I setup the initial project to get claude started in a structure I like and there are some shared libs that I had written before AI lol

The constraints were built up over time as we did the project; claude.md also got pruned several times to move things around so it references other files as claude finds it needs that information

yea, I am looking into how I can maybe fine tune a model for a more data-oriented world view

Benchmarked against bitECS/miniplex.- Process manager inspired by Game Code Complete's but data-oriented so processes are pure data, systems contain the logic.- Multi-field gravity with 5 types (point, parallel, segment, cylinder, convex hull)...
