# zyginit integration test harness
#
# Black-box tests for zyginit daemon + zygctl CLI.
# Creates temporary service definitions, starts zyginit in non-PID-1 mode,
# exercises zygctl commands, and verifies expected behavior.
#
# Usage: ./tests/integration/run_tests.sh
#
# Requirements:
#   - zyginit built at build/zyginit
#   - zygctl built at tools/zygctl/build/zygctl
#
