go_packages and go_retention read the forge's Go registry as npm_* read npm's: a version a
go.mod on a default branch requires (or replaces to) is kept, with the newest keep; a go.mod
that cannot be read stops a real run before anything is deleted; each deletion says removed
on the Go seat, under the module path and without Go's leading v (design 51 *Retention*).
