Stop animation gets a blend (s) port that fades the animation back to what
lies underneath. Play animation gets blend out (s) for Once (reset) and a
restart port that starts a running, paused or fading animation from frame 0.

The Animation tab shows the root asset over the timeline, with every row's value at the
playhead written onto a copy of it – the sprite, text or container placed at the origin as a
scene would place it, a scene as itself. Rows reach the root through that placed object and its
children through the object's instance edits, the route a placed container's content takes,
so the ids match what the runtime gives them. The runtime player and the preview evaluate a row
through one function (trackWriteAt), relative rows included; past the end of a once-reset pass
the preview shows the starting values, as the player would. Play, pause and the ruler drive the
preview through the timeline's playhead; a drag pans, the wheel zooms, Centre frames it. The
document is never touched and undo never hears of scrubbing.
On animation finished no longer describes itself as hearing "a sprite of the owner".

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

Load scene sets a flag on the World like Stop and Restart do; the swap
happens after the tick, and the last wish of a tick wins. Exactly one
thing crosses over: the SharedState, so global variables and global
machines keep what they know while everything local is built anew.
Loading the scene that is already running rebuilds it, which is what
"reset the level" means when the score must survive.
A run starts either from the start scene (a new project field, set from
the asset panel and marked with an arrow in the list) or from whatever
scene is open. The toggle next to Play says which question is asked and
remembers the answer in localStorage: it is a way of working, not part
of the game.
Sounds no longer end because a scene ends. A voice belongs to the
behavior that started it and stops right after On destroy, so the scene
swap is no longer a special case at all. For the enemy that plays its
explosion and destroys itself in the same breath there is now a
detached input on Play sound.
The scene selector stays usable while a run plays, because a double
click in the asset panel already did the same thing unguarded. It moves
what the editor looks at, not what the run plays.
Sounds follow the road fonts already paved: the file goes to the server
content-addressed under its sha256, the project keeps a named asset that
points at it, and nothing is ever re-encoded. The format is read from the
file's own signature, not from what the browser claims - the same .m4a
arrives as audio/mp4, audio/x-m4a or as nothing at all.
Playing is two nodes. "Play sound" takes the asset and may raise or lower
its volume; every call is its own voice, so two jumps in a row are two
jumps heard. Its loop input is a choice of three - from the asset, on,
off - because a checkbox has to spend one of its two positions on "not
set" and would lose a case: an asset that loops could then never be
played once.
Below the graph core stays browser-free: NodeContext hands out an asset
id, BehaviorSystem resolves it against the project and folds the asset's
own volume and loop into the call, and only viewport/SoundLibrary knows
about Web Audio. A run without a sink plays nothing instead of throwing.
The CI browser is muted, so the ear is no witness: the debug hook counts
started and stopped voices, and step 34 reads that counter.
Four issues that all reach for the same line: how the current state is
read and written. Splitting them into four commits would mean four
states of the tree that do not compile, so they arrive together.
#55 start state — the machine asset carries an optional `start` holding
a State node's id. Right-click a state to set or remove it, a ring in
the node's title says which one it is. A dead id (the state was deleted)
reads as "no start", so nothing has to clean up after a deletion.
#53 entered/exited — `On state entered` and `On state exited`, one exec
output per state. Every change now goes through a single `setState`
that reports it; BehaviorSystem delivers it after the exec flow that
caused it, `exited` of the old before `entered` of the new, round after
round until the queue is empty, with a cap that stops a ping-pong graph
with an endless-loop error. A local machine tells the instance that
switched, a global one tells every instance holding a matching event
node. The start state fires `entered` too: per instance for a local
machine, once per run for a global one.
#57 reading — `Current state` with `name` for showing and `id` for
comparing, `Is in state` with one boolean per state. Neither has a
`run`, so `read` learned `def` and `lookup`, and the catalog test knows
this third kind of node.
#54 seeing it — during a run the state machine tab marks every state
some instance is holding faintly, and the one held by the selected
scene object's instance strongly.

