Standard LoRA is quietly losing 68% of quality on FP8 hardware and most people have no idea

FP8 (E4M3) minimum representable value is 0.0625. Standard LoRA default scaling falls below that. Gradient updates underflow to zero, adapter weights freeze, run looks completely normal. You've lost 68% of model quality and had no idea. Not bad luck. Predictable given parameters that predate FP8 har
