# Orchestrate the secs4java8 interop harness against our C++ server.
#
# Builds a self-contained C++ server image (interop/Dockerfile.server)
# and the Java harness image (interop/secs4j/Dockerfile), spins both
# up on a dedicated docker network, and runs the harness against the
# server.  No bind mounts — important under docker-in-docker (gitea-
# act / GitHub Actions runners with a mounted /var/run/docker.sock),
# where bind-mount sources don't resolve against the daemon's host
# filesystem.  Wired into CI via .gitea/workflows/ci.yml.
#
# Usage: bash interop/secs4j_validate.sh
# Exit codes:
#   0 — every check the harness defines passed
#   1 — one or more checks failed
#   2 — script / orchestration error
