Function fp8_quant_log 

pub fn fp8_quant_log(pick: &Fp8QuantPick, m: u32, k: u32)

Say WHICH quantizer runs and, when the lever asked for the twin and did not get it, WHICH guard refused — once per process PER BRANCH.

Not once per call: this is reached per projection per layer per step, so an unconditional line is dozens per request.
