@t3x-dev/transition

Public alpha contracts for verifiable T3X state transitions.

@t3x-dev/[email protected] is part of the public T3X alpha release surface.

What

@t3x-dev/transition exposes the protocol nouns used by T3X: State, Effect, Statement, and CommitV2. It also includes canonicalization, object identity, parsing, Replay verification, and commit integrity helpers.

Why

Third-party agents, MCP tools, and integration code need a small package that can reason about T3X transition objects without depending on the WebUI, API server, database, runner, or local installer.

The package is intentionally a leaf protocol surface. It does not include network, storage, LLM, clock, random, or product UI behavior.

Install

npm install @t3x-dev/transition

Sample

import {
  InMemoryObjectResolver,
  describeProtocolObject,
  verifyCommitIntegrity,
} from '@t3x-dev/transition';

const resolver = new InMemoryObjectResolver([baseState, effect, proposal, decision]);
const result = await verifyCommitIntegrity(commit, { resolver });

console.log(describeProtocolObject(result.result));

Use this package for protocol-level verification. Use the T3X application or higher-level packages for product workflows.
