The game as of artifact version 24, ready for local development with coding agents. - Source split from three large files into 52 small ones under src/sim, src/render and src/ui, joined in the order in src/manifest.json by build.py. The joined code is unchanged apart from comments; every headless suite gives the same output, and screenshots in both looks are pixel-identical to before. - Light tidying with no change in behaviour: one movement scan loop, shared hazard-stripe and belt shader helpers, unused code removed, a shared check helper for the test suites. - World files can be exported as an ordinary download outside claude.ai. - Tests: broken old scripts removed, experiments moved to tools/, test/run_all.py added. Tools: shot.py (repeatable screenshots), where.py, map.py. - Docs: AGENTS.md, CLAUDE.md, NOTES.md (the owner's to-do inbox), docs/PROJECT_MAP.md, DESIGN.md, TESTING.md, systems notes, the owner's requests and an agent log.