This reverses the design of the previous commit. `PropertyDef.scope` is gone
without replacement: a behavior variable is an object property again, without
exception, and sharing is something you point at rather than something you
declare twice.
A **Variables asset** is declarations and nothing else -- no graph, no position,
never placed, no tab of its own (`TAB_OF_ASSET` is already `Partial<>`, so that
costs no line). A `Variables` node names one through its new `variablesAsset`
setting, empty meaning the behavior's own variables as before, and then reads
and writes one value per key for the whole run. Its property list follows the
chosen source, which was the actual request: a value another graph declared is
now offerable, where before every participant had to declare the name itself.
That deletes more than it adds (-72 lines net): `globalConflicts` and its
run-stopping kind clash, `SetVariableScopeCommand`, the scope picker, both
object-inspector filters and the "shared by the whole run" note on the placed
object. A typo is no longer a silent second variable -- naming an asset is
picking from a list. And two Variables assets may carry the same key without
meeting, because the asset is the key, not the name. The one shape it copies is
the one that already existed: `Set state` picks its machine the same way.
Lifetime is unchanged. The bag is built at `BehaviorSystem.start()` from the
declarations and never written back, so playing in the editor cannot change the
project -- which is the whole reason a counter must not be an object property
(`World.syncToModel` would `commit()` it, and the coin counter would stand at 7
for good).
Full symmetry across that gap, without mirroring anything. Two named wires:
`Inspector.liveVariables` shows the values as they stand while a run is on and
falls back to the declarations when it ends, and `adoptDeclarations()` takes a
key into the run *only where the document changed it since the last sync*.
Without that condition any unrelated project edit would snap a running counter
back to its starting value; a counter-test bends exactly that and falls over.
Nothing was ever cached, incidentally: `GraphInterpreter` only pulse-caches
nodes without a `read`, and the variable node has one. The wire was missing.
The state machine `Scope` row is now an ordinary `enum` row through
`createFieldRow`. It was hand-built from an `HStack` with a ghost dropdown and
began ~34px left of every value above it; the explanations beside `Local` and
`Global` are gone from the menu, the sentence below the row keeps saying it.
Machine scope is otherwise untouched -- `StateMachineAsset.scope`,
`SetMachineScopeCommand`, `stateBag()` and its persistence all stand, so #59
stays closed as built and `Scope` as a type now carries machines alone.
Six counter-proofs, each biting at its own guard. One of them did not bite at
first: the suggestion list was computed twice, in `nodeSection` and
`portSection`, so only the browser test covered the request itself. It is one
named function now, `variableChoices`, with a unit test of its own.

A variable or a state machine declared `global` keeps one value for the whole
run instead of one per behavior instance. The scope sits on the declaration --
`PropertyDef.scope` and `StateMachineAsset.scope`, both optional, absence
meaning `local` -- and `local` is never written, so every project made before
this saves back unchanged.
**The name is the key.** Two behaviors declaring a global `score` mean one
variable; a behavior declaring `score` locally keeps its own. Kinds that
disagree about one global name stop the run before it starts, with the two
behaviors named; starting values that disagree are a warning on the behavior
that declares it, and the first declaration wins (`globalConflicts`).
The runtime needs no redirection layer. A global variable falls out of
`schemaForObject`, so it never reaches `entity.props` -- and then the whole rule
is "whoever declares the name takes their own value" (`graph/sharedState.ts`).
The `Variables` node is untouched and stays transparent: switching a variable to
global breaks no existing graph, because `GraphInterpreter.readAll` builds a
fresh object per read anyway and only asks `port.key in all`.
That same cut answers the inspector. A shared value has no owner, so the placed
object shows no row for it and can hold no override -- `SetVariableScopeCommand`
takes the deviations that were there and undo gives them back.
Both places say it in words rather than leaving a glyph to be guessed: the
declaration explains the mark below the list, and the placed object names the
variable it no longer holds instead of claiming the behavior declares none --
which is what it said before, untruthfully. Screenshots of the e2e run turned
that up; no check had been looking at it.
`SharedState` hangs off `NodeContext`, is built in `BehaviorSystem.start()` from
the *declarations* rather than from any instance (a global variable exists
before its behavior is placed), and is thrown away with the run: nothing is
written back, not even in the editor run. `GraphInterpreter.call` passes it on
through `...ctx` while nested calls keep getting fresh local variables, which is
why `program.defaults` is stripped of global keys.
Two traps this hit. `defSignature`/`assetSignature` have to carry the scope or
the inspector does not rebuild after the switch -- and a state machine has no
rows at all, so its scope is appended to the signature by hand. And the object
inspector does not go through `schemaForObject` for behaviors, it reads
`asset.variables` directly; filtering in one place was not enough, and no unit
test covered that path. The e2e caught it (`global: true` where false belonged),
and the rule now lives in one named function, `objectRows`.
Scopes `object` and `scene` are deliberately not built. The object case already
has a route (`Object by name` -> `Properties`), and a run knows exactly one
scene, so `scene` would be indistinguishable from `global` until #39 exists.
Closes#59: a machine's scope is a word on the machine asset, not a setting per
`Set state` node, so the same machine cannot live in two places at once.

