The bus billed every active IPowerConsumer, but a behaviour group stops at its Thermotoggle: a heater above its target never runs its EnergyDraw, yet its full draw (1000-2500/s) was charged every tick. On an idle station that kept the reactor in permanent deficit, overloading at overload efficiency. The bus now skips a consumer whose group has a closed thermostat ahead of it, the same rule it already applies to inactive items; Thermotoggle.Open is the one statement of when a thermostat is open, and Execute returns it. Tests (Soul's F2; S17 survived before): from a hull at one uniform temperature, one tick below the heater's target raises its cells and one above does not, so the heater's own contribution is measured with no reactor heat in it; and the bus bills the heater's draw below its target and not above. This does not keep an idle station warm (Soul's F1, reported separately): the reactor's throttled idle heat alone still drives it past its plateau.
