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.

adminandClaude Opus 5.5 fae827c087 Let an animation key Z so an object can pass behind another
The timeline offered X and Y as position rows but never Z. The list
of position rows was simply written without it when animations came
in with #97. A swinging weapon could therefore not go behind its
character.

- Z is the third position row, after X and Y, on every placed root
  or object. A scene and a behavior still offer no position.
- Play and preview already read and write any position row by name,
  so the one entry in POSITION_KEYS is all the code change.
- The draw order is sorted on every render, and play writes z back
  into the scene each frame. A keyed Z therefore takes effect at
  once. A blended 4.5 sits above 4 and below 5.

Tests:
- ./check.sh: 165 files, 2416 tests, CHECK EXIT 0.
- 3 new unit tests in tests/core/animation.test.ts: Z is offered
  after X and Y and not on a behavior or scene, a running game moves
  the object from behind to in front of another one, and play,
  scene write-back and preview agree on z.
- e2e 25: ALL PASSED, 29 checks. The new check reads X, Y, Z as the
  first rows of the row dialog. Check sum 1396 -> 1397.
- Counter-check: without z in the list all 3 new unit tests fail.

adminandClaude Opus 5.5 147f8ffbea Let animation keys ease with Sine to Bounce in, out or in-out
A key could only ease quadratically, which makes quick moves like a
sword swing feel soft. Animators know the Penner curves from CSS,
GSAP and Unity, so a key now offers all of them.

- Ten curves (Sine, Quad, Cubic, Quart, Quint, Expo, Circ, Back,
  Elastic, Bounce), each in, out and in-out, next to Linear and Step.
- The inspector shows two fields instead of one long list: Easing,
  and Direction only when a curve is picked. Switching the curve
  keeps the direction. Coming from Linear or Step starts at in-out.
- Old projects keep working. ease-in/out/in-out now read as Quad and
  are still saved under that name. New curves save as cubic-out,
  back-in-out and so on.
- Back and Elastic overshoot on purpose. A number property with min
  or max is clamped in play and preview, so a Back in from scale 0
  does not flip the sprite. trackWriteAt now takes the property
  definition, and animatedKind* is renamed to animatedDef*.
- The timeline marker still shows only the direction.
- In-out is built for every curve from its in-curve and its mirror.
  easings.net uses own constants for Back and Elastic in-out, so our
  Back in-out winds up about 5 % instead of 10 %.

Tests:
- ./check.sh: 165 files, 2413 tests, CHECK EXIT 0.
- 12 new unit tests in tests/core/easing-curves.test.ts: round trip
  of all 30 values, start/end/midpoint of every curve, reference
  values, only Back and Elastic leave 0..1, clamping in play and
  preview, unknown values are rejected.
- e2e 25: ALL PASSED, 28 checks. New 25b-ii (3 checks) clicks both
  fields and undoes the four choices. Check sum 1393 -> 1396.
- Counter-checks, each fails its test: no clamping (2), Quad saved
  as quad-* (2), mirrored in-out wrong (2), curve lookup with `in`
  instead of Object.hasOwn (1), no Direction field (e2e 25).

adminandClaude Opus 5.5 21d7149756 Let a nested behavior without a start node run from On start (#230)
A behavior built as a plain behavior, with On start and no Behavior
start, did nothing when another behavior called it through Run
behavior. The node only showed a warning. Such a behavior should run
as a call too, without the author having to rebuild its entry.

- New callEntries() in nested.ts returns the Behavior start node or,
  when there is none, every On start node. callProblem uses it too.
- GraphInterpreter.call() follows all entries one after the other,
  in graph order, in the same frame and with the same variables.
- Behavior end still returns what reaches it. A call through On start
  has no inputs, because only the start node declares them.
- It is a fallback only. With a Behavior start present, On start
  nodes stay out of the call.
- The node warning now reads "No start or On start node - does
  nothing" and only shows when neither exists.
- Keep and local state machines behave as before.

Tests:
- ./check.sh: 163 files, 2396 tests, CHECK EXIT 0 (before 2392).
- 4 new unit tests in tests/core/nested-behavior.test.ts: the flow
  after On start runs, the return value arrives, several On start
  nodes run in graph order, a start node keeps On start out.
- e2e 19: ALL PASSED, 35 checks. Only the expected warning text
  changed, the check sum stays at 1385.
- Counter-checks: without the fallback 3 tests fail. With only the
  first On start exactly the order test fails.

adminandClaude Opus 5.5 454d202109 Let each variable of a behavior choose whether calls keep it (#229)
game-maker / gate (push) Successful in 3m13s
game-maker / suite (push) Failing after 8m46s
The first version of #229 put a Keep state switch on the Run behavior
node. The user wanted it where the variable is declared instead. Whether
a value lives on belongs to the variable, not to every call site.

- The node switch keepState is gone again. RunBehavior, CallResult and
  nested.ts are back to what they were before #229.
- BehaviorAsset.keptVariables lists the kept names. It lives on the
  asset and not in PropertyDef, because that is the schema of every
  inspector row.
- A variable added from now on starts with Keep on. Variables in
  existing projects start with Keep off, so old projects run unchanged.
- SetVariableKeptCommand flips the switch as one undo step. Add, remove
  and rename carry the list along. Loading drops names that are not
  declared.
- The interpreter keeps only the listed variables, per Run behavior
  node and per object as before. The others start at their defaults.
- Local state machines in a called behavior start empty on every call
  again, as before #229. Global and scene machines are unchanged.
- The inspector shows a Keep button in each variable row of a behavior.
  Its state is part of the asset signature, so a click redraws the row.
  Without that the button kept its old look until the inspector was
  reopened.

Found: the project Garden of Sacrifices still has keepState = true on
the call Player -> Character Movement. It is ignored now. Direction
there predates the switch, so Keep is off until set by hand.

Tests:
- ./check.sh: 163 files, 2392 tests, CHECK EXIT 0 (before 2388)
- tests/core/keep-state.test.ts rewritten, 15 tests
- e2e 19: ALL PASSED, 35 checks. 19c-ii now clicks the Keep button
  of a new variable: on when added, off by a click, on again, off
  after undo.
- Counter-checks, each fails its own test: keep list ignored (2),
  states kept (1), new variable not kept (8), rename drops the list
  (1), no Keep button (e2e 19c-ii).

adminandClaude Opus 5.5 7c70245c79 Let a nested behavior keep its variables between calls (#229)
game-maker / gate (push) Successful in 3m3s
game-maker / suite (push) Failing after 8m39s
A Run behavior call started with fresh variables every time, so a
nested behavior could not count, remember or keep a local state
machine across calls. A new "Keep state" switch on the node lets the
callee resume where its last call left off. It is off by default, so
existing projects run unchanged.

- RunBehavior gets the boolean parameter keepState and its node
  description explains it.
- GraphInterpreter keeps the state in keptCalls, keyed by the call
  path, the chain of Run behavior nodes. Two nodes calling the same
  behavior each keep their own state.
- One interpreter exists per behavior instance, so every object gets
  its own state without further code.
- Local state machines of the callee are kept like its variables.
- resumedVariables() matches kept values against today's
  declarations. A new variable starts at its default, a removed one
  drops out, and one whose kind changed starts over.
- The kept state lives as long as the object in the run. It is not
  written to save games.

Limit: a callee input named keepState collides with the switch. The
same already holds for the name behavior, so it is not caught.

Tests:
- ./check.sh: 163 files, 2388 tests, CHECK EXIT 0 (before 2377)
- 10 new unit tests in tests/core/keep-state.test.ts and 1 new
  node catalog case.
- e2e 19: ALL PASSED, 35 checks, with the new check 19c-ii for the
  checkbox, its click and undo.
- Counter probes: ignoring keepState fails 5 tests, state per
  behavior instead of per node fails 1, dropping the outer path
  fails 1, skipping the kind check fails 1, and without the node
  parameter the e2e check fails.

adminandClaude Opus 5.5 03e7a78c3d Keep a tilemap with outlined solids at 60 fps in scene and play
game-maker / gate (push) Successful in 3m1s
game-maker / suite (push) Failing after 8m33s
A project with three tilemap layers, two of them with collision on
water and hill tiles, ran at 33 to 52 fps. A CPU profile showed that
almost all of the time went into the collision geometry of the map.
It was rebuilt from scratch every frame although nothing had changed.
The animated water makes the views redraw every frame, so the cost
was never skipped.

- New module tilemapMemo keeps what is derived from the cells: the
  tiles of a layer, the blocking cells, the rectangles and polygons.
  It is reused as long as the content stays the same.
- A brush stroke paints into the existing cells object. The memo
  therefore compares the content cell by cell, not the identity.
  The comparison walks two arrays in insertion order.
- Clipped outlines are kept per outline list. The model always
  replaces that list instead of changing it.
- PhysicsSystem no longer rebuilds the shapes of a tilemap each tick
  while its cells, placement and settings are unchanged. Before, it
  also built a JSON key from all world shapes every tick.
- The overlaid layers after Set tile in a run stay stable. Otherwise
  the memo would miss on every call after the first edit.

The #184 work only helped Move and raycasts, not this path.

Measured on stein2 (i5-7500T, HD 630), script time per frame:

- Scene, nothing selected: 17.7 ms, 52 fps -> 5.8 ms, 60 fps
- Tilemap selected: 26.2 ms, 38 fps -> 8.6 ms, 60 fps
- Play: 29.9 ms, 33 fps -> 8.7 ms, 60 fps

About 3 ms per frame remain. The content comparison costs roughly
60 us per 700-cell layer and runs about 40 times a frame. The mesh
geometries in TilemapField are still rebuilt every frame.

Tests:
- ./check.sh: 162 files, 2377 tests, CHECK EXIT 0 (before 2370)
- e2e 1-5 and 39-43: ALL PASSED, 289 checks
- 7 new unit tests in tests/core/tilemap-memo.test.ts
- 5 counter checks (content ignored, no memo, outline by kind only,
  physics always rebuilds, layer settings ignored) each fail their
  test. All originals are back, checked with cmp.

adminandClaude Opus 5.5 af6ac12ab5 Show sharp tile preview labels and paths with tunnels and crossings
game-maker / gate (push) Successful in 3m2s
game-maker / suite (push) Successful in 9m20s
The mask labels under the tile preview sat inside the zoomed board.
Pixi rendered them at 10 px and stretched them with the zoom, and
each label was shrunk to the width of its tile on its own. They came
out blurry and in different sizes. The example map also only showed
a ring, so narrow paths and crossings were never previewed.

- The labels live in their own layer in screen space and are
  re-rendered at the fitting font size on every zoom.
- All labels share one size, at most the 10 px of the theme. Below
  6 px they are hidden.
- A label has two lines: the sides on top, the corners dimmed below.
- The example map keeps the ring cell for cell and adds a network of
  1 tile wide paths below it. It has straight 1xN and Nx1 pieces,
  curves, two T junctions, a crossing and a dead end.
- The map stands next to the grid in a wide panel and below it in a
  tall one. Fit picks the layout with the larger tiles, and only Fit
  changes it, so zooming does not make the board jump.
- The new hook __gm.tile.captions() reports size, scale and lines.

