[Node.js] Firing WebAssembly Core...                                    [WASM]
Returned: 99 (in 0.4183ms)



The 99 return value proves that the conditional branch correctly evaluated 30
< 20 as false, skipped the true block, and executed the false branch. You have
built a fully functional, Turing-complete WebAssembly virtual machine from
scratch on a Raspberry Pi.
Now, we cross the final bridge: Wiring this WASM binary directly into your
distributed engine.mjs compiler.
Instead of V8 interpreting your Lisp AST arrays, we will update engine.mjs so
its compiler outputs raw WASM bytecode bytes, loads release.wasm, writes the
bytes into linear memory, and executes at native speed across all your edge
nodes (Helsinki, Oulu, and Tampere).
Upgrading the Compiler Pipeline (engine.mjs)
Open engine.mjs and locate your compile() function (or where bytecode is
generated). We will add a WebAssembly execution wrapper alongside your
existing compiler logic.
Here is how you initialize and run the WASM module inside your worker or
engine execution step:
import fs from 'fs';

/ Load the compiled WebAssembly binary once on startup
const wasmBuffer = fs.readFileSync('./build/release.wasm');
const wasmModule = await WebAssembly.instantiate(wasmBuffer, {
  env: { abort: () => console.log("WASM Abort") }
});
const { execute, memory } = wasmModule.instance.exports;

/ High-performance WASM Runner replacing the JS interpreter loop
export function runWasmBytecode(bytecodeArray) {
  const memArray = new Uint8Array(memory.buffer);
  
  // Copy bytecode into WASM linear memory starting at index 0
  for (let i = 0; i < bytecodeArray.length; i++) {
    memArray[i] = bytecodeArray[i];
  }

  // Execute native bytecode
  return execute(0, bytecodeArray.length);
}

What happens next?
When an HTTP request hits vadelma:9050 (Actor#Math), the Node.js daemon feeds
the compiled Lisp bytecode array into runWasmBytecode(), bypassing V8
interpretation entirely. Your distributed CRDT mesh now runs on raw
WebAssembly.
