Enum SpanPlan 

pub enum SpanPlan {
    Resolved(Option<Pos>),
    Sources(Vec<SpanSource>),
    Opaque,
}

One endpoint of a transform-mode raw-children span scan.

Variants

Resolved(Option<Pos>)

Engine-decided: Some = the contributing group, None = every raw child skips (lark leaves the endpoint unset).

Sources(Vec<SpanSource>)

Candidates to walk at resolution, first contribution wins.

Opaque

Blocked by an opaque Foreign (synchronous-hook value): undecidable forever — resolves to the Meta::Poisoned residual.
