The chained value-struct walker's N_CALL arm handled only <=24B register returns; an sret-class rhs fell to the scalar tail and stored ONE word (the sret dest pointer) into the leaf -- silent truncation in BOTH stages, byteid-blind. Point the callee's hidden RDI at the BP-relative leaf slot (the single-dot #234 arm verbatim); a ptr-root/global chain joins the #234-tail loud-stop family.
