note: 'Derived from the eighteen harvested specifications, then upgraded from the provider''s own documentation. Two
  independent models. (1) GSMA Open Gateway / CAMARA: every one of the 17 specs declares a single openIdConnect scheme
  named ''openId'' and attaches CAMARA scopes per operation; four specs additionally declare notificationsBearerAuth
  (http bearer) for the CloudEvents callback sink. The GSMA issues no tokens — the authorization server is always the
  operator''s or the aggregator''s, and the openIdConnectUrl published in every spec is the CAMARA placeholder https://example.com/.well-known/openid-configuration.
  The sim-swap spec''s scheme carries no type key, which is why the derived summary lists an ''unknown'' type. (2) GSMA
  Mobile Money API: the OpenAPI declares no securitySchemes at all; credentials travel as headers.'
