Service Registry Tests 🛰️

Integration tests that validate the service registry discovered from roles/*/config/main.yml: canonical aliases are consistent, every service key resolves via plugins/lookup/service.py, sys-svc-* roles carry a system_service_id matching their folder, and transitive dependencies (e.g. dashboard → mailu) are declared correctly.

Tests in this directory MUST only cover service-registry semantics. Tests for application_id identity MUST live under tests/integration/roles/applications/id/, and generic role-structure rules MUST live under tests/integration/roles/.

For framework, directory layout, and make test-integration usage see integration.md.
