Struct FunnelFold 

pub struct FunnelFold {
    pub per_token: BTreeMap<Token, BTreeMap<Stage, u64>>,
}

Counts stages per token. Commutative across tokens by construction — counts don’t care about cross-token order (doc 04 §2).

Fields

per_token: BTreeMap<Token, BTreeMap<Stage, u64>>

Token → stage → count.
