# Automated Lima VM smoke test runner for hstack.
#
# Usage (macOS host):
#   ./scripts/provision/macos-lima-hstack-smoke.sh [vm-name]
#
# Env:
#   HSTACK_VERSION=latest            # @happier-dev/stack version to test (default: latest)
#   HSTACK_SMOKE_KEEP=1              # keep sandbox dir in the VM (default: 0)
#   HSTACK_RAW_BASE=...              # override raw github base (default: happier-dev/happier main)
#   HSTACK_PROVISION_PROFILE=happier # guest provisioning profile (default: happier)
#
# This script:
# - creates/configures a Lima VM (via macos-lima-vm.sh)
# - provisions dependencies inside the VM (linux-ubuntu-provision.sh)
# - runs a sandboxed `hstack` smoke test inside the VM (linux-ubuntu-hstack-smoke.sh)
