adminandClaude Opus 5.5 f02adabcf9 Show the type an arithmetic shader node really puts out (#219)
The result of Add, Multiply, Mix and the other arithmetic nodes of
a shader graph was drawn as any, whatever went in. The compiler
already lifts a colour on any side to a colour result, so the pin
said less than the code knew. A colour result could also be wired
into a number input, and the shader then failed to compile.

- liftedType in core/shader/nodes.ts is the one rule. The compiler
  reads it when it lifts two operands, and the editor reads it
  through liftedPortType for the ports it draws.
- A SharedPortGroup may bring its own rule as agree. Without one
  it is agreedType, as before. The thirteen arithmetic nodes share
  their type by liftedPortType.
- Only the any inputs decide. An input nothing feeds counts as the
  number typed into it. t, edge, exponent, min and max have no say.
- The type travels through a chain of such nodes without code of
  its own, because #210 hands a shared type on.
- In a ring the result stays any, unless a colour has settled it.
- A number may feed a colour input. Without that a number result
  no longer fitted Output.color, although the compiler spreads it
  over three channels. The rule sits in portsCompatible, but only
  the shader graph has colour ports.
- A colour result no longer fits a number input. An edge laid
  before the colour came in stays and is drawn in the danger
  colour, and the node at its end names the problem.
- The nine shaders in the stored projects (108 edges) all stay
  valid under the new rule.

Tests:
- Gate on melektaus-atx: 212 files, 3260 tests (3240 + 20), exit 0.
  The gate right before this commit ran on the tree of this and
  the next commit together, with the same numbers.
- e2e 28 on melektaus-atx: 81 checks, all pass.
- e2e 1-31: 1059 pass, 1 fail in module 18 (the editor clock read
  1.97 s after a stop). A rerun of 1-18 passed with 602 checks and
  0.18 s. 1-31 was not run in full again.
- No full run and no smokes. The sum of 1676 (1673 + 3) is reckoned.
- Twenty unit tests in shader-port-types.test.ts, one of them runs
  all thirteen nodes through every mix of number and colour and
  compares what is drawn with the code made.
- Two tests in shaders.test.ts now lay the edge first and bring the
  colour in after, the only order that still wires such a graph.
- Three e2e checks in module 28 with the real mouse: a colour into
  Multiply, the red edge with its message, and the colour result
  refused at alpha and taken at color.
- Fifteen unit counter-probes and two browser counter-probes all
  fail their tests.
- Not checked in the browser: the one-input nodes, Mix and the
  ring, and a number wired straight into a colour input. Nothing
  was looked at after the build.

adminandClaude Opus 5.5 9ca220a285 Hand a shared port type on through a chain of nodes (#210)
game-maker / gate (push) Successful in 2m51s
game-maker / suite (push) Successful in 14m44s
Since #207 the output of First not empty or Select takes the type
its inputs agree on. A second node of that kind behind the first
stayed any, because the first one answered with the any it was
registered with. That was the guard against a circle of such nodes
asking each other forever. The issue asks for the type to travel
through the chain. Answered there: measure with 50 nodes and build
no cache, and the painted input pins follow along.

- shapedDef in core/graph/nested.ts takes a Trail in place of the
  flag inherit. Its set open holds the nodes still being asked. A
  node reached a second time reports the any it was registered
  with, which ends a circle.
- The map done of the Trail keeps each answer of one question. A
  node feeding both inputs of the next is asked once, so the work
  does not double with every link of a chain.
- ownShape is the part of shapedDef that builds the ports before a
  shared group has its say. It is split off, nothing in it changed.
- Inputs stay any and only outputs inherit, as in #207. An edge
  that turns invalid further down is left in place and drawn in the
  danger colour.
- paintedInputs uses one Trail for all pins of a node, so the pins
  show the type handed on through the chain.
- Nothing is cached between two changes. A chain of 50 resolved in
  about 10 ms where it took 2 ms before, measured earlier in this
  round and not again for this commit.

Tests:
- Gate on melektaus-atx: 211 files, 3240 tests (3227 + 13), exit 0
- e2e 1-6 on melektaus-atx: 298 checks, all pass
- e2e 4,6,18,19,20,23,24,26,28,31,36,43,53: 558 checks, all pass
- No full run and no smokes. The sum of 1673 (1671 + 2) is reckoned,
  1671 is what CI counted for c88f57c.
- Fourteen unit tests in shared-port-type.test.ts: a chain of two
  and of three, mixed kinds, a mixed and an open input, undo at the
  front, a circle of two, a node feeding itself, behind a circle, an
  invalid edge further down, the chain of 40 asked once per node,
  the chain of 50, and two for the pins. The test saying the type
  does not pass through a second node is gone, hence 13 more.
- Two e2e checks in module 06: the second node takes number, and a
  text at the front opens the whole chain again.
- Four unit counter-probes and one browser counter-probe all fail
  their tests. With the old behaviour only the chain check fails.
- Not checked in the browser: the circle and the chain of three,
  which have unit tests only. Nothing was looked at after the build.

adminandClaude Opus 5.5 c88f57cf0a Let a project choose how its game link is zoomed (#279)
game-maker / gate (push) Successful in 2m52s
game-maker / suite (push) Successful in 14m31s
The page of a released game always drew the camera at Auto, the
largest whole step that fits. A camera of 300x180 in a window of
1280x800 stands at step 4 and leaves a border left and right. The
issue asks for Fit next to it. Answered there: a setting of its own
rather than the scale of the Game tab, and no switch for the player.

- The project has a field gameLinkZoom, 'auto' or 'fit'. A document
  without it reads as 'auto', so nothing changes for a project that
  is there already. No format bump.
- Project settings has a row "Link zoom" with a menu of Auto and
  Fit. It is an undo step of its own, SetGameLinkZoomCommand.
- GameScreen hands the field to cameraView where it passed a fixed
  'auto'.
- gameScale, the scale of the Game tab, is not touched and does not
  reach the link.
- The released copy is frozen, so the change reaches the link only
  with "Update release".

Decided here:

- The row is called "Link zoom", not "Game link zoom" as proposed.
  The longer label is wider than the label column of the dialog and
  pushed its button 12 px out of line with the others.
- The undo step keeps the name "Game link zoom", which is what the
  tooltip of the undo button shows.
- A note under the row says "The released game at the largest whole
  step that fits, or filling the window."

Tests:
- Gate on melektaus-atx: 211 files, 3227 tests (3219 + 8), exit 0
- e2e 60 on melektaus-atx: 19 checks, all pass
- e2e 35,46,59,60: 74 checks, all pass
- No full run and no smokes. The sum of 1671 (1668 + 3) is reckoned,
  1668 is what CI counted for 9e869df.
- Eight unit tests: the default, saving and loading, values that
  are not a choice, undo, gameScale left alone, the factor of Fit
  for a window larger and smaller than the camera, and the rule
  behind Apply.
- Three e2e checks in block 60i of module 60, with the real mouse:
  Auto to Fit in the dialog, update the release, open the link
  without a session and measure scale, frame and pixels. Fit reads
  4.267 where Auto reads 4.
- Nine unit counter-probes and three browser counter-probes all fail
  their tests.
- Not checked in the browser: Fit in a window smaller than the
  camera, which has a unit test, and Fit under a display scale above
  100 %. Nothing was looked at after the build.

adminandClaude Opus 5.5 345289982b Scale, turn and mirror the shapes of a vector drawing (#291)
game-maker / gate (push) Successful in 2m57s
game-maker / suite (push) Successful in 14m25s
A shape could only be moved and reshaped point by point. Whoever
wanted it larger or turned pulled every point alone, and for several
shapes or a group there was no way at all. The answers in the issue
settle the rest: the change is baked into the points, nothing of it
is remembered, and the line width stays.

- With Select the selection stands in a frame of eight squares and a
  knob, drawn like the one of the scene view. It holds one shape,
  several shapes or a group, the same selection that is dragged as
  one.
- A corner square scales from the opposite corner, a square on an
  edge in its own direction. Shift keeps the proportions, Alt scales
  about the middle.
- The knob turns round the middle of the frame, with Shift in steps
  of 15 degrees. After the pull the frame stands upright again.
- The inspector has a band TRANSFORM with X, Y, Width, Height and
  Rotate by, and the buttons Flip horizontal and Flip vertical.
- Points, handles, gradients and texture tiles are taken through the
  same matrix. The rule is a pure function in vectorTransform.ts,
  transformShapesCommand makes one undo step of any number of
  shapes.
- A press goes to a point or a handle first, then to the frame, then
  to a line. shapeFrame.ts holds where the handles are and what a
  pull of each means.

Decided here:

- The frame stands 15 pixels off the shapes. The points of a shape
  lie on its bounds, so a square on the bounds would cover them.
- The knob only turns. In the scene view it scales as well.
- A side cannot be pulled through the opposite one, the frame keeps
  at least 1 pixel.
- Coordinates are rounded to a thousandth of a pixel, so a quarter
  turn is exact.
- A texture tile stays upright under a turn and grows to the bounds
  of the turned tile. The bands of a gradient stay square to its
  axis under an uneven scale.
- The switch Scale stroke of the proposal is not built.

Found on the way:

- The inspector of a shape is now taller than the window. Two checks
  of module 47 no longer found their row or button on the screen and
  use the new hook inspectorButton, which scrolls there first.
- Not solved: with a shape at the top edge of the view the knob lies
  outside the tab. The wiki names it under the limits.

Taken over from #217: the e2e check for two selected shapes without
a group, and unit tests for the snap of the common offset and for
the gradients of the shapes dragged along.

Tests:
- Gate on melektaus-atx: 209 files, 3176 tests (3121 + 55), exit 0
- e2e 47,48 on melektaus-atx: 112 checks, all pass
- No full run and no smokes. The sum of 1664 (1660 + 4) is reckoned,
  1660 is what CI counted for 6d79cf5.
- 55 unit tests: 25 in tests/core/vector-transform.test.ts and 30 in
  tests/editor/shape-frame.test.ts
- Four e2e checks in block 47k of module 47: pull a corner, turn
  with Shift, type width and rotation, drag two shapes without a
  group
- 47 unit counter-probes and four browser counter-probes all fail
  their tests. Four of the unit ones did not at first: two showed
  dead code, which is gone, two got tests.
- Not checked in the browser: the edge squares, Alt, the cursors,
  the flip buttons and the rows X, Y and Height

adminandClaude Opus 5.5 275e50af01 Let a tile report a touch instead of blocking it (#160)
A tile could be solid, one-way and scaled, but not report without
blocking. Water, lava, spikes or a goal zone needed a trigger object
of their own laid over the map. Now a tile has a switch Trigger, and
the collision events name the tile and the cell they met.

