# MUJ428 Trust Layer

> MUJ428 Trust is independent trust infrastructure for consequential AI-agent actions. It is designed to verify that the action an agent was authorized to take is the action that actually occurs.

## What MUJ428 Trust does

AI agents can purchase, pay, approve, write, delegate, release, accept, and commit on behalf of people and organizations. MUJ428 adds an integrity layer between authorization and execution so approved intent can be checked against actual effect.

The model is simple: **verify before act, then verify what happened.** MUJ428 can bind exact intent, action arguments, authority, evidence, freshness conditions, and execution premises into a Trust Receipt. A Verified Effect records the resulting state.

MUJ428 does not take custody of the underlying transaction principal. The buyer, seller, agent, platform, or payment system remains responsible for the actual transaction or side effect.

## Problems it targets

- **Intent drift:** make the approved action and arguments explicit and checkable.
- **Stale evidence:** treat evidence, policy, resource state, and precondition freshness as part of the trust decision.
- **Replay and duplicate effects:** handle retries, idempotency, and uncertain outcomes explicitly.
- **Weak proof after execution:** record what effect actually occurred, not only what an agent intended.

## Built for humans and machines

The public MUJ428 Trust site includes a human product interface plus REST, MCP, A2A, OpenAPI, Agent Card, and other machine-readable discovery resources.

For people, the core point is straightforward: **MUJ428 is designed to make consequential AI-agent actions more inspectable, deterministic, and verifiable.**
