      Shipped as Railz until FIS acquired the company; FIS's own developer page lists
      dashboard.railz.ai as an FIS developer portal and info.title is FIS-branded.

  update:
    security:
    - bearer: []
    x-apievangelist-note-security: >-
      The original declares the bearer scheme in components.securitySchemes but applies it to no
      operation and declares no top-level security. This overlay adds the top-level requirement
      the docs state in prose, so a generated client sends a credential instead of taking a 401
      on every call. It does not change the API.
- target: $.info
  update:
    x-apievangelist-gaps:
      idempotency: none — no Idempotency-Key on any of the 86 mutating operations
      rate_limit_headers: none emitted; 429 documented without a threshold or Retry-After
      request_tracing: no correlation or request-id header
      deprecation: v1 operations superseded by /v2/ are not flagged deprecated
      error_format: vendor envelope, not RFC 9457; message is an array of strings
      four_oh_four: declared on 1 operation despite 32 operations taking an {id} path parameter
      tags: the contract declares no tags at all, so no operation is grouped
