Autofan, Watchdog and maintenance mode

Automation should act only when its data is current and its control ownership is clear.

Autofan

• Set a realistic target and safety ceiling for each hardware group.
• Test sensor availability before enabling automatic control.

Watchdog

• Use hashrate or runtime thresholds that tolerate normal startup time.
• Avoid restart loops; terminal failures require a configuration change or explicit reactivation.

Maintenance mode

• Enable it before planned work to suppress misleading actions and alerts, then disable it when telemetry is stable.
