get_axis sits beside get_var as a plain dict lookup over a projection build_resolve_ctx makes at frame construction, so the resolver stays a pure consumer with no ctx dependency. Keyed by binding, matching what the reference addresses. Branches before the var lookup: $outfit.SHOES must resolve even when nothing bound $outfit itself, and must not trip unknown_var on the way past. Never routes through deref_var_value either - an axis value is not a ListVar, so the SP2a accessor contract is untouched. A missing axis renders empty and warns unknown_tag_axis rather than failing, matching how every other unresolvable reference behaves.
