// A generic-struct ALIAS whose RHS is a qualified head (`ABox :: a.Box(s64)`)
// must make an ALIAS-typed receiver (`x: ABox`) a first-class dispatch instance:
// `x.tag()` runs the author `a`'s body with `a`'s bindings — never a dead end.
// Two namespaces author a same-name generic `Box($T)` with a DIFFERENT layout and
// a DIFFERENT `tag`; the alias over `a.Box(s64)` must dispatch `a.Box.tag`.
//
// Regression (Phase E4 Counter-2): the alias registration cloned the layout into
// a fresh type named `ABox` but did NOT mirror the instance template/bindings/
// author onto the alias name, so `x.tag()` on an `ABox` receiver resolved to
// nothing (unresolved). Copying the three instance-map entries to the alias name
// makes the alias receiver dispatch its author's method.
