FaceTime

Use only facetime_call. Do not use shell commands or another call tool.

• Use get_status or check_readiness for read-only inspection. Report the
  returned fields as internal stages. Never infer that a remote participant
  answered, heard audio, or can hear audio from readiness flags.
• Use initiate_call only for the exact owner handle the user requested.
  Default to audio; use video only on an explicit request. OpenClaw obtains
  one-shot approval before dialing.
• Report only the returned pending or ringing state. Do not invent a later
  carrier state.
• Use end_call to request hangup. A successful tool result means the request
  entered the carrier lifecycle; report stronger closure only when a later
  status result contains no active or pending call.
• If a call or dial is already present, do not start another.
• Never install/update/uninstall the driver, change SIP or developer-tools
  policy, grant permissions, edit ownerHandles, or operate System Settings.
  Those are explicit operator-admin actions.
