Deleting a tile left the cells painted with it in the tilemaps. They
drew nothing, blocked nothing and did not show in the delete dialog,
but still read as a tile for "Tile at" and stopped a fill.
- DeleteAssetCommand empties the cells of a deleted tile on every
layer of every tilemap in the same step. Undo puts the tile and its
cells back together.
- The delete dialog counts them, for example "3 cell(s) on 1
tilemap(s) are painted with it and become empty." (cellsPainted).
- presentTile treats a cell naming a missing tile as empty. "Tile at"
(World.tileAt) and floodFill use it, so cells already in existing
files read and fill as empty. There is no migration.
- The brush, the rectangle and the fill check the tile in hand. A
tile deleted after it was picked no longer paints new invisible
cells, the editor says "Choose a tile to paint with." instead.
- Unchanged on purpose: the picker still reports such a cell as
naming a tile that no longer exists, and erasing removes it.
Tests:
- ./check.sh: 195 files, 2823 tests, CHECK EXIT 0 (+6).
- GM_STEPS=39,40: ALL PASSED, 100 checks (4 new in 40t).
- Full e2e sum is now 1590 (1586 confirmed by CI on round 8, plus 4).
- Counter-checks, all fail as expected: 5 in unit tests (delete
without emptying, undo without cells, fill and "Tile at" without
presentTile, wrong map count) and 3 in the browser (dialog without
count, delete without emptying, brush without the check).

Recurring cleanup round over the code since round 6 (056a622), 105
commits. Behaviour is unchanged. Duplicated code in src went from 29
clones with 229 lines (0.32 %) to 14 clones with 109 lines (0.15 %),
measured with jscpd and the same settings as round 6.
- BehaviorSystem.ts shrinks from 941 to 589 lines. Collecting the
pulses (keys, timers, collisions, animations) moved to
behaviorPulses.ts. The NodeContext the nodes receive moved to
behaviorContext.ts. Imports from outside stay the same, TimeScaled
is still exported from BehaviorSystem.ts.
- PointKindButton and drawPointGrip replace the "Point:" button with
its menu and the point and handle drawing that the curve and the
vector art tab each had on their own.
- lerpVec, cubicAt and splitCubic in src/core/util/vec.ts replace four
copies of the cubic curve and two de Casteljau splits.
- mapNested in Properties.ts is the one walk over lists and structs
that liveObjects and objectRefs did separately. withFieldRenamed
and withoutField replace three copies of renaming a struct field
and two of removing one.
- jsonBody and staleRevision build the JSON body and turn a 409 into
StaleRevisionError for all stores. The auth store turns a 401 into
its error in one place.
- Smaller helpers: structAssetFrom for the two "Make struct type"
commands, shownObject in the inspector, selectedItem for the size
gizmo and the polygon corners, solidTiles in the tilemap collision,
requireVariablesAsset and requireBehaviorVariable.
- Left as is on purpose: the plain forwarding from the collision and
physics systems to Solids, the pointer wiring of the canvases and
the identical last lines of the two make commands.
- Removed unused code: tilemapTileIds and tilemapsUsing were never
called since #128 and #131. EditorState.runtimeProject became unused
with GameRun in #266. The assetId getter of the make commands was
read only by a test.
- 60 values used only in their own file lost their export. The shader
and particle node catalogues stay exported as in round 6.
- Five comments that told history now describe the current state. The
doc comment of BehaviorSystem sits on the class again.
- README lists the struct, clip area and curve assets and mentions the
game link from #266.
Findings:
- Deleting a tile that is painted on a tilemap leaves its cells in
place, and they draw nothing. The delete dialog does not mention the
tilemaps. That was probably the job of the unused tilemapsUsing.
Left as is, because fixing it changes behaviour.
- The solid filter for tile surfaces was untested. A bent filter
stayed green. A new test in tests/core/surface.test.ts now fails
against it.
Tests:
- ./check.sh: 195 files, 2815 tests, exit 0 (one test removed with
tilemapsUsing, one added for tile surfaces).
- Full e2e run: ALL PASSED, 1580 checks.
- Smokes jumprun, tetris, actor: 24, 19 and 21 checks, all passed.
The example project files were restored byte for byte afterwards.
- Counter-checks, 12, all fail as expected: 10 in unit tests (among
them mapNested, splitCubic, cubicAt, staleRevision, the stay pulse,
the late timer and the time scale), 2 in the browser (Point button
always enabled fails 47, selectedItem without a hit fails 29).

Part (a) of the animation rework: model, commands, saving, runtime and nodes.
- AnimationAsset holds a root (sprite, text, container or scene) and rows; a row keys one
property of the root or of an object inside it, keys sit on whole frames.
- The last key decides the length (its frame counts as a frame of its own). The playhead runs
between frames, so numbers and colors blend every tick even at 10 fps; everything else holds.
- Playback gains `once-reset`, which puts back what was there before the start. A row can be
relative, adding to where its target stood.
- Play / Pause / Stop animation act on an object; each instance plays on its own, the later
start wins on a shared property, and a behavior writing the same property still writes last.
- A sprite no longer wears an animation through `texture`. "Create animation from texture"
builds a sprite plus a texture row keyed frame by frame instead.
- The Animation tab shows a placeholder until the timeline editor (part b) lands.

A shader is an asset carrying a node graph (Texture color, Output, Property,
Color, Add/Subtract/Multiply/Divide, Mix, Luminance) that compiles to the GLSL
fragment of a Pixi filter. The Shader tab reuses the Behavior canvas; a sprite
wears a shader through its Shader picker, and the rows below it are the
graph's Property nodes. Property schema, resolution and deviation take the
project because a sprite's rows now live in another asset. The built-in
registry of the prototype is gone; "Adjust colors" ships as a graph in the
fixture and the three example games.

A kind like colour or texture used to be spelled out in five parallel
lists, its port type, its empty value, its glyph, its label and its list
tag - 22 literal places for texture alone. core/properties/kinds.ts now
holds one row per kind and the rest is derived from it, so adding a kind
is one row. The five literal nodes collapse into literals.ts, the six
kind menus into one helper.
Number, Text, Boolean is now the one order everywhere; the variable and
port menus used to list Boolean before Text.

An animation asset is a list of pictures (whole textures or frames) with
frames per second and Loop/Once/Ping-pong playback. A sprite wears it
through its texture property, so the picker, instance overrides and the
Properties node work unchanged; there is no dedicated play node.
A different animation starts from its first frame, the same one set again
runs on, so a graph may choose Run or Idle every frame. The clock lives on
the entity, not in props, which the world writes back as overrides. The
AnimationSystem ticks before behaviors, and On animation finished fires
once when a Once animation reaches its end.
The Animation tab plays a preview above a frame strip: reorder by dragging,
Delete, duplicate, + Frames, pause/resume, and wheel zoom about the pointer
with pan and Fit. Scene and Container tabs show the first frame; edit mode
has no clock. Right-clicking a texture creates an animation from its frames.
Button now measures its label with the bold font it draws in, which cut
the Animation tab and red dialog buttons short.

findPropertyUsages walks override sites, so Project.ts imported instance.ts
while instance.ts imported Project.ts – the repo's only value-level import
cycle. The queries now sit in usages.ts and Project.ts is a base type module
again. requireScene has had no caller since holderId replaced sceneId.
