Enum ProvenanceLabel 

#[non_exhaustive]
pub enum ProvenanceLabel {
    External(ExternalKind),
    RecallReEntry,
    ModelDerived,
}

The provenance channel assigned to every write — required, typed, and immutable.

Provenance is set at injection time and cannot be changed after the claim is committed. It determines how the engine routes the claim through the adjudication gate. Model-emitted content must use ModelDerived — the ingestion gateway enforces this and callers cannot override it by supplying a more prestigious label.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

External(ExternalKind)

First-hand external evidence — the ONLY cheap-path-eligible channel.

RecallReEntry

Content the engine itself previously served, re-entering the write path. Caught by the Amplification Guard (firewall). Corroborates by identity; never becomes ground truth.

ModelDerived

Model-emitted / inferred content. The mandatory default for model output. Committed down-weighted (Inferred disposition); ineligible to overturn until anchored.

Implementations

impl ProvenanceLabel

pub fn is_cheap_path_eligible(&self) -> bool

Returns true iff this label is eligible for the cheap (non-conflicting commit) path. Only External(*) qualifies. RecallReEntry and ModelDerived never qualify.

pub fn is_recall_reentry(&self) -> bool

Returns true iff this is a RecallReEntry — must be caught by the Amplification Guard.

Trait Implementations

impl Clone for ProvenanceLabel

fn clone(&self) -> ProvenanceLabel

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ProvenanceLabel

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for ProvenanceLabel

fn deserialize<__D>( __deserializer: __D, ) -> Result<ProvenanceLabel, <__D as Deserializer<'de>>::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Eq for ProvenanceLabel

impl Hash for ProvenanceLabel

fn hash<__H>(&self, state: &mut __H)

where __H: Hasher,

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq for ProvenanceLabel

fn eq(&self, other: &ProvenanceLabel) -> 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 ProvenanceLabel

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
