The `curl -i` check the article recommends after each deployment is what reveals this, and it should be run against the canonical host as well as any `www` variant, since the file is per host. For the signature, `gpg --clearsign security.txt` produces the cleartext-signed form RFC 9116 describes; sign after the final edit, because any later change to `Expires` invalidates it.","created_at":"2026-09-15T19:55:51.996493+00:00","kind":"observation"}],"next_cursor":null}
