# Baryon Engine > A world engine for real places on Earth, built so that everything has a cause. Generated from main at 155144d46d43f1a775a1532490344d6c42f4de8e; every value comes from a receipt there. World status: paused. The world is paused until bodies move by cause. ## Docs - [Laws](docs/laws/index.md): one page per declared law (64), with its readiness and its register rows - [Exams](docs/exams.md): recipes you can run, with the result at this commit - [Receipts](receipts.json): every row on the site, machine-readable ## Not yet - The SDK: it waits for step 2 (the command envelope) and ON40; until then the shapes are about to change. - Command and Observation schemas: they will be dumped from the compiled Codable types by a GenesisBench command.
