ManifestoDeterministic State Protocol

Define meaning once — derive UI, backend, AI, and full history as projections.

🎯

Deterministic

Same input → same output. Always.

🔍

Accountable

Every change traceable to Actor + Authority + Intent.

👥

Actor-Agnostic

Humans, AI agents, and automated processes share the same interface.

⚡

Effect Isolation

Pure computation separated from IO.

Quick Example ​

mel
domain Counter {
  state { count: number = 0 }
  action increment() {
    onceIntent { patch count = add(count, 1) }
  }
}
typescript
import { createApp } from "@manifesto-ai/app";
import CounterMel from "./counter.mel";

const app = createApp({ schema: CounterMel, effects: {} });
await app.ready();
await app.act("increment").done();
console.log(app.getState().data.count); // 1
