Your synthetic CISO just approved your non-compliant tool.
That's not validation. That's sycophancy.
LLMs want to agree with you. Pitch hard enough, they'll validate anything.

A DevTools startup's synthetic VPs hated their $2k/month flat fee. Founders didn't believe it.
Then 4 out of 5 real VPs said the same thing: "I can swipe $500 for usage. I can't justify $24k/year for a test."
They pivoted pricing before writing billing code.
