Compose a field's cross-service chain over strand edges.
EXPERIMENTAL. Walk connected strand edges from one (component, payload, field) start state — upstream toward the fields the start field comes from (the default), or downstream toward the fields it flows to — and return every traversal branch: CONNECTED chains with their terminal group, UNMAPPED_HOP branches where a translated path nothing on the landing side exposes ends the walk visibly, and CYCLE branches where a traversal state repeats on its own path. Every involved component is evaluated at its latest scan; a traversal that would cross a composition contract limit fails as a typed error rather than returning a partial graph.

Path Parameters
UUID of the component the walk starts on.
Query Parameters
The payload_name coordinate of the start payload group on the component.
The field to trace, as a dot-separated path.
Traversal direction. Upstream walks toward the fields the start field comes from; downstream walks toward the fields it flows to.
Available options:
upstream, downstream Response
Every traversal branch from the start state.
Every branch of walking connected strand edges upstream from one (component, payload, field) start state. Branches are complete — a traversal that would cross a contract limit fails as a typed error rather than returning a partial graph.
