+
+This prevents the class of bug where ``set_fact`` tasks use
+``{{ targets | to_json }}`` to store Python lists, but ``to_json``
+converts native types to JSON strings. Ansible then stored the result
+as a string, so iterating over the fact yielded individual characters
+instead of list items, causing ``object of type 'str' has no attribute
+'ip'`` errors.
+
+The check scans all Ansible task files (playbooks and role tasks) for
