Enum Additivity 

pub enum Additivity {
    Additive,
    SemiAdditive,
    NonAdditive,
}

Whether a metric’s aggregation is additive across the dimensions a decomposition would drill along. Inferred by an adapter from the metric’s underlying aggregation; it is not a field any current MDL carries.

• Additive — a sum-of-parts equals the whole (SUM, non-distinct COUNT).
• NonAdditive — parts do not sum to the whole (AVG, MIN, MAX, ratios, COUNT(DISTINCT …)).
• SemiAdditive — additive across some dimensions but not others (classically, not across time — balances, inventory levels). Forward-declared: warble classifies nothing itself — a producer reports the additivity it inferred — and the expression heuristics seen so far only distinguish additive vs non-additive, so this variant is defined but not yet observed.
