SIE.11:2 - Problem

A source update can be treated as harmless because the schema still parses, or as universally disruptive because its version changed. Either response misses the actual reliance. Some consumers use a definition that changed; others use a different proposition from the same source; still others are merely mentioned in nearby records.

Indiscriminate revalidation consumes work without settling those differences. An incomplete search can create the opposite error: one repaired mapping is reported as proof that the entire integration remains valid.
