E.17.1:13.1 - What a viewpoint member should make explicit

Each U.ViewpointRef member inside a reusable bundle resolves to one exact viewpoint episteme edition whose claim content makes explicit at least:

• the concern family it brings into focus,
• exact stakeholder or audience referents only when they change the concerns,
• the exact target-kind criterion it carries and the compatibility condition under which this family can reuse it,
• the independently admitted episteme kinds whose exact membership rules allow candidates under that viewpoint,
• any bundle-specific conformance notes later users must retain, plus an exact reference that resolves to the comparison claim or F.9 Bridge when either has independently been established; a note or reference creates no correspondence.

E.17.1 does not redefine the internals of U.Viewpoint. It states what must remain visible if a viewpoint is to be reused as part of a bundle rather than as an undocumented local label.
