Domain Tests 🌐

Integration tests that enforce the shape and uniqueness of domains.{canonical,aliases} across all roles and validate that get_domain() references point to real application_ids.

Tests in this directory MUST only cover domain declarations (structure, uniqueness, reference validity). Tests related to port registration, OIDC redirect URIs, or CSP handling MUST live elsewhere under tests/integration/.

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