The asset type `particles` is placeable and carries a graph at the same time —
`behavior` was the blueprint. Because a continuous emitter gives birth to particle n
at time n/rate, the whole field is a function of the clock rather than of the frames:
no ring-buffer bookkeeping, exact time jumps, reproducibility as a measurable property.
compile.ts follows compileShader's frame but emits JS closures into a Float64Array
instead of GLSL, and without eval; a node with two consumers is evaluated once.
Drawing is one Pixi ParticleContainer per source, so one draw call.
Collision, wind and braking in flight are out for good — that is the price of the
formula model, not an omission.
The tab count goes from nine to ten, which is exactly the case #84 was built for one
day earlier: at 1280 px the row no longer holds every tab, so guard 14b now asks for
hidden.length > 0 instead of === 0.
Four new rows on sprite, text, collider and container (block TRANSFORM):
scale, rotation in degrees clockwise, mirrorX, mirrorY. As properties they
get override/reset/apply, loading of old projects, write-back after play and
the Properties node for free; camera and behavior have none.
The hierarchy composes T*R*S per level (composeAlongChain replaces
sumAlongChain), so children rotate and scale with their parent. Reparenting
and grouping keep the look (carriedTransform). Drawing goes through
placeNode, the gizmo is a polygon, cull and objectRect use the AABB, drags
are computed in the parent's system.
Colliders are oriented boxes: SAT for box/box, box-circle in the box frame;
exitDistance replaces axisSeparation/axisCorrection, moveAndSlide moves along
the object's own axes.

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

Order per instance: On start -> On enable -> On update ... -> On disable
-> On destroy. On enable fires right after On start and whenever the
behavior comes back on (itself and its parents); On disable in the frame
it goes off, the instance stays frozen. On destroy fires when the entity
leaves the world (Destroy node, child of a destroyed object) and when the
world is torn down on stop/restart, preceded by On disable if still on.
A new On start node added while playing still does not fire for a
running instance (kept as is, documented in the wiki).

A state machine is an asset whose graph holds one `State` node per state
(no ports, name as title), edited in a new "State machine" tab that reuses
the graph canvas: right-click places "State n", snap toggle shared with the
Behavior tab via SnapToggle. `statemachine` is a value kind like texture
(port, literal node, variable, struct field, tagged list item).
Behaviors use it through `State branch` (one exec output per state) and
`Set state` (one exec input per state; the interpreter now hands `run` the
entry port). States live per behavior instance in NodeContext.states, with
no initial state. Ports derive from the inline picker or a wired
`State machine` literal; BehaviorLookup became GraphLookup with
behavior(id) and machine(id).
The Graph tab is labelled "Behavior" (key unchanged). Unit tests
(state-machine, kinds, catalog, ports), e2e step 26 and README added.

- `.gitignore` said `index.html` unanchored, which also caught the Vite source page;
a fresh clone could neither `dev` nor `build`. Anchored to `/index.html`, page added.
- Removed GM_REMOTE (tools/remote/gm-browser.ps1 and the ssh/scp branch in browser.mjs):
the Windows test machine is gone and the only flaky check that lived on it is closed (#37).
- Removed `npm run preview`, undocumented and unused.
- Comments: wrong number in collider.test.ts (250 → 200), the "declarations used to…"
history in listItems.ts and friends, the 24 px/28 contradiction, section banners in
nodes/index.ts, node-catalog.test.ts and api/index.php, name paraphrases, and the stale
step numbers in tools/e2e/11-…23- from the old global count.
- README: asset types include `animation`, kind order Number/Text/Boolean, tagged colour
and texture items, 6/5 kinds, the `Texture` node, `./build.sh`, PROJECT_FORMAT_VERSION,
and the file tree (kinds.ts, listItems.ts, propertyPorts.ts, Breadcrumb.ts, beads.ts,
tools/assets/).
- tests/helpers.ts takes the duplicated `findObject` and `sceneWithCamera`.

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

The graph was only locked by five edit-mode guards in GraphCanvas. The
running game reads the graph by reference each frame, so a new node, edge,
changed value, disconnect or undo takes effect from the next frame. Stop
discards these edits like everything else changed in play. A new On start
node does not fire for a behavior that has already started.
During play every data output shows the value it last produced, in the
highlight colour and refreshed ten times a second. Values are kept per
graph, because node ids are only unique within one; with several
instances the most recent value wins. The Variables node reads the live
variable bag, so only its own outputs are kept, as a snapshot.
Each time an exec edge fires, a bead runs along it in 0.3 s, at most one
every 0.15 s per edge, following the same curve the edge is drawn with.
Beads run on game time and freeze while paused; the game logic is
unchanged.

