Struct ResearchDecisionLedger 

pub struct ResearchDecisionLedger { /* private fields */ }

Immutable canonical/integration history across all contexts of one container.

Implementations

impl ResearchDecisionLedger

pub fn batch(&self) -> Result<RecordBatch, KnowledgeError>

Encode complete current history as native Arrow.

pub fn from_batches(batches: &[RecordBatch]) -> Result<Self, KnowledgeError>

Decode complete history; filtered views are not valid publication ledgers.

pub fn new(events: Vec<ResearchDecisionRecord>) -> Result<Self, KnowledgeError>

Validate complete history; a missing ordinal is corruption, not expiry.

pub fn append( &self, staged: Vec<ResearchDecisionRecord>, ) -> Result<Self, KnowledgeError>

Append exact records or return an unchanged ledger on exact event replay.

pub fn events(&self) -> &[ResearchDecisionRecord]

Inspect all history, including introduction and revoked decisions.

pub fn canonical_decision( &self, authority: &ResearchAuthority, subject_kind: ResearchSubjectKind, subject_uuid: Uuid, ) -> Option<&ResearchDecisionRecord>

Latest explicit canonical decision only in the exact requested authority. An integration event, source context, or different community cannot grant it.
