  3 doc-block tools → manage_doc_block, 3 drive ops → manage_drive_file,
  2 download tools → download_message_resource + download_doc_image.
- Wiki write: create / update / move / copy / delete_wiki_node (UAT-first).
- OKR progress writes: create / list / delete_okr_progress_record.
- Calendar write: create / update / delete / respond + get_freebusy.
- Tasks v2 domain: list / get / create / update / complete / delete_task
  + manage_task_members.
- C1.4 cookie send oc_xxx → numeric chat_id auto-resolver.
- list_wiki_nodes UAT-first (matches list_wiki_spaces).