Found on the way: the taller map made Fit zoom out further, and 3
pixel checks on the 16 px terrain tiles failed. The side by side
layout fixed that.

Tests:
- ./check.sh: 160 files, 2364 tests, CHECK EXIT 0 (was 2363).
- e2e 39: ALL PASSED, 29 checks (was 28).
- New unit test: the example map has straights, a curve, a crossing
  with four notched corners, a T junction and a dead end.
- Counter check: with the labels back in the zoomed board the new
  caption check fails (scales [0.648, 1]).
- The e2e sum in the README is now 1381. It is calculated only.

adminandClaude Opus 5.5 5dbac3a8df Add a Select node that picks one of two values by a condition
Choosing between two values meant a Branch with the whole action
twice behind it, for example two Play animation nodes that differ
only in the animation. Every later change had to be made in both.
Select picks the value, so the action stays single.

- Select is a data node with the inputs condition, false and true
  and the output value. It passes on "true" if the condition holds,
  else "false". An unconnected condition counts as false, and an
  empty picked input gives null.
- The ports are named false and true, not a and b, so nobody has to
  guess which input is which. The order false, true follows Unreal's
  Select and Blender's Switch.
- false, true and value share one type through `sharedType`, like
  First not empty. With two Animation literals plugged in, value
  takes their type and fits Play animation directly.
- Both inputs are always evaluated. Data nodes have no side effects,
  so that does not matter.

Tests:
- ./check.sh: 160 files, 2363 tests, CHECK EXIT 0 (before 2356).
- 5 cases in tests/core/node-catalog.test.ts and 2 in
  tests/core/shared-port-type.test.ts.
- Counter checks: with the inputs swapped all 5 catalog cases fail,
  without sharedType exactly the type test fails.
- No e2e change, the sum stays at 1380.

adminandClaude Opus 5.5 ffb5bbe039 Stop a key getting stuck when Shift changes it while held (#227)
game-maker / gate (push) Successful in 3m8s
game-maker / suite (push) Failing after 8m37s
Input remembered keys under KeyboardEvent.key. Pressing a, adding
Shift and letting go sent "A" on release, which matched nothing, so
"a" stayed down until the next release without Shift.

- New rule keyName in src/core/keys.ts lowercases a single character.
  So a and A are the same key, also under Caps Lock.
- Input remembers per physical key (e.code) under which name it went
  down and releases exactly that name. So 1 released as ! is freed
  too, which lowercasing alone does not cover.
- On key down, up and held, Key is down and Axis input compare with
  the same rule. A node that already stores A reacts to a.
- Recording a key in the inspector stores Shift+A as a.
- Limit: holding Shift before pressing 1 still sends !, and a node on
  1 does not react. Nothing gets stuck by it.

Tests:
- 3 new unit tests in tests/core/behavior-events.test.ts: the flow
  from the issue, 1 released as !, and a node on A hearing a.
- Without lowercasing exactly the issue test and the A test fail.
- Without the code memory exactly the 1/! test fails.
- ./check.sh: 159 files, 2340 tests, CHECK EXIT 0 (before 2337).
- No e2e change, the check sum stays at 1377.

adminandClaude Opus 5.5 4b7e8614a8 Keep play start and game view scale in the project (#226)
Both settings lived in the browser's localStorage, so they did not
travel with the project and differed per machine. They now belong to
the project like the symbol scale. There is no migration, old projects
load with the defaults.

- New module src/core/model/playSettings.ts reads playFrom and
  gameScale on load. Unknown or missing values fall back to the start
  scene and 100%.
- src/editor/settings.ts is gone.
- Play starts in the project settings dialog is an undo step
  (SetPlayFromCommand). It is only recorded on a real change.
- The game view scale is saved with the project but is no undo step,
  so Ctrl+Z never undoes a zoom. A scale picked during play is written
  to the stored project and survives Stop.
- Save states of persistent Variables assets (saves.ts) stay in the
  browser on purpose. They are runtime data of the game, not settings.

Tests:
- 6 new unit tests in tests/editor/play-settings.test.ts: defaults,
  save and load, broken JSON, undo of Play starts, scale without undo
  step, scale picked during play survives Stop.
- e2e 03g checks the value in the project, nothing in localStorage and
  no new undo step. 35f also checks project.playFrom. No new checks,
  the sum stays at 1375.
- Counter checks: no write to the stored project in play, no read on
  load, and an undo step for the scale each fail exactly their test.
- ./check.sh: 158 files, 2332 tests, CHECK EXIT 0
- e2e 1-17,28,30,35,38-40,46: ALL PASSED, 752 checks

adminandClaude Opus 5.5 5afb70a92e Let the project set the size of scene view symbols
game-maker / gate (push) Successful in 3m0s
game-maker / suite (push) Failing after 9m27s
Pixel art projects draw at very different sizes, so the fixed 18 px
icons of behaviors, containers and rigidbodies were too big in some
projects and too small in others. The size now lives in the project
settings and travels with the project.

- New field Symbol scale in the project settings dialog, below Play
  starts. It takes 0.1 to 4 with two decimals and defaults to 1.
- The value is stored as project.symbolScale. Older projects load
  with 1, and values out of range are clamped on load.
- Every change is its own undo step through a project command.
- The factor scales the icon size, the spacing of icons that share a
  spot, the label offset and the selection frame of icon-only symbols.
- The footprints in bounds.ts that Fit uses stay as they were. The
  hit area follows the icon, so clicks match what is drawn.
- uiHooks reports the icon size so e2e can measure it.

The e2e sum in the README is 1375. That is 1374 plus one new check,
and 1374 itself has not been confirmed by CI yet.

Tests:
- ./check.sh: 157 files, 2326 tests, CHECK EXIT 0 (before 2320).
- New tests/core/symbol-scale.test.ts with 5 tests (default, save
  and load, clamping, undo, icon frame), one more in
  project-settings.test.ts.
- e2e 46f: dialog opens with 1, 0.5 plus Apply gives a 9 px icon,
  undo gives 18 again. Module 46: ALL PASSED, 13 checks.
- Counter checks: without loading the value the save and load test
  fails. With the icon ignoring the factor exactly 46f fails. Both
  originals restored per cmp.

adminandClaude Opus 5.5 2592873d76 Pull nearest tilemap uvs a tenth of a texel in, 0.02 still showed lines
game-maker / gate (push) Successful in 3m1s
game-maker / suite (push) Successful in 9m30s
At 0.02 texel the lines between tiles of a nearest tilemap were gone at
the zooms tried first, but still showed at others. The user raised the
inset to 0.1 by hand and checked it in the browser.

- A tenth of a texel is still far below half a texel, so the texel
  picked at every pixel centre stays the same.
- The comment names the new value.

Tests:
- tilemap.test.ts follows the value: the inset test expects 0.1/96,
  the sliver test allows up to 0.25 texel from the edge, and the quad
  test checks its uvs to 2 digits instead of 3.
- ./check.sh: 156 files, 2314 tests, CHECK EXIT 0.

adminandClaude Opus 5.5 5bf1ee7a4e Let Equals match a number against a typed number like 130 (#224)
The float tolerance from the last commit never reached the case it was
built for. The inputs of Equals are of type any, and their inline field
is a text field. A typed 130 therefore arrives as the string "130", and
the tolerance only applied when both sides were real numbers. The node
fell back to comparing "129.99999999999997" with "130" as text.

- A number against a text that parses as a number now uses the same
  1e-9 rule as two numbers.
- An empty text does not count as 0.
- Two texts are still compared as text, so "1.0" and "1" stay
  different.
- Compare was not affected, its inputs are real number fields.

Tests:
- 3 new cases in node-catalog.test.ts: 129.99999999999997 vs "130"
  is equal, 0 vs "" is not, "1.0" vs "1" is not.
- Counter-check: with the old rule (two real numbers only) exactly the
  "130" case fails. Original restored and compared with cmp.
- ./check.sh: 156 files, 2314 tests, CHECK EXIT 0 (before 2311).

adminandClaude Opus 5.5 9d6a0aebd3 Let Compare and Equals treat float noise as equal numbers
game-maker / gate (push) Successful in 3m4s
game-maker / suite (push) Failing after 9m47s
A graph that checks "time - late == 6" after On timer (#224) failed,
because the difference comes out as 5.999999999999972. Both values are
sums of measured frame times, and they round along different paths.
The only workaround was a Round node in front of every comparison.

- New helper nearlyEqual in values.ts. Two numbers count as equal when
  |a - b| <= 1e-9 * max(1, |a|, |b|). The tolerance grows with the
  size of the values, so it holds for hours of summed dt.
- Compare uses the rule for all six operators. "<" and ">" only hold
  when the values are not nearly equal, "<=" and ">=" also hold when
  they are. So "==" and ">" are never true at the same time.
- Equals uses the same rule when both inputs are real numbers. Objects
  still compare by identity, everything else as text. The node
  description says so.
- The tolerance is fixed, there is no parameter on the node. Physics
  values come from float32 in Rapier and are not covered on purpose.
- The log display is unchanged and still prints the raw number.

Tests:
- ./check.sh: 156 files, 2311 tests, CHECK EXIT 0 (before 2300).
- 11 new cases in node-catalog.test.ts, including the value from the
  log against 6, growth with magnitude, 6.001 != 6 and 1e-6 > 0.
- Counter-check exact compare: exactly the 8 noise cases fail.
- Counter-check "<"/">" without the exclusion: exactly 2 cases fail.
- No e2e change, the check sum stays at 1374.

game-maker / gate (push) Successful in 2m55s
game-maker / suite (push) Failing after 9m22s
A timer can only fire on a frame. It fires on the first frame past each
due time, so Time.time at that moment is the due time plus up to one
frame. On a display that is not exactly 60 Hz this delay creeps up by
a millisecond every few seconds and falls back to zero once it reaches
a whole frame. The issue saw 82.009 after 82 ticks. The timer itself
does not drift, it keeps the remainder when it fires.

- On timer gets a number output late. It is what is left of the
  timer's clock after taking one interval, so time - late is exactly
  the due time.
- When one long frame catches up several ticks, each gets its own
  late. The first one was due longest ago and is the latest.

Tests:
- New unit test in behavior-events: late 0.125 after a frame past
  1.0 s, 0 on the dot, 1.5 and 0.5 for two ticks caught up in one
  frame.
- Counter-check: late taken before the interval is subtracted fails
  exactly that test. Original restored with cmp.
- ./check.sh: 156 files, 2300 tests, CHECK EXIT 0 (was 2299).
- No e2e change. The e2e modules only wire the exec of On timer.

adminandClaude Opus 5.5 aef1eba917 Stop thin lines between tiles of a nearest tilemap at odd zooms
game-maker / gate (push) Successful in 2m55s
game-maker / suite (push) Successful in 9m21s
At zoom levels that do not land quarter edges on whole screen pixels,
a tilemap whose texture uses Nearest showed one-pixel lines in the
wrong colour. The float uv of a pixel centre right at a quad edge
could round onto the first texel of the neighbouring quarter in the
sheet, which is usually a different tile. Terrain sheets showed it
most, because every tile is four quads there.

