I'm using a AIs like Arena and Claude to port the classic MS-DOS game Jazz Jackrabbit to Sega Genesis.

Welcome! It's impressive that you've got your code running on a Genesis and the color reduction doesn't look too bad, but there are some pretty bizarre things in your changelog, for example:

We completely rebuilt how Jazz's animations are handled by reading the actual 38-state animation machine from the open-source PC engine.

Jazz 1 is not open-source! Are you thinking of OpenJazz? That's another fan recreation, like yours, it can't guarantee to be accurate in this regard.

We discovered that the original game actually drew entirely separate graphics for left-facing and right-facing enemies rather than just "flipping" them in the code.

This seems like a really basic thing to discover when you can see it for any object by looking at them in J1E or even JJ1MOD, or looking up the file formats on ModdingWiki. I really think you're going to have an easier time of this if you reference all the existing research and tools for Jazz 1, rather than start from scratch.
