Enum FitStationarityEvidence 

pub enum FitStationarityEvidence {
    Certified {
        residual: f64,
        bound: f64,
    },
    NoComparison,
}

What an assembly-time convergence gate weighed (#2427/#2530).

A residual and the bound it was weighed against are one fact, not two. They used to be two independent Option<f64> fields filled from DIFFERENT sources with asymmetric fallbacks: the residual fell back to the exported outer gradient norm when no certificate existed, the bound had no fallback. A run with no certificate therefore rendered stationarity residual Some(0.0) against None – a residual weighed against nothing, printed as though a comparison had happened, and recorded verbatim on #2471.

EstimationError::RemlDidNotConverge already forbids that shape one variant up. This is the same repair here, and it REMOVES the fallback rather than symmetrising it: if no certificate was assembled then no first-order comparison was made, and substituting a norm of different provenance is an absent measurement scored as a value.

Variants

Certified

A residual measured at the rejected point, weighed against bound. Both come from the SAME certificate, so they are one comparison.

Fields

residual: f64

bound: f64

NoComparison

No comparison was made: there was no certificate to take a residual and a bound from. The refusal’s status strings carry the basis.
