  x-source: openapi/malwarebytes-threatdown-oneview-openapi.json
  x-note: >-
    Additive OpenAPI Overlay 1.0.0 capturing API Evangelist's enrichment of the harvested
    ThreatDown OneView definition. It never mutates the original file. OneView is the
    multi-tenant MSP projection of the same platform as Nebula, so it inherits the same
    error, pagination and rate-limit gaps, and adds a deprecated subscription surface.

  description: Record the multi-tenant addressing model that distinguishes OneView from Nebula.
  update:
    x-tenancy:
      model: multi-tenant MSP
      tenant_param: account_id
      tenant_param_in: path
      used_on_operations: 141
      hierarchy_field: parent_account_id
      delegation_header: on-behalf-of
      delegation_used_on_operations: 7
      site_entity: >-
        A Site is the MSP-managed customer. It gains an account_id once a Subscription is
        attached, and that account_id is then used for all endpoint-security operations.
      artifact: data-model/malwarebytes-data-model.yml
- target: $.info
  description: >-
    Flag the deprecated subscription surface. The operations carry `deprecated: true` but
    no Sunset header, removal date, or replacement pointer.
  update:
    x-deprecations:
      count: 6
      sunset_header: false
      removal_date: null
      replacement_documented: false
      operations:
      - api.v2.oneview.create.subscription.id
      - api.v2.oneview.delete.subscription.id
      - api.v2.oneview.get.subscription.id
      - api.v2.oneview.update.subscription.id

  description: Record the cursor pagination contract and its inconsistencies.
  update:
    x-pagination:
      style: cursor
      request: [next_cursor, page_size]
      response: [next_cursor, total_count]
      inconsistency: >-
        A small number of operations still take `per_page` instead of `page_size`, and
        sorting uses sort_field/sort_direction here where Nebula uses sort_by/sort_order.

  description: Record that no request-idempotency mechanism exists.
  update:
    x-idempotency:
      supported: false
      header: null
      note: >-
        Site creation, user provisioning and job issuance are all non-idempotent. In a
        multi-tenant MSP context a retried Site creation can produce a duplicate customer.

      The `read` scope description reads "Read data of your Nebula account" in the OneView
      definition — copied from Nebula and never adapted to Sites. Report upstream.
- target: $.info
  description: Record the structural review findings for this definition.
  update:
    x-api-evangelist-review:
      strengths:
      - 401 operations, each with a unique operationId, summary and description
      - Per-operation scope plus granular permission declared
      - Deprecated operations honestly flagged in the definition
      defects:
      - No 4xx or 5xx response declared on any operation.
      - components.schemas is empty; all schemas inlined, producing a 19.6 MB document.
      - >-
        The `authorization` header is declared as a plain required parameter on 400 of 401
        operations in addition to the securityScheme.
      - Scope descriptions still reference Nebula rather than OneView.
      - >-
        Six deprecated operations carry no Sunset header, no removal date and no
        replacement pointer.
      - No response examples anywhere in the definition.
