pub const RELATIVE: f64 = 0.5;Expand description
An early delivery takes lessons scoring at least this share of the best on-topic match (early).
Baseline: today’s early rule (R3b, internal evaluation “phase-r”), kept until a learned early rule
is fitted on the share each early delivery’s record carries per lesson (outcome.rs rel, hook.rs
early_rel; empty when no plain lesson was on topic). Those records hold only delivered lessons, and
every plain one scored at least this bar, so a rule fitted on them alone can learn to raise it, not
what a lower bar would admit.
