Original automation module from the submitted project. Lab credentials and the device inventory are not published.

# verify.py
# Automated Operational Validation Engine
# Connects to CORE-SW post-deployment and parses live operational state
# (ACL tables, static routing table, VLAN database) to confirm the automation
# suite configured the device correctly, without manual CLI inspection.
