It's a mix of personal scars and peer review.

Experience: I draw primarily from 14 years in product companies, focusing on the specific friction points where I've seen Leads struggle (or where I struggled myself).

Vetting: I stress-test the dialogue options with a network of Engineering Managers and Directors to ensure the 'winning' paths reflect reality, not just theory.

That said, unlike C++, management doesn't have a compiler to prove you are 'Correct.' It is subjective. The feedback in this thread is actually highlighting some edge cases I missed, which helps me refine the grading logic