Split GraphCanvas (1076 -> 831 lines) into EdgeLayer and graphMenus;
the port and marker menus were the same list and are now one function.
Value specs of the inspector and the list tab share valueSpecs.ts, and
the remaining copies (compound commands, type glyphs, typed asset
lookup, name rule, play/editor world setup, marquee) are merged.
Four copies had already drifted apart; merging them fixes:
- "Disconnect N links" in the port menu is one undo step, not N
- "+ Add collider" is hidden on a placed container instance, as in
the hierarchy menu, instead of always failing
- a bool property coerced from the text "false" becomes false
- a port command on an unknown node type reports instead of crashing
Comment-only edits leave the bundle byte-identical. README corrected in
35 places (step limit, jump-run clock, suite duration, 409 body, ...).

PropertyValue was number | string | boolean | list. A struct joins it, which
costs two things the typechecker found rather than I did.
An object on a data edge used to mean a live entity, so asEntity would have
taken a struct for one and asString would have read .name off it. EntityHandle
now carries a symbol brand – a symbol so no field name can impersonate it, and
it never serializes, which suits a thing that exists only while the game runs.
It is built in exactly one place.
String(value) would have written a struct as [object Object] at 39 call sites.
They go through textOf(), which is identical for primitives.
normalizeGraph dropped everything but primitives from node params, so the List
node lost its value on every save ([3,1,4] round-tripped to undefined).
Variables were spared: they have a schema, params have none.
objectSection.ts had grown to 559 lines around three separable parts: the
queries, the vector rows and the parent row. Four object commands repeated the
same capture/restore preamble – applyCommands stays out, its five carry extra
undo state whose restore order matters.
58 dashed banner comments are gone. The nine labels in nodes/index.ts stay:
they are the only structure a flat 90-entry array has.

A held key fired once and then nothing, so sliding a Tetris piece sideways or
walking a menu meant building a timer next to every key node. Two settings on
the node do it now: Repeat after and Repeat interval, both in milliseconds so
the usual values stay whole numbers (300, 50) instead of 0.3 and 0.05. A delay
of 0 keeps the node exactly as it was, an interval of 0 means every frame.
The browser's own auto-repeat is deliberately not used - Input.press has always
dropped it - because its delay and rate are an operating-system setting of the
player's, not a game's. The repeat is built from the measured hold time instead,
per node, so two nodes on one key keep their own clocks. The rule itself is a
pure function in keyRepeat.ts and is checked without a world.
Both rows stay off the node body while the delay is 0: two lines of "0" on every
key node in every graph would be noise, and the screenshot said so. NodeDef gains
hiddenParams for that; the inspector still shows them.

A behavior that has a Start and an End node can now be dropped into any
other graph as a node of its own. What is declared on the start node
becomes the inputs of that node, what hangs on the end node its outputs;
the port list is derived from the sub graph, not copied, so declaring a
port in one graph grows the node in the other without touching it. The
node carries the behavior's name and the palette lists behaviors by
name, so a call is one grab instead of a node plus a dropdown.
An embedded behavior has no object and therefore no place for
variables: every call starts on the asset defaults and communicates
only through its ports. That is the conservative direction - state can
still be added later, and shared state already has a home in a behavior
object in the scene. Node ids are unique per graph only, so each call
gets its own pulse cache; without that, two graphs would collide.
Renaming a port used to silently drop the value typed on the calling
node. It is carried along now, project wide, like the edges.
Pause is a sub-state of play, not a third mode: the toolbar button and
Ctrl+Enter stop ticking the world, the clock included. A held frame still
drops the input edges, so resuming does not fire a pause worth of keys in
one go.
The editor run missed the case it is most wanted for. hasEditorRun only
looked at the stored scene objects, so a behavior inside a placed
container never started one; the world now builds from resolveObjects and
writes back through objectRef, keeping the move as an instance edit
instead of baking the instance out.
Keys and clicks go to the run while the Game tab is on screen, where no
key means anything to the editor, and are handed back on leaving it -
held keys released, so nothing keeps walking unpressed.
A behavior object carries a "Run in editor" switch next to Enabled. When
it is on, the behavior ticks outside of Play and works on the saved model
directly - Unity semantics: what it moves is a real change, autosaved and
not undoable.
Input stays with the editor, so On key never fires while typing. The
editor run never bakes placed containers into the model, since that would
silently drop their instanceEdits.
syncToModel reports whether it wrote anything, and the dirty flag is only
raised on change - otherwise a behavior moving something every frame
would trigger ~60 saves a second.
The game view took whatever camera came first in the scene, ignoring the
switch, so `enabled = false` on a camera did nothing and a second camera
never got its turn. `World.activeCamera()` now decides: of the cameras
switched on – the whole parent chain counted, as for any object – the
first in hierarchy order, and none on renders nothing at all. It is asked
per frame, so a graph switching cameras hands the view over immediately.

