Struct RegionTouchFold 

pub struct RegionTouchFold {
    pub per_token: BTreeMap<Token, u8>,
}

Accumulates contract region touches per token: the OR of every event’s regions bitmask (doc 19 §4.2). Commutative and duplicate-tolerant by construction — OR is both — so R-1/R-3 hold without ceremony. coverage evaluates this against the manifest’s declared crate::Contract.

Fields

per_token: BTreeMap<Token, u8>

Token → OR of region-touch bits observed so far.
