Struct Provenance 

pub struct Provenance {
    pub actor: Did,
    pub timestamp: String,
    pub action_hash: Vec<u8>,
    pub signature: Vec<u8>,
    pub public_key: Option<Vec<u8>>,
    pub voice_kind: Option<VoiceKind>,
    pub independence: Option<IndependenceClaim>,
    pub review_order: Option<ReviewOrder>,
}

Provenance metadata for an action.

Fields

actor: Did

timestamp: String

action_hash: Vec<u8>

signature: Vec<u8>

public_key: Option<Vec<u8>>

Ed25519 public key (32 bytes) of the actor.

check_provenance_verifiable requires this key and performs Ed25519 signature verification over the domain-separated canonical CBOR provenance payload. Provenance without this key fails closed.

voice_kind: Option<VoiceKind>

Whether this actor is human, synthetic (AI), or a system process.

Governance surfaces accepting plural input MUST use this field to prevent synthetic voices from counting as distinct humans (CR-001 §8.3).

independence: Option<IndependenceClaim>

Whether the actor claims to act independently (no undisclosed common control with other reviewers or voters).

review_order: Option<ReviewOrder>

Whether this is a first-order review or derivative (echo/summary).

Implementations

impl Provenance

pub fn is_signed(&self) -> bool

pub fn is_human_voice(&self) -> bool

Returns true when provenance explicitly identifies this as a human voice. None (unspecified) returns false — unattributed provenance is never assumed to be authentic human judgment.

pub fn is_independent(&self) -> bool

Returns true when provenance explicitly claims independence. None (unspecified) is treated as non-independent.

pub fn is_first_order_review(&self) -> bool

Returns true when this provenance is explicitly first-order review. None and derivative review are not equivalent to direct human review.

pub fn is_authentic_human_quorum_voice(&self) -> bool

Returns true when all taxonomy fields required for a human quorum claim are present and explicit. Cryptographic verification is performed by the invariant engine because it needs trusted DID-resolved keys.

pub fn is_synthetic(&self) -> bool

Returns true when this is explicitly a synthetic (AI-generated) voice.

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 Eq for Provenance

impl PartialEq for Provenance

fn eq(&self, other: &Provenance) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

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.
