A.6:4.3 - View membership needs exact viewpoint conformance

MultiViewDescribing makes the candidate episteme and exact viewpoint episteme explicit. The candidate has U.View membership only when E.17.0 conformance obtains. A projection or query may participate in an A.6.3 construction, but that construction does not establish membership. MVPK separately uses publication face designators (PlainView, TechCard, InteropCard, AssuranceLane) and their E.17 profiles. E.17:5.2 specifies the declared publication-face kind values.

A disciplined stack therefore requires:

  • Every published face use identifies the selected episteme and its separate reader/use declaration. Name the exact viewpoint episteme through U.ViewpointRef when U.View membership or viewpoint identity is used; name the publication occurrence, form, and carrier when those identities change publication or reliance. The face designator is not any of those objects.
  • Calling the selected episteme a U.View requires E.17.0 conformance; a face label, viewpoint reference, projection history, or publication does not establish it.
  • Per E.17 (“no new semantics”), a face MUST NOT introduce a new semantic commitment or any new object or claim selected through A6-AW-*. A face MAY add informative explanation, examples, and cross-references that preserve the source claims. Normative face prose cites the canonical L/A/D/E claim ID or location and direct object; it may faithfully paraphrase the claim. Add any new boundary claim to its canonical source before publishing it on a face. Use verbatim text when exactness is critical or disputed.
  • Per E.17 and publication-face and publication-form discipline (face‑kind closure), a publication package that claims MVPK alignment MUST NOT mint additional MVPK face kinds (e.g., “EvidenceCard”, “NormsCard”) as if they were first‑class kinds; if you need local headings, keep them as sections within the selected faces.
