Struct PreFeaturized 

pub struct PreFeaturized {
    pub tree: PatchTree,
    pub cached: CachedFeatures,
    pub audition: Option<Arc<Audition>>,
}

A candidate whose render, vetting and featurization already happened — in a farm worker, or on the way back from transport.

It carries exactly what auracle_features::featurize_memo produces, minus the work: the term, its CachedFeatures (content key, raw φ, vet report, onsets, length), and optionally the audition buffer. The engine folds one of these in with crate::Engine::absorb_prior or crate::Engine::absorb_bank_entry, which apply the same dedupe, standardization and admission rules the in-process path applies.

A failed vet has no PreFeaturized: it is None at the absorb site, which is how a quarantined draw stays a normal outcome rather than an error.

Fields

tree: PatchTree

The term.

cached: CachedFeatures

Everything the featurization produced except the samples.

audition: Option<Arc<Audition>>

The audition buffer, when the producer was asked for one and it survived transport. Absent is never a failure signal — φ is the product, audio is the option.

Implementations

impl PreFeaturized

pub fn render( tree: PatchTree, spec: &PhraseSpec, want_audio: bool, ) -> Result<Self, FeaturizeError>

Render, vet and featurize one term without an crate::Engine — the farm worker’s entire job.

Deliberately unmemoized: a farm worker is a pure function of its arguments and holds no state between jobs, which is what lets the engine treat any worker as interchangeable with any other (and with itself).
