wasm-binding

This directory is a minimal TypeScript adapter shell for a future Rust/WASM binding.

It is intentionally not a calculator implementation. The wrapper only:

• loads a future wasm-pack-style module
• validates the exported surface
• provides a safe boundary for downstream callers

Formula logic stays outside this package. When the Rust/WASM build becomes ready, the generated output should be wired into the adapter here rather than duplicating the calculator rules in TypeScript.

Browser demos that use this package must use synthetic data only. Do not place PHI, patient-level records, secrets, tokens, or private study data in fixtures, bundles, screenshots, logs, or example payloads.

Current status

• No Rust build pipeline is defined here yet
• No funding formulas are implemented here
• The package is a scaffold for future wasm-pack output
• Not publication-ready and not published to npm

Suggested shape

The adapter expects a module factory so callers can plug in future WASM output without changing the wrapper contract:

import { createWasmAdapter } from './src/index.js';

const binding = await createWasmAdapter({
  moduleFactory: () => import('../pkg'),
  validateExports: (candidate): candidate is { calculate: (input: unknown) => unknown } =>
    typeof candidate === 'object' &&
    candidate !== null &&
    typeof (candidate as Record<string, unknown>).calculate === 'function',
});

That keeps the TypeScript side focused on loading, validation, and handoff.
