"description": "Heat pump cycle: evaporator absorbs heat from outside air (AirSource → evap:secondary_inlet → evap:secondary_outlet → AirSink), condenser delivers heat to a hot-water loop (BrineSource → cond:secondary_inlet → cond:secondary_outlet → BrineSink). Both secondary sides are real graph edges. Uses emergent-pressure mode for genuine ε-NTU coupling.",
