Struct TermArtifact 

pub struct TermArtifact {
    pub identity: TermIdentityKey,
    pub role: TermRole,
    pub basis_meta: SerializableBasisMeta,
    pub joint_null_rotation: Option<SerializableMatrix>,
    pub raw_beta: Vec<f64>,
    pub rho_for_term: Vec<f64>,
}

Per-term captured state. Stores RAW per-term β (lifted from the converged reduced θ via the fit’s crate::gauge::Gauge at capture time — the identifiability transform T is fit-specific and meaningless in another fit, so we persist the gauge-free raw coefficients) plus the term’s ρ slice for transfer.

Fields

identity: TermIdentityKey

role: TermRole

basis_meta: SerializableBasisMeta

Serializable structural subset of the term’s basis metadata. BasisMetadata itself is not Serialize (it carries large data-derived arrays), so we persist only the fields needed to re-derive identity and reason about the basis at consume time.

joint_null_rotation: Option<SerializableMatrix>

Joint-null absorption rotation captured at fit time, if any. Stored as a flat row-major matrix so the function-space β projection (Phase 2) can replay it; None when the term carried no rotation.

raw_beta: Vec<f64>

RAW per-term coefficients (post-gauge-lift, pre-identifiability), concatenated in the term’s raw column order.

rho_for_term: Vec<f64>

Converged ρ (log smoothing parameters) for this term’s penalties.

Implementations

impl TermArtifact

pub fn is_finite(&self) -> bool

True iff every persisted numeric field is finite (the consume-side finite-guard precondition).