A scene now stores only the container object; its content is resolved from
the template on every read, with deviations kept as sparse instanceEdits on
the container object. This drops the propagation bookkeeping entirely --
templateSync.ts is gone and the three structural gaps (add, remove, reparent)
cannot diverge any more.
Values stay editable on an instance, structure does not; Unpack writes the
content into the scene, keeping ids. Play mode bakes containers into the
throwaway copy before entities are built. No migration: formatVersion is 2
and the seeders write the new format.

Tooling:
- Prettier as the single formatting authority (110 columns, single quotes,
measured against the existing style); Markdown excluded because table-cell
padding turns the README glossary into 1000-character lines.
- Type-aware ESLint ending in eslint-config-prettier, so a rule always means
"this is a bug", never "this looks different".
- .editorconfig and an `npm run check` that runs typecheck, lint, format and
tests in one go.
Findings fixed on the first run: three more duplicate imports, four
String(unknown) calls (parameter types narrowed instead of casts), two dead
initialisers, two redundant casts, a console.log for a real error. Two
warnings were false here and are disabled with a reason in place.
Tests 132 -> 269:
- node-catalog.test.ts covers every node with a run(), with a guard that fails
when a new node has no row.
- behavior-events.test.ts covers the ten event nodes through a running World,
checking timing rather than existence.
- Input's state machine (press/release/releaseAll) is reachable without DOM
events now; the DOM handlers are thin adapters.
Compare fell back to == without a configured operator although the schema
default is <; aligned.

- SceneObject.editorOffset (x/y): shifts only where an object is drawn in
the Scene tab, cascades to children, undo-able with a reset action.
Never written into container templates.
- On click without an owner now fires for any click inside the camera
frame instead of hit-testing the (editor-only) behavior symbol.
- seed-jumprun: coins are a "Coin" container (sprite + trigger), nested
containers are expanded recursively, Destroy targets the coin's parent,
and the clock uses a Ceil node instead of ToText.

Engine additions that the example game needed:
- `enabled` as a shared property of every placeable asset (default on, an
override on the scene object). A switched-off object is not drawn, does not
collide and its behavior does not run - and neither does anything parented
below it. Disabled objects are now hidden in the scene view as well, so the
editor shows what the game shows; they stay in the hierarchy panel, which is
where they are selected and switched back on.
- Asset type `text` (text, fontSize, color, align), rendered in scene and game.
- Pointer input in the game view: `On click`, `Mouse position`, `Mouse button`,
`Is hovered`, hit-tested against colliders, else sprite/text footprints.
- New nodes: Set/Is enabled, Set text, Is asset, Name of, Equals, To text,
Join text, Floor/Ceil/Round, Modulo, Random, Time, Restart game.
Tooling: shared CDP harness (tools/harness.mjs), central project registry with
a guard that keeps destructive scripts off the playground (tools/projects.mjs),
plus smoke suites for the demo scene and the jump-and-run game.

Move with "Collide with solids" now steps in sub-steps of at most half the
thinnest collider, so a fast step can no longer jump across a collider (the
crates are only 60 high, which is why it showed up mostly on the y axis). A
pre-existing overlap is still never resolved, but it can no longer be
deepened either, so a small overlap cannot open a wall permanently.
seed-demo.mjs now writes the saved demo scene: a "Player" container (green
sprite with collider and the Mover behavior) against two "Enemy" container
instances, camera at zoom 0.5, Spawner dropping another enemy on Space.
The e2e checks assert against the old two-crate layout and locate widgets by
text, which the demo can no longer provide (three identically named sprite
instances, both crates nested in containers). Its fixture therefore moves to
tools/seed-e2e.mjs so the shipped demo can evolve without rewriting 100+
checks: seed-e2e -> e2e -> seed-demo.
