When-Guard Tests 🚦

Integration tests for block-level when: hygiene across roles/*/tasks/**: max-three-task guard blocks, no duplicated when-conditions across tasks, and the pure-guarded-include pattern for role inclusion.

Tests in this directory MUST only cover rules about block-level when: semantics and guard-block shape. run_once_<role> flag lifecycle checks MUST live under ../run_once/; rules about include_tasks / import_tasks target existence MUST live under ../includes/.

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