- A tile has the switch "Trigger (reports, never blocks)" under
  Solid. Its cells hold nothing up: no Move, no falling body, no
  ray. They raise On collision enter, stay and exit with the tilemap
  as other.
- The three events have the outputs tile, cell x and cell y. Without
  a tile, tile is empty and the cell is -1, -1.
- The three events have the input per cell. Off, the default, gives
  one event per area: cells of the same tile that touch side by
  side. On gives one event per cell.
- The scene view outlines trigger cells in yellow like a trigger
  collider, merged to rectangles but never with solid cells.
- Is touching with the map counts trigger tiles, and Set tile works
  while the game runs.
- Both systems find the touches with the same overlap check in
  runtime/systems/tileTriggers.ts, not through the physics engine.

Decided here:

- Trigger wins over Solid. A tile with both does not block, as with
  a collider.
- Water beside lava is two areas, and so are two ponds that touch
  only at a corner.
- An area names the cell nearest to the centre of the collider, and
  on exit the cell it named last.
- The solid cells of a map still do not name their tile.
- Normal, impulse and point are 0, as with a trigger collider.
- Collision scale and outlines shape a trigger cell like a solid
  one. One-way, friction and bounciness have no effect.

Tests:
- Gate on stein2: 205 files, 3104 tests (3067 + 37), exit 0
- e2e 39,40: 106 checks. e2e 1-8,39-43: 490 checks. Both on
  melektaus-atx. No full run, the sum of 1648 (1645 + 3) is
  reckoned and CI measures it.
- 37 unit tests in tests/core/tile-triggers.test.ts, nearly all
  against both systems
- Three e2e checks with a real mouse in block 40l-iv
- 24 unit counter-probes fail tests. Two did not at first, tests
  were added for them.
- Two browser counter-probes fail their checks
- Two screenshots looked at (yellow outline, the node with per cell)

adminandClaude Opus 5.5 2ff3a78607 Put the shapes of a vector drawing on layers and in groups (#190)
game-maker / gate (push) Successful in 2m41s
game-maker / suite (push) Failing after 7h24m17s
A vector drawing was one flat list of shapes. With many shapes the
list got hard to read, and several shapes could not be kept or moved
together. Now the shapes stand on layers, as in pixel art, and can be
put into groups that nest.

- A drawing has layers, each with a name and an eye. A hidden layer
  is neither in the tab nor in the picture a sprite wears, and its
  shapes cannot be pressed. One layer is the one worked on: the pen
  and Add shape draw onto it, and SHAPES lists what is on it.
- The inspector has a list LAYERS over the shapes. Its plus adds a
  layer, the cross on a row removes it with all on it, the last one
  stays. A double-click renames, a drag sorts.
- Group (Ctrl+G) puts the selected shapes into a group, Ungroup
  (Ctrl+Shift+G) takes it away. A group stands over its rows in the
  list, the rows one step in, and a row is dragged into a group or
  out of it.
- In the tab a press on a shape takes its outermost group, and a drag
  moves the group as one undo step.
- The model has layers with a tree of shapes and groups instead of a
  flat shapes array. The rules are pure functions in
  core/model/vectorTree.ts. A drawing saved before opens with all its
  shapes on one layer.
- SortableList takes rows with a depth and drops into a tree. The
  flat lists of tilemap and pixel art run as before.

Decided here:

- A group has no transformation of its own and cannot be hidden or
  locked. Rotating and scaling is the follow-up #291.
- A group is never empty: the one that loses its last shape goes
  with it.
- Several selected shapes are dragged together, grouped or not, and
  a click on a shape of the selection keeps the selection. This is
  what #217 asked for.
- Shift+click selects like Ctrl+click. With Select, Shift pans only
  beside the shapes, as in the scene view. The middle button pans
  anywhere, and with the pen and Paint Shift pans as before.
- A row of the list picks one shape of a group alone.
- Shapes change their layer through a row Layer in the inspector,
  which is there from two layers on. Rows are not dragged between
  layers.
- A group cannot span two layers, the button is off then.
- The pen does not draw onto a hidden layer, the hint says so.
- Groups are always shown unfolded.
- The four order buttons work inside the own group or layer.

Tests:
- Gate: 204 files, 3067 tests (3008 + 59), exit 0
- e2e 47,48: 108 checks. e2e 39,40,47,48 before the Shift change:
  209 checks. No full run, the sum of 1645 (1639 + 6) is reckoned
  and CI measures it.
- 59 unit tests: 36 in tests/core/vector-tree.test.ts, 23 in
  tests/editor/vector-layers.test.ts
- Six e2e checks with a real mouse in block 47j
- 47 unit counter-probes for layers and groups and three for the
  Shift click all fail tests, run on stein2
- Three browser counter-probes fail their checks
- Two screenshots looked at (group in the list, hidden layer)
- Only unit tested: the row Layer, sorting and removing layers,
  copying a group, the Shift pan beside the shapes

adminandClaude Opus 5.5 1aa824ecb4 Keep objects through a Load scene with a switch (#165)
game-maker / gate (push) Successful in 2m37s
game-maker / suite (push) Successful in 13m2s
A Load scene destroyed every object of the old scene. A player, a HUD
or a music object had to be built again in each scene, with its state
pushed through shared variables. A top-level object with the new switch
Keep on scene load now travels into the next scene as the same entity,
with everything below it.

- The switch is a common property right under Enabled, off by default,
  on the asset and on a placed object. The inspector shows the row on
  top-level objects of a scene only, as answered in the issue.
- runtime/keptObjects.ts holds the rules as pure functions.
  keptEntities picks what travels, objectsToBring copies the stored
  objects as the run parents them, and bringObjects puts them into the
  next scene.
- World.instantiate takes a handed entity as it is instead of making
  one. The next syncToModel then writes the run's values into the
  scene.
- BehaviorSystem.release takes the running instances out before the
  old world is destroyed, and the next system adopts them. They hear
  no On destroy and no second On start, and their sounds play on.
- PhysicsSystem.resume gives a dynamic body the velocity and spin it
  had.
- Duplicates: the object brought along wins. The next scene does not
  build its own object with the same id, which is the way back into
  the scene the object came from.
- Decided here: the next scene does not build a top-level object of
  the same asset that is kept itself either. The issue only names the
  id. With the id alone a level that places its own player would hold
  two after a swap.
- Decided here: kept objects land behind the scene's own, the switch
  is no animation row, and collisions are found anew.

A finding, fixed along with it: Load scene did not build a scene as it
is stored, but as the run had left it. A moved object stayed moved and
a destroyed one stayed gone. The way back into a scene needs a clean
build.

- GameRun copies a scene's objects and groups before it first builds
  it and puts them back before it builds it again.
- GameRun.end puts every such scene back. The player calls it on stop,
  so spawned objects no longer stay for "Click to play again".
- The consequence: an edit made in a scene during Play is gone the
  next time that scene is loaded.

Tests:
- Gate: 199 files, 2944 tests (2929 + 15), exit 0
- e2e, full run: 1625 checks passed (1619 + 6), exit 0
- Smokes: 24 / 19 / 21, exit 0

- Six e2e checks in module 35: the switch is set with a real mouse,
  the child has no row, the object is in the new scene, its counter
  still reads 1, its sound plays on, and the stored scenes are
  unchanged after Stop
- Eleven tests with fixed row lists only count the new schema row
- 16 unit counter-probes all fail tests, run on stein2. One did not
  fail at first (same id not left out), it has its own test now.
- The browser counter-probe fails 4 of the 6 new checks
- Not looked at in the browser: the switch as a port of the Properties
  node, and a released game with a kept object

adminandClaude Opus 5.5 3e8c88c66d Add a node that names the collision layer of an object (#211)
game-maker / gate (push) Successful in 2m36s
game-maker / suite (push) Successful in 13m16s
The issue asked for three nodes: Set layer, Set collides with and Layer
of. A probe showed that the finding behind the first two is outdated.
The Properties node of type Collider already writes both settings while
the game runs, and both collision systems see the change at once. As
agreed, only Layer of is built, and writing stays with Properties.

- Layer of is a data node with the input object and the outputs name
  and number. The name is what the project calls the layer.
- NodeContext.collisionLayerOf answers the number, and the new field
  collisionLayers on GraphLookup brings the names to the node.
- layerHolderOf in solids.ts says whose layer counts. An object stands
  for its first collider child, a collider or tilemap for itself.
- Decided here: a collider that is switched off counts too, because
  its layer is set either way.
- Decided here: without a collider the name is empty and the number
  is -1.
- The node is a read, not a run, so it answers at the moment it is
  asked. Right after a Set in the same flow it names the new layer.
- The output number was not asked for. It fits the layer port of
  Properties as it is.

Changing the layer during a run had no test at all so far. Five tests
now hold it in both systems.

Tests:
- Gate: 198 files, 2929 tests (2914 + 15), exit 0
- e2e 1-6: 285 checks passed (06: +2 for block 6z-x)
- Five unit tests for the change during a run: a mover is blocked,
  passes and is blocked again, a ray with a layer filter follows the
  change, and a dynamic body falls through the ground in Play
- Six unit tests for Layer of, three against each system, and four
  cases in the node catalog
- 6z-x finds the node in the palette, checks its ports and logs
  "Ghost" and "1" for the owner's collider in a Play run
- Two counter-probes for the change during a run fail 1 and 4 tests,
  and only new ones, so those places were unguarded before
- Six counter-probes for Layer of fail 2 to 3 tests each. All eight
  ran on stein2, not in the container.
- The browser counter-probe fails 6z-x with "Layer 1" and "1"
- The e2e sum of 1619 is calculated (1617 measured in CI run 276,
  plus 2). Neither the full suite nor the smokes ran for this state.
- Not looked at in the browser: that the layer port of Properties
  shows the same picker as the inspector.

adminandClaude Opus 5.5 d39bf83ea9 Pick the frame's outline when adding a collider to a sprite (#218)
game-maker / gate (push) Successful in 2m49s
game-maker / suite (push) Successful in 13m30s
"Add collider" on a sprite always made a box of the sprite's size,
even when the sprite's picture is a frame that has a collision outline.
The outline then had to be picked by hand as "Frame collision".

- newColliderProps in colliderCommands.ts is the rule as a pure
  function. A sprite whose picture is a frame with an outline gets a
  collider with shape "frame" and that frame. Anything else keeps the
  box of the sprite's size.
- The frame is the one the sprite shows when the collider is added,
  also when only this placement overrides it.
- Decided here, the issue says nothing about size: a frame collider is
  as big as its frame, so a sprite drawn bigger or smaller with the
  same proportions gets the collider's scale set to match.
- Decided here as well: a sprite stretched out of the frame's
  proportions keeps the box, because an outline cannot be stretched
  in one direction.

