@cwebber @glyph The other thing that struck me is that LLMs are pretty good at this kind of static code review.
I tried asking Claude and Meta.ai about the modified Navigator.py according to Yee's description. Claude found the first two errors quickly, but never found the third:

Meta.ai found two also:

Anyways, neat exercise.
