Struct RetrievalFailuresConfig 

pub struct RetrievalFailuresConfig {
    pub enabled: bool,
    pub low_confidence_threshold: f32,
    pub retention_days: u32,
    pub channel_capacity: usize,
    pub batch_size: usize,
    pub flush_interval_ms: u64,
}

OmniMem retrieval failure tracking configuration (issue #3576).

Controls the async logger that records no-hit and low-confidence recall events to memory_retrieval_failures for closed-loop memory parameter tuning.

Fields

enabled: bool

Enable retrieval failure logging. Default: false.

low_confidence_threshold: f32

Composite recall score below which a result is classified as low-confidence.

The threshold applies to the post-reranking composite score (which incorporates MMR, temporal decay, importance weighting, and tier boost). Calibrate against the scoring pipeline in use. Default: 0.3.

retention_days: u32

Days to retain failure records before automatic cleanup. Default: 90.

channel_capacity: usize

Bounded mpsc channel capacity for the fire-and-forget write path. Default: 256.

batch_size: usize

Maximum records collected before flushing a batch INSERT. Default: 16.

flush_interval_ms: u64

Maximum milliseconds to wait before flushing a partial batch. Default: 100.
