A regex literal embedding a quote desynced the string tokenizer and
swallowed an unconditional Result.YES, so the grant read as unscoped and
slipped past the literal-identity check. Fail closed on any slash outside
a string or comment; neither regex nor division belongs in an
identity-scoped grant.
