Enum Predicate 

pub enum Predicate {
    KeyMatch {
        field: String,
    },
    FieldEqual {
        field: String,
    },
    Overlap {
        field: String,
        min: f64,
    },
    All(Vec<Predicate>),
    NumericWithin {
        field: String,
        tolerance: f64,
    },
    GeoRadius {
        field: String,
        km: f64,
    },
    VectorSimilar {
        field: String,
        min: f64,
    },
    Any(Vec<Predicate>),
}

Score-combination conventions for composed predicates:

• All(parts) — minimum of the individual branch scores. Every branch must match; the weakest link controls the edge weight. Verified by test all_takes_min_score_and_requires_every_part.

• Any(parts) — maximum of the satisfied branches’ scores. At least one branch must match; the strongest match controls the edge weight. Verified by test any_score_is_max_when_both_branches_match.

These conventions are opposites: All is pessimistic (min), Any is optimistic (max). Nesting is allowed up to depth MAX_PREDICATE_NESTING_DEPTH; validate() returns a named error beyond that.
