netherite

From-scratch C/CUDA Minecraft 1.11.2 (bit-verified vs the real Java game) + batched CUDA RL.

One env's semantic camera, zooming out to 7,200 live worlds stepping in lockstep on one GPU (recorded from a real batch).

Platforms

	Support
Linux x86_64	Full stack (build, CUDA train, Java oracle). Canonical: anvil.
macOS	Viewer / SSH only (Moonlight, mcwindow). No native game or CUDA train.
Windows	Not supported as a build host.

No Mojang content is shipped. You need a legal Minecraft ownership and JDK 8.

Using an LLM on this repo

Open AGENTS.md (Claude also loads CLAUDE.md). Or paste:

Read AGENTS.md in this repo and follow it. Task: <what you want done>

Clean Linux box (one command)

bash scripts/setup_and_verify.sh          # bootstrap + build + --quick sweep
bash scripts/setup_and_verify.sh --demo   # + physics/pixel tape replay + SBS MP4
# -> demos/pixel_match_sbs.mp4  (oracle | magma side-by-side)

Prism is optional. Bootstrap uses ForgeGradle; details in docs/BOOTSTRAP.md. Pixel demo uses the shipped canonical tape under verify/demo/.
