Struct MatchConfidence

    pub runner_up_motif: Option<MotifClass>,

Confidence-bearing motif match result.

Returned by HeuristicsBank::match_episode_with_confidence. The margin field is (top_score - runner_up_score) / top_score, clamped to [0.0, 1.0]. Operators reading the margin can calibrate trust:

• margin > 0.5 → top motif clearly dominates; act on it
• margin in (0.2, 0.5] → moderate confidence; surface runner-up
• margin <= 0.2 → top and runner-up are competitive; surface both
• top_score == 0.0 → no motif matched (disposition == Unknown)

Fields

disposition: SemanticDisposition

top_score: f64

runner_up_score: f64

runner_up_motif: Option<MotifClass>

margin: f64

tier_consensus_factor: f64

Phase 3 — fraction of the matched motif’s affinity tiers that actually fired in the episode range, in [0, 1]. Populated only by match_episode_with_tier_affinity; the legacy match_episode_with_consensus leaves this at 0.0. Used by the adaptive margin gate (Path 3): when tier_consensus_factor > 0.5, the gate is halved — strong tier evidence justifies lower margin requirement.

confuser_motif: Option<MotifClass>

Phase 5.6 — explicit confuser motif declared by the matched motif’s HeuristicEntry. May differ from runner_up_motif if the score-based runner-up is not the declared confuser. None when no confuser is declared.

confuser_score: f64

Phase 5.6 — score of the declared confuser computed in the same scoring pass as the matched motif. 0.0 if no confuser is declared.

margin_vs_confuser: f64

Phase 5.6 — margin of top motif over its declared confuser: (top_score - confuser_score) / top_score, clamped to [0, 1]. Used by fusion’s confuser-aware typed-confirmation gate. 0.0 if no confuser is declared.

Trait Implementations

impl Clone for MatchConfidence

fn clone(&self) -> MatchConfidence

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for MatchConfidence

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl PartialEq for MatchConfidence

fn eq(&self, other: &MatchConfidence) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
