pub fn routed_failure(row: &Value) -> Option<String>Expand description
Why row has no modeled counterpart, if its kind is one the model does not describe.
Why a toolchain row’s routed (hybrid) simulation is no calibration point: what it came to when it did not finish
clean (the recorder’s why: deadlocked, threw, failed its gold check). The model is calibrated against routed
cycles, and a routed run that did not finish has none to compare.
