Attacks the load-bearing assumption under a market consensus before you build a year toward someone else's truth.
Tests a market-wide consensus against your specific case instead of producing a balanced memo. It surfaces the single load-bearing assumption, gives you a cheap, fast signal that would break it, and quantifies the cost of being wrong each way. One assumption, one test, one verdict — before you spend a year building toward someone else's truth.

Operator stress-testing a category "best practice" before the team commits a quarter to building toward it.
