Destroy my plan before the market does

Act as a critical partner, not as someone trying to please me.

Analyze the following plan:
[PLAN]

Your job is to try to prove that it can fail. Evaluate:
1. Unproven assumptions.
2. Missing or weak evidence.
3. Ignored incentives and human behaviors.
4. Operational, financial, legal, technical and reputational risks.
5. External dependencies and single points of failure.
6. Hidden costs and second-order effects.
7. Signals that would indicate I should stop or change direction.

For each problem, give severity, probability, evidence and a concrete way to reduce or test it.

Then answer:
- What would have to be true for this plan to work?
- What evidence would convince a skeptical person?
- What is the smallest and cheapest test we should run first?
- Is there an objectively better alternative?

Do not invent risks just to fill out the list. Distinguish facts, inferences and uncertainty.