Tests:
- Gate: 198 files, 2914 tests (2911 + 3), exit 0
- e2e 8,42: 46 checks passed (42: +1 for 42e-ii)
- Three new unit tests in tests/core/collider-parts.test.ts: the
  frame with undo, the scale with an overridden frame, and the cases
  that keep the box
- 42e-ii goes through the context menu: "Frame collision" with scale
  2 on the sprite wearing the wedge frame, a box on a sprite without
  a picture
- Five unit counter-probes fail, 1 to 2 tests each. They ran on
  stein2, not in the container.
- The browser counter-probe fails 42e-ii with shape "box"
- The e2e sum of 1617 is calculated (1616 + 1). Neither the full
  suite nor the smokes ran for this state.
- Vector art has no test of its own, it takes the same branch as a
  whole texture.

adminandClaude Opus 5.5 c1cc80bb45 Add nodes that ask whether an animation still runs (#233)
A graph could start, pause and stop an animation and hear it finish,
but it could not ask in between whether one runs or how far it is.
Two data nodes answer that now.

- Animation playing takes an object and an animation and gives
  playing, progress and time left (s). It answers at the moment it is
  read: right after Play animation in the same pass it says on, and in
  the frame On animation finished fires it says off.
- With Animation at None it answers for the running animation started
  last on the object.
- Animation length gives the seconds of one pass, from the timeline
  and the frame rate alone.
- The rule is a pure function in src/core/model/animation.ts
  (playerStatus, leadingPlayer). The nodes reach an animation's
  length through a new field animation on GraphLookup.
- animationPort is exported so both nodes show the same picker as
  Play animation.

Decided in the issue: a Once (reset) counts as running while it blends
out, and progress and time left also hold for Loop and Ping-pong, at
the place of the playhead. On Ping-pong progress falls again on the
way back and time left counts to the next turn.

Decided here, the issue says nothing on it:
- A paused animation does not count as running. Progress and time
  left stand still.
- One that Stop animation fades out does not count as running, and
  its time left is 0.
- Time left of a Once (reset) includes its blend out. While it blends
  out progress is 1 and time left is the rest of the fade.

Finding, not fixed: on the node the name of the chosen animation
overlaps the output label progress in the same row. That comes from
the fixed node width in NodeView and was seen in the Fit view only.

adminandClaude Opus 5.5 26cc6324af Stop resolving every object in every frame of a run (#287)
World.syncToModel runs after every frame of a run and resolved each
object of the scene anew to compare it with its entity. With 222
entities that was most of the Editor line in the performance panel,
also for entities that are never drawn.

- The world keeps per entity what the model said when it last read
  the object (syncFromModel, spawn) or wrote it. A frame compares the
  entity with that and resolves nothing while both agree.
- A place that differs is written as three numbers.
- A value that differs is written as an override, and that one object
  is resolved again. An override can bring rows of its own, such as a
  sprite's shader.
- The objects of entities that left the run are dropped only in a
  frame in which one left. World.remove notes that.
- Editing during a run works as before: the editor has the model read
  again on every project event, which renews what the world keeps.

One difference: a write to the model that goes past the editor and
does not have it read again now stays. The next frame used to
overwrite it with the entity's state. No code does that, during a run
only the world writes.

Measured on stein2 with a copy of the reference project of #284, ms
per frame: syncToModel alone 0.92 to 0.12 (Node, 600 frames), the
Editor line in the browser 1.14 / 1.20 / 1.29 to 0.25 / 0.25 / 0.27.
Physics and Drawing are unchanged.

Tests:
- Gate: 198 files, 2891 tests (2887 + 4), exit 0
- e2e, full run: 1613 checks passed, exit 0. That measures the total
  that was only computed since #273.
- Smokes: 24 / 19 / 21, exit 0
- Four new unit tests, no new e2e check: 60 unchanged frames resolve
  nothing, an edit during the run arrives and stays, an override with
  rows of its own is seen with them, container content in an editor
  run is written into the instance edits once
- Seven counter-probes fail, 1 to 4 tests each

adminandClaude Opus 5.5 cfd288c4b7 Halve the frame time of a playing scene with a tilemap (#284)
The performance panel showed Physics and Editor as the large parts of
a frame in a scene of 222 entities. Nearly all of it came from a
tilemap that only stands there.

- Whoever writes cells in place now says so with cellsChanged. Only
  then does cellsVersion compare the content. The comparison ran about
  60 times per frame and was the largest single item at 14 percent.
- The four writers call it: the painter during and at the end of a
  stroke, PaintTilesCommand on execute and on undo. A new writer that
  forgets it stays invisible.
- The game view is drawn once per frame in play. With an animated tile
  in view it was drawn twice, once by the run and once by animate().
  animate() now gets the redraw count from the start of the tick.
- TilemapField builds the geometry of a mesh only when its source
  changes: the cells, the tile size, the origin or the image. For that
  groupByTile and layerRows return the same objects for the same list.
- PhysicsSystem skips a tilemap whose source and switch are unchanged.
  The switch is kept because a map that starts switched off would
  otherwise have dead colliders once it is switched on.
- World.syncToModel looks entities and assets up in a map per pass
  instead of a linear search per object.

Measured on stein2 with a copy of the reference project, ms per frame:
Physics 2.64 to 0.97, Drawing 6.89 to 2.56, Editor 1.95 to 1.31.

Left open: syncToModel still mirrors every entity every frame. That
is its own issue.

Tests:
- Gate: 198 files, 2887 tests (2883 + 4), exit 0
- e2e 1-17,28,33,39-43,59: 810 checks passed, 40 has +3
- Smokes: 24 / 19 / 21, exit 0
- Three unit tests wrote cells directly and now call cellsChanged
- Eleven counter-probes fail. Two did not at first: the stroke needed
  a check of its own, the physics test has to start with the map
  switched off. That last one was repeated on stein2 only.
- e2e total 1613 is computed, not measured in a full run

adminandClaude Opus 5.5 6491888f56 Stop offering private variables as new animation rows (#270)
A behavior variable switched private is hidden from the placed object
and from the Properties node, but the row dialog of an animation kept
offering it. Rows that exist already stay as they are, as decided in
the issue.

- offeredDefs in src/core/model/animation.ts is what the dialog offers
  now: what the target can animate, less private variables and less
  what another row animates already. The filter moved there from
  RowDialog.ts, so it can be tested without the editor.
- animatableDefsOf is unchanged. The label and the runtime read it, so
  a row on a variable that went private keeps playing and keeps its
  label.
- Deviation from the proposal: under Change target the row's own
  variable stays on offer, private or not. The dialog would open with
  no property and a disabled button otherwise. Other private variables
  are not offered there either.
- The command does not refuse a private variable. Only the dialog does
  not offer it.

Finding, not fixed: e2e 56 fails when it runs alone, in 56a-ii from
#257 (typing "9" did not arrive: focus is BODY). With 55 before it the
module passes, so a full run does not show it. It was not measured on
HEAD without this change.

Tests:
- Gate: 198 files, 2883 tests (2882 + 1), exit 0
- e2e 55,56: 27 checks passed, 56 has +56e
- e2e 25: 31 checks passed, it uses the same dialog
- Three unit counter-probes each fail the new test
- The browser counter-probe fails 56e, mood shows up in the dialog

adminandClaude Opus 5.5 5e21d473a4 Fix references into nested placements and on asset delete (#285, #286)
Two findings from #269. A reference from a container into a placement
nested in it was dead from the start, and deleting an asset left
references to the objects it took along showing "(missing)".

- A reference is stored the way its holder shows the object. In a
  container tab that is q~x for content of a nested placement q.
- referenceCandidates translates it when the container is placed: in
  placement r, q~x becomes r~q/x. pathOfId and idOfPath in instance.ts
  do the mapping, objectChoices offers the same spelling the other way.
  The rule holds at any depth.
- Storing q/x as proposed in #285 was dropped. The container tab would
  then have had to translate its own ids.
- No migration. All projects and snapshots hold three references, none
  of them with ~ or /.
- Create container lets a reference to content of a member placement
  follow it. It was left dead before.
- Paste lets such a reference point into the copy. It kept pointing at
  the original before. Both go through the new renamedReference.
- Delete asset records what every holder shows before the cascade and
  clears every reference to an object that is gone afterwards, with
  dropReferencesToGone from #269. The row shows None, undo restores
  the references (#286).

Tests:
- Gate: 198 files, 2882 tests (2873 + 9), exit 0
- Unit object-references: 26 passed (17 + 9)
- e2e 1-17,57: 566 checks passed, 57 has +57i and +57j
- Six unit counter-probes fail between 1 and 3 tests each
- The browser counter-probe fails 57i and 57j as described in the
  issues

adminandClaude Opus 5.5 214218d1b2 Clear references to a template object in every scene on delete (#269)
Deleting an object in a container tab only cleared references inside
the template. Placements in scenes and other containers kept their
instance edit and showed "(missing)" in the inspector.

- shownObjectIds records which objects every holder shows before the
  delete. dropReferencesToGone compares that with the state after it
  and clears each reference that no longer resolves.
- A reference is resolved from its own place with referenceCandidates,
  the same way the runtime does. One rule covers instance edits,
  nested placements and full ids like p~crate.
- A cleared instance edit is dropped when it now says the same as the
  template's own value. Without such a value a marked None stays, as
  if picked by hand, and Reset hands the row back to the template.
- All cleared references come back with a single undo.
- References that were already dead in saved projects stay untouched.

Findings, not fixed here:
- A reference from container D into a nested placement q is stored as
  q~<id>, but the copy is named r~q/<id> in every placement of D. The
  runtime finds nothing, so that reference is dead from the start.
- Delete asset removes placed objects by cascade but does not clear
  references to them.

Tests:
- Unit object-references: 17 passed (13 + 4)
- Gate: 198 files, 2873 tests, exit 0
- e2e 1-17,57: 564 checks passed, 57 has 13 (+1 for 57h)
- Five unit counter-probes and one browser counter-probe fail as
  expected
- e2e total 1607 is computed, not measured in a full run

adminandClaude Opus 5.5 0f6e628616 Check the declared type when a graph writes a typed variable (#271)
A list variable with an item type only kept its shape in the editor.
A graph could write any list into it at runtime, and the List node had
no type at all. Now the declaration decides what a write may store.

