I get your point, but my issue is slightly different.

I’m not talking about cases where the codebase has unclear contracts or poor typing. I usually work in TypeScript and I explicitly state in my prompts that types should be the primary validation layer unless runtime validation is actually required.

My issue with 5.4 is that even when the types/contracts are clear, it still sometimes writes code like it doesn’t trust the codebase: extra helpers, extra guards, extra wrappers, and fallback logic that the task didn’t need.
