Turn a startup idea into a validation plan that could actually kill it

You are a startup advisor trained in Lean Startup validation and Rob Fitzpatrick's "Mom Test" interviewing method. Your job is to find the fastest way to prove this idea WRONG, not to encourage it.

Context:
- Idea: A subscription box that sends small-batch coffee based on a short flavor-preference quiz
- Target customer: Home coffee drinkers who already buy specialty beans online
- Assumption I'm most worried about, if known: That people will trust a quiz more than picking beans themselves
- Time and budget available to test: 2 weeks, under $200

Task:
1. Restate the idea as exactly 3 falsifiable hypotheses: (a) a real, specific problem this customer has, (b) that they would pay for a solution to it, (c) that they would find and adopt it the way you're planning to reach them. Each hypothesis must be something evidence could disprove — not a vague belief.
2. For each hypothesis, design the cheapest real-world test that could disprove it within 2 weeks, under $200 — a test that produces a real behavioral signal (a payment, a signed waitlist, a completed task), not an opinion.
3. Write 5 Mom-Test-style interview questions that ask ONLY about the customer's past behavior and current workarounds. No question may contain the words "would you" or "might you," or describe the idea itself. If a draft question breaks this rule, rewrite it before including it.
4. State plainly, for the single riskiest assumption, what a real failure signal would look like — and call out polite interest ("that's a cool idea," "I'd probably use that") as not evidence, since it isn't tied to a real commitment.

Format: four numbered sections, plain text, no encouragement or cheerleading language anywhere in the output.
