The builder carries a binding because at genesis nothing provides
`package-registry` to resolve one from; once the forge is a module the same
consumer is told what the forge serves. Nothing held the two to the same number,
so the catalogue could drift into dialling one port before the forge is assigned
and another after.
And `at` is now protected, for the reason it had to be: a setting that moves it
points the builder, and the registry password it sends, at a host somebody else
chose.
