Struct VersionedDecisionLedger 

pub struct VersionedDecisionLedger {
    pub schema_version: String,
    pub ledger_id: String,
    pub created_at_unix_ms: u128,
    pub last_updated_unix_ms: u128,
    pub record_count: usize,
    pub records: Vec<DecisionRecord>,
}

A decision ledger with explicit schema versioning for forward compatibility.

Use this struct when persisting ledgers to disk or transmitting over the wire. The schema version allows consumers to detect incompatible changes and migrate data appropriately.

Fields

schema_version: String

Schema version string (semver format)

ledger_id: String

Ledger identifier for tracking

created_at_unix_ms: u128

Unix timestamp when ledger was created (milliseconds)

last_updated_unix_ms: u128

Unix timestamp of most recent record (milliseconds)

record_count: usize

Total number of records

records: Vec<DecisionRecord>

The decision records
