Struct ThresholdLearner 

pub struct ThresholdLearner {
    pub per_ext: HashMap<String, LearnedDelta>,
    pub schema_version: u32,
}

Fields

per_ext: HashMap<String, LearnedDelta>

Keyed by lowercase extension without dot (e.g. “rs”).

schema_version: u32

Implementations

impl ThresholdLearner

pub fn merge_from(&mut self, other: &Self)

Team-merge (#550): sample-weighted average of deltas, never a blind overwrite. samples = max(...) (not the sum) and weighted-mean deltas make re-importing the same bundle a no-op (idempotent roundtrip) and prevent double counting. Clamps stay authoritative.

pub fn record(&mut self, ext: &str, signal: QualitySignal, now: u64)

Apply one quality signal for ext at now (unix seconds).

pub fn delta_for(&mut self, ext: &str, now: u64) -> f64

Additive entropy-threshold delta for ext, or 0.0 before MIN_SAMPLES.

pub fn report_lines(&self) -> Vec<String>

One line per learned extension, for ctx_metrics.
