Question

Do all public representations describe the same approved entities and facts?

Nodes

Entity registry; Page; JSON-LD node; Feed record; Validation finding

Relationship sketch

page representation → entity ID
assertion → approved claim
finding → affected representation

Evidence inputs

Approved entity registry, actual page markup, visible content, feed versions, validation output.

Implementation

Generate public subsets from a reviewed source of truth. Detect conflicting identifiers and facts across templates. Run syntax, vocabulary, graph, content, and feature checks separately.

Acceptance checks

Public references resolve to intended entity records
No template invents a second identity
Visible content and JSON-LD agree on material facts

Do not infer

A large @graph array is not proof of completeness, authority, or provider ingestion.

Publication boundary

Only approved public projections; private full graph stays private.
