-Outer setup variables use semantic names (`snap`, `user`) so `want`/`got` stay free.
+When a test uses if-init bindings on fresh expressions, outer setup variables must use semantic names (`snap`, `user`) so `want`/`got` stay free for those bindings. When all sides are captured at top level (no if-init `want`/`got`), the setup may be named `want` and the captured return `got`: the pair maps directly to the `want: ...; got: ...` format.
 
 For multi-value returns (`value, ok := m[k]`), capture both and split each failure mode into its own `if`. Use `t.Fatal` on the `ok` check when a follow-up value comparison depends on presence.
