The url was skipped by the installation check, so an installation's host or an address passed; it is judged whole now, the vendor's host declared in the artifact's names-on-purpose, and an address or a reserved name as the host is refused. Only the version's dotted-quad reading is skipped. The unpack caps its entries, drains xz before waiting for it, reads a pax global header and a nested within's parents, and a redirect off https is not followed.
