📝 WalkthroughWalkthroughThe reconfiguration script now generates a UUID-based temporary answer-file path and uses it for logging, transfer, installation, and cleanup. The sentinel findings document records the related predictable temporary-file issue. ChangesTemporary answer-file hardening
Estimated code review effort: 2 (Simple) | ~10 minutes Merge Risk: 🟡 Moderate · up to The change makes the temporary filename unpredictable, but the credential-bearing file can remain on the remote host if upload or privileged execution fails.

temp_ans_file is removed in a best-effort finally block after upload, including
when remote execution raises, before closing the client. Ensure cleanup failures

Remove the answer file when remote execution fails.
If run_remote_sudo raises after the SFTP upload, remove temp_ans_file in a best-effort finally block before closing the client. Do not mask the original exception.
