A graph had no way to know how big a picture is. An icon sprite with a
fixed size therefore stretched every icon of another size, an 8x8
pixel-art icon in a 16x16 slot was drawn twice as big.
- New data node Texture size. It takes a texture, a frame or a pixel
art and hands out width and height in pixels, 0 x 0 for none.
Wired into a sprite's width and height, the picture shows pixel for
pixel.
- GraphLookup gets textureSize. The project answers it with the same
pictureSize rule a sprite uses to size itself.
Tests:
- ./check.sh: 2749 tests, CHECK EXIT 0.
- 2 catalog cases (a picture, no picture) and one test against a real
project: pixel-art sheet, single frame, missing texture.
- No e2e check and no counter-check for this node.

Name, opacity and Z each sat in a separate field below or beside
the list. You had to select a row first and then look elsewhere to
change it. Duplicating was a separate button or not possible at all.
Now the row itself carries everything.
- SortableList gets three optional callbacks. onDuplicate shows a
copy button between the eye and the delete button. onRename opens
a text field on double click, Enter or a click outside commits,
Esc cancels, an empty name is ignored. value puts a NumberField
into the row.
- Dragging on the number changes the value and never moves the row.
A whole drag is one undo step, the canvas follows live.
- Copy and delete only show on the hovered and the selected row.
Their space stays reserved, so nothing jumps on hover.
- Pixel layers: copy right above with the same pixels on all
frames, rename, opacity in percent. The Name and Opacity fields
below the list are gone.
- Pixel frames: copy right after, replaces the Duplicate button.
- Tilemap layers: copy with cells, Z and visibility, rename, Z in
the row. The Name and Z fields in the panel are gone.
- Vector shapes: copy at the same place and select it, rename.
- New in core: DuplicateVectorShapeCommand,
DuplicateTilemapLayerCommand, withLayerDuplicated and copyName
("X copy", "X copy 2"). copyName lives in src/core/util/names.ts
because the model never imports from commands/.
Findings:
- Double clicking a shape that is not selected yet only selects it.
The first click moves the list up, so the second click misses the
name. Module 47 selects the row first.
Tests:
- ./check.sh: 138 files, 2055 tests, CHECK EXIT 0 (before 2052).
- GM_STEPS=47,48 (fresh, twice): ALL PASSED, 91 checks (before 86).
- GM_STEPS=39,40,47,48: module 40 green, 47 died on the rename
check, which was a test fault and is fixed.
- Counter probes: a constant copyName fails the shape and pixel
layer tests. A dead copy hit fails the copy check in 47.
- Check total 1272 in README and wiki, computed (1266 + 6).

Textures are uploaded files named by their content, so they cannot
be edited in place. Pixel art is therefore its own asset type, like
vector art. Its pixels live in the project and the tab rasters them
into a texture that sprites, tiles and animations can use.
- New asset types Pixel art and Palette. The first pixel art of a
project gets a palette with the 16 PICO-8 colours in the same undo
step. Every pixel is a palette index, 0 is transparent.
- Each layer on each frame is its own file data/pixels/<sha256>.px.
The project only holds the names, so undo swaps names. The browser
computes the hash and uploads new cels before the project is saved.
- New route POST ?r=pixels in api/lib/PixelStore.php. It answers 201
and 422 for broken data. data/pixels/ is git-ignored.
- Tools: pencil, eraser, fill (contiguous or all pixels of a colour),
eyedropper, line, rectangle and ellipse (outline or filled), brush
size 1 to 8.
- Layers can be added, deleted, renamed, reordered, hidden, faded and
merged down. Frames can be added, duplicated, deleted and reordered,
with onion skin and a small playing preview.
- Zoom 1x to 32x in whole steps, grid from 8x, a 3x3 tile preview and
Resize... with a 3x3 anchor.
- All frames sit side by side in one image. Each frame is a region
like a cut texture frame, so texture rows offer "Asset / Frame 2"
and the context menu has Create animation from frames.
Decisions:
- Merging down drops the opacity of the upper layer. Indexed colours
know no blends.
- Only the last palette colour can be removed. Otherwise the indices
of every image using the palette would shift.
- Undo stores the whole layer per stroke instead of pixel diffs.
- Alt+click picks a colour. It is a mouse gesture, not a shortcut.
Follow-up issues: #197 import from texture, #198 selection and
flipping, #199 PNG export, #200 more tools.
Tests:
- ./check.sh: 136 files, 2049 tests (before 135 / 2011). 34 new in
tests/core/pixel-art.test.ts, 4 from the icon tables.
- e2e module 48 fresh: ALL PASSED, 29 checks, console empty.
- Counter-probes bite: five on the unit tests, upload order (2 tests
fail) and cels not uploaded in the browser (1 check fails).
- Check total 1259 in README is computed (1232 measured in CI + 27).
