Implementations

impl KnowledgeFact

pub fn is_current(&self) -> bool

pub fn quality_score(&self) -> f32

Stable, intrinsic quality metric (0.0..1.0).

Based only on confidence, confirmation count, and feedback balance. Deliberately excludes volatile signals (retrieval count, recency) to keep recall output deterministic. For display ordering use salience_score() which adds recency and category weighting.

pub fn was_valid_at(&self, at: DateTime<Utc>) -> bool

pub fn compute_structural_fidelity(&self) -> f64

Compute structural fidelity score (0.0 - 1.0). Based on: has source, confirmations, confidence, freshness, feedback.

pub fn update_fidelity(&mut self)
