The image's default CMD is bash -l, so 'docker compose run --rm devbox' with no command drops into a login shell; you pass 'opencode' explicitly to start the harness. The README quick-start claimed the opposite and carried a garbled 'Use bash instead of (no command)' half-sentence; the same error was mirrored in the Hub HUB_TEMPLATE. Fix both and regenerate DOCKER_HUB.md. Doc-only — no image bytes change.
