How quality is controlled — and the failure that made it necessary.

If agents make your product, agent mistakes ARE your product — unless something stands in the way. This system learned that with a number: in one early batch, 62% of the generated pictures were missing the greeting text they were supposed to carry. Pretty, useless, and almost shipped. The answer was a dedicated QA agent with a simple creed: check a fair sample of everything, score each piece on explicit criteria, let a judge integrate the scores — but enforce the cultural and safety line in plain code, and keep a human able to overrule everything.
