    x-apievangelist-notes:
      idempotency: >-
        No idempotency contract. POST /workflow/runs and POST /workflow/runs/{workflow-id}/stop are not
        safely retryable.
      rate_limit_headers: >-
        None published. 10 rps on this API; exhaustion returns 429 with no Retry-After.
      error_schema_divergence: >-
        ErrorResponse sets additionalProperties:false and declares only status+message, but the docs
        error example also returns request_id and trace_id.

- target: $.servers
  update:
    x-apievangelist-server-note: >-
      A third documented base URL exists for tenants hosted in Australia -
      https://app-aws-apse2.amperity.com/api - which the spec does not declare. See
      https://docs.amperity.com/api/base_url.html.
- target: $.components.schemas.ErrorResponse
  update:
    x-apievangelist-divergence: >-
      Amperity's own responses documentation shows request_id and trace_id in the error body, which
      additionalProperties:false forbids. A strict validating client will reject a documented response.
- target: $.paths['/workflow/runs'].post
  update:
    x-apievangelist-retry-safety: not-idempotent
    x-apievangelist-note: >-
      Starting a workflow has no idempotency key. A timed-out client that retries can start the same
      courier group, orchestration group or campaign twice.
- target: $.paths['/workflow/runs/{workflow-id}/stop'].post
  update:
    x-apievangelist-retry-safety: naturally-idempotent
    x-apievangelist-note: 'Stopping an already-stopped workflow is a no-op on the target state.'
- target: $.components.parameters.ApiVersionHeader
  update:
    x-apievangelist-note: >-
      Date-string versioning under an RFC 8594 deprecation/sunset policy - at least 6 months notice,
      at least 3 months between deprecation and sunset. An unsupported value returns 400.
