Arena
When one shot at a non-trivial artifact would lock you into the wrong shape, spawn three or more parallel candidates with the same prompt, score them against a concrete rubric, pick the cleanest as your base, then graft the best ideas from the losers. The protocol is strict about framing the rubric up front, reading every candidate end to end before picking, and recording what you rejected so future readers learn from the alternatives you considered. It fights the bias toward whichever surface looks most familiar and forces you to judge on extension points and maintainability instead of holistic feel. The verification phase at the end reminds you the arena doesn't earn you a pass on proving it works.
