E.17.0:2 - Problem
How can an engineer recognize and use views under explicit viewpoints while preserving exact episteme identity and direct relation semantics, without treating a selected viewpoint, a query result, a diagram, a family label, or a publication as what makes an episteme a view?
The common practical failure is not merely loose wording. The wrong object is used to justify the next action. A generated table is accepted as a view because it was generated; a published diagram is accepted because it is readable; a viewpointRef is treated as proof of conformance; or several documents are put in one package and called a multi-view model without recovering any cross-view relation.
