x-note: >-
  Non-destructive enhancement layer over the provider's published OpenAPI 3.1.0. It records the operating context the
  spec omits — production and EU hosts (the document declares only the certification server), the external artifacts
  this profile derived, and the contract gaps found during enrichment. It never rewrites the harvested document, and
  it does not invent operationIds: the absence of operationIds across all 167 operations is recorded as a finding for
  the provider, not patched over here.

  update:
    x-contract-gaps:
    - id: no-operation-ids
      detail: >-
        None of the 167 operations declares an operationId, so no stable machine identifier exists for any endpoint.
        Every downstream artifact in this profile has to address operations by method plus path.
      affected_operations: 167
    - id: no-rate-limit-contract
      detail: >-
        HTTP 429 is described in the error-handling guide but is not enumerated in any operation's responses, and no
        numeric limit or RateLimit-* / X-RateLimit-* response header is published.
    - id: no-problem-details
      detail: Errors are plain application/json with an `error` string; RFC 9457 application/problem+json is not used.
    - id: single-server-declared
      detail: >-
        The published document declares only https://api.cert.zerohash.com, so a client generated straight from the
        spec points at the certification environment.
    - id: stale-download-link
      detail: >-
        info.description links to /zh-swagger.json for the JSON download; that URL returns HTTP 404 on
        docs.zerohash.com as of 2026-08-05.
    - id: no-deprecation-policy
      detail: >-
        One operation (GET /market_data/image/{path}) is marked deprecated, but no Sunset/Deprecation header support
        or written deprecation policy exists to tell an integrator when it goes away.
