A published bundle's JSDoc can name a type that only its .d.ts declares:
hono's bearerAuth carries `@template E` and `@returns {MiddlewareHandler<E>}`
without importing MiddlewareHandler. The checker types that result as its
error type, and a call of such a generic JavaScript function was refused
with SC2001 ("values of type 'MiddlewareHandler<E>' cannot be compiled").
The unresolved annotation is documentation, not a contract, so the call's
result is now checked-dynamic, as an `any` result of a TypeScript generic
already is.
