Struct Provenance 

pub struct Provenance {

    pub produced_by: String,
    pub model_version: String,
    pub payload_mode_used: PayloadMode,
    pub confidence: Option<f64>,
    pub verified: bool,
    pub session_id: Option<String>,
    pub timestamp: Option<String>,
    pub tokens_used: Option<u64>,
    pub cost_usd: Option<f64>,
    pub contract_id: Option<String>,
    pub contract_satisfied: Option<bool>,
    pub contract_violations: Vec<String>,
    pub verification_status: VerificationStatus,
    pub evidence: Vec<EvidenceRef>,
    pub lineage: Vec<ProvenanceEntry>,
}

Provenance metadata attached to every LDP task result.

Embedded in the output Value so it flows through JamJet’s existing pipeline without modification.

Fields

produced_by: String

Delegate ID that produced this result.

model_version: String

Model version used.

payload_mode_used: PayloadMode

Payload mode used for this exchange.

confidence: Option<f64>

Self-reported confidence (0.0 – 1.0).

verified: bool

👎Deprecated:

Use verification_status instead

Whether the result has been verified (e.g. by a second delegate).

session_id: Option<String>

Session ID in which this result was produced.

timestamp: Option<String>

Timestamp of production.

tokens_used: Option<u64>

Tokens consumed by the delegate (delegate-reported).

cost_usd: Option<f64>

Cost incurred in USD (delegate-reported).

contract_id: Option<String>

Contract ID this result was produced under.

contract_satisfied: Option<bool>

Whether the contract was satisfied (set by client-side validation).

contract_violations: Vec<String>

List of contract violation codes (set by client-side validation).

verification_status: VerificationStatus

Granular verification status.

evidence: Vec<EvidenceRef>

Supporting evidence references.

lineage: Vec<ProvenanceEntry>

Delegation lineage chain (newest hop first).

Implementations

impl Provenance

pub fn new( delegate_id: impl Into<String>, model_version: impl Into<String>, ) -> Self

Create a new provenance record.

pub fn normalize(&mut self)

Sync verified bool with verification_status. verification_status is authoritative.

pub fn to_value(&self) -> Value

Convert to a JSON Value for embedding in task output.

Trait Implementations

impl Clone for Provenance

fn clone(&self) -> Provenance

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Provenance

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for Provenance

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Serialize for Provenance

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