- Nearest now pulls the uvs 0.02 texel inside each quarter. That is
  far below half a texel, so every picked texel stays the same and
  pixel art keeps its size.
- Linear keeps its half-texel inset.
- The first draft used 0.01. The user raised it to 0.02 after
  checking the result in the browser.

Tests:
- ./check.sh: 156 files, 2299 tests, CHECK EXIT 0 (before 2298).
- New unit test: every nearest uv sits strictly inside its quarter,
  by less than 0.05 texel. Two older tests now expect the inset.
- Counter-check: with no inset for nearest the new test and the
  inset test fail.
- No e2e check. The user checked the result in the browser.

adminandClaude Opus 5.5 c1a702bc39 Add a terrain autotile kind for 6x4 sheets like TD Plains
game-maker / gate (push) Successful in 3m7s
game-maker / suite (push) Successful in 9m54s
Sheets such as "TD - Tileset - Plains" draw an autotile as a 6 x 4
block: a 3 x 3 nine-slice, a vertical and a horizontal strip and a
single tile on the left, the inner corners on the right. The floor
kind only knew the RPG Maker 2 x 3 layout, so these sheets could not
be used as autotiles at all.

- New TileKind "terrain" with 16 px tiles in a 6 x 4 block. All 47
  neighbour combinations are resolved per quarter, so the renderer,
  the collision and the palette stay untouched.
- Whole tiles are used where the sheet draws them: the 16 side cases,
  the four single notches and the two diagonal pairs. Hand-drawn
  strips and single blocks therefore look as drawn.
- Only the missing cases are composed, for example an edge with a
  notch or two notches side by side. They take the side tile and put
  the notch quarters in.
- A notch also takes the quarter above or below from its notch tile
  when fill would stand there. Tall cliff notches keep their wall.
  On ground and stones fill meets fill, so nothing changes there.
- The label rule for floor and terrain now runs through one notch
  function. Floor still passes the MZ table test.

Not touched: the tile board only refits on open and on Fit. Switching
an open tile to a kind with another tile size leaves it small until
Fit is pressed. That was the case before.

Tests:
- ./check.sh: 156 files, 2290 tests, CHECK EXIT 0 (before 2283).
- e2e 39,40: ALL PASSED, 90 checks (before 86). 39j checks 47 tiles,
  pixels of single, notch, pair and composed tiles, and undo to floor.
- Counter-checks: without whole notch and pair tiles one unit test
  and one e2e check fail. Without the taken quarter one of each
  fails. Originals restored by cmp and rebuilt.
- Check sum: 1363 measured by CI plus 4 is 1367, computed only.

adminandClaude Opus 5.5 d257298bc7 Keep a dragged rigidbody on the mouse while the game plays
game-maker / gate (push) Successful in 2m55s
game-maker / suite (push) Successful in 9m16s
Dragging a sprite with a dynamic rigidbody in the scene view during
play barely moved it. Only a quick drag and release got through. A
dragged object should follow the mouse as if it had no rigidbody and
start from rest when it is let go.

- The scene view reports the dragged objects as held through
  EditorState. The game tick no longer writes its own position over a
  drag position that has not been read in yet. This affected every
  object in play, not only rigidbodies.
- A held dynamic body turns kinematic and is set straight to the drag
  target. Gravity and velocity no longer pull it away between two
  mouse moves, and the "moved directly" warning stays quiet.
- A body counts as held when the object itself, an object above it
  or its rigidbody is dragged.
- On release the body turns dynamic again with linear and angular
  velocity set to 0.

Not changed: a press on an unselected crate still lands on its
same-sized collider (rule from #203). Dragging while play is paused
and in the editor run is untouched.

Tests:
- ./check.sh: 155 files, 2273 tests, CHECK EXIT 0 (before 2271).
- e2e 41 alone: 21 checks. e2e 1-16,39-43: 641 checks, all passed.
- 2 unit tests: a held body stays where the drag puts it and starts
  from rest, also for a grip shorter than one physics step. The tick
  does not overwrite a drag position that is not read in yet.
- 1 e2e check in 41b: the crate is lifted 150 units with the real
  mouse, holds exactly at -3490 for a second, then falls from rest
  (1.3 px, then 5.1 px) with an empty log.
- Counter-checks: without holding in physics the crate falls back to
  the ground and the old warning shows. With the tick writing back
  the unit test fails. Without zeroing, a short grip keeps 490 px/s
  and the test fails.
- Check total 1356 + 1 = 1357, calculated.

adminandClaude Opus 5.5 d444b27fae Let behaviors read and set tilemap cells while the game runs (#135)
game-maker / gate (push) Successful in 2m59s
game-maker / suite (push) Successful in 9m22s
A behavior could move sprites around but had no way to look at or
change the tilemap it was standing on. Doors, breakable blocks and
"is there ground ahead?" checks all need that.

- New nodes Tile at, Set tile, World to cell and Cell to world. The
  conversion honours position, rotation, scale and mirroring of the
  placed map. A small Tile literal node lets a graph compare what it
  read against a fixed tile.
- The layer is picked by name from all tilemap layers in the project
  through a new field kind. "First layer" takes the map's first one.
  Because layer is an input, a text can also be wired in.
- Each placement keeps only its edited cells in liveTilemap.ts,
  layered over the asset's cells. A second placement of the same map
  stays untouched, and the asset itself is never written.
- A read sees a Set tile from earlier in the same flow. Drawing picks
  up the edit at once and neighbouring autotile edges adapt.
- Solids see the edits straight away, so a Move in the same frame
  already hits the new cell. Rapier rebuilds its shapes on the next
  step.
- After Stop the map is back to what was painted. The editor run shows
  the edit in the scene view while it lasts and does not touch the
  project.
- An unwired tilemap input means no map, like Get position. Cells
  outside the grid are refused and done reports false.

Tests:
- ./check.sh: 155 files, 2271 tests, CHECK EXIT 0 (before 2245).
- tests/core/tile-access.test.ts (14), one physics test for a floor
  set at runtime, catalog entries for the five nodes.
- e2e 39,40: all passed, 86 checks (before 81), five new in 40s.
- Counter-checks: collision ignoring edits fails 3 unit tests, the
  solids cache missing same-tick edits fails only the "at once" test,
  drawing ignoring edits fails the 2 drawing checks, the editor run
  not reporting a new tile fails only its check.
- 40s uses a still tile. The animated fixture tile redraws every frame
  and hid the last counter-check at first.
- Check total 1351 + 5 = 1356, computed. CI confirmed 1351 at cb32b4b.

adminandClaude Opus 5.5 abf3b1f618 Pick an existing collider or rigidbody from the object menu (#222)
game-maker / gate (push) Successful in 3m8s
game-maker / suite (push) Successful in 9m52s
"Add collider" and "Add rigidbody" could only create a fresh asset.
Reusing one meant creating a copy by hand, and a new box collider
never matched the sprite it was added to.

- "Add collider…" and "Add rigidbody…" open a second menu at the same
  spot: a search field, "Create new …", a separator, then every asset
  of that kind sorted by name. Enter takes the first match.
- An existing asset is placed as a shared child, not copied. An asset
  the object already carries is greyed out.
- The rule for when the entries are available lives in one place in
  the collider commands. An object without a resolvable asset is
  greyed out again, as with the old canAddCollider.
- "Fit to sprite" in the menu of a placed collider sizes it to its
  sprite and centres it (position 0,0, z kept) as one undo step.
- Fit writes overrides of that placement, not the asset, because a
  collider can now sit on several sprites. A value equal to the asset
  value clears the override instead.
- Fit removes the collider's own scale, swaps width and height near
  90 degrees and gives a circle the radius that fits (min/2). It is
  greyed out for polygon and frame outlines and off a sprite.
- Menu has no submenus, so a second menu opens instead, similar to
  "Add Component" in Unity. That costs one click more than before.

Tests:
- ./check.sh: 152 files, 2234 tests, CHECK EXIT 0 (before 151/2228).
- 6 new unit tests in tests/core/collider-parts.test.ts.
- 3 new e2e checks in 08a: submenu with search and greying, an
  existing collider via search and Enter, Fit on oc2.
- 09, 40 and 41 follow the new labels.
- e2e 1-16,39-41 on the final build: ALL PASSED, 596 checks.
- Counter-checks: no greying, existing asset ignored and fit without
  centring each fail at their own check. Breaking the override rule
  fails 2 unit tests.
- CI confirmed 1345 checks at 2cf7202 (task 265). New total 1348,
  calculated.

adminandClaude Opus 5.5 1aae97b335 Open a sprite's texture or shader from the menus and inspector (#221)
game-maker / gate (push) Successful in 2m52s
game-maker / suite (push) Successful in 8m58s
A sprite's texture and shader were only reachable by hunting for them
in the asset panel. Every place that shows such a reference now leads
straight to it.

- Object menu (hierarchy and scene view): "Open texture" and "Open
  shader" sit right below "Open asset" when the sprite has one. The
  object's own values count, so an overridden shader opens the
  override.
- Asset context menu: the same entries at the top.
- Inspector: every asset field with a value shows its label as a blue,
  underlined link. One click selects the asset, a double click opens
  it. An override stays gold and gets the underline too.
- The first click rebuilds the inspector, so the second one lands on a
  different row. The inspector catches that second click before any
  row sees it.
- New pure rule `references.ts`: the asset behind a reference field. A
  frame leads to its sheet. Kinds without a tab (palette, font, sound)
  get no menu entry.
- `followsPress` in `clicks.ts` keeps the double-click window and
  tolerance in one place.
- `activateAsset` in `actions.ts`: opening means the same everywhere
  as a double click in the asset panel, so a scene also becomes the
  active one. The asset panel uses it too.

Tests:
- ./check.sh: 150 files, 2226 tests, CHECK EXIT 0 (before 148/2214).
- 12 new unit tests: 6 for the reference rule, 4 for the link in
  createFieldRow, 2 for followsPress.
- 5 new e2e checks in 28l-ii: both menus, the link's look, click
  selects, double click opens.
- e2e 1-16,26,28,35,39,40 on the final build: ALL PASSED, 732 checks.
- Counter-probes: no "Open ..." entries, no underline and a second
  click never recognised each fail exactly at their checks.
- Check total 1341 (CI counted 1336 at fd6af84), computed.

adminandClaude Opus 5.5 ceaa44e5b8 Add roles and a user management tab for admins (#180, #179)
game-maker / gate (push) Successful in 2m50s
game-maker / suite (push) Successful in 8m57s
Until now every account could do the same, and managing accounts
meant running make-user.php on the server. Accounts now carry a role,
and admins get a tab in the editor to create, rename, re-role, reset
and delete accounts. Both issues share the same server files, so they
land in one commit.

#180 Roles:
- Every account is admin or user. A missing or unknown role counts as
  user, on the server and in the client.
- auth/session and auth/login return {user, role}.
- Auth::requireAdmin() answers everyone else with 403.
- make-user.php takes the role as a third argument. Without it an
  existing account keeps its role, so a password reset from the CLI
  never demotes an admin.
- Admins see and save other users' projects like their own. Saving
  keeps the original owner.

