Function infer_participants 

pub fn infer_participants(
    target: &str,
    unit_consumes: &HashMap<String, Vec<String>>,
) -> Vec<String>

v0.118: infer a system-tier suite’s wired participants — the target’s transitive consumes closure (testing track slice 6). A BFS from the target following consumes edges; the returned list starts with the target and includes every context reachable through it (deterministic breadth order).
