sealed-lattice

sealed-lattice is a browser-native TypeScript package for post-quantum voting research prototypes.

The current implementation ships:

• a real sha256Hex helper on the safe root package
• a typed UnsupportedRuntimeError for missing Web Crypto support
• a hardened repo, docs, testing, and publish workflow around that narrow surface
• a deliberately narrow public surface while the lattice-native architecture is still being proven

This repository is a hardened research prototype. It is not audited production voting software.

Release status

This repository currently tracks the initial public sealed-lattice surface.

The public surface is intentionally narrow while the repo, CI, docs, tests, coverage, and packaging experience are stabilized. Lattice cryptography, threshold flows, transport payloads, proofs, protocol types, and any future subpath structure are still being designed and are not frozen yet.

Installation

pnpm add sealed-lattice

Runtime requirements

• Use ESM imports such as import { sha256Hex } from 'sealed-lattice'. The published package does not expose CommonJS require() entry points.
• Browsers need globalThis.crypto.subtle and TextEncoder.
• CI validates Chromium, Firefox, and WebKit on desktop, plus Chromium and WebKit in mobile emulation.
• Node requires version 24.14.1 or newer with globalThis.crypto.

Safe quickstart

import { sha256Hex } from "sealed-lattice";

const digest = await sha256Hex("sealed-lattice");

console.log(digest);

The root package currently exposes only sha256Hex and UnsupportedRuntimeError.

Public package boundary

• sealed-lattice

No additional public subpaths are promised yet. Future capability areas such as runtime helpers, serialization, transport, threshold coordination, proofs, and protocol types remain internal design space until the post-quantum flow and misuse-resistant contracts are stable.
