E.17:2 - Problem frame

  • Different readers often need different slices or presentations of the same accepted account, but a current task may need only one or two faces rather than the full quartet.
  • Informal renderings can drift semantics, hide omissions, or sever source return; composite morphisms can also lose traceability when their publication claims are used compositionally.
  • PlainView, AssuranceLane, and a packaged viewpointRef are easy to overread as U.View membership, assurance, or conformance even though none establishes those claims by itself.
  • Exact publication identity, pins, carrier relations, and evidence references matter for some receiving uses, but putting all of them before the first readable face makes ordinary publication unnecessarily hard.

MVPK therefore starts from the current source, reader/use, and minimum useful face set. It then adds viewpoint conformance, E.24.PUB occurrence/form/carrier identity, pins, bridge records, evidence, or assurance only when a named use depends on those distinctions. The optional morphism profile retains the functorial publication discipline for Description epistemes, including Description epistemes admitted for specification use. Part E is conceptual: no machine-exchange formats are specified here.