- Writing a list into a typed list variable leaves out every item that
  does not have exactly the fields of the type. The rest is written and
  the console names each item that was left out, like Add item does.
- The same rule holds for typed list fields inside a struct variable
  and for lists inside typed items, at any depth.
- A typed struct variable refuses a struct with a field the type does
  not have, and a value that is no struct. A struct with missing fields
  still merges in as before, so a partial Pack keeps working.
- The check runs in the Variables node (own variables and Variables
  assets) and in the Properties node when it sets a behavior variable
  of another object.
- Ports learn their declaration through GraphLookup: what a variable
  declares about its type, and which behavior owns a graph. The rule
  itself lives in the new src/core/graph/typedValues.ts, fitsType moved
  there from SetItem.
- The List node gets a Type setting. With a type its items are shaped
  and marked, follow the struct asset, count when the type is deleted
  and offer Split into fields in For each. The mark never reaches the
  running game.
- A type on a List node holding something other than structs is
  refused with a console line.
- Setting the List node back to None removes the marks, unlike a list
  variable. A node list has no per-item type row, so marked items could
  never be freed there. Undo brings everything back.
- tests/core/kinds.test.ts looked for the value as the first parameter
  of a literal. Type now comes first on the List node, so the test
  finds the value by its key.

Tests:
- Gate: 198 files, 2869 tests (2856 + 13), CHECK EXIT 0
- e2e 55: 19 checks (+55j write at runtime, +2 for 55k List node)
- e2e 54: 16 checks, smokes 24 / 19 / 21

- e2e total 1606 is computed (1603 + 3), no full run

adminandClaude Opus 5.5 9b5eeaab57 Empty a deleted tile's cells on every tilemap (#268)
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).

adminandClaude Opus 5.5 14972d057f Refactoring round 8: hide data files, safe saves, Esc as Cancel (#85)
game-maker / gate (push) Successful in 3m53s
game-maker / suite (push) Successful in 11m55s
Recurring cleanup round over the code since round 7 (bc688f3). The
issue now also asks to fix bugs and small inconsistencies found on the
way, so unlike the rounds before, this one changes behaviour in a few
places. Duplicated code in api went from 23 clones with 228 lines to
none (jscpd, at least 50 tokens). In src it stays at 22 clones with
271 lines, the same before and after.

Bugs:
- nginx served project and snapshot files as they were, so anyone who
  knew a project id could read it without signing in. Every file the
  API writes now goes through AtomicFile (temp file, mode, rename).
  Projects, snapshots, releases, accounts and sessions are 0640, and
  nginx answers 403 for them.
- Any signed-in account could delete a shared image, font or sound,
  which projects of other accounts may wear. Deleting one is now for
  administrators only. The editor never deleted a file, so the
  client's delete is gone.
- Two saves of one project could run at once. The lock file was
  removed after each save, so a waiting save and the next one locked
  different files. The lock file now stays, and deleting a project
  takes the lock as well.
- Bytes that are no picture got a 500 instead of a 422, because the
  error handler also threw for warnings silenced with @.
- A session file was rewritten in place. A request reading it at that
  moment found it empty and was signed out. It is replaced atomically.
- Delete did nothing for a shape picked in the vector art list. Delete
  now goes through removeSelection, one case per kind of selection,
  and a kind without a case fails the type check.

Inconsistencies:
- Escape on a question does what its Cancel does. Cancel on "Delete
  project?" and "Restore snapshot?" leads back to the picker or the
  list like the other questions did, and so does deleting a project.
- Editor texts use American spelling throughout, like the port names:
  48 British spellings in 45 lines (colour, centre, initialised).
- objectName and groupName replace eleven copies of "own name, else
  the asset's" and three of "Group". One copy fell back to the object
  id instead of "?".

Duplicates, dead code, comments:
- routeFiles serves images, fonts and sounds instead of three copies.
  HashedFileStore holds what the three stores shared: keeping a file
  under its hash with its name, listing and deleting. The stores keep
  only which bytes they take and what a record says.
- AtomicFile replaces nine copies of temp file plus rename.
- removeShapes is the one way the canvas, the inspector button and
  Delete take shapes out.
- GraphInterpreter.fire was called by tests only. The 54 calls use a
  helper in tests/helpers.ts now.
- FileStore.delete, HttpFileStore.delete and the PluginApi type were
  unused. A doc comment in actions.ts sat above the wrong function.

Checked and left as is:
- solidCells is used by tests only. It is the per-cell view before the
  merge into rectangles, the one place the largest-scale rule shows.
- An undo checker ran all 124 commands of the unit tests and compared
  the project before and after undo. The only differences are empty
  ports, groups and notes lists where there were none, which the file
  format drops anyway.

Docs:
- README: the check sum.
- Wiki, own commit: API (admin-only deletes, 422, file modes, lock
  file), Home (the "Not yet" list named three things that exist),
  Concepts, Keyboard, Vector art, Architecture and Development, and
  the 38 characters Gitea flagged as ambiguous on eight pages.
- .gitignore: the lock files, and pasted-*.png in any folder, which
  keeps the screenshot archive out.

Tests:
- ./check.sh: 195 files, 2817 tests, exit 0 (+2 for the name helpers).
- PHP: accounts 52 in the web container and 53 in the CI image with
  the race test (+2), snapshots 15 (+1), releases 20.
- Full e2e run: ALL PASSED, 1586 checks (+6 in 12, 47, 49 and 50).
- Smokes jumprun, tetris, actor: 24, 19 and 21 checks. The example
  project files were restored byte for byte afterwards.
- The file stores of HEAD and of this commit give byte-identical
  output for the live folders and for store, list and delete in a
  throwaway folder.
- Counter-checks, all fail as expected: a 500 for bad bytes fails 12,
  no admin check fails 49, removing the lock file again loses saves
  in 3 of 3 runs (151 to 170 of 321), Delete ignoring shapes fails 47,
  Escape that only closes fails 50, and dropping the shape case fails
  the type check (TS2366).

adminandClaude Opus 5.5 bc688f3efc Refactoring round 7: split BehaviorSystem, fewer copies (#85)
game-maker / gate (push) Successful in 3m50s
game-maker / suite (push) Successful in 12m3s
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).

adminandClaude Opus 5.5 4194f3e150 Share a link that plays the game without the editor (#266)
A project could only be played inside the editor, behind the login.
To show a game to someone else there was no way short of an account.
A release freezes the saved project under a random token and serves
it on a page that holds nothing but the game view.

- Menu -> Release... opens a dialog with the state of the release,
  the link with Copy link and Open, Publish or Update release, and
  Take down behind a confirmation.
- Publish saves first and refuses while anything is unsaved, like
  snapshots. Updating keeps the link. Take down kills it, and a new
  Publish hands out a new token.
- The link is play.html?game=<32 hex>. The page needs no session,
  paints Theme.colors.background, zooms with Auto and waits for
  "Click to play" so that sound and keyboard focus are allowed.
- The game always starts in the start scene. Persistent variables
  are stored per link in the browser. Plugins are not loaded, and the
  dialog warns about them and about a project without a scene.
- GET ?r=releases/{token} is the only route besides auth/* that works
  without a login. The public answer carries the token as project.id,
  so the project id stays hidden. Release files are written with 0640
  and nginx does not serve them directly (measured 403).
- Starting, the frame and Load scene moved into runtime/GameRun.ts.
  Play in the editor and the play page run through the same code.
- WorldViewport moved to src/viewport/ and no longer needs the
  EditorState. Pointer forwarding (gamePointer.ts) and setting up
  textures, fonts and sounds (projectFiles.ts) exist only once.
- Vite builds two pages. The play page loads 4 kB of its own code
  plus the shared chunk (Pixi, runtime, drawing, 653 kB) and Rapier,
  without the editor.

Found on the way, not fixed here: data/projects/<id>.json answers 200
without a login because the files are 0644.

Tests:
- ./check.sh: 194 files, 2808 tests, exit 0.
- tests/php/releases.test.php: 20 checks, also added to CI.
- New e2e module 60 with 10 checks, played in a browser without a
  session. Module 46 counts the menu entries and was updated.
- Full e2e run: 1572 checks passed.
- Counter-checks: 3 unit, 2 PHP and 3 browser mutations all fail.

adminandClaude Opus 5.5 94c1055895 Throttle what the editor shows while a game runs (#265)
game-maker / gate (push) Successful in 3m40s
game-maker / suite (push) Failing after 11m9s
With the behaviors fixed, the scene Performance test still ran at
about 23 fps with 500 entities. The rest of the frame went to the
editor: every spawn or destroy rebuilt the hierarchy with all its
rows, redrew the scene view behind the game tab and refreshed every
panel. The game itself is cheap. What the panels show of it now
follows a preset in the project settings.

- New section While playing in the project settings with three
  presets: Live, Balanced and Minimal. Every project reads as
  Balanced, including those saved before the setting existed.
- Live keeps today's behavior. Balanced brings hierarchy and panel
  values up to date 4 times a second and stops redrawing the hidden
  scene view. Minimal updates hierarchy and values only on pause and
  throttles the graph tabs as well.
- The graph and state machine tabs stay live under Balanced. At 4
  updates a second the beads on exec edges stutter, and the tabs
  draw only while on screen. This differs from the issue proposal.
- The game itself is never throttled. Pause, step and stop bring
  every panel up to date at once, and a change of structure that
  falls between two updates is kept for the next one.
- The rule lives in editor/playThrottle.ts as panelPolicy and
  PanelClock. PlaySession asks it after every frame.
- Objects spawned at the top level go into a hierarchy group named

adminandClaude Opus 5.5 a7e793f6de Keep many spawned behaviors from eating the frame
A scene with 200 spawned gold pickups, each with a Pickup behavior of
97 nodes, dropped the game to about 14 fps. The graphs themselves ran
only a dozen nodes per pickup and frame. The cost was the lookup: for
every data input the interpreter searched all edges and all nodes of
the graph linearly and computed the port shape of the node again.

- New module core/graph/graphIndex.ts builds tables once per graph:
  nodes by id, edges by node and port, node types. Port shapes are
  cached as well.
- BehaviorSystem shares one cache between all its instances and
  clears it in syncFromModel. A graph changed during a run applies
  from the next frame on, as before.
- An interpreter without a cache, as in most tests, searches as
  before.

Measured on the scene Performance test (headless per frame, browser
fps on a throwaway copy of the project):

- Headless: about 21 ms down to about 3.6 ms per frame.
- Browser, about 505 entities: 13.6 fps up to 23 fps.
- Browser, about 320 entities: 32.3 fps up to 48 fps.
- After the fix behaviors take about 15 % of the browser profile.
  The rest is the editor mirroring the game into the model and
  rebuilding its panels, which is a separate change.

Tests:

- ./check.sh: 192 files, 2786 tests, CHECK EXIT 0.
- Full e2e run (local): ALL PASSED, 1551 checks.
- tests/core/graph-index.test.ts: 2 tests. The tables return the
  same as the search, in the same edge order. A graph changed during
  a run applies from the next frame.
- Counter-check: without clearing the cache in syncFromModel the
  second test fails with ['before'].

adminandClaude Opus 5.5 5fbc6eb088 Set the order in which event nodes run across behaviors (#264)
game-maker / gate (push) Successful in 3m42s
game-maker / suite (push) Failing after 11m7s
Which of two events ran first depended on hidden lists: the order of
the behavior instances and the order in which nodes were created. A
graph had no way to say that one On update must run before another,
and an On update of one behavior could run before a key event of
another.

