  openapi/eridu-*-api-openapi.yml plus the live `_links` graph and registered types/taxonomies read
  from https://eridu.ai/wp-json/wp/v2/types and .../taxonomies on 2026-08-12.
note: >-
  eridu.ai registers no custom post types and no custom taxonomies — the entity graph is stock
  WordPress core. That is itself the finding: unlike providers that model a product domain in their
  CMS, Eridu's machine-readable surface carries no company-specific entity.

id_conventions:
  scheme: unprefixed auto-increment integers
  note: >-
    No prefixed identifiers (no `pst_`/`cus_` style). Ids are WordPress post ids and are only
    meaningful within eridu.ai. They are not stable across a site migration.
