// G1 (non-struct kind = error-set) — a qualified `a.IoErr` annotation selects the
// namespace target's OWN error-set per-decl nominal, distinct from `main`'s
// same-name `IoErr`. `main` authors `IoErr { Disk }` and namespace-imports `a`
// (`IoErr { Net }`). The bare `IoErr` binds main's own (so `error.Disk` is valid);
// the qualified `a.IoErr` binds `a`'s (so `error.Net` is valid). The tag sets are
// disjoint, so a cross-binding (`a.IoErr = error.Disk`) is a hard membership error
// — distinct error-set nominals reached through the qualified annotation surface.