- A frame now runs event kind by event kind over all behaviors: On
  disable and On enable, key down, key up, key held, timer, collision
  enter, stay and exit, animation finished, click, mouse wheel and at
  last On update.
- All 17 event nodes have a field Order, a whole number, default 0,
  negative allowed. Within one kind a lower Order runs earlier, no
  matter which behavior holds the node.
- On a tie the current hierarchy decides from top to bottom, then the
  order in which the nodes were created. The old rule that a behavior
  enabled later goes to the end is gone.
- The node shows Order: 5 only when the value is not 0, so existing
  graphs look the same.
- The rule lives as pure functions in core/graph/eventOrder.ts. The
  interpreter can now fire a single event node.

Changes in existing projects:

- An object destroyed in a frame gets no further event in that frame.
  On disable and On destroy still come at the end of the frame.
- New instances get all their On start first, then all On enable.
  Teardown runs all On disable first, then all On destroy.
- State events follow right after the event kind that caused them.
- Four unit tests had fixed the old order and are adjusted:
  two in behavior-events, one in physics-system, one in key-repeat.

Tests:

- ./check.sh: 191 files, 2784 tests, CHECK EXIT 0.
- GM_STEPS=1-6: ALL PASSED, 280 checks.
- Full e2e run (local): ALL PASSED, 1551 checks, measured.
- tests/core/event-order.test.ts: 11 tests for the rule, the field on
  all 17 nodes, order across behaviors, key before update, two nodes
  in one graph, On start, hierarchy after late enable and reorder at
  runtime, state events, save and load.
- e2e 6z-viii, 2 checks with real mouse and keyboard: Order -1 set in
  the inspector shows on the node, and a run logs B, A although B is
  lower in the hierarchy.
- Counter-checks: 5 in unit tests and 1 in the browser, all fail as
  expected. The originals were restored and checked with cmp.

adminandClaude Opus 5.5 0c41cb97b1 Clip the children of an object to a clip area (#260)
game-maker / gate (push) Successful in 3m43s
game-maker / suite (push) Failing after 11m7s
An inventory grid could not scroll, because nothing could cut a child
off at an edge. A game also had no way to hear the mouse wheel. Both
are needed for a scrolling list, a dialog text or a window with more
content than room.

- A new object type Clip area has width and height and turns, scales
  and mirrors with its parent. The size gizmo drags width and height.
- Everything below a clip area, on every level, is drawn only inside
  its rectangle, in the Scene view as in the game. Nested areas cut to
  their intersection. The rule works on a convex polygon, so a turned
  area cuts right as well.
- On click, Is hovered and On mouse wheel do not hit a cut-off part.
  The Scene view does not pick it either.
- In the Scene view the area is a dashed frame that is grabbed only at
  its edge, so a click inside lands on the content. The eye under
  Shape hides the frame. In the game the area is invisible.
- While an object below an area or one of its parents is selected, the
  Scene view shows the cut-off part at 30 % opacity and it can be
  grabbed there. The rule lives in core/properties/clip.ts.
- The Properties node knows the type Clip area.
- The new event node On mouse wheel fires by the rule of On click. Its
  delta counts in notches, positive is down, and a frame's turns
  arrive as one value. It also gives x and y.

Limits:

- Only sprites and texts show the faded rest. Tilemaps and particles
  are cut and can be grabbed when open, but are not shown faded.
- Masks by texture shape are out, as noted in the issue.

Tests:

- ./check.sh: 2773 tests, CHECK EXIT 0.
- Full e2e run (local): ALL PASSED, 1549 checks, measured.
- tests/core/clip-areas.test.ts: 12 tests for the cut rule, scene and
  game, save and load, hits, the wheel with and without owner, the
  notch conversion and the open rule.
- e2e 58, 5 checks with real mouse and wheel: the scene cuts (74 of 74
  red inside, 0 outside), a click on the cut part picks nothing, the
  selected rest is faded and grabbable, the game cuts, one notch
  logs 1.
- e2e 04 and 46 count the object types and the eye rows. They now
  include Clip area.
- Counter-checks: 6 in unit tests and 3 in the browser, all fail as
  expected. The originals were restored and checked with cmp.

adminandClaude Opus 5.5 89aa92d2e3 Put a shader on a text and draw pixel fonts sharp (#169)
game-maker / gate (push) Successful in 4m5s
game-maker / suite (push) Failing after 11m40s
A text could not wear a shader, and a pixel font was always smoothed.
Pixi's Text takes no custom shader. It also shares one texture between
texts of the same content and style, and the filter is not part of that
key, so two equal texts with different filters would overwrite each
other.

- TextPicture rasters a text into a texture of its own and draws it
  like a sprite. Shader, time animation and edge mode work without a
  special path. A new text, font or size rasters again and keeps the
  shader.
- The old texture is dropped only after the shader holds the new one.
  Before, Pixi warned about a destroyed texture that was still bound.
- A text has a Shader row with the shader's property rows below, as a
  sprite has. Overrides, saving, animation and the Properties node
  (type Text) know them. A shader parameter named like an own row of
  the text loses to that row, as on the particle source.
- The font asset has a Filter row, Linear or Nearest. The row existed
  three times already (texture, vector art, pixel art) and is now one
  helper filterRow.
- Nearest rasters the text 8 times finer and cuts every 8x8 block to
  one texel: at least half covered is full, else empty. Chrome on
  Windows smooths canvas text sideways through DirectWrite whatever
  filter we set later. The cut removes those half pixels on every
  system, and the texture stays one texel per world unit.

Found on the way:

- On a font that is no pixel font thin strokes break apart under
  Nearest. For a pixel font at its own size this does not matter.

Not done:

- The preview in the Shader tab does not take a selected text as its
  picture, it shows the test picture then.

Tests:

- ./check.sh: 189 files, 2759 tests, CHECK EXIT 0.
- text-shader.test.ts with 10 tests: rows and name precedence, a
  clamped override, save and load, animation, the font filter, and
  sharpCoverage on a smoothed edge and at the texture border.
- e2e 30 has 7 new checks: red glyphs through the shader picked with
  the mouse, the shader survives a new text, red in the game, soft
  edges under Linear, clean 4x4 blocks under Nearest, and half covered
  texels (Linear 238, Nearest 0).
- Full local run before the Nearest cut: all passed, 1543 checks.
  GM_STEPS=1,30 on the final bundle: all passed, 32 checks. The sum
  1544 in the README is counted from these two runs, not measured.
- Counter-checks fail as expected: in the browser no shader on a text
  fails 30h-30j, an always linear sampler fails the Nearest check, the
  old 1:1 raster leaves 107 half covered texels and fails 30k-ii.

adminandClaude Opus 5.5 ef2600493f Read the pixel size of a texture in a graph (#262)
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.

adminandClaude Opus 5.5 4e6aeb5f72 Query objects in bulk and filter, count or test a list (#259)
game-maker / gate (push) Successful in 3m36s
game-maker / suite (push) Failing after 10m6s
The object queries only ever returned one object: Object by name,
Child by name and Find all stop at the first hit. Getting every coin,
every child or every item that passes a test needed a For each with
its own bookkeeping. These nodes return the whole set as a list of
Object, so For each and Find can use item straight away.

- Objects by name returns every scene object with that name in scene
  order.
- Children by name returns every match below object, nearer levels
  first, the same order as the singular node.
- Children returns the direct children, with recursive all of them
  level by level.
- Objects of asset returns every instance of an object asset or
  container by the same rule as Is asset, spawned ones included.
- All four take a snapshot. Destroyed objects are never in it,
  disabled ones are, as with the singular nodes.
- Find has a Mode setting: First, All, Any and Count. First is the
  default and hides the row, so existing graphs look the same.
- Match follows the mode of its paired Find: done with items and
  indices, done with any, or done with count. An unpaired Match shows
  First, since the pairing only comes from the wiring.
- First and Any stop at the first hit, All and Count walk the list.
- Changing the mode drops edges at outputs the Match no longer has,
  in one undo step. SetNodeParamCommand now cleans the whole graph,
  but only edges that were valid before the change.
- The palette entry "filter" adds a Find set to All with its Match.

Found on the way:

- After adding the filter entry, "find" + Enter picked Filter. The
  entry has node type Find, counted as an exact hit, and the tie went
  to the alphabet. The search now ranks by the entry id. e2e 6z-v
  caught it.

Tests:

- ./check.sh: 188 files, 2746 tests, CHECK EXIT 0.
- find-modes.test.ts with 11 tests, 11 catalog cases for the four
  nodes, the asset input guard now expects 3.
- e2e 6z-vii with 3 checks: filter from the palette, Count picked in
  the inspector drops the items edge, a run logs 2, 2, 2, 3, 4, "0, 2".
- GM_STEPS=1-6: all passed, 278 checks.
- Counter-checks fail as expected: every mode stopping early (2),
  Match ignoring the mode (6), cleanup on the own node only (1), no
  recursion (2), no inOrder (2), old ranking (1). In the browser a
  Match ignoring the mode fails both editor checks.

adminandClaude Opus 5.5 f84defb9b6 Pick an object of the same scene for an Object variable (#258)
game-maker / gate (push) Successful in 3m32s
game-maker / suite (push) Failing after 10m2s
An Object variable could only be set by a graph while the game runs.
A placed object always showed "(null)", although the other objects of
its scene are there to choose from and the runtime can already find
any object by its id. Now the placed object stores a reference to one
of them, and the running game turns it into the real object.

- Stored as {"$object": "<id>"}. The empty placeholder stays as it
  was, so old projects load unchanged and empty still means "(null)".
- The row of an Object variable on a placed object is a dropdown with
  None and every object of the scene, indented like the Hierarchy.
  The same goes for Object fields in structs and Object items in
  lists, also in the Variables and List tabs.
- The behavior asset keeps "(null)". An asset has no scene, so "Apply
  to asset" is gone from Object rows.
- The runtime resolves the reference when the Variables or Properties
  node reads it. A destroyed target reads as null, a missing one shows
  "(missing)" in the row.
- Inside a container only objects of the same container are offered.
  The reference keeps the template id, so every placement finds its
  own copy.
- Deleting the target clears the reference in the same undo step.
  Paste points references inside the pasted group at the copies and
  leaves outside references alone. Create container and Unpack carry
  references along with the new ids.
- A value a graph writes while running stays in the run. The scene
  keeps the picked object, also in "Run in editor".

Found on the way:

- Setting an override coerced every object slot to empty, in plain
  values, struct fields and list items. The shared objectPlace() now
  keeps the reference.

