Beyond Smarter Models: Why Structural Constraints Matter More Than AI Intelligence for Trustworthy Code

As AI generates most production code, the critical bottleneck shifts from model capability to code verification. Behavioral constraints in prompts and reviews fail at scale—access control and security rules slip through because they depend on agents remembering invariants. Structural gates that embed verification into the code's substrate itself provide the real safety guarantee, making buggy code architecturally impossible rather than hoping models remember the rules.
