- Static assertions step: verifies .dockerignore exists, covers all forbidden
patterns (.env, node_modules, apps/api/scripts, .git, .planning, apps/api/tests,
apps/pwa/e2e), and --target production is still pinned in publish.yml (T-16-19)
- Boot-smoke step: runs freshly-built sha_tag image with NODE_ENV=production +
DEV_AUTH_BYPASS=true; fails if image starts (EXIT==0) or times out (EXIT==124),
passes on any other non-zero exit — proves D-08 guard fires in shipped image (T-16-18)
- Both steps ordered after build and before push; a hygiene failure blocks publish (T-16-20)
