"""
Integration accuracy tests for Chef-to-Ansible conversions.
Tests validate that generated Ansible code is:
1. Syntactically valid (passes ansible-lint)
2. Semantically equivalent to the original Chef code
3. Actually executable by Ansible
These tests complement unit and snapshot tests by verifying the real-world
usability of converted code.
