# config_dir — directory containing server_lds.conf,
# server_register.conf, server_register_client.conf,
# client.conf
# expected_policy — security-policy string that must appear in
# the client's endpoint listing (e.g.
# "Basic256Sha256", "Aes128_Sha256_RsaOaep",
# or "None")
#
# Exit: 0 when all checks pass, 1 on any failure.
# ---------------------------------------------------------------
set -uo pipefail
# NOTE: we intentionally omit "set -e" so that every check runs
# even if the client itself returns non-zero.