#179 User management:
- The account menu gets "User management" (admins only) and "Plugins"
  (everyone). Both open the same closable tab, accounts on top and
  plugins below. The fixed Plugins tab is gone.
- Per account: Rename, Role, Password (no old password needed) and
  Delete with a confirmation. "New user..." creates one.
- Each account lists its projects with an Open button.
- Delete is refused while the account still owns projects.
- Renaming moves the projects along and ends every session of the
  account. transfer takes the same lock as save.
- On their own row an admin can only set the password. The last admin
  cannot be demoted or deleted. The server enforces both.
- The account rules live in AccountRules.php and accountRules.ts as
  pure functions, so they are testable without a server.

Findings:
- At 1280 px the Delete button reached past the column edge and was
  not clickable. The name column is flexible now, and module 49 checks
  the layout.
- The server lets an admin delete other users' projects, but the
  editor has no button for it yet. Left open in the issue.

Tests:
- ./check.sh: 148 files, 2214 tests, exit 0 (was 147 / 2204).
- New tests/php/accounts.test.php, 51 checks, plain PHP. CI runs it
  as its own step in the gate job, the host has no PHP.
- New e2e module 49 with 18 checks. CI creates the e2e-admin account
  in serve.sh. Modules 14, 38, 46 and the scaffold follow the new tab.
- e2e 1-16,37,38,45,46,49: all passed, 581 checks.
- Counter-checks: owner on save, admin view, default role and self
  delete in PHP fail 7, 5, 5 and 1 checks. Unchecked requireAdmin,
  a wider column and the caller as owner each fail exactly their
  e2e check.
- Check sum 1314 -> 1333 (+1 in 38, +18 in 49), computed.

game-maker / gate (push) Successful in 2m48s
game-maker / suite (push) Successful in 8m46s
PhysicsSystem had 940 lines. The step logic shares its state with
the engine handles of parts and bodies, so a separate class would
need almost the whole system as its interface. That part stays. Two
pieces without own state move out instead. Behaviour is unchanged.

- passesOneWay in oneWay.ts is the one-way rule as a pure function.
  It can now be tested without Rapier.
- bodyGeometry.ts holds the collider shapes and the pose maths.
- PhysicsSystem is down to 820 lines.

Tests:
- ./check.sh: 146 files, 2199 tests, CHECK EXIT 0
- 5 new unit tests for the one-way rule without an engine.
- New tests/core/body-geometry.test.ts: a capsule turned by 90
  degrees went unnoticed before. Both tests fail against that bend.
- Counter-checks on landing hold and teleport detection fail in
  3 to 6 tests each.
- e2e 1-28,31,36,39-43 on the final state: ALL PASSED, 1060 checks
- Each of the four #215 commits was checked green on its own in a
  scratch worktree: 2190, 2192, 2192, 2199 tests.

adminandClaude Opus 5.5 487b3aa5b4 Painting over identical tiles no longer adds an empty undo step (#212)
game-maker / gate (push) Successful in 2m45s
game-maker / suite (push) Successful in 8m43s
A rectangle drawn over cells that already hold exactly that tile
pushed a command that changed nothing. Undo then seemed to do nothing
and the project was marked as modified. PaintTilesCommand.changes()
was meant to prevent that, but nothing called it since #128.

- New paintTiles() in tilemapCommands.ts returns the command for a
  finished stroke or fill, or null when no cell changes. It is the
  first caller of PaintTilesCommand.changes().
- All three paint paths in the Scene View go through it: brush and
  eraser, rectangle (both in endStroke) and flood fill (fillFrom).
- Flood fill was not affected, because floodFill already returns []
  for the same tile. The guard is there anyway, as the issue asked.
- A rectangle that changes even one cell stays a normal undo step.

Tests:
- ./check.sh: 145 files, 2190 tests, CHECK EXIT 0 (before 2187).
- 3 new unit tests in tests/core/tilemap.test.ts: same rectangle
  twice gives no command, a wider rectangle still does, a fill that
  finds nothing gives no command.
- 1 new e2e check in 40d: the same rectangle again, then one undo
  must take 9 cells to 0. A redo restores them for later blocks.
- GM_STEPS=39,40 on the final build: ALL PASSED, 81 checks.
- Counter-probe with changes(...) || true: exactly the two unit
  tests fail, and in the browser exactly the new check fails with
  {"afterUndo":9}. Original restored via cmp (IDENTICAL), rebuilt.
- Editor suite check total: CI measured 1312 at 0e85856, new total
  1313 (calculated) in README and wiki.

adminandClaude Opus 5.5 0e8585665a Load the 500 weight and draw missing glyphs as SVG icons (#214)
game-maker / gate (push) Successful in 2m47s
game-maker / suite (push) Successful in 8m41s
The theme asks for Source Sans 3 at weight 500, but fonts.ts only
loaded 400, 600 and 700. The browser synthesised the 500 text. The
issue comment also asked for the symbols the font lacks to become SVG
icons. A scan of src/ against the font's cmap found 20 such characters
in 30 places.

- fonts.ts loads source-sans-3-latin-500-normal.woff2 as well.
- Menus draw their ticks and the "current" dot as icons. The dot is a
  new MenuItem.current field and no longer part of the label text.
- Inspector action buttons (reset, apply, fit width/height) are
  icons. The menu arrow behind them is the drawn Dropdown chevron.
- Kind marks come from a table in markIcons.ts. Picture kinds use an
  icon, # and Aa stay text because the font has them.
- Scene marks in the asset panel, sound play/stop and the transition
  arrows are icons too.
- Apply is an icon although the font has the arrow. It sits next to
  the reset icon and would look different as a glyph.
- A new Icon widget draws on redraw like Button, so Node tests need no
  DOMParser.
- Tests find icons through the SVG id. The new hook
  __gm.locateIcons(id) and the harness helpers findIcon/clickIcon
  replace locate() on the old characters.

Findings:
- Weight 700 is loaded but the theme never uses it. Left as is.
- The old scene-mark check in module 35 accepted any play glyph on
  screen. It now checks the mark on the start scene's row.
- Module 44 needs the textures from module 37 and fails without it.

Tests:
- ./check.sh: 145 files, 2187 tests, exit 0 (before 144 / 2143).
- New tests/ui/fonts.test.ts: every theme weight is loaded, and every
  character in src/ exists in every shipped face. The cmap reader
  matches fontTools (231 characters).
- Icon tests cover the 19 new files. Each kind mark is either an
  icon or text, never both.
- e2e 1-16,22,30,34,35,43,44: 586 green, 0 FAIL, then 44 stopped
  for lack of module 37. e2e 1-16,37,44,47,48: 618 green.
  e2e 1-14 on the final build: 454 green.
- Two new e2e checks: loaded weights in 14, a reset icon pixel in 04.
- Counter-probes all fail as expected: 500 removed, a play glyph put
  back, the struct icon removed (one unit test each). In the browser,
  500 removed and reset icon hidden fail exactly the two new checks.
- Editor-suite check sum 1312 (1310 measured by CI at 056a622, +2).

adminandClaude Opus 5.5 056a622524 Refactoring round 6: shared sheet canvas, fewer copies (#85)
game-maker / gate (push) Successful in 2m57s
game-maker / suite (push) Successful in 8m55s
Recurring cleanup round. Behaviour is unchanged. Duplicated code in
src went from 27 clones with 299 lines to 6 clones with 56 lines
(jscpd, the two identical OFL licence texts not counted).

- SheetCanvas is the new base of the texture, pixel art and vector art
  canvases. It holds background, mask, hint, panning, wheel zoom, fit,
  view save and restore and the screen mapping. Pixel art keeps its
  whole-pixel panning and fixed zoom steps.
- mixColor in src/core/util/color.ts replaces three copies in
  animation, gradient and particles. It clamps t like the particle one.
- fingerprint now lives once in generated.ts, next to the revision
  contract from #185.
- MoveCommand next to RenameCommand is the base of the three reorder
  commands for tile pictures, tilemap layers and vector shapes.
- The two raycast nodes share inputs, settings and filter via rayOf.
- canvasRect() lives once in AssetTabEditor.
- Removed unused code: findPixelArt, isDrawableShape,
  GeneratedPictures.has and SnapToggle.snapping. Tests now check the
  same things through equivalent paths.
- 38 values used only in their own file lost their export.
- Three comments that told history now describe the current state.
  The bundle stayed md5-identical for those edits.
- README lists vector art, pixel art and palette, and links the two
  wiki pages.

Findings:
- PaintTilesCommand.changes is meant to prevent empty undo steps but
  has not been called since #128. The rectangle tool therefore records
  a no-op undo step when it paints the same tile over itself. Left as
  is, because fixing it changes behaviour.
- No test covered middle-click panning in any sheet tab before. 13f
  and 48a now check it.
- The default values of the ray inputs were untested. Length 1000
  could become 10 without a red test. tests/core/raycast.test.ts now
  covers it.
- CI measured 1308 editor checks at d7c0b7c, not the 1307 counted for
  #164. The sum is now 1310 (1308 + 2), computed.

Tests:
- ./check.sh: 144 files, 2143 tests, exit 0 (before 2142).
- e2e 1-16,37,39-43,47,48 fresh: ALL PASSED, 729 checks.
- e2e 1-13,47,48 with the new checks: ALL PASSED, 518 checks.
- Counter-checks, each restored via cp and cmp: halved panning fails
  both new pan checks; unclamped mix fails 1 test, no blue channel 3;
  coarser hash 3; broken reorder undo 2; triggers setting forced on 2;
  bent ray length 1.

game-maker / gate (push) Successful in 2m43s
game-maker / suite (push) Successful in 8m40s
A shared variable or machine used to live either per object or for the
whole run. Levels need a third lifetime: shared like global, but built
fresh from the declarations whenever a scene is loaded.

- New scope `scene` for Variables assets and state machines. A missing
  field keeps the old meaning: `global` for assets, `local` for
  machines, so existing projects do not change.
- Returning to a scene that was visited before is fresh as well. There
  is no memory per scene.
- A `scene` machine announces its start state again after a scene swap,
  so `On state entered` in the new scene hears it. A global machine
  stays quiet because it never left its state.
- The rule lives in two pure functions in `sharedState.ts`
  (`carriedForward`, `restartedAssets`). BehaviorSystem only calls them.
- The inspector shows a Scope dropdown on Variables assets and a third
  step on the machine dropdown, with a note on what `scene` means.

Decisions:
- `scene` and `persistent` exclude each other (variant A). The choice
  dialog was cancelled, so this is an assumption to revisit. A
  scene-scoped asset hides the Persistent switch, and switching to
  `scene` drops the flag (undo restores it). The guard sits in
  `isPersistent` itself, so no path can save values the scope throws
  away anyway.

Findings:
- `clickText('Scene')` hits the Scene tab, not the menu entry. One e2e
  check was red because of that, and its partner was falsely green
  because it compared `undefined` with `undefined`. Both use `clickLast`
  now.

