    This overlay records API Evangelist observations ONLY; the harvested contract is never mutated.

      x-apievangelist-harvested: '2026-09-10'
      x-apievangelist-source: https://api-docs.fraud.net/docs/public-apis/b95a796f3265e-api-reference
      x-apievangelist-spec-version: swagger-2.0
      x-apievangelist-note: >-
        The only host declared is a SANDBOX host (api-sandbox.c008-m008-us.fraud.net).
        No production base URL is published; production is per-tenant and per-region.
  - target: $.securityDefinitions
    update:
      x-apievangelist-observation: >-
        The document's global `security` requirement names `new-auth`, but the only scheme
        defined here is `basic-auth`. That is a dangling security reference in the
        published contract. The narrative documentation states HTTP Basic unambiguously.
  - target: $.responses['trait:responseApi:409']
    update:
      x-apievangelist-idempotency: >-
        This is Fraud.net's replay protection — duplicate rejection on the natural key
        order_id. It rejects rather than replays, so a retried write returns 409 and not
        the original risk score. Coverage is partial: 9 of 13 operations declare it.
  - target: $.responses['trait:updateResponseApi:409']
    update:
      x-apievangelist-idempotency: >-
        Update-surface replay protection, keyed on the pair (order_id, updated_on).
  - target: $.paths['/v2/account/login'].post
    update:
      x-apievangelist-spec-gap: >-
        Declares only a 200 response. No 401/403/406/409/5xx is documented for this
        operation even though the shared response traits exist in the same document.
  - target: $.paths['/v2/risk/account/loan'].post
    update:
      x-apievangelist-spec-gap: Declares only a 200 response; error traits not applied.
  - target: $.paths['/v2/risk/transaction/account_application'].post
    update:
      x-apievangelist-spec-gap: Declares only a 200 response; error traits not applied.
  - target: $.paths['/v2/risk/transaction/banking_marketplace'].post
    update:
      x-apievangelist-spec-gap: >-
        Declares 401/403/404/406/5xx but omits 409, unlike every other Check operation.
  - target: $.tags
    update:
      x-apievangelist-observation: >-
        Five tags are declared (Banking / Fintech, Commerce, Bank, Loan, Identity) but
        only three are used by operations; `Bank` and `Loan` are declared and never
        applied.