Not done:

- No eyedropper to pick in the scene, the dropdown is enough for now.
- Deleting a template object in the container editor does not clean up
  references in other scenes. They read as null there.

adminandClaude Opus 5.5 e8b3ac0a3b Keep behavior variables private to their own graph (#257)
game-maker / gate (push) Successful in 3m40s
game-maker / suite (push) Successful in 10m56s
A behavior often needs working state such as a timer or a counter.
Until now every variable showed up on each placed object and in the
Properties menu, so the inspector filled up with values nobody should
touch. A private variable works like any other inside its graph but
is not offered anywhere outside.

- Each behavior variable gets a lock switch next to Keep. It starts
  off, so existing projects stay as they are (`privateVariables`).
- A placed object shows no private variable, neither in the
  inspector nor while the game runs. If all are private, it says so.
- Switching a variable to private drops its overrides on every
  placed object in one undo step. Switching back does not restore
  them.
- A running game does not write a private value back as an
  override, and a project change during the run does not reset it.
- `+ Property` no longer offers private variables. A port that
  names one by hand still reads and writes it without a warning.
- The default value of a private variable is read-only in the asset
  inspector. Its shape (name, fields, type, delete) stays editable.
- Keep is now a pin icon instead of a word. With the lock added, the
  header of a list variable had no room left and the lock covered
  `+ Item`.

Not done: the animation track picker still offers private variables.

Tests: ./check.sh -> 186 files, 2711 tests, CHECK EXIT 0.
e2e 1,19,20,21,56 -> ALL PASSED, 119 checks. New module 56 has
7 checks with a real mouse. Counter-checks fail as expected: unit
without the write-back filter, the sync guard, dropping overrides or
loading the flag. Browser with all variables on the object, an
unfiltered menu, or no value lock.

Keep is a choice the author makes per variable. Switching it on for

nobody asked for, and the toggle had to be turned off by hand.

- AddVariableCommand no longer adds a new variable to keptVariables.
  Keep is only switched on by hand.
- Existing projects are unchanged. Their keptVariables stay as saved.

adminandClaude Opus 5.5 38e0f656be Split a struct output into one pin per field (#256)
game-maker / gate (push) Successful in 3m32s
game-maker / suite (push) Successful in 10m45s
Reading one field of a struct needed its own Expand node, even where
the graph already knows the struct type. A split output shows the
fields directly on the node, so a Find … Match test becomes a single
Equals and the wires keep running left to right.

- Right-clicking an output pin offers "Split into <Type> fields" when
  the type is known and "Split as …" for every other struct asset.
  The output is replaced by one pin per field with the field's kind.
- The type is known for typed struct variables, typed Pack/Expand,
  fields of another split and item of For each, Find, Match and Item
  at over a typed list (portSplits.ts).
- Right-clicking a field pin offers "Recombine". Splitting drops the
  edges of the whole output, recombining drops the field edges. One
  undo step brings them back.
- The split is stored as GraphNode.splits and saved with the graph.
  Copy and paste carry it along.
- Field pins follow the struct asset like a typed Expand. A new field
  gets a pin, a removed field loses pin and edge, a renamed field keeps
  its edge. Deleting the asset keeps the last fields. The delete dialog
  counts splits, so it now says "node(s)" instead of "Pack/Expand
  node(s)".
- Renaming a variable carries its split and the field edges along.
- At run time the node still produces the whole value. A field pin
  reads its field like Expand, a missing field reads as empty.
- Limits: outputs only, one level, behavior graphs only.

Tests:
- ./check.sh: 185 files, 2706 tests, CHECK EXIT 0
- e2e GM_STEPS=1-6,54,55: ALL PASSED, 303 checks
- New port-splits.test.ts with 12 tests. e2e 6z-vi with 3 checks
  using a real mouse: split Find.item, wire item.Name into the test
  and Match.item.Amount into the log (logs 7), recombine.
- Counter-checks: without field reads in the interpreter, without
  rename in the split, without moving edges on rename and without
  cleanup on field removal one unit test fails each. In the browser,
  without field reads nothing is logged and without type inference
  the split entry is missing.
- Check total in README: 1520.

adminandClaude Opus 5.5 2aaca01929 Find the first matching item with a Find … Match block (#255)
Searching a list with For each needs the test result wired back into
break on the left of the loop node. The wires then run across the node
and the graph reads badly. Find … Match keeps the whole search flowing
left to right, while the test in between stays a free graph.

- Find takes exec and list and offers item and index. It sets them to
  each element in turn and has no exec output of its own.
- Match reads its bool input match once per element. The first true
  value continues at found with item and index of the hit. No hit or an
  empty list continues at not found with an empty item and index -1.
- The pair is derived from the wiring and stored nowhere. A Match
  belongs to the Find whose item or index its test is built from. Copy,
  paste and undo therefore need no extra code (findBlock.ts).
- An unpaired Find or Match, two Matches on one Find and a Match fed
  by two Finds show a warning on the node. At run time the flow ends at
  an unpaired Find and the console says so.
- Adding Find from the palette places its Match 480 px to the right in
  the same undo step.
- The graph draws a quiet frame behind Find, Match and the nodes of the
  test. Literals feeding the test from outside stay outside the frame.
- The test consists of data nodes only, like the break of For each.

Tests:
- ./check.sh: 184 files, 2694 tests, CHECK EXIT 0
- e2e GM_STEPS=1-6: ALL PASSED, 272 checks
- New find-match.test.ts with 12 tests, 2 catalog cases, e2e 6z-v

- Counter-checks: ignoring the test fails 4 unit tests, no ambiguity

  and no Match from the palette each fail their check.
- Check total in README: 1517.

game-maker / gate (push) Successful in 3m28s
game-maker / suite (push) Successful in 10m48s
A typed global list lost the items the game had added to it. The item
showed up in the inspector for a moment and then was gone again.

- Since #254 the project hands out a typed list as a fresh copy each
  time, with the `$struct` marks stripped.
- While a game runs, every change to the project runs
  `adoptDeclarations`. It took a declared value over when it differed
  from the last one it had seen, compared with `!==`.
- The fresh copy never equals the last one by identity. So the empty
  list from the project overwrote the live list on every project
  change, for example when the game writes something back to the scene.
- The comparison now uses `sameValue`. A real edit to the variable
  during a run still reaches the game.

Tests:
- ./check.sh: CHECK EXIT 0
- New unit test in scope.test.ts, red without the fix.
- e2e 55i: a graph appends to a typed global list, then another asset
  changes during the run. With the fix {"filled":2,"afterEdit":2},
  without it afterEdit is 1 and the check fails.

adminandClaude Opus 5.5 b0d0868f55 Give a list one struct type so every item keeps its shape (#254)
game-maker / gate (push) Successful in 3m28s
game-maker / suite (push) Successful in 10m38s
A list of structs used to let every item carry its own fields. Adding
an item meant typing the same fields again, and nothing kept the items
in step with the struct asset from #253. A list can now name a struct
type for its items, and the asset keeps them in shape.

- A list variable and a list field get the row Items with Mixed, every
  struct asset and Make struct type. Make struct type collects every
  field any item has, so no item loses a field.
- A typed item carries its type under the key `$struct`
  (ITEM_TYPE_KEY). listItems does not count it as a field.
- A list that holds anything but structs refuses a type, also when
  the offending item sits in an override. The console names the list
  and the count, and the list stays as it was.
- In a typed list `+ Item` adds an item with the defaults, without the
  kind menu. Field names are locked, values stay editable.
- The rows of a typed item take their kind from the struct asset
  (declaredKind in InlineList.ts). An asset field shows the asset
  picker instead of a text field, as reported in the issue.
- A struct item in a mixed list gets its own Type row. Switching a
  list back to Mixed keeps the type on each item.
- syncStructTypes brings marked items into shape and carries renames
  into them, also inside overrides and nested lists. One undo step.
- The delete dialog of a struct asset also counts typed lists.
- The game never sees the key. World and sharedState strip it with
  withoutItemTypes and bagWithoutItemTypes, so a struct stays a
  plain object at runtime.
- Add item and Set item get the setting Type. With a type they only
  accept a struct with exactly its field names (fitsType in
  SetItem.ts). Anything else is left out and logged.
- The item indent from #252 is back to its old width, the narrow one
  squeezed the value fields.

Not done: writing a variable does not check the type, and the List
node offers no type.

Found on the way: a test helper in list-of-structs.test.ts called
nodes without params. It now passes the same arguments as the
interpreter.

adminandClaude Opus 5.5 61bbb96a96 Define a struct once as an asset and reuse its shape (#253)
game-maker / gate (push) Successful in 3m30s
game-maker / suite (push) Successful in 10m33s
A struct used to declare its fields wherever it stood. The same shape
in two variables meant typing it twice, and Pack/Expand copied it once
without staying in sync. A Struct asset now holds the shape in one
place, and every struct that picks it as its type follows it.

- New asset type "Struct" (not placeable, group Structs, own icon).
  The inspector shows its fields with name, kind and default value,
  and "Open" shows them in the variables tab.
- Struct variables and struct fields get a Type row: own fields, any
  Struct asset, or "Make struct type". With a type the fields come
  from the asset and cannot be added, renamed or removed there. The
  values stay per variable, overrides on placed objects still work.
- Pack and Expand get the setting Type. With a type their ports are
  the fields of the asset and read-only in the inspector.
- A change to the asset reaches every typed place in one undo step
  (syncStructTypes). A new field arrives with its default. A removed
  field goes along with its port, edge and typed value. A renamed
  field keeps its value in variables, overrides and on ports with
  edges, also through nested types.
- Undo for these edits records plain assignments (Recorder), because
  the reach of a change is not known in advance.
- Cycles such as Loot in Loot, also through another type, are refused
  and not offered in the picker.
- Deleting the asset names how many places use it. Afterwards each
  place keeps its fields as its own.
- Loading reshapes a stale copy in a project file to its type.
- "Make struct type" creates an asset from an existing struct and
  links the place to it.

Differs from the plan:

- A changed default value applies to new fields and newly typed
  places only. Existing values stay.
- Removing a single field shows no warning. Undo brings it back.

Typed lists are left for #254. Lists stay dynamic for now.

Found by e2e: after deleting or renaming the type the inspector did
not rebuild and kept showing the old name. Fixed, the check was red
before.

Tests:
- ./check.sh: 182 files, 2661 tests, CHECK EXIT 0
- GM_STEPS=1,4,21,22,54: ALL PASSED, 176 checks
- 14 unit tests in tests/core/struct-types.test.ts
- New e2e module 54 with 14 checks, real mouse. Module 04 counts
  23 asset types.
- Counter-probes: without the rename pass 4 unit tests fail, without
  reshaping values 8, without the cycle rule 1. In the browser,
  without spreading changes and with + Field despite a type, 3
  checks fail.

adminandClaude Opus 5.5 b90b62886b Put one item into a list, a struct staying whole, with Add item (#250)
A list could only grow through Join lists, and that takes its b apart:
a struct becomes one item per field and a list is joined. A list of
structs such as loot could not grow at all.

