Development record

The dogfood remote check accepts an ssh or https remote on this machine: localhost, 127.0.0.0/8, ::1 and [::1]. An agent running as the account can move such a remote, and the docs state it as the person's residual because abcd cannot tell an ssh alias from a forge. Refusing the literal loopback names would cost nothing for a real forge and would match the refusal of filesystem paths, as defence in depth that an alias still escapes.
