Enum PathSupport 

pub enum PathSupport {
    Empty,
    Edge(Triple),
    Chain(Vec<PathSupport>),
    Alt(Vec<PathSupport>),
}

One concrete positive certificate that a node is a π-successor of its parent. Every Edge is present in the evaluation graph.

This is deliberately not a complete deletion cut: an alternative or cyclic path may have additional routes that are not represented here.

Variants

Empty

Reflexive (Id): the node reached itself; nothing to cut.

Edge(Triple)

A single triple edge used by this certificate.

Chain(Vec<PathSupport>)

A chain (Seq/Star expansion) used by this certificate.

Alt(Vec<PathSupport>)

Multiple certificate branches when a caller explicitly retains them. The current path fold is allowed to return only the first successful syntactic alternative.
