Struct EvidenceLedger 

pub struct EvidenceLedger { /* private fields */ }

A ledger of evidence explaining a match score.

This provides full transparency into why a match received its score, enabling debugging and user explanations.

Implementations

impl EvidenceLedger

pub fn new() -> Self

Create a new empty ledger.

pub fn add( &mut self, kind: EvidenceKind, bayes_factor: f64, description: EvidenceDescription, )

Add an evidence entry.

pub fn entries(&self) -> &[EvidenceEntry]

Get all entries.

pub fn combined_bayes_factor(&self) -> f64

Compute the combined Bayes factor (product of all factors).

pub fn prior_odds(&self) -> Option<f64>

Get the prior odds (from MatchType entry, if present).

pub fn posterior_probability(&self) -> f64

Compute posterior probability from prior odds and evidence.

posterior_prob = posterior_odds / (1 + posterior_odds) where posterior_odds = prior_odds × combined_bf

impl EvidenceLedger

pub fn to_jsonl(&self) -> String

Format this ledger as a JSONL line for structured logging.
