    The API declares an empty root-level `security: []` and repeats `security: []` on every operation, which is an
    explicit OpenAPI 3.1 statement that no security scheme applies. No securitySchemes are defined because none exist.

  - No OAuth surface exists, so scopes/ is not applicable to this provider.
  - No per-caller identity means no per-caller rate limit, quota or usage attribution is possible.
