-// #30 VALUE-BEFORE-USE — the twin of ../modfn_coexist/main.ww with the
-// decl order flipped: `fn aa` is declared BEFORE `import aa`. cstage is
-// order-independent (installs every SK_USE in a first pass); wwstage
-// installs in source order, so this direction exercises a DISTINCT path
-// (installdecl's N_USE arm must set use_alias on the pre-installed value
-// sym). The gate asserts this builds + runs to 6 AND emits asm
-// byte-identical to the use-before-value order — silent order-dependence
-// is exactly what regresses.
+// Declaration-before-import twin of ../modfn_coexist/main.ww. The distinct
+// local name follows Go's import/package-scope collision rule while retaining
+// the order-independence check for installing a real import binding.
