Sounds like most of this is simply taking shortcuts instead of properly parsing[0].

I'd rather view it as a failure to distinguish between data and logic. The status-quo is several steps short of where it needs to be before we can productively start talking about types and completeness.

Unfortunately that, er, opportunistic shortcut is an essential behavior of modern LLMs, and everybody keeps building around it hoping the root problem will be fixed by some silver-bullet further down the line.
