Function build_privileged_resolved 

pub fn build_privileged_resolved(
    owning_unit: &str,
    unit_tables: &HashMap<String, UnitTable>,
    unit_uses: &HashMap<String, Vec<String>>,
    unit_consumes: &HashMap<String, Vec<String>>,
    unit_consumes_aliases: &HashMap<String, HashMap<String, String>>,
) -> Option<(ResolvedCommons, ())>

Build a resolver::ResolvedCommons backed by owning_unit’s privileged view: its types, fns, methods, plus types/fns from every commons it uses, plus exported types from every consumed context. The same shape used by the production pipeline. Returns the ResolvedCommons plus a synthetic commons span for the test.
