YAML-driven test cases for the core Azure Policy compiler. These cover alias resolution, field conditions, logical operators, type coercion, count expressions, template functions, effect compilation, and policy definition parsing. 24 files, each a self-contained scenario exercised by the test runner in the companion code PR.
