I have no idea what you're trying to do

doesn't seem like your Strict type does anything

it will always spit out the same type it recieved

i think they want it to error because "ERR_aaa" is not assignable to Uppercase<string>

i don't know zod very well but i think if anything this would be the way to do that:

Preview:```ts
import {z} from "zod"

z.object<Record<Uppercase<string>, string>>({
ERR_aaa: z.string(),
})```

however as you can see it doesn't work, because zod apparently constrains raw types to be keyed by string (using this type as the constraint: https://github.com/colinhacks/zod/blob/cfbc7b3f6714ced250dd4053822faf472bf1828e/src/types.ts#L48)

export type ZodRawShape = { [k: string]: ZodTypeAny };

i guess i really don't know zod very well. i'm not sure if this is exactly what you want, but it does work and maybe helps put you on the right path:
