  Entity-relationship graph derived from the WordPress REST object shapes actually returned by
  centrexion.com on 2026-08-09. Relationships are taken from the id-reference fields on each object
  (`author`, `featured_media`, `parent`, `post`, `categories`, `tags`, `post_series`) and from the
  HAL `_links` relations WordPress emits. IDs are plain integers on this API — there are no
  prefixed or typed identifiers.

gaps:
- >-
  The 14 staff biographies rendered on the Team page are a WordPress custom post type that is NOT
  registered for REST — it is absent from /wp/v2/types and has no route. There is therefore no Staff
  entity in this graph and no relationship from Page to it, even though the content exists on the
  site. It is reachable only as HTML inside pages/16 `content.rendered`.
- >-
  The drug pipeline (CNTX-4975 and the immunology programmes) is likewise not modelled as data. It
  exists only as rendered HTML inside pages/17 `content.rendered`. There is no structured
  representation of programmes, indications, mechanisms or clinical phases anywhere on this API.
