"""Every-three-minute native running-late poll; host owns actual notification sends.

On success emits wake_agent:false with bounded count metadata: the host already
owns each native dispatch and its delivery budget. Never ask the model to send an
additional lateness notice. On failure emits fixed stderr/nonzero and a false wake
payload; task/host failure monitoring owns repair, never another API or resend.
No event state, route, contact, context flag or approval is supplied by this script.
