All properties are NOT required by default on inferred type

I am following the README, at this point

https://github.com/colinhacks/zod#objects

an example is provided stating that “all properties are required by default”, but when inspecting the inferred types I see that all properties are optional instead.

Minimal reproducible example (zod v 3.11.6) https://stackblitz.com/edit/react-ts-eihrxu

Hover on line 18 on DogType

I can see the inferred type as:

type DogType = {
    name?: string;
    age?: number;
}

when instead, accordingly to the doc should be:

type DogType = {
    name: string;
    age: number;
}

Questions:

• Is the document correct/updated?
• How to make sure the properties are not inferred as optional? If you would provide a working sample I would appreciate it

Thanks for your time and great work on zod!
