- title: External graphs
|

details: JSO and FXNode addons serialize DAGs to the S-expression AST consumed by the worker.

## The entire boundary
|
|
|
|
```js
|
|
const color = await core.allocateRows({
|
|
name: "triangle.color",
|
|
rows: 1,
|
|
stride: 16,
|
|
format: "f32",
|
|
});
|
|
|
|
color.write(0, [0.2, 0.65, 1, 1]);
|
|
color.row(0)[0] = 0.8; // direct SharedArrayBuffer write
|
|
await loadGraph(core, graph); // infrequent message
|
|
```
|
|
|
|
`@yawn/core` contains only the public shared-row client and its worker. The worker owns the fixed 64-byte-aligned arena, S-expression graph compiler, WebGPU loadout, and transient texture aliasing. Every scene convention and every byte of WGSL comes from an addon or application.
|
|
|
|
```text
|
|
JSO / FXNode ──▶ AST ──▶ S-expression ──▶ core worker ──▶ WebGPU
|
|
any JS thread ───────────── direct SAB row writes ────────────┘
|
|
```
|
|
|
|
The addon packages provide graph serialization, optional WGSL, glTF import directly into shared rows, and conventional camera/material/mesh handles. None of them add semantics to core.
