The Dockerfile's builder stage already runs the unit suite, so the workflow deliberately has no separate test job -- a red test cannot produce an image. After pushing, the published artifact is smoke-tested by digest: `--version` covers a runtime stage missing a shared library, and `--check` against a throwaway credentials file covers the config baked into the image. Both were failure modes a green build would not have caught. The `--check` invocation is verified locally against docker/openvpngate.conf. `latest` follows the newest v* tag rather than the branch head; master head is published as `master`. Registry paths are lowercased explicitly rather than relying on metadata-action, since the same value is reused for the smoke test. GHCR_TOKEN / GHCR_USER / GHCR_IMAGE override the built-ins so this still works from a mirror or a Gitea/Forgejo runner, where the ambient token authenticates to the wrong registry. On github.com none of them need to be set. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com>
