  note: >-
    Non-destructive. Captures what API Evangelist established about this contract from the
    provider's own documentation and from live probes; the harvested spec itself is never
    mutated. Applying this overlay adds the absolute regional server the spec omits, the
    licence and contact metadata, and the runtime response headers observed on a live call.

    description: >-
      The published spec carries only title, description, version "latest" and a contact
      email. Add the documentation and terms links the provider publishes.

      servers[] in the published spec is the relative path "/latest", which names no host. The
      SDK's own regionBaseURL() resolves it to https://api-{region}.stack.tryrelevance.com,
      with region one of bcbe5a (US), d7b62b (EU) or f1db6c (AU). Add the templated absolute
      form plus the three concrete regional servers, so a client can resolve a callable base.

          description: >-
            Server-sent-events stream, as constructed by the SDK's regionStreamingURL(). Not
            described anywhere in the OpenAPI.
  - target: $.components.securitySchemes.AuthorizationHeader
    description: >-
      The scheme's description states the header format but the spec gives no example and no
      key format. Add both from the provider's authentication documentation.
    update:
      x-key-format: 'project_id:sk-...  (API key), or a runtime-generated embed key'
      x-docs: https://relevanceai.com/docs/sdk/authentication
      x-key-scopes: >-
        API keys grant unrestricted access to every resource in the project. Embed keys are
        generated at runtime and scoped to a single public agent or a single workforce.
  - target: $
    description: >-
      Runtime response headers observed on a live unauthenticated request to
      POST /latest/agents/list. None of these appear in the published spec.
    update:
      x-response-headers:
        x-request-id: Per-request correlation id, also echoed as the error_id header.
        error_id: Mirrors x-request-id on error responses; quote it to support.
        x-trace-id: Present but returns the literal "x-trace-id-deprecated".
        access-control-expose-headers: 'x-trace-id, x-request-id, error_id'
      x-rate-limit-headers: >-
        NONE observed. The API returned no X-RateLimit-*, RateLimit-* or Retry-After header on
        a live call, and the docs publish no HTTP rate limits — capacity is governed by
        per-tier Action / Vendor Credit quotas and a per-tier concurrent-task ceiling instead.
  - target: $
    description: >-
      The spec documents a 200 response on every one of its 566 operations and no 4xx or 5xx
      at all. Record the real error envelope observed live, so a consumer is not left to guess.
    update:
      x-error-envelope:
        media_type: application/json
        rfc9457: false
        fields:
          message: Human-readable error string.
          error_type: 'Machine token; observed value "unset_error_type".'
          error_audience: 'Observed value "platform".'
        observed_status_codes: [403, 422]
        note: >-
          Derived from live probes only: 422 from POST /latest/agents/list with an empty
          body, 403 from the /.well-known/ prefix on the same host. See
          errors/relevance-ai-problem-types.yml.
