Breaking Changes

​
Terminology Restructure: Gateway/DUT to Box

This release standardizes terminology across the entire codebase, replacing “gateway” and “DUT” (Device Under Test) with the unified term “box”. CLI Changes:
  • The --dut option is now --box (hidden alias kept for backward compatibility)
  • The --gateway option is now --box where applicable
  • All help text and error messages now use “box” terminology
Configuration Changes:
  • The DUTS key in .lager configuration files is now BOXES (backward compatible - old format is still read)
  • Box storage functions renamed (e.g., load_duts() → load_boxes())
Directory Structure:
  • gateway/ directory renamed to box/
  • gateway/lager/lager/ flattened to box/lager/
  • gateway_http_server.py renamed to box_http_server.py
  • start_lager.sh renamed to start_box.sh
  • Deployment scripts renamed:
    • setup_and_deploy_gateway.sh → setup_and_deploy_box.sh
    • secure_gateway_firewall.sh → secure_box_firewall.sh
    • verify_gateway_security.sh → verify_box_security.sh
Migration:
  • Existing .lager configuration files will continue to work
  • The --dut CLI option works as a hidden alias for --box
  • Update any scripts or automation to use the new --box option
