Assumption Testing Prompt

Find the unverified assumptions quietly undermining your plan

Look over this problem — [problem] — and pull out every assumption baked into it, whether I've said it outright or just implied it. Sort each assumption into validated, uncertain, risky, or flat-out wrong. For anything uncertain, suggest a quick experiment, test, or bit of research that would actually confirm or kill it. Then rebuild the solution using only the assumptions that would survive that scrutiny.
