Contract
- Show the same refund branch (small vs large) as a short graph

- Print both paths and final status

Sample run — exact text can vary
=== small refund ($12) ===
[lookup] order 4412 amount=12.0
[auto_refund] $12.0 for 4412
final: {'order_id': '4412', 'amount': 12.0, 'status': 'refunded', 'path': 'auto'}
=== large refund ($900) ===
[lookup] order 4412 amount=900.0
[ask_human] would pause / checkpoint here in a real app
final: {'order_id': '4412', 'amount': 900.0, 'status': 'wait_human', 'path': 'human'}
