Both blocks were nearly identical (config.json.sim's differing M and unused gain key being the only divergence), so there's no need for per-config tuning here. DEFAULT_PLANT_PARAMS in brewpi.py now feeds both the real Pot plant and the temperature controller's Smith-predictor model. No demo scripts read these config keys, so nothing else needed updating.
