Struct RuntimeCoverageDiscriminators 

pub struct RuntimeCoverageDiscriminators {
    pub tracking_state: String,
    pub invocation_ratio: Option<f64>,
    pub low_traffic_threshold: f64,
    pub trace_count: u64,
    pub min_observation_volume: u32,
    pub meets_observation_volume: bool,
}

Discriminator inputs that PRODUCED a finding’s verdict, emitted alongside the verdict so an agent can reproduce it and see the minimum-observation confidence cap instead of re-deriving them from scratch. F4: these make the EXISTING Fallow-owned discriminators legible; they are not a new or external signal and gate nothing. Pairs with evidence.static_status (the static half of the discriminator set).

Fields

tracking_state: String

Three-state runtime tracking: called (invocations > 0), never_called (V8 tracked it, invocations == 0), or untracked (V8 never saw it). The ONLY signal that can issue a deletion verdict.

invocation_ratio: Option<f64>

invocations / trace_count for this function; null when untracked (no invocation count). The per-function value behind the low-traffic split.

low_traffic_threshold: f64

Active/low_traffic split ratio in effect (CLI default 0.001). A tracked function whose invocation_ratio is below this reads low_traffic, else active.

trace_count: u64

Total observed invocations across all functions (the invocation_ratio denominator), echoed per finding so the verdict is self-contained.

min_observation_volume: u32

High-confidence verdict floor (CLI default 5000). When trace_count is below it, confidence is capped regardless of the per-function signal.

meets_observation_volume: bool

trace_count >= min_observation_volume: whether the dump cleared the confidence floor. false means this verdict’s confidence is capped.
