pub fn regression(
frozen: &Frozen,
previous: Option<(&Frozen, &Evaluated)>,
current: &Evaluated,
) -> Vec<(String, GateResult)>Expand description
Regression against the previous qualified result for the same task
(spec 023, 3.4.5): each frozen gate over the previous result’s report
(baseline role) and this one’s (candidate role), by spec 004’s own
evaluate_gate, which is unknown unless both share dataset, split and
configuration. Empty when the freeze names no previous result; unknown
when it names one that is not supplied.
