    - name: RELEASE_TOOLS_IMAGE
      description: |
        Pre-built release-tools image containing govulncheck (and other tools).
        Used only for the govulncheck step.
      type: string

    - name: LINT_REQUIRED
      description: |
        If "true", lint findings fail the build. If "false", lint runs but its
        exit code is ignored (warn-only). Flip to "true" after baseline cleanup.
