Struct QualityGate 

pub struct QualityGate { /* private fields */ }

Write quality gate that runs after A-MAC admission.

Constructed once and attached to crate::semantic::SemanticMemory via crate::semantic::SemanticMemory::with_quality_gate. Shared via Arc.

Fail-open

Any internal error (embed failure, LLM timeout, graph query error) is caught and treated as a pass. The gate never causes remember() to return an Err.

Implementations

impl QualityGate

pub fn new(config: QualityGateConfig) -> Self

Create a new quality gate with the given config.

pub fn with_llm_provider(self, provider: AnyProvider) -> Self

Attach an LLM provider for optional blended scoring.

pub fn with_graph_store(self, store: Arc<GraphStore>) -> Self

Attach a graph store for contradiction detection.

pub fn config(&self) -> &QualityGateConfig

Return a reference to the configuration.

pub fn rejection_counts(&self) -> HashMap<QualityRejectionReason, u64>

Return cumulative rejection counts per reason.

pub async fn evaluate( &self, content: &str, embed_provider: &AnyProvider, recent_embeddings: &[Vec<f32>], ) -> Option<QualityRejectionReason>

Evaluate the quality gate for a candidate write.

Returns None when the write passes (should be persisted). Returns Some(reason) when the write should be rejected.

Failures inside scoring are caught and treated as pass (fail-open).
