Struct TraverseSpec 

pub struct TraverseSpec {
    pub path: Option<String>,
    pub on_missing: OnMissing,
}

traverse: — knobs on the result-traversal layer.

The layer itself is always installed (result: and metrics: declare it as requires_inner, and the composition resolver enforces that at init), so this block only tunes behaviour that is otherwise fixed.

Fields

path: Option<String>

Base JSON Pointer (RFC 6901) applied to the result body BEFORE any capture is resolved, re-rooting the document.

Every capture otherwise repeats the same prefix — /value/0/x, /value/0/y — which is the shape envelope responses force ({value, status, …}). poll.json_path already exists for exactly this reason on exactly this data; this is the same idea for captures.

on_missing: OnMissing

What to do when a declared capture resolves to nothing.