Tests:
- ./check.sh: 144 files, 2142 tests, CHECK EXIT 0 (before 143 / 2133)
- 9 new unit tests in tests/core/scene-scope.test.ts
- e2e 32 fresh: ALL PASSED, 17 checks
- e2e 1-3,17,18,26,32,35 fresh: ALL PASSED, 213 checks
- 3 new e2e checks (35: scene-scoped asset resets on swap, 32h: dropdown,
  note, hidden Persistent switch)
- Counter-checks bite: ignoring `restarted` fails 2 unit tests and the
  new check in 35, the old announcement rule fails 1, dropping the scope
  guard in `isPersistent` fails 1. Originals restored, cmp IDENTICAL.
- Check sum 1307 (1304 + 3) is computed. Last CI measurement: 1293.

adminandClaude Opus 5 6e3e8d23c5 Combining vector shapes keeps the curves it did not cut (#208)
game-maker / gate (push) Successful in 2m44s
game-maker / suite (push) Successful in 8m42s
Until now every boolean operation on vector art threw the curves away.
The shapes were flattened into line segments, the operation ran on those
segments, and the result came back as a polygon. A circle that nothing
even touched came out of an Exclude with 40 corners instead of its four
points and handles. Now the result carries the original curves again,
and only the edges the operation really drew stay straight.

- While flattening, every sample point remembers which curve it came
  from and where on that curve it sits. The operation runs on the same
  segments as before, so nothing about the boolean result changes.
- When a run of result points walks along one of those curves, that
  piece is cut out of the original curve again with de Casteljau. This
  is an exact cut, not a fit through the points.
- An edge whose two ends sit on the same curve but whose middle does
  not follow it stays straight. Without that rule a cut-off cap would
  bulge back into the shape.
- A closed contour keeps at least three points, so a lens shape does
  not collapse into two.
- The rule lives in its own module, src/core/model/vectorCurves.ts.
  vectorBoolean.ts only hands it the table of sampled points.

Findings:

- The two intersection points themselves sit up to 0.09 canvas pixels
  off the original curve. Clipper cuts the flattened segments, not the
  curves, so this was the case before as well and stays inside the
  0.2 px sampling tolerance.
- Refining those points with Newton steps on the curve was measured and
  gave nothing back (0.02952 px instead of 0.02978 px), because the
  error is in the intersection itself and not in the estimate. The code
  was removed again.
- Theme.ts rowHeight 22 -> 24 is in this commit. The change is not mine,
  it was already in the working tree; gate and module 47 are green with
  it.

Tests:

- ./check.sh: 143 files, 2133 tests, exit 0 (was 2127)
- e2e module 47 on a fresh seed: all passed, 59 checks (was 57)
- 6 new unit tests: untouched circle, untouched side plus a straight cut
  edge, a cut in the middle of a curve, a chord crossing one curve
  twice, two overlapping circles, the three point minimum
- 2 new e2e checks in block 47p: point count and handles from the model,
  plus a pixel pair on the round edge
- Four counter-proofs, all bite: no reconstruction -> 5 unit tests and
  the e2e check fail with 35 points and nothing curved; no chord test ->
  the cap bulges back to 28.28; no three point rule -> the lens test
  fails; handles halved -> the pixel check reads background

adminandClaude Opus 5 d7a2521ca7 A port can take its type from what is plugged into it (#207)
game-maker / gate (push) Canceled after 1m8s
game-maker / suite (push) Canceled after 1m8s
Until now every port of "First not empty" was grey and typeless, so the
editor could not tell you what actually travels through the node. The
output is now typed as soon as both inputs agree, and every any-input is
painted in the colour of its own edge. Nothing changes at runtime.

- A NodeDef can declare which of its ports carry the same value
  (`sharedType: { inputs, outputs }`). The rule itself lives as a pure
  function `agreedType` in `src/core/graph/portTypes.ts`.
- Only the output inherits. It becomes the shared type when every input
  of the group is connected and they all carry the same type, otherwise
  it stays `any`.
- The inputs stay `any` on purpose. `canConnect` checks against the port
  type and a busy input is replaced by the new edge, so a typed `a`
  could never be re-plugged with a text without disconnecting first.
- Chains do not propagate. When looking up what feeds an input, a node
  of the same kind reports the `any` it is registered with, so two of
  them in a row stay untyped and a data cycle cannot ask itself in a
  circle.
- An edge that the new type makes invalid stays where it is and turns
  red. `EdgeLayer` already paints a mismatching edge with `danger`,
  nothing is disconnected on its own.
- New `PortDef.paintType`: colour only, never truth. It is set in
  `drawnDef` and read in `NodeView.redraw`, so `canConnect`, the
  interpreter and the compiler keep seeing `any`. Every connected
  any-input is painted, not just members of a `sharedType` group; ghost
  ports keep their hollow red look.
- The pin now matches the edge that ends in it, because both take the
  colour from the resolved output type of the neighbour. Mixed sources
  therefore show two colours, which explains why the output stays grey.
- New hooks `__gm.graph.portTypes(id)`, `__gm.graph.edgeColor(id)` and
  `__gm.themeColor(name)`. `portTypes` reports type and paint colour
  separately so the type checks do not silently become colour checks.

Findings:

- `resolveDef` only appends derived ports to the registered ones, so a
  fixed port cannot be retyped that way -- it would appear twice. The
  shared type is therefore resolved before the ports are built.
- Answer 5 of the issue (inline field follows the type) has no case left
  under variant A: an unconnected input stays `any` and keeps its text
  field.
- `Item at`, `Join` and `Equals` do not profit: `Item at` has no
  any-input, the other two have fixed outputs. The next candidates are
  the shader arithmetic nodes, which were left alone.

Tests:

- ./check.sh -> 143 files, 2127 tests, exit 0 (was 142 / 2113)
- GM_STEPS=1-6 fresh -> ALL PASSED, 245 checks (was 242), 9 of them new
- 14 new unit tests in tests/core/shared-port-type.test.ts
- 9 new e2e checks in block 6z, one of them a pixel check straight on
  the pin via pixelAt + themeColor
- Counter-probes all bite: filtering unconnected inputs out of
  `agreedType` fails 3 unit tests, ignoring `inherit` fails 1, killing
  the derivation in the bundle fails exactly the 2 expected e2e checks,
  and never setting `paintType` fails 4 unit tests plus the 3 pin
  checks (#bdbdbd instead of #e6a8ff / #6fcf97)
- Screenshot read: `a` pink, `b` green, output `value` grey, edges in
  the same colours
- Check total 1302 (1299 + 3), 1293 was measured by CI at 1a3babf

adminandClaude Opus 5 1a3babf9c5 First not empty gets a setting for what counts as empty (#206)
game-maker / gate (push) Successful in 2m46s
game-maker / suite (push) Successful in 8m46s
The node treated 0, false and an empty text alike, which is right for a
missing behavior parameter but wrong the moment a real 0 travels through
the graph. A setting now says how much counts as empty, so the same node
works for both cases.

- The new parameter "Empty means" has three steps: "Any empty value"
  (the default, the behaviour so far), "Nothing there (0 and false
  count)" and "Only a missing value".
- The default keeps every existing graph as it is, including the common
  setup where an unset animation parameter arrives as an empty text.
- The rule lives in isEmptyValue(value, mode) in values.ts; the node only
  passes the step through. An unknown setting behaves like the default,
  the same way Compare does.
- The node description is shorter because the old one was cut off in the
  inspector.

Findings:

- In the "Nothing there" step a struct is empty only when its fields are
  empty under the same step, so a position (0, 0) stays a real value.

Tests:

- ./check.sh: 142 files, 2113 tests, exit 0 (before 2104).
- 9 new cases in the node catalog table: the edge cases per step (0,
  false, empty text, empty list, position (0, 0), unconnected a) plus an
  unknown setting.
- Two counterproofs hold: letting "Nothing there" act like "Any" drops
  the 3 cases with 0, false and the position; removing the "Only a
  missing value" step drops the 2 cases with the empty text and list.
- Seen in the browser: the node shows "Empty means: Any empty value" and
  the inspector dropdown lists all three steps.

adminandClaude Opus 5 d98c2898b1 A new node takes the first of two values that is not empty (#205)
game-maker / gate (push) Successful in 2m46s
game-maker / suite (push) Successful in 8m38s
A graph that reads an optional value needed a chain of Equals and
Branch just to fall back on a default. The new node does that in one
step: it passes a through unless a is empty, in which case b comes
out. Both ports are any, so it works for numbers, text, lists,
structs and objects alike.

- `First not empty` sits in the data category with two any inputs
  `a` and `b` and one any output `value`. Are both empty, b comes
  out, so the second input doubles as the default.
- `isEmptyValue` in values.ts holds the rule as a pure function:
  nothing connected, 0, an empty text, false, an empty list, and a
  struct whose fields are all empty.
- The struct case is what covers a position: behavior graphs have no
  vector type of their own, so (0, 0) arrives as a struct. `{x: 0,
  y: 2}` therefore counts as set, `{x: 0, y: 0}` as empty.

Findings:

- A real 0 or false on a is passed over. That follows from counting
  0 as empty and is written down in the issue.
- The output stays any. Ports that inherit their type from an input
  do not exist in the graph; `Item at` has the same shape.

Tests:

- ./check.sh: 142 files, 2104 tests, exit 0 (was 2094).
- 10 new catalog cases: a set, a unconnected, 0, "", false, an empty
  list, a position (0, 0), a struct with one field set, an object,
  and both empty.
- Counter-check: with structs never empty and 0 a real value exactly
  those two cases fail, the rest stays green. Originals restored and
  compared with cmp, then rebuilt.
- No e2e check: single data nodes have no e2e coverage here, the
  palette fills itself from BUILT_IN_NODES.

adminandClaude Opus 5 41772e53f7 Variables assets can keep their values from one run to the next (#166)
game-maker / suite (push) Successful in 8m21s
game-maker / gate (push) Failing after 3h5m52s
A game needs a high score or an unlocked level to survive the end of
a run. As agreed in the issue there are no save or load nodes. A
Variables asset gets a switch instead, and the existing Variables
nodes read and write the values as before.

- A "Persistent" checkbox in the Variables inspector. Toggling it is
  one undo step, and absent means not persistent.
- The behavior system loads the saved values at start and writes them
  after every frame that changed one, so a closed tab loses nothing.
- Values live in localStorage per project, not in the project file.
  Another browser or person starts fresh.
- Play and "Run in editor" save apart, so trying a behavior in the
  editor leaves the Play save alone.
- Saved values are read through the current declaration. A removed
  variable drops out, a new one starts from its default, and a changed
  kind is converted.
- "Clear saved values" in the inspector clears this asset in both
  areas. The main menu gets "Clear saved data" for the whole project.
  Clearing takes effect from the next run on.

Decisions:
- The switch covers the whole asset, not single variables. Mixing
  both means two assets.
- A changed default in the inspector shows only after the save is
  cleared. That is what persistent means.

Findings:
- The first e2e run died at "debug hook present" right after a Vulkan
  error from Chrome. The second run passed, so it was a GPU flake at
  start-up.

