🧑‍💻 Repro

type.fn.raw is always undefined, but exists at the type-level (typed as a function):

import { type } from "arktype"

type.fn.raw() // throws type.fn.raw is not a function
//      ^? FnParser<{}>.raw: (...args: unknown[]) => (...args: unknown[]) => unknown
//         An alias of fn with no type-level validation or inference.
//         Useful when wrapping fn or using it to parse a dynamic definition.
