A member counts as observed when at least one active (non-shadow) sensor lives on its registrable domain or on a host it declares. Shadow sensors are new sensors the Source Factory found and validated; they are polled and their evidence is kept, but nothing is published until they prove signal over noise. Universes live in <code>config/coverage/*.yaml</code> with provenance and retrieval dates; they are the denominator, not the registry.63        {c.issues.length > 0 && <span className="text-warn"> {c.issues.length} universe file{c.issues.length > 1 ?
