I’m surprised you bothered writing software instead of writing some G code by hand for testing

when you have claude everything looks like a software problem :)

Because that's not accessible.
IMO the reason other efforts to achieve similar Z reinforcement have gone nowhere is because it was one guy fiddling with G-Code. All the big innovations in 3DP have been community projects. Now anyone can download my binaries and try it.
I'm personally very convinced this will work. That's why I did it. We just need to figure out the right settings. Maybe use a different material for injection or coat the nozzle in something.
We'll see. There's a long history of crazy ideas and cold receptions. We even have famous examples from this site https://news.ycombinator.com/item?id=9224
Either I'll end up wrong, and this will fade into obscurity. Or it will turn out I was right and a lot of people will read this comment someday.
The top of cells always melt as I'm using the same material for injection and the rest of the print. Someone with a dual nozzle printer could try something like PLA injection in a polycarbonate part. I added support but don't have a printer capable of that.
It's also possible that different print settings would work. I'm releasing the features to the community as I've run out of patience with doing a hundred hours of test prints.
We need to crowd test the best settings and nozzles, materials, etc to make this work well