- Add item returns a new list with value as exactly one more item. A
  struct or a list goes in whole. The list that came in is left alone,
  like with Set item.
- index -1 or unset appends. Otherwise the item goes in before that
  index. An index outside the list appends, so the value is not lost.
- The rule that an item takes the kind of its slot moved out of Set item
  into fitToSlot. Both nodes use it, Set item behaves as before.
- No e2e check and no browser look. The node is covered by unit tests.

Tests:
- ./check.sh: 180 files, 2634 tests, CHECK EXIT 0
- 7 catalog cases, 4 cases in list-of-structs.test.ts, and index in the
  whole-number inputs of texture-kind.test.ts
- Counter-check: taking the value apart like Join lists fails 3 tests
- This commit alone: tsc and the three touched unit files pass

adminandClaude Opus 5.5 cb8a2d029a Loop over a list and stop at the first match with For each (#249)
Finding the first item that matches took Count, Repeat, Item at and a
Branch, and the loop could not stop once it had found something. A graph
has no lambdas, so the predicate is an input that is read every round.

- For each runs body once per element, with item and index set, and
  goes on at done.
- Its break input is read anew before every round, after item is set.
  Once it is true the loop ends there and that round's body does not
  run.
- done sees the matching item and index with stopped true. Without a
  match it sees no item, index -1 and stopped false, the OrDefault.
- RepeatResult has optional items, stopWhen, stopped and exhausted.
  GraphInterpreter.loop reads them, Repeat runs as before.

Tests:
- ./check.sh: 180 files, 2623 tests, CHECK EXIT 0
- e2e GM_STEPS=1-6: ALL PASSED, 269 checks
- 5 interpreter tests in graph.test.ts, 2 catalog cases
- e2e 6z-iv: the palette creates the node, and a search for
  Name == "Gold" in Axe, Gold, Bow, Gold logs "1true"
- Counter-checks: without the break check 2 unit tests fail, and with
  break not read over its edge 6z-iv fails
- This commit alone: tsc and the three touched unit files pass

adminandClaude Opus 5.5 393b8ec7f9 Build your own easing curve and use it on keys and Lerp (#247)
game-maker / gate (push) Successful in 3m44s
game-maker / suite (push) Successful in 10m25s
The built-in eases cover the usual shapes, but a game often wants its
own: a coin that bounces twice, a door that overshoots and settles.
A new asset type holds such a curve, and keys and the Lerp node can
pick it instead of a built-in ease.

- New asset type "curve": points like in Vector art, x is t and y is
  the value. A new curve is the straight line from (0, 0) to (1, 1).
- One pure evaluation in src/core/model/curve.ts serves the timeline
  preview, the running game and the Lerp node.
- The curve always has one value per t. The end points stay at t 0
  and 1, points cannot pass each other, and a handle that reaches past
  its neighbour is shortened along its direction. Loading a hand-edited
  file applies the same rules.
- Curve tab: click on the line to insert a point that keeps the shape,
  click on free space to put one there, drag points and handles,
  double-click or Delete removes, Alt-click toggles round and sharp.
  Every step is one undo step.
- Presets: all 30 built-in eases plus Linear, fitted with adaptive
  subdivision. Each stays within 0.4 % of the built-in ease.
- Preview: a dot runs along the curve once a second, a second dot
  shows only the value. The Preview button stops it.
- Animation keys get "Curve" under Easing with a curve picker. Lerp
  gets "Curve" under Ease, and its result may overshoot b.
- A missing or unpicked curve runs linear. The inspector says so, the
  node shows it as a problem, and deleting a used curve warns with the
  number of keys and Lerp nodes.

Tests:
- ./check.sh: 180 files, 2612 tests, CHECK EXIT 0
- GM_STEPS=1-6,25,53: ALL PASSED, 309 checks
- New e2e module 53 with 13 checks, all with the real mouse. Expected
  values come from its own Bezier evaluation.
- Counter-checks bite: without Bezier evaluation 4 unit tests fail,
  without handle clamping 2. In the browser, a key that cannot find its
  curve, a click that sets no point and a handle drag that moves the
  point all turn checks red.

adminandClaude Opus 5.5 320d3e27e1 Add a Lerp node that blends from a to b with an ease (#246)
game-maker / gate (push) Successful in 3m23s
game-maker / suite (push) Failing after 9m24s
Every animation in a behavior had to build its interpolation from
Subtract, Multiply and Add, once per axis. The gold pickup in
"Garden of Sacrifices" needed about 30 nodes for that alone. A single
Lerp node with an ease makes those chains one node each.

- Lerp has the inputs a (default 0), b (1) and t (0) and the output
  result. It sits in the data category next to Clamp.
- The Ease setting offers Linear, In, Out and In-out, all quadratic.
  The node row shows it as "Ease: Out".
- t is held in 0..1. A timer that overshoots in the last frame still
  lands exactly on b.

Tests:
- ./check.sh: 178 files, 2583 tests, CHECK EXIT 0
- 7 new cases in the node catalog test. Without the clamp on t,
  2 of them fail.
- e2e 6z-iii (2 checks): typing "lerp" in the palette adds a linear
  Lerp, and picking "Out" in the inspector reaches the node and its
  row. GM_STEPS=1-6: ALL PASSED, 267 checks.
- README check sum is 1459, computed, not counted.

adminandClaude Opus 5.5 53fa63441b Group scene objects in the hierarchy, for the editor only (#241)
game-maker / gate (push) Successful in 3m58s
game-maker / suite (push) Failing after 9m58s
A scene with a hundred crates fills the hierarchy with a hundred rows.
Groups bundle top-level objects under one folder row that folds away.
They exist for the editor only. Parenting, positions and the game do
not see them.

- Model: a scene or container template holds a list of groups, an
  object may carry a groupId. Old projects load unchanged. Loading
  drops empty groups and members that are no longer top level.
- Only top-level objects can join a group. Parenting a member takes it
  out of the group, and Undo puts it back. There are no groups in
  groups.
- Order: treeOrder lists the members together, where the first one
  stands. The same order decides drawing at equal z, in the editor and
  in the game, so the hierarchy and the picture cannot disagree. The
  stored object list stays untouched when grouping.
- Hierarchy: a group row shows a folder icon, the name and the member
  count. Clicking it selects all members and keeps it folded. Selecting
  a single member elsewhere unfolds it. Folding lasts for the session.
- Create with "Group..." in the object menu. A name dialog asks first,
  so creating is one Undo step and Cancel creates nothing.
- The group menu has Select members, Rename... and Ungroup. The object
  menu adds "Remove from group".
- Drag and drop: onto the group row appends, into a gap between members
  inserts there, next to a row outside leaves the group. Dragging the
  group row moves all members as a block. The drop rules live in
  hierarchyDrop.ts as a pure function.
- Copy and paste keeps a top-level copy in the group of its original.
  A container built from group members takes their place in the group.
- Clicking an object that is already selected together with others now
  keeps only that object selected. ListView narrows the selection on
  release, so a drag starting on such a row keeps the selection.

Not checked in the browser: groups in the container tab, "Remove from
group", Ctrl-click on a group row and a drag out of a multi-selection.
The code path covers them.

adminandClaude Opus 5.5 7e829f737e Load every picture of a project ahead so animated tiles don't flicker
game-maker / gate (push) Successful in 3m26s
game-maker / suite (push) Failing after 9m6s
A texture was fetched only when it was drawn for the first time. Until
the file arrived, the tilemap skipped the cell for that frame. An
animated tile whose next step sat in another picture therefore blinked
away once on its first cycle, and sprite animations did the same.

- FileLibrary gets preload(files). It requests every file that is not
  held, loading or known to have failed. Each library reports what it
  holds through holds().
- src/core/model/projectFiles.ts lists the files a project names per
  library: uploaded textures, fonts and pixel art cels.
- App.ts runs the preload on every project event. That covers opening
  a project, new assets and edits from a collaborator.
- A new test hook __gm.heldPictures() reports which textures of the
  project are in memory.

Not done on purpose:
- The tilemap keeps no fallback frame while a step is still loading.
- Sounds still load on first play.

Not checked: the flicker itself was not reproduced in the browser, the
e2e check measures "held in memory". Modules 42, 44 and 47 read
textures from the project and were not run locally.

Tests:
- ./check.sh: 174 files, 2518 tests, CHECK EXIT 0

- 3 new unit tests for preload and the project file list

adminandClaude Opus 5.5 6015869297 Let the scene view hide symbols, names and shapes per asset kind
game-maker / gate (push) Successful in 3m15s
game-maker / suite (push) Failing after 9m33s
The scene view gets crowded once a scene holds many behaviors,
colliders and tilemaps. A new eye button in the topbar opens a list of
all placeable asset kinds, and each row has toggles for what the scene
view draws for that kind.

- The popup lists all 9 placeable kinds from Behavior to Tilemap, with
  the columns Symbol, Name and Shape. It stays open while switching.
- Sprite, Text and Tilemap draw no symbol, so their symbol toggle is
  greyed out. Their name toggle shows a new centred name tag, which is
  off by default.
- Shape exists for Collider and Tilemap. A hidden collider outline is
  neither drawn nor clickable. A hidden tilemap shape removes the
  collision outlines and the paint tint, the tiles stay visible.
- A hidden symbol takes no slot in the ring and draws no dashed link to
  its parent. A name that stays on moves to the centre of the object.
- The setting lives in the project as `sceneVisibility`, not in
  localStorage. Older projects load with the defaults, which match the
  view as it was.
- Switching has no undo step, like the game scale. It only changes the
  view. A change made during Play survives Stop.
- The rules sit in `src/core/model/sceneVisibility.ts`, the popup in
  `src/editor/panels/SceneVisibilityPopup.ts`. Four new SVG icons.

Not covered by a check: symbol off with name on for a kind with a
symbol, Text and Tilemap with names, and the paint tint with shape off.

Tests:
- ./check.sh: 173 files, 2515 tests, CHECK EXIT 0
- e2e 46: ALL PASSED, 17 checks. 46g clicks the popup, lays a small
  tilemap over the crate and removes it again.

  the partial run 2,8,46 came from the module selection.
- 8 new unit tests in tests/editor/scene-visibility.test.ts.
- 4 counter-probes, each fails its test: load ignores the saved value,
  Play skips the saved model, scene view ignores collider shape, scene
  view ignores tilemap shape.

adminandClaude Opus 5.5 0c5ac32b59 Let structs and lists nest to any depth (#239)
game-maker / gate (push) Successful in 3m52s
game-maker / suite (push) Successful in 10m24s
Structs and lists were capped at two fixed levels (list of structs,
struct with a list field). Anything deeper was dropped silently on
load, in node settings and when written to a variable. The cap came
from an early design choice, not from a technical need, so it is
lifted completely instead of adding a third fixed level.

