- Liquids step up to 8 cells a tick toward a drop (fewer the thicker they are), and a top-layer
grain looks 4 times as far for one, so pools empty and thin film drains. A 100-wide pool
empties in about 50 s; the old code left 24-650 grains stranded on wide ledges.
- Only a top-layer grain stepping sideways wakes the row ahead, so settled lakes still sleep.
- World generation settles at the old speed: seeds make the same worlds as before.
- Cooled steam under a roof no longer stays steam for ever (its heat area slept).
- Raining clouds keep drifting at half pace and rain over a band either side, so a waterfall into
a hot shaft no longer rains straight back on its own lake.
- New test/t_water.js; t_weather rain-location checks; t_conveyors counts steam in flight;
t_molds seeds the random burning-bed check.

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.
