Struct EntryTouchFold 

pub struct EntryTouchFold {
    pub per_token: BTreeMap<Token, BTreeSet<u32>>,
}

Accumulates the set of tree-node file ordinals a token’s reads have touched: the UNION of every event’s crate::Event::entry. Union is commutative and idempotent — like the OR in RegionTouchFold — so R-1/R-3 (order- and duplicate-tolerance) and C-8 hold for free. Tree coverage evaluates |touched ∩ [0, node.files)| against each node’s signed directory index for a true per-file receipt.

Fields

per_token: BTreeMap<Token, BTreeSet<u32>>

Token → the set of DirIndex file ordinals its reads have reached.
