The cross-branch agreement check ignored `const`, so two branches pinned to
`1` and `"1"` both stated no `type`, both matched the text `1`, and
the first one's typed constant was sent. Textually indistinguishable constants
of different types are ambiguous, and the raw string the user typed is the
honest answer.
