orgs/:slug to /dashboard after navigation refactor - Fix HostParser tests to match actual hostname resolution behavior - Update UserAuth redirect assertions to expect /dashboard instead of /devices - Fix DashboardLiveTest missing organization context - Fix OrgLive.NewTest to verify organization creation correctly All 4850 tests now passing with zero failures and zero warnings.
