A fingerprint written into a recipe names one particular copy of the base — the copy on whichever machine the person typing it was using. On any other mesh that copy has never existed, so the build stops on its first line with a message about an image nobody can look up. Three modules in the catalogue were in exactly that state, and the line each of them replaced was equally dead. A module now names the module and artifact instead, and the mesh answers with what it holds. The builder is still a thing that clones, builds and answers: the answer travels with the question, because only the mesh knows what it has. A base the mesh has not built is refused before anything is built, naming which module has to exist first.