- One kind list NESTED_KINDS replaces ListItemKind and
  StructFieldKind. The flat special cases in listItems.ts are gone,
  every value goes through one recursive path.
- A struct inside a struct is declared, like a top-level struct.
  Values coming in over an edge are brought into that shape. Struct
  items in lists still take their fields from the value.
- New valuePath.ts addresses any nested spot by keys and indices.
  ListSlot.field is now ListSlot.path.
- Field commands (add, rename, remove) take the path to the struct.
  They change declaration, own value and all overrides in one undo
  step, as before on the top level.
- Inspector: "+ Field" offers Struct and List on every level. A
  nested struct is a header row with its own "+ Field", its fields
  are indented one step further.
- List tab: a list item shows "n items" and opens one level deeper.
  The title shows the path, e.g. "Listy · nums · [3]".
- Pack in Pack now writes a struct into a struct field instead of
  text. Objects are kept at any depth and stripped at every exit.
- A list edit in a struct field without an existing object override
  now starts from the shown value instead of an empty struct.
- Old projects load unchanged. Save, load and save again gives the
  same result.

game-maker / gate (push) Successful in 3m15s
game-maker / suite (push) Successful in 9m41s
Destroying a container used to take everything below it along. Now
Destroy can remove just the object itself and pass its direct children
on, so a behavior can keep working with what was inside.

- New input keep children (bool, default off). When on, only the
  object goes. Its direct children move up to the object's parent, or
  to the top level if there is none. Grandchildren stay where they are.
- New output children (object list) with the direct children that were
  kept. It is empty when keep children is off.
- The children keep their place on screen. carriedTransform folds the
  destroyed object's position, rotation and scale into their own, the
  same as reparenting in the editor.
- Behaviors and the rigidbody of the object are always destroyed with
  it and are not in the list. Moved up they would steer or simulate
  the parent.
- World remembers which children it reparented, and syncToModel writes
  their new parent into the scene. A reload of the model keeps it.
- Limit, read from the code only: in the editor run the contents of a
  placed container are not baked. Moved children there last for the
  run only.

Tests:
- ./check.sh: 170 files, 2478 tests, CHECK EXIT 0
- e2e 34 (the module with a Destroy node): ALL PASSED, 21 checks

adminandClaude Opus 5.5 7979b8ff19 Let structs and lists hold objects across behavior runs (#238)
game-maker / gate (push) Successful in 3m28s
game-maker / suite (push) Successful in 10m14s
An object could only live in a dedicated object variable, kept in slots
beside the variable bag. Struct fields and list items could not hold
one, so a spawned object packed into a struct or list was lost. This
replaces the slots with one mechanism for all three places.

- "No object" has one resting form everywhere: {"$object": ""}. A
  running game can tell an object slot from an empty text that way.
- During play the object handle lives directly in the value, also
  nested in structs and lists. objectSlots.ts and the special paths for
  Keep and Properties are gone.
- liveObjects.ts strips objects to (null) at every exit: overrides the
  editor run writes back to the scene, saved values of persistent
  Variables assets, live values in the inspector, and the world
  snapshot of the test hooks (objects as names there).
- A destroyed object reads as (null) through isAlive, alone, in a
  struct field or as a list item.
- "+ Field" and "+ Item" offer Object. The inspector and the list tab
  show a fixed (null) row without input.
- Lists from Raycast all stay objects when written to a variable.
  Before they turned into names.
- A struct that only changes by an object writes no override. A list
  that grows by an object writes [(null)], its length really changed.

Found on the way: CI at 98211a8 failed only in e2e 21d. #237 added
asset to the field kinds without updating that fixed expectation. 21d
now expects ...,animation,asset,object,struct.

No project on the server has object variables, so no old data is
affected.

- 7 counter-probes, each fails 1 to 9 tests. Originals back via cmp.
- Not tested on its own: stripping of inspector live values and the

adminandClaude Opus 5.5 98211a8d54 Let a variable hold an object across behavior runs
game-maker / gate (push) Successful in 3m15s
game-maker / suite (push) Failing after 9m2s
A spawned object was only reachable in the run that spawned it. The
Spawn output could not go into a variable because "object" was a
port-only kind, so the next run had no way back to the instance.

- "Object" is now a variable kind. The reference lives for the run
  only. The file stores the declaration and an empty value.
- The live reference sits in slots beside the variable bag
  (graph/objectSlots.ts), not in it. The bag is the behavior's props,
  and syncToModel would have written an object into the scene.
- A destroyed object, or one from a restarted or left scene, reads as
  nothing. A dead reference is dropped from its slot.
- Keep (#229) hands the slots of kept variables on to the next call
  of a sub-behavior.
- Properties of kind Behavior reads and writes another behavior's
  object variable through the same slots.
- The inspector shows "(null)" for it and offers no input.
- A persistent Variables asset with an object variable shows a
  warning under "Persistent". Saved values never keep the object,
  every run starts it at (null).

Objects inside lists and struct fields are left out on purpose.
Emptiness is checked with Equals against an empty b. A node "Is
valid" does not exist yet.

The test helper graphEditor().variables() now also reads the kinds
of a Variables asset a node points to.

adminandClaude Opus 5.5 923baf2557 Let Spawn take an asset over an edge and find a child by name (#237)
An asset could only be picked as a setting on the Spawn node. It could
not be wired in, held in a variable or put into a list. Finding an
object below the own one needed a scene-wide search by name.

- "Asset" is now a kind like Animation or Sound: port, variable, list
  item and a new "Asset" literal node, with its own cube icon.
- Spawn and Is asset have an `asset` input. It uses the key of the old
  setting, so a saved asset reads as the value of the input and older
  projects keep spawning without a migration.
- New node "Child by name" searches below an object level by level.
  A child wins over a grandchild of the same name. Nothing found or no
  object gives null.

Tests:
- ./check.sh: 168 files, 2453 tests, CHECK EXIT 0.
- 9 new unit tests in tests/core/asset-kind.test.ts, catalog cases for
  Spawn, Is asset, Child by name and the literal.
- e2e 6z-ii (2 checks): node rows and a real drag of the literal onto
  `asset`. e2e 6: 119 checks passed. Spawn checks in 3 and 9 passed.
- Counter-checks: depth-first search fails 1, Spawn reading only the
  old setting fails 3, runtime ignoring the parent fails 1.

adminandClaude Opus 5.5 74b9c60661 Stop marking older sprites as changed after loading (#232)
game-maker / gate (push) Successful in 3m9s
game-maker / suite (push) Successful in 9m36s
Loading filled every missing asset property with its `default`. For
Sort with parent that is `false`, while the gold mark and Reset compare
against `initial`, which is `true`. So every sprite, text and particle
source saved before #232 counted as changed once loaded, and each save
wrote the `false` into the project file.

- normalizeBag leaves a missing key missing when it has its own
  `initial`. It still reads as `false`, so older projects draw as
  before, but they no longer count as changed.
- e2e module 4 failed in CI on three checks since 8b44f97. Its Reset
  click hit the extra Reset of Sort with parent instead of Height.
- The #232 test deleted the key on the object instead of going through
  the load path. It now checks that loading keeps the key missing and
  marks nothing. serialize.test.ts no longer expects the filled value.

Tests:
- ./check.sh: 167 files, 2435 tests, CHECK EXIT 0
- e2e 1-5 chained: ALL PASSED, 141 checks (before the fix the same
  three module 4 checks failed locally, as in CI)
- Counter-check: without the fix the extended test fails

adminandClaude Opus 5.5 1d18862ed6 Give unconnected node inputs the default the node shows (#234)
A new node handed null to every unconnected input that had no port
default, even a Bool. The inspector showed false, 0, "" or an empty
list at the same time, so what the node read was not what the editor
said. 97 of 135 inputs of the built-in nodes were affected.

- inlineValue() falls back to the default the inspector shows. One
  place covers every node, also future ones and saved projects.
- A default list is handed out as a fresh copy per read, so a node
  that edits its input in place cannot change the shared default.
- The node shows the value it reads: an empty text or list as
  (empty), an object or struct input without a link as (null).
  Live values while playing use the same words.
- A key input without a key keeps showing a dash, like the key field
  in the inspector.
- Visible changes in old projects: To text without input gives ""
  instead of "0", Select and First not empty give "" instead of null.

Tests:
- 8 new unit tests in tests/core/inline-defaults.test.ts, among them
  one over all built-in nodes that no typed-in input reads null.
- The e2e check in module 6 reads the rows of an unlinked Name of
  node. The check sum stays the same.
- ./check.sh: 167 files, 2434 tests, exit 0. e2e 6: 117 checks.

adminandClaude Opus 5.5 8b44f97c35 Let a child sort with its parent so its Z stays local (#232)
game-maker / gate (push) Successful in 3m7s
game-maker / suite (push) Failing after 8m51s
An animated or set Z of -1 on a weapon put it behind everything on Z 0,
not just behind the player holding it. A child can now opt in to being
drawn at its parent's place, so its own Z only orders it against the
parent and its siblings.

- New property "Sort with parent" on sprites, texts and particle
  emitters, shown in the inspector right under Z. It is a normal
  property, set on the asset and overridable per object.
- With it on, the rest of the scene sees only the parent's Z and, where
  the layer sorts by Y, the parent's feet. Below 0 the child is drawn
  behind the parent, from 0 on in front.
- It works across levels: a grandchild with the switch hangs on the top
  object of the chain.
- It has no effect under a parent that is not drawn itself (container,
  behavior, camera, collider) or under a tilemap.
- New assets start with it on, saved ones read as off, so old projects
  draw unchanged. For that a schema row now has "initial" next to
  "default". The gold "changed" mark and reset follow "initial", so a
  fresh sprite is not marked as changed. No load migration is needed.
- parentGroups() in drawOrder.ts gives a slot only to the top of a
  chain and inserts the children there. Editor, play mode and picking
  all use it, so they agree.

Tests:
- 10 new unit tests in tests/viewport/sort-with-parent.test.ts.
- 8 existing tests list the sprite rows or defaults and got the row.
- New e2e check 5b-ii clicks the switch and checks order and undo.
- Counter-checks, all originals restored by cmp: switch ignored fails
  7, children not sorted by Z fails 6, no chain fails 1, "initial"
  ignored fails 9, row missing in the inspector fails e2e 5.
- ./check.sh: 166 files, 2426 tests, CHECK EXIT 0.
- e2e 5: ALL PASSED, 13 checks. Check total 1398, computed only.
