Wikipedia:Articles for deletion/Envelope model
Whether or not we keep an article is '''based on policy''', not if something exist, not on content, not on usefulness. At a bare minimum an article needs to meet  or the criteria outlined in a subject-specific guideline for notability. Even then an article is only presumed to be suitable for a stand-alone article and not guaranteed as the article may violate a policy of Wikipedia
— NONE, NONE
