In my opinion TDD is antithetical to this process.

The primary reason is because what you are rapidly refactoring in these early prototypes/revisions are the meta structure and the contacts.

Before AI the cost of putting tests on from the beginning or TTD slowed your iteration speed dramatically.

In the early prototypes what you are figuring out is the actual shape of the problem and what the best division of responsibilities and how to fit them together to fit the vision for how the code will be required to evolve.

Now with AI, you can let the AI build test harnesses at little velocity cost, but TDD is still not the general approach.
