Struct UnifiedEvidenceLedger 

pub struct UnifiedEvidenceLedger { /* private fields */ }

Fixed-capacity ring buffer storing EvidenceEntry records from all decision domains.

Pre-allocates all storage so that record never allocates on the hot path.

Implementations

impl UnifiedEvidenceLedger

pub fn new(capacity: usize) -> Self

Create a new ledger with the given capacity.

pub fn record(&mut self, entry: EvidenceEntry) -> u64

Record an evidence entry. Overwrites oldest when full.

Returns the assigned decision_id.

pub fn len(&self) -> usize

Number of entries currently stored.

pub fn is_empty(&self) -> bool

Whether the ledger is empty.

pub fn total_recorded(&self) -> u64

Total entries ever recorded (including overwritten).

pub fn domain_count(&self, domain: DecisionDomain) -> u64

Number of decisions recorded for a specific domain.

pub fn entries(&self) -> impl Iterator<Item = &EvidenceEntry>

Iterate over stored entries in insertion order (oldest first).

pub fn entries_for_domain( &self, domain: DecisionDomain, ) -> impl Iterator<Item = &EvidenceEntry>

Get entries for a specific domain.

pub fn last_entry(&self) -> Option<&EvidenceEntry>

Get the most recent entry.

pub fn last_entry_for_domain( &self, domain: DecisionDomain, ) -> Option<&EvidenceEntry>

Get the most recent entry for a specific domain.

pub fn export_jsonl(&self) -> String

Export all entries as JSONL.

pub fn flush_to_sink(&self, sink: &EvidenceSink) -> Result<()>

Flush entries to an evidence sink.

pub fn clear(&mut self)

Clear all stored entries. Domain counters are preserved.

pub fn summary(&self) -> LedgerSummary

Summary statistics per domain.