Tests:
- ./check.sh: 140 files, 2070 tests, exit 0 (before 138 / 2055).
- 15 new unit tests in tests/core/saved-values.test.ts and
  tests/editor/saves.test.ts.
- GM_STEPS=32,46 fresh: ALL PASSED, 24 checks. Six new checks in
  module 32 go through the UI. Module 46 knows the new menu entry.
- Counter-checks both fail as expected. Loading switched off: 2 unit
  tests and 2 e2e checks fail. Editor run writing into the Play area:
  1 e2e check fails.
- Check total 1278 (1272 measured by CI at bbbf341, plus 6).

adminandClaude Opus 5 bbbf34109b Lists duplicate, rename and edit values right in their rows
game-maker / gate (push) Successful in 2m20s
game-maker / suite (push) Successful in 8m25s
Name, opacity and Z each sat in a separate field below or beside
the list. You had to select a row first and then look elsewhere to
change it. Duplicating was a separate button or not possible at all.
Now the row itself carries everything.

- SortableList gets three optional callbacks. onDuplicate shows a
  copy button between the eye and the delete button. onRename opens
  a text field on double click, Enter or a click outside commits,
  Esc cancels, an empty name is ignored. value puts a NumberField
  into the row.
- Dragging on the number changes the value and never moves the row.
  A whole drag is one undo step, the canvas follows live.
- Copy and delete only show on the hovered and the selected row.
  Their space stays reserved, so nothing jumps on hover.
- Pixel layers: copy right above with the same pixels on all
  frames, rename, opacity in percent. The Name and Opacity fields
  below the list are gone.
- Pixel frames: copy right after, replaces the Duplicate button.
- Tilemap layers: copy with cells, Z and visibility, rename, Z in
  the row. The Name and Z fields in the panel are gone.
- Vector shapes: copy at the same place and select it, rename.
- New in core: DuplicateVectorShapeCommand,
  DuplicateTilemapLayerCommand, withLayerDuplicated and copyName
  ("X copy", "X copy 2"). copyName lives in src/core/util/names.ts
  because the model never imports from commands/.

Findings:

- Double clicking a shape that is not selected yet only selects it.
  The first click moves the list up, so the second click misses the
  name. Module 47 selects the row first.

Tests:

- ./check.sh: 138 files, 2055 tests, CHECK EXIT 0 (before 2052).
- GM_STEPS=47,48 (fresh, twice): ALL PASSED, 91 checks (before 86).
- GM_STEPS=39,40,47,48: module 40 green, 47 died on the rename
  check, which was a test fault and is fixed.
- Counter probes: a constant copyName fails the shape and pixel
  layer tests. A dead copy hit fails the copy check in 47.
- Check total 1272 in README and wiki, computed (1266 + 6).

adminandClaude Opus 5 66d6aafbb4 Pixel art can be drawn in its own tab with layers and frames (#130)
game-maker / gate (push) Successful in 2m24s
game-maker / suite (push) Failing after 7m40s
Textures are uploaded files named by their content, so they cannot
be edited in place. Pixel art is therefore its own asset type, like
vector art. Its pixels live in the project and the tab rasters them
into a texture that sprites, tiles and animations can use.

- New asset types Pixel art and Palette. The first pixel art of a
  project gets a palette with the 16 PICO-8 colours in the same undo
  step. Every pixel is a palette index, 0 is transparent.
- Each layer on each frame is its own file data/pixels/<sha256>.px.
  The project only holds the names, so undo swaps names. The browser
  computes the hash and uploads new cels before the project is saved.
- New route POST ?r=pixels in api/lib/PixelStore.php. It answers 201
  and 422 for broken data. data/pixels/ is git-ignored.
- Tools: pencil, eraser, fill (contiguous or all pixels of a colour),
  eyedropper, line, rectangle and ellipse (outline or filled), brush
  size 1 to 8.
- Layers can be added, deleted, renamed, reordered, hidden, faded and
  merged down. Frames can be added, duplicated, deleted and reordered,
  with onion skin and a small playing preview.
- Zoom 1x to 32x in whole steps, grid from 8x, a 3x3 tile preview and
  Resize... with a 3x3 anchor.
- All frames sit side by side in one image. Each frame is a region
  like a cut texture frame, so texture rows offer "Asset / Frame 2"
  and the context menu has Create animation from frames.

Decisions:
- Merging down drops the opacity of the upper layer. Indexed colours
  know no blends.
- Only the last palette colour can be removed. Otherwise the indices
  of every image using the palette would shift.
- Undo stores the whole layer per stroke instead of pixel diffs.
- Alt+click picks a colour. It is a mouse gesture, not a shortcut.

Follow-up issues: #197 import from texture, #198 selection and
flipping, #199 PNG export, #200 more tools.

Tests:
- ./check.sh: 136 files, 2049 tests (before 135 / 2011). 34 new in
  tests/core/pixel-art.test.ts, 4 from the icon tables.
- e2e module 48 fresh: ALL PASSED, 29 checks, console empty.
- Counter-probes bite: five on the unit tests, upload order (2 tests
  fail) and cels not uploaded in the browser (1 check fails).
- Check total 1259 in README is computed (1232 measured in CI + 27).

adminandClaude Opus 5 592ea942d9 Vector shapes can fill with gradients and textures (#186)
game-maker / gate (push) Successful in 2m14s
game-maker / suite (push) Failing after 7m14s
A vector shape could only be filled and outlined with one flat colour.
Shading, glows and patterned surfaces had to be faked with stacks of
shapes. Every shape now has a paint type for its fill and its outline.

- Fill type: solid colour, linear gradient, radial gradient or
  texture. Line type offers the same without texture.
- Colour stops are edited on a bar in the inspector, as agreed in the
  issue. A click on the bar adds a stop in the colour the gradient
  already has there, so adding never changes the picture. At least two
  stops remain.
- The new Paint tool in the tab shows two handles for the selected
  shape: axis start and end, centre and radius, or the corners of one
  texture tile. "Handles: Fill / Outline" picks which paint is edited.
- Moving a whole shape moves its gradients and tile with it. Every
  gesture is one undo step.
- A texture fill always tiles, because Pixi turns a non-repeating
  pattern into a repeating one anyway. When switched on, one tile
  covers the whole shape.
- Only uploaded textures and frames can be a fill, never a drawing.
  A drawing filled with itself would rasterise itself mid-raster.
- The fingerprint of a drawing includes the texture and frame a fill
  points to, so the picture redraws when the image is swapped.

Findings:

- graphics.destroy(true) also destroyed the textures of the fills.
  With a texture fill it deleted the tile slice and the next redraw
  crashed on reading 'scaleMode' of null. It is now destroy().
- The gradient cache destroyed old gradients itself, which gave 20
  Pixi warnings "destroyed while still bound". They are now handed to
  Pixi's texture GC with autoGarbageCollect switched on. The console
  of module 47 is empty again, the last CI log had 0 of them.

Tests:

- ./check.sh: 135 files, 2011 tests, exit 0 (before 134 / 1986)
- npm run build: exit 0
- GM_STEPS=47, freshly seeded: ALL PASSED, 54 checks (before 44),

adminandClaude Opus 5 1116818011 Vector shapes can be combined by union, subtract and more (#187)
game-maker / gate (push) Successful in 2m13s
game-maker / suite (push) Successful in 7m51s
Building a shape out of simpler ones meant drawing the result point by
point. The Vector Art tab now selects several shapes at once and
combines them with a boolean operation into one ordinary shape.

- Ctrl/Cmd+click in the tab and Ctrl or Shift+click in the shape list
  add a shape to the selection. Shift stays pan in the canvas.
- A COMBINE block in the inspector offers Union, Subtract, Intersect
  and Exclude. Subtract removes every upper shape from the lowest one.
- The result replaces the lowest selected shape and keeps its name,
  colours, stroke and place in the order. It is one undo step.
- Curves are flattened to 0.2 canvas pixels, a circle gets about 48
  points. Open lines and single shapes cannot be combined, the buttons
  are off and a hint gives the reason. An empty result is rejected.
- Delete now removes every selected shape, and the selection drops
  shapes that no longer exist.
- The geometry comes from clipper2-ts 2.0.1, pinned. It has no
  dependencies and speaks even-odd directly. Only the engine module
  is imported, the bundle grows by 55 kB instead of 110 kB.

Findings:

- clipper2-js was tried and dropped. It pulls in Angular 15 with a
  high npm audit finding and no fix.
- Pixi finds holes by containment, not by even-odd depth. An island
  inside a hole would be drawn as a hole again. Result rings are
  emitted outer ring before its islands, and a test mirrors Pixi's
  rule.
- A depth sort turned out to be dead code in a counter-check and was
  removed. A pixel check in 47h stayed green without the subtract
  and now checks both colours.

Tests:

- ./check.sh: 134 files, 1986 tests, exit 0 (before 133 / 1968)
- npm run build: exit 0
- GM_STEPS=47, freshly seeded: ALL PASSED, 44 checks (before 39)

adminandClaude Opus 5 3427f84a55 A game can pause itself and set its own time scale (#167)
game-maker / gate (push) Successful in 2m11s
game-maker / suite (push) Successful in 7m48s
Until now only the editor toolbar could pause a running game. A pause
menu inside the game had no way to stop the world while its own graph
kept running, and there was no slow motion.

- Five new nodes: Pause game, Resume game, Is game paused, Set time
  scale and Time scale. Pause and resume take effect on the next frame.
- A game pause stops world time, physics, animations, particles and
  shader time. Only behaviors with the new "Run while paused" switch
  keep running.
- Set time scale 0 freezes the world but graphs keep running, as
  agreed in the issue.
- Play and Stop reset the time scale to 1, Load scene keeps it. The
  pause belongs to the scene, so Load scene and Restart unpause.
- The toolbar pause stays separate and also freezes the menu. When the
  game pauses itself the status line reads "The game paused itself".
- While paused, collision events are not reported, sounds keep
  playing, and the editor run ignores both nodes with a log line.

Findings:
- The first status line was longer than any before and got cut with
  an ellipsis. It is shorter now.
- The e2e harness did not know the key "p". It does now.

game-maker / gate (push) Successful in 2m13s
game-maker / suite (push) Successful in 7m42s
Drawing an outline by hand for every frame of a sheet is slow, and the
outline mostly follows the opaque part of the image anyway. The texture
tab now traces it: one click, a corner budget, and every Frame
collision collider and tile using that frame blocks with the result.

- "Generate collision..." sits in the texture tab header and is off
  while the texture has no frames.
- The dialog has Max points (default 8, 3 to 64), Solid from ... %
  alpha (default 50) and All frames of the texture. A live line says
  what Generate will write, and Generate stays off when nothing is
  solid enough.
- traceCollision walks each island of solid pixels along the pixel
  edges, then drops the least important corners until at most N are
  left and no stair step remains. A slope becomes one straight edge.
- An outline never crosses itself. Where the image would force that,
  the island's convex hull is taken instead.
- Crumbs under 1 % of the frame area are dropped unless they are the
  only island. Holes are not reproduced.
- Existing outlines are replaced. One frame or all frames is a single
  undo step.
- TextureLibrary hands out the sheet's RGBA data, and a pure function
  cuts a frame's region from it.

Findings:
- The wedge in the e2e fixture gets 4 corners, not 3. Its tip is one
  pixel wide in the image, and that real edge stays while corners are
  still free.

