- Areas within 150 grains of the bot start at once; the others 12 a tick, nearest first, and any
the bot flies toward start straight away. A Huge world is fully started after 17 s.
- Huge world, first 600 ticks: average 15.2 -> 5.5 ms/tick, worst 79.7 -> 16.2.
- New test/t_load.js.

- One helper each for wall and mold refunds, tube edges and lanes, pipe text, piece dimensions,
font lookup, reach circles and surface averaging.
- previews, smooth, notebook, materials, worldgen and selection split into topic files
(preview-drill, preview-selection, smooth-shaders, notebook-market, notebook-blueprints,
material-tables, worldgen-helpers, selection-pickers, selection-panels).
- Every suite's output identical apart from timings; seeds make the same worlds.

- The roof is rescanned only in area columns that changed since the last scan: a quiet Huge
world goes from 4.60 to 1.88 ms per scan (every 20 ticks).
- The heat pass skips react() for solids and powders below their first reaction threshold:
Huge world digging 2.54 -> 2.34 ms/tick, quiet 1.39 -> 1.18.
- Every suite's output is identical apart from timing lines; seeds make the same worlds.
- test/t_sim_optimizations.js checks the dirty roof against a full scan and the heat loop
against the reference loop byte for byte.

- SORTP 0.003 -> 0.06: ore sinks through 8 rows of ash in about 7 s near the bot.
- wakeBotPowder(): every 8 ticks, areas with loose grains within 100 grains of the bot get a
sorting chance; far away, resting piles still sleep.
- Sinking through burning fuel stays at 0.003, so buried burning piles still char and furnace
beds behave as tuned. World generation settles at the old rate: seeds are unchanged.

- New test/t_physics.js: heaps, sorting, sinking, world edges; molten copper levelling, setting,
quenching, slag over copper, cavity filling; smoke, steam, fire, sealed pockets, the top row.
- Gas in a sealed pocket kept its area asleep and never faded or condensed: gas() keeps its area
awake while it lasts.
- A rain drop or blown grain landing on steam deleted the steam's water: it goes to the clouds.
Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
- 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 hint and Clear button were inside the scrolling bag list, so a long
Ctrl list scrolled them away. They now sit in a footer under the list, and
Clear is a full-width, highlighted "Clear selection" button.

Blowing out the last of a selected material removes it from the selection,
so an emptied selection picks up what you click again. Ctrl + wheel never
zooms the page and scrolls the bag list under the mouse. A bag click while
Ctrl is held adds to the selection even if the click lacks the Ctrl flag.

With anything selected a drag takes only the selection; with nothing
selected it takes what you click. Right click blows the selected materials
in the bag. Holding Ctrl lists every material found so far under "Not in
bag". Selections stay when materials run out; Clear button, clicking the
only selected row, or gamepad B clears.

A drag takes only the material it starts on (Shift: everything). The blow
selection is the hand: click or Q/E for one material, Ctrl+click for a mix.
Empty materials leave the hand, an empty hand blows nothing, and a pickup
fills an empty hand. Removes the pick-up marks and the F vacuum menu.

Also: board rule to write tasks from chat in our own words, task
descriptions rewritten that way, and a note on lost web-board descriptions.

Pick-up takes everything unless something is marked; F with the Vacuum
(when nothing in reach can be used) or the card chips open a menu with
pick-up and blow toggles per material. The bag rows lose their buttons.

Each note is a task in tasks/ with the owner's words under ## Context; the
board rules are in .kandown/kandown_work.md and docs/kandown.md explains how
kandown works here.

Ctrl (replace) + W (fly) hits the browser's close-tab shortcut, which a page
cannot block. A beforeunload prompt now catches it. Autosave on hiding the
tab no longer depends on the audio context.

The short description row became a status row for the selected piece
(variant, Replace, ghosts, messages). Gamepad shows the selected tile's popup.

carryColumn stops at the first blocked grain on a belt, so a heap whose front
is backed up (a screw tube taking less than the belt brings, or a wall) no
longer shears. New t_conveyors checks and a belt-heap screenshot scene.

Bars no longer get thrown up into the furnace, and F is no longer needed to
collect them. Blocked bars wait in the trough; the short stub stays for the
next firing; F is optional upkeep (clean, chip slag, rake).

The browser tests and screenshot tools now work with plain python3 on a machine whose
system Python refuses pip installs: tools/use_venv.py re-runs them with the repo's .venv.

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.
