Struct HybridAtomCandidate 

pub struct HybridAtomCandidate {
    pub param: HybridAtomParam,
    pub negative_log_evidence: f64,
    pub num_parameters: usize,
    pub fitted_turning: Option<f64>,
}

One fitted candidate parameterization for a single hybrid-dictionary atom slot, scored on the COMMON rank-aware Laplace scale (−V = NLE, lower wins, identical to the union/mixture rungs). The curved and linear candidates for the SAME slot are fit on the same rows AND the same data (the atom’s response residual, #1202), so their NLEs are directly comparable; the structural difference is the curved candidate’s larger free-parameter price and whatever data-fit it buys with its curvature.

Fields

param: HybridAtomParam

negative_log_evidence: f64

Rank-aware Laplace negative-log-evidence on the common scale (lower wins).

num_parameters: usize

Free-parameter count this candidate is charged for (the complexity price).

fitted_turning: Option<f64>

The candidate’s fitted total turning Θ = ∫κ ds of its decoded curve, if the basis admits an analytic second jet. Some(0.0) for a linear atom (a straight image has no turning); None when the turning is honestly unavailable (no second jet / degenerate curve) — never fabricated.

Implementations

impl HybridAtomCandidate

pub fn linear(negative_log_evidence: f64, num_parameters: usize) -> Self

A linear special-case candidate: exact zero turning by construction.

pub fn curved( latent_dim: usize, negative_log_evidence: f64, num_parameters: usize, fitted_turning: Option<f64>, ) -> Self

A curved candidate of the given latent dimension, with its fitted turning.
