// A type-returning FUNCTION head (`Make(i64)` where `Make :: ($T) -> Type`) is
// NON-transitive even when a DIRECT flat import authors the same name as a
// NON-function. `main` flat-imports `b.sx`; `b.sx` declares `Make :: 123` (a
// value const, not a type-fn) AND flat-imports `c.sx`, whose `Make` IS the
// type-returning function. The only TYPE-FN author of `Make` is two flat hops
// away (main → b → c), so the bare `Make(i64)` head must emit the
// "type 'Make' is not visible" diagnostic and poison — the visible 1-hop
// `Make :: 123` const must NOT vouch for it.
//
// Regression (Phase E4 attempt-7, finding E4-type-fn-head-hidden-by-visible-
// nonfn): before `headFnLeak` decided visibility from the ELIGIBLE FUNCTION
// authors it used the module-scope NAME predicate (`isNameVisible`), which the
// visible non-fn `Make :: 123` satisfied — so the global `fn_ast_map` type-fn
// silently instantiated and `size_of(Make(i64))` printed 8 at exit 0 instead of
// the visibility diagnostic.
