What you'll do

A freeze-guard on your most vulnerable pipe that Claude Code built — a stainless temperature probe clamped to the pipe, a low-voltage solenoid valve on a dedicated trickle line, and firmware that opens the valve to a steady stream when the pipe gets cold, closes it once it warms, refuses to chatter around the threshold, caps its own runtime, fails CLOSED on any power loss or sensor fault, and pushes you a best-effort alert every time it acts.
