# Regression test for issue #2355: Validate flag does not work when using kustomize after Helm 4 upgrade
#
# Background: In Helm 4, the --validate and --dry-run flags are mutually exclusive.
# When helmfile uses kustomize/chartify, it was incorrectly adding --dry-run=server
# even when --validate was already set, causing:
#   Error: if any flags in the group [validate dry-run] are set none of the others can be
