A candidate's module is fetched against each package member of its group by the digest of the member's build (fetch `builds`), the member out of the fetched packages; a member not built holds it with wait-held naming the member, its bound a key of the builder's bounds state with its own time to live (A-77), a failed member or one missing past the bound fails the step naming it.
