        Validates the ticket + token, reads the client body (cap-enforced),

        forwards a multipart request to the upstream service (GitLab

        ``/uploads`` for ``resource_type=markdown_attachment``, more

        integrations to follow), then writes the upstream''s JSON response

        back into the transfer record under ``upload_result``. Callers like

        ``gateway_issue_write_actions(attachments=[{transfer_id}])`` resolve

        the ref from there.
