# Timeout Feature Validation Script
# Part of CI/CD pipeline to ensure timeout functionality works correctly

# Following Toyota Way principles:
# - Jidoka: Quality at the source through automated validation
# - Genchi Genbutsu: Go and see - actually test the commands
# - Zero Defects: No regressions in timeout functionality
