B.3.5:3 - Problem

Working-Model relations such as ComponentOf and an ordinary belongs-to sentence are easy to use but not self-justifying. Their declarations alone do not show which participants and occurrences obtain, which rule defines the relation, or what identifies the whole or collection. Conversely, exposing construction traces everywhere makes the graph unreadable to non-specialists.

We need: a stable public relation layer for relations and, where this profile is elected, a required, reconstructible grounding channel plus a visible validation intent that downstream assurance can reason about. The direct relation layer does not depend on electing the profile.
