      x-host-caveat:
        article_endpoint_host_published: false
        detail: >-
          Leena AI supplies the connector host per tenant. The server entry is templated
          rather than guessed.
  - target: $.paths['/api/integration/articles/sync/'].post
    description: >-
      Record the upsert-by-reference_id behaviour, which is the connector's de facto
      idempotency mechanism.
    update:
      x-agentic-access:
        action-class: write
        consequence: medium
        reversible: true
        rationale: >-
          Writes content into the knowledge base that grounds agent answers. Bad content
          propagates into employee-facing responses.
      x-idempotency:
        supported: true
        mechanism: upsert-by-key
        key_field: reference_id
        key_header: null
        guidance: >-
          There is no Idempotency-Key header, but articles are keyed on the caller-supplied
          `reference_id`, so re-syncing the same reference_id updates the existing article
          rather than creating a duplicate. Use a stable source-system identifier.
      x-ordering:
        guidance: >-
          Upload attachments with uploadKnowledgeAttachment first and collect their
          attachment_id values, then reference them from this call. Attachments cannot be
          attached retroactively in a single step.

    description: Record the supported file types as a machine-readable list.
    update:
      x-agentic-access:
        action-class: write
        consequence: low
        reversible: true
      x-supported-file-types:
        - PDF
        - DOC
        - DOCX
        - TXT
        - HTML
        - XLS
        - XLSX
        - PPT
        - PPTX
        - PNG
        - JPEG
  - target: $.paths['/sync/complete/'].post
    description: Record that this is the indexing trigger and should be called once per bulk load.
    update:
      x-agentic-access:
        action-class: write
        consequence: medium
        reversible: false
        rationale: Triggers reindexing of the knowledge base after a bulk load.
      x-usage:
        call_once_per: bulk migration
        guidance: >-
          Call only after every article in the migration has been synced. Calling it
          mid-migration indexes a partial corpus.
  - target: $.components.securitySchemes.bearerAuth
    description: Flag the short token lifetime specific to this connector.
    update:
      x-token-ttl-minutes: 30
      x-guidance: >-
        The KM connector's documented token validity is 30 minutes — half the 3600 seconds
        documented for the AOP and Audit Logs APIs. Bulk migrations will outlive a single
        token, so implement refresh in the middleware as Leena AI recommends.
  - target: $.components.schemas.ArticleSyncRequest
    description: Flag the HTML validity requirement that is a common integration failure.
    update:
      x-validation-note: >-
        `html_content` must be valid HTML. Malformed markup is the documented failure mode
        for this operation.
