The root Dockerfile builds the only image; Dockerfile.backend is gone. Its stages: lint, a Go stage that runs the tests and builds netwatch-server, the node stage, and an nginx runtime. nginx serves dist/ on 8080 and proxies /api/ and /.well-known/healthcheck to the backend on 127.0.0.1:8081. bin/entrypoint.sh starts both, turns TERM or INT into a stop of both, and exits non-zero when either exits on its own. The backend runs as user netwatch and keeps reports on the /data volume. New setting BIND_ADDRESS (empty: every interface). STOPSIGNAL is SIGTERM, since the nginx image's SIGQUIT would miss the entrypoint. script/docker is the org model verbatim. Model: opus-5-5
