  Derived from the id-reference query parameters the host's own route-discovery document declares on
  each collection (`parent`, `author`, `post`, `categories`, `tags`, `media`). Those parameters are
  the machine-readable evidence of the relationships below. Response object schemas are not typed in
  the discovery document, so property-level detail is deliberately absent rather than guessed.
entities:
- name: Post
  collection: /wp/v2/posts
  operations: [listPosts, getPost]
  id_type: integer
  note: The site's news / press-release stream, surfaced at /investors-media/.
- name: Page
  collection: /wp/v2/pages
  operations: [listPages, getPage]
  id_type: integer
  note: Static corporate pages — about-us, our-science, pipeline, partners, careers, contact-us.

  collection: /wp/v2/media
  operations: [listMedia, getMediaItem]
  id_type: integer

  collection: /wp/v2/tags
  operations: [listTags, getTag]
  id_type: integer
  taxonomy: post_tag
- name: Comment
  collection: /wp/v2/comments
  operations: [listComments, getComment]
  id_type: integer
- name: Type
  collection: /wp/v2/types

  operations: [listTaxonomies]
  id_type: string
  note: Vocabulary — the registered taxonomies.
- name: Status

  operations: [listStatuses]
  id_type: string
  note: Vocabulary — the registered post statuses.
- name: SearchResult
  collection: /wp/v2/search
  operations: [listSearch]
  id_type: integer
  note: A projection over Post and Page, not a stored entity.
relationships:
- from: Post

  evidence: '`tags` / `tags_exclude` filter parameters on listPosts.'
- from: Post

  kind: belongs_to

  evidence: '`parent` / `parent_exclude` filter parameters on listComments.'
- from: SearchResult
  to: Post
  kind: has_one
  via: id
  evidence: '`subtype` / `type` parameters on listSearch resolve results back to posts and pages.'
gaps:
- entity: User
  reason: >-
    /wp/v2/users returns HTTP 401 anonymously, so the author relationship (Post belongs_to User via
    `author`) is declared by the `author` filter parameter but the entity itself is not publicly
    readable and is not modelled in the OpenAPI.
