Function assembly_resolve_refs_json 

pub fn assembly_resolve_refs_json(refs_json: &str) -> String

Resolve selection refs against the live session WITHOUT touching any constraint: refs_json is ["ACOMP2:Part_PZ", …]; the reply is one row per ref, {ref, ok: true, component, geom, point, direction, radius} in the owning component’s local frame, or {ref, ok: false, status, error}. Read-only — the replace-component lane snapshots a mate’s references before the swap with it.