Tests:
- ./check.sh: 131 files, 1941 tests, CHECK EXIT 0 (was 130 / 1931).
- 10 new unit tests in tests/core/trace-collision.test.ts, including
  150 random shapes that must all be valid and within the budget.
- GM_STEPS=42, freshly seeded: ALL PASSED, 20 checks (was 16).
- Three counter-probes bite: no hull fallback, no stair threshold,
  dialog ignoring the alpha threshold.
- Check sum 1202 in README is computed (1198 + 4), CI measures it.

adminandClaude Opus 5 f4ec23d3d3 Colliders take a frame's outline and tiles have their own surface (#193)
game-maker / gate (push) Successful in 2m11s
game-maker / suite (push) Successful in 7m33s
Issue #193 asked where friction, bounciness and density of a tile
live. Tiles had a fixed surface (friction 0.5, bounciness 0) and a
collider could not use the outline drawn on a texture frame (#141).
Both gaps are closed here.

- A collider has a fifth shape "Frame collision" with a Frame row.
  The frame is picked like a sprite's texture and stored as the
  value 'frame'.
- The shape is linked, not copied. Redrawing the outline in the
  texture tab changes every collider using that frame, in the editor
  and on the next play.
- The frame centre sits on the collider origin, one image pixel is
  one unit. The shape turns, scales and mirrors like any other.
- Every outline ring blocks. Each ring is split into convex parts the
  same way a polygon is.
- Without a frame, with a whole texture or with a frame that has no
  outline, the collider is drawn red as a box and blocks nothing.
- Move, Rapier, raycast, detection, hit test, drawing and footprint
  all resolve the frame. At runtime an entity looks the frame up
  live in the current project.
- A tile has Friction and Bounciness next to Solid and One-way. The
  rows only show when Solid is on. Defaults and mixing rules match
  the collider. Density is left out because a tilemap never moves.
- Tilemap cells are grouped by surface as well as by one-way angle.
  Ice and stone never merge into one rectangle, and every cell brings
  its surface to Move and Rapier.

Findings:

- A tile with a collision scale below 1 is no longer flush with a
  neighbour of another surface. It is inset there like at an open
  side, the same as next to one-way tiles today.
- A bounce test first measured 0.84. The ball had landed on the hero
  at the origin, not on the tile. On the tile it measures 0.993.

Tests:

- ./check.sh: 130 files, 1931 tests, exit 0 (was 129 / 1917).
- 14 new unit tests in tests/core/surface.test.ts. The Move tests run
  against the editor run and the physics system.
- 3 new e2e checks: 40l (surface rows follow Solid), 42e (collider
  has frame size, a walker climbs the slope in the frame).
- GM_STEPS=1-8,39-43 freshly seeded: ALL PASSED, 376 checks.
- Three counter-probes bite: Move ignores the tile surface (2 fail),
  Rapier ignores it (1 fails), frame shape falls back to a box
  (5 fail).
- Check sum 1198 is computed (1195 + 3), the full run belongs to CI.

adminandClaude Opus 5 3ff7e91dbf Vector art points have four types and the pen draws whole curves (#195)
game-maker / gate (push) Successful in 2m10s
game-maker / suite (push) Successful in 7m29s
The pen only pulled out the outgoing handle of a new point, because
the opposite handle was mirrored only if it already existed. The
first segment of every dragged point was therefore half a curve.
Beyond that bug, a point had no way to say how its handles relate.

- A vector point has an optional mode: straight, corner, smooth or
  symmetric. Missing means corner. The mode is not part of the
  fingerprint, because it changes no pixel, only the next drag.
- Dragging a handle follows the mode. Corner leaves the other handle
  alone, smooth turns it along and keeps its length, symmetric
  mirrors it exactly.
- The pen pulls out both handles mirrored and marks the point
  symmetric. A plain click still sets a point without handles.
- The tab header has a "Point: ..." menu for the last clicked or set
  point. That point is drawn filled. Changing its type is one undo
  step. Text instead of four icons, because the UI kit has no
  tooltips.
- Switching a point without handles to a curved type first grows
  handles along its neighbours. Smooth and symmetric line the
  handles up and keep the rough direction of the curve.
- A point inserted on a curve is smooth. Symmetric neighbours become
  smooth, because the split shortens one of their handles.
- Alt-click still toggles between straight and symmetric.

Found on the way: the old Alt rounding took the point at the other
end of an open line as a neighbour, so its handles came out skewed.
Fixed and held by a unit test.

Existing points with handles now count as corner. Before, every drag
mirrored. No pixel changes, only the next drag behaves differently.

Tests:
- ./check.sh: 129 files, 1917 tests, exit 0 (before 1903)
- GM_STEPS=47, freshly seeded: ALL PASSED, 39 checks (before 32)
- Check sum 1195 in README and wiki is computed (1188 + 7), CI
  measures it
- Counter-checks: pen without 'symmetric' fails 3 checks, no smooth
  branch fails 1 unit test and 1 e2e check

adminandClaude Opus 5 6371576d37 A vector art asset is a picture now, which is stage 2 of #129 and the first stage that shows something in the browser: the asset sits in the picture picker, a sprite carries it in its Texture row and what the sprite shows has been rasterized from the shapes, the generator of #185 being registered for the type vectorart - installVectorArtPictures(app.renderer) hooks the source (core) and the generator (viewport) in once per page from App.ts, by a call and not by a module side effect, so a test may install it or leave it out; the rule lives in core and the painting in viewport - the new core/model/vectorPath.ts turns a shape into plain drawing commands (move/line/curve/close), closed rings being filled while all rings are stroked, a segment staying a line as long as neither of its ends carries a handle - a single handle is enough for a curve, the missing control point sitting on its own end, so a corner may stand next to a round side - and the way back to the first point is only drawn when it is curved, close doing it otherwise; holes go through one door only, Pixi recognising them from a GraphicsPath with checkForHoles, which tests containment rather than even-odd depth, which is enough for a ring inside a ring while without the flag the inner ring simply paints over the outer one (measured, see the counter-checks); the oversampling is the 2x from the plan - RenderTexture.create({resolution: 2}) puts 512 px on the GPU for a 256 canvas while texture.width stays the canvas size, which is the measure the sprite hangs on, and the render texture is the clip itself, so what juts out over the canvas is not in it and needs no mask; drawn pictures get the same sampler state as uploaded ones, setPictureFactory wrapping the factory for it, mirroring keep(); two measuring traps cost me runs - __gm.objectRect(id) gives the centre of the object and not its corner, so the first pass read four pixels next to the sprite and reported background while the rasterizer was correct, and the grid lines of the scene cross exactly in the centre point, so the hole check read #363940 and failed for the right reason, measuring beside it now; renderer.render() runs inside the picture request, which is safe here because every caller asks during its own widget redraw and the frame is drawn on the ticker afterwards, a nested render inside a running render pass would not be - that warning stands in the module head and in the notes; new module 47 with 8 own checks in its own lane (the picture on the GPU at double resolution measuring the canvas, the sprite showing the fill, the inner ring being a hole with the scene shining through, the later shape on top, the stroke running along the ring, a changed drawing getting a new key with the old one freed, and the sprite showing the new colour), the shapes being put into the model by mutate because the tab that draws them is stage 3, and 21 new unit tests in tests/core/vector-path.test.ts; three counter-checks hold: oversampling back to 1 fails the GPU check, checkForHoles off fails the hole check, and not drawing the curved way back fails a unit test; the full suite ran locally instead of only in CI because the change sits in TextureLibrary and touches every picture: ALL PASSED - 1165 checks, measured and carried into README and the wiki (#129)

adminandClaude Opus 5 bdb3f066cf The asset type "vector art" exists as a model, which is stage 1 of #129 and shows nothing in the browser yet on purpose: a vectorart asset is not placeable, sits in the + menu and in the asset panel with its own icon (a curve between two points) and has no tab, so it behaves like a font - selectable, its rows in the inspector, a double click leading nowhere - because the tab is stage 3 and half an asset would only be in the way; the data model in Asset.ts is a shape built from rings (even-odd, so a shape may have holes, answer 6 in the issue), a ring being points with optional bezier handles in/out stored as an offset from the point and a closed flag (an open path is stroke only, answer 4), plus fill colour, opacity and an optional stroke (answer 5) - the two handles are kept apart instead of mirrored, because what "smooth" means is the editor's business and not the model's; canvas width, height and the filter are properties, so they get an inspector row and undo like any other, while the shapes are intrinsic data like the frames of a texture; the revision that #185 hands to the picture path is a fingerprint of what is drawn, not a counter, which is exactly why that key took a string token - no command can forget to bump it - and the name of a shape is deliberately left out of it, renaming changing no pixel; six undo commands in the new vectorArtCommands.ts (add a shape numbered in order, remove one which comes back to its old place - unlike a tilemap layer the last one may go too -, rename, move, write the rings as one step per gesture with the list copied, and set the style where stroke: null takes it away) and the pure function shapeOrderTarget for the four buttons of the planned inspector list (one forward, to front, one back, to back), which also serves dragging in that list; loading from a project file is strict - a point without numbers falls away, a broken handle leaves a corner behind, duplicate shape ids fall away like duplicate layer ids, a stroke of width 0 is no stroke - while a ring with a single point, which is what someone is drawing right now, stays; three findings on the way: JSON.stringify as the fingerprint was wrong because the same drawing came back from a project file as {points, closed} and was built as {closed, points}, so a reload would have rasterized the same picture under a new key (the fingerprint writes its fields in a fixed order now and a test measures that case), toNumber in serialize.ts turns any nonsense into 0 so the Number.isFinite checks ran into nothing and {x: 'far'} became the left edge instead of vanishing (shapes read numbers strictly via asFinite, 0 being a place on the canvas here), and "Vector art" would have been both a menu entry and the panel heading, which an existing test catches because a click by text would hit the heading - the group is called "Vector drawings" now while the menu entry stays "Vector art"; 20 new unit tests in tests/core/vectorart.test.ts and three counter-checks hold: the fingerprint back on JSON.stringify fails 2, reading the numbers loosely again fails 4, and not copying the ring list fails 1; no e2e check and the check sum stays 1157, only module 04 counting 19 asset types instead of 18 (#129)

