  Captures the enhancements API Evangelist derived around the verbatim spec fetched from
  https://blocks.simbachain.com/api/member-service/openapi.json on 2026-08-27. The saved OpenAPI is
  byte-verbatim and is never mutated; everything we add lives here.

        SIMBA-hosted Blocks instance. The published spec carries no servers[] block; this host is the
        one the spec was fetched from and the one its own OAuth2 securityScheme names for
        authorizationUrl/tokenUrl. SIMBA Blocks is also deployed per-customer, in which case the base
        is that instance host (SIMBA_API_BASE_URL) with the same /api/member-service prefix.

    x-note: >-
      The spec declares an empty scopes map. The authorization server's own OIDC discovery document
      lists openid, email and profile; authorization inside SIMBA is carried by roles and permissions
      (see the Roles/Permissions tags) rather than by OAuth scopes.
