Enum FeatureId 

pub enum FeatureId {
    EditDistance1,
    EditDistance2,
    TokenReorder,
    SupersededToken,
    BaseRateCommonMarking,
    StrictContextClassification,
    CorpusOverrideInEffect,
}

Closed enumeration of features the decoder can record.

New variants MUST bump the audit schema version (see MARQUE_AUDIT_SCHEMA in crates/engine/build.rs). Treat this enum as part of the on-the-wire audit contract.

Variants

EditDistance1

Observed form is edit-distance 1 from a canonical token.

EditDistance2

Observed form is edit-distance 2 from a canonical token.

TokenReorder

Observed form is a token-order permutation of a canonical banner/portion shape.

SupersededToken

Observed form is a known CAPCO-2016-superseded token whose replacement is unambiguous (e.g., COMINT → SI).

BaseRateCommonMarking

The candidate’s base rate in the target corpus dominates the posterior (common-marking prior).

StrictContextClassification

Strict-context classification floor (FR-011) applied — e.g., banner at TOP SECRET forces a strict posterior for classification tokens at ≥ that level on the same page.

CorpusOverrideInEffect

Corpus-override data (opt-in, non-WASM, non-server) shifted the posterior. Recorded so an auditor can identify fixes produced under organizational overrides vs. stock priors.

Implementations

impl FeatureId

pub const fn as_str(self) -> &'static str

Canonical on-the-wire string label for this feature.

This is the single source of truth for FeatureId → audit-record-string projection. Audit emitters (CLI, WASM, server) and snapshot tests MUST call this method rather than re-implementing the match. A new FeatureId variant added without a matching as_str arm fails the exhaustiveness check here at compile time, so the on-the-wire contract cannot drift silently across emitters.

Returns a &'static str so callers can embed the value in zero-copy serialization paths (Serialize derives, serde_json::json! etc.) without an allocation.

Trait Implementations

impl Clone for FeatureId

fn clone(&self) -> FeatureId

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for FeatureId

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

Formats the value using the given formatter.

impl Hash for FeatureId

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

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 FeatureId

fn eq(&self, other: &FeatureId) -> 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.