adminandClaude Opus 5 cb1804dcf2 A picture in the editor may now be drawn instead of uploaded, which is the piece #129 (Vector art) and #130 (Pixel editor) both need and neither could build alone: TextureRef.file has been a file name on the server, isTextureFile() checking a sha256 hash plus an extension and TextureLibrary fetching it over HTTP, so an asset that paints its own image had nowhere to put itself - the key now also takes the form gen:<assetId>@<revision>, which an uploaded file can never look like, and everything that only passes a ref along (sprite, tile, tilemap mesh, particle source, shaders, aspect ratio) is untouched because it still sees a Texture; the revision is a string, not a counter, which is the one deviation from the plan in the issue and costs nothing - gen:a1@7 and gen:a1@c0ffee go through the same door, so a generator may fingerprint its own content instead of relying on every command to remember to bump a number; two registries keyed by asset type as a plain string, so a plugin may bring its own type - registerPictureSource(type, read) in the new core/model/generated.ts tells the model canvas size and revision and resolvePicture() builds the ref from it (no rect, no slice, smooth from props.filter like a texture), and registerPictureGenerator(type, draw) in the new viewport/generatedPictures.ts hands out the finished texture, projectPictureFactory(() => state.project) tying the two together per session in App.ts; invalidation is a rule instead of guesswork at twenty call sites: GeneratedPictures<T> holds one picture per asset keyed on the revision and frees the old one as soon as the new is drawn, TextureLibrary destroying it and dropping the crops cut from it, while a generator that cannot draw yet is not remembered but asked again next time - the class imports Pixi as a type only, so the whole bookkeeping is measurable without a GPU; carried along are the picture picker (a drawn asset sits among the textures by name, without frames), the delete warning (counts tiles and animations for it too) and the asset context menu, where "Create sprite from picture" now covers it while "Create animation from texture" stays texture-only because it needs frames; one finding while probing - crop() could not have cut a generated texture at all, a RenderTexture having no source.resource to draw back from and drawImage running onto null, so it is handed out whole, a drawn picture having no sheet whose neighbouring row could bleed in; 18 new unit tests, 10 in tests/core/generated-picture.test.ts (building and splitting the key, an uploaded file is not one, no registry means no picture, resolving to canvas size, a new revision is a new key, a canvas without a size, the filter, the sprite size, picker order) and 8 in tests/viewport/generated-pictures.test.ts (drawing once, freeing the old revision and only for its own asset, null is not remembered, no key means nothing drawn, a session change gives everything back, peek), and three counter-checks hold: dropping generated assets from resolvePicture fails 5 of the 10 core tests, not freeing the old revision fails 1 viewport test, and narrowing the picker back to textures fails 3; no e2e check and the check sum stays 1157, because without a generator the groundwork shows nothing in the browser - that evidence comes with #129 (#185)

adminandClaude Opus 5 eac50e4194 Moving against a tilemap whose cells block with an outline no longer costs more than a whole frame: an outlined cell is its own polygon, split into convex parts, so a map that is a handful of merged rectangles when built from plain solid tiles is hundreds of solids under one entity - and Move brought every one of them into world coordinates and tested it exactly, including the ones on the far side of the map, which measured 148 ms per Move call on a 20x20 map with 16-corner outlines (34 ms at 8 corners, 0.4 ms with plain solid tiles), matching the report that standing still holds 60 fps while anything that moves stutters; the fix is a broad phase in two stages that decides nothing and only leaves out what cannot be reached - a move never ends further from its start than it is long, because sliding always shortens the rest, so every collider of the mover gets a rectangle grown by the move length and an obstacle whose rectangle does not meet it is never tested, a ray taking the rectangle around itself, and that rectangle is carried back into the map's own units with invert(m) and turned into cell coordinates (cellsWithin), a rotated map through its own axes, so a far cell is not brought into world form in the first place - solidShapesOf was O(cells) per call, which was the second cost block and the reason the 60x60 case still grew; CollisionSystem.overlaps takes the same range, so the editor run asks a map only for the cells within reach of the other side each frame, two maps narrowing nothing, and a Move obstacle now falls away at build time when its layer does not meet the mover's (#152) instead of inside the loop; the measurements after: 148 -> 0.26 ms, 34 -> 0.27 ms, 60x60 20 -> 3.5 ms, plain tiles unchanged; this is no regression of the recent commits - the same benchmark in worktrees against 947a6b1 (#141), 6a31f5e, 4f55f85 and ae3aa7d gives the same 85-148 ms, the cost has been there since outlined cells arrived with #141; new pure functions shapeBounds/grownBounds/boundsMeet in collider.ts and cellsWithin/cellsMeet in tilemapCollision.ts, 11 new unit tests in tests/core/broadphase.test.ts (the rectangles of all four shapes including a rotated box measuring its diagonal reach, touching counts as meeting, cellsWithin straight and turned by 90 degrees, a map handing out 400 cells without a range and under 10 with one, an 800 unit move from far away still stopping at the first cell, a rotated map blocking where its one painted cell was turned to, a ray across the whole map, and the editor run seeing a collider on a far cell), and four counter-checks hold: dropping the cell filter fails the counting test, padding without the move length fails 4 move tests, ignoring the rotation in cellsWithin fails 3, and a wrong range in the detection fails the touching test; one blunt test on the way - the first rotated map was painted on every cell, where even a wrongly computed cell range blocks and the counter-check stayed green, so exactly one cell is painted now and the test measures where it turned to; no e2e check and the check sum stays 1157, because a timing check in the browser would flutter under CI load while modules 40 and 42 cover the correctness anyway, the speed evidence being the node benchmark (#184)

adminandClaude Opus 5 ffdf0a8ddb The new node "Raycast all" answers with every collider along the ray instead of only the nearest one: it carries the same inputs and settings as Raycast (Ignore owner, Hit triggers, Layers from #158) plus "max hits" where 0 means all, and it hands back parallel lists sorted by distance - objects, colliders, points x/y, normals x/y, distances - next to count, so index i of every list speaks about the same hit; a collider counts once no matter how many convex parts its shape is built from, while a tilemap counts per cell it is hit in, and the filter sits in Solids.raycastAll like the one of #158, the one path the editor run and Play both take, so all 12 new unit tests run through describe.each against both systems; the node needed the value system to learn something it could not do - a graph list carried numbers, text, booleans and bundles but no object handles, asList turned an object into its name, so objects/colliders would have been lists of names, which loses the object when two carry the same name, and collider children usually do; Value now knows a travelling list that may hold handles and "Item at" gives such an item out as an object, ready for Destroy, Apply force or Name of, while the single door into a stored file - writeTyped/asTypeOf - runs the list through the new storedList() so every object becomes its name again and nothing living reaches a project file, which is its own unit test over JSON.stringify; three list nodes follow the handles: "Index of" compares objects by identity because a name is not the object of that name, "Set item" and "Fill" write an object as an object, and "Join text" prints the names instead of the innards; this decision was mine to make because the question ran into the MCP timeout - the alternative was a list of names plus "Object by name", which is the smaller change but lossy; 4 new e2e checks in the new block 43e (shield and floor in one go reading 2 and "145, 280", the second object answering to its name, which only a real object in a list can do, "max hits" 1 stopping at the nearest, and the node showing the row) and 18 new unit tests, 12 in raycast.test.ts, 4 on the value system and 2 in the node catalog; two counter-checks hold: not counting tilemap cells one by one drops 2 unit tests, and answering with the nearest hit only drops module 43 with 2 FAILs; one finding on the way - the node read "maxHits" while every other input carries a spoken label, because int() took the key as its label, so it has a third parameter now, and the e2e check caught that, no unit test did (#157)

adminandClaude Opus 5 0fdde6cb1e The Raycast node filters by collision layers: the node gained a "Layers" setting, a tickbox per collision layer of the project - the same field kind the collider uses for "Collides with" - and the ray only hits what sits on a ticked layer, tilemaps counting as colliders; the default is every layer, and a graph without the param answers exactly as before, which is its own unit test; the check is one-sided on purpose, unlike the symmetric rule of #152: a ray is not a collider, so it never reads the collidesWith of the thing it hits - a collider that meets nothing is still seen by a ray - because who a ray may look at is the ray's business, and a unit test holds that case; the filter sits in Solids.raycast in front of the intersection test, which is the one path the editor run and Play both take, so every unit test runs through describe.each against both systems; NodeView did not know the field kinds layer/layers, so the node would have read "Layers: 65533" - it now shows the name of the layer, or "All layers"; 5 new e2e checks in the new block 43d (a shield on its own layer between the caster and the floor stops the ray, the "Layers" row on the node, the tickbox menu with the project's layers, the ray reaching 280 instead of 145 units once the shield's layer is unticked, and the mask read as a name) and 6 new unit tests, three against each system; two counter-checks hold: disarming the filter line drops 6 unit tests and the unticking check in module 43, and switching the formatting off makes the node check fail with the raw bits; two findings from measuring came out of it and stand in the wiki and the notes - __gm.rays() only measures while the Scene tab is in front, so a node selection blinds it and the block measures through a Log node on distance instead, and a running behavior instance keeps the graph it started with, so the editor run casts with the old mask until the instance is built anew (#158)

adminandClaude Opus 5 4f55f85ad4 Collision layers and masks: a collider carries a layer and a mask of the layers it meets, and the pair only meets when both masks name the other's layer - the rule is one pure module (src/core/model/collisionLayers.ts) with layerBit, layersMeet and the names a project starts with, so the three places that have to agree read the same function: the editor run through CollisionSystem, the Solids sweep per pair and Rapier, where the mask becomes the collider's interaction groups; the project file gained collisionLayers: ["Default"] (default one layer, no formatVersion bump), the collider schema two new kinds - layer as a dropdown of the project's layers and layerMask as a menu of tickboxes that stays open while it is ticked (Menu.ts learned rows that do not close on a pick) - and the names are edited through "Collision layers..." in the toolbar's Project menu, not a Project tab, which is the decision I made myself because the question ran into the MCP timeout: the dialog (src/editor/CollisionLayersDialog.ts) holds up to 16 names, Add layer appends "Layer <n>" and Apply writes all of them as one undo step (SetCollisionLayersCommand); a mask read from a file goes through a check that refuses anything that is not a finite number, because Number(null) is 0 and a collidesWith: null would silently have meant "meets nothing"; 9 new e2e checks in module 8 cover the menu entry, the dialog, Add layer, Apply and its undo, both inspector rows, the tickbox menu, and the mover walking straight through the crate that 8c blocked on once their layers no longer meet, and 21 new unit tests cover the rule, the schema and the command (#152)

adminandClaude Opus 5 5ba796a2b6 Plugins belong to the project, and they load before it: the project file gained the field plugins: ["demo-plugin.js"] (default empty, no formatVersion bump), the Plugins tab's switch writes into it as an ordinary undo step (SetPluginActiveCommand) instead of into a server-wide plugins.json, and the start order is turned around - startPlugins only fetches the list of files, then editor.boot() runs and ProjectStore.load(id, prepare) hands the raw JSON through before it is deserialized, where pluginsOf(raw) reads the list and PluginManager.syncTo() activates exactly those; that is the point of the issue, because what a plugin registers has to stand there before normalizeGraph would throw it away as unknown (#126, #127), a project switch first stops what the new project does not name and then starts what it does, a file the server does not have is passed over silently, and after signing out the manager is dead so a late event cannot start anything in a torn-down session; on the server plugins.json, PluginStore::setActive, isActive, the route PUT ?r=plugins/{file} and the 403 for inactive modules are gone and GET ?r=plugins only answers {file,bytes,updatedAt}, which makes every plugin file fetchable - the consequence accepted in #117, written down in the wiki for #115 and #116; publishPlugins(root) only copies files now, the seeder switches the demo plugin on in the fixture project, and the Plugins tab carries a puzzle piece as its icon while only a plugin's own tab still goes without one (the knob and the socket are cubic curves, not arcs, which Pixi's parser draws as a spike after an L); 3 new e2e checks in module 38 and 5 new unit tests cover the project as the owner of the switch, its undo, the order, pluginsOf against crude input and an unknown file name (#119)
