7## How to Help

91. **Clarify the Core Hypothesis** - Help the user define the specific problem, target audience, and the most 'risky' assumptions using the Founding Hypothesis Scorecard.
102. **Select a Validation Path** - Guide the user through choosing between the 'Listening Path', 'Manual Path', or 'Self-Serve Path' based on their proximity to the problem.
113. **Design Low-Fidelity Experiments** - Recommend specific 'Wizard of Oz' or 'Fake Door' tests to simulate the solution without building a backend.
124. **Evaluate Signal Quality** - Help users distinguish between polite interest and real market pull by looking for financial commitment or high-effort usage.
