E.17.2:8 - Pattern contributions and boundaries

• E.17.2 provides the four-position project authoring template and its concern distinctions. It supplies no exact L, declaration, reference, P edition, or membership occurrence; a project materializes those objects through the patterns below.
• Use E.17.0 for U.Viewpoint and U.View membership, ViewpointConventionDependencyRelation, EpistemeViewpointConformanceRelation, and ordinary-use stops.
• Use E.17.1 for catalogue L, local family declarations, and packaging by exact viewpoint references; it admits no bundle U-kind.
• Use C.2.1 to identify every constituent episteme, Q, P, candidate E, assertion, and description.
• Use C.13 to construct exact collections and A.22 to select structures.
• Use A.6.3 only for optional source-to-receiving viewing construction; that construction does not grant view membership.
• Use A.3.1/A.3.2 for Methods and MethodDescriptions, A.3.4 for transformations, A.2 for local system-role kinds, C.3.2 for their KindSignature declarations, four-input classification judgments, and optional extensions, A.2.1 for exact U.SystemRoleAssignment species and occurrences, A.2.2 for capabilities, A.2.7 for relations among system-role kinds, the direct responsibility pattern for responsibility, E.18 for transformation flows, and B.1.1 plus applicable module or interface patterns for dependency, module, and interface relations.
• Use E.24.PUB for publication objects and relations and C.29 for representations of independently recovered objects or relations.
• Use A.6.RCD to state or derive a needed relation claim, or return its exact blocker, when current predicates are insufficient.
