The magic grip is gone: cleats every 8 face cells, 6 grains tall, carry
pockets uphill (about 71 grains/s against 90 flat) and overflow rolls
back. Sloped filters always run downhill; grains travel by gravity and
a shake, and sorting stays exact. Drawing needs another pass.

Player text says Screw conveyor; code uses screw (BP_SCREW, piece id
screw, screwIntake...). No compatibility code for old saves or
blueprints. Suite outputs match before and after apart from names.

- Tubes run in eight directions: a drag at about 45° lays a diagonal run, R cycles all eight.
- Diagonal runs carry grains at the straight rate (120 grains/s), join straight tubes and belts,
keep grains in at the corners, pass water, and carry bars level.
- New part ids 11-14 (saved ids are never renumbered); tube checks use an IS_TUBE table.
- New test/t_diag_tubes.js (85 checks).

- New Sloped wall piece: a half-block triangle in any wall material, at half a wall's cost.
Dragging walls or slopes at about 45° lays a diagonal line; the drag picks the slope's
orientation and T flips or turns it.
- Each slope fills one cell past its corner, so a diagonal run is sealed against grains and water.
- New test/t_slopes.js: a slope funnel passes 400/400 sand (square steps 379/400).

- 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.

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.

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.

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

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 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.
