Vars & Defaults Tests 📐

Integration tests for cross-role variable and defaults hygiene: TOP_LEVEL_CONSTANT uniqueness across roles/*/vars/**, roles/*/defaults/**, and group_vars/**; and the prohibition against overriding Ansible facts via vars: or set_fact:.

Tests in this directory MUST only cover rules about variable DEFINITION hygiene (uniqueness, naming, override prohibitions). Rules about variable USAGE in Jinja templates MUST live under jinja/.

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