```

Start at common_startup_entrance.py and follow the os_selector.py import chain shown in the traceback. Reproduce the patch operation on Ubuntu 20.04, then inspect the bundled boto3, botocore, urllib3, and system OpenSSL interaction around OpenSSL/crypto.py. Done means the patch baseline operation loads and runs without the X509_V_FLAG_NOTIFY_POLICY AttributeError.
