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.
A font asset holds a file and nothing else, the twin of a texture: the server keeps it
content-addressed under data/fonts/{sha256}.{ext}, with the format read from the file's own
four-byte signature (finfo reports fonts inconsistently across libmagic versions). A text
wears one through its ordinary Font property, so overrides, reset, undo and the Properties
node come for free; no font means the editor's own typeface.
The picker lists everything the server holds and renders each row in the face it offers.
The family name is gm-font-<hash16>, never the name inside the file, so two "Regular" cannot
collide. WorldViewport.syncText is the single place that draws it, which covers scene, game
preview and play at once.

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

A single node now lists any number of variables. Every entry is an output
that reads the current value whenever it is pulled; an entry switched to
Set is also an input and is written when the flow arrives. Exec pins only
exist while at least one entry writes, and all inputs are read before any
write, so one node can swap two variables.
Get/Set variable, Get/Set variables and Variable are gone. Old project
files are converted on load: each old node becomes a Variables node with
the same variables, edges and typed values.
A written port without a typed value now shows the zero of its kind on
the node body, matching what the inspector shows and what the run writes.

Next move held four clusters of Set variable in a row, fourteen single nodes
in all; clear-lines read three variables one after the other. They are now
one plural node each, which takes Next move 40 -> 30 nodes and clear-lines
25 -> 23. Every remaining single node was checked and really is single: ok/no
are the same variable in opposite branches, take/keep the same one across a
write, and the three key setters hang on three different events.
Two contracts carry those merges, both pinned as tests. Set variables writes
per port with writeTyped exactly as the singular node does, so a Pack{rot}
still merges instead of overwriting - without it, turning would have erased
the other three fields. And the interpreter collects every input before the
node runs, so no input may come from a variable the same node writes; a data
node is evaluated once per pulse and keeps its answer. That second rule is
invisible in the game, because OnUpdate re-reads each frame and heals it, so
it lives in a unit test rather than in the smoke.
/opt/node22 and /opt/npm are gone from the tree. build.sh ran into the empty
path once they were moved away; the other seven mentions were documentation.
e2e.sh and check.sh replace the bare npm calls. A long run does not survive
the end of its shell - four full e2e runs died mid-suite with oom_kill 0 -
so e2e.sh start hands the run to a transient game-maker-e2e.service, which
does. e2e.sh status reports the running job or the last result, and calls a
log without a closing line ABORTED rather than reporting the passes it got
to. Both scripts end on an explicit exit line, because set -o pipefail inside
a script does not protect the caller: measured, ./check.sh | tail still
reports 0. Logs carry a timestamp and land in logs/, which is ignored.

The aspect button now carries two offers, so it becomes a menu: fit one
side to the texture ratio, or set both sides to the exact pixel size as a
single undo step.
Dropping a row on the outer quarter of another row inserts it into that
gap instead of parenting into it, reordering among the siblings there.
Order is the stored order, so ReorderObjectCommand is a splice; equal z
falls back to tree order, which makes this the way to draw one object in
front of another. Rejected on container content like the other structural
edits.

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.

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.
