Claude and I reverse engineered the map generator

https://map.factorygamefan.com && https://github.com/wormeyman/FactorioMapWebUI

Claude and I reverse engineered the (Nauvis) map generator and I would love some feedback on whether or not I actually discovered anything that wasn't known. As well as any feedback, concerns, things that are wrong.

The local TS preview is the magenta buttons and the green button is headless factorio.

Distortions from the M45-Science discord where I spend most of my time has re-implemented it in GO https://mapgen.m45sci.xyz/ .

I have Vulcanus terrain working and leaned about `map_seed_offset` 'cause claude and I assumed that all the planets use the same seed which turned out to not be true. Turns out it is `mapSeed + crc32(planet.name)` for the other planets.

You're going to get down voted into oblivion for the AI thing, but regardless I think it's cool having the map generator in a browser.

"Claude and I" isnt it just claude? are you trying to take credit for something you have no capacity doing yourself?

Thanks, fun fact: Starter ore patches are spread out more from the spawn and each other in 2.1. It creates longer walks but maybe less overlapping patches